Title: Liquid crystal display device
Inventor: KUWABARA KAZUHIRO
IPC: G02F1/133
Filed: 1990-07-09
Abstract: PURPOSE:To obtain the liquid crystal display device with good display quality by turning off TFTs for respective picture elements except when image information is supplied to the TFT themselves. CONSTITUTION:Respective scanning lines 16(1) - 16(i) are divided into (n) picture element TFT group selection lines 16(x)-1 - 16(x)-n, TFT.Trxy for picture elements which are connected to the same rows on a display part 65 are divided into (m) groups of (m) TFT.TRs, and the gate electrodes of the Trxy in the same groups are connected in common by TFT group selection lines 16(x)-1 - 16(x)-n. Then when image information is supplied to the Trxy of the respective rows, a picture element TFT group selecting means turns on the TFT group selection lines 16(x)-1 - 16(x)-n in order to supply the image information to the TFTs in the respective groups and the supply of the image information to the respective rows is carried out repeatedly to all the rows. Therefore, each picture element TFT is placed in the OFF state except when the image information is supplied to the TFT, so an amount of charge corresponding to the image information is never discharged through the picture element TFTs and cross resistances. Consequently, the display quality is improved.

Filed: 1993-07-22
Abstract: PURPOSE:To prevent a main transistor from being damaged when an overcurrent flows to the main transistor by a method wherein a resistance which is connected to an emitter for the main transistor and a capacitor which is connected to an emitter for a photocoupler are connected to a base for a control transistor. CONSTITUTION:By the collector current, of a photocoupler P, which is changed according to an output voltage, the charging time of a capacitor C is changed, the ON-time of a control transistor Tr2 is controlled on the basis of the voltage of the capacitor C, the base current of a main transistor Tr1 is controlled, and the output voltage is changed into a constant voltage. On the other hand, when an output current becomes excessive, the voltage drop of a resistance R become large, the control transistor Tr2 is turned on, the base current of the main transistor Tr1 is limited, and the generation of an overcurrent is prevented. Thereby, the number of components is reduced, and the circuit constitution can be made simple.

Filed: 1998-06-12
Abstract: PROBLEM TO BE SOLVED: To reduce the consumption of a working fluid caused by pulsation pressure absorption by regulating the deflection amount in the opposite direction to a liquid pressure chamber of a diaphragm. SOLUTION: A diaphragm 24 is supported by a supporting point member 31 and a regulating means 31A. At this time, the supporting point when the diaphragm 24 is deflected is four points, A, B, C and D, so that the areas of the diaphragm allowed to be deflected are three areas, between A and B, B and C, and C and D. That is, the absorbing action for pulsation pressure is performed by simultaneously or independently the respective divided areas of the diaphragm 24. Accordingly, as a whole, the deflection amount to the air chamber 25 side of the diaphragm 24 can be regulated to be larger than before. The regulation is performed especially for a large pulsation pressure component giving an influence on pedal feeding or the like among the pulsation pressure components so that at least only the pulsation pressure component may be absorbed.  In this case, the deflection amount can be adjusted by varying the inside diameter of the regulating means 31A.
