Title: Degreasing/burning implement for aluminum nitride molded form
Inventor: WATANABE SHOJIRO
IPC: C04B35/638
Filed: 1998-10-14
Abstract: PROBLEM TO BE SOLVED: To provide the subject implement in the form of a boron nitride sintered plate with porous structure having each specific porosity, flexural strength and air permeability coefficient and enabling through operation to burning process including uniform degreasing step. SOLUTION: This degreasing/burning implement is made of boron nitride sintered compact in the form of a porous hexagonal sintered plate, having a porosity of 40-60 vol.%, flexural strength of >=20 MPa, air permeability coefficient of 1.1 to 2.0×1.0-9 mol.m/m2.s.Pa, and the average pore size of its through hole of pref. <=1 μm. The porous hexagonal sintered plate is produced by the following process: hexagonal boron nitride set in order with an average particle size of <=10 μm, oxygen content of 1.5-3 wt.% and boron oxide content of <=0.3 wt.% is molded under a molding pressure so as to afford the porosity of the final sintered compact to a specified value and then burned at 1,800-2,300 deg.C in an inert atmosphere under normal pressures.  The porous hexagonal sintered plate thus obtained can be used as this degreasing/burning implement for large-sized/thick-walled aluminum nitride molded forms which prevents to-be- burnt objects from cracking and enables the binder in such objects to be subjected to uniform decomposition/elimination treatment.

IPC: H02M7/5387
Filed: 1988-11-18
Abstract: PURPOSE:To enable following a high frequency by allotting a high frequency PWM signal to FET and a low frequency power-frequency signal to a bipolar transistor. CONSTITUTION:The output of a sine-wave generator circuit 22 is made into a rectangular wave by a rectangular-wave generator circuit 23, accordingly the output is positive or negative, to become signals phi1, phi2 to drive bipolar transistors 1, 2. On the other hand, the absolute value of the output of the sine-wave generator circuit 22 is taken via an absolute value circuit 25 and compared with the absolute value of the output of a triangular wave generator circuit 24 by a comparator 27 to form a PWM signal. The PWM signal becomes signals phi3, phi4 via a drive signal supply circuit 28 to drive FET transistors 9, 10. Thus, a low frequency component is controlled by the bipolar transistors 1, 2 and a high frequency component, by the FET transistors 9, 10.

Title: Explosionproof insulation tube and bushing using the same
Inventor: SAKAMOTO KENICHI
IPC: H01B17/36
Filed: 1995-11-10
Abstract: PROBLEM TO BE SOLVED: To easily adjust a dimension of an insulating tube even if dispersion exists in a dimension of hollow porcelain, and prevent scattering of a broken piece by dividing the insulating tube into plural parts in the axial direction, and integrally joining the respective divided parts together by a joining part having an axial directional length adjusting function in an explosion proof insulator and a bushing using the same. SOLUTION: Inside of a ceramic tube 1, an FRP-made insulating tube 12 is composed of plural split parts 12a and 12b divided in the axial direction, and they are integrally joined by a joining part 13. A screw assembling structure can be adopted as the joining part 13. In this case, in a screw thread part, since a thickness reduces and strength reduces, it is desirable that a screw thread shape is rounded and shallowed like a base of an electric lamp and reduction in strength is restrained to the minimum extent. When the joining part 13 of this type is used, a dimension of the whole insulating cylinder 3 can be easily adjusted by changing a screwing-in quantity. The joining part 13 becomes an electrically slightly weaker point than the other part of an insulating cylinder 3.  Therefore, it is desirable that the joining part 13 is arranged in a position not less than 1/3 of hollow porcelain from the lower end of the hollow porcelain 1. This is because a part up to 1/3 from the lower end of the hollow porcelain 1 is large in a concentration degree of an electric field and there is the possibility of generating internal discharge or the like when the joining part 13 is arranged in this position.

Title: Method and apparatus for cleaning substrate
Inventor: MORINISHI TAKEYA
IPC: B08B1/04
Filed: 1998-10-15
Abstract: PROBLEM TO BE SOLVED: To clean the whole surface of a substrate uniformly by making a cleaning tool follow the vertical vibration of the substrate promptly. SOLUTION: While a substrate W is being rotated, a treating liquid is ejected toward the substrate W from a treating liquid ejection hole 13 in the bottom surface of a cleaning tool 5, and the substrate W is vacuum-sucked from a vacuum suction hole 8. By the balance between the ejection force and vacuum suction force of the treating liquid, a narrow clearance G is formed between the bottom surface of the cleaning tool 5 and the surface of the substrate W. The substrate W is cleaned by making the cleaning tool 5 act on the surface of the substrate W through the liquid film of the treating liquid existing in the clearance G. When the substrate is vibrated vertically while being rotated, the cleaning tool 5 is moved vertically to follow it to keep the clearance G constant so that the whole surface of the substrate is cleaned uniformly.

Title: Method and device for detecting coming-off of power source plug
Inventor: ONODA HAJIME
IPC: G01R31/02
Filed: 1989-11-14
Abstract: PURPOSE:To detect the power source plug coming off a power source outlet by monitoring the impedance obtained by viewing the power source plug side from the power source line connected to the power source plug. CONSTITUTION:Many AC outlets are connected to interior wiring and various electric equipments are connected in parallel through those outlets. Then the impedance when exterior wiring is viewed from the interior wiring is equal to the secondary-side impedance of a pole mounted transformer, so the impedance is extremely small. Therefore, when the AC plug 1 of an equipment is connected correctly to an AC outlet, the impedance when the side of the plug 1 is viewed from power lines 2a and 2b in the equipment is the sum of the power input impedance of all the equipments connected to the interior wiring and the impedance of the exterior facilities regardless of power feeding and a power failure and extremely small, but when the plug 1 is pulled out of the outlet, the impedance obtained by viewing the side of the plug 1 becomes extremely large. The variation in impedance like this is used to detect the coming-off of the plug.
