Title: Hinge for small-sized instrument and production method thereof
Inventor: KATAGIRI TAKASHI
IPC: E05D11/08
Filed: 1998-02-04
Abstract: PROBLEM TO BE SOLVED: To bring leaves to a stop at an arbitrary rotary angle by forming the inner diameter of both plastic leaves a little smaller than the diameter of a metallic pivot and making the inner diameters of the tubes of both leaves different from each other. SOLUTION: When both leaves 6, 8 are opened or closed, the leaf 8 having tubes 10, 10 with a smaller inner diameter rotates together with a pivot 14. The other leaf 6 having a tube 12 of the pivot with a larger inner diameter can not rotates together with the pivot 14 and the tube 12 of the leaf 6 rotates along the peripheral face of the pivot 14. As a result, the inner peripheral face of the tube 12 of the leaf 6 and the peripheral face of the pivot 14 serve as frictional faces to bring the leaf 6 or 8 to a stop at an arbitrary opening angle. The hinge 2 is attached to the connection parts of the cover and the body of a small wooden product with wooden screws. Hence, attachments such as a liquid crystal display or a lid in a small electronic instrument or a wooden product can be brought to a stop at an arbitrary opening angle.

Title: Laminated steel sheet for can
Inventor: KATO HIROYUKI
IPC: B32B15/09
Filed: 1993-02-26
Abstract: PURPOSE:To obtain a precoated steel sheet for a can wherein it is easy to weld and adhesion of a resin film is not deteriorated by retort treatment. CONSTITUTION:The steel sheet is obtained by laminating biaxially oriented polyethylene terephthalate resin to metallic chromium layer or a limited chromium plated layer of a chromium hydrated oxide layer or a plated steel sheet which possesse an Sn plated layer and a chromate layer on a chromium plated layer and has appropriate surface roughness by making use of an adhesive agent having limited favorable short time curing properties in a beltlike state by leaving a varnish guard part behind and hot-press-bonding polyethylene terephthalate resin containing appropriate quantity of isophthalic acid similarly to the laminated steel sheet and plated steel sheet. Thereby, since thermal shrinkage of a resin film is not generated even though weldability is secured, adhesion of the film is favorable and a problem of neither elution nor whitening is generated by retort treatment.

Title: Towing antenna
Inventor: TANAKA KATSUZO
IPC: B63C11/48
Filed: 1991-03-05
Abstract: PURPOSE:To prevent antenna wires from being tangled by providing a fixed wing to the left and the right of a shell able to be towed in water and providing a moving wing and a towing antenna wire to any of upper and lower ends. CONSTITUTION:Since a variable depth towing body 4 during its towing is controlled in a way that the left/right depth is constantly regulated and the attitude in water is kept horizontal by its own strength, the body is towed so that the distance between branch antennas 5, 6 is kept constant, in parallel and arranged horizontally. Thus, the vertical position of the antennas 5, 6 is unchanged and the entire depth is freely regulated. Fixed wings formed symmetrical to the left and right stabilizes shell roll and pitch and also yawing. The depth of the towing antennas 5, 6 in water is controlled by turning left and right wings simultaneously. When the one moving wing is turned upward and the other is turned downward, rolling is controlled. Thus, the antenna wires are towed from the position parted from the shell stabilized by the employment of both the fixed and moving wings to allow the antenna wires to keep a required interval horizontally at all times thereby avoiding the tangled or twisted antenna wires.

Filed: 1982-03-11
Abstract: PURPOSE:To make the in-band amplitude characteristic flat to improve the conversion precision, by using three acoustic surface wave dispersing delay lines different in delay characteristic to perform the Fourier transform of an input signal. CONSTITUTION:Pulses from an RF pulse generator 2 are applied to an acoustic surface wave dispersing delay line 1 having the characteristic, where the delay time is shortened linearly for the frequency, to obtain a chirp signal. A composite signal obtained by multiplying this chirp signal and a signal r(t) having  an unknown frequency spectrum in a multiplexer 3 is applied to an acoustic surface wave dispersing delay line 4 having the Characteristic where the delay  time is extended for the frequency. The output of this delay line 4 and a chirp  signal obtained in an acoustic surface wave dispersing delay line 5 having the  same characteristic as the delay line 1 are multiplied in a multiplexer 7 to  obtain a Fourier transform signal of the signal r(t). In this case, the width and  the carrier frequency of input pulses of the delay line 5 are controlled to eliminate the influence of the amplitude inclination of the delay line upon an output signal S(tau).
