Title: Exhaust gas recirculation control device for engine
Inventor: KOMINAMI MASAYA
IPC: F02D41/14
Filed: 1985-09-30
Abstract: PURPOSE:To enable reduction of the size of a heater attached to an O2 sensor, by a method wherein, in a device which controls the opening of an EGR valve according to an output from an O2 sensor detecting O2 concentration in suction air mixed with EGR gas, the O2 sensor is so constituted as to be capable of being heated by means of exhaust heat. CONSTITUTION:An EGR valve 10 is located between pipes 11 and 12 through which an exhaust pipe 9 and a suction pipe 2 are intercommunicated, and is controlled by an electronic control circuit 14 according to an output from an O2 sensor 6 having a detector 13 for the number of revolutions of an engine, a suction air amount detector 4, and a heater 7 adapted to heat the sensor to a normal working temperature. The O2 sensor 6 is mounted in a spot, to which heat is transferred through an exhaust pipe 9, i.e., in the vicinity of the exhaust pipe 9 so that the sensor is heated by means of exhaust gas from an engine 1. This enables a small and low power device to be employed as the heater 7 adapted to heat the O2 sensor 6 cooled by suction air, and enables reduction of a cost and saving of a power.

Title: Roller unit for manufacturing tape
Inventor: YOKOTA TERUHISA
IPC: G11B5/84
Filed: 1982-12-14
Abstract: PURPOSE:To shorten time required, by composing a clutch of movable friction plates coupled to a roller shaft and friction plates secured on a roller, to forcedly drive the roller to a rotational frequency necessary for processing the tape and to cause the roller to perform a follow rotation after reaching the rotational frequency. CONSTITUTION:When a roller unit is stopped, friction plates 9a on the tips of pendulums 9 are pushed on friction plates 8 inside a roller 5 by tension springs 11. When a pulley 13 is rotated, the roller 5 is forcedly driven until the centrifugal force of each pendulum 9 exceeds the force of the tension spring 11. When the rotational frequency of the pulley 13 has become such that the centrifugal force of the pendulum 9 is stronger than the force of the tension spring 11, the friction plate 9a on the pendulum comes off that 8 on the roller 5 so that it is not forcedly driven, very small torque is transmitted from a roller shaft 7 to the roller 5 through a radial bearing 6 and the roller performs a follow rotation.

Title: Micro-driver for piston pump
Inventor: ISHII MIEKO
IPC: F04B13/00
Filed: 1986-09-19
Abstract: PURPOSE:To prevent a pressure variation and a pulsating flow from occurring, by installing a driver giving such an exciting current that varies at each one input pulse by degrees as an input signal for a pulse motor and makes this motor so as to be rotated at a small angle, and also a control circuit making input pulse width variable. CONSTITUTION:When a direction of motion in a piston 57 is selected from a positive direction to a negative direction, if a drop or a rise in discharge pressure occurs due to the response delay or the like of a check valve 61, this pressure variation is detected by a pressure detector 60, and it is fed back to a control circuit 50 together with a piston position signal out of a piston position detector. The control circuit 50 transmits pulses and microfeed signals to be delivered continuously at optional time intervals to a pulse motor drive unit 51, and then such an exciting current as varying at each one input by degrees and rotating it at a small angle is delivered to a pulse motor 52, thus a variation in pressure inside a pump case 59 is relieved.

Title: Transmission type projecting screen
Inventor: TODE HIDEKAZU
IPC: G03B21/62
Filed: 1989-08-24
Abstract: PURPOSE:To reduce amount of outside light reflecting toward an observer by forming the vertical cross section of the luminous flux transmission part of a lenticular lens into a tooth-shape. CONSTITUTION:The luminous flux transmission part 8 of the lenticular lens 5 has a tooth-shaped vertical cross section formed from a slant face 8a, which slants toward a floor, and a return face 8b. Since the return face 8b is formed into a horizontal plane, all luminous fluxes 10 from a cylindrical lens 6 are transmitted through the slant face 8a, and propagate toward an observing direction 12 without light loss at the face 8b. Also, since the slant face 8a slants toward the floor, the outside light is reflected toward the floor; outside light component included in the observing direction 12 are extremely reduced, therefore video contrast is greatly increased. There is also a component made incident on the face 8b after the outside light is reflected from the slant face 8a; however, the reflection can be prevented by coating the face 8b with black absorbing agent.

Title: Driving stop controller of unmanned truck
Inventor: KATO YOSHITO
IPC: G05D1/02
Filed: 1984-10-18
Abstract: PURPOSE:To attain the highly efficient transport with an unmanned truck by detecting that the unmanned truck reaches a reference position, delivering a deceleration command when the coincidence is obtained between the distance traveled actually from the reference position and the stored distance and then delivering a stop command when the truck reaches a desired station. CONSTITUTION:The distance traveled actually from a reference position P is measured in the form of the number of output pulses for an unmanned truck 18 after the truck 18 passed through the position P. While the pulse set value Kn showing the distance between the position P and a deceleration start position Q corresponding to a station 16h is stored in a RAM46. A CPU44 compares the value Kn with the actual count value K of pulses. When it is discriminated that the coincidence is obtained between said both values, the CPU44 supplies the deceleration command signal to a motor drive control circuit 30 to reduce the revolving speed of a motor 28. When a light sensor 52 senses a stop position R, this sense signal is sent to the CPU44. Then the CPU44 supplies a stop command signal to the motor 28 via the circuit 30.

Abstract: PROBLEM TO BE SOLVED: To reduce leakage current which flowed into a line, up to a motor. SOLUTION: A motor is set to a six-phase motor, consisting of two coil winding W1 and W2 whose phases differ by 180 deg., an inverter is set to two sets of three-phase inverters 11 and 12 that are driven by a PWM pattern where on/off change to the opposite, the inverters 11 and 12 are connected to the motor coil winding W1 and W2 by L-C-L noise filters A1 and A2, and the two sets of inverters 11 and 12 are connected from the point between inductance L1 at the inverter side of the noise filters A1 and A2 and the motor coil winding W1 and W2 by a capacitor C12. Since the higher harmonic current of the two PWM patterns is set at opposite polarities, leakage current is canceled and no leakage current exist outside the motor (prior art). The harmonic current flows to the core part of the motor via a floating capacity.  The harmonic current is rejected by the noise filters A1 and A2 and at the same time is made to bypass by the capacitor C12.
