Title: Polishing film cassette
Inventor: TAKAHATA TOSHIYA
IPC: B41J32/00
Filed: 1988-03-04
Abstract: PURPOSE:To polish a recording head at an arbitrary time by a slight amount of emery paper, by unevenly arranging a plurality of polishing films different in roughness to a polishing film. CONSTITUTION:A polishing film cassette consists of a polishing film 101, a cassette 102, a supply core 103 and a take-up core 104. When this polishing film cassette is inserted in a current supply thermal transfer type printer, a recording head is polished by lapping films 501, 502, 503 whose particle sizes are rough in this order. Thereafter, the polishing film cassette is taken out, and a cassette having an ink film mounted therein and image receiving paper are inserted in the printer and a recording signal is given to a recording head to perform printing. Since the polishing films different in a particle size are arranged as mentioned above to constitute the polishing film cassette, the amount of the polishing film necessary for polishing the head can be made slight and the time required in polishing can be shortened and the head can be polished at an arbitrary time and an image having high image quality can be always obtained.

Inventor: ISHIKAWA TAKATOSHI
IPC: H01R43/00
Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To provide a thermo-compression bonding method for connector in which elongation control of a resin film at the time of thermo-compression bonding can be properly performed to eliminate position displacement between a terminal on a substrate and a lead on a connector to the utmost and production yield can be improved. SOLUTION: A width size of a lead line 30a on a connector 12 is set to be shorter than a width size of a terminal line 31a on a substrate 11, size difference between both sizes is optically detected before thermo-compression bonding, and at least one of parameters of a pressurizing speed, thermo-compression bonding load, and bOnding time is changed based on data showing relation between each parameter and elongation of the connector 12, so the size difference is corrected by elongation in the width direction of the connector 12 in a thermo-compression bonding process. Since relation between each parameter and elongation quantity is correctly determined based on experimental data, the size difference can be properly corrected, thereby generation of defectives caused by position displacement of the thermo-compression bonding can be reduced to improve yield.

Filed: 1984-03-17
Abstract: PURPOSE:To improve the efficiency of suction supercharging at a low speed, high load range, by assisting the operation of a turbocharger by means of electrically operated motion of a reactance motor-generator. CONSTITUTION:At a medium- and high-speed range of an internal-combustion engine, a turbine impeller 5 rotates at high speed, and simultaneously with a suction supercharging quantity by a compressor impeller 4 becoming sufficient enough, an expanded diametral part 7 is driven as a generator rotor whereby voltage is induced in a stator coil 12, and the induced voltage is charged to a battery 19 through a voltage transducer 18. When the internal-combustion engine is operated at a low speed, high load range in times of starting and going uphill, a control circuit 14 feeds the stator coil 12 of a reactance motor-generator MG with suction supercharging on the basis of each output of a load sensor 15 and a suction pressure sensor 16. The reactance motor-generator MG operates as a mere motor, assisting a shaft having the expanded diametral part 7 becoming a rotor for its rotation, thus a suction supercharging quantity to a cylinder by a compressor impeller 5 is improved.

Filed: 1979-04-25
Abstract: PURPOSE:To prevent mutual interference between a trap circuit and a detecting circuit by connecting the second output circuit, the video detecting circuit and the sound intermediate frequency trap to the first output circuit of a video intermediate frequency amplifying circuit and a sound intermediate frequency detecting circuit. CONSTITUTION:Resistances 15 and 16 are connected to collectors of output transistors 11 and 12 of video intermediate frequency amplifying circuit 20 respectively, and this connection point is connected to not only sound intermediate frequency SIF trap circuit 22b provided outside amplifying circuit 20 but also video detecting circuit 23 inside amplifying circuit 20. Consequently, in respect to output transistors 11 and 12, the signal source impedance becomes high because collector outputs are adopted, and a sufficient trap level can be obtained even if the SIF trap circuit is connected in parallel. Since outputs are taken out from emitters and collectors of output transistors 11 and 12 respectively, mutual interference between two kinds of output is small.
