IPC: B29C67/20
Filed: 1986-03-04
Abstract: PURPOSE:To manufacture an MPFR molded article, in which a thermal stabilizer and its pyrolyzed matter are not contained substantially, without causing heat deterioration, by a method wherein melt molding of hot-melt fluorine resin MPFR is performed by making use of a mold wherein a mold release layer and the thermal stabilizer of the MPFR are formed. CONSTITUTION:A coating layer of a mold release agent and that of a thermal stabilizer of hot-melt fluorine resin are stratified respectively in one or more layers on the surface of a mold and hot-melt molding is applied to the hot-melt fluorine resin by making use of the mold. Stratification of every layer is performed by applying the thermal stabilizer or the mold release agent which is in a state of a solution or a dispersed fluid to the layer by brushing or spraying. A mold release agent may be compound with the thermal stabilizer layer. Before molding under especially severe terms, a small quantity of the thermal stabilizer may be compounded with MPFR within a sphere not exerting a harmful influence on a molded article. As a molding method, blow molding, transfer molding, injection molding and Roto molding can be applied.

Filed: 1983-03-19
Abstract: PURPOSE:To prevent flickering in the horizontal direction of a picture by irradiating always a horizontal synchronizing sensor with the optical beam having an equal intensity in accordance with a signal from an optical beam detector. CONSTITUTION:While an optical beam 100 scans between a horizontal synchronizing sensor PD1 and an optical beam detector PD2, the output from a counter 12 is taken in and is inputted to a switch 9. A voltage corresponding to each face of a rotary polyhedral mirror 5 is taken out from a voltage generating part 8 and is sent to a VCO10, and a fall angle correction corresponding to each face of this mirror 5 is performed. While scanning is transferred from the detector PD2 to the next mirror face and passes the sensor PD1, a certain voltage is sent to the VCO10 to irradiate the sensor PD1 with the optical beam 100 having an equal intensity. The variance of the timing pulse due to the variance of the rise time of the horizontal synchronizing sensor PD1 is eliminated, and flickering in the horizontal direction of the picture is prevented.

Title: Valve for high temperature and high pressure gas containing dust
Inventor: OOTAWA KIMIAKI
IPC: F16K25/04
Filed: 1980-04-14
Abstract: PURPOSE: To prevent damage on the surface of a seal member, gas leakage and the like, by detecting during closure of a valve a level of water enclosed in the upper space between the valve body and seal member in order to control opening/closing of a water supplying valve.  
     CONSTITUTION: When a valve body 2 is separated from the surface of a seal member 5, that is, a valve is opened, a high temperature and high pressure gas containing dust is introduced into a valve casing, while the dust is captured by a demister 6 and the water sprinkled by spray 1. In this case, since the surface of the seal member 5 is protected by the water splinkled by spray 1, it is not susceptible to damage. When the valve is closed, the water splinkled by the spray 1 is enclosed on the upper part between the valve body 2 and the seal member 5. Here, the level of the enclosed water is detected by a level detector 7, where a detected signal is transmitted to a driving device 8 of a water supply valve while opening/closing is controlled to the wafer supply valve 9. As a result, the enclosed water is maintained at a prescribed level thereby preventing gas from being leaked.
