Inventor: YOSHIMOTO YUJI
IPC: G02F1/133
Filed: 1987-03-17
Abstract: PURPOSE:To improve the opening rate of a color display image by alternately disposing color filters of respective colors above and below respective lower electrodes. CONSTITUTION:The plural upper, lower electrodes 3, 4 are formed in a band shape respectively orthogonally with each other on the opposite surfaces of light transmittable upper and lower substrates 1, 2 which are disposed to face each other.

Title: Steering control device
Inventor: KAWAGUCHI YUTAKA
IPC: B62D119/00
Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To control a hysteresis width in a steering angle-steering reaction characteristic by controlling a phase of steering reaction acting on a steering wheel by controlling driving of an actuator for imparting driving force to a steering system. SOLUTION: A vehicle speed, a steering angle θ, lateral acceleration, a load current value Ir and steering torque Mt detected by respective sensors 55 to 59 are read in. The whole steering load acting on a steering wheel 50 is arithmetically operated to be set as the total load. A control current value to an assist motor 54 is set on the basis of this total load and the vehicle speed. Then, a target current value Im to the assist motor 54 is set by using the lateral acceleration to adjust a phase of steering reaction besides the control current value. The target current value Im is outputted to a driving circuit 61, and the driving circuit 61 controls a driving current so that the target current value Im is supplied to the assist motor 54.  Thus, the phase of the steering reaction to the steering angle θ is advanced according to the lateral acceleration to restrain reduction in a hysteresis width.

Title: Phase difference measuring device
Inventor: NAKAO SHIYUNJI
IPC: G01R25/00
Filed: 1979-05-18
Abstract: PURPOSE: To measure a phse difference on the basis of signals input into a phase difference measuring device from a plurality of points in a short time, by employing a simple processing circuit for measuring a phase difference between two arbitrary points.  
     CONSTITUTION: Detected signals from displacement detectors 1, 2 provided in two points among many points on a structure are amplified by amplifiers 3, 4 to be applied to filters 5, 6. Signals x 1 , x 2  from for filters 5, 6 are applied to an adder 7 and then to a rectifier 8. Output signals from the rectifier 8 are separated into positive and negative signals, which are applied to integrators 9, 10, respectively, to determine the areas represented thereby. The sum total of the areas is calculated by an adder 11. On the basis of this value, variations in phase difference are determined in a phase difference checking means 12. A measured signal in this method contains a large amount of frequency component, and a superior component has a greater amplitude. Accordingly, when an increase and decrease in an absolute value of the sum of two signals are traced, variations in phase difference can be determined or information as to whether an oscillation mode is being changed or not can be obtained. A phase difference measuring device according to this invention has been achieved on the basis of the above technique.

This adhesive is put within a bulb base by the use of a cement filling machine. This base filled with adhesive is fitted to the two ends of a fluorescent lamp body by conventional means and put into a high frequency coil, and a high frequency electric field is impressed. The alcohol in the adhesive gains bi-polarity, which is depolarilized according to the high frequency electric field to cause heat emission, and the adhesive is heated by this heat to approx. 100 deg.C. Consequently the phenol resin is thermohardened, and at the same time, alcohol evaporates, and the heat emission is stopped by runoff of the alcohol and contained water ground when thermohardening is completed.

Title: Driving method of bistable semiconductor laser
Inventor: MACHIDA TOYOTOSHI
IPC: H01S5/042
Filed: 1990-03-13
Abstract: PURPOSE:To enable a bistable semiconductor laser to be reset in a short time and to lessen a reset pulse in amplitude by a method wherein the semiconductor laser is reset by inputting a reset pulse when the output laser ray becomes minimal in intensity a certain time after a set pulse is inputted. CONSTITUTION:A set pulse is inputted into a bistable semiconductor laser to drive, the change of the laser in optical output Pout is measured to obtain the time Tmin when the optical output Pout becomes minimal in intensity first after the set pulse is inputted. Then, a reset pulse of voltage V1 is applied to a tandem electrode 21 when the time Tmin elapses after the set pulse is inputted. When an active layer 16 becomes minimal in gain due to the relaxation oscillation, a reset pulse is inputted. Therefore, the optical output Pout of the reset bistable semiconductor laser decreases sharply. By this setup, a time required to reset the semiconductor laser can be reduced to 1/100 of that required in a conventional method in which a reset pulse is inputted after the relaxation oscillation due to a set pulse ceases. Moreover, the amplitude of the reset pulse can be made half the maximum amplitude.
