Title: Injection molding
Inventor: SUGIMOTO SHINJI
IPC: B29C45/34
Filed: 1988-10-03
Abstract: PURPOSE:To prevent molding failure from developing by a method wherein molten resin material is injected in the product part space of a closed mold and the gas in the product part space is sucked outside in order to evacuate the product part space in the midway of the injection process of the resin material. CONSTITUTION:After mold closing, resin material P is injected and simultaneously an evacuation starting delay timer is put into actuation. Needless to say, the injection time of the resin material P is controlled by separate injection timer. Though the viscosity of the resin material P just after the start of injection is low and bubbles in the material, gas component discharged from the material itself or the like is under the easily expandable and diffusible state, since the pressure in a product part space R becomes higher than the atmospheric pressure by the injection of the material, no development of molding failure results due to the suppressing effect of said higher pressure. After the start of injection, the reaction of the resin material P continues and the viscosity of the material becomes higher. At the time, when the resin material P fills about one-third of the product part space R, the time of the evacuation starting delay timer is up and simultaneously an evacuation timer, which controls evacuation time, is put into actuation. As a result, the vacuumization of the product part space R is started through an air vent hole 8 with an vacuumizing device. When the time of the evacuation timer is up, the evacuation is stopped.

Abstract: PURPOSE:To effectively suppress the disturbing wave generated from terminal lines of an IC element by coiling at least two band-shaped power supply conductors tubularly with a band-shaped insulator between them and connecting first and second lead lines to terminal lines of the IC element. CONSTITUTION:Noise filters FB1 to FBn are connected in series to power lines of an IC element 20. Noise filters FD1 to FDn are connected in series to its signal lines D1 to Dn. Then, the power supplied through power lines B1 to Bn is certainly supplied to the IC element 20 through filters FB1 to FBn, and its noise component is removed. Signals inputted to and outputted from the IC element 20 through signal lines D1 to Dn pass filters FD1 to FDn. Consequently, various frequency components flowing on terminal lines of the IC element are effectively suppressed because noise filters function as distributed constant type LC composite circuits.

IPC: H01L21/26
Filed: 1992-09-18
Abstract: PURPOSE:To provide a sample processed without a variation in electric characteristics in an anneal lamp system, by preventing a variation in thermal treatment at a wafer face, in which a reactive gas at a room temperature causes a heated wafer to be cooled in a chamber. CONSTITUTION:Before a heat-treatment reactive gas is supplied to a chamber 5, the reactive gas is passed through a gas heating chamber 9 at a temperature controlled by a heater 8, a temperature controller 11, and a thermocouple 10 so that the reactive gas is heated up to or near to a given temperature. Then, even when the reactive gas reaches the wafer 4 heated in the chamber 5, the reactive gas doesn't cause the wafer 4 to be cooled. Consequently, a uniform distribution in temperature at the wafer 4 and a uniform amount of heat treatment can be realized.

CONSTITUTION:Primary air is induced into a Venturi tube 4 by the jet of gas supplied from a nozzle 2 to be converted into a mixed gas which is supplied to a burner port part 6 after being evenly distributed by a strainer 5. A primary flame 14 is formed above the burner port part 6 by combustion, and a secondary flame 15 is formed above the primary flame 14. A high-temperature zone is usually formed in the secondary flame 15 as is well-known; however, since secondary air 16 is supplied deep into the central part of the secondary flame 15, as shown by the arrow, along the inclination of a burner port member 7 by projecting the burner port member 7 so as to be formed into a substantially angular shape and by partitioning a main burner port 11 with stable-flame holding parts 8, the formation of the high-temperature zone can be prevented. In addition, since a small amount of the mixed gas is supplied to auxiliary burner ports 12 provided on the stable-flame holding parts 8, the fuel is burnt at an early stage in a small flame, and since the combustion gas generated thereby is supplied to the flame formed on the main burner ports, a temperature in the high- temperature zone is further lowered.
