Title: Method of cleaning ventilation duct
Inventor: PAA INGE UOREN
IPC: B08B9/02
Filed: 1990-11-16
Abstract: PURPOSE: To perform a cleaning operation for a ventilation duct effectively as well as at a low cost by allowing a strong air flow to pass through the ventilation duct so that at least one cleaning member having the same cross sectional shape as that of the duct passes through the ventilation duct with the aid of the air flow. CONSTITUTION: When a cleaning operation is performed for a ventilation duct (3) which is one of ventilation ducts, a suction car, a large-sized ventilation device, a large-sized suction device or a duct trap, for example, is mounted to it through an attachment (16). All openings (7, 8, 9) are closed, a brush formed so as to correspond or conform to the cross-sectional shape of the ventilation duct (3) is put into the duct from the opening (17), for example, and an air flow is allowed to pass through the ventilation duct (3) at a high speed. The speed of the air flow is selected in relation to a structure of the duct. In addition, a pressurized air is blown into the ventilation duct (3) in order to remove dusts which are broken up into pieces.

Filed: 1991-11-27
Abstract: PURPOSE:To provide a semiconductor device where integration is enhanced by opening a bottom surface part of a polysilicon film covering a hole, in self- alignment manner for the hole. CONSTITUTION:In the structure where a polysilicon film 4 covers a hole which is formed on a surface of a semiconductor substrate 1, a thin silicon oxide film 11 is formed on a surface of the polysilicon film 4, a thick silicon nitriding film 12 according to the plasma CVD method is formed, and then etchback is performed, thus enabling the silicon nitriding film 12 to remain only within the hole. After that, oxidation is performed for forming a silicon oxide film 13 on the polysilicon film 4 outside the hole and then the silicon nitriding film 12 is eliminated, thus enabling the polysilicon film 4 at the bottom surface part to be opened to the side surface in self-alignment manner. This configuration allows an occupation area of the hole itself to be greatly reduced as compared with that of the conventional method since the bottom surface of the hole can be opened at all regions.

IPC: B21D5/14
Filed: 1998-11-04
Abstract: PROBLEM TO BE SOLVED: To improve the shape of a tube forming so that the bending area of a roll becomes a specific length, using a material whose both edges of a tip and a rear end have been bent in advance over a specific length, and making small an opening generating in a center part in the longitudinal direction of the tube. SOLUTION: By using a material whose both edges of a tip and a rear end have been bent by 1/5 or over of the peripheral length of a tube, the tube is formed so that the bending area of a roll becomes <3/5 of the peripheral length of the tube. Preferably the bending area of the roll becomes <3/5 of the peripheral length of the tube by stopping the rolls at the tip and the rear end part of the material so that the tip and the rear end part with their edges bent are not deformed by the rolls. Also, by widening the gaps of plural rolls, it is sent so that the bending area of the roll becomes <3/5 of the peripheral length of the tube. An edge bending area is enlarged to >1/5 of the peripheral length of the tube by pressing or roll bending. Consequently, even to the tube with a small diameter, to which an upper roll with a large diameter can not be used, an opening can be controlled, and the tube with high strength and a thick wall and of a long size material can be manufactured.
