Title: Connector
Inventor: TAKEKIDA YOSHISUKE
IPC: H01R13/04
Filed: 1977-12-28
Abstract: PURPOSE: To simplify structure as well as raise the coefficient of friction for holding pin by giving an elasticity to produce contacting force by the procedure in which contact pin is prepared by molding a mixture consisting primarily of carbon fiber as the main component and a rubber or a synthetic resin.  
     CONSTITUTION: The connector consists of the signal lead plate 2, the  connector contact 3 attached on the end portion of the signal lead plate 2, made by molding a mixture of carbon fiber and a rubber, etc., and the printed board 1. The receiving of signal is made between the contactor 3 and the printed board 1. And, the insulating rubber 4 is provided between the connector contactor 3 made by molding carbon fiber and rubber. Thus, a stable elasticity is produced by the connector contactor 3 and the insulating rubber 4, whereby the coefficient of friction is raised and thus the printed board is stabilized to an extent that more or less vibration is absorbed, permitting the stable receiving of signal due to good conductivity of carbon fiber.

Title: Pulse driver circuit
Inventor: WATANABE KAZUHIKO
IPC: H03K17/60
Filed: 1977-12-28
Abstract: PURPOSE:To shorten an accumulation time simply and economically by interposing an accumulated-charge absorption circuit composed of a transistor and diode between the base and emitter of a switching transistor. CONSTITUTION:When a pulse of waveform 1 is applied to point (a) at the secondary side of pulse transformer 1, a voltage current of waveforms 2 and 3 is generated at the base of switching transistor (Tr)7 via reverse-current preventive diode 4 and a collector current of waveform 4 starts flowing. At this time, accumulated- charge absorbing Tr3 is OFF and base resistance 2 operates to adjust the impedance at the secondary side of transformer 1 in this state. Although a reverse voltage of waveform 1 is developed at point (a) when a pulse at point (a) is OFF, Tr3 turns ON to absorb an excessive voltage stored in the base of Tr7. Then, (ts) and (ts') of waveform 2 show the comparison between the insertion of accumulated-charge absorption circuit 5 and non-insersion. Consequently, the number of parts is small and the circuit constitution is simple, so that this circuit will suit to high-density packing.

IPC: B41J2/375
Filed: 1986-07-08
Abstract: PURPOSE:To prevent a thermal head from being over-energized, by shortening an energization time for the thermal head according to the total number of dots printed. CONSTITUTION:Table (A) is used to obtain the degree of effect represented by the intersection of a printing period and the number of dots printed. The degree of effect thus obtained is made to be the total number of dots printed. Table (B) is used to obtain a correction value of energization time represented by the intersection of the printing period and temperature. Table (C) is used to obtain the energization time for the second line represented by the intersection of the printing period and the temperature, and the correction value is subtracted from the energization time thus obtained, thereby obtaining an optimum energization time. A thermal head is controlled based on the optimum energization time, in printing the second line. This processing is performed for each line, whereby the thermal head can be prevented from being over- energized.

Title: Speed change gear of electromotive rotary tool
Inventor: KISHI ICHIROU
IPC: B23B45/00
Filed: 1981-10-05
Abstract: PURPOSE:To realize not only certain switching but also switching during rotation of the captioned device. CONSTITUTION:Recessed parts 61a-61c are formed where projections of a sliding key 39 are engaged with outer side faces of a pair of speed change gears 55, 56 arranged in parallel with a shaft 35, while a pair of projections with an interval longer than the longitudinal length occupied by the speed change gear 55 is formed on the sliding key 39. When said key 39 is slid in one direction, one projection is engaged with a recessed part of the opposite speed change gear 55, while the other projection is separated from the opposite speed change gear so that its certain switching is possible instead of being put in locked condition. Further, since a condition is available where the sliding key 39 is engaged with neither projection, switching is possible during rotation.

Title: Printing plate takeout device
Inventor: OKUTSU KOICHI
IPC: G03F7/20
Filed: 1993-06-29
Abstract: PURPOSE:To prevent dust and dirt in the air from adhering to a printing plate of uppermost layer. CONSTITUTION:Suckers 408 and 420 are disposed on the sucker supporting frame 410 of a PS plate takeout unit 402, and a PS plate 18 laminated on a placing table 32 are sucked and raised by the suckers 408 and 420, thereby successively taking out the PS plate 18 of the upper most layer from the placing table 32. A cover plate 80 having a size little larger than the size of the PS plate 18 is attached to the upper surface side of the frame 410, and a drop curtain 82 is attached to the circumference of the cover plate 80. When work for taking out the PS plate 18 is stopped, the frame 410 descends and stands by in a state where the suckers 408 and 420 are proximate to the PS plate 18 of the upper most layer. Therefore, a space between the upper surface side of the PS plate 18 of the uppermost layer and the frame 410 is partitioned from the circumference by the cover plate 80 and the curtain 82, thereby preventing the dust and the dirt suspending in the ambient air from adhering to the upper surface of the PS plate 18 of the uppermost layer.

Abstract: PURPOSE:To make an interface between a semiconductor layer and a gate insulating film good and to stabilize a characteristic by a method wherein, after the gate insulating film is formed on the insulating layer, a laser is irradiated and a silicon oxide film is produced at the interface between the semiconductor layer and the gate insulating film. CONSTITUTION:A gate insulating film 4 composed of an oxide insulator is deposited on a semiconductor layer 2 and on an ohmic contact layer 3 which have been formed on an insulating substrate 1. Then, the gate insulating film 3 is irradiated with an excimer laser A; the semiconductor layer 2 absorbs the laser beam and is heated up to a temperature of 1400 deg.C or higher; a silicon oxide film 5 is produced at the interface between the semiconductor layer 2 and the gate insulating film 4 by a reaction of silicon in the semiconductor layer 2 with oxygen in the gate insulating film 4. At this time, this assembly is cooled gradually after the laser has been irradiated; both the semiconductor layer 2 and the ohmic contact layer 3 which are formed of amorphous silicon are changed to polysilicon. Consequently, a thin-film transistor which is manufactured finally becomes a transistor whose operating speed is high.
