Title: Paper feeder
Inventor: OZAWA HIROOMI
IPC: B65H23/192
Filed: 1980-05-30
Abstract: PURPOSE: To prevent papers against damages caused by the cycle lag of feeding in a paper feeder of a laser beam printer by detecting the moving position of a buffer plate for controlling the rotation of a heat roller.  
     CONSTITUTION: Laser beam is patterned by an AC modulator 2 and the surface of a sensitive drum 5 is exposed. Paper 17 is sent to a heat roller 14 and a back-up roller 15 for fixing by a tractor 8 via a buffer plate 11 which absorbs the cycle lag. In this kind of device, when a cycle lag is given over an amount absorbable by the buffer plate 11, the paper 17 is broken. To prevent this breaking, the moving position of the buffer plate 11 is detected by an encoder plate 21 and a photoelectric element, and the heat roller 14 and the back-up roller 15 are controlled for their rotation through a logical circuit. This construction can prevent the cycle lag.

Abstract: PURPOSE:To make it hard to cause dislocation and dehydration of solute and to fully ensure reliability in a high temperature atmosphere by dissolving tetraalkyl ammonium salt or tetraalkyl phosphonium acid salt of furan dicarboxyl acid having gamma-butylolactone as a main solution. CONSTITUTION:This electrolyte is composed of gamma-butylolactone as a solvent, 2,5-furan dicarboxyl acid tetramethyl ammonium or 3,4-furan dicarboxyl acid tetramethyl ammonium as solute. This electrolyte solution is used to impregnate a capacitor element. The electrolyte capacitor using this electrolyte solution has no problem for any characteristics even in a high temperature atmosphere for a long time. Further, since blending with another solute is allowed, a blending quantity is optional in the range not exceeding satulation concentration, however, no effect can be obtained in the case of less than 3g to a blending solvent 100g, while in the case of exceeding 30g, deposition of solute is observed. This electrolyte solution exhibits high reliability in a high temperature atmosphere.

Title: Nozzle for arc spot welding
Inventor: KOGA AKIO
IPC: B23K9/29
Filed: 1986-03-31
Abstract: PURPOSE:To improve a welding efficiency by providing the notch part having a notch face on the lower part of a cylindrical nozzle and by arranging a compressed air exhaust port on the notch face. CONSTITUTION:A notch part 1 is provided on the lower part of a heat resistant cylindrical nozzle 4 and composed of a notch face 5 and sweepback face 7 as well. In this case, the notch face 5 is continuously formed in the tangent line direction on the peripheral face of the nozzle 4 and the sweep back face 7 has the sweepback angle which is from the tangent line face. A groove 2 for compressed gaseous body and blowing port 9 are communicated by opening a compressed gaseous body exhaust nozzle 8 on the notch face 5. The molten metal to be discharged from the notch part 1 is instantaneously cooled and the generation of the excess metal part of the above of the upper plate stock 12 can be prevented because of the gas flowing with its turning from a shielding gas through hole 3 being exhausted from the notch part 1 and a compressed airstream being exhausted from the exhaust nozzle 8. In this way the efficiency in welding can be improved.

Abstract: PURPOSE:To attain high speed switching and to prevent an electrostatic induction type transistor(SIT) from being broken due to short by SEPP-connecting switching transistors(TRs) and applying switching power only by the ON operation of the TR. CONSTITUTION:The driving TRs Q51, Q52 are SEPP-connected and pulses with mutually reverse phases are inputted to the TR Q51, Q52 through a driving transformer T51 based on a signal pulse generated from a power supply 51 to mutually switch the TRs Q51, Q52. On the other hand, outputs are extracted from the source-drain common terminals of the TRs Q51, Q52 and driving power supplies E52, E53 are connected so as to turn on/off the SIT. Even it a signal pulse is interrupted or the TR Q51 is broken and short is continued, the SIT can be prevented from being broken due to the short by impressing a negative voltage to the gate of the SIT.

IPC: H04B7/26
Filed: 1986-03-31
Abstract: PURPOSE:To simplify installation work and to facilitate maintenance and inspection and its movement by connecting a master station and plural relay stations by a wired transmission line and connecting the relay stations and a terminal equipment (mobile station) with radio communication using a weak radio wave whose electric field intonsity is limited to a prescribed value or less. CONSTITUTION:In sending data from a terminal equipment 81 to the master stationl, a radio equipment 61 using a weak radio wave calls a relay station 4 located nearby to send the data. The relay station 4, based on the received data, operates an exchange 3 via a relay station control section 41 to call the master station 1. The master station 1 connects the line via a master station control section 2 depending on the call from the relay station. The relay station by the connection of the line sends the data sent form the radio equipment 61 to the master station 1 through the relay station control section 41 and the exchange 3. On the other hand, after the master station 1 receives the data, the line of the sections 41, 2 is interrupted and the state is restored to the standby state and the master station control section 2 transfers the data to the master station 1. The master station 1 uses the operation processing unit 11 or the like to apply required data processing.
