Title: Optical pickup
Inventor: EZAWA HIROSHI
IPC: G11B7/135
Filed: 1991-10-25
Abstract: PURPOSE:To thin an optical pickup by placing one part of a light emitting element, a light condensing element and a light receiving element, etc., on a face side opposing to the recording medium surface of a movable body and setting a mirror at a smaller angle than 45 degree to the recording medium surface. CONSTITUTION:An opening control part 13 is provided in the inside of an objective lens 8. Further, the mirror 14 is fixed downward (Z direction) the objective lens 8 so that a light beam outgoing from the light receiving and emitting element 9 changes an optical path in the direction of the objective lens 8. In such a case, since the angle to the recording medium 15 surface of the mirror 14 is set smaller than 45 degree, the height C in the direction of Z of the mirror 14 is reduced than a conventional method. Further, when the distance between the opening limiting part 13 provided in the inside of a holder 7 and the mirror 14 is defined as the same, since the mirror 14 is made close to the objective lens 8, the measure D, as well is reduced.

Title: Accumulator fuel injection device for diesel engine
Inventor: AKEDA MASAHIRO
IPC: F02D1/08
Filed: 1986-11-25
Abstract: PURPOSE:To make the precise determination of injection time possible by the simple composition of a fuel injection device by communicating a pressure relief valve for determining injection time with the valve closing pressure fuel chamber of a fuel injector through a fuel injection pump. CONSTITUTION:A pressure relief valve 19 for determining injection time is communicated with the valve closing pressure fuel chamber 85 of a fuel injector 29 through a fuel injection pump 26. Thus, when the outlet passage 24 of a valve box 56 connected to the fuel injector 29 communicates with passages 59 toward a pressure relief valve body, fuel in the fuel chamber 85 is set free outside through the pressure relief valve 19, and pressure in the fuel chamber 85 is therefore reduced to open an injection valve 88. Thus the injection time of the fuel to the fuel injector 29 depends on the timing at which the outlet passage 24 communicates with the passage 59. Since this timing is determined by the motion of a valve body 57 being in common with the valve 18 for determining fuel supplying time which interlocks timingly with a crankshaft, the injection time can be precisely determined with the timing control made on a crankshaft.

Title: Signal generator
Inventor: REIMONDO ERU FURAIDO
IPC: H03L7/187
Filed: 1988-11-04
Abstract: PURPOSE: To selectively switch a frequency of an output signal in a short settling time through a selectable sequence by generating a frequency selection signal representing an output frequency selected in response to input information and providing pre-tuning information corresponding to an output frequency selected by a pre-tuning means. CONSTITUTION: A desired digital pre-tuning signal is given to a pre-tuning D/A converter 31 on a line 32, a current output of the D/A converter 31 is given to an amplifier 33 with a short settling time at a high speed, a current signal is changed into a voltage signal and the voltage signal is given directly to a VCO tank circuit on a line 26. In the case of the high speed hop mode, a pre-tuning trigger command is sent simultaneously as digital pre-tuning data. Since a pre-tuning trigger bypasses a pre-tuning low pass resistor, the speed of the pre-tuning circuit is increased and a high speed pre-tuning change is fed to a VCO 1. Furthermore, a pre-tuning digital bit corresponds to a selected output frequency. Thus, the frequency of an output signal is selectively switched in a short settling time.

Filed: 1994-11-15
Abstract: PURPOSE: To provide a controller for closing a window which decides correctly the presence of the catching of some foreign matter even when the operating state of a motor is varied slowly during the closing operation of the window. CONSTITUTION: When the speed of a motor M is lowered slowly accompanied by the increase and decrease of the speed due to the variations of its temperature and the voltage of its power supply, etc., in spite of the catching of no foreign matter, its rotational speed which is in an increasing process is updated in a microcomputer 60 repeatedly as a reference rotational speed Vp .

Title: Method and device for controlling power converter
Inventor: OKUYAMA TOSHIAKI
IPC: H02P27/08
Filed: 1994-10-20
Abstract: PURPOSE: To provide a power converter control method by which the output voltage distortion caused by the dead time of a power converter can be suitably minimized always by controlling the compensating amount of the output voltage distortion to the optimum value. CONSTITUTION: In a power converter control method by which the output voltage distortion caused by a power converter is compensated by using the compensating signal corresponding to the output current of the power converter, the output voltage distortion (residue after compensation) is estimated based on the output voltage command value and output current value of the converter and the magnitude (compensating amount) of the compensating signal corresponding to the output current is adjusted based on the estimated value. Therefore, the control precision of the power converter can be improved, because the output voltage distortion of the power converter can be always minimized and the torque ripple of a motor connected to the power converter and higher harmonics of an AC power source can be reduced.

Abstract: PURPOSE:To utilize the effective use of frequency by providing a storage section storing a slave set disabling to attain excellent signal transmission with a master set to a repeater and using the repeater so as to relay only the signal by the slave set stored in the storage section thereby preventing the overlapped signal sent to the master set. CONSTITUTION:When a signal sent from a slave set B is received by a repeater C, the transmission signal of the slave set B is detected to detect the code of the slave set B. The code is compared with a code stored in a storage section 3, then a control section 4 discriminates whether the reception signal is the transmission signal of the slave set B designated for the relay or not. When the reception signal is the signal from the designated slave set B, the reception signal is amplified and sent from the transmission section 2 and when the reception signal is not the transmission signal from the designated slave set B, no transmission is given from the transmission section 2. In using the storage section 3, if it is required to change the slave set B of the relay due to any cause, it is coped with easily by replacing the storage section 3.
