Title: Electrical caulking method
Inventor: MATSUI HITOSHI
IPC: B21D39/00
Filed: 1983-05-20
Abstract: PURPOSE:To prevent loosening between works after electrical caulking by supplying AC power to plural metals and caulking the metals by the pessurizing force exerted thereon. CONSTITUTION:The frequency of a power source 24 is determined by taking materials, etc. of a casting material 16 and a shaft material 20 into consideration. The AC power of the power source 24 is supplied to a lower electrode 18 and an upper electrode 22. The material 20 pressurized by the lower electrode 18 and the upper electrode 22 deforms then the material 20 contacts the material 16 and the current flowing in the material 20 is shunted to the material 16. The current shunted in the material 16 is passed through the surface side of the material 16 by the surface sking effect. The temp. of the material 16 is consequently quickly increased to the temp. higher than the material 20 so that the material 16 cools down faster and shrinks more largely than the material 20 in the cooling stage after the end of the current conduction. The material 20 and the material 16 are thus joined by strong binding force. The material 20 and the material 16 are powerfully bound even after cooling without loosening on the fitting surfaces of the two materials.

Title: Multi shaft cooling device
Inventor: INOUE HITOSHI
IPC: B23Q11/14
Filed: 1982-05-26
Abstract: PURPOSE:To averagely cool bearings, by connecting one of the vapor or liquid pipes in both main shaft devices, equipped with each of a hollow chamber sealing working liquid in the inside of the two bearings and a heat radiator communicated to said hollow chamber through the vapor and liquid pipes, to the other heat radiator. CONSTITUTION:If temperature of two bearings 3 is increased higher as compared with the temperature of a similar bearing 31, an evaporation amount, vapor pressure and temperature at vaporization of working liquid in a hollow chamber 7 increase as compared with those levels in the other side, consequently a larger amount of the latent heat of vaporization is removed and the bearing 3 is more cooled, and temperature of the bearing increasing higher than the temperature of the other bearing 31 can be suppressed. Then vapor at high temperature vaporized in the chamber 7 moves to a heat radiator 81 via a vapor pipe 10, here temperature of the condensed liquid is higher as compared with the temperature of liquid condensed in a heat radiator 8, and the liquid flows into a hollow chamber 71 via a liquid pipe 121. Accordingly, temperature of the bearing 31 increases by the higher degree of liquid temperature, and a difference of temperatures between the both bearings 3, 31 can be suppressed smaller.

Abstract: PURPOSE:To contrive to shorten the total production time of a sheet and at the same time reduce the development of locally thin portions and wrinkles by a method wherein the extrusion molded thermoplastic sheet is preformed by being held along a preforming surface through suction in the midway during the process to carry the sheet to a stamping machine. CONSTITUTION:In a conveying means 5 for preforming, a preforming surface 23, which is heated by a heater 20 so as not to lower the plasticity of a resin sheet 10, sucks and holds the resin sheet 10 by vacuumizing through a pipe 26, a hollow portion 24 and holes 25 with a carrier 17, which is positioned above and lowered onto a belt conveyer 4. After that, the carrier 17 under the state that the resin sheet 10 is held thereon is raised and pivoted so as to be shifted toward a stamping machine 6 in order to be lowered at a position above a bottom force 29. At that time, because air is sent to the preforming surface 23 by changing over a changeover valve 27, the resin sheet 10 is seated onto the bottom force 29. During the conveying process as mentioned above, the resin sheet 10 is preformed to the state following the mold surface of the stamping machine 6 by being sucked and held onto the preforming surface 23.
