Title: Wiring pattern connecting structure
Inventor: TANAKA NOBUYUKI
IPC: H01L21/768
Filed: 1989-03-17
Abstract: PURPOSE:To contrive the long service life of a connecting element by making up the connecting part of vertical wiring patterns with a single through hole and causing its part to be formed into a plane shape in such a way that its width is substantially broadened stepwise in the direction of electron flow. CONSTITUTION:A connecting part 14 of vertical wiring patterns 10 and 11 is made up by a single through hole and its part is constructed to have a plane shape which is substantially broadened stepwise in the direction of electron flow e0. In other words, the plane shape of the connecting part 14 is substantially broadened in the direction of electron flow. Then, such a plane shape makes the length of a part where electron flow flows in the connecting part 14 longer. Consequently, the density of electron flow in the above part of the connecting part 14 is lowered and then, an advance of electromigration becomes harder. In such a case, when the supply of an electric current is kept on, disconnection in the connecting part 14 takes place at any rate. However, the time required for disconnection can be extended in comparison with conventional cases. The long service life of the connecting part 14 is thus obtained.

Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To adjust thickness and resistivity of an oxide film by heating a porous silicon carbide heater, which has a specified resistivity, in the atmospheric air at a specified temperature. SOLUTION: An organic foaming body is impregnated with the silicon carbide slurry, to which a boron compound is added, and the excessive slurry is eliminated, and temporarily sintered, and this temporarily sintered body is dipped in the silicon carbide slurry, to which the boron compound is added more, and the excessive slurry is eliminated, and sintered again so as to form a silicon carbide frame at 500-2000μm. In the stage of sintering, silicon carbide structure is grown thick. Resistance of the thick silicon carbide structure is low.  In this case, condition of a porous silicon carbide heater having a resistivity at 4-7Ωcm at 100 deg.C is fluctuated within a set temperature range set at 600-1400 deg.C in the atmospheric air, and finally, the surface of the silicon carbide structure is formed with an oxide film at 10-100μm, and a porous silicon carbide heater having a resistivity at 4-7Ωcm at 100 deg.C is obtained.

IPC: G06K7/10
Filed: 1990-03-17
Abstract: PURPOSE:To prolong an exchange period, that is, a virtual service life of a light source by controlling the turn-on of a bar-code reading light source only for a necessary period. CONSTITUTION:Under the control of an MPU 10, it is detected that an article goes in by a gate sensor article detecting part 11, and in accordance with this detection, a semiconductor laser (laser) being a bar-code reading light source is turned on by the ON control of a laser control part 12 and it is held for a prescribed time Ta. When a bar-code of the article is detected partially, a turn-on time of the laser is extended by a prescribed time Tb, and when demodulation of the bar-code is completed within the turn-on time Tb of the laser which is extended, the laser is turned off quickly, and when it is not completed, the laser is turned off at the time of time-over. In such a way, since the bar-code reading laser is subjected to turn-on control only for a necessary period, the change period, that is, a virtual service life can be extended.

Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To connect conductors, without taking account of the shorting with contacts holding a PTC element by bending bus bar ends to form contacts and offsetting the contacts to electrically connect them each other through this element. SOLUTION: A conductor connection 1 with a PTC element 30 is composed of a pair of bus bars 10, 20 which are punched metal plate-like conductors bent at the ends 11, 21 and housed in an electric connection box when being used. The connection 1 is such that the bus bar ends 11, 21 are bent to form contacts 11a, 11b, 21a, which are offset and electrically connected each other through the element 30. Owing to the offsetting of the contacts, if a very thin PTC element is used, the connection can be made, without taking account of the shorting due to the mutual touch of the contacts.

Title: Laser beam welding method
Inventor: SATO KENICHI
IPC: B23K26/14
Filed: 1994-03-10
Abstract: PURPOSE:To provide the laser beam welding method capable of butt welding in high speed. CONSTITUTION:By irradiating a high temp. plasma gas flow from a plasma torch 3, a wide molten pool is formed on the surface of plate stocks 1, 2 to be welded which are in an irradiating region. Further, by the laser beam irradiated to the position offset backward than the center C in the traveling direction of the irradiated region, a plasma is newly generated in a plasma gas atmosphere due to the plasma torch 3. Thus, when a traveling speed is set to high speed, by the plasma generated based on simultaneous irradiation of laser beam, the discontinuously of plasma arc is supplemented so as to stabilize arc discharge, a plasma arc anode point of the plate stocks 1, 2 to be welded is smoothly traveled. Accordingly, there is no case that a plasma input heat quantity for the plate stocks 1, 2 to be welded is short and the fusion due to Joule heat is turned to be discontinuous so as not to generate lack of fusion by laser beam.
