Title: Reflection type image display device
Inventor: TETSU HIDEO
IPC: H04N5/74
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To obtain a high reflection factor and prevent incident light from entering a substrate to cause deterioration in picture quality. SOLUTION: A light shield layer 51 is interposed in insulator layers 4a and 4b on condition that at least the gap area between reflecting electrode layers 8a and the overlap area of non-metal constitution areas of active element circuits 2 and 3 are included in a plan viewed from the incidence direction of read light; and the surface of an insulator layer 4b is flattened into an optical mirror surface state and then a reflecting electrode 8a is formed. The generation of photoconduction can be prevented since there is no area where the read light enters the substrate 1 directly and a reflection factor of >=90% is obtained since the surface of the reflecting electrode layer 8a has extremely high flatness.  Further, reflection preventive films 52 and 53 are formed on the opposite surface sides of the reflecting electrode layer 8a and light shield layer 51, so the incidence of light reflected repeatedly between the layers can be prevented.

Title: Lift-controlling apparatus
Inventor: IIDA SATOSHI
IPC: A01B63/10
Filed: 1990-07-17
Abstract: PURPOSE:To lower a working apparatus at a high speed in an engine-stopped state by restraining the deceleration motion of a deceleration controlling means based on a detection action of a detection means to detect the stopped state of an engine of a mobile machine body connected to a ground-working apparatus. CONSTITUTION:When a ground-working apparatus is lowered from a position near the lower limit to a prescribed setting position in the lowering work, the current supplied to a solenoid-operated proportional control valve is decreased with a deceleration controlling means A. The working speed of a hydraulic actuator to lift the ground-working apparatus is set by the proportional control valve based on the supplied current level. When a detection means S detects that the engine of a mobile machine body connected to the ground- working apparatus is in stopped state, the deceleration action of the deceleration controlling means A is restrained with a restraining means B. A driving current of the maximum duty ratio is supplied to the control valve in the stopped state of the engine and the working apparatus is quickly lowered over the whole stroke until the apparatus reaches the preset tilling depth.

Abstract: PURPOSE:To meet a demand for a low noise and provide a packaged semiconductor laser drive by monitoring a gallium arsenide integrated circuit convoluted by a high frequency current as well as a beam outgoing in the froward direction of a semiconductor laser and causing a silicon I.C. having a function of negative feedback to turn into an integrated hybrid one. CONSTITUTION:When a semiconductor laser 8 operates in a constant light output state, a signal generated out of a built-in PIN photodiode 13 is fed to an external (constant light output drive) circuit through a through type 14 and a DC current that flows in the semiconductor laser 8 is controlled so that its signal can be maintained at a constant rate. A high-frequency current fed from a gallium arsenide integrated circuit for convoluting the high frequency is convoluted to the DC current through a load coil 6 and a coupling capacitor 7. Accordingly, the semiconductor laser makes oscillation having a stable noise level. Yet, a portion of the beam outgoing in the forward direction of the semiconductor laser is taken out and is fed to the external PIN photodiode 9 and then, the signal is amplified and a noise decreases by causing the semiconductor laser 8 to have a negative feedback function.

Title: Device for controlling quantity of light
Inventor: TAGUCHI TOYOKI
IPC: G02F1/01
Filed: 1983-10-11
Abstract: PURPOSE:To increase the rate of improvement and to stabilize control operation by adding an integration circuit into a control circuit and setting the initial value of the integration circuit to zero when the gain deviates. CONSTITUTION:If it is assumed that the initial value in the stage of starting control is at the point (e) the output of an integration circuit 13 has certain initial value and since the control gain is high, said output cannot be brought under control and rises to much higher potential. The output P0 of a comparator 15 rises to a high level at the moment when the potential exceeds the upper reference value VR<+> of the comparator 15. A switch 17 is then closed and the output of a differentiation circuit 13 attains 0 volts. The output of the circuit 13 rises gradually in potential upon lapse of the time TS, thus pulling control in. Once the control is pulled in, a stable control characteristic for the quantity of light is obtd. with a high rate of improvement as the control gain is high. The rate of improvement is thus increased and the control operation is stabilized.

IPC: B60T8/172
Filed: 1993-07-30
Abstract: PURPOSE:To estimate a mu of road surface accurately even if anti-skid brake control is started on a low mu road by calculating a friction coefficient of a road surface based on the differential value of an average wheel speed or that of a selected rear wheel speed. CONSTITUTION:An ABS controller 26 reads the wheel speeds VFL, VFR, VRL, and VRR of wheels stored temporarily in a memory. Next, based on these wheel speeds, an average front wheel speed VFA and a selected rear wheel speed VRS are calculated. Then it is judged whether or not the average front wheel speed VFA is over the selected rear wheel speed VRS, i.e., VFA>=VRS. When the judgment result here is true, a mu of road surface is calculated based on the differential value of the average front wheel speed VFA, i.e., its degree of deceleration. On the other hand, when the judgment result is false, the muof road surface is calculated based on the differential value of the selected rear wheel speed VRS, i.e., its degree of deceleration.
