Title: Method for preventing hydrogen embrittlement after plating
Inventor: KIIRI HIROSHI
IPC: C25D5/50
Filed: 1989-03-31
Abstract: PURPOSE:To easily remove gaseous hydrogen contained in a plating film and blank in a short time in an automatic plating line by heat-treating the plated blank in vapor satd. with a fluorine-contg. inert substance. CONSTITUTION:When a plating film of a metal is formed on blank in a plating stage in an automatic plating line and immediately gaseous hydrogen contained in the plating film and the blank is removed in a heat treating stage, the plated blank is heat-treated for several min in a vapor phase satd. with a fluorine- contg. inert substance. Since the inert substance has superior heat conductivity and very low surface tension, the plating film and the blank can be heated in a short time and the contained gaseous hydrogen can be removed in a short time.

Title: Driver circuit for load
Inventor: HIGUCHI YOSHIKAZU
IPC: H02P29/02
Filed: 1988-04-06
Abstract: PURPOSE:To prevent a malfunction due to welding of a contact by stopping a load driver circuit once and obviating restart when the contact supplying load with power is not opened. CONSTITUTION:When a starting switch S is closed, relays R1, R2 are driven by auxiliary contacts R3b, R4b. Main relays R3, R4 are driven respectively by auxiliary contacts R1a2, R2a2, and main contacts R3a, R4a and the auxiliary contacts R3b, R4b are operated. When the main contact R3a is welded, a power supply is interrupted by the pairing main contact R4a. When the starting switch S is closed again as the contact is left as it is welded, the relays R1, R2 are not driven because the auxiliary contacts are brought to an open state, thus preventing the supply of a DC motor 3 with the power supply.

Title: Method of removing org. film
Inventor: KADOMURA SHINGO
IPC: H01L21/302
Filed: 1999-03-26
Abstract: PROBLEM TO BE SOLVED: To easily remove an org. film by producing radicals in an F-based gas and removing the org. film i.e., an org. low-dielectric const. film formed on a laminate, using the radicals. SOLUTION: An org. film 4 formed on an org. low-dielectric const. insulation film 3b as a resist mask is removed by radicals produced in an F-based gas and then by radicals produced in an ammonia-based gas. The org. film 4 is etched by a high frequency induction coupled plasma generator, i.e., ICP generator and removed from the org. low-dielectric const. insulation film 3b. Because of a low reactivity of the radicals with the org. low-dielectric const. insulation film 3b, the org. low-dielectric const. insulation film 3b is not removed. This eliminates the trouble of etching the org. low-dielectric const. insulation film 3b.

Abstract: PROBLEM TO BE SOLVED: To promote withstand voltage performance of a power board by providing rectangular shutter boards equipped with flaps along either one of a pair of ends on long sides. SOLUTION: A power board 1 is equipped with a plurality of fixed insulating cylinders 2 and board side terminals 3a and 3b projected to the insides of the insulating cylinders 2, and the board side terminals 3a and 3b are provided up and down at an interval each three phase.
