Title: ARC WELDING METHOD OF Al BASE PLATED STEEL SHEET
Inventor: OIKAWA HATSUHIKO
IPC: B23K9/16
Filed: 1998-12-15
Abstract: PROBLEM TO BE SOLVED: To prevent the coarsening of crystal grain and to obtain a joining part excellent in joined strength, closeness and corrosion resistance by using CO2 gas or mixed gas of Ar and CO2 as shield gas and executing MIG welding or MAG welding. SOLUTION: Steel plates to be welded, applied with Al base plating, are lapped and a fillet welding to this lapped portion on is executed with a welding torch. As the shield gas at the welding time, CO2 gas is used. Further, as the shield gas at the MAG welding time, the mixed gas of Ar and CO2 is used. As the shield gas, it can be used to either gas, but in order to reduce the spatter as less as possible, the mixed gas of Ar and CO2 is better to use than CO2 gas. Further, in the mixed gas of Ar and CO2, the composition between both is particularly no problem but Ar gas mixing CO2 gas in 10-30% is desirable for stabilizing the arc and reducing the spatter.

Title: Thermal head
Inventor: ITO TOMOKAZU
IPC: H05F1/02
Filed: 1991-12-21
Abstract: PURPOSE:To prevent accumulation of static electricity generated by a side contact of a substrate surface with a printing medium to smoothly feed the printing medium by a method wherein a destaticizing conductive film is formed also in grooves provided on the substrate surface in the vicinity of the end of a heating element array. CONSTITUTION:On a substrate 1 of a thermal head, grooves 6 are formed at the end of a heating part (a), i.e., a raised part. A conductive film 5 is provided also in the grooves 6 similarly to the other surface of the substrate 1. Before a protective film 4 and the conductive film 5 are provided, grooves 6a are formed on a common electrode 3c in the vicinity of the end of a heating element array in a feed direction X by etching because a heating point-free part takes the from of the grooves 6. By providing the grooves 6 on the surface conductive film 5 in this manner, a conductive film 5b in the grooves 6 remains if a repeat of printing results in the wear of a conductive film 5a on the top of the raised part coming into contact with a printing medium 7. Thus, electrostatic charges generated at a conductive film 5c on the top end of the substrate by the slide contact thereof with the printing medium 7 are not accumulated but grounded through the conductive film 5b. In addition, the contact of the printing medium 7 with the conductive film 5b discharges the charges accumulated on the printing medium 7.

Abstract: PROBLEM TO BE SOLVED: To provide a single wafer processing cleaner capable of washing by ultrasonic vibration additionally to chemical washing by a chemical agent and moreover preventing oxidation of a substrate by outside air and contamination of the substrate with dust and impurities at the time of washing. SOLUTION: In the state that a shielding plate 12 and a container 11 are joined, a space between the shielding plate 12 and a substrate housed in the inside of the container 11 is filled with a washing liquid. An ultrasonic vibrator 17 is installed in the shielding plate 12 and the ultrasonic vibration radiated by the ultrasonic vibrator 17 is transmitted through the washing liquid and reaches the substrate 10. Consequently, additionally to chemical washing by a chemical washing liquid, washing by ultrasonic vibration can be carried out.  Moreover, since the space between the shielding plate 12 and the substrate 10 is filled with the washing liquid, the substrate 10 is prevented from coming into contact with outside air and from being oxidized and mist adsorbing dust in the outside air and splashes taking in impurities and rebounding from the floor face and the wall faces of the case housing the cleaner are prevented from adhering to the substrate 10.

Abstract: PURPOSE:To prevent the occurrence of blocking phenomenon when a plurality of containers are stacked up by a method wherein the upper and lower end parts of a number of the protrusions of a heat insulating sheet cover are differed in height. CONSTITUTION:A heat insulating container is formed such that a surface heat insulating sheet cover 2 on which a number of long protrusions 3 are successively formed longitudinally of the peripheral wall of a container is stuck on the outer surface of the peripheral wall of a container body 1 made of a paper on which water resisting processing is applied. In the heat insulating container, each protrusion 3 of the surface heat insulating sheet cover 2 has an upper end part 4 positioned on the upper side of the container and a lower end part 5 positioned on the lower part side thereof. The surface of the protrusion 3 is protruded in a state that it is inclined based on the base sheet surface of the surface heat insulating sheet cover 2 so that the height of the upper end part 4 is increased to a value higher than that of the lower end part 5. When a plurality of container 1 are stacked, only the lower end part of the protrusion is brought into contact with the inner surface of the container 1 at a subsequent lower stage, and this constitution prevents the occurrence of blocking phenomenon.
