Title: Method for nitriding metallic material
Inventor: KIUCHI MASAYUKI
IPC: C23C8/24
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To rapidly form a uniform nitrided layer on a metallic material at a low temp. by forming a dissociation gas from NH3 by means of an NH3 dissociation catalyst, carrying out heating in a nitriding atmosphere containing active oxygen, and forming a nitrided layer. SOLUTION: As the metallic material to be used, steel materials including carbon steel and stainless steel, Al materials, etc., are cited. As the NH3 dissociation catalyst, an Ni-type, ferrous, or Ru-type catalyst having dissociation power at <=500 deg.C is preferred. Particularly, in terms of low temp. activity, an NH3 dissociation catalyst in which Ru and alkali metal are supported on a carrier and halogen content is regulated to <=100 wt.ppm of the weight of catalyst can be suitably used. By utilizing such an NH3 dissociation catalyst, the control of the dissociation ratio of NH3 is made possible even in the case of a large gas-feed quantity causing no nonuniform nitriding, and nitriding can be performed rapidly at low temp. by accelerating the generation of active oxygen.

Title: Manufacture of contact material for vacuum valve
Inventor: OKUTOMI ISAO
IPC: H01H11/04
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To suppress generation of especially restrike of an arc in voltage resistant characteristics and to reduce the dispersion of a contact material by melting a conducting component containing Cu and an arc resistant component containing at least one of Cr, V, W, Mo, Ta, Nb, and Fe within the range of the melting point of both components, then casting. SOLUTION: A conducting component of a main contact material for constituting one or both contacts fixed to a moving electrode and a fixed electrode is preferably limited to 40-90 vol.%. Since the bonding strength between the conducting component and an arc resistant component is strong, irregularity formed by minor welding on the surface of the contact and release of fine particles caused by the local coming off of the arc resistant component are reduced, and restrike is suppressed. By the melting and casting both components, micro contact structure is formed and the dispersion of restrike generation is suppressed. Preferably, by using the arc resistant material having a mean particle size of 1-10 μm, uniform melting and distribution into the conducting component are obtained.  Adding of a low melting point element such as Bi, In, and Sn, and a light element such as B, C to the components is preferable.

Title: Observation device for weak luminous phenomenon
Inventor: TSUCHIYA YUTAKA
IPC: H01J31/50
Filed: 1982-09-28
Abstract: PURPOSE:To enable the picture signal of a streak image with a large S/N ratio to be obtained even if an object to be observed shows a weak luminous phenomenon, by superposing the streak image obtained by using a microchannel plate onto the fluorescent screen and by photoelectrically converting, namely, image- picking up the brightness on the obtained fluorescent screen. CONSTITUTION:A sweep voltage applied to a deflecting electrode 33 is synchronous with the output of a dye-laser oscillator 1, while said output is an exciting signal source which develops a fluorescent luminuos phenomenon. Consequently, the streak image of the fluorescent luminous phenomenon is repeatedly superposed and indicated on a certain part of a fluorescent screen 34. The coordinates of brightness and time are overlapped on the fluorescent screen 34 and indicated. For instance, when fluorescence excited with a dye-laser of repeated frequency of 100MHz is superposed for one second, the number of the superposed streak images becomes 10<8> and measurement of super weak light phenomenon such as producing one photon by 10<3>-10<4> times of excitation becomes possible. The streak image whose brightness is thus superposed and increased is picked up by a television camera 10.

Filed: 1985-07-31
Abstract: PURPOSE:To permit the automatic adjustment even if a divergence exists in press-contact position by setting the inside diameter of a through-hole formed onto a valve operating piece larger than the diameter of the leg part of a valve piece. CONSTITUTION:A through-hole 31 having the center of a valve seat 12 as center is formed onto a valve operating piece 15, and the inside diameter of the through-hole is formed a little larger than the diameter of the leg part 32 of a valve piece 16 inserted into said through-hole. The length L passing through the through-hole 31 of the leg part 32 is made a little larger than the thickness of the part forming the through-hole 31 of the valve operating piece 15, permitting the free sliding of the valve piece 16. The press-contact and separation of the valve piece 16 for the valve seat 12 are carried out through the swing or sliding of the valve operating piece 15. Therefore, even if a little divergence exists in assembly, fine valve closing operation is permitted by allowing the valve piece 16 slides the leg part 32 in the sliding hole 31.

Filed: 1988-07-06
Abstract: PURPOSE:To prevent the double operation of the period or month beginning processing in case two or more data processes are required within the same processing date by preparing a processing data information reading/writing part where the preceding processing date is replaced with the present processing data. CONSTITUTION:A present processing date information input part 1 is prepared together with a processing date information reading/writing part 2, an accounts period information reading part 3, an accounts moth confirming part 4, a period/ month beginning analyzing part 5, a processing date information storing part 6, and an accounts period information storing part 7. Then two types of information on the preceding and present processing dates are stored together with the accounts period information on each month beginning day. Thus it is possible to automatically decide the period or month beginning processing is required or not at execution of the data processes. As a result, the double operation can be avoided for the period and month beginning processes even in case two or more date processes are required within the same processing date in terms of the system operation.
