Title: Operating circuit device for soil discharge plate
Inventor: AKIMOTO TAKAO
IPC: E02F3/85
Filed: 1986-10-23
Abstract: PURPOSE:To make easier the manufacture of an operating circuit device by providing an operating valve to extend or contract a tilt-pitch cylinder, switching valves to be operated (for only one) during tilting operation but to be operated (for both) during pitch operation, and a dividing and collecting valve to equally divide pressure oil. CONSTITUTION:When an operating valve 1 is operated to the extending side (a) of cylinder, pressure oil from a pump 2 enters the bottom side of a tilt-pitch cylinder 8 through the port 5a of a dividing and collecting valve 5, permitting a soil discharge plate to make a tilting action. When a switch 8 is pushed, solenoids 15 and 16 are excited, a pipeline 13 is closed by a switch valve 14, and a switch valve 17 is opened. When the operating valve 1 is operated to the side (a), pressure oil enters the valve 5 and divided equally into two flows, and the cylinders 8 and 12 are extended with equal speeds. The soil discharge plate performs a pitch front-tilting action. When the valve 1 is operated to the side (b), the soil discharge plate makes a pitch back-tilting action. The left and right-handed cylinder diameters can thus be used in common.

Title: Impedance conversion circuit
Inventor: ITO TAKASHI
IPC: H03H11/40
Filed: 1989-09-27
Abstract: PURPOSE:To make a voltage at an input terminal constant by providing a 1st terminal receiving a reference voltage and a 2nd terminal receiving an external current so as to decide an output current with respect to a signal from a differential amplifier means and outputting its output current to an external output terminal. CONSTITUTION:A reference voltage VR being voltage division of a power supply voltage by resistors 20, 21 to a 1st terminal 11, of a differential amplifier means 17. Moreover, a voltage V1 with respect to the reference voltage VR is given to a 2nd terminal 10'. Then a signal corresponding to the difference between the reference voltage VR at the 1st terminal and the voltage V1 at the 2nd terminal is outputted as an output signal of the differential amplifier means 17 by a transistor(TR) 15. Then a 1st current output means 27 receives an output signal from the differential amplifier means 17 and outputs a current I1 to the 2nd terminal so that the voltage V1 at the terminal 2 is identical to the reference voltage VR. Thus, the input signal voltage V1 is equal to the reference voltage VR and kept constant.

Title: Optical scanner
Inventor: TAKI KAZUYA
IPC: G02B5/32
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To provide an optical scanner capable of attaining very accurate optical scanning as an optical scanner using a hologram. SOLUTION: A hologram disk 5 is produced to be a curved surface where its incident surface 25 and an exiting surface 26 have curvature. The disk 5 is formed to be warped upward, and the direction of the curvature center of the warpage is reverse to the gravity direction at the time of assembling. Therefore, when the disk 5 is supported at its center part, the disk 5 is bent downward, so that the upward warpage in production is negated. As a result, the fluctuation of the diffraction angle of the diffracted laser beam 22 caused by deflection becomes remarkably small and the very accurate and stable optical scanning is attained.

Title: Shift lever device
Inventor: MORIKAWA MINORU
IPC: G05G1/04
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To provide a shift lever device making a shift position confirmable also by tactile sensation obtained at the time of operating a shift lever. SOLUTION: In a shift lever device 10, a slant face part 42 is formed at a click groove 40, and a gate recessed part 36 is formed at a housing 30. A click pin 26 can thereby be moved from a neutral range position into the other direction different from a shift operating direction, and a shift lever 12 can be moved in association. The position of the shift lever 12 can therefore be confirmed by tactile sensation obtained in the case of operating the shift lever 12 into the gate recessed part 36. In the case of moving the click pin 26 in the other direction, the click pin 26 is restored by the energiging force of a coil spring 28 into the neutral range position of the click groove 40 from the slant face part 42. Operability of the shift lever 12 in normal shift operation is not therefore impaired.

Title: Solid-state image pickup device
Inventor: YONEMOTO KAZUYA
IPC: H04N5/335
Filed: 1986-10-23
Abstract: PURPOSE:To obtain a reproducing image with uniform contrast, by constituting a device so that a prescribed voltage is impressed on a conductive type semiconductor substrate in a horizontal blanking period. CONSTITUTION:A voltage VH, for example, 30(V) is impressed on an N-type silicon substrate 4 in the horizontal blanking period, and signal charge accumulated in a signal charge accumulating area 6 is swept to the N-type silicon substrate 4. In other words, the voltage 30V is impressed on the N-type silicon substrate 4 at every horizontal blanking period until just before exposure is started after reading by a read pulse P1, and the signal charge accumulated in the signal charge accumulating area 6 is swept, and in an exposure time=t2, the signal charge is accumulated by setting the voltage at 10V to be impressed on the N-type silicon substrate 4. Thus, since the period where the voltage VH, for example, 30V is impressed on the N-type silicon substrate 4 is set in the horizontal blanking period, no influence is given on the reproducing image even when the buffer amplifier of an output part, etc., receives modulation due to the varying of the voltage impressed on the N-type silicon substrate, and the reproducing image with the uniform contrast can be obtained.
