Title: Vacuum interrupter
Inventor: NODA TAIJI
IPC: H01H33/664
Filed: 1988-06-06
Abstract: PURPOSE:To improve the interrupting performance and the possible number of interruption, by making the width of a spiral groove in a part of annular contact portion of a spiral electrode less than that in the other part. CONSTITUTION:In an annular contact portion 14 at the central region of a spiral electrode 11, and in a portion near the inner end of a groove 12a formed in an arcing part 3 in the peripheral region of the contact portion 14, there is formed a groove 12b having a width smaller than that in the other portion. Accordingly, the groove width at the contact portion 14 is small, but the arc energy at the contact portion 14 is small too, so that the inner end of the groove can be made to be the electrode center side with almost no lowering of the intensity. Thus, the interrupting performance and the possible number of interruption can be improved simultaneously.

Title: Apparatus for measuring optical density
Inventor: OZAWA KENJI
IPC: G01N21/27
Filed: 1985-06-24
Abstract: PURPOSE:To make it possible to perform measurement by arbitrarily selecting a three- point simultaneous measuring mode and a one-point simultaneous measuring mode, by using two kinds of dichroic mirrors and two reflective mirrors so as to make said mirrors accessible to the optical systems of three measuring heads. CONSTITUTION:Red, green and blue signals outputted from measuring heads 20, 30, 40 are sent to an operation part 57 and respectively converted to density values to be displayed on a display part 58. The red component of the light incident to the head 30 is reflected by a red reflecting dichroic mirror 50 to be directed to the optical system of the head 30. The light in the other wavelength region transmits through said mirror 50 to be incident to a blue reflecting dichroic mirror 51. Because this mirror 51 reflects blue light toward the optical system of the head 40, the light of the remaining wavelength region transmits said mirror 51. The light transmitted through the mirror 51 reaches a green filter 35 where only green light is taken out to be incident to a light receiver 36. The red light reflected from the mirror 50 is directed to a light receiver 26 by a reflective mirror 52 and reflected to receive photoelectric conversion. Further, the blue light reflected from the mirror 51 is directed to a light receiver 46 by a reflective mirror 53 and reflected to be photoelectrically converted.

Title: Carbon material for electrode
Inventor: USHIZAWA NORIHIKO
IPC: C01B31/04
Filed: 1993-06-10
Abstract: PURPOSE:To obtain a strong and easy-to-machine carbon material for electrode having high film adhesion properties by making it contain a specific quantity or more of carbon where graphite occupies a specific quantity or more of the carbon. CONSTITUTION:A lead wire 2 is connected to one end face 1a of a carbon 1 and they are insulated with an insulating material 3. Subsequently, a film 4 exhibiting oxidation and reduction functions is formed on the other end face 1b of the carbon mainly by electrolytic oxidation polymerization. The material to be employed contains 99.0wt.% or more carbon where graphite occupies 50wt% or more of the carbon. When the graphite is contained less than 50wt%, adhesion properties of polymer film and organic film are deteriorated. When the content of carbon is less than 99.0wt%, impurities in the carbon cause deterioration of the characteristics of a sensor employing such carbon material. Since a thin carbon wire is obtained, various sensors can be miniaturized thus allowing measurement of small quantity specimen or implantation measurement to be realized.

Title: Transistor ignition device for engine
Inventor: SOTOZAKI MORIYOSHI
IPC: F02P1/08
Filed: 1979-10-25
Abstract: PURPOSE:To spoil an operation of a transistor when a running speed of an engine stands over a certain level and prevent an overrunning by providing a time constant circuit for a thyristor which is turned on by applying a positive voltage of an AC generator to turn the transistor on. CONSTITUTION:A time constant circuit 8 which holds for a certain period an on condition of a thyristor (SCR)4 after activated is connected between a gate and a cathode of the SCR4 in a transistor ignition device having no signal coil. When a running speed of an engine rises over a certain level, a charging voltage of a capacitor 10 in the time constant circuit is reduced. As a positive voltage from an AC generator 1 is raised before the SCR4 is biased off, on the condition of the SCR4 is held until the positive voltage is approximately zero. During the on condition, a Tr3 does not execute an ignition behavior. Thereby, an overrunning may be prevented without providing an overrunning preventive thyristor.

IPC: H01S3/042
Filed: 1992-05-29
Abstract: PURPOSE:To obtain a solid laser device which does not generate any temperature distribution in a solid laser medium even if a temperature difference is produced in a refrigerant by reducing the channel sectional area of a region cooling the solid laser medium at a downstream side as compared with that at an upstream side. CONSTITUTION:A surface of transparent screening plates 140a and 140b opposing lamps 12a and 12b is nearly in parallel with the surface of a YAG slab laser medium 11 and that opposing the surface of a medium 11 is inclined so that the thickness is increased from an upstream side toward a downstream side. Then, the channel sectional area of a region cooling the medium 11 of a refrigerant circulation path 16 is reduced at the downstream side and a cooling water is delivered from a refrigerant delivery port 160b through a channel which is formed by the rear and front surfaces of the medium 11 and the transparent screening plates 140a and 140b. Therefore, when the ratio of sectional area between the upstream and downstream sides is set properly, the amount of cooling can be made equal at the upstream and downstream sides, thus cooling the solid laser medium without generating a non-uniform temperature distribution.

Title: Chip type fuse resistor

Filed: 1998-05-21
Abstract: PROBLEM TO BE SOLVED: To provide a chip type fuse resistor wherein, with simple structure and less processes, a stable anti-surge characteristics against a fusing characteristics is provided, and no fuming or combustion takes place even at heating under abnormal excessive load, with wide freedom in complete resistance value. SOLUTION: Resistance film R and a protective film 4 are formed by thick- film grazing with an area resistance value of a central part R1 of the resistance film R higher than an area resistance value of a both end parts R2 while a direction turning point 3' and an end point 3" of a trimming groove 3 applied to the resistance film R are positioned at both end parts R2. Since a softening- point temperature of the glass component of the protective film 4 is lower than that of the glass component of the central part R1, the joule heat caused by an excessive current at abnormal excessive load is concentrated on the central part R1, and the heat melts the protective film 4 and then the central part R1. The flow and dispersion of glass components due to the melting cut off a circuit.
