Title: Electric apparatus
Inventor: YOSHIOKA TAKEO
IPC: H02B1/28
Filed: 1981-09-07
Abstract: PURPOSE:To keep the appropriate dried condition of insulating material by detecting  the temperature of the heat-generating part of an electric apparatus and the temperature of a moisture requlating tank placed in a gaseous insulating medium circulation  passage for cooling the apparatus and controlling the moisture requlating tank to keep the difference between these two temperature constant. CONSTITUTION:The coil 2 in a case 1 is cooled by an SF6 gas, e.g., from a cooling  part 3. A blower 5 and a moisture requlating tank 6 are inserted in a duct 7, and  the cooling part 3 is cooled by a cooling fan 4. The temperature of the heat-generating part of an apparatus body is detected by a detector element 8, the temperature of the large amount of the SF6 gas from the cooling part 3 is also detected, and a  cooling fan motor 9 is controlled to make the difference between the two temperatures constant. Upon operating the apparatus the internal temperature begins to rise,  silica gel in the moisture requlating tank 6 absorbs the initial moisture, lowering the relative humidity, which in turn rises the tank temperature to cause water to be supplied. When the temperature falls and thus the relative humidity rises, the silica gel  re-absorbs moisture. This cycle of operation keeps the internal humidity appropriate,  and prevents the discharge due to accumulated charges and the degradation of insulation due to moisture.

Title: Plastic light transmitting fiber and its manufacture
Inventor: YAMAMOTO TAKASHI
IPC: G02B6/00
Filed: 1983-08-02
Abstract: PURPOSE:To obtain a plastic light transmitting fiber superior in heat resistance and durability by forming a core of polycarbonate, a sheath of a transparent polymer specified in refractive index, and a protective layer of a polymer specified in heat deformation temp. CONSTITUTION:A light transmitting fiber is composed of a core 1 made of polycarbonate, a sheath 2 formed of a substantially transparent polymer having a refractive index >=0.01 lower than that of the core 1, and a protective layer 3 made of a polymer having a heat deformation temp. of >=110 deg.C. Light 4 incident at an incident angle theta3 is transmitted repeatedly totally reflected with the interlayer between the core 1 and the sheath 2, and light 5 incident at an incident angle theta4 is also transmitted repeatedly totally reflected with said interlayer, thus preventing noise. Further, light 6 incident from the outside of the protective layer 3 is totally reflected with the interlayer between the layer 3 and the sheath 2 and does not invade into the core 1, because the refractive index of the layer 3 is higher than that of the sheath 2, so no noise is detected. Hence, a plastic light transmitting fiber superior in light transmitting performance and heat resistance can be obtained.

Title: Adhesive sheet transport device
Inventor: TAKATSUKI SHIGEKI
IPC: B65H5/14
Filed: 1979-10-31
Abstract: PURPOSE: To enhance accuracy of stacking of sheets and prevent failure in forming, in an adhesive sheets transport device from the sheet manufacturing process to the press-forming process, by transporting adhesive sheets automatically and locating each of them at the intended place mechanically.  
     CONSTITUTION: Pins 3 are sunk and stuck in an adhesive sheet 5, where they are oscillated in such a way that any pin 3 moves in opposite direction to its adjoining pins, so that tensile stresses are arisen in the adhesive sheet 5 horizontally between the lower tips of every two adjoining pins and the sheet is thus prevented from falling down. When the pins 3 are lifted to carry the adhesive sheet 5 to a stacking place, and there lifted further, the adhesive sheet 5 comes into contact with a scratch plate 1 with its whole surface and falls down on said stacking place. Adhesive sheets 5 can be thus transported automatically.

Filed: 1986-06-18
Abstract: PURPOSE:To shorten a space between toner images and to easily reuse toner by changing the impression of bias voltage to repeat the conversion of a developing part and an erasing part. CONSTITUTION:While moving a dielectric belt 1 in the arrow A direction, an electrostatic latent image is formed on the belt 1 by multistylus electrode 2 and developed by a magnetic brush device 3a. Then residual electrostatic charge on the belt 1 is removed by a destaticizing device 5 and toner is also removed and recovered by a magnetic brush device 3b. In this case 3'a and 3'b indicate respective magnetic brushes. Thereby, toner stored in the device 3a of the developing part is reduced and toner stored in the device 3b, being a erasing part, is increased (process A). The bias voltage is changed when the moved toner reaches a constant volume, and the magnetic brush devices between the erasing part and the developing part are switched. Then the belt 1 is moved in the B direction to recover the developing toner (process B). Thus, the space between the toner images can be shortened and the reuse of toner can be easily executed by repeating the processes A, B.

Filed: 1987-06-05
Abstract: PURPOSE:To allow an even influx of refrigerant to effectively use respective refrigerant passages by orienting the opening of a refrigerant inlet pipe toward the circumferential direction of an annular chamber formed by a header. CONSTITUTION:An inlet header 10 forms an annular chamber 22 connected to refrigerant passages 8 at an end of an outer pipe 9 fitted over an inner pipe 6 in which heating medium passes. Since the opening 24 of a refrigerant inlet pipe 23 is oriented toward the circumferential direction of the annular chamber 22, the refrigerant entering from the opening 24 into the header 10 spirals along the inner surface of the header 10 and the outer surface of the inner pipe 6 without colliding the inner pipe 6. Therefore, the refrigerant can evenly enter independent and separate refrigerant passages 8. In this way, by effectively using the refrigerant passages to enhance the refrigerant capacity, the heat exchanger can be miniaturized, and the manufacturing cost of refrigerating device can be reduced.
