Patent JP-H03100689-A (JP)
Title: Fixing device
Inventor: ISHIYAMA TATSUNORI
IPC: G03G15/20
Filed: 1989-09-14
Abstract: PURPOSE:To prevent electrical image disturbance generated in a fixing unit when fixing is performed by setting the longitudinal, highly insulating coating of a first roller longer than a part where the first roller comes into press-contact with a second roller. CONSTITUTION:For a fixing roller 1, a roller where a PFA heat shrinkable tube is fused on an aluminum pipe whose surface is treated with anodized aluminum is used. For a pressure roller 2, a material obtained by sticking silicone rubber to a stainless steel shaft is used. A coating layer 4 made of highly insulating material is provided on a part where the pressure roller 2 comes into contact with the fixing roller 1. The longitudinal coating layer 4 of the fixing roller 1 is made longer than a part where the roller 1 comes into press- contact with the roller 2. Thus, transfer charges on the surface of the pressure roller 2 never reach the side of the fixing roller 1 when the fixing is performed, thereby preventing electrical image disturbance.

IPC: G03F1/74
Filed: 1986-10-11
Abstract: PURPOSE:To correct a pinhole defect by applying an electron beam to a part wherein a pinhole exists, so as to melt gold in said part and thereby to fill up the pinhole. CONSTITUTION:An electron beam 16 is applied to a part wherein a pinhole 13 exists. In consideration that the melting point of gold is about 1000 deg.C, an electron beam of 20 KeV, 1 A/cm<2> formed in a 2-micron square was applied for 0.005 seconds. As the result, the gold in the 2-micron square was melted and the pinhole 13 was filled up completely therewith. Even when the pinhole is large, it can be corrected by scanning the aforesaid electron beam. This method can be implemented by using an electron beam apparatus which is employed in the present manufacturing process of semiconductor devices, and thereby a pinhole defect can be corrected more easily than by a usual chemical vapor growth method.

IPC: A62D101/22
Filed: 1995-09-19
Abstract: PROBLEM TO BE SOLVED: To provide a practical method which can render a PCB polluted object such as electric equipment having PCB adhering thereto harmless in safety. SOLUTION: In a non-toxication treatment of electric equipment, PCB is dried by evaporation with respect to a PCB-polluted object such as capacitor or transformer with a PCB insulation oil removed, after the drying thereof, the PCB-polluted object is disassembled and then, combustibles having the PCB adhering thereto is incinerated in an induction furnace 1 while metal undergoes a melting treatment and an exhaust gas containing the PCB generated during the drying and melting is subjected to a high temperature thermal decomposition treatment. A closed furnace lid 3 is arranged at an upper part of a furnace body and an internal pressure of the furnace is controlled by a negative pressure to prevent the leakage of a gas in the furnace through a clearance of a sealing part 9b.  Moreover, air or oxygen enriched air is blown into an upper space of an induction furnace 1 to burn the combustibles. Thus, the combustibles is heated through metal or melt metal receiving an induction heating thereby enabling incinerating of the combustibles by raising the temperature thereof.

Title: Dust cover
Inventor: TAKAHASHI KAZUTO
IPC: F16J3/04
Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To secure certain sealing and to improve sealability by arranging a plurality of projections, which are in contact with a wall surface, on a flange of a ferrule, in a circumferential direction with specified spacings. SOLUTION: A seal member 3 is arranged on a fitting portion of a ferrule 1, while a plurality of projections 4 are formed on an upper side of a flange 11 of the ferrule 1 in a circumferential direction with specified spacings. The ferrule 1 is to be attached to a ball stud and a knucle composing a member to be installed. At this time, the seal member 3 seals an outer periphery of a shaft of the ball stud, while the projections 4 are abutted against a wall surface of the knuckle. By sealing the outer periphery of the shaft of the ball stud by means of the seal member 3, entry of dusts and water is prevented from the gap between the flange 11 of the ferrule 1 and the-wall surface of the knuckle. It is also possible to prevent intrusion of dusts and water, as in case of a pinch bolt type, where a cutout for screwing the bolt reaches the ball stud.

Title: Diaphragm
Inventor: KITANO TAKASHI
IPC: B23K101/28
Filed: 1999-08-26
Abstract: PROBLEM TO BE SOLVED: To improve welding workability with a column member, and to enhance joining strength by forming a welding groove with the outer periphery of the column member on the inner peripheral edge of a ring-shaped joining member capable of being installed on the outer periphery of the column member, and arranging a flat part on this bottom surface. SOLUTION: Since a welding groove is formed in a straight line-shaped part on the inner peripheral edge of a joining member 12, a welding part 17 is executed only in a part for linearly opposing the outer periphery of a column member 11 and the inner periphery of the joining member 12 of a diaphragm 10. Opposed parts of an outer peripheral corner part of the column member 11 and an inner peripheral corner part of the joining member 12 are not welded to arrange a void. Since a flat part is arranged on a bottom surface of the welding groove, at welding, a welding arc sufficiently reaches up to the deep part so as not to cause a welding defect. Since a curved surface part is arranged on both end inner peripheral surfaces of the welding groove, welding metal sufficiently spreads to prevent the occurrence of a welding defect at the starting end and the trailing end of the welding part 17.
