Filed: 1987-05-12
Abstract: PURPOSE:To eliminate galling of foreign matters between the top surface of an end late and a bottom plate, by arranging a shock absorber interposed between an instrumentation guide body arranged within a lower plenum and a lower end plate to be made up of an outer cylinder erected on the bottom plate placed on the top surface of the end plate and a guide cylinder inserted relatively movably thereinto. CONSTITUTION:A shock absorber 20 is interposed between an instrumentation guide body arranged within a lower plenum and a lower end plate 11a of a pressure water type nuclear reactor. The shock absorber 20 has a bottom plate 21 placed on the end plate 11a, an outer cylinder 22 erected on the bottom plate 21, an intermediate cylinder 24 welded securely 7 on the top of the outer cylinder 22 and a guide cylinder 23 relatively mobile with respect to the intermediate cylinder 24.

Abstract: PURPOSE:To prevent latchup by providing a semiconductor device between a P-channel in a CMOS inverter constituting an output circuit and an output so as to bring the level of the drain into a power supply voltage or below. CONSTITUTION:A MOS transistor (MNOS TR) Q6 is turned on normally and acts as a CMOS inverter.

Title: High-voltage transformer
Inventor: HIYOUGO TAKASHI
IPC: H01F38/12
Filed: 1992-05-07
Abstract: PURPOSE:To miniaturize a transformer without influencing the step-up ratio by setting the thicknesses of the insulating pipe of a bobbin by steps in response to the potential values shared by each coil of a high-voltage coil and setting the coiling number of each coil in reverse proportion to the thickness of the insulating pipe. CONSTITUTION:A bobbin 12 provided on a high-voltage transformer 11 is permitted to set the depths of grooves 61-65 formed in lines on a pipe 12A by steps and the pipe thicknesses which fix the insulating distances between the coils 51-55 and a leg 1a are permitted to be thicker for the coil which has higher potential. The coiling number is set larger for the coil which has lower potential according to the coil storing capacity due to the depths of the grooves 61-65. Thus, the step-up ratio is increased without increasing the sizes of the transformer and the transformer is miniaturized for the same step-up ratio.

Abstract: PURPOSE:To increase bonding strength, by forming a bonding wire with an Al alloy, including 0.002-0.5% of Ti, less than 0.05% of Fe and less than 0.03% of Si. CONSTITUTION:An alloy, which includes 0.002-0.5% of Ti, less than 0.05% of Fe and less than 0.03% of Si, and comprises Al for the rest of the above described elements, is used for manufacturing a bonding wire. The Ti prevents the enlargement of crystal grains of the wire into rough grains at and in the vicinity of a ball when the ball is formed at the time of bonding. Thus the strength and reliability of the bonding are improved. By specifying the rate of inclusion of the Fe in the alloy to be less than 0.05% and that of the Si to be less than 0.03%, wire drawing property is enhanced. In order to prevent the oxidation when the Al is fused and to improve ball forming ability, Be can be added in the range of 0.0005-0.1%. In order to improve corrosion resistance, 0.1-2.0% of Mn can be included.
