Title: Fuel cell
Inventor: WADA MATSUNOBU
IPC: H01M8/04
Filed: 1982-03-27
Abstract: PURPOSE:To improve the performance of electric power generation by providing a pressure regurator in each of air and fuel exhaust systems and controlling it by the output of a differential pressure detection section that detects the differential pressure on both supply and exhaust sides. CONSTITUTION:A manifold 2 that supplies and exhausts air and fuel is mounted on a fuel cell mainframe 1 and is housed in a tank 3 that encloses nitrogen. Gas supply systems 4o, 4h, and 4n and gas exhaust systems 5o, 5h, and 5n with pressure control valves 13o, 13h, and 13n are connected to the manifold 2 and the tank 3. Besides, the control valve 13o is controlled by detecting the differential pressure between the nitrogen input pressure and air inlet pressure by means of a detection section 11a and the control valve 13h is controlled by detecting the differential pressure between the air outlet pressure and fuel inlet pressure. As a result, the gas pressure of fuel and air can effectively be controlled without deteriorating the performance of electric power generation.

The bundle 1 of the reinforced fiber, a net-shaped base cloth 2, and a releasing paper 3 are lapped on and adhered to each other to form a collected fiber sheet S. The adhesive consists of the vinyl monomer to remove the epoxy resin to collect the reinforced fiber, the main component of the epoxy resin, and the hardener, which are kneaded for use. The surface of an object to be reinforced such as concrete is cleaned, the primer is applied thereto, and the adhesive is applied thereto. The collected fiber sheet S is cut, and the adhesive is impregnated therein. These works can be performed on a working table. Then, the sheet is attached to the surface to be reinforced, and ironed on the releasing paper 3 so as to be closely attached thereto. The releasing paper is peeled, and the adhesive is applied for finish.

Title: Microencapsulated toner and production thereof
Inventor: GOSEKI YASUHIDE
IPC: G03G9/08
Filed: 1988-03-04
Abstract: PURPOSE:To attain satisfactory fixability as well as satisfactory durability and shelf stability by adding a water soluble inorg. or org. acid to an org. solvent system contg. a nitrogen-contg. resinous compd. and by removing the solvent to deposit or separate a shell material contg. the resinous compd. CONSTITUTION:A microencapsulated toner is composed of a core material contg. at least binding resin and a colorant and outer walls coating the core material formed by depositing or separating a shell material contg. a nitrogen- contg. resinous compd. from an org. solvent system contg. the shell material and a water soluble inorg. or org. acid. By the interaction between the water soluble acid in the org. solvent and nitrogen-contg. groups in the shell material, the rise of the viscosity of the system due to the deposition of the shell material at the time of encapsulation is inhibited and the aggregation of particles is prevented. Since the water soluble acid is easily removed by removing the solvent at the time of the deposition of the shell material or by post-treatment after microencapsulation, hygroscopic property is not provided to the formed toner and satisfactory fixability as well as satisfactory durability and shelf stability is attained.

Abstract: PURPOSE:To reduce noise attributable to laser energy fed back to the emitting element by a method wherein the intensity of the energy emitted by a semiconductor laser element is detected and the direct current value is regulated according to the intensity of the detected value. CONSTITUTION:A direct current smaller than the threshold current of a semiconductor laser 1 is yielded by a constant output circuit 11.

In this way, fluctuations caused by the feedback of reflected energy may be suppressed. The pulse generator 8 is connected to the semiconductor laser 1 with the intermediary of a capacitor. A light-receiving diode 9 is connected to the driving circuit for the semiconductor laser 1, and to the constant output circuit 11 through the intermediary of a low-pass filter 10. Accordingly, the direct current, supplied by the constant output circuit 11 through a coil to the semiconductor laser 1 on the basis of the signals transmitted by the light-receiving diode 9, is regulated. The regulated direct current is joined by a pulsating current, originating inth pulse generator 8, to drive the semiconductor laser 1 to yield constant-intensity pulses.

Title: Structure of opening in wall
Inventor: HINO MUTSUMI
IPC: F24F7/007
Filed: 1984-03-15
Abstract: PURPOSE:To intercept airflow generated between a curtain and the opening of wall, reduce heat transfer in a room and increase the air-conditioning effect in the room by forming an airflow mitigating screen above the curtain. CONSTITUTION:In winter, warm-air from an air-conditioning machine is discharged slowly from a ventilating port 5 to form the airflow mitigating screen along the whole width of a curtain box 4. According to this method, air in an air gap G1 between a curtain rail 25 and a bent piece 53 is induced by the airflow mitigating screen and flows through the air gap G2 thereby restricting the down flow of cool air due to cold atmosphere, which is generated in the air gap G3 between the opening 2 of wall and the curtain 3, preventing the convection of the cool air and decreasing air-conditioning loss. In summer, the airflow in the air gap G1 is enhanced some times, however, a temperature difference between indoor and outdoor temperatures is comparatively small in case of normal room cooling, therefore, the heat transfer loss is also comparatively small and, consequently, the ventilating port 6 may be utilized as the blow-off port of room cooling from which cool air is discharged.

Abstract: PURPOSE: To obtain the delay time that can be selected of a light beam by using the cell windows each consisting of an optically transparent semi-insulating crystalline material sheet which is annealed after ion implantation and has uniform transmissivity characteristics with respect to radiation energy of prescribed wavelengths. CONSTITUTION: Each of electrooptic cells 40 used as polarization plane rotators 12 and 14 respectively has electrically conductive layers 44, antireflection layers 46 and 47 and cell windows 42. Liquid crystal molecules 50 in each of the cells 40 are rodlike organic molecules.

In the first state of a control signal 26 for rotating the direction of polarization plane of polarized light passing through the rotators 12 and 14, the light given to a time delay device 10 travels a first optical path passing through the rotator 12, Brewster plates 16 and 18 and the rotator 14. In the second state of the control signal 26, the light is reflected by the Brewster plate 16, mirrors 20 and 22 and the Brewster plate 18.  At this time, the delay time is equivalent to the difference between the total length of optical paths 28a, 28b and 28c and the length of an optical path 29. Thus, delay time that can be selected of a light beam can be provided to between a light source and its utilization means.
