Title: Thin-film magnetic head
Inventor: SAITO MASAKATSU
IPC: G11B5/31
Filed: 1990-11-30
Abstract: PURPOSE:To enable increase in magnetic reluctance at a connection part of a gap formation part and upper/lower magnetic layers to be restricted by bending an interlayer insulation layer at the gap formation part and the upper/lower magnetic layer connection part in a direction which is vertical to a plane of the gap formation part and the upper/lower magnetic layer connection part and by terminating one edge of the interlayer insulation layer at the plane. CONSTITUTION:An interlayer insulation layer 21 has one edge on a gap surface at a front core part, is extended in vertical direction to the gap surface from here, and is formed so that the interlayer insulation layer formation surface is twisted near a rear edge of the front core part and is nearly in parallel direction to the gap surface at the rear core part. Further, the interlayer insulation layer 21 is bent in vertical direction again toward a connection surface at an upper/lower magnetic layer connection part and is formed to be terminated at the connection part. On the other hand, an upper magnetic layer 6 is in double structure similarly and a width in track width direction is regulated by a width of a through-hole which is provided at a coil insulation layer 5 at the front core part, thus obtaining a multilayer structure of the upper/lower magnetic layers 6 and 2 without increasing magnetic reluctance.

Filed: 1988-12-28
Abstract: PURPOSE:To prevent not only the generation of a crack but also a lowering of life due to the aging of rubber even when the rubber of a carcass is exposed to the surface of a side wall by laminating a weather-resistant rubber layer as the outer layer of the rubber lining cord layer of the carcass of a green tire. CONSTITUTION:After a green tire 20 is mounted to a core mold element 12 through a tire mounting machine, the core mold element 12 is mounted on a lower mold element 11 and an upper mold element 10 is allowed to fall to clamp a mold. Next, unvulcanized rubber is injected in a cavity in the volume corresponding to a lug and the outside part of a side wall from a rubber injection port 21 to fill said cavity and integrally bonded to the green tire 20 to perform vulcanization under heating. An outer layer rubber lining cord layer 9 is formed by coating cords 4 with rubber 6 having good adhesiveness to the cords 4 in a thickness of 0.1 - 0.7mm and subsequently laminating weather- resistant rubber 8 having a thickness of 0.3 - 1.5mm to the cord layer to cover the same. The vulcanized one is cut into an appropriate length as a carcass ply and assembled along with a bead core on a cylindrical former and molded to obtain the green tire 20.

Title: Lens holding frame structure for lens device
Inventor: YOSHIDA SHIGERU
IPC: G02B7/02
Filed: 1996-12-10
Abstract: PROBLEM TO BE SOLVED: To obtain a photographing lens that is easy to design, can exhibit the performance of a lens sufficiently, and is inexpensive, by forming plural grooves having different depth corresponding to plural photographing lenses having different focal distance at a lens holding frame body. SOLUTION: Three pairs of grooves 54, 56, 58, 60, 62 and 64 having different depth corresponding to three kinds of lenses having different focal distance are formed at one lens holding frame 28. Thus, six grooves 54, 56, 58, 60, 62 and 64 for holding the lenses are formed at the same interval at the inner peripheral surface of the body 28. The grooves 54, 56, 58, 60, 62 and 64 are formed in parallel with the optical axis P, and the grooves opposed to each other by putting the optical axis P in between are formed so as to have the same depth. Thus, the totally three pairs of the grooves 54, 56, 58, 60, 62 and 64 for holding the lenses by taking two grooves as on pair are formed on the inner peripheral surface of the lens holding frame body 28.  Thus, the need of forcibly designing the photographing lens is eliminated though the lens holding frame 28 is made in common, so that the design of the photographing lens is made easy.

Abstract: PURPOSE:To enable the absorption of the torsional vibration of a power transmission for the viscosity change of oil by providing a friction disc and a shape memory alloy spring in a friction generation means installed between an inner hub and an outer hub for changing friction, depending upon a temperature change. CONSTITUTION:A friction generation means 70 is provided between sub-plates 24 and 25 forming a part of an outer hub 22, and an inner hub 21. The friction generation means 70 has a pair of right and left friction discs 71 and 71, and an annular shape memory alloy spring 73. This spring 73 energizes both friction discs 71 and 71 with a friction load, and the transformation temperature of the spring 73 is set near the temperature where oil viscosity becomes equal to or above the predetermined value. Namely, high friction load is applied to the discs 71 and 71 at a temperature lower than the transformation temperature, while a low friction load is applied to the discs 71 and 71 at a temperature higher than the transformation temperature. According to the aforesaid construction, when oil temperature in a transmission changes, the torsional vibration of a power transmission system is absorbed during the relative turn of both hubs 21 and 22, thereby improving quietness in a car.

Abstract: PURPOSE:To accurately measure frozen goods and prevent overflowing from canned containers in a canning process, by preventing steam of frozen goods due to thawing thereof by supplied hot liquid from permeating into a mechanism of a combined measuring device by means of a gate in a chute. CONSTITUTION:A required volume of hot liquid is fed from shutter nozzles 31 of a hot liquid feeder 26 to the upper part of a cone 2 of frozen food staffs filed previously in a chute 30 to thaw out them. Meanwhile, air-cylinders 29 move forward to close a gate 27 at the upper part of a storage chute 20 and a feed chute 28.

The volume of the thawed cone and hot liquid are previously measured to coincide with the can volume. As a result, at the time of completion of feed, the upper meniscus becomes level with the upper of the canned container 1 to securely charge just a specified volume.

Title: Reinforcing method of cylindrical column
Inventor: OSUGA TETSUO
IPC: E04C3/36
Filed: 1995-12-19
Abstract: PROBLEM TO BE SOLVED: To prevent buckling without bringing demerits like defects of the appearance or increase of the foundation load, by injecting a foaming material into the inside space of a cylindrical wall vertically extending and closely sticking the foamed body made of the foaming material the inside face of the cylindrical wall. SOLUTION: An injection hole for a foaming material is formed at the upper end of the cylindrical wall 1 of a cylindrical column 10 and a liquid foaming material 15 is infected from the infection hole into the inside space S1 of the cylindrical wall 1. After the injection, the foaming material 15 expands in the inside space S1 to form a foamed body 16. And then, the external face of the foamed body 16 is closely stuck to the inside face 2a of a steel plate 2 defining the inside face of the cylindrical wall 1. Accordingly, since the foamed body 16 charged in the cylindrical column 10 supports with a uniform pressure the inside face 2a of the steel plate 2, a high preventive effect against buckling is brought out.  And since the specific gravity of the foamed body 16 is remarkably smaller than the concrete, and the weight of cylindrical column 10 increases only a little, the cylindrical column 10 imposes the load only a little to the foundation. And further, the external face of the cylindrical column 10 shows almost no change and hence, no defect is brought in the external appearance.
