The invention relates to an operation method of an optical displacement detection device. The method comprises the following steps of: capturing a plurality of images; obtaining a displacement amount according to the plurality of images; obtaining characteristic value changes of the plurality of images; and suppressively outputting the displacement amount when the characteristic value changes accord with preset rules. The invention also provides an optical displacement detection device.

A semiconductor device employs two electric fuses (31, 32) connected in parallel to each other. First terminals of the electric fuses (31, 32) are connected to a junction of first and second P-channel transistors (21, 22), which are connected in series between a high potential application line (111) and a ground, and connected to a third P-channel transistor (23). Second terminals of the electric fuses (31, 32) are connected to a low potential application line (121). When an extra-high voltage is applied between the first and second terminals of the electric fuses (31, 32), a breakdown connection is produced in at least one of the electric fuses (31, 32). Thus, 1-bit information is written into the semiconductor device.

The aim of the invention is to suppress the peak current of a display drive circuit having a blank control function. Pieces of display data (D1-Dn) are latched by a data latch (11) and provided to AND gates (121-12n) to which gate control is performed by a blank signal / BLK. Output signals of the AND gates (121-12n) are provided to drivers (141-14n) after being delayed by delay circuits (131-13n) having mutually different delay time (tau 1-tau n) and supplied to a display unit as drive signals Q1-Qn. Since timing of change of signals S1-Sn provided to each of the drivers 141-14n is distributed by the delay circuits (131-13n), timing of current i 1-i n flowing to the drivers (141-14n) is also distributed and the total sum Sigma 1 of the current i 1-i n shows gently temporal change and a peak current value decreases.

In a core substrate 30, a ground through hole 36E and a power through hole 36P are disposed in the grid formation, so that electromotive force induced in X direction and Y direction cancel out each other. As a result, even if mutual inductance is reduced and a high frequency IC chip is loaded, electric characteristic and reliability can be improved without generating malfunction or error.

An apparatus for discharging tissue that is folded several times and stacked is provided. The apparatus includes a cartridge that holds stacked tissue and has a through hole at one end, and a holding member that is disposed adjacent to the through hole of the cartridge and pivots on an axis to grasp and remove tissues one at a time from the top of the stack through an arm. The inventive apparatus allows a user to easily replace tissue and check the amount of tissue used and the amount left to use through visual means. The apparatus virtually eliminates the problem of tissue dispensing failure, and has increased precision and reliability and reduced dispensing time over conventional apparatuses.

The invention discloses a plastic pipe mould cooling device capable of carrying out continuous circulating operation. The plastic pipe mould cooling device capable of carrying out continuous circulating operation comprises at least two plastic pipe moulds, wherein each plastic pipe mould comprises at least two mould bodies which carry out circulating operation along annular rails, the mould bodies on the plastic pipe moulds are correspondingly arranged in a one-to-one mode, a cooling water cavity is arranged inside each mould body, and each cooling water cavity is communicated with a cooling water movement pipeline. Due to the fact that water inlets and water outlets of the plastic pipe moulds are connected with cooling water circulating pipelines in a one-to-one mode through water feeding pipelines and water discharging pipelines, a cooling water circulating channel is a totally-closed pipeline, leakage cannot easily happen, and the fault rate is low; due to the fact that operation of the cooling water feeding pipelines, the cooling water discharging pipelines and operation of rotation pipeline converters are in continuous same-direction movement, movement impact is low, and the service life is long; due to the fact that a drive system is in gear drive and chain wheel and chain drive, the drive ratio is constant, the same power source is used by the drive system and is used for drive of the plastic pipe moulds, and elimination of malfunctions is ensured. The plastic pipe mould cooling device capable of carrying out continuous circulating operation has the advantages of being high in cooling efficiency, stable and reliable in operation, and capable of carrying out high-speed and high-efficiency operation.
