Abstract: PURPOSE:To uniform the sealing interval of liquid crystals by spraying spacer particles charged with negative electricity, scattering the srayed spacer particles with electric resiliency and dispersedly arranging the spacer particles on the surface of a substrate. CONSTITUTION:At the time of spraying SiO2 beads 2 with 1.5mm average particle size from a nozzle 3, -100kV static electricity is generated from an electrode 4 to charge the beads 2 with negative electricity and the negative beads 2 are scattered by electric resiliency and dispersely arranged on the surface of the substrate 6. The substrate 6 has a transparent electrode film and an oriented polyimide film on its surface and epoxy resin adhesive is printed out on its peripheral part. The SiO2 beads 2 are dispersely arranged on the substrate 6 with about 300 particles/mm<2> density. The processed substrate is superposed to the other substrate, and both substrates are heated and pressed and then liquid crystal having a laminating chiral smetic C phase is sealed between substrates to obtain the ferroelectric liquid crystal display device with 1.5mum inter-substrate interval.

Title: Paper detecting device
Inventor: YAMAMOTO HAJIME
IPC: B65H26/08
Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To accurately detect the residual quantity of roll paper. SOLUTION: This device is provided with a hopper 5, which stores roll paper S in a rollable manner being drawn out toward a printing part 1, a movable actuator 11, which is installed in a side surface of the hopper 5 and is energized so that it displaces itself toward the inside of the hopper 5 when the roll diameter of the roll paper S becomes smaller than a prescribed value, and a detector 12, which switches its output, based on the action of the displacement of the actuator 11. In this way, the actuator 11 greatly moves toward the inside of the hopper 5 when the roll diameter of the roll paper becomes smaller than the prescribed value, and the large movement of the actuator 11 is surely detected by the detector 12. After this detection, the actuator 11 is kept as it moved within the hopper 5, thereby stabilizing the output from the detector 12.  With this, the residual quantity of the roll paper can be accurately detected.

Title: Air conditioner
Inventor: TAKASHIMA TOSHIO
IPC: F24F1/00
Filed: 1989-11-20
Abstract: PURPOSE:To enable ensurance of heating capacity to a value higher than a specified value by a method wherein a radiator having a hot water pipe and a cooler having a refrigerant pipe are separated away from each other, and the size of the hot water pipe is increased to a value higher than that of the refrigerant pipe to suppress a pressure loss of hot water in the hot water pipe to a low value. CONSTITUTION:Since, during both cooling and heating operation, a cooler 12 is completed separated away from a heater 13, a fear of the heat of the cooler 12 (heater 13) being transferred to the heater 13 (cooler 12) is reduced to prevent reduction of heating and dehumidifying capacity. Further, since the size of a hot water pipe 15 of the heater 13 is increased to a value higher than that of a refrigerant pipe 14 of the cooler 12, the pressure loss of the hot water pipe 15 and reduction of an amount of circulating hot water are decreased to prevent lowering of heating capacity. In other words, since the size of the refrigerant pipe 14 is smaller than that of the hot water pipe 15, piping of the refrigerant pipe 14 is drawn around comparatively freely (in comparison with the hot water pipe) to improve cooling capacity.

Abstract: PROBLEM TO BE SOLVED: To suppress a temp. change of a magneto-resistance effect type head by preliminarily heating the head with a preliminary heating current of a current value smaller than a sense current value at the reading time for detecting a leakage magnetic field from a magnetic recording medium at the idling time. SOLUTION: A rated sense current is supplied from a constant voltage source 6 to an MR element (magneto-resistance effect element) 3 in synchronization with the operating time of a demodulation circuit 8 by a control circuit 7, and also the preliminary heating current of the smaller current value than the rated sense current value is supplied from an AC power source 5 to the MR element 3 in synchronization with the nonoperating time of the demodulation circuit 8. Then, at the idling time, the preliminary heating current as, for instance, 80% of the rated sense current value for detecting the leakage magnetic field from the magnetic recording medium is made to flow into the MR head to be preliminarily heated up. Consequently, at the time of shifting from the idling time to the data reading time, and at the time of shifting from the data reading time to the idling time, the temp. change of the MR head can be suppressed.

Abstract: PURPOSE: To prevent excess wetting of a supply electrode, and prevent drop in output of a fuel cell by supplying water in a good state of steam. CONSTITUTION: A hydrogen gas humidifier 110 is constituted with a porous film 111, and separators 113, 115 which interpose the porous 111 from both sides and form a hydrogen gas flow path 113p and a water flow path 115p respectively. The porous film 111 is a polyolefin porous film and has hydrophilic nature. In the hydrogen gas humidifier 110, water in the water flow path 115p permeates the porous film 111 according to the difference between the pressure of water flowing in the water flow path 115p and the pressure of hydrogen gas flowing in the hydrogen gas flow path 113p. Since the porous film 111 has hydrophilic nature, permeated water comes in contact with the porous film 111 in a wide contact area. Water is easily vaporized by receiving heat from both the porous film 111 and the hydrogen gas, humidification is conducted in a good state of steam.
