Title: Continuous manufacture of thermoplastic synthetic resin stretched pipe and device thereof
Inventor: YONEDA RYUICHI
IPC: B29C55/24
Filed: 1990-05-14
Abstract: PURPOSE:To easily realize the radially stretching of extrusion-molded synthetic resin pipe by a method wherein two enclosed bodies are brought into close contact with the inner surface of extrusion-molded pipe so as to radially stretchingly deform along the inner surface of an outer mold by forcing pressurizing fluid in the inner surface of the pipe and, after being radially stretched, the pipe is cooled and hardened and the enclosed body on the side at the end of the radially stretching of the pipe is expandingly deformed so as to be brought into contact with the inner surface of the extrusion-molded pipe at constant contacting pressure. CONSTITUTION:Thermoplstic synthetic resin is tubularly extrusion-molded from a forming die 2 so as to introduce the extruded end P' of pipe through a controlling device 3, a radially stretching mold 4 and a cooling device 5 to a pulling device 6. Under the condition that pulling force is acted on extruded resin with the pulling device 6, fluid is forced in enclosed bodies 8A and 8B and a space S between the bodies so as to expand the enclosed bodies 8A and 8B in order to bring them in close contact with the inner surface of the pipe P and, at the same time, pressurize the space S, resulting in applying pressure in the pipe P so as to radially stretchingly deform the pipe P along the inner surface of a radially stretching outer mold 4. When extrusion proceeds and the radially stretched part of the pipe is cooled and hardened by the cooling device 5 and reaches the rear end side enclosed body 8B, the rear end side enclosed body 8B starts to expand along the inner wall of the pipe P by the pressure, which is continuously applied in the interior of the body 8B, so as to continue to radially stretchingly deform the pipe P by the constant inner pressure by keeping the space S under enclosed state.

Title: Horizontal drive circuit
Inventor: YAMADA TAKEO
IPC: H04N3/16
Filed: 1984-06-18
Abstract: PURPOSE:To reduce power loss by providing a circuit stopping power supply voltage of a horizontal drive circuit after a horizontal output circuit is driven in a conventional horizontal drive circuit. CONSTITUTION:The conventional drive circuit is provided with a circuit 18. A voltage generated in a ternary winding of a flyback transformer is fed to a terminal in a form of a rectified smoothing voltage. When a power supply voltage is fed to a terminal 2, a drive transistor (TR) 7 and a horizontal output circuit 3 are driven. Since the circuit 3 is driven, a flyback pulse is generated, a voltage is generated to the terminal 14 and a TR13 is conducted. Then a TR12 is turned off. Although the power supply to the horizontal drive circuit is stopped, the horizontal drive circuit is kept driving with charge/discharge of a capacitor 4. In increasing the resistance value of resistors 9, 10, 11, the loss is small and the loss in a resistor 8 is eliminated completely.
