A mass spectrometer is disclosed wherein ions having a particular desired charge state are selected by operating an ion mobility spectrometer in combination with a quadrupole mass filter. Precursor ions are fragmented or reacted to form product ions in a collision cell ion trap and sent back upstream to an upstream ion trap. The fragment or product ions are then passed through the ion mobility spectrometer wherein they become temporally separated according to their ion mobility. Fragment or product ions are then re-trapped in the collision cell ion trap before being released therefrom in packets. A pusher electrode of a time of flight mass analyzer is energized a predetermined period of time after a packet of ions is released from the collision cell ion trap. Accordingly, it is possible to select multiply charged precursor ions from a background of singly charged ions, fragment them, and mass analyze the fragment ions with a near 100% duty cycle across the whole mass range.

A radio transmitter / receiver having a QoS control unit for outputting the transmission data in order taking the quality of service (QoS) into consideration. In the case where the information transmission rate for a radio section is not lower than a threshold value, the QoS control operation of the transmission data is omitted, and the transmission data are output in the order of input. In the case where the information transmission rate for the radio section is lower than the threshold value, on the other hand, the QoS control mode is switched in accordance with the information transmission rate for the radio section.

In addition to two-stage CMOS inverters inverting and amplifying the input signal, a rising edge detector detects the rising edge of the input signal, and outputs a rising edge detection signal having a pulse width corresponding to ambient temperature, a PMOS drives the output node to the power supply potential according to the rising edge detection signal, a falling edge detector detects the falling edge of the input signal and outputs a falling edge detection signal having a pulse width corresponding to ambient temperature, and an NMOS drives the output node to ground potential according to the falling edge detection signal. When ambient temperature rises, and delay time of the inverters are thereby increased, pulse widths of the rising and falling edge detection signals are increased. The additional driving restrains delay time variation in a driving circuit due to ambient temperature change.

The Objective of the present invention is to provide a delay unit for door with a door closer, which is capable of automatically closing the door after the elapse of a certain time since the door was opened and can be installed in case that the door closer is embedded inside the building and thereby being not exposed.The objective is solved by providing a delay unit 5 for door with a door closer comprising: a first sensor for detecting the door 2 opened to the first angle A, a lock unit 7 for electrically lock / unlock of the rotation of the rotation axis 3 of the door 2, a timer, a first sensor, and a control means, with which the first sensor, lock unit 7, and timer is connected, for controlling the lock unit 7 based on the signals from the first sensor and timer.

In a level shifter, in the case where the amplitude voltage of an input signal (i.e., a first power voltage VDDL) input to an input terminal is changed to be higher and the amplitude voltage of an output signal (i.e., a second power voltage VDDH) output from an output terminal is changed to be lower, a fall delay time of the signal output from the output terminal tends to be longer than a rise delay time of the signal. However, an inverted input signal obtained by an inverter is input to a level shifting unit and also to the gate of an N-type transistor, and therefore, the N-type transistor is turned on at the fall of the input signal input to the input terminal, so as to supply a current based on the second power voltage VDDH to an output node of the level shifting unit for assisting the shift into H level performed in the level shifting unit. Accordingly, even when at least one of the amplitude voltage of the input signal and the amplitude voltage of the output signal is changed, balance between the fall delay time characteristic and the rise delay time characteristic of the output signal can be satisfactorily kept.

A data output driver and a semiconductor memory device having the same are disclosed. This data output driver includes: a rising transition slope adjuster including a plurality of first delay units cascade-connected to each other and receiving data and generating delayed data, each of the first delay units having a delay time which varies in response to a first control signal; a falling transition slope adjuster including a plurality of second delay units cascade-connected to each other and receiving inverted data and generating delayed inverted data, each of the second delay units having a delay time which varies in response to a second control signal; a pull-up driver including a plurality of pull-up circuits, the driving capabilities of the pull-up circuits being adjustable in response to a third control signal, each pull-up circuit pulling-up output data in response to each of the data and the delayed data; and a pull-down driver including a plurality of pull-down circuits, the driving capabilities of the pull-down circuits being adjustable in response to a fourth control signal, each pull-down circuit pulling-down output data in response to each of the inverted data and the delayed inverted data, wherein the first control signal varies in response to the third control signal, and wherein the second control signal varies in response to the fourth control signal. Accordingly, the rising and falling transition slopes of the output data can be constant even when the driving capability is varied, so that output data having desired characteristics can be produced.
