Title: Controller of four-wheel steering vehicle
Inventor: TAKAHASHI TSUTOMU
IPC: F02D29/02
Filed: 1991-10-31
Abstract: PURPOSE:To secure both driveability and safety according to the steering angle of rear wheels which is fixed when a motor-driven rear wheel steering gear fails. CONSTITUTION:Engine outputs are controlled by opening or closing a throttle valve 34 using a motor-driven throttle valve unit 30 in response to accelerator control, and if front wheels are steered during turning, rear wheels 8 are also steered by a motor-driven rear wheel steering gear 1 and four-wheel steering control is performed. If the motor-driven rear wheel steering gear 1 fails, the rear wheels 8 are fixed at the rear wheel steering angle of the time of failure; in this case, if the rear wheel steering angle is small and the vehicle is in a relatively stable state, limiting control of throttle opening is done by a small amount to secure driveability, whereas if the rear wheel steering angle is large and the vehicle is in an unstable state, limiting control of the throttle opening is done by a large amount so as to secure stability.

Title: Servo type accelerometer
Inventor: ITO AKIO
IPC: G01P15/13
Filed: 1986-12-27
Abstract: PURPOSE:To obtain detection characteristics which are stable to temperature variation by providing plural light reception parts divisionally on one element. CONSTITUTION:Light reception parts 20a and 20b of a light receiving element 20 convert light from a light emitting element 21 photoelectrically and the output voltages of the light reception parts 20a and 20b are amplified differentially by an operational amplifier 32 constituting a differential amplifier with resistances R2 and R3 and thus compared to generate a detection signal here. If positive acceleration is applied as shown by an arrow A1 (or A2), a light shield pin 16 deviates as shown by an arrow B1 (or B2) according to the extent of the acceleration and the quantity of light reception of the light reception part 20b (or 20a) increases, so that a detection signal having a value corresponding to the deviation quantity of the light shield pin 16 is generated. Thus, the signal light receiving element 20 which is divided into two light reception parts 20a and 20b is used, so detection characteristics for acceleration which are stable to temperature variation are obtained.

Abstract: PURPOSE:To obtain a thick SiO2 film at a low temperature in a short time by oxidizing an Si3N4 film by a lamp annealing method wherein the Si3N4 film is oxidized in an atmosphere containing ozone. CONSTITUTION:When a substrate 2 surface is heated by a lamp 4, while ozone is introduced in a reaction vessel 1, an Si3N4 film 6 formed on the substrate surface is oxidized, and the surface is gradually turned into an SiO2 film 7. The forming speed of the SiO2 film is more than or equal to two times the speed at 1100 deg.C, and more than or equal to three times the speed at 1150 deg.C, as compared with the case where ozone is not contained. The heat treatment time required for growing an SiO2 film having a specified thickness can be reduced by a factor of 3. Therefore by a lamp annealing method, the Si3N4 film is oxidized at comparatively low temperature and in a comparatively short time, and a thick SiO2 film can be formed.

Filed: 1997-11-17
Abstract: PROBLEM TO BE SOLVED: To efficiently attenuate vibration due to resonance by forming a gap part in an insulating member disposed on a base, disposing a strip member and disposing a soft and adhesive damper member to surround this strip member. SOLUTION: A movable member 2 and a fixed member 16 are connected up via linear elastic supporting members 3A-3D, and the elastic supporting member 3A is composed of a metal wire consisting of phosphor bronze having a diameter of 0.1-0.2mm and a damper member consisting of butyle rubber formed integrally with the outer periphery of the metal wire.

Consequently, undesired resonance can be prevented, and hence damping operation can effectively be performed. In this case, the damper member has a large diameter part and a small diameter part, and their diameters are 1.3mm and 0.6mm respectively.

As initial conditions, the lens magnification M is set in a magnification controller 20, the X-axis feeding speed S is set in a feed controller 18, and the storage time T1 of the sensor 19 is set in a CCD drive controller 22. The entire LCD surface is measured by the sensor 19, the lens magnification M2 is calculated, and the number of measurements N2 of one pixel of the X-axis direction is calculated. When the calculated magnification M2 and the times N2 have fractions of a decimal point, the fraction is raised or lowered as a correction value of an integer multiplication, the speed S is made invariable, and the time T for realizing the times N2 is obtained. The obtained magnification M and the time T are newly set, and the measurement and correction are repeated to eliminate a moire.
