Title: Method and device for diagnosing insulation of electric equipment
Inventor: OKITSU HIROTO
IPC: G01R31/12
Filed: 1987-01-16
Abstract: PURPOSE:To easily diagnose the degree of insulation deterioration of electric equipment with high accuracy by finding an electrostatic capacity increase rate or insulation deterioration constant, and comparing this with a criterion or dielectric strength statistical data and diagnosing the degree of insulation deterioration. CONSTITUTION:When a specific voltage is applied to the electric equipment from a power source part 11, a sensor 12 detects a leak current. An insulation constant arithmetic means 13 finds the electrostatic capacity and dielectric loss rate of the ground insulator of the electric equipment from variation o a leak current signal. Those values are sent to an insulation deterioration constant arithmetic means 14. A characteristic arithmetic constant with which insulation constitution is reflected is inputted previously to the means 14 from a various constant input circuit 15. The means 14 uses inputs from the means 13 and circuit 15 to find the electrostatic capacity increase rate or/and insulation deterioration constant. Those values are sent to a quality decision circuit 16 and compared with plural criteria indicating the respective degrees of insulation deterioration to diagnose the degree of insulation deterioration, and the diagnostic result is displayed on a display part 17. The insulation deterioration constant is displayed on a display part 18.

Title: Optical multiplex communication equipment for automobile
Inventor: KIMURA YOSHIHIKO
IPC: H04B10/00
Filed: 1984-01-19
Abstract: PURPOSE:To decrease the loss of an optical signal and also its manufacture cost by connecting a part of a steering column of an optical multiplex communication equipment for automobile and a part of the steering wheel by means of one optical slip ring. CONSTITUTION:Each light wavelength is lighted by applying the light from a power supply 11 to light sources 51, 52, 53 via an electric slip ring 14. When light shield parts 41-43 are in proper switching state to the light sources 51-53, the transmission/interruption of each light of wavelengths lambda1-lambda3 is selected and a prescribed signal state is generated. The optical signal obtained in such a way is subject to wave synthesizing and multiplexing by a synthesizer 3, transmitted to photodetectors 91-93 and also to a branching filter 8 in a control unit 7 via an optical slip ring 1 and processed by a signal processing circuit. Since the light sources 51-53 are provided to the turning part of the steering wheel in such a way, the provision of one optical slip ring is enough for connecting each optical system of the turning part and fixed part.

Title: Fillet mig arc welding method of aluminum thin plate t shape joint
Inventor: SAGAWA TAKAHIRO
IPC: B23K9/02
Filed: 1996-01-22
Abstract: PROBLEM TO BE SOLVED: To obtain a fillet welded bead having stable penetration by specifying wire diameter and welding speed, in the fillet welding of an aluminum thin plate. SOLUTION: This welding method is the one, in which a T shaped joint constituted with the thin plate having <=2mm thickness, composed of the aluminum or its alloy is joined by the fillet welding having <=3mm leg length with MIG welding. In this execution, the welding wire having <=1.2mm diameter is used and the welding speed is necessary to be 180-350cm/min. In the case of exceeding 1.2mm wire diameter, the arc stability at the low welding current value is deteriorated. Further, in order to obtain such small leg as <=3mm, it is necessary to concentrate the arc to a bevel corner part, and, in the case of exceeding 1.2mm wire diameter, the arc is spread and the shortage of penetration is developed. As for the welding speed, in the case of being less than the above lower limit, the welding current value is lowered too much and the shortage of the penetration is developed.  Reversely, in the case of exceeding the above upper limit, the arc force becomes too much and the defective welding, such as undercut, is developed.

IPC: G01M11/00
Filed: 1985-01-21
Abstract: PURPOSE:To make possible the quick analysis of the compsn. of an object to be measured with high accuracy while preventing the deterioration thereof by applying white X-rays to plural single crystals, taking out plural monochromatic X-rays, irradiating the same to the object and using the monochromatic X-rays having high energy. CONSTITUTION:The X-rays are emitted from an X-ray generator 1 and are throttled by collimators 3, 4. The X-rays are made into the monochromatic X-ray by the diffraction satisfying a Laue condition with the single crystal 7. The X-ray is made into the monochromatic X-ray by the diffraction satisfying a Bragg condition with the single crystals 8, 9. These monochromatic X-rays are irradiated to the object 11 to be measured which is a base material for an optical fiber consisting of, for example, silicon oxide and germanium oxide. The object 11 is moved in the direction perpendicular to the optical axis of the monochromatic X-rays and is thereby scanned. The transmitted X-rays are detected by a detector 2. Since the monochromatic X-rays are irradiated to the object, the quantity of the irradiation light is decreased and the deterioration of the object is prevented. The analysis of the compsn. with high accuracy is made possible as there is no influence of the pulse spread.

Abstract: PROBLEM TO BE SOLVED: To provide a product agreeable to the touch and providing an absorptive article wearer with a sense of relief through deodorizing effect without providing the wearer with an unhygienic feeling by mixing activated carbon in a humor absorptive article to effectively deodorize malodor components produced from humors and discharges. SOLUTION: A humor absorbing layer 12 is formed between a back face sheet 11 and a water permeable surface sheet 10, and a deodorant comprising activated carbon 15 is arranged on the surface sheet 10 side of the absorbing layer 12 to form this humor absorptive article. Malodor components produced from humors and discharges can therefore be effectively deodorized, and the activated carbon is arranged on the surface sheet side of the absorptive article. The contact ratio between the malodor components and activated carbon is therefore heightened to sufficiently exhibit the deodorizing effect of the activated carbon, thus attaining positive deodorization.
