Title: Gas laser oscillator
Inventor: OKUMA SHINJI
IPC: H01S3/0971
Filed: 1985-12-26
Abstract: PURPOSE:To keep discharge stable, and to improve the efficiency of laser oscillation by connecting discharging resistors in parallel with both ends of a DC high-voltage power supply, one end thereof is grounded, through a main capacity and a spark gap switch, and connecting a peaking capacity and a gas laser tube in parallel through a coil and a saturable reactor in series. CONSTITUTION:When a switch 13 is triggered and conducted, a laser tube 17 is supplied with the charging charges of a capacity 12. The charging rise of a capacity 16 is delayed by a coil 15 at that time, and preliminary ionization is conducted sufficiently by means of a trigger electrode 18 during the rise. A saturable reactor 19 is turned ON because of large discharging currents at that time, and currents are regulated only by the coil 15. When main discharge is generated by the laser tube 17 and discharging currents are reduced, the saturable reactor 19 is turned OFF, and regulates currents in cooperation with the coil 15. Consequently, voltage between main electrodes for the laser tube is not oscillated and gradually approaches to zero potential. Accordingly, no arc discharge is generated, and the laser tube maintains stable discharge. Discharging resistance 14 can be increased sufficiently, and loss in the resistor 14 is reduced, thus improving the efficiency of laser oscillation.

Title: Mechanism for preventing ink ribbon from being caught
Inventor: OKAMOTO FUMIAKI
IPC: B41J35/08
Filed: 1987-11-18
Abstract: PURPOSE:To prevent a printing wire from catching an ink ribbon and contrive a longer useful life and higher reliability of a printing head, by providing a contact member instantaneously displaced when the tension of the ink ribbon reaches or exceeds a predetermined value, on the upstream side of ribbon hauling-in rollers. CONSTITUTION:On the upstream side of ribbon hauling-in rollers 12, a leaf spring 26 makes contact with an ink ribbon 10. When a printing wire bites into the ink ribbon 10 during printing in the direction opposite to an arrow 13, the ribbon 10 is caught by the wire, and tends to be drawn out in the direction opposite to the feeding direction thereof, resulting in an increase in the tension on the ribbon 10. When the tension reaches or exceeds a predetermined value, the tip 31 of the spring 26 clears a projected part 34 into a recessed part 36, and is vibrated. At this moment, the tension acting on the ribbon 10 is quickly lowered (the two-dotted chain line condition), whereby the printing wire is released from the ribbon 10. Thereafter, the leaf spring 26 returns into an initial condition under the elastic restoring force thereof.

Title: Method for writing magnetic stripe data
Inventor: TAKAMURA SATOSHI
IPC: G11B20/10
Filed: 1993-11-24
Abstract: PURPOSE:To prevent the generation of a writing defect due to a writing current value deviated from an adequate range by a change in external environment, etc. CONSTITUTION:A control section 10 writes the writing current value as a min. and reads information when the section receives a writing instruction for magnetic stripe information. The control section receives the reproduced output voltage of the read information from a detecting circuit 24 and stores the voltage in a RAM 11. This voltage is compared with the original information. The writing is stopped after the writing is repeated until the writing current is maximized. The range where the normal writing is executed is detected from the information stored in the RAM 11. A response of writing infeasibility is emitted unless there is the adequate range. The range C2 where the change rate of the reproduced output voltage is small with respect to a change in the writing current is detected when there is the adequate range C1. The current value at the mid-point of the range C2 is determined as the writing current optimum value and is stored in the RAM 11. The writing is ended by emitting the normal response. The stable writing operation is executable by using the writing current optimum value stored in the RAM 11 in the subsequent writing.

IPC: H04B3/04
Filed: 1987-11-20
Abstract: PURPOSE:To effectively thin a reproducing signal waveform, to reduce asymmetry and to reduce a peak shifting by setting suitably an equalization constant while it is matched to a circuit characteristic applied. CONSTITUTION:A time difference between a peak point Pa of an input signal Sa and a maximum including point M1 is set as the delaying time of a delaying circuit 1 and a time difference between points M1 and M2 is set as the delaying time of a delaying circuit 4. The value is set in which the shape of the leading edge side and trailing edge side of an output signal Sd is symmetrical as the attenuation coefficient of attenuating circuits 5 and 6 and the excessive undershooting does not occur at the bottom part of the waveform of the signal Sd. Thus, when respective output signals Sa1, Sc1 and Sb2 of circuits 1, 5 and 6 are added by an adder circuit 7, the output signal Sd is obtained in which the half-value width of the waveform of the input signal Sa is thinned and the shape at the leading edge side and the trailing edge side is made symmetrical.
