Title: Drive circuit of light emitting diode
Inventor: YAMASHITA KIICHI
IPC: H01L33/00
Filed: 1984-08-31
Abstract: PURPOSE:To shorten the falling time without loss of the rising time of an LED by connecting an impedance circuit between the collector and the emitter of a drive transistor and between the emitter and the ground terminals. CONSTITUTION:An impedance circuit 101 connected between the collector and the emitter of a drive transistor 1 is a series circuit of a resistor 11 and a capacity 12, and an impedance circuit 102 connected between the emitter and the ground terminal is formed of a resistor 13. When an input pulse signal is transferred from H to L levels, the emitter potential of the transistor 1 is dropped simultaneously in response to the base potential since the emitter potential of the transistor 1 is substantially constant at the voltage between the base and the emitter. On the other hand, the collector potential abruptly rises since the collector current does not flow to an LD2, and a voltage across the circuit 101 abruptly increases. Accordingly, charge is quickly charged in the capacity 12. This charging current is supplied by the discharge of the charge stored in the parasitic capacity of the LED2, the falling time of the LED2 is largely improved.

Title: Apparatus for developing thermal pressure-sensitive paper
Inventor: ISAKI TAKESHI
IPC: B41J2/475
Filed: 1986-07-31
Abstract: PURPOSE:To prevent the generation of wrinkles, damage and development irregularity on the surface of paper, by constituting the title apparatus so that a large number of short magnetic rods are arranged to a gap where an alternating field is generated and impact can be applied to the surface of thermal pressure-sensitive paper passing through the gap by the magnetical reversal force of the short magnetic rods. CONSTITUTION:An iron block 1 is formed into an almost annular shape having a gap on one side thereof and a large number of short magnetic rods 5 having a small diameter are allowed to fill the gap. A current is allowed to flow to a coil 3 when thermal pressure-sensitive paper P passes through the gap by a feed roller 6 to form an alternating magnetic circuit in the iron block 1 and an alternating field is generated between both magnetic poles opposed across the gap. Therefore, short magnetic rods 5 are magnetized to be attracted to each other. However, the direction of a magnetic field becomes reverse by the alternating field and the microcapsule on the surface of the thermal pressure-sensitive paper receives impact to be destructed by the repetition of the reversal motion of the short magnetic rods to perform development treatment and the generation of wrinkles, damage and surface gloss or development irregularity on the surface of the paper is eliminated.

Title: Transmission control system for data
Inventor: UDAGAWA TERUO
IPC: H04L29/06
Filed: 1989-07-13
Abstract: PURPOSE:To avoid missing of information by controlling dynamically the transmission interval in response to a reception data number per unit time and increasing transmission information quantity of one transmission when lots of transmission data are generated. CONSTITUTION:A reception data inputted asynchronously to a counter means 101 is counted for reception data number per unit time and fed to a transmission interval decision means 102. The transmission interval decision means 102 calculates the value of a load state and decides the transmission interval of the reception data by a transmission means 103 depending whether or not the value is a prescribed value or over. When the load state value is a prescribed value or over, plural reception data inputted during the transmission interval is stored tentatively in the transmission means 103 and plural reception data are sent altogether after the elapse of the transmission interval. Thus, the loss of information when the reception data per unit time is much or deterioration of relay performance is avoided.
