Title: Ink jet recorder
Inventor: KAWAKUBO TOSHIO
IPC: B41J15/04
Filed: 1980-10-16
Abstract: PURPOSE: To provide an ink jet recorder which is equipped with a paper holding device wherein balls are held to be freely rotatable in plural ball holders which are installed to the carriage of recorder and balls are lightly pressed and caused to make point contact with the surface of a sheet of recording paper and by this the sheet of paper is prevented from being deviated since balls are also freely movable along a platen without deforming the paper.  
     CONSTITUTION: A holder plate 12 is fixed to the end of a carriage 4 and guide members 13 1 W13 3  are installed to the holder plate. A ball holder body 14 is installed to the guide member 13 so that it can be freely moved back and forth in relation to a platen 1 and the holder body 14 is applied with slight force by a coil spring 15 and the holder body 14 is caused to hold a steel ball 16 to be freely rotatable, for instance 3 steel balls 16 1 W16 3  are arranged so that they are constantly pressed against a sheet of recording paper 2 at such positions away from a surface of printing. In both cases when the carriage moves in the direction of A and the platen 1 rotates to feed the recording paper 2, 3 steel balls 16 1 W16 3  freely rotate and lightly hold the recording paper by point contact.  
     EFFECT: The recording paper is not scratched and scanning load is not large.

Title: Piston for internal combustion engine and its manufacture
Inventor: KURITA HIROTAKA
IPC: B21J5/00
Filed: 1997-06-03
Abstract: PROBLEM TO BE SOLVED: To improve the mutual joining strength of a head part and a skirt part in a piston having the mutual joining interface of members of different kinds, by forming the joining interface into a recessed shape or a projected shape which is not flat, and arranging a stretching texture in at least one member in the recessed part or the projected part of the joining interface. SOLUTION: An alloy 51 for a head part, formed of quenched powder aluminum alloy is arranged lower, an alloy 50 for a skirt part, which is formed of aluminum, silicon, copper and so on, is arranged upper, and they are overlapped, then stored in the recessed part 56 of a lower die 55 preheated, and after that, they are pressurized by a punch 57 so as to be forged into a piston shape. At this time, while the piston 57 is formed in a manner that necessary thickness is applied to each of parts of a piston 58, a recess 59 is formed in the central part of the bottom surface of the recessed part 56 of the lower die 55 by being opposed to the projected part 57a of the punch 57.  Then, stretching textures are produced in parts 200b and 200c so that the parts 200b and 200c can be joined with each other without fusing the joining interface by hot-forging using these lower die 55 and punch 57, thereby the piston 58 is formed with high accuracy.

Title: Biaxially stretched polyester film for magnetic tape
Inventor: IWASAKI YUJI
IPC: G11B5/73
Filed: 1988-06-13
Abstract: PURPOSE:To lower the thermal shrinkage rate after working to a magnetic tape by using a certain specific biaxially stretched polyester film. CONSTITUTION:The thermal shrinkage rate in the machine direction after treatment for 30 minutes at 80 deg.C is <=0.1% and the DELTAnMD defined by the equation I is >=0.100. In the equation, nMD, nTD and nTH respectively denote the refractive indices in the machine direction, transverse direction and thickness direction of the film. The thermal shrinkage rate after working to the magnetic tape is undesirable even if the DELTAnMD is >=0.100 if the thermal shrinkage rate exceeds 0.1%. Elongation arises in the traveling direction of the film in the stage of working to the film and the thermal shrinkage rate is degraded if the DELTAnMD is <0.100. The thermal shrinkage rate is preferably <=0.08% and the DELTAnMD is preferably >=0.105, more preferably >=0.110. The tape having the excellent dimensional stability after working to the magnetic tape is improved in this way.

Title: Electronic copying machine
Inventor: YOSHINO TAKAO
IPC: G03G15/20
Filed: 1979-11-09
Abstract: PURPOSE: To effectively execute the fixing treatment of a copying paper which is thick and small-sized, and also prevent generating fire at the time of an operation error, by controlling so that the copying paper is stopped once in the fixing device, and also maintaining the fixing vessel at low temperature while it is stopped.  
     CONSTITUTION: When the thick paper copy switch 29 is operated, the power supply conducting angle to the fixing heater 197 is controlled by the fixing heater control circuit 107 through the microprocessor 171, etc., and the fixing device becomes high temperature as specified. And, when the tip of the copying paper which has been conveyed into the fixing device is detected by the paper detection switch 157, the solenoid 181 is excited, and in case when the copying paper is thick and it is detected by the paper size timer that the paper is of the same small size as a postcard, the copying paper is stopped. At the same time, after the prescribed time has passed, the solenoid 181 is demagnetized, the power supply conducting angle of the heater 197 is controlled until the copying paper is conveyed again, and the fixing device is controlled so as to be at low temp. Accordingly, a copying paper which is thick  and small-sized is brought to the fixing treatment effectively by a little power consumption, and even if thin paper is treated by the thick paper mode, fire is not caused.

Title: Current injection type logical gate circuit using josephson effect
Inventor: SONE JIYUNICHI
IPC: H01L39/22
Filed: 1981-09-14
Abstract: PURPOSE:To attain the miniaturization, high degree of integration and high speed of a logical circuit, by constituting a current injection type OR gate circuit containing no inductance just with resistances and Josephson junctions. CONSTITUTION:As shown in the diagram, a logical gate is provided with 3 Josephson junctions 30-32 and resistors 33-36. When an input current Ia or Ib is injected to the logical gate while a gate current Ig is flowed, these input currents flow to an earth through the junctions 32 and 30. Thus the junction 30 is switched to a resistance state. A part of the current flowing to the junction 30 flows to the resistor 36 via the junction 32, and the other part of the current flows to the junction 31 through the resistors 30-35. Thus the junction 31 is switched to the resistance state. As a result, a part of Ig flows to a load resistance 41 and the rest of the Ig flows to the resistor 36 through the junction 32. At the same time, a patt of the input current flows to a load resistance 41 through the junction 32. Thus the junction 32 is also switched to a resistance state.

Title: Automatic sensitivity calibrating device
Inventor: HAYASHI HIDENORI
IPC: G01D3/024
Filed: 1982-08-20
Abstract: PURPOSE:To calibrate automatically the sensitivity with high reliability, by multiplying a counter output value, which is inreased or reduced in accordance with the result of the comparison between the output value for the input of a calibrating reference signal and a reference output value, by the output of a measuring amplifier. CONSTITUTION:When a sensitivity calibrating command signal is inputted, an FF5 is set, and a switch 13 is turned on, and a calibrating reference input is inputted from a voltage generator 14 to a measuring amplifier 1. An output a' is obtained as an output voltage E0 through a multiplying D/A converter 2. The voltage E0 is compared with a reference value Es in a comparator 3, and contents of a counter 4 are increased or reduced in accordance with the result of the comparison. Since the output of the counter 4 is outputted to the D/A converter 2, the output E0 coincides with the reference value Es. When they coincide with each other, the comparator 3 is inverted, and the FF5 is reset, thus terinating the calibration. Thus, the manual work is unnecessary, and the reliability is improved because there are no movable parts.
