Title: Production of core for cylindrical coil
Inventor: KURIYAMA KIYOSHI
IPC: H01F38/12
Filed: 1998-01-08
Abstract: PROBLEM TO BE SOLVED: To improve the packing efficiency and yield rate of a material. SOLUTION: In producing a core for a cylindrical coil which is produced by laminating a variety of single plates which differ in widths, band steels 5 which have the width of these single plates are prepared by cutting in strips, corresponding to respective single plates, and these strips steels 5 are made to pass though stepped grooves 10a, 11a, 12a of three pairs of rolls 10, 11, 12 which are arranged in a longitudinal direction and are laminated. The trip steels 5 in a laminated form which are feed from the rolls 12 are cut in a given length by a cutter 6, while being fixed by fixing jigs 13, 14, while the cutting faces are welded in a laminated direction of the strip steels 5.  Even if the iron core is multistaged, the production apparatus is prevented from becoming large- sized and the increase of a scrap amount can be also restricted, thus enabling production of laminated iron cores having high packing efficiency at a high yield rate.

Filed: 1998-01-09
Abstract: PROBLEM TO BE SOLVED: To allow pressing force to act on a third seal part to prevent deformation of a second seal part so as not to come closer to a starting motor by forming an inclined pressing surface on a casing of the starting motor, and forming an inclined pressure receiving surface which is brought into contact with the pressing surface on the third seal part of a gasket. SOLUTION: When the front bracket 32 of a starting motor 18 is joined with a first joining surface 98, a first seal part 120a is crashed, a third seal part 120c is deformed so that it may come closer to the starting motor 18, a pressing surface 117 of the front bracket 32 is brought into contact with a pressure receiving surface 118 of the third seal part 120c to allow pressing force to act. In this case, since the pressing surface 117 is inclined downward to an engine main body 15 side, pressing force is allowed to act on the third seal part 120c so as to prevent deformation of the second seal part 120b so that it may not come closer to the starting motor 18. An operation for returning the second seal part 120b to a normal position is eliminated when an electromagnetic driving unit 19 is joined.

Abstract: PURPOSE:To improve the heat exchanging efficiency of a heat exchanger further by employing heat transfer tubes having a plurality of inflated sections in the lengthwise direction thereof. CONSTITUTION:An oil cooler 1 is equipped with a corrugate tube 3 formed of a plurality of inflated sections 2 in the lengthwise direction thereof. The inner surface of the corrugate tube 3 is provided with a wave form, symmetry to an axis, by respective inflated sections 2 whereby the surface area of the corrugate tube 3 is increased by the waveform and turbulent flow is generated near the inner wall of the corrugate tube 3.
