Title: Method for welding metallic members
Inventor: FUKAHORI MITSUGI
IPC: B23K26/21
Filed: 1992-12-17
Abstract: PURPOSE:To improve welding strength by welding flared fittings, then, pressing and abutting both flange parts to give compressive stress to the welded parts. CONSTITUTION:Metallic members 2, 2 are pressed and abutted by pressing rollers 13a, 13b to and on each other and a Joint surface part 4 of both members of the flare fitting 1 is irradiated with laser beam to weld both members. Both flange parts 3, 3 of the flare fitting l of the metallic members 2, 2 moved in a C-direction are bent by squeezing rollers 17, 17 and abutted on each other. Consequently, both flanges of the flare fitting are abutted on each other, the welded part makes a closed structure to the external part and though a stress acts to the direction separating two metallic members 2, 2 from each other, both members are not separated to improve fatigue strength. Further, for example, attachablility to a sealing member to seal this flare fitting is improved.

Inventor: SAKAMOTO MASANOBU
IPC: G02B26/10
Filed: 1990-11-30
Abstract: PURPOSE:To reduce wear of a dynamic pressure bearing and to reduce vibration of a device by composing a yoke for passing the magnetic flux of a permanent magnet to form a rotor so as to eliminate a magnetic attraction force in driving a polygonal mirror such as a light deflector of a laser printer. CONSTITUTION:The magnetic flux 21 from the N-pole of a permanent magnet 4 crosses an armature coil 6 to form a closed magnetic circuit through a yoke 5, the S-pole of the magnet 4 and the rotor 3 of a magnetic material. Here, since the yoke 5 and the magnet 4 are fixed to the rotor 3, a gap 22 is mechanically determined so as not to vary, and since the radial thickness of the yoke 2 is so determined that lines 21 of magnetic flux are not leaked out of the yoke 4, the influence of a magnetic attracting force of the magnet is not affected to a dynamic pressure bearing 8 provided on the outer periphery of the yoke 5, and the attracting force is not generated.

Title: Type/product number code reader
Inventor: KONDO KOJI
IPC: B65G47/49
Filed: 1989-12-28
Abstract: PURPOSE:To easily recognize type and product number codes visually and to read them with a comparatively simple device by providing a work on which the type/ product number codes consisting of a recessed part a projecting part is attached, and a type/product number code detecting means to read the recessed part or the projecting part. CONSTITUTION:The required number digits of a seven-segment mark 2 of numerical shape from 0 to 9 is attached on the work in recessed shape. The type/product number code reader 5 in which seven range sensors 3 are arranged at positions corresponding to each segment is arranged, and a range between the work 1 on which the seven- segment 2 is attached is measured in a still state. At this time, the output of the type/product number code reader 5 is issued when a range between the recessed part of the seven-segment 2 of the work 1 and the type/product number code reader 5 exceeds a prescribed value, and no output is issued when it is less than another pre scribed value, which enables a type and a product number to be identified. Thereby, since the type and product number codes can be easily discriminated with both a person and the type/product number code reader, a worker can perform working as confirming the type and the product number, and simultaneously, the management of the type and the product number can be performed mechanically.

Title: Optical transmission output alarm detection circuit
Inventor: ARATA KATSUTOSHI
IPC: H04B17/00
Filed: 1998-11-30
Abstract: PROBLEM TO BE SOLVED: To obtain an alarm detection circuit with high stability against fluctuation in ambient temperature and fluctuation in power supply voltage. SOLUTION: When an electric signal (a) from an input terminal 2 is interrupted, a voltage signal (b) that is an output of an amplifier 7 is interrupted and no voltage is applied to a capacitor 10. A peak voltage charged in the capacitor 10 is discharged by a time constant consisting of a capacitance of the capacitor 10 and a resistance of a resistor 13, then a stored voltage signal (d) is being decreased exponentially. When the voltage signal (d) reaches a preset threshold value (e) at an input terminal 14 or below, a comparator 15 outputs an alarm signal (f), which is informed externally via an output terminal 16. Since the same models are used for diodes 8, 9, the characteristic change due to fluctuation in ambient temperature and fluctuation in power supply voltage is the same for the diodes and no error is caused for an alarm detection time by the comparator 15.

Title: Heat insulating structural body, its manufacture, and hood-shaped member
Inventor: FUJIIKE SHIGERU
IPC: E04B1/80
Filed: 1998-11-30
Abstract: PROBLEM TO BE SOLVED: To provide techniques relating to a heat insulating structural body of high productivity such that demolding time can be reduced during production. SOLUTION: A heat insulating structure has a core 2 having a number of heat insulating foam resin chips and a polyurethane foam layer 3 covering a portion or the whole of the core 2.
