Title: Method controlling operation of ac rotary machine
Inventor: KAWABATA TAKAO
IPC: H02P1/30
Filed: 1978-06-30
Abstract: PURPOSE: To prevent an AC rotary machine from abruptly accelerating or braking accelerating the machine until it coincides with the frequency of a second power supply by a first variable frequency power supply and starting the adjustment of the frequency and phase angle of the first power supply when both the phases become concident.  
     CONSTITUTION: An AC rotary machine M is accelerated via an oblique signal generator 2 and a voltage controlled oscillator 3 by a variable voltage variable frequency inverter 1. A phase difference detecting circuit 5 applies a signal proportional to the phase difference of the output voltages of the inverter 1 and a commercial frequency power supply 6 to an amplifier 4 in an automatic synchronization control circuit, and holds an internal memory at the instantaneout moment that the machine is completely accelerated by the holding circuit 7 so that the output of the circuit 5 becomes zero to thereby hold a relay K 1  for the ampifier 4. Since the phase difference is zero at the moment that the circuit 5 is alive to produce no kick voltage due to the above reason, it can smoothen the frequency in variation when applying to the commercial power supply.

IPC: G09G3/20
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To prevent the malfunction at the time clock skews are generated in external input signals. SOLUTION: An effective timing detecting circuit 104(2n) outputs the pulses of an 'H' level only for a period when a holding part 102(2n) is completely turned ON according to external input signals A, B.

Abstract: PURPOSE: To facilitate and secure the visual recognition of open circuit of a power source line by forming an indication mark in an operating member of a manual switch, which is automatically turned to the off-position side when the pushing force is applied. CONSTITUTION: When an operating member 64 of a manual switch 26, which is arranged corresponding to a battery box for housing plural batteries, is pushed, the operating member 64, in which the energizing force is always given from the on-position to the off-position by a coil spring 66, is turned from the on-position to the off-position.

Title: Method for bending dumping metallic material
Inventor: CHINO NAGATSUGU
IPC: A47H1/04
Filed: 1991-03-18
Abstract: PURPOSE:To prevent deformation such as a wrinkle, a break and a twist from being generated by cooling a long sized damping metal formed to a singular cross section shape to a specified temperature, then, bend-it. CONSTITUTION:After the long sized damping metal 1 formed into a singular cross section shape such as a U-shape, a C-shape, etc., is cooled to 10 to 80 deg.C, the dumping metal 1 is bent by a roll forming machine, etc., into a specified shape such as an arcuate shape, an S-shape, an L-shape or an other shape curved in the longitudinal direction. The fluidity of viscous and elastic resin 3 of an intermediate layer between the metallic plates 2, 2 increases at >10 deg.C, the tensile shearing force of the metal 1 reduces and defects are easily generated when forming is performed. The resin 3 changes into a vitreous state at <-80% and the resin 3 is broken at the time of forming. When the metal is worked in the range of 10--80 deg.C, deformation such as a wrinkle, a break and a twist can be prevented from being generated.

Title: Time axis error correction circuit
Inventor: TAKAHASHI HIROAKI
IPC: H04N5/95
Filed: 1990-03-30
Abstract: PURPOSE:To detect and correct a so-called velocity error and a time axis error within 1H by detecting a phase difference of a burst signal before and after 1H. CONSTITUTION:An output of a phase comparator circuit 19 is increased or decreased corresponding to a speed error shown in Figure (d). Then a burst signal is split into two parts, and a sampling clock for time axis correction in following to a recovered video signal at a high speed is obtained by using the burst signal so as to apply phase comparison between burst injection and 1H period. Moreover, a speed error for 1H is detected accurately without being much affected of noise. Thus, time axis fluctuation or speed error including a high frequency component due to an impact error or the like is eliminated at a high speed accurately.
