Title: Manufacture of semiconductor device
Inventor: KOGA TERUHIDE
IPC: H01L21/768
Filed: 1988-01-28
Abstract: PURPOSE:To enable a taper angle required for a fine contact hole to be made by a method wherein the surface of an insulating film wherein a contact hole is to be made is made rugged by sputter-etching process and then the insulating film is isotropically wetetched to be further anisotropically etched using a resist as a mask. CONSTITUTION:The first Al3 is selectively etched away by RIE process to remove resist, an insulating film 4 is deposited to be flattened for patterning contact and then another resist 5 is selectively left. First, the residual resist scum 7 on the bottom of contact can be removed by sputter-etching process using e.g., Freon based gas. Besides, the exposed insulating film 4 takes rugged surface shape 6. Second, the insulating film 4 is isotropically etched away to take taper-angled shape by etching process with wet etchant using the resist 5 as a mask. Lastly, a taper-angled contact hole can be formed by anisotropically etching away the insulating film 4 with e.g., reactive ion etching process using the resist 5 as a mask.

Title: Manufacture of heat absorption surface for solar heat collector
Inventor: KOITABASHI MASAYASU
IPC: F24J2/48
Filed: 1981-02-05
Abstract: PURPOSE:To contrive to simplify the manufacture and to reduce the production cost by a method wherein a thin layer of substance, which chemically changes by heating into a constituent member having a large rate of absorption of solar heat, is provided on a substrate with a small rate of thermal radiation and, after that, heated. CONSTITUTION:Firstly, for example, a stainless steel substrate is degreased and cleansed. Secondary, the surface of the substrate is sprayed with suspension of iron hydroxide slowly enough not to cause dripping off. The suspension is the aqueous mixed solution of ferrous hydroxide[Fe(OH)2O]and ferric hydroxide [Fe(OH)O], the ratio of content contents of which is prepared to be 1:2 by molar fraction, dispersed in water. The thickness of the thin film obtained by spraying is rendered to be not more than about 10mum. After being thoroughly dried, the thin layer is heated in air, for example, at 400 deg.C for 30min so as to chemically change the iron hydroxide thin layer into the triferric tetroxide (Fe3O4) layer, resulting in turning to be the absorption surface having a large rate of absorption of sunbeams.

Title: Sweating cooler
Inventor: MORIBE NOBUYUKI
IPC: F28F3/06
Filed: 1992-01-31
Abstract: PURPOSE:To efficiently reduce the contact thermal resistance of a sweating cooler to improve its efficiency by attaching a porous plate to a by diffusion welding. CONSTITUTION:A 12 is bonded with the upper face of a cooler main body 10 via a separation plate 11. A porous plate 21 formed of sintered aluminium powders is joined with the inside of the yellow part of the 12 by diffusion weldering in a manner that the lower half part of the space in the yellow part 19 can be filled. As a result, the heat of a cooled liquid is conducted from the separation plate 11 through the 12 to the porous plate 21 and the coolant supplied to the lower face side of the porous plate 21 evaporates due to the heat conducted from the cooled liquid. Since the porous plate 21 is metallically bonded with the 12 by diffusion welding, the contact thermal resistance is reduced to the same level as the thermal conductivity rate of metal.

Title: Optical pickup device and optical recording medium discriminating device
Inventor: AKIBA TAICHI
IPC: G11B7/135
Filed: 1995-02-02
Abstract: PURPOSE: To allow a single pickup device to reproduce plural kinds of discs whose protection layer thickness differs from each other and to easily discriminate the plural kinds of discs whose protection layer thickness differs from each other. CONSTITUTION: A spherical aberration correction means 6 of the pickup device 1 is inserted into/withdrawn from an optical path between a light source 2 and an objective lens 9 based on an external optical recording medium discrimination signal SD. The single pickup device conducts optimum reproduction by correcting spherical aberration different from each other for every optical recording medium. Furthermore, since an optical recording medium discrimination device 12 discriminates each optical recording medium based on a voltage corresponding to a current flowing to a focus coil nearly at a focal point, each of the plural kinds of optical recording media in which a distance from the surface of each optical recording medium to an information recording face differs from each other is easily discriminated.

Title: Chemical injecting device
Inventor: SHIBAZAKI MITSUHIRO
IPC: E02D3/12
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To prevent a packer from damage due to rubbing against the inner wall face of a boring hole by providing a packer element with a cylindrical slide part having an end part whose inner periphery is formed in a hexagonal form, and providing a shaft to mutually slidably engage on the end of the slide part. SOLUTION: In the case of the excavation of a boring hole, a shaft part 4a rotates a monitor part 8 to excavate with a bit 8a. When a specified depth has been excavated, compressed air is supplied through an air chamber 6 into a packer 2 to expand it. In this case, a slide part 9 slides inside the monitor part 8, and slides against a spring 10 toward the packer. In this place, when chemical is injected through the shaft 4a, and air pressure is removed, since the sealed part 2a of the packer 2 is made to easily contract by the spring 10, the next excavation can be easily proceeded. Thus in the case of the contraction of the packer, it is certainly contracted in the direction of deformation to prevent the packer from damage due to rubbing against the inner wall face of the boring hole.

CONSTITUTION:An elastic cleaning blade 11 consists of a rubber or plastics having a proper elasticity and has the front end cut partially and has an L shape where a thickness t2 in a front end part 112 is thinner than a thickness t1 to a holding part 111, and the thickness t1 is so set that increase of the pressure, especially, near the holding part 111 having the thickness t1 (a free length l2) is reduced sufficiently when a free length L from a side end (h) of a holder part 101 to a front end (i) is shortened in comparison with a conventional blade. Thus, since the free length l2 of the thin front end part 112 is shortened, rigidity of the balde 11 is not extremely weakened through the thickness t2 is made thin, and the front end part 112 of the balde 11 is kept pressed to a photosensitive body 1a with a desired contacting force.

Title: Vacuum type hot-water machine
Inventor: HAYASHI HIROSHI
IPC: F24H1/52
Filed: 1995-02-06
Abstract: PURPOSE: To prevent a heat transfer rate from lowering owing to non- condensable gas, by a method wherein water flowing through the heat-exchanger is heated by the high-temperature liquid. CONSTITUTION: A heat-exchanger 4 for receiving heat is immersed in water or liquid 2 as a heating medium which is in a boiler 1, and the water 2 in the boiler 1 is heated by operating a burner 5. The water 2 heated is circulated by convection, and the heat of the water 2 is transmitted to the heat-exchanger 4. Water flowing through the heat-exchanger 4 is heated by the heat of the hot water 2 and is sent out for hot-water supply or for heating rooms. Non- condensable gas is extracted by an automatic bleeder 7 when generated in the boiler 1 or led thereinto. In this way, the non-condensable gas does not exert a bad influence on heat transmission to the heat-exchanger 4 even if the non-condensable gas is generated in the boiler 1 or is led thereinto, and hence the water flowing through the heat-exchanger 4 can be efficiently heated.
