Title: T-die type plastic covering method of steel pipe
Inventor: INOUE YOSHIHIKO
IPC: B29C63/10
Filed: 1983-02-22
Abstract: PURPOSE:To obtain the titled covered steel pipe, by blowing a hot air current against a melted plastic belt so that the melted plastic belt is forcibly united to the outer circumferential surface of a steel pipe that is rotatably fed, the bonding strength being stable even if the steel pipe has any stepped parts. CONSTITUTION:In case a steel pipe 4 is rotatably fed continuously, and a plastic belt 2 that is extruded from a T-die 1 and is in a melted or semimelted state is forcibly united onto the outer circumferential surface of the steel pipe 4 so that a plastic cover 6 may be formed, air 9 is dehumidified by a drier 10, is compressed by a pressure compensating circuit, and is heated by a heater 12 to obtain a high pressure hot current. The high pressure hot current is jetted from an air curtain nozzle 7 generally toward the axis of the steel pipe 4 so as to cause the plastic belt 2 to be forcibly and uniformly united to the outer circumferential surface of the steel pipe 4 so that the intended plastic-covered steel pipe may be obtained.

Title: Bath tub hot water circulation valve disk
Inventor: MIURA HIROTAKA
IPC: F24H9/12
Filed: 1989-02-07
Abstract: PURPOSE:To improve the heat insulating efficiency of hot water in a bath tub and prevent the generation of troubles in a circulation pipe by installing a valve disk on a bath opening of said circulation pipe between the bath tub and a heat exchanger and laying out a shape memory alloy which opens and closes a cap between the shaft of this valve disk and the valve disk body and a pressure release hole above the cap. CONSTITUTION:A shape memory alloy-made coil spring 4 is under a contracted state while a cap 1 is closed when the temperature of hot water in a bath tub is proper to take a bath, which allows the warm water heated by a pilot light to flow into the bath tub from a pressure release hole 11 of the cap 1. When the bath tub is cooled inside, a gas burner is ignited by the pilot light so that the hot water in a circulation pipe may be heated and discharged from the pressure release hole 11 at first. When the temperature of the hot water in the circulation pipe is raised and reached the transformation temperature of the shape memory alloy, the coil spring 4 is restored to its original shape so that the cap 1 may be pushed open, thereby heating the temperature of the hot water in the bath tub. When it rises to a proper bath temperature, the cap 1 is closed again. This construction makes it possible to provide excellent insulation efficiency and prevent the generation of troubles in the circulation pipe as well.

Title: Production of solid-state image pickup element
Inventor: FURUKAWA TAKAO
IPC: H04N9/07
Filed: 1987-02-09
Abstract: PURPOSE:To prevent blurring of colors by dispersion of light by providing color filters constituted of individual filters formed of photosetting or thermosetting resins and dyes. CONSTITUTION:The photosetting or thermosetting resin 4 is coated and the dye 5 is coated on the surface thereof. The dye 5 is fixed by exposing, developing or thermally curing the resin 4 and thereafter, the resin which is not exposed, developed or thermally cured and the dye thereon are removed. Since the color filter 6 can be formed into single layer structure in the above- mentioned manner, dispersion of light hardly arises between adjacent rays of color light and since the generation of light distortion is thereby obviated, the blurring of the colors is eliminated and the performance of this solid-state image pickup element is improved.

IPC: F28D20/00
Filed: 1984-02-17
Abstract: PURPOSE:To prevent an unevenness of the heat exchanging amount depending on the spot in a heat accumulating tank at the time of heat accumulation and release by making the aggregate opening area of a heat exchanging space near to an outlet of thermal medium smaller than that of a heat exchanging space near to an inlet. CONSTITUTION:A heat exchanging space is formed inside a casing having an opening 6, in which the heat is exchanged to and from a regenerating mass 8 as the thermal medium 9 flows. Said opening is divided into two thermal medium inlets 12, 13 and one thermal medium outlet 14, and said heat exchanging space is divided into two inlet side heat exchanging spaces 15, 16. As the inlet side heat exchanging spaces 15, 16 are made equal in area size, and their aggregate area of opening is made smaller than the opening area of the outlet side heat exchanging space 17, there is no unevenness of the heat exchanging amount depending on the spot in a heat accumulating tank at the time of heat accumulation and release.

Inventor: FUKAYA NORITAKA
IPC: F02M69/00
Filed: 1987-02-10
Abstract: PURPOSE:To prevent fuel from causing air bubbling by providing, between a valve body and a valve body holder, a back spring and a thermo-sensing spring composed of a shape memory alloy that elongates when the temperature exceeds a set point. CONSTITUTION:A valve body 33 is installed into the interior of a valve body holder 31 so that a sliding action is possible and thermo-sensing spring 34, composed of a shape memory alloy, is inserted into the interior of a valve body 33. A straight hole 35 is provided on the bottom of the valve body to introduce fuel to the circumference of the therms spring 34. A backs spring 37 is inserted between the sounder portion 33a of the valve body 33 and a stopper 36. Therefore, when the temperature exceeds the set point, the fuel pressure is controlled to be the second set pressure as the thermo-sensing spring elongates and the valve body displaces to a position contacting the stopper of the valve body holder. Thereby, air bubbling of fuel can be prevented.

Title: Contact sensor of prober
Inventor: OOSATO MORITOMO
IPC: H01L21/66
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To prevent a permanent deformation of a second sensor needle by a method wherein a torsion coil spring is provided in the second sensor needle comprising three sensor needles. SOLUTION: If a first sensor needle 20 comes into contact with a lead 28 of ICs, the first sensor needle 20 is deformed and comes into contact with a second sensor needle 22. Then, the second sensor needle 22 is also deformed and separated from a third sensor needle 24. Thus, a conduction between the second sensor needle 22 and the third sensor needle 24 is canceled, and this conductive cancellation is detected, whereby it can be informed that the first sensor needle 20 comes into contact with a lead 28. As a torsion coil spring 32 is provided in the second sensor needle 22, if the first sensor needle 20 is overdriven and the second sensor needle 22 is largely deformed, this deformation can be elastically absorbed by the torsion coil spring 32. Accordingly, a permanent deformation of the second sensor needle 22 can be prevented.
