Title: Powder measuring apparatus
Inventor: KUROSAWA NOBUO
IPC: G01F11/34
Filed: 1988-09-03
Abstract: PURPOSE:To measure powder promptly and correctly by discharging a predetermined amount of said powder from an output of a second funnel every time first and second valves are simultaneously driven in a vertical direction by a driving member. CONSTITUTION:When a driving member 5 is pressed down and a second funnel 2 is blocked by a second valve 4, the powder moves from a first funnel 1 to the second funnel 2 because a first valve 3 is opened. The powder is filled in the funnel 2. The capacity of the funnel 2 is set to be a desired measuring value. Then, when the member 5 is pressed up, the valve 3 is closed, whereas the valve 4 is opened. Therefore, the powder filled in the funnel 2 falls downward from the funnel 2. Since the powder cannot fall from the side of the funnel 1 at this time because the valve 3 is closed, a predetermined amount of the powder equal to the capacity of the funnel 2 is discharged. Thus, the powder can be promptly and correctly measured.

Filed: 1991-08-31
Abstract: PURPOSE:To increase response of an engine speed control to a target speed command value by an amount of accelerator control. CONSTITUTION:A throttle valve 3 of an engine 1 is opened and closed by a stepping motor 5. An accelerator opening is detected by an accelerator sensor 10, and ignition signals for actual rotational speed is detected by a distributor 11. Then a controller 14 determines a target opening of the throttle valve 3 based on the deviation between a target rotational speed for the accelerator opening and an actual rotational speed detected by the distributor 11, and drives the stepping motor 5 by PID control so that the target opening can be attained. Also the controller 14 drives the stepping motor 5 by schedule control to open the throttle valve 3 forcibly at a specified opening without using PID control when the accelerator opening is varied beyond a specified value for each unit of time. Thus the throttle valve 3 can be opened and closed immediately.

Title: Semiconductor memory circuit
Inventor: YAMAGUCHI DAISUKE
IPC: G11C7/00
Filed: 1986-09-20
Abstract: PURPOSE:To prevent a malfunction caused by a noise, hazard, etc. by generating a clock signal for controlling the register of PROM in the internal part of LSI so that a clock signal from an external part is eliminated. CONSTITUTION:Output signals a0 and b0 are inputted to a decoder driver DD and a multiplexer MPX and a signal c0 is inputted to an OR circuit. In the OR circuit, when the first H level of either of c0-cn-1 is inputted, the output comes to be the H level and maintained until all inputs go to an L level. Consequently, when the output of the OR circuit is used as a clock signal CLK, the timing shift of an address input can be removed. Namely, the clock signal CLK is inputted to a register SR. When the clock signal CLK is the H level, the data are transferred from a master FF to a slave FF. The output data latched to the slave FF are outputted through an output buffer OB. Thus, a control clock signal for driving a register is generated internally based on the address input and can be supplied to the register.

Title: Distance detecting device
Inventor: TANIGUCHI TOSHIHIKO
IPC: G01C3/00
Filed: 1988-09-02
Abstract: PURPOSE:To correct the deviation of a set position of a photosensor in an easy manner by controlling a potential at one terminal of an integrating capacitor, when first and second integrating operations are not executed, to be a reference potential which is a standard for said first and second integrating operations. CONSTITUTION:A switch 10 is so adapted as to be turned on only for a predetermined time T1 during the projection of light. A first integrating operation is carried out during the time T1 by a first integrating current II1 in an integrating capacitor 9. After the time T1 has passed, when switches 10, 13 and 16 are turned off, a switch 19 of an integration controlling means 17 is turned on for a suitable time. Accordingly, the capacitor 19 allows the electric charge changed by the current II1 to be discharged by a constant current II2 generated by a constant current source 18 as the switch 19 is turned on. An integrating voltage Vx in the first integrating operation becomes a voltage corresponding to an incident position (x) of a spot light S. If the voltage Vx is set at a predetermined value beforehand, the voltage can be used as data of the distance to an object. Further, a time signal T2 which is obtained by a second integrating operation, that is, discharging the voltage Vx by a constant current can be used as distance data.

Filed: 1989-08-28
Abstract: PURPOSE:To perform an accurate diagnosis for a live-line insulation by arranging a sheath resistor and a local battery in addition to a circuit in parallel with a DC power supply of the bridge circuit equivalently to DC-like. CONSTITUTION:A sliding variable resistor (r) capable of reading out the resistance value is connected in series to a reference resistor R2 and these resistors are grounded through a DC current source P.

Title: Picture reader
Inventor: IRIYAMA TOKUO
IPC: H04N1/04
Filed: 1991-09-02
Abstract: PURPOSE:To minimize the deterioration in picture quality at reduction processing. CONSTITUTION:In the case of reducing an original picture into 4/5, for example, at first the original is fed excessively by one step of a pulse motor, and one line is read. Moreover, the original is fed by one line (equivalent to four steps in this embodiment) and the original is fed excessively by one step. Succeedingly one line is read and the original is fed excessively by four steps (equivalent to one line). Similarly, excess feeding and read processing are implemented. Then picture data by 10 lines substantially are read by eight lines in total at an interval of 1/4 line. That is, the picture is read while being reduced to 4/5. In this embodiment, since a step difference between adjacent lines is 1/4 line, the deterioration in picture quality is more improved than a conventional reader in which the reduction is implemented by interleaving one line.

Filed: 1993-09-07
Abstract: PURPOSE:To enable the compensation of wavelength dispersion by generating the phase conjugate light to the signal light from a first optical transmission line and having a second optical transmission line for transmitting this phase conjugate light. CONSTITUTION:A light signal transmitter 1 supplies the signal light modulated in accordance with an input signal to the optical transmission line 2. The signal light transmitted by the optical transmission line 2 is supplied to a phase conjugate light generating means 3. This phase conjugate light generating means 3 generates the phase conjugate light to the received signal light. The optical transmission line 4 transmits the phase conjugate light generated by the phase conjugate light generating means 3 and supplies this light to a light receiver 5. This light receiver 5 reproduces a demodulation signal corresponding to the input signal of the light transmitter 1. The optical transmission lines 2, 4 of such a case are optical fibers of, for example, a quartz system with which the wavelength dispersion arises inevitably. The optical transmission lines 2, 4 are subjected to the compensation of the wavelength dispersion. The wavelength dispersion is effectively compensated if the wavelength dispersion generated in the optical transmission line 2 is nearly equal to the wavelength dispersion generated in the optical fiber 4.
