Title: Heater control system for facsimile receiver
Inventor: IWAKABE FUYUKI
IPC: H04N1/29
Filed: 1980-05-13
Abstract: PURPOSE:To obtain an excellent received picture, by controlling the period of lighting according to the moving speed of a recording paper and controlling the lighting time through detecting the temperature in a terminal fixing device, in a fascimile receiver of electrostatic recording system. CONSTITUTION:When a recording paper advances by a certain distance, a heater lighting control section triggers the output A of a counter 2 to decide the lighting time of the heater. Thus, when the speed of a recording paper is variable, the lighting time can be decided in synchronizing with the moving speed. An output C of a heater lighting control section 3 lights the heater in a thermal fixing device 5, and a temperature near the recording paper during fixing is detected at a temperature sensor to feedback it to the heater lighting control section. Thus, the lighting time of the heater is determined. Then, excellent received picture can be obtained without insufficient fixing and carbonization on the paper sheet.

Title: Production of phenolic resin
Inventor: YOSHIMITSU TOKIO
IPC: C08K5/20
Filed: 1982-04-15
Abstract: PURPOSE:To obtain in a high yield the titled resin which gives decorative laminates capable of bend processing at a relatively low temp. when impregnated therewith, by mixing epsilon-caprolactam with a reaction product obtd. by reacting phenol with formaldehyde in two steps. CONSTITUTION:Phenol (A) is reacted with formaldehyde (B) in a molar ratio of A to B of 0.3-0.6. Then the compd. B is added to the initial reaction product in such a proportion as to give a molar ratio of A to B of 0.9-1.3. The mixture is reacted to obtain a reaction product. 5-30wt% (based on the solid weight of the reaction product) epsilon-caprolactam (C) is mixed with the reaction product to produce the desired phenolic resin. Since the molar ratio of B to A in the first stage reaction is low, the amounts of unreacted compds. are small. Further, by reacting with an additional amount of compd. B, the reaction product can be obtd. in a high yield. By mixing with compd. C, the resulting phenolic resin can be plasticized without reducing its characteristics and decorative laminates obtd. therefrom can be post-formed at a low temp.

Abstract: PURPOSE:To eliminate defective position of a cathode, by folding the circumference of disc-shape seal component fitting the cathode more shallowly than the thickness of the end of a magnetic pole, and sealing the anode end flange bent to be contacted on this circumference with welding. CONSTITUTION:A folding depth (h) of a circumference 2a of a disc-shaped seal component 2 fitting a cathode (not shown) of a magnetron at the center is made slightly smaller than the thickness (t) of the end of a magnet pole 4.
