Abstract: PURPOSE:To provide the adaptability for packing machine as well as the label adhesion by composing a packing film of the oriented film of a mixture, which contains a specified amount of nonionic surface active agent and of which both surfaces or the entire contains ethylene-vinyl acetate and high-density polyethylene at a specified ratio. CONSTITUTION:For single-layer film, it is necessary that the entire film is composed of an oriented body consisting of 95.0-99.7wt.% of ethylene-vinyl acetate copolymer and 5.0-0.3wt.% of high-density polyethylene, and for multi- layer film, the layer composing its both surfaces may be the oriented body of the composition containing said copolymer and said polyethylene at said ratio. If the content of high-density polyethylene in the composition is in the range of 0.3-5.0wt.%, the balance of lubricating property and adhesion is favorable and an excellent adaptability for packing machine is obtained. It is necessary that 0.3-5.0wt.% of nonionic surface active agent is contained in the composition in the ratio to the total amount. Then, the lubricating property and the adhesion are improved to be well-balanced without deterioration of label adhesion, by combining the composition of both surfaces and the effect of orientation.

Title: Heat detection method using optical device
Inventor: TAGO MAKOTO
IPC: G01K11/12
Filed: 1990-11-26
Abstract: PURPOSE:To detect the generation of heat with high sensitivity by transmitting polarized light to an optical fiber and detecting the change of light output accompanied by the rotation of the plane of polarization of light caused by the bending of the optical fiber due to the thermal deformation on the shape memory alloy arranged in the vicinity of the optical fiber. CONSTITUTION:The polarized light emitted from an LED is transmitted using an optical fiber 1 such as a single mode fiber and the plane of polarization of the polarized light in the optical fiber 1 is certainly kept. A heat detecting shape memory alloy 2 is arranged in the vicinity of the optical fiber 1. When the shape memory alloy 2 is deformed by a fire or other heat, bending is generated in the optical fiber 1 and the plane of polarization of the polarized light is rotated. Light output is detected by a photodetector PD through an analyser 3 and the output fluctuation due to the rotation of the plane of polarization is detected to detect the generation of heat. Since the plane of polarization is rotated even by slight bending, the life of the optical fiber 1 is extended and detection sensitivity also becomes high.

Title: Image pickup device
Inventor: YOSHIDA JUNICHI
IPC: H04N5/335
Filed: 1987-12-17
Abstract: PURPOSE:To reproduce a natural picture without white fuzziness even from an object with a wide contrast by varying the exposure of an image pickup element by one frame or one field, reading an image pickup signal and adding both the signals syuchronizingly. CONSTITUTION:Since the signal charge stored in the 2nd frame during periods C1, D1 is swept away by a sweepout pulse inputted from a synchronizing signal generating circuit 5, the undesired signal charge stored during the periods is read by a vertical CCD, and transferred at a high speed at a sweepout part. Thus, since the image pickup signal read from the CCD 3 by the 2nd frame has a signal charge storage time is C2 and D2 period, the time is shorter than the case with that of the 1st frame. Moreover, the 1st frame delay means 7 retards the image pickup signal of the 1st frame by one frame and made synchronous with the video signal of the 2nd frame and an adder means 8 adds both the signals. Thus, the pickup signal is mainly the major component of the input picture and the image pickup signal without white fuzziness is obtained even at a high brightness part.

IPC: G01J1/42
Filed: 1990-11-28
Abstract: PURPOSE:To obtain a circuit where a light sensor can be commonly shared over a wide working illuminance range by providing a switch unit with a reference voltage generating unit connected to an amplifying feedback resistor in parallel to form a closed circuit. CONSTITUTION:When a light sensor 2 is subjected to light application, it generates short-circuit current of photocurrent Ish. Without a reference voltage generating unit 4 and an ideal diode 5, an inverted terminal of an operational amplifier 1 is equivalently 0 V so that its output voltage will be Vout = Ish x (Rf1 + Rf2). If the generating unit 4 and the diode 5 are added to both ends of an amplifying feedback resistor 3-1, the generating unit 4 functions as a differential amplifier circuit so that V0 = Vout - Vreff appears at its output V0. When input voltages at a non-inverted terminal and at an inverted terminal of the opperational amplifier 15 are assumed to be V+,V-, resistances 14,17,18 are all equal to one another, so that V+ = 1/2Vout and V- = (Vreff + V0)/2 wherein V+ = V- is satisfied according to conditions of virtual short-circuit and V0 can be easily obtained.
