Title: Eccentric pump
Inventor: ITOU KAZUICHI
IPC: F04C15/00
Filed: 1982-08-19
Abstract: PURPOSE:To provide a simple seal member to lessen the pulsation of discharged fluid by giving eccentric motion to an eccentric ring to generate a pumping action without rotating a pump shaft. CONSTITUTION:While a spherical body 35 of a spherical bearing 34 rotates eccentrically when a motor shaft 8 rotates, a socket 33 is not rotated since the revolution of a pump shaft 10 on its own axis is restrained by a rotation stopper 44, and only the eccentric motion of the spherical body 35 is transmitted so that eccentric rings 16, 17 move eccentrically about the center O of a center bearing 11. When contact portions of the outer peripheral surface of the eccentric ring 16 and the inner peripheral surface of a hollow chamber A move counterclockwise along with said eccentric motion, the volume of a suction chamber Pi divided by a partition member 21 increases and the volume of a discharge chamber Po decreases. Thus, fluid introduced through a suction port 26 and a suction path 24 is pressurized and discharged to a discharge path 25. The eccentric ring 17 side pumping action generates just 180 deg. of phase difference so that the pulsation of fluid is cancelled by each other. A diaphragm 43 ensures the sealing property of the hollow chamber A.

Title: Exhaust gas purifier for internal combustion engine
Inventor: KATOU TAKASHI
IPC: F02M7/17
Filed: 1982-08-21
Abstract: PURPOSE:To improve the specific fuel consumption of an engine during high-load operation not required high output and heighten the output of the engine during high-load operation required high output, by detecting the high-load operation of the engine to entirely close a solenoid valve in an air bleed passage at a predetermined lag time after the starting of the high-load operation so that the mixture of the engine is not made too thick if high output power is not required. CONSTITUTION:When a throttle valve 11 is almost entirely opened, namely, high- load operation approximate to maximum-load operation is effected, a throttle switch 58 is turned on and the output voltage of a delay circuit 54 is made high after a predetermined lag time to turn off an analogue switch 52. Therefore, a voltage applied to a voltage-current converter 53 is made zero at the predetermined lag time after the starting of the high-load operation. As a result, a solenoid 43 is deenergized to close a valve port 37 in an air bleed passage 35 to feed a too thick mixture into an engine cylinder. Engine output is thus heightened only when high output is needed.

Title: Displacement detector
Inventor: DOI HIROMASA
IPC: G01B11/26
Filed: 1990-05-31
Abstract: PURPOSE:To detect displacement such as the position and inclination of an object with small-sized constitution without being limited with an object by outputting a signal corresponding to the difference between the outputs of the inside and outside photodetectors of a sensor. CONSTITUTION:When the object 6 is irradiated with light from a light source, the light is received by the sensor 14 through an image forming lens 15. The signal corresponding to the difference between the output of the inside photodetector 21 of the sensor 14 and the output of the photodetector 22 is adjusted to a reference value. In this state, when the object 6 is farther than a focus position, the light receiving quantity of the outside photodetector 22 is increased and when the object 6 is in front of the focus position, on the other hand, the light receiving quantity of the outside photodetector 22 is decreased, so a displacement detecting circuit 31 finds the difference between the outputs of both and outputs the signal corresponding to the difference, so that the position of the object 6 can be detected. When the object 6 slants to an optical system, the outputs of one divided photodetecting element and the other divided photodetector become different, so the inclination of the object 6 can be detected from the signal corresponding to the difference.

IPC: G05B19/23
Filed: 1982-08-23
Abstract: PURPOSE:To prevent oscillation after a stop and to improve an operation speed by providing a nonholding range wider than a stop range. CONSTITUTION:A controller 1 rotates a motor 3 at a commanded speed in a commanded rotation direction to output a driving signal for rotations as many as a commanded number of pulses; the motor 3 rotates until a target position and then stops. In this case, the nonholding range wider than the stop range is provided and after a temporary stop in the stop range is judged, control for returning the motor to the nonholding range only when it goes beyond the nonholding range is performed. Thus, recontrol is started only when the motor moves beyond the nonholding range, so no oscillation after the stop occurs and the next command can be fetched immediately, so that the operation never decreases in speed. Consequently, the oscillation after the stop is prevented and the operation speed is increased.
