Title: Drive system for pulse motor
Inventor: SHIRAKAWA MITSUAKI
IPC: H02P8/14
Filed: 1983-07-29
Abstract: PURPOSE:To reduce the capacity of a drive transistor by generating the optimum torque for a load in a pulse motor, thereby alleviating the load of the drive transistor. CONSTITUTION:A CPU2 first reads out a timer value from a constant table stored in a memory 1 by the program control, and sets the values in timers 3, 4. The values set in the timers 3, 4 are represented by Tan, Tbn. Then, the timer values Tan, Tbn are inputted to the set terminal S and the reset terminal R of an FF5, thereby obtaining the pulse of time width represented by (Tbn-Tan). The CPU2 repeats the operation, and sequentially applies the current control pulse to drive transistors TR1. Accordingly, the motor drive current adapted for the load can be obtained by the current control pulse by setting the timer values Tan, Tbn to the values adapted for the load.

Title: Television channel selector
Inventor: SAKAMOTO YOUICHI
IPC: H04N5/44
Filed: 1978-11-07
Abstract: PURPOSE: To perform tuning operation without digital noises by a phase lock loop system which tunes to the video carrier frequency of a desired reception channel and a tuning system which oscillates at a sound carrier frequency corresponding to the frequency.  
     CONSTITUTION: Corresponding to the video carrier frequency of a desired reception channel, a phase lock loop system oscillates at a local oscillation frequency. The lock state of the phase lock loop system is detected by PLL/search switch 41 to detect oscillations of the phase lock loop system nearly at a desired local oscillation frequency, thereby changing oscillations ober from the phase lock loop system to a search tuning system. Therefore, no digital noise is generated in a reception state. For tuning to a sound carrier, search tuning is operated in a direction in accordance with the sound carrier on the basis of a locak oscillation frequency equivalent to a video carrier.

Title: Switched reluctance motor
Inventor: SAKUMA MASASHI
IPC: H02K19/10
Filed: 1998-05-20
Abstract: PROBLEM TO BE SOLVED: To reduce deformation of external circumference to reduce noise level by forming for an annular yoke, by forming a part located in the external side of radius direction of external edge portion of an annular yoke of a stator core and a plurality of through-holes for dividing the magnetic pole in the radial direction. SOLUTION: Since the bottom of a coil accommodating slot forming between two adjacent magnetic poles S4a in the circumference direction of a stator core S4, is formed with two straight lines, width of the annular yoke S4b becomes smallest at the center A between two magnetic pole forming portions S4a, and this width is set considering the maximum magnetic flux which is determined from a motor output torque. As a result, the width of the annular yoke S4b becomes larger than the minimum width at the center between two magnetic pole portions S4a to result in magnetic allowance. Therefore, a through-hole S4c is formed within a range which does not result in magnetic problems in the annular yoke S4b for having, the external edge portion of each magnetic pole portion S4a and annular yoke S4b divided in the radius direction.  Accordingly, the deformation of external circumference of stator core due to magnetic attracting force is reduced and noise level is reduced.

On the other hand, a signal A is output from a pulse distributor 8 for applying a firing pulse to the inverter 2 in a current interruption operating range when the inverter starts commutating, a pulse shift command is applied to the regulator 7 by a timing circuit 11 to store the firing angle immediately before it. When the detection signal C of Id=0 is obtained from a detector 10, the pulse shift command is eliminated to restart the operation.

Title: Satellite-mounted repeater
Inventor: YAMAMOTO KAZUICHI
IPC: H04B7/15
Filed: 1992-05-29
Abstract: PURPOSE:To make a frequency highly stable while keeping communication by making the local oscillator of a frequency converter and a beacon oscillator synchronize with a common reference oscillator and providing a frequency adjusting function on the reference oscillator. CONSTITUTION:This satellite-mounted repeater generates a local oscillating frequency used for frequency converters 6-1-6-n converting the frequency into an up-link frequency and a down-link frequency and the beacon frequency of the beacon oscillator 8 by using a common original frequency generated from a reference oscillator 9 whose oscillating frequency is variable. Thus, the frequency stability of the satellite-mounted repeater depends only on the frequency stability of the reference oscillator 9. When the frequency of the reference oscillator is fluctuated, the high stability of the frequency of the satellite-mounted repeater is realized by adjusting the frequency of the reference oscillator so as to eliminate the fluctuation. Furthermore, the frequency is adjusted while keeping the communication.

Abstract: PURPOSE:To obtain the compression of a pulse having long duration by converting a pulse whose frequency linearly changes to a pulse having duration when the frequency linearly changes in terms of frequency and compressing a section which changes by the use of a surface acoustic wave element. CONSTITUTION:A pulse signal is obtained by making the reception pulse from a target pass through a frequency converter 6. The signal is two-branched, one of which is made to pass through the surface acoustic wave element 1a and then through the surface acoustic wave element 1b to obtain a compressed pulse. The other of two-branched signals, on the other hand, is made to pass through the surface acoustic wave element 1 to obtain the compressed pulse. The two compressed pulses thus obtained are made to pass through respective detectors 7 to be envelope-detected and synthesized by a synthesizing device 8 thereafter. Thus, the desired compressed pulse is obtained.
