Title: Method of and apparatus for treating surface of substrate
Inventor: NODA SEIJI
IPC: H01L21/027
Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To increase a treating speed by using high concentration ozone efficiently by making a structure at least from an ozone supply port to an object to be treated sealable so that no gas/liquid interface exists between the ozone solution supply port and the object. SOLUTION: A high concentration ozone aqueous solution produced by an ozone aqueous solution generator 4 is supplied from an ozone solution supply port 5 to a reaction treatment tray 1 of about 1 m2 cross-sectional area and 0.05 m depth, and a silicon substrate 3 coated with a photoresist film 2 is placed in the liquid of the tray 1. A plate-shaped lid 7 is fitted to the tray 1, and the solution in the tray 1 is sealed. The supplied ozone solution is discharged from an ozone discharge opening 8. In this way, in a process in which the high concentration ozone solution is brought into contact with an object to be treated, since no gas/liquid interface exists between the supply port 5 and the object, the release of the dissolved ozone into a gas phase can be prevented, and the dissolved ozone can efficiently be used.

Title: Wind direction control method for air conditioner
Inventor: NAKAMURA KEIICHI
IPC: F24F11/02
Filed: 1988-08-23
Abstract: PURPOSE:To raise the sensory temperature in order to attain a comfortable atmosphere in a whole room quickly by performing downward air heating operation, in which warm air blows toward the feet, immediately after start-up of heating operation, then performing double air flow heating after the room temperature reaches a specified temperature, and dividing the double air flow into the outward directions when a specified period of time has elapsed after start-up of heating operation. CONSTITUTION:In heating mode operation, left and right wind guide vanes 12 are turned in the direction parallel to the wind flow generated by an indoor fan unit 6, and a main wind guide vane 10a and a sub wind guide vane 10b of up and down wind guide vanes 10 are turned in nearly vertical direction. Thereby, down air heating takes place, and warm air blows out from an air outlet toward the feet. The down air heating continues until the room temperature reaches a specified temperature. After that, the sub wind guide vane 10b of the up and down wind guide vanes 10 is turned in nearly the horizontal direction. Then, double air flow heating takes place, and not only the floor but also the wall are heated. When the double air flow heating continues for a specified period of time after start-up of heating operation, the right and left wind guide vane groups 12b and 12a are turned in the outward directions opposite each other to carry out surrounding heating.

Abstract: PURPOSE:To provide an antiskid control device which is adapted to control a brake fluid pressure only by a switching valve without requiring any liquid pressure pump, and which can accomplish suitable braking control in a small-sized and light-weighted construction and can keep good brake operation feeling. CONSTITUTION:According to the judging result of a road surface condition judging means, the closing interval of a normally open switching valve 31 is set, and the slip condition of a wheel is judged at least according to an output signal of a wheel speed detecting means 41.

Inventor: TANAKA KISABUROU
IPC: B23K25/00
Filed: 1983-11-10
Abstract: PURPOSE:To maintain the upper part in the welding space owing to shrinkage on welding at an adequate gap and to permit prevention of the deformation in the adjacent spaces and to facilitate the detaching of a water cooled copper plate by tapering the welding space between a pair of billets facing each other to widen the side where welding ends and inserting a restraining plate in the adjacent space which is not welded. CONSTITUTION:The gap in a welding space 4 is preliminarily made as wide as to allow for shrinkage on welding and a restraining plate 13 formed to a desired size is inserted into the adjacent welding space 4 which is not welded and therefore even if the inside of the space 4 shrinks, stable welding is accomplished. The deformation due to shrinkage of the adjacent space which is not welded is prevented and a water cooled copper plate 6 is easily removed upon ending of welding. The plate 13 is more effective as said plate is provided nearer the rear of the plate 6 and after welding said plate is cut and removed by gaseous oxygen, acetylene, etc.

Title: Air pressure-applied excavating/sucking device
Inventor: HASHIMOTO KIKUO
IPC: E02F3/88
Filed: 1991-07-26
Abstract: PURPOSE:To improve the dredging capability, suppress the diffusion of mud into water, and reduce the mixed water. CONSTITUTION:The first nozzle 13 and the second nozzle 16 are provided on a pipe-like header 11 connected to the tip of a dredging discharge/feed pipe 20. The first nozzle 13 ejects air to the front of the header 11 to excavate the sea bottom or the liver bottom. The second nozzle 16 ejects air to the depth in the header 11. The air ejects from the second nozzle 16 generates strong suction force in the header 11. The gravelly sand and mud accumulated on the sea bottom or the liver bottom are efficiently sucked into the header 11 in conjunction with the excavation by air. The water quantity in the mixed water is reduced because a large quantity of air is contained in it.

IPC: G01J1/02
Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To obtain a photodetector with a light interceptor having a simple structure, by sandwiching a resilient body between the base part and a shutter plate fixed to the other end of a flexible electrode plate having one end secured to the base part. SOLUTION: A photosensitive element 2 for detecting incident infrared rays and transducing it into an electric signal is secured to the bottom part at the basic part 1 and an opening 4 is made in the cover part 3 directly above the photosensitive element 2. A flexible electrode 6 is secured to the bottom part at the basic part 1 such that the electrode 6 touches the lower end of an electrode plate 5 secured to the inner side face at the basic part 1 and a shutter plate 7 fixed to the other end thereof slides to the left and right while being supported by a guide rail 8. When the voltage is not applied to both electrode plates, the shutter plate 7 is urged to the left by a spring 9 interposed between the shutter plate 7 and the basic part 1 to block the opening 4 thus intercepting the incident light.  When a DC voltage is applied, the flexible electrode 6 is attracted electrostatically to the fixed electrode plate 5 and the shutter plate 7 is shifted to the right while resisting against the spring 9 thus releasing the opening 4. More specifically, a light interceptor can be constituted easily by applying a DC voltage at a specified period thereby intercepting the incident light periodically.
