Title: Straightening method for steel sheet by linear heating
Inventor: ISHIMARU YASUO
IPC: B21D1/06
Filed: 1977-09-21
Abstract: PURPOSE: To automate the straightening work through effectively giving the tension, by quickly heating and cooling linear portion of the steel sheet depending on  the thermal conduction within a narrow range, employing the input-heat-controllable- plasma-flame as the heat source, and by giving the internal buckling to the steel  sheet according to the thermal expansion, so as to generate a tension after cooling.  
     CONSTITUTION: The plasma flame 6 linearly heats the steel sheet 1; this linear heating limited so as to make the width of heat distribution in the direction of breadth to be 2W4 times of sheet thickness (b); hereby, the temperature difference due to thermal conduction in the direction of thickness (b) is made as small as possible; the heating of the steel sheet is carried out under these conditions of heat input as stated here. Besides, the internal buckling is given to the sheet without causing the external buckling; the steel sheet just after heating is quickly cooled by water of a very little quantity, or a naturally cooled in the air. The steel sheet 1 as the outer shell of the vehicle structure can be adequately tensioned by heating in whichever direction of longitude or traverse, however, the simultaneous heating in both directions give much more effect. Since the heating is carried out so as not to cause the buckling deformation in the outer shell 1, the outer shell does not need restraint, so that the baking, the tensioning, and the straightening can be effectively carried out on the outer shell 1.

Title: Image recording device
Inventor: SHIMAMURA KAZUHIRO
IPC: B65H23/18
Filed: 1986-05-16
Abstract: PURPOSE:To control the paper feeding speed always constant even if the diameter of a feeding roller or a taking-up roller varies, by directly detecting the paper feeding speed of an image recording device which uses a recording paper in roll form and controlling a motor for feeding paper by the above-described detection signal. CONSTITUTION:When a motor 14 for supply, motor 15 for driving roller and a taking-up motor 16 are operated, these motors 14, 15, and 16 revolve in the direction of arrow A, and a recording paper 2 is driven out from the recording paper roll 1 of a recording paper feeding means 3, and travels in the direction of arrow B, and is taken up onto the taking-up roller 6 of a recording paper taking-up means 7. During the continuation of the recording operation, the diameter of the feeding roller 1 reduces, and the diameter of the taking-up roller 6 increases. The tension applied onto the recording paper in traveling is varied by the variation of the diameter of the roller, and the paper feeding speed varies. Since the paper feeding speed is always monitored by a speed detecting means 18, the variation of the paper feeding speed is detected by a speed detecting means 18, and the paper feeding speed can be kept constant by the feeding motor 14.

Title: Hydraulic device having tandem pump
Inventor: NAKAMURA KYOICHI
IPC: F04C11/00
Filed: 1986-05-16
Abstract: PURPOSE:To prevent the occurrence of cavitation, by a method wherein a suction pipe running from a reservoir to a vane pump is branched into plural parts, return pipes from a fluid pressure device are joined together to form a one-piece pipe, and the tip thereof is caused to face on the outflow port of the reservoir. CONSTITUTION:When a car engine E started, vane pumps Pa and Pb suck fluid from a reservoir T, and the fluid is fed to a power steering device A and a fan drive hydraulic motor B. The return flows of pressure fluid, by means of which a given work is effected with the aid of a hydraulic responding device, are joined approximately in the same direction at an Y-shaped joining pipe. Therefore, speed energy is synergistically increased and outputted with a force through a return pipe 40d, and thereby fluid around an outflow port 23 is sucked in a suction pipe 20b through the roll-in action of the return flow to exert a more powerful supercharge action. Since the fluid is smoothly and uniformly branched through a Y-shaped branch pipe 20a, insufficient suction is prevents from occurring to a vane pump.

Title: Thin film magnetic head
Inventor: NAITOU TSUTOMU
IPC: G11B5/31
Filed: 1984-06-01
Abstract: PURPOSE:To solve problems such as the wear and plastic flow of a thin film magnetic head owing to traveling of a magnetic medium and to produce a thin film magnetic head having a long life by using a magnetic metallic material having high hardness on the traveling surface of the recording medium consisting of the thin magnetic metallic film. CONSTITUTION:The thin film magnetic head is constituted by using an amorphous alloy or Fe-Al-Si alloy to the lower thin magnetic metallic film 2 and an Fe-Al-Si alloy for the central rear thin magnetic metallic film 5. The thin film magnetic head made into such constitution permits the formation of the Fe-Al-Si alloy and amorphous alloy, etc. having high hardness into 1-2mum thin film and the working of the film by lift off and ion etching. The Fe-Ni alloy which is easily electrodepositable is laminated on the part of the recording medium except the traveling surface in order to prevent the magnetic flux saturation of the thin magnetic metallic film which is formed as thinly as 1-2mum. The stable thin film magnetic recording and reproduction are thus made possible with the decreased frictional deterioration in traveling of the medium.

Title: Power amplifier
Inventor: KANAI TAKASHI
IPC: H03F3/20
Filed: 1980-08-19
Abstract: PURPOSE:To achive a noncutoff type power amplifying circuit, by flowing a constant current to a resistor and producing a bias voltage of transistors (TR) at output stage with the voltage drop. CONSTITUTION:At no signal, constant current flows to resistors 43, 45 from a constant voltage source 31 and this voltage drop biases TRs 6, 7 and 8, 9. When a positive input signal is applied, the TRs turn on, and an output current flows to an output terminal 12 via a resistor 10. Since a voltage produced across the resistor 10 is given to resistors 39, 42, the current through the resistor 43 is reduced by the current flowing to the resistor 42 and a potential difference between connecting points P and Q is increased. Thus, the cutoff of the TRs 8, 9 is avoided. When a negative input signal is applied, the potential difference between the P and Q is extended to avoid the cutoff of the TRs 6 and 7.

Title: Air separator
Inventor: NAKAMURA HIROHIKO
IPC: F25J3/04
Filed: 1989-05-08
Abstract: PURPOSE:To improve the fractionating efficiency of oxygen gas by a method wherein the heated-air discharged from a turbine compressor is caused to exchange heat with the liquid air at the bottom of the lower tower of a fractionator and cooled heated-air and the liquid air heated and vaporized after that exchanging are returned to the upper tower of the fractionator and the lower tower of the fractionator respectively. CONSTITUTION:By a newly installed heat exchanger 24 the heated-air discharged from a turbine compressor 18 is caused to exchange heat with the liquid air at the bottom of the lower tower 6 of a fractionator. A part of the liquid air vaporized after heat exchanging with the heated-air discharged from the compressor 18 rises up together with the feedstock air supplied to the bottom of the tower 6 and they exchange heat with the liquid air at a condenser 32 installed at the top of the tower 6. The oxygen vaporized at the condenser 32 becomes a rising gas and rises up in the upper tower 13 of the fractionator. Consequently, the rising gases at the tower 6 and the bottom of the tower 13 are increased by the amount of the vaporized gas generated at the bottom of the tower 6. That is, a reflux flow rate is increased and fractionating efficiency is improved.

Title: Cross-flow fan
Inventor: NAKAMURA KUNIO
IPC: F04D17/04
Filed: 1983-06-23
Abstract: PURPOSE:To enhance the efficiency of a cross-flow fan, by providing a member for controlling forced vortice created in the cross-flow fan, in the discharge area thereof in the vicinity of the outer peripheral surface of an impeller. CONSTITUTION:Of circulating streams created in an impeller 1 and having forced vortice, the stream V remote from the center of the vortice is restrained from radially enlarging due to the presence of a vortex control member 6. Meanwhile, due to the insertion of the vortex control member 6 the power of the vortice may be increased, and the through-stream lines f1, f2, f3 may be extended horizontally on the suction side. Accordingly, the cascade work is increased, resulting in that pressure characteristic is enhanced. It is noted here that the insertion point of the control member 6 is limited to the range where no through-stream is directly affected.
