Title: High-resolution coder
Inventor: MITSUCHIERU SHII PURAUAA
IPC: G01D5/16
Filed: 1990-09-18
Abstract: PURPOSE: To obtain a coder with a high resolution by setting the interval between a pair of magnetic poles to a specific value, and setting the reference magnetic flux density of a pair of magnetic poles to a specific value, and relating the value to the range of the value of the interval between magnetic poles. CONSTITUTION: The coder 20 gives relatively a large number of magnetic pole pairs 23 that are accurately positioned at a member that can be magnetized for satisfying request conditions for high-resolution applications. Also, each total number of magnetic pole pairs 23 for one coder 20 have an optimum magnetic flux density related to the magnetic pole pairs 23. The combination of the magnetic flux density - magnetic pole pairs has a new range of values for a specific application such as a bearing. A reference magnetic flux density Fr is obtained by an equation, where K1=158-1,056 Gauss/cm<2> , K2=158-1,056 Gauss/cm<2> , K3=158-1,056 Gauss/cm<2> , X = a magnetic pole interval between adjacent magnetic pole pairs, Fr = a reference magnetic flux density range at centigrade +20 deg.C when K1 , K2 , and K3 are equal.  Also, the equation can be applied to a gap of 0.91mm between the outer surface of the coder 20 and the sensing part of a sensor.

IPC: G02F1/133
Filed: 1992-08-25
Abstract: PURPOSE:To provide the driving method which makes a gradation display of ferroelectric liquid crystal element by a matrix driving system. CONSTITUTION:Write pulses (A) in composite signal-waveforms S-I1-I4 of a scanning signal waveform S and information signal waveforms I1I4 consist of a 1st pulse (B) which is not inverted in state by itself and a 2nd pulse (C) and the state inversion is caused by varying the width of the 2nd pulse which has a higher crest value than the 1st pulse to make a half-tone display. Therefore, the time for one scan can be made shorter than that of a driving method which uses rectangular pulses and the dynamic range of the pulse width of the information signals is widened to excellently make the half-tone display.

Filed: 1997-08-29
Abstract: PROBLEM TO BE SOLVED: To avoid the resonance of an injection period with fuel pressure fluctuation and reduce the fluctuation of fuel pressure by varying the injection period of an injector when the revolution speed of an engine enters the range of a resonance region during the operation in the specified injection period of the injector. SOLUTION: Data indicating the relation between the injection period of an injector and a resonance region (the revolution speed of an engine), or data of the injection period which should be varied in the case of entering the resonance region in the injection period of the injector is experimentally obtained, and the data obtained is stored in an electronic control unit. During the operation of the engine, the ECU judges whether the revolution speed of the engine is in the resonance region or not (S1). This judgement is conducted by comparing the present injection period of the injector with the data indicating the relation between the resonance region in the injection period and the resonance region. If the judgement is YES, the injection period of the injector is varied about 1/2 the injection period (S2) to avoid the generation of the resonance.
