Patent JP-H07154982-A (JP)
Title: Ultrasonic actuator
Inventor: TOBE MICHIHIRO
IPC: H01L41/09
Filed: 1993-11-26
Abstract: PURPOSE:To miniaturize a stator by a method wherein vibration-suppressing materials are installed at one end or both ends p' of an elastic body for the stator. CONSTITUTION:A stator 10A is constituted of an elastic body 11, of a piezoelectric body 12 and of vibration-suppressing materials 14 which are installed at end parts of the stator 10A. In this constitution, an AC electric field is applied to the piezoelectric body 12, and traveling waves are generated in the elastic body 11. Then, it is possible to restrain the traveling waves from being generated at the edge of the elastic body 11 thanks to the vibration-suppressing materials 14. As a result, it is possible to restrain standing waves from being generated. In this case, vibration energy is consumed in the form of heat or the like generated due to internal friction caused by the deformation of the vibration-suppressing materials 14. Thereby, vibrations can be absorbed by the stator 10A itself, and the stator 10A can be miniaturized.

Abstract: PURPOSE:To shorten the braking distance by providing a hydraulic pressure generating device applying the braking hydraulic pressure in response to the brake operating force to the first brake cylinder and a solenoid hydraulic pressure control device applying the braking hydraulic pressure controlled according to the lock occurrence state to the second brake cylinder. CONSTITUTION:A front wheel cylinder 18 is connected to a master cylinder 14 generating the first braking hydraulic pressure with the magnitude nearly proportional to the operating force of a brake pedal 10 via a main liquid passage 20.

Title: Decoder
Inventor: MORIMOTO MINORU
IPC: H03M7/00
Filed: 1989-12-12
Abstract: PURPOSE:To avoid the abnormality of an output control signal through a simple circuit configuration by constituting the logic circuit of a preceding stage of plural NAND gates, and constituting the logic circuit of a following stage of plural NOR gates, and using the rise characteristic of each gate. CONSTITUTION:The output control signals Y0 to Y7 are outputted respectively from the NOR gates 8 to 15 according to the bit pattern of each input signal C, B, A. In this case, the leading time of the NAND gates 4 to 7 that their outputs vary from 'L' level to 'H' level is short, and the trailing time of them that their outputs vary from 'H' level to 'L' level is long. As for the NOR gates 8 to 15 of the following stage, the leading time and the trailing time become contrary to those above mentioned. Accordingly, always after the outputs of the NAND gates 4 to 7 of the preceding stage rise up to 'H' level, the outputs of the NOR gates 8 to 15 of the following stage rise up to 'H' level. Accordingly, two or more output control signals Y0 to Y7 never become 'H' level at a time, or an unnecessary pulse is never generated in Y0 to Y7.

Light is absorbed by a coloring matter bringing a dark state when the voltage is no impressed. The light is reflected by the aluminum thin film on the rear surface and the bright state is brought about when the liquid crystal layer is made transparent by the voltage impression. A need for making correction according to the level of the voltages impressed to the adjacent pixels arises in the case of making response with the sufficient voltage in the regions exclusive of the pixels. The gradation level corrected by the numerical value obtd. by multiplying the gradation level of the adjacent pixel by a negative constant is sent on the basis of the gradation signal of the certain pixel. The max. value of the driving voltage is set at the level at which the region exclusive of the pixels responds.
