Patent JP-H08287782-A (JP)
Title: Rotary switch
Inventor: MARUHASHI TAKASHI
IPC: H01H21/28
Filed: 1995-04-13
Abstract: PURPOSE: To enhance the operational accuracy of a rotary switch by normally keeping the distance between a rotating contact piece and a fixed contact piece even when the stopping position of a driving body is dispersed and the driving body is excessively rotated. CONSTITUTION: When rotating force is applied to a driving body 8 through a driving part 16 from the outside, a rotor 5 united to a rotating contact piece 4 rotates by friction with the driving body 8. When the rotor 5 reaches a specified rotating position, the rotor 5 comes in contact with each of stoppers 6, 7 of a case 2. After that, when rotating force is applied to the driving body 8, a slip is generated against friction between the driving body 8 and the rotor 5, which are assembled by friction, and the driving body 8 continues rotation but the rotor 5 stops. Therefore, even when the stopping position of the driving body 8 is dispersed and the driving body 8 is excessively rotated, the rotor 5 stops in a specified rotating position. The contact/separation between the rotating contact piece 4 and a fixed contact piece 1 are normally operated.

Title: Radiation measuring apparatus
Inventor: WASHIO MASAKAZU
IPC: G01T1/02
Filed: 1989-05-01
Abstract: PURPOSE:To enable handy measurement of radiation by using deglycidyl ether of bisphenol A (DGEBA) as base material and deaminodephenyl methane (DDM) as hardening material to form a highly pure epoxy resin. CONSTITUTION:DGEBA is used as base material and DDM is added thereto as hardening material at a ratio of 1:1 to mix. When a mixture thus obtained is precured at 80-120, two components are arranged to perform a precrosslinking. Then, the mixture thus precured undergoes a main curing at 140-180 to obtain an epoxy resin with purity thereof exceeding 99%. The epoxy resin thus obtained is used to form a measuring body 1 to be set in a radiation irradiation area 20. The measuring body is irradiated with a light beam near 630 nm in wavelength from the light source 11 and light 15 which travels through the measuring body 1 and reflected with a metal mirror 13 is received with the measuring device 12. Thus, with the irradiation of radiation, the measuring body 1 has an increase in optical absorption near 630 nm and by detecting a decrease in an intensity of a reflected light 15, an intensity of radiation can be measured.

Title: Scanner operation supporting device
Inventor: TANAKA KAZUHIKO
IPC: H04N1/04
Filed: 1989-05-01
Abstract: PURPOSE:To determine the color sepn. conditions of a scanner in a short period of time without errors by determining the dot area rate of respective colors at which the hues of colors can be faithfully reproduced to some extent with ink of various colors in accordance with an exchange table. CONSTITUTION:Respective color density values of red, green and blue at the point where a color original 24 exists are measured and are inputted to an arithmetic processing section 10. The target dot per cent values of the dot per cent values of the respective colors for reproducing the hues of the colors at the point faithfully to some extent with the ink of the colors cyan, magenta, yellow, and black without deviating the hues are determined by computation using the exchange table. A display section 18 displays these values by the screen of, for example, a CRT or by printing onto a paper surface. The instructions of the target dot area rates of the respective colors is received by the displayed dot area rates of the respective colors in this way and, therefore, an operator is able to determine the color sepn. conditions of the scanner in a short period of time without errors and to rapidly set up the optimum color sepn. conditions.

Abstract: PURPOSE:To improve electrical properties of a transistor by a method wherein one conductivity type emitter region of high concentration formed in the opposite conductivity type base region of high concentration provided inside an opposite conductivity type epitaxial layer of low concentration and one conductivity type collector region formed adjacent to the base region in the epitaxial layer are provided. CONSTITUTION:An N<->-type epitaxial layer 12 is laminated on a P-type semiconductor substrate 16, and N-type impurities are selectively diffused into the epitaxial layer 12 to form a base region 13 high in concentration. P-type impurities are selectively diffused into the base region 13 to form an emitter region 14 of high impurity, a collector region 15 is formed adjacent to the base region 13 in the epitaxial layer 12, and P-type impurities are selectively diffused into the region 15 for the formation of a lead-out region 17 of high concentration. When the two-dimensional concentration of carriers is measured along certain regions, carriers in a collector region flow into a base region to make the base region non-uniform and gradient in carrier concentration, so that the base region becomes locally large and narrow in carrier concentration. In result, a transistor of this design can be enhanced in current amplification factor and improved in electrical properties.

Title: Grinding and molding apparatus and molded article produced therewith
Inventor: ASAO TAKUJI
IPC: C10L5/48
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To provide a grinding and molding apparatus for grinding and compression molding a raw material, such as rice husks, in one step and to provided a molded article produced therewith. SOLUTION: Rice husks are supplied through a supply port 38 to a port 28 and are thereby ground by the sliding between the projections formed on the inner surfaces of both a rotor 32 and a housing 30. The ground rice husks are conveyed through a discharge port 40 to a compression cavity 44 with a screw 36. Since the cross section of the compression cavity 44 is small relative to the amt. of ground rice husks discharged through the discharge port 40, the rice husks are compressed and bonded in the compression cavity 44. The bonded rice husks, having an expansion power, expand and are molded in a molding cavity 46 since the diameter of the molding cavity 46 is larger than that of the compression cavity 44. Since steam, which is generated by high temp. caused by compression, is discharged through grooves 48, 50 to the outside, the molded body is not deformed.  Thus, the grinding and molding of rice husks can be carried out in one step.

Filed: 1992-05-06
Abstract: PURPOSE:To facilitate high speed detection of welding error at a soldered part detecting oscillation noise through oscillation of printed circuit board on which parts are mounted, and compares the oscillation noised of normal soldered part and abnormal soldered part with each other. CONSTITUTION:A printed circuit board 2 is fixed on an oscillation part 1 and oscillated up and down.

It is thus possible to judge connection error at the soldered part by generating oscillation noise from the connection error part of solder 10 on the board 2, and detecting the minute noise by an oscillation noise detector 3 arranged on a matrix.
