Patent JP-H0376276-A (JP)
Title: Switching element
Inventor: KAYANE NAOYUKI
IPC: H01L33/62
Filed: 1989-08-18
Abstract: PURPOSE:To judge whether a switching element is in an ON or an OFF state from ON-OFF state of a light emitting element by a method wherein the light emitting element, which emits light by a control current, is connected to a control terminal through which the switching control current is made to flow. CONSTITUTION:When the output control signal of a control circuit 4 is at a zero level, no base current flows through a transistor 1, so that the transistor 1 is put in an OFF state, in result as no current flows through a light emitting diode 2, consequently the light emitting diode 2 emits no light. When the output control signal of the control circuit 4 is at a high level, a base current flows through the transistor 1 through the intermediary of the light emitting diode 2, and the transistor 1 is turned 'ON'. At this point, as a base current flows through the light emitting diode 2, the diode 2 emits light. As mentioned above, the light emitting diode 2 emits light when the transistor 1 is ON and no light when the transistor 1 is OFF, so that it can be recognized by viewing the emission of the light emitting diode 2 whether the transistor 1 is in an ON or an OFF state.

Title: Semiconductor device
Inventor: SATSUMA KAZUMASA
IPC: H01L21/322
Filed: 1988-08-26
Abstract: PURPOSE:To suppress an operation of a parasitic transistor without deteriorating a characteristic of a device by a method wherein the recombination center is formed locally only inside a P-type substrate. CONSTITUTION:A semiconductor device is composed of the following: a semiconductor substrate 1 of a first conductivity type; a layer of a second conductivity type formed on the substrate 1. The layer of the second conductivity type is separated into two or more island regions 3a, 3b of the second conductivity type by an impurity region of the first conductivity type or a separation region 4 composed of a dielectric. The recombination center X of a small number of carriers is formed at a density which is higher than that inside the regions 3a, 3b at least in one part of the substrate 1 surrounding the regions 3a, 3b. The center X disappears by quickly recombining electrons as the small number of carriers which have been injected into the substrate 1. Thereby, an operation of a parasitic transistor can be suppressed.

Title: Method for carburizing sintered material
Inventor: ODOHIRA TOSHIHIKO
IPC: C23C8/22
Filed: 1983-11-15
Abstract: PURPOSE:To carry out hot hydrostatic pressing treatment and carburization at the same time and to obtain a dense sintered article by using a carburizing gas as a gaseous pressing medium in the hot hydrostatic pressing treatment and by suddenly releasing the gas after the treatment to carry out hardening by cooling. CONSTITUTION:When a sintered alloy is subjected to hot hydrostatic pressing treatment, a carburizing gas is used as a gaseous pressing medium.

Title: Surface treatment method for spring
Inventor: ISHIDA MASAAKI
IPC: C21D7/04
Filed: 1998-07-29
Abstract: PROBLEM TO BE SOLVED: To improve durability and fatigue failure resistance of a valve spring and a clutch spring by nitriding a surface layer of the springs, and projecting a large number of hard metallic particles having a diameters in a specific range at a collision speed not less than a specific value on the surface of the nitrided springs. SOLUTION: An alloy steel oil tempered wire for a spring is molded as a spring, annealed for residual stress removing, then the seat surface is polished and a surface scale is removed nitriding. As shot peening after nitriding, a hard metallic particle or a cemented carbide particle having a dimension of a diameter of 20 to 80 m is projected at a speed not less than 80 m/sec. The spring having excellent durability in fatigue resistance and settling resistance can be obtained by securing transposition/fixation in an influencing layer of a shot by low temperature annealing. Thus, even when repetitive stress amplitude is comparatively large, fatigue breaking from the surface can be prevented, and the fatigue service life in high stress can be largely improved.
