Filed: 1981-04-22
Abstract: PURPOSE:To make a stable, continuous production of extremely thin film without generating breaks and pinholes by stretching or rolling an extruding multilayer film having two layers of thermoplastic resin free from thermal weldability and then delaminating these two layers. CONSTITUTION:Coextruding multilayer film or extruding lamination multilayer film having the 1st thermoplastic resin layer capable of stretching and rolling and the 2nd thermoplastic resin layer capable of stretching and rolling which does not conduct thermal welding into this 1st resin layer are stretched and/or rolled uniaxially or biaxially and then the 1st resin layer is delaminated from the 2nd resin layer. Regarding the elongation of above-said original film there are thought lengthwise or breadthwise uniaxial stretching, instantaneous lengthwise-breadthwise biaxial stretching, progressive biaxial stretching, lengthwise uniaxial or lengthwise-breadthwise biaxial rolling and these combinations. The best elongation method is selected according to uses of the extremely thin film obtained. Usually, 2-50 times are given to magnification of elongation.

Filed: 1979-05-23
Abstract: PURPOSE: To achieve reduction of manufacturing cost and increase of hardness by shaping a thick pipe or plate having proper hardness into a combination body of a compressor and a groove, thereby eliminating need for preshaping or both of it and finishing.  
     CONSTITUTION: A steel pipe is shaped into a cylinder 10a which contains both of a bore 22a and a groove 14a. As material of the steel pipe has high strength, each wall 28a, 29a is allowed thinner than a conventional product. Deforming the steel pipe makes its material grow harder than the prefinished steel pipe. Resulting higher hardness of the work can save thickness of the steel pipe, thereby to reduce material cost. Precisely forming the steel pipe can eliminate need for finishing as well as preshping of a bore 22a, edge face 26a and groove 14a. Both advantages of achieving low manufacturing cost and high hardness can be obtained.

Abstract: PURPOSE:To reduce cost and to simplify the circuitry by utilizing a paper detecting photo-sensor mounted on a carrier for detection of a paper and the hole position of the carrier. CONSTITUTION:Upon movement of a carrier 21 to the home position, a light transmitter 31 is arranged at a position facing with the light receiving section 27B of a paper detecting reflection type photo-sensor 27 and a block member 32 having a slit 32A for limiting the width of light transmitted from the light transmitter 31 is arranged between the light transmitter 31 and the photo-sensor 27. When a paper is detected, a CPU 41 turns the light transmitter 31 OFF while turns the light transmitting section 27A of the photo-sensor 27 ON, thus judging whether or not the output from the light receiving section 27B is '1'. When the output is '1', it means existence of paper while output of not '1' means exhaustion of paper. When the home position of the carrier 21 is detected, the light transmitting section 27A of the photo-sensor 27 is turned OFF and the light transmitter 31 is turned ON/OFF three times, thus recognizing arrival of the carrier 21 to the home position on condition that a correct signal is fed from the light receiving section 27B under this state.
