SOLUTION: End faces of metal tubes 1 and 2 are processed for protrusion and recess tapers, respectively, both of which are engaged by pinching an amorphous metal foil, and a heating site 4 in a limited range including a junction part 3 is heated by pressurization. The site 4 is surrounded by a work coil 5, and a cooling medium injector 6 is arranged between a site out of the site 4 of the sites surrounded by the coil 5 and the coil 5 and cooled by injecting a cooling medium such as water from plural ejection holes 7 peripherally of the metal tubes 1 and 2. A partition plate 8 is provided like a ring at the boundary between the heating site 4 and the cooling site so that the heating site 4 is never subject to cooling medium.  Consequently, the heating site 4 in the limited range in the lengthwise direction including the junction part 3 is selectively heated, and heating is restricted in a site out of the site 4.

Title: Data input/output device
Inventor: KANO SHUNSUKE
IPC: G06F3/00
Filed: 1987-09-17
Abstract: PURPOSE:To eliminate the need of special address setting to reduce misconnection by causing the order of positions, where data input/output devices are connected to correspond to chip select signals selected in a control unit. CONSTITUTION:When a CPU selects a chip select terminal CS2 at a logical low level, an input-side terminal CS2 and an output-side terminal CS1 of an input/output board 20 go to the logical low level. Numbers of terminals which go to the logical low level are change in each board hereafter, and an input-side terminal CS0 of a board 22 goes to the logical low level. When a read terminal RD of the CPU is set to the logical low level as the result, a NOR gate outputs a signal DELTAn a logical high level and data inputted from an external device and latched is sent to a data bus. Since correspondence relations between the connection order and terminals of the CPU are unequivocally determined in this manner, special address setting is unnecessary and misconnection is reduced.

Title: Method and device for purging back surface of substrate in chemical vapor processing
Inventor: DEATON PAUL
IPC: C23C16/44
Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To prevent formation of an unrequited deposit, by a method wherein there is provided a substantially annular opening giving a slit, and the slit is structured and disposed so as to direct a purge gas flow to a direction in substantial parallel to a plane defined by a wafer and outwardly of a radial direction from the slit. SOLUTION: If a surface 22 and a back surface 26 are rotated, this gives a movement amount outwardly of a radial direction to a reaction gas 18 and purge gas 32. A rotation speed is sufficiently increased and the gas is made to flow outwardly of a radial direction to a margin part 36 of a wafer 10 by mutual operations of the wafer surfaces 22, 26 and the gases 18, 32. This flow outwardly of a radial direction prevents the purge gas 32 and the reaction gas 18 from being remarkably mixed on an upper surface 22 of the wafer. A processing profile is accelerated so that it is made the most uniform outside a peripheral portion of the upper surface 22 of the wafer 10.

Title: Cover opening closing device
Inventor: TAO TSUNEO
IPC: F24C15/12
Filed: 1990-08-31
Abstract: PURPOSE:To eliminate a need for a force required for bending of an axle during insertion of the one end of the axle after the other end of the axle is inserted, to reduce deformation of the axle after mounting, and to improve appearance by a method wherein a helical part is formed in the middle of the axle to which a cover is pivotally supported. CONSTITUTION:The upper part of a device body 1 is covered with a jacket plate 2, and a cover 4 with which an opening 3 is covered, is attached to the opening 3. To provide a streamline forum, the peripheral edge of the jacket plate 2 and an peripheral edge part 5 of the cover 4 are both formed in a wide arcuate shape. A pair of bearing parts 6 are formed to respective end parts of the plane parts of the opening 3 and the cover 4, and an axle 8 in the middle of the linear part of which a helical part 9 is formed has both ends inserted through respective bearing part through-holes 7. During mounting of the axle 8, after the one end of the axle 8 is inserted in the bearing through-hole 7, during insertion of the other end, the axle 8 is easily bent at the helical part 7 and therefore simple mounting is carried out. In this case, a surplus load is not applied on the bearing parts 6 and deformation of the bearing part 6 is also prevented from occurring. Deformation of the axle during bending is easily restored through the spring property of the helical part 9, whereby a deformation of the axle 8 after mounting is extremely reduced and appearance is also improved.
