Title: Hot-melt adhesive containingtive adhesive poly(vinyl alkyl ether),for polyethylene and polypropylene
Inventor: MACHIYUU ARUBAATO KARUZUITSUKU
IPC: C09J123/06
Filed: 1989-12-25
Abstract: Hot-melt adhesives based upon a mixture composed of poly(vinylmethylether), greater than 50 weight percent of a thermoplastic resin, and optionally a tackifier resin, are found to be superior for the binding of polyolefins such as polyethylene, polypropylene, or ethylene-propylene copolymers to themselves and to other substrates. In particular, the hot-melt adhesives are useful for bonding polyethylene-backed and latex-backed carpet to polyethylene, polypropylene, or ethylene-propylene copolymer.

Title: Printed circuit board
Inventor: KUWABARA SHIGEO
IPC: H05K3/28
Filed: 1996-12-03
Abstract: PROBLEM TO BE SOLVED: To visually recognize a conductor pattern from front and rear surfaces of a printed circuit board by providing an opaque layer between the front and rear surfaces of the board and the pattern. SOLUTION: A circuit pattern 2 is formed on the printed circuit board 1, and insulating layers 4 are formed on both the surfaces. Insulating layers 4A, 4B disposed on front and rear surfaces of the board 1 are made opaque, and hence an opaque layer is formed between the inner patterns. In this case, as a means of making the layers 4A, 4B opaque, the insulating layers themselves are formed by coating other insulating layer formed of opaque material with opaque paint, so that the pattern cannot be recognized visually from the front and rear surfaces of the board.

Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To improve the yield of semiconductor wafers in an etching treatment. SOLUTION: An etching apparatus comprises a vacuum treating vessel 4 shut off from the outside 18 to be capable of forming a vacuum atmosphere inside 4a, means 7 for evacuating the vessel 4, means 5 for feeding a treating gas 13 in the inside 4a of the vessel 4, a sample holder 2 which supports a semiconductor wafer 1 and acts as an electrode, a counter electrode 6 for generating a plasma 12 in the inside 4a of the vessel 4, and an insulative ring 3 which covers the periphery 1d of the surface of the wafer 1 supported on the holder 2 and faces at the holder 2.

Title: Photocatalyst, lamp and lighting appliance
Inventor: WATANABE TSUTOMU
IPC: B32B5/14
Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To dispense with high-temperature heating owing to an increase in membrane strength. SOLUTION: This photocatalyst is composed of a carrier layer 2 with silica particles dispersed densely on the base 1 side of the photocatalyst and dispersed sparsely on the surface side, and also a photocatalyst layer 3 consisting of titania particles with a smaller average particle diameter than that of the silica particles. In this case, the carrier layer 2 formed on the base shows a high adhesive strength to the base 1 as the silica particles are densely dispersed on the base 1 side, and shows an unevenness on the surface side as the silica particles are sparsely dispersed, and the photocatalyst layer 3 consisting of the titania particles tightly sticks to the uneven face. Thus it is possible to reduce baking temperatures because the strength of the membrane is high and as such, the photocatalyst need no longer be baked at high temperatures.

Title: Inspecting device for flow rate characteristic
Inventor: OZAWA KENJI
IPC: G01F1/00
Filed: 1999-11-29
Abstract: PROBLEM TO BE SOLVED: To provide a flow rate inspecting device which can accurately measure and decide a flow rate conforming to an actual use state without deforming nor flawing a body 2 to be inspected when measuring the flow rate. SOLUTION: An inspected fluid supply part 4 is provided with a movable body 7 which is held slidably and the movable body 7 is pressed against the body 2 to be inspected with the pressure of inspection fluid. Consequently, only a small load is placed in a connection state and the whole body 2 to be inspected elastically deforms with the pressing load, so that an opening valve quantity does not vary. No elastic seal member is used for a connection part, so a misdecision due to a component defect or seal defect resulting from flawing at the time of the connection is not made. Here, the axial pressure reception area of the movable body 7 is equal to the pressure reception area of the body 2 to be inspected in an actual use state. Consequently, the body 2 is pressed and sealed with pressure conforming to the actual use state at the time of measurement.  The flow rate conforming to the actual use state can accurately be measured and decided.

Abstract: PROBLEM TO BE SOLVED: To surely record a subject at a desired time point while reducing power consumption. SOLUTION: The subject fetched at a previous time and the subject fetched currently are stored being divided into plural blocks. Both subjects are compared (step SA7) and it is discriminated whether a block having no change exists among the plural blocks or not (step SA8). When one block or more having no change exists, both two cases are supposed, one leaving the camera while keeping its power on or the other one trying to waite for a shutter opportunity taking the camera in the fixed direction by a user are estimated. Then, processing after SA10 is performed to discriminate these both cases. When a block counter counting how many times each block continuously has no change shows a value more than a prescribed number as a result of discrimination in a step SA14, it is regarded the camera is left keeping its power on, and a power source 1 is turned off (step SA15).
