Filed: 1984-02-14
Abstract: PURPOSE:To manufacture easily a thin sheet of hard-processable and high viscous resin, by a method wherein the inner surface of an extruder die is lubricated with lubricant and two or more kinds of thermoplastic resinous foundations which are nonadhesive to each other are extruded in multilayer of more than four tiers. CONSTITUTION:The inside surface of an extruder die 11 is lubricated by pouring a lubricant from a pump P. Resin which are nonadhesive to each other are extruded from extruders 12, 13 in multilayer of more than four tiers by a resin distribution part 14, said multilayer sheet is thinned by a B part of the extruder die 11, which is made to deform wide, temperature adjustment is performed through cooling by a C part, and the obtained multilayer sheet is separated and made into a thin sheet 17.

Title: Control method of copying machine
Inventor: OGURA MASAAKI
IPC: G03G15/00
Filed: 1980-02-28
Abstract: PURPOSE:To prevent excessive copying by generating a sheet-number over signal when the sheets of copies set to a copying machine exceeds those of which an additional device can store. CONSTITUTION:As the power source is put to work with the sorter connected to the copying machine, sorter number signals D0 and D1 are sent from the sorter to coder 7. With ten keys, etc., of the copying machine, sheet-number set signal S1 is inputted to set counter 4 to store the number of copy sheets. Consequently, encoded signal SET C from set counter 4 and coder output signal BIN NO from coder 7 are inputted to discriminating circuit 8 and when signal SET C is greater than signal BIN NO, output ''1'' is generated and inputted to one input of AND circuit 9. When the copying machine is in sort mode, signal S2 has value ''1''. Therefore, sheet number over signal S3 outputted by AND circuit 9 is held at ''1'' and a copy start, for example, is inhibited. Thus, excessive copying can be prevented.

IPC: F17C11/00
Filed: 1981-02-21
Abstract: PURPOSE:To use as fuel for a portable cooking stove or the like by filling an inflammable liquefied gas absorbed by pulp powder into a spray container. CONSTITUTION:An inflammable liquefied gas absorved by pulp powder is filled into a spray container. When the evaporated gas is spouted out of the nozzle of the spray container, the liquefied gas is evaporated under a normal temperature, and the gas is continuously spounted leaving the pulp powder in the spray container. In addition, even if the spray container is tumbled by mistake, such an waste or danger is unlikely that the liquefied gas flows out. The pulp powder is made of fibers with a length of about 0.8-2.7mm. at the center, therefore, the  total surface area becomes considerably large, and much liquefied gas can be absorbed.

Title: Hydraulic pressure control valve
Inventor: TAKIMOTO TADAO
IPC: B60T11/18
Filed: 1982-02-18
Abstract: PURPOSE:To prevent the vapor lock of a drum brake in a hydraulic pressure control valve for preventing the rear wheel lock by sealing the hydraulic pressure to be applied to the rear wheel cylinder through the contact of a plunger and a sealing means and applying residual pressure to the rear wheel cylinder while the cylinder is not being braked. CONSTITUTION:When the hydraulic pressure from a master cylinder is reduced due to the release of a brake pedal, a plunger 2 is let to fall by the force of a proportioning spring 4. Besides, when the hydraulic pressure from the master cylinder is reduced to the hydraulic pressure that corresponds to the spring force of a residual pressure setting spring 12, the plunger 2 is pushed to a sealing means 8 by the force of the residual pressure setting spring 12 and disconnects a flow path to the rear port 9. As a result, even when the hydraulic pressure from the master cylinder is reduced to zero, the hydraulic pressure of the rear wheel is not reduced below the hydraulic pressure that corresponds to the force of the spring 12 and the residual pressure can be applied to the rear wheel cylinder during non-braking period.
