Title: Surface mounted component and correction of soldering
IPC: H05K1/18
Filed: 1992-03-27
Abstract: PURPOSE:To make it possible to correct a poorly soldered terminal which has occurred in a surface mounted component without the use of a retaining jig and causing other terminals to be deformed by bending upwards the tip end of a terminal that extends past a portion thereof to be soldered and also by forming in such a manner that the tip end is located at a position where it can be seen from above. CONSTITUTION:A lower terminal 3 is formed by bending the tip end thereof upwards and laterally displacing it such that the tip end is situated at a gap between upper terminals 2. The formation of the structure of the terminal 3 in this manner allows the soldering of the terminal 3 to be individually corrected without deforming the upper terminal 2 or removing solder 5. Also, in order to make it possible to solder a terminal without a presser jig, a soldering gun is used for the correction of the soldering of the terminal 3, wherein the gun is arranged such that the fusion of solder due to heating, and the solidification of the solder caused by heat dissipation are carried out while the terminal is maintained in a held state by pressing the up-directed tip end of the terminal with a recessed portion of the end of the gun. This method can be applied to the soldering of fine divisions, and also renders an auxiliary jig for retaining a terminal when it is soldered unnecessary.

Abstract: PURPOSE:To prevent any fracture of bonded end surfaces by providing a small radius at the center of each bonded end surface, which is formed into a V-shaped cross section, of insulating tube pieces in an upper side while a large radius in a lower side, to bond the pieces to each other. CONSTITUTION:Insulating tube pieces 1, which have been baked already, are bonded to each other with glaze 2 for assembling, and are baked in a furnace, thereby obtaining a long and large insulating tube. The bonded end surface of each insulating tube piece 1 is formed into a V-shaped cross section. A load applied to the insulating tube pieces 1 in an upper side is small while a load applied to the insulating tube pieces 1 in a lower side is large. Accordingly, radiuses R1, R2 of the pieces 1 in the upper side are small while radiuses R3, R4 of the pieces 1 in the lower side is large, thus alleviating a stress concentrated on tip ends of the V-shaped cross sections. Therefore, the insulating tube pieces 1 in the upper side can be positioned accurately, and any fracture of the bonded end surfaces of the pieces 1 in the lower side can be prevented.

IPC: H01L21/28
Filed: 1988-03-25
Abstract: PURPOSE:To form a fine wiring pattern having high dimensional accuracy by applying a metallic film onto a thin wiring pattern formed by processing a thin conductive film applied onto the surface of a wafer by using a photoresist and by etching through a CVD method. CONSTITUTION:A thin conductive film 3 is applied onto the surface of a wafer 1, and a thin wiring pattern 4 is formed by processing the conductive film 3 by a photoresist and etching. A wiring in specified film thickness is formed by applying a metallic film 5 onto the thin wiring pattern 4 through a selective CVD method. That is, shape is easily controlled by etching while displacement (dimensional shift) from the size of the resist is reduced because the film thickness of the conductive film 3 is thinned, and the film thickness of the wiring can be thickened as the dimensional accuracy of the wiring is left as it is kept because no resist mask is used when the metallic film 5 is applied onto such a thin wiring pattern 4. Accordingly, the fine wiring having high dimensional accuracy can be formed.

Title: Automatic bath boiler
Inventor: NOGUCHI YUKINOBU
IPC: F24H1/46
Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To prevent a bather from being displeased by water circulation by a pump by a method wherein water supply is prohibited in a normal state during hot keeping operation, and is permitted when the set temperature is lowered. SOLUTION: When a hot-keeping mode instruction issued from a remote controller, a water supply flag fa is set at 0 to indicate the prohibited state. Therefore, automatic water supply is prohibited in principal during hot-keeping mode (60). When an instruction to lower the set temperature Ts is output (61), the water supply flag fa is set at 1 to indicate the permitted state (62), and enters a standby state until a hot-keeping timer, that controls intervals during hot-keeping mode, runs out (63). When the hot-keeping timer runs out, a water supply routine takes place (65). The water supply routine starts after it is confirmed that the water supply flag fa is set at the permitted state. When the water supply routine comes to end, the water supply flag fa returns to 0 of the prohibited state and the hot-keeping timer is reset.
