Title: Noncontact power supply transfer system
Inventor: OWASE JOJI
IPC: H01F38/18
Filed: 1994-12-08
Abstract: PURPOSE: To realize noncontact power supply to a carrier by a constitution wherein the carrier is transferred while feeding a motor with power from feeders located in two openings of an E-shaped core and when the carrier arrives at the end of a unit power supply section the carrier rides over a microgap and transferred to an adjacent unit power supply section. CONSTITUTION: Each carrier 1 is transferred while being fed with power from feeder lines 4a, 4b located in two openings of an E-shaped core. Upon arriving at the end of a unit power supply section, the carrier rides over a microgap and transferred to an adjacent unit power supply section. The carrier 1 is transferred in one direction at a constant speed while keeping a predetermined interval and when the speed of one carrier drops due to some cause and a following carrier 1 enters into the adjacent unit power supply section, a controller 6 decreases the output current from an inverter 5 in the unit power supply section where the following carrier is present to lower the transferring speed of the following carrier thus preventing two carriers 1 from entering into one unit power supply section simultaneously.

Title: Atmospheric pressure detection for engine operation
Inventor: ISHIDA KATSUMI
IPC: G01L23/24
Filed: 1987-12-26
Abstract: PURPOSE:To rationalize correction of an air-fuel ratio, setting of an acceleration condition, etc., in a high land with only one pressure sensor by correcting an inlet pipe pressure value by a reference pressure difference, which is obtained with the rotational frequency of an engine as the variable at the time of detecting the inlet pipe pressure, to obtain the atmospheric pressure. CONSTITUTION:When the operation state of the engine is controlled by an ECU 9, the reference pressure difference which is the difference from the atmospheric pressure value in a low land detected by a pressure sensor 5 in an inlet pipe 2 of the engine at the time of opening a throttle to its full width in the low land is preliminarily stored in the ECU 9 as data with the rotational frequency of the engine as the variable. When this method is applied to a supercharged engine, the value obtained by subtracting the reference pressure difference with the rotational frequency of the engine at the time of inlet pipe pressure detection as the variable from the inlet pipe pressure value is calculated as the atmospheric pressure with a high precision at the time of detecting the inlet pipe pressure because the reference pressure difference which has the rotational frequency of the engine as the variable and is the difference between the pressure value of the inlet pipe 2 and the atmospheric pressure value in the low land is stored in the ECU 9, and the engine is always controlled in the atmospheric pressure corrected state. Consequently, the inlet pipe pressure as well as the atmospheric pressure is detected to rationalize correction of an air-fuel ratio, setting of an acceleration condition, etc., in a high land with only one inlet pipe pressure measuring sensor.

Title: Method to control motor
Inventor: NOJIMA TAKASHI
IPC: H02P8/18
Filed: 1993-12-27
Abstract: PURPOSE:To improve the vibration and noise of a motor by a motor control method in which the electric power supplied to the winding of the motor is controlled by dividing the driving excitation of the motor by increasing or decreasing the dividing number depending upon the drive exciting time. CONSTITUTION:An MPU 1 outputs a prefixed duty pulse to a PWM unit 2 at a certain frequency at every excitation. A current control transistor 6 is energized by the outputs E and F of the unit 2 and supplies an electric current to a stepping motor 4. The PWM value approximates the current curve flowing to the motor 4 to a sine wave by dividing the drive excitation into a plurality of parts and setting an appropriate duty in each part. For example, drive excitation of 500PPS is divided into 40 parts and drive excitation of 500PPS is divided into four parts. When the dividing number of PWM is changed in accordance with the driving frequency of the motor 4, an electric current having a smooth sine waveform can be made to flow to the motor 4 at any frequency. Therefore, the vibration and noise of the motor 4 can be improved, because the waveform of the current to the motor 4 becomes smooth from a low-speed rotation to a high-speed rotation.

Title: Fm receiver
Inventor: NAKAYAMA KIYOSHI
IPC: H04B7/08
Filed: 1987-12-28
Abstract: PURPOSE:To prevent the occurrence of nonlinear distortion in a high frequency component due to a high frequency switching diode by attenuating the level of a high frequency signal from an antenna. CONSTITUTION:A high frequency signal from an antenna 1a or 1b selected by an RF switching circuit 3 is attenuated to a level where no nonlinear distortion of a high frequency switching diode of the RF switching circuit 3 takes place due to a variable high frequency attenuation circuit 2a or 2b by the control of the AGC voltage with a comparatively broad band of a front end 5, attenuated further by a variable high frequency attenuation circuit 4 to prevent saturation or crosstalk in a mixer stage. Thus, the nonlinear distortion of the high frequency switching diode of the RF switching circuit 3 does not take place even in a strong electric field district.

Filed: 1988-12-29
Abstract: PURPOSE:To attain stable display at varying speed reproduction by supplying a pseudo vertical synchronizing signal to a control circuit of a liquid crystal display device in place of a vertical synchronizing signal in a video signal at the varying speed reproduction. CONSTITUTION:The write state is attained in a field of a video signal with less noise, a scanning signal is supplied to a liquid crystal display device 8 and the supply of a scanning to the liquid crystal display device 8 is stopped in a field in which an undesired signal with mush noise is generated such as a reproduction signal generated at the still reproduction mode of a VTR. Since the liquid crystal display device 8 holds the display by the display signal of a preceding field, a noiseless reproduced picture is obtained. Furthermore, the picture is displayed correctly by using the pseudo external vertical synchronizing signal so as to obtain the vertical synchronization of the liquid crystal display device 8 in the varying speed reproduction mode.

Filed: 1990-11-29
Abstract: PURPOSE:To control raw material charge in high accuracy without interrupting the charge by always executing correction to factor in basic function based on the newest intersection information as the automatic control result in a raw material discharging apparatus for controlling the opening degree of a flow rate adjusting gate. CONSTITUTION:The opening degree phin of flow rate adjusting gate 12 at the time of dumping the raw material at (n) the charge, is fixed with the first base function in the equation I showing approximated curves composed of plural straight lines connected to the intersection and using raw material discharging velocity W/T as variable. The raw material weight Wn in a raw material incorporating vessel before starting this dumping, is obtd. and also the aimed raw material discharging velocity Wn/Tn for changing this raw material with the prescribed dumping time Tn is substituted into the equation I to obtain the actual opening degree value [phin]. The opening degree of gate 12 is adjusted to this value, and the dumping is executed and also the actual dumping time Tr(n) to dumping completion is measured. From this value and the weight Wn, the actual raw material discharging velocity Wn/Tr(n) is obtd. Based on this value and the measured actual opening degree value [phin]r, the factor (an) in the equation I is corrected to obtain the second base function in the equation II and successively, the dumping of raw material at (n+1)th is executed as the same operation.

Abstract: PROBLEM TO BE SOLVED: To provide a photodetector, and the method and device for reproducing a wobble signal of an optical disk, capable of always reproducing accurate wobble signal using a simple constitution, even for the optical disk having the high information recording density. SOLUTION: By using an octopartite photodetector 31 in place of the conventional quadripartite photodetector, a reflected light is made incident on the photodetector 31, in such a manner that a radial direction R and tangential direction T are made to coincide.

Furthermore, when the wobble signal is reproduced, only output signals of four center photodetecting areas A-D are used to remove the reflected light component from adjacent tracks. When an RF signal, focus error signal FE and tracking error signal TE are produced, the output signals of all photodetecting areas A-H are used.
