Title: Driving circuit for dc motor
Inventor: UEHARA MASAHIRO
IPC: H02P6/20
Filed: 1985-07-10
Abstract: PURPOSE:To shorten the starting time of a DC motor by simple constitution by continuously making currents to flow through a motor coil on the starting of the motor and controlling pulse width modulation after the speed of the motor reaches speed close to specified one. CONSTITUTION:A Hall element 1 detects the position of a magnetic pole for a motor, and outputs a Hall signal. A polarity discriminating circuit 2 outputs a polarity signal in the Hall signal, an absolute value circuit 3 outputs an absolute value signal in the Hall signal, and a PWM circuit 4 pulse-width modulates the absolute value signal and outputs a pulse-width modulation signal. A starting signal from a comparator 8 reaches a high level on starting, and currents continuously flow through a motor coil 20. When the speed of the motor reaches speed close to specified one, the starting signal shifts to a low level. Accordingly, currents interrupted by the pulse-width modulation signal flow through the motor coil 20.

Title: Charging signal transmitting circuit
Inventor: YAKU TOSHIO
IPC: H04M15/00
Filed: 1982-08-30
Abstract: PURPOSE:To attain miniaturization and light weight and to reduce noise generated at the transmission of charging signal, by operating a switching transistor (TR) just before the leading edge and trailing edge of a polarity inverting pulse so as to decrease the level of a signal current. CONSTITUTION:A low pass filter is arranged between a contact of a polarity inverting relay and a channel, and switching TR is arranged between the polarity inverting relay and a power supply respectively and the switching TR is operated just before the pulse leading and trailing of the said polarity inversion. In inverting the polarity of the channel, since no current flows to the channel, no noise is generated. Then, the 2nd pulse is applied to a filter F and the collector current of a TR1 is decreased gradually. The line current is inverted through the polarity inversion in this case and an MP relay is restored while the current of the channel is zero. The noise is reduced remarkably by controlling the waveform of the current in this way, but a slightly rapid changing point remains in the waveform, which might cause a noise, then the waveform is smoothed further with an LPF.

Title: Inductance component and manufacture thereof
Inventor: HARADA SHINJI
IPC: H01F17/04
Filed: 1988-06-17
Abstract: PURPOSE:To improve high-frequency magnetic characteristics and magnetic shield by incorporating winding within a mixture of magnetic powder and low- melting point glass powder and performing integration with a low-melting point glass which is softened and melted below a temperature where sintering of magnetic powder starts after the formation under pressure or under application of pressure. CONSTITUTION:A winding 3 is incorporated between a magnetic powder 1 and the winding 3 and the magnetic powder 1 are integrated by a low-melting point glass 2. Since the magnetic powder 1 is fused and hardened by a low- melting point glass 2, the area between the powder is electrically isolated by glass constituents and a high-resistance core material can be obtained regardless of proper resistance of the magnetic powder 1. Namely, a high resistance can be obtained even in an allow or ferrite material where resistivity of the magnetic powder 1 is low. Furthermore, since the winding 3 is incorporated into the magnetic powder 1, there is no external leakage of magnetic flux and an efficient magnetic characteristics can be obtained. It eliminates the need for magnetic shield owing to an improved high-frequency magnetic characteristics.

Abstract: PURPOSE:To avoid the loss of a desired signal after the end of application of disturbance wave and to reduce the deterioration of the disturbance wave eliminating capacity to the disturbance wave of pulse train, by turning the value of a storage circuit into the initial value of the antenna weight through a deciding circuit of an adaptive antenna having a correlation loop. CONSTITUTION:A disturbance wave applied to an antenna element 11 of an array 12 is decided through a deciding circuit 19, and the weight is stored in a storage circuit 20 in case no disturbance wave is applied to a weight circuit 13. Then the weight corresponding to the conventional disturbance wave of a storage circuit 21 is put into an initial value setting circuit 22 to start learning. Then a pattern of beam is decided. When the application of the disturbance wave is over, the learned weight is stored in the circuit 21. The weight of the circuit 20 is put into the circuit 22. Both the presence and absence of application of the disturbance wave can be set as the initial value. This can avoid the loss  of a desired signal for a long period of time. Thus the deterioration can be  reduced for the disturbance wave eliminating capacity to the disturbance wave  of pulse train.

Filed: 1995-06-19
Abstract: PURPOSE: To make it possible to suppress unnecessary high frequency signal radiation and power consumption by transmitting only print data of the case that previous print data is different from this time print data, and reducing the transmitting amount of the data. CONSTITUTION: A print data comparator 26 compares the signal PDAT of print data of this time with the signal TREPDAT of print data of previous time, and sets a signal CMP to a high level if both coincides or sets it to a low level if both are different. A print data transmitter 27 transmits the print data PDAT to a head 28 as signal SDAT when the signal CMP is a low level. When the signal CMP is a high level, nothing is transmitted to the head 28. Accordingly, the transmitting amount of the print data is reduced, and the unnecessary radiation and power consumption can be suppressed.
