Filed: 1978-11-10
Abstract: PURPOSE: To obtain a lined metal pipe with reduced amout of residual air existing between the inside wall of the pipe and a coat layer by sequentially heating a metal pipe, into which a thermoplastic synthetic resin tubular member is inserted, from a position between the pipe ends toward the pipe ends and adhering under pressure the tubular member to the inside surface of the pipe.  
     CONSTITUTION: A metal pipe is which a thermoplastic synthetic resin tubular member closed at both ends is inserted is sequentially heated from a position between its ends toward its ends, and the tubular member is adhered under pressure to the  inside surface of the pipe by fusion welding or adhesion or through an adhesive. As  the metal pipe, one made of steel, aluminum, or zinc-plated metal is used; the inside surface of the pipe is preferably clarified by pickling or the like before use. Prior to the insertion of the tubular member into the metal pipe, an adhesive layer may be formed on the outside surface of the member or the inside surface of the pipe.

Title: Conveyance device for sheet
Inventor: NAKAMURA KUNIHIKO
IPC: B65H3/64
Filed: 1979-10-25
Abstract: PURPOSE: To feed out laminated sheets correctly piece by piece by stopping a rotary drum when a tip in rotary direction of suction aperture has come to a position opposite to the edge in transfer direction of the laminated sheets.  
     CONSTITUTION: The rotary drum 29 is caused to turn intermittently and when the tip in rotary direction of suction aperture 30 has come to the position opposite to the edge in transfer direction of the laminated sheets 25, the rotation of rotary drum 25 is suspended. As a result, it is possible to stabilize suction and at the same time, prevent generation of suction failure. Also it is assured that the tip of sheet will be sucked into rotary drum 29, and there will be no fear that the tip may be bent. For these reasons, laminated sheets can be fed out piece by piece.

IPC: G01N27/00
Filed: 1978-11-11
Abstract: PURPOSE: To obtain the position of the center of gravity of vertical distribution and the surface  density of charge trap center from the variation of the current-voltage characteristics, by producing the electron and positive hole pairs through the irradiation of electron rays on the surface of insulation film of MOS construction and measuring the current-voltage characteristics through the  metal electrode applied with positive and negative DC voltage.

After electrons or positive holes are injected in the oxide film 1b with avalanche injection and they  are trapped at the trap, the current-voltage characteristics are similarly measured. With known relation of equation from the amount of variation of this characteristic, the surface density of the  charge trap center in the insulation film and the spatial distribution toward surface vertical direction for the center of gravity are obtained. Thus, the measurement of trap which is a cause to the  instability of MOST can simply be measured.
