Patent JP-S58170900-A (JP)
Title: Pump
Inventor: TSUKUI KEITAROU
IPC: F04F1/04
Filed: 1982-03-31
Abstract: PURPOSE:To enable to convey hot water or the like under pressure by the use of only the heat energy possessed by the hot water, by expanding an expansible container by the pressure of hydrogen gas released by heating a hydrogenated metal of a hydrogen occluding alloy having adsorbed hydrogen gas, and conveying a fluid under pressure by the pressure produced through expansion of the container. CONSTITUTION:When the pump is inserted into a container 2 filled hot water 1 and fixed correctly in place by use of legs 12 with a valve 9 being closed, the temperature of a hydrogen occluding alloy 6 having adsorbed a large amount of hydrogen gas is raised and the alloy 6 releases high-pressure hydrogen gas. Resultantly, the pressure of hydrogen gas is transmitted to the inside of a frame 8. When the pressure exceeds a prescribed value, the valve 9 is opened and the high-pressure hydrogen gas is introduced into an expansible container 10 through an opening 11, so that the container 10 is expanded. Here, since the frame 8 is held in tight contact with the inner peripheral surface of the container 2, hot water 1 in the container 2 pressurized through expansion of the expansible container 10 is discharged to the outside of the container 2 via a discharge pipe 13 without causing leakage of hot water 1 through between the outer surface of the frame 8 and the inner surface of the container 2. Thus, it is enabled to draw up a fluid by use of only the heat energy possessed by the fluid to be conveyed.

Abstract: PURPOSE:To enhance the electromigration resistance of Al wiring in a semicon ductor device. CONSTITUTION:After the formation of an interlayer insulating film 2 directly on a silicon substrate 1 or through the intermediary of an insulating film, a conductive film is deposited on the interlayer insulating film 2 to be etched away for the formation of a wiring 3.

IPC: H01L21/205
Filed: 1980-04-23
Abstract: PURPOSE:To readily form a chip of a light emitting element, to readily form an N type side electrode and to readily identify the electrode by forming a sapphire substrate, a Ga epitaxial layer and an N type conductive isolation region. CONSTITUTION:An N type GaN layer 23 and an I type GaN layer 33 are grown by a vapor growth on a sapphire substrate 13 on which an alumina film 63 of predetermined pattern is formed. At this time a conductive crystal 73 exhibiting N type having disordered crystal array is grown on a part of the film 63. Since the GaN wafer thus grown has an independent single crystal region, a stress is dispersed to cause the bent as a whole to become small and concurrently cracks in the substrate 13 and in the GaN crystal are largely reduced. Since the width of the band can be increased larger than the cutting margin determined by the thickness of a cutting machine at the time of cutting and the cracks can be reduced, the chip may not patly cut out and its yield can be remarkably improved.
