Oxygen defects formed at the boundary between the zinc oxide type oxide semiconductor and the gate insulator are terminated by a surface treatment using sulfur or selenium as an oxygen group element or a compound thereof, the oxygen group element scarcely occurring physical property value change. Sulfur or selenium atoms effectively substitute oxygen defects to prevent occurrence of electron supplemental sites by merely applying a gas phase or liquid phase treatment to an oxide semiconductor or gate insulator with no remarkable change on the manufacturing process. As a result, this can attain the suppression of the threshold potential shift and the leak current in the characteristics of a thin film transistor.

A phenomenon of change of a contact resistance between an oxide semiconductor and a metal depending on an oxygen content ratio in introduced gas upon depositing an oxide semiconductor film made of indium gallium zinc oxide, zinc tin oxide, or others in an oxide semiconductor thin-film transistor. A contact layer is formed with an oxygen content ratio of 10% or higher in a region from a surface, where the metal and the oxide semiconductor are contacted, down to at least 3 nm deep in depth direction, and a region to be a main channel layer is further formed with an oxygen content ratio of 10% or lower, so that a multilayered structure is formed, and both of ohmic characteristics to the electrode metal and reliability such as the suppression of threshold potential shift are achieved.

Protocols for antitachycardial pacing including biphasic stimulation administered at, or just above, the diastolic depolarization threshold potential; biphasic or conventional stimulation initiated at, or just above, the diastolic depolarization threshold potential, reduced, upon capture, to below threshold; and biphasic or conventional stimulation administered at a level set just below the diastolic depolarization threshold potential. These protocols result in reliable cardiac capture with a lower stimulation level, thereby causing less damage to the heart, extending battery life, causing less pain to the patient and having greater therapeutic effectiveness. In those protocols using biphasic cardiac pacing, a first and second stimulation phase is administered. The first stimulation phase has a predefined polarity, amplitude and duration. The second stimulation phase also has a predefined polarity, amplitude and duration. The two phases are applied sequentially. Contrary to current thought, anodal stimulation is first applied and followed by cathodal stimulation. In this fashion, pulse conduction through the cardiac muscle is improved together with the increase in contractility.

A power-data distribution system including a packet energy transfer (PET) system, a converter, a conductive cable and a fiber optic cable. The PET system transmits discrete packets of digital energy and produces a continuous stream of analog power. The converter reduces the analog power from the first to a second potential, wherein the second potential is lower than a threshold potential. A conductive cable transmits the discrete packets of digital energy from a power source to a load while a fiber optic cable exchanges data between a data source and the target device.

A image display device includes a driving unit that includes a first terminal and a second terminal, and controls current flowing through a light emitting unit based on a potential difference applied between the first terminal and the second terminal. The potential difference is higher than a predetermined drive threshold. The image display device also includes a threshold potential detecting unit that detects the potential difference; a luminance potential supplying unit that changes the potential difference to a value lower than the drive threshold by a luminance potential corresponding to a luminance of the light emitting unit; and a sweep potential supplying unit that controls the driving unit by supplying a sweep potential to the first terminal. The sweep potential is swept in a range between a value lower than the luminance potential and a value higher than the luminance potential.

Measurements of parameters of MOS transistors, also known as MOSFETs, such as threshold potentials, require accurate estimates of source and drain series resistance. In cases where connections to the MOSFET include significant external series resistance, as occurs in probing transistors that are partially fabricated or deprocessed, accurate estimates of external resistances are also required. This invention comprises a method for estimating series resistances of MOSFETs, including resistances associated with connections to the MOSFET, such as probe contacts. This method is applicable to any MOSFET which can be accessed on source, drain, gate and substrate terminals, and does not require other test structures or special connections, such as Kelvin connections.

The pulse generating circuit compares the integrating result of the analogous membrane potential integrating circuit with a predetermined threshold potential in order to generate analogous motion potential pulse. The decoding circuit ingrates the analogous motion potential impulse in order to obtain the analogous motion potential pulse coding signals of output signals consistent with the input signals. The invention simulates the information processing mechanism of the biological neuron and realizes the biological neuron manner with a circuit method.

When the transistor Q3 is OFF, a predetermined potential is supplied to a potential wire Ui such that a switching transistor Q2 becomes ON. This changes a gate potential of a driving transistor Q1 from an ON potential to a threshold potential. Thereafter, the transistor Q2 is turned OFF, with the result that the potential of the potential wire Ui is changed (in cases where the transistor Q1 is a p-type transistor, the potential is decreased). With this, the transistor Q1 allows a current to constantly flows therethrough, irrespective of the threshold potential. This shortens time for setting an output current of the driving TFT for driving a current driving type display element.

Changes of the stray capacitances of a large number of sensing electrodes can be detected simultaneously. Further, even if a stray capacitance changes slightly, an input operation to a sensing electrode can be detected based on elapsed time until the electric potential of the sensing electrode becomes the same as a threshold potential. The stray capacitance of a sensing electrode and a resistor of the sensing electrode form a CR time constant circuit. Charge or discharge of the stray capacitance of the sensing electrode is controlled while a rest time in a predetermined time ratio is set. A stray capacitance that slightly increases in response to an input operation made near a sensing electrode can be detected by detecting the stray capacitance in extended elapsed time until the electric potential of the sensing electrode becomes the same as the threshold potential.

A cortical column emulation circuit includes a capacitor which is coupled at a first end to a source of reference potential by a switch, a current source coupled to the first end of the capacitor for charging the capacitor when the switch is open to develop a capacitor voltage between the first end and the second end of the capacitor; and a comparator which compares the voltage across the capacitor to a threshold potential and generates a pulse signal when the capacitor voltage is greater than the threshold voltage. The pulse signal closes the switch to connect the first end of the capacitor to the source of reference potential. A set of cortical column emulation circuits may be coupled together by an adaptive coupling to form a cortical region emulation circuit. The adaptive coupling circuit weights an input stimulus and a plurality of state vector elements by variable coupling coefficients.

A buffer circuit for providing dynamic threshold control. The buffer circuit includes a pair of input inverters designed with different skewed threshold potential characteristics. The outputs of the skewed inverters are directed to a logic circuit designed to select either the faster or the slower signal received from the two inverters for transmission to passgate devices coupled to the respective inverters. Only one of the passgate devices is enabled to ensure that only one of the output signals from the two inverters is propagated through the buffer. A latch is preferably connected between the logic circuit and the two passgate devices to maintain the states of the inverters and the logic circuit. The circuit can be designed to define the threshold potential at which switching will occur so as to reduce propagation delay or increase it as desired. It is therefore possible using the circuit to increase transmission rates with minimal affect on signal noise.

An internal potential generation circuit of an SDRAM includes a standby VDDS generation circuit which has a relatively low current driving force and which generates an internal power supply potential, and an active VDDS generation circuit which has a relatively high current driving force, which is activated during a period after an external power supply potential is applied until a negative potential reaches a threshold potential, and in an activation period, and which generates the internal power supply potential. Therefore, it is possible to raise the internal power supply potential stably without increasing standby current when the power supply is turned on.

The invention discloses a multilayer eccentric 8-shaped coil for deep site transcranial magnetic stimulation. Multiple layers of coils are arranged; the first layer forms a basic 8-shaped coil, the below coils are symmetrically distributed along the central line of the 8-shaped coil, and thus the magnetic field and a sensing electric field are adjusted. The distance between the central line of each coil layer and the symmetrical axis is determined through an optimization method, and the optimization target is to enable the ratio of the sensing electric field E (z0) generated on the surface of the coil to the deep site sensing electric field E (z) to be the minimal. Each coil layer can be arranged on the same plane or can be crossed for a certain angle. When the deep site achieves a threshold potential, the sensing electric field on the surface of the coil can be in a safe range, and good focusing can be achieved in the deep site. The attenuation index of the sensing electric field along the depth direction of the multilayer eccentric 8-shaped coil is close to or even better than that of an H coil.
