Title: Semiconductor device
Inventor: HOSOE HIDEYUKI
IPC: H01L21/60
Filed: 1983-10-17
Abstract: PURPOSE:To improve the lifetime of solder bump parts by a method wherein liquid conductive members are arranged on a semiconductor substrate, bump electrodes being joined on these members, and at least a semiconductor chip and the junctions of said members with the bump electrodes being then covered with an insulation film. CONSTITUTION:The liquid conductive members 2 are placed on the mounting substrate 1. The substrate is made of a ceramic substrate or the like, and e.g. Hg is used for the conductive member. After the semiconductor chip 4 having the bump electrodes 3 on the back is joined on these members by positioning of the solder bumps to the members, the junctions and the chip are covered with the insulation film 12. The chip mounted by junction on the members is fixed by this insulation film, and the efflux of the members is thus prevented. The solder bumps are not directly fixed to the substrate, and can move in this film because the member is liquid-form. Therefore, unnecessary stress is not applied on the solder bumps, and cracks and the like are not generated.

Title: Oil flow indicator
Inventor: SAITO SHIGEMI
IPC: H01F27/12
Filed: 1985-09-03
Abstract: PURPOSE:To improve operational reliability, by forming an enclosure around a blade turning by oil flow in an oil flow indicator and providing an oil pump inlet side of the enclosure with a turning plate. CONSTITUTION:In the presence of an oil flow, a blade 8 and a turning plate 11 are pushed to turn, with a needle 15 indicating a flow. When the oil flow stops, action of a tension spring 20 makes the needle 15 indicate 'stop' and actuates a micro-switch 18 for telling alarm. When a turbulent flow occurs inside an oil pipe 7, an enclosure 10 around the blade 8 serves as a straightening plate to prevent the needle 15 from vibrating. When an oil pump 3 is driven with valves 5 closed, a complicated turbulent flow occurs inside the oil pipe 7; however, the blade 8 is prevented from turning under the influence of the turbulent flow, with the needle 15 normally indicating 'stop' because an oil pump 3 side of the enclosure 10 is closed by the straightening effect of the enclosure 10 and by action of a spring 12 on the turning plate 11. Thus, vibration of the needle can be avoided at the time of a turbulent flow and detection of abnormality in a cooler system can be performed securely.
