Filed: 1986-07-09
Abstract: PURPOSE:To automatically select the right subscriber's circuit corresponding to a telephone and to reduce the mistakes of a construction by providing a switching unit and its control circuit between the telephone or a terminal and subscriber's circuit groups. CONSTITUTION:If a telephone set 101 is a digital telephone set or an electromagnetic type telephone set which is in an off-hook state, a current flows from a direct current power source 202 and the current is detected in a DC detection circuit 213, then the signal is transferred to a control circuit 105. If a synchronism isn't led-in in a specified time (about one second) the control circuit 105 inverts the signal given to the terminal 210 and makes pingpong system digital subscriber control circuit 207 side work. Moreover if the synchronism isn't led-in in a specified time the telephone 101 decides that the electromagnetic type telephone set is in the off-hook state and inverts a switching unit 102 so as to connect the telephone 101 to an analog subscriber circuit 104. After that, the control circuit 105 decides that the telephone 101 is the electromagnetic type telephone set and keeps the state, so that the switching unit 102 is kept in the state connecting the telephone 101 to the analog subscriber circuit 104.

Abstract: PURPOSE:To contrive the great reduction of dark currents, by polishing the surface of a layer insulating film flat, when providing a photoconductor film as a photoelectric conversion means on a semiconductor substrate wherein an MOS element for a scanning means is incorporated. CONSTITUTION:The insulator 18' of SiO2, etc. is deposited on an FET thicker than the surface unevenness of the MOSFET as the scanning means, and then the surface thereof is polished by the impalpable powder of Ce oxide, etc. resulting in a flatness.

Title: Injection molding method
Inventor: ONO TSUKASA
IPC: B29C45/73
Filed: 1983-09-02
Abstract: PURPOSE:To contrive to improve the productivity and dimensional accuracy of product and to prevent the defective external appearance from developing by a method wherein mold temperature is controlled by supplying hot water and cooling water alternately in the medium passage of a mold. CONSTITUTION:Just before the mold opening, the outside air is led in a medium passage 2. Just after the mold opening, the circulating loop of hot water is formed by actuating changeover valves 5 and 6 so as to communicate a valve port 5a to a valve port 5d and a valve port 6a to a valve port 6c. The hot water is kept on supplying to the medium passage 2 in order to heat a core 1 by the suction of a pump 7 in the circulating loop. The heating of the core 1 is continued during the period ranging from after the taking-out of a product through the closing of a mold to just before the finish of filling of resin. Because the temperature of hot water is set so as to keep the surface temperature of the core above the dew point, no dew condensation is developed on the core. In addition, because the surface temperature of the core at the filling of resin is enough high, the filling speed can be increased.
