Title: Manufacture of semiconductor device
Inventor: SAKAI HIROYUKI
IPC: H01L21/3065
Filed: 1981-12-22
Abstract: PURPOSE:To minimize the bird beak produced in case of selective oxidation perfectly preventing bird head production by a method wherein silicon nitride is left steadily on the side of opened silicon substrate. CONSTITUTION:As shown in the figure, the oxide film 14 is formed on the opened part of a n type semiconductor substrate by thermal oxidation. After entirely being formed by CVD processing, if the silicon nitride film 15 is entirely etched by dry etching with remarkable anisotropy, the opened bottom of n type semiconductor substrate and the silicon nitride film only formed on the silicon nitride 13 are exclusivey etched while the silicon nitride film 15 only formed on the side of opened part is left self-matchable. The effect of leaving silicon nitride film 15 on the side of opened n type semiconductor substrate 11 only is to prevent water or oxgen from being supplied in the lateral direction not to produce bird beak at all. The oxide film 17 is formed by selective oxidation in the figure preventing bird beak and bird head from being produced at all.

Abstract: PURPOSE:To eliminate head and thereby obtain flat surface by coating the entire surface including birds' head generated at an oxide film surface with the resist film, on the occasion of isolating element regions formed on the semiconductor substrate into islands by a selective oxide film, and executing the ion etching by utilizing that the resist film is this on the heads. CONSTITUTION:An N<+> type layer 2 is formed by the epitaxial growth method on a P type Si substrate 1, a field SiO2 film 6 which enters the substrate 1 is formed by the selective oxidation and the layer 2 is isolated like an island. Next, a P type base region 3 is formed by diffusion in the layer 2 formed like island and an N<+> type emitter region 4 is then formed in such region, thereby forming a semiconductor device. In this case, according to the selective oxidation, namely LOCOS method, the birds' beak 7 and birds' head 8 are generated at the surface of film 6 and thereby the surface becomes uneven. Therefore, the ion etching of Ar, etc. is carried out to the entire part utilizing that the entire part is coated with the resist film 9 and the film 9 is thin on the head 8 in order to eliminate the head 8 and make flat the surface.

IPC: H01M10/613
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To provide a battery case having sufficient strength and preventing cooling effect from decreasing, even if manufacturing or assembling errors occur. SOLUTION: A plurality of ribs 22, 24, having circular cross sections, are alternately formed on laminated surfaces of a battery case 20. When the battery case 20 is laminated, the ribs 22, 24 abut on parts of the adjacent battery case 20 where the ribs 22, 24 are not formed for forming a passage 26 for cooing media (for example cooling wind). Even if a manufacturing or assemble error occurs, since stress acting on the ribs 22, 24 is the same as that when error does not occur, it is not necessary to design, making allowance for errors, and cooling performance is prevented from decreasing.

Title: City refuse incinerator
Inventor: UEDA SEIICHIRO
IPC: F23G5/00
Filed: 1987-08-20
Abstract: PURPOSE:To enable free variation of a balance between amounts of air under a stoker and air on an air-cooled wall, by a method wherein a return duct, through which a part of cooling air is sucked out, is situated to the air-cooled wall of an incinerator, the return duct is connected to the air feed line of the stoker, and a part of cooling air in the air-cooled wall is fed in the incinerator. CONSTITUTION:When the temperature of the incinerator wall of an air-cooled wall 8 is high and there is a need to feed a large amount of cooling air to a cooling chamber 9 of the air-cooled wall 8, a damper 13 of an air-cooled wall blower 11 is opened to feed a large amount of cooling air to a cooling chamber 9. Meanwhile, a damper 15 of a return duct 14 is widely opened, cooling air in the cooling chamber 9 is sucked out in the return duct 14, and the amount of air flowing into an incinerator from the front of the cooling wall 8 is suppressed. A damper 7 is regulated so that a forced blower 5 compensates for an air amount by which an amount of air fed to a position below a stoker 2 through the return duct 14 is insufficient. As noted above, by means of the opening angles of the three dampers 7, 13, and 15, a balance between an amount of air charged into the incinerator from the air-cooled wall 8 and an amount of air charged into the incinerator from a position below the stoker can be regulated.

Inventor: AOKI RYOICHI
IPC: B01J20/02
Filed: 1984-10-08
Abstract: PURPOSE:To cake waste in a short time by adding a material, obtained by adding calcium sulfate, etc. to the material which is obtained by calcining and activating alunite in presence of cement, to the remaining flocculated material obtained by removing water to the utmost from said waste contg. an org. material or an org. material and a large amt. of water. CONSTITUTION:A material obtained by adding, if necessary, calcium sulfate, alumina, etc. to the calcined and activated alunite or the material added with low sulfuric acid-type ettringite double salt contg. 14-16 molecules of water of crystallization, calcium sulfate, alumina, etc. is added to the remaining flocculated material obtained by adding a flocculant to waste contg. an org. material or an org. material and a large amt. of water to remove water to the utmost. Consequently, ettringite is effective ly formed and grown in the presence of cement, and a porous mixture or the mixture having many capillaries is prepared. Or a highly water-absorptive substance such as bentonite, if necessary, is added to the waste in the absence of cement, and the whole material is caked by a layered acid clay derivative and its caking catalyst. Consequently, said waste can be caked in a short time (46-96hr on average) without heating and under natural conditions.

Title: Photographing lens for underwater camera
Inventor: KIMURA KAZUO
IPC: G03B17/08
Filed: 1986-09-06
Abstract: PURPOSE:To automatically attain proximity setting with a simple structure at the time of underwater photographing by arranging a transparent flexible member in front of a lens so that the member is deflected by water pressure at the time of underwater photographing. CONSTITUTION:The transparent flexible member 2 is arranged in front of the photographing lens 1, the front face 2a side of the member 2a is exposed and the rear face 2b side is water-proofed so that the member 2 is deflected like a recessed surface by water pressure at the time of underwater photographing. Since water pressure is applied to the front face 2a of the member 2 and the rear face 2b is water-proofed at the time of underwater photographing, the front face 2a is deflected to the object side so as to be recessed by the pressure difference. Thereby, proximity setting can be automatically attained under water. Since the water pressure is increased in accordance with deeper dive, the deflection of the member 2 is also increased and the radius of curvature of the recessed surface is reduced, so that the degree of proximity setting is increased at a deep position to which light can not be easily projected.

IPC: F23R3/34
Filed: 1987-08-26
Abstract: PURPOSE:To stably burn a premixed flame on the side of a dilute mixed gas under a high-speed condition by providing a barrier member with respect to a premixed gas flow in the vicinity of an outlet part of an annular premixed flow passage thereby to form a stable flame in a recirculation flow region at the downstream of the barrier member. CONSTITUTION:An annular flow passage formed by an inner peripheral flow passage wall 6 and an outer peripheral flow passage wall 6 of the burner is partitioned peripherally by a flame holding plate 7. A second stage fuel is supplied to respective partitioned flow passages, and a premixed gas is supplied to a main chamber combustion cylinder 1. Further, a flame holding plate 7 at the outlet part of the annular flow passage is tapered toward the side of the inner peripheral flow passage wall, and a barrier member 8 is provided at the downstream inner peripheral flow-passage wall of the flame holding plate 7. This barrier member 8 is provided over the entire periphery of the inner peripheral flow passage wall. Thereby, immediately after passing of a part of the premixed gas flow along the inner peripheral flow passage wall 5 through the barrier member 8, the flow passage rapidly expands to create an exfoliation and to form a recirculation flow. In this recirculation flow, a stable small flame is formed since the staying time of the premixed gas is long, thus the stability of the main flow flame being improved.
