Title: Variable voltage source
Inventor: NAGANO KATSUMI
IPC: H02M1/10
Filed: 1988-05-31
Abstract: PURPOSE:To improve the convenience for users, by fabricating a voltage control type voltage source by the use of a compound element functioning as a current control type voltage source. CONSTITUTION:A photocoupler PVC, the compound element, generates the output voltage for driving a load, optically couples an infrared light emitting diode LED to a photodiode array PDA, the photocell, and obtains the output voltage Vout corresponding to the size of the forward current from the photodiode array PDA. An operational amplifier A is a reversal amplifier whose input impedance and gain are equivalent to infinity, between the output terminal and reversing input terminal of which a feedback circuit by way of the above infrared light emitting diode LED is connected. When the input voltage Vin is thereby supplied to the operational amplifier A through an input resistor Rin, the current I will flow all to the diode. The input voltage Vout of the photocoupler PVC comes up to be proportional to the input as a result.

Title: Printer
Inventor: OKADA KOJI
IPC: B41J35/20
Filed: 1986-06-10
Abstract: PURPOSE:To suppress the vibration of a main solenoid when said solenoid rises, by varying one of the magnitude, the time or the waveform of a drive current for the main solenoid thereby bringing the final speed of a tape base during printing close to the final speed under correct printing. CONSTITUTION:When printing is performed, PD line is brought to H-level with UP line being held at H-level. The output from a NAND gate 62 has a waveform of P line, i.e. the NAND gate 62 produces a pulse which is produced from a pulse generator 51. The output from an AND gate 63 also has a waveform similar to P line, and a switching transistor 61 repeats ON-OFF operations so as to supply the power intermittently. Consequently, a main solenoid 4 is maintained in an attrated condition thus performing the printing. When correct printing is performed, a controller 54 feeds a signal to a sub-solenoid driver 52 so as to function said driver 52. Then the controller 54 brings the UP line to H-level with the PD line being held at L-level, and power is fed to the main solenoid 4 so as to lift a tape base 3 thus performing the correct printing. When the attraction force of the main solenoid is controlled such that the final speed of the tape base during printing is brought near to the final speed under correct printing, the vibration of main solenoid is suppressed when said solenoid rises.

Title: Data communication control system
Inventor: OKAMOTO MITSUHIRO
IPC: H04L29/02
Filed: 1986-06-10
Abstract: PURPOSE:To smooth data processings both at a transmission and a reception sides, by informing the data quantity stored at respective buffer area by the transmission side, at the time of transferring a sequence of data distributed and stored at plural buffers, and distributing and storing informed data quantity at the same number of areas as the transmission side by the reception side. CONSTITUTION:In case of sending a sequence of data distributed and stored at plural buffer areas 121 and 122 by a communication control circuit 13 at the transmission side to a data communication line 3, an information part 131 informs data quantities n1 and n2 stored at each of the buffer areas 121 and 122, to a data communication control circuit 23 at the reception side separately. At the time of receiving a sequence of data from a data communication control circuit 13 at the transmission side, by the data communication control circuit 23 at the reception side, a storing part 231 distributes and stores informed data quantities n1 and n2 respectively at the same number of buffer areas 221 and 222 as the buffer areas 121 and 122 at the transmission side. Therefore, a data processor 21 at the reception side processes the data having the same constitution as that targeted by a data processor 11 at the transmission side, as a targeted data.
Patent JP-S6022817-A (JP)
Title: Agc device
Inventor: KAMEOKA TAKAHARU
IPC: H03G3/02
Filed: 1984-06-28
Abstract: PURPOSE:To reduce the cross modulation distortion at the increase in an input level by allowing the 1st level adjusting device inserted to an amplifier in cascade connection to respond linearly to an AGC voltage and providing a region of a prescribed value not responding to the voltage to a part of the 2nd level adjusting device. CONSTITUTION:The level adjusting devices 2, 4 inserted between amplifiers 1 and 3 and between amplifiers 3 and 5 respectively receive an AGC output applied to a control input terminal 7 through drive circuits 6a, 6b respectively and decide the loss through the circuit. The 1st level adjusting device 2 receiving a control voltage via the drive circuit 6a increases linearly the loss through the circuit as the voltage applied to the control input terminal is smaller, and the 2nd level adjusting device 4 receiving the control voltage via the drive circuit 6b makes the loss through the circuit constant when the voltage at the control input terminal is smaller than a certain value and reduces linearly the loss through the circuit when the voltage is the value or over. Since the level is attenuated largely at the level adjusting device 2, the output of the amplifier 3 is not excessive and the cross modulation distortion at the increase in the input level is decreased.
