Title: Production of phase difference plate, optical member and liquid crystal display device
Inventor: KONDO SEIJI
IPC: G02F1/13363
Filed: 1999-09-08
Abstract: PROBLEM TO BE SOLVED: To provide a phase difference plate having excellent phase difference accuracy in which the shrinking force of a heat-shrinkable film can be efficiently transmitted to a thermoplastic film to easily control deformation. SOLUTION: In the production method of a phase difference plate, a heat- shrinkable film is adhered to one surface or both surfaces of a thermoplastic film. The heat-shrinkable film satisfies the relation of Tg-90<=Ti, wherein Ti is the temperature at which shrinking based on the initial dimension starts and Tg is the glass transition temperature of the thermoplastic film. Then the thermoplastic film is stretched or shrunk in at least one of the longitudinal or lateral direction by the effect of the shrinking force of the heat-shrinkable film by heat. Then the heat-shrinkable film is peeled. The optical member consists of a laminated body of the phase difference plate and a polarizing plate. The liquid crystal display device is equipment with the phase difference plate, or this plate and a polarizing plate on at least one face of the liquid crystal cell.  Thereby, phase difference due to the double refraction of a liquid crystal cell can be hihgly compensated, and the obtained liquid crystal display device has excellent viewing angle and contrast.

Title: Apparatus for sexing of fish
Inventor: FURUBAYASHI TAKASHI
IPC: A01K61/00
Filed: 1993-10-12
Abstract: PURPOSE:To provide an apparatus designed so as to distinguish between male and female from an image of the caudal fin shape of an objective fish taken by an image pickup unit and capable of quickly and high accurately distinguishing between male and female even in the case the sexual gland region is immature. CONSTITUTION:An analog video signal of an image taken by an image pickup unit is converted to a digital signal by an A/D converter and the resultant digital signal is temporarily stored in a frame memory. After processes, e.g. binarization of the digital image data, labeling, judgment of head or tail, setting of the caudal fin area and judgment of back or stomach, only the caudal fin part is extracted. The aspect ratio of the caudal fin part is calculated by an aspect ratio calculation circuit and the counter line of the caudal fin part is traced by a shoulder picture element calculation circuit to calculate the number of the picture elements going backward from the tracing direction. The ratio L1/L of the distance (L1) to the position giving the maximum value of the longitudinal projection of the caudal fin part to the length (L) of the caudal fin part is calculated by an apex position calculation circuit. If the number of the shoulder picture elements is beyond a prescribed standard value, this apparatus determines it female. If the number is not beyond the standard value whereas the aspect ratio value is beyond a prescribed standard value, this apparatus determines it male. In the case the aspect ratio value is not beyond the standard value, distinguishment is done based on the position of the apex.

Abstract: PURPOSE:To prevent an explosion by catching fire by releasing hydrogen in the air and by supplying N2 gas when the concentration of hydrogen generated in the tank of cooling water circulating in a generator to be cooled by hydrogen and cooling said hydrogen exceeds a specified value. CONSTITUTION:The inside of a stator winding 2 provided in a generator 1 to be cooled by hydrogen gas is made hollow and cooling water is caused to circulate there. Cooling water goes from reservoir 3 via pump 4, cooler 5, feed water pipe 6, inlet header 7, insulating tube 8, stator winding 2, insulating tube 9, outlet header 10 and return pipe 11 and returns to said reservoir 3. The gas pressure of hydrogen is made larger than the water pressure of cooling water to prevent said cooling water from jetting. Hydrogen gas mixed with cooling water in operation is separated in said reservoir 3. The separated gas is sucked up by a pump 15 and the concentration of hydrogen is detected by detector 13 and monitor 14, and when said concentration exceeds a specified value, an automatic switching valve 16 and N2 gas supply valve 19 are switched to release hydrogen gas into an atmospheric escape pipe 12 and to supply N2 gas from tank 21. Thus, it is possible to prevent an explosion by catching fire.

Filed: 1984-12-03
Abstract: PURPOSE: prevent the damages of a disk by stopping a turntable with the aid of information from a discriminating circuit when a difference between rotation al speeds of the turntable and the disk exceeds a set value. CONSTITUTION:An F-V converter 8 outputs a voltage in proportion to the rotational frequency of a motor 4 with the aid of a signal from an optical tachometer 5 during a period from the activation to the stop of the motor 4. Moreover an F-V converter 7 inputs a signal for reading the timing mark for detecting the rotational frequency of an optical disk medium 3 by a phototransistor 6, and outputs a voltage in proportion to the rotational frequency of the optical disk medium 3. The deciding circuit 9 compares the output voltages of the F-V converters 7 and 8. When a difference between the rotational frequencies of the motor 4 and the optical disk medium 3 exceeds the preset value, the deciding circuit 9 outputs an abnormality detecting signal to be transmitted to a motor drive part 10, and stops the motor 4. Thus the damage of the optical disk medium 3 can be prevented.
