Title: Frequency adjusting method for surface acoustic wave device
Inventor: KADOTA MICHIO
IPC: H03H3/10
Filed: 1986-04-01
Abstract: PURPOSE:To simply form a thin film, to decrease the propagation loss and conversion loss attended with the forming of thin film and to withstand an organic solvent by using a polyester imide group resin as the thin film and changing the film thickness thus formed. CONSTITUTION:A mask 2 made of a material such as stainless steel is arranged on a surface acoustic wave base 1 on which electrodes are formed already and the thin film forming is limited to a part where a window 3 of the mask 2 is formed. The shape and size of the window 3 are considered not to form the thin film to a terminal electrode included in the surface acoustic wave device. The polyester imide group resin constituting the thin film has a comparatively larger Young's modulus but with a low density and applied onto the base 1 by using a simple spray such as a spray gun 4. In using the spray, the polyester imide group resin is diluted by a specific solvent and the diluted resin is supplied to the spray gun 4. The thickness of the thin film of the polyester imide group resin is easily adjusted by the spray time and the viscosity.

Title: Wide-angle nozzle for head lamp cleaner
Inventor: OKUMA SHIGEKI
IPC: B60S1/52
Filed: 1987-03-31
Abstract: PURPOSE:To efficiently diffuse and spray ejected washing water while forming water droplets, by providing a turblent flow forming bead projection to the inner end of a washing water jet orifice on the drain edge side thereof so as to be formed in a protruding state on the side of the vortex stream forming cavity part of said inner end. CONSTITUTION:The washing water supplied to a vortex stream forming cavity part 8 under appropriate pressure forms the high speed water stream from a washing water jet orifice 7. At this time, since a bead projection 11 is provided to the inner end of the jet orifice 7, the upper part washing water flows while divided to form a high speed vortex stream in the vicinity of the jet orifice 7. Since this vortex stream is formed as a turblent stream wherein the center of the vortex stream always vibrates by the water stream deflecting action of the bead projection 11, said vortex stream is rapidly reduced in pressure when discharged from the jet orifice 7 to be formed into water droplets. Then, the washing water is ejected at a predetermined diffusion angle in the jet direction regulated by a water jet direction of regulating edge 9 whose front edge protrudes in a bill shape and a drain edge 10 and impinges against the front surface of a head lamp at a high speed to wash the same.

Abstract: PURPOSE:To enable a held weatherproof curtain to sufficiently withstand horizontal wind load by providing a horizontal beam elevatingly at plural columns erected along a quay, and forming the horizontal beam as a truss frame of U-shape in a plan view. CONSTITUTION:When there is no wind or the like, a wire rope 30 is wound to make a horizontal beam 6 ascend to fold hanging support bodies 7, and a weatherproof curtain 12 is also folded and enclosed on the roof 5 side to perform cargo loading/unloading an a ship S brought alongside a quay. When there is a little wind, a winch is driven from the moved-up state of the horizontal beam 6. A guide roller R thereby rolls on elevating rails 2a, 3a, and the horizontal beam 6 descends. In association with this, links 8, 9 forming the hanging support bodies 7 are extended downward from the folded state, and the weatherproof curtain 12 is extended downward. At this time, even if normal wind load acts upon the weatherproof curtain 12, the horizontal beam 6 withstands this firmly because of its truss frame of U-shape in a plan view, and the hanging support bodies 7 are reinforced because of being supported at both ends.

Title: Substrate-treating device
Inventor: ARIOKA MASAHIRO
IPC: H01L21/677
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To provide a substrate treating device by which delays in transfer are prevented, without restricting entry of substrates and decrease in the throughput can be prevented. SOLUTION: A substrate-treating pattern by which substrates pass through a chemical liquid bath CB1, a rinsing bath WB1, a rinsing bath FR and a drying part SD is set. The substrates are transferred by a substrate-transferring robot TR according to the treating pattern. When the treatment time in the water washing bath FR is long, transfer is delayed because the substrates after treatment in the rinsing bath WB1 cannot be transferred into the rinsing bath FR. In this case, treating pattern is changed in such a way that substrates after treatment in the water washing bath WB1 have been transferred into a water rinsing WB2, then into the rinsing bath FR. In this way, since the rinsing bath WB2 performs a function of a buffer, the delay in transfer can be prevented without restricting entry of substrates, and decrease in the throughput can be also prevented.
