Title: Airtight welded construction
Inventor: KOBAYASHI NOBUYUKI
IPC: B23K11/00
Filed: 1983-09-12
Abstract: PURPOSE:To prevent a defect such as an opened hole or the like by welding a disc provided with a small sized collar to an evacuating pipe and attaching the disc by resistance welding to the outside plate of a vacuum vessel thereby permitting easy surface treatment with the small part and enabling use of a thick material for the disc. CONSTITUTION:The outside plate of a vacuum vessel is drawn and a hole 1b for attaching a disc 3 is opened in a part thereof. On the other hand, an evacuating pipe 2 is inserted into the cylindrical collar 3a of the disc 3 and is brazed and united to one body. The surface is treated by pickling, etc. to remove thoroughly the scale and the pipe is airtightly attached by resistance welding to the hole 1b part of the outside plate 1. Since the resistance welding is accomplished under cooling by cooling water, the generation of oxide scale by local heating is obviated.

Title: Manufacturing method of resinoid offset type wheel and its mold
Inventor: MATSUMOTO TOSHIHIRO
IPC: B24D3/00
Filed: 1979-12-20
Abstract: PURPOSE: To obtain No.28 high quality offset type wheel without performing tooling work by premolding the external surface of No.27 offset type intermediate wheel on a taper surface when it is molded using a mold.  
     CONSTITUTION: When No.27 offset type intermediated wheel G 1  is formed using No.27 offset type intermediate mold A, a downward taper surface is formed on the wheel external molding surface 1b of a ring mold 1 and also on the external surface g 1  of the intermediate wheel G 1 . Then this intermediate wheel G 1  is pressurized, inserted, and sintered between No.28 offset type sintering plates 7 whose outer half part is inclined in the downward taper form. After sintered, it is removed from the sintering plate 7. This permits the external surface g 0  to be in parallel to the direction of an axis of revolution and the regular No.28 offset type finished wheel to be obtained. As a result, the high quality No.28 offset type wheel can be obtained without performing tooling work.

Filed: 1979-12-24
Abstract: PURPOSE:To prevent the damage of a tank by a method wherein an upper bottom plate is piled on a lower bottom plate fixed to the head of stakes, and the side wall of an outer concrete tank is rigidly attached to the upper bottom plate. CONSTITUTION:A structurally independent upper bottom plate 2a is laminated on a lower bottom plate 2b fixed to the head 1 of basic stakes, and the side wall 3 of an outer concrete tank is rigidly attached to the upper bottom plate 2a. By so doing, even if the external wall of the concrete tank is sharply cooled by the leaked low temperature liquid, causing internal shrinkage of the upper bottom plate 2a, no excessive stress occurs in the portion connecting the lower bottom plate 2b and the stakes 1 because shear strain is generated between the upper bottom plate 2a and the lower bottom plate 2b, thus preventing the damage of the tank.
