Title: Current supply method for ac operated railway
Inventor: NOUKI SADAJI
IPC: B60M3/04
Filed: 1981-04-17
Abstract: PURPOSE:To enhance reliability for operation of an electric car by feeding the current in such an arrangement that there is not any momentary interruption of power supply to the electric car just when the car passes any dead section existing between parallelly installed two power sources and that the car can pass over from one to the other source in the condition of power drive. CONSTITUTION:Between railway lines 3a and 3c connected to No.1 and 2 substations 1a and 1b, respectively, an electric car 3b is interposed with No.1 and 2 dead sections S1, S2, and No.1 and 2 circuit breakers 5a, 5b are installed between this line 3b and the lines 3a, 3c. Reactors 7a, 7b for restriction of transverse current are installed through No.3 circuit breaker 5c and a balance reactor 6. The line 3b is supplied with current from the substation 1a through circuit breaker 5a until the electric car T passes the dead section S1, and the circuit breaker 5a is disconnected during current supply to the line 3b after the breaker 5c is put on. Thus current supply is made from both substations 1a, 1b.

Title: Overcurrent protecting circuit for dc stabilized power supply circuit
Inventor: KAWAGUCHI TSUKASA
IPC: G05F1/56
Filed: 1986-03-18
Abstract: PURPOSE:To reduce the rating level and the cost of parts of a DC stabilized power supply circuit by using a switching element which is turned off when the load is short-circuited together with reduction of the output voltage level. CONSTITUTION:When an output terminal B of a voltage regulator 3 is short- circuited, the potential of the terminal B is set at the same level of that of the cathode of a light emitting diode D of a photocoupler 7. Thus the diode D is turned off and therefore a phototransistor PT is also turned off. Then the conduction is broken between a common terminal C of the regulator 3 and an earth E. Thus the regulator 3 loses its control input and is turned off and therefore the output of the regulator 3 is equal to zero. Here a Zener diode 5 is turned on again owing to the difference of potential between an input terminal A and the terminal B of the regulator 3. Thus a current flows from a non-stabilized DC power supply 1. However the short circuit current can be reduced by setting previously the value of a resistance 4 at a high level.

Abstract: PURPOSE: To obtain the titled fine particles for clinical tests having a good measuring sensitivity, by polymerizing acrylonitrile or methacrylonitrile into the form of fine particles, hydrolyzing the fine particles, and reacting an immunological active substance with the resultant specific carrier particles.  
     CONSTITUTION: Acrylonitrile or methacrylonitrile is polymerized in a medium, e.g. ethyl propionate, which will dissolve the monomer mixture but precipitate and deposit the resultant polymer in the presence of a crosslinkable monomer, e.g. divinylbenzene, having at least two polymerizable carbon-carbon double bonds to precipitate and deposit a fine particulate polymer having an average diameter of 0.03W10μm. The resultant fine particulate polymer is then hydrolyzed and reacted with an immunologically active substance, e.g. syphilitic treponemal antigen or HBs antigen, to give immunologically active fine particles. The resultant carrier consists of polyacrylamide particles having a uniform particle size, and has very little nonspecific adsorption, e.g. protein, and facilitates the measurement.

Title: Driving system of magnetic bubble
Inventor: SHIRASAKI MASATAKA
IPC: G11C11/14
Filed: 1982-04-09
Abstract: PURPOSE:To obtain a driving system capable of moving individual magnetic bubbles optionally, by irradiating a conductor layer adhered to the surface of a magnetic material substrate selectively with circular polarized light and moving the irradiated area. CONSTITUTION:In a figure, when the surface of an Al film 2 is irradiated with the circular polarized light (rotary polarization) 4 having about 10mum wavelength, a revolving current flows through the Al film by its revolving magnetic field to produce a magnetic field at right angles to the film. When this vertical magnetic field is in the same direction with that of a magnetic bubble, the magnetic bubble is attracted to the circular-polarized-light irradiated area and as a sweep to said irradiated area is made, the magnetic bubble also moves following up it. Therefore, a desired magnetic bubble is transferred to a desired position by irradiating the position where the magnetic bubble is present with said circular polarized light and then moving the irradiated area to the desired position by an optical or mechanical means.

Filed: 1984-03-29
Abstract: PURPOSE:To prevent the occurrence of galling between each of members during operation, by constituting a transmission gear, transmitting the operation of an actuator to a pilot valve, with a flexible member. CONSTITUTION:When a drum 19b is rotated in an arrow direction by an actuator, a wire 18 is hoisted up, whereby a pilot valve 14 goes up against a spring 16, and a valve plate 14a comes off a valve seat 12e at the upper end of a cylindrical part 12d at the inner side. If so, the fluid that flowed in a hydraulic chamber 6 from a fluid inflow port 11a by way of a passage 11d flows out to a fluid outflow port 11b from the valve seat 12e. Accordingly, pressure in the hydraulic chamber 6 drops to some extent, while a main valve member 12 goes up against a spring 15, and the fluid flows in the outflow port 11b from the inflow port 11a. With this constitution, a possibility of any galling among all members during operation may no longer happen there.

IPC: G02B5/20
Filed: 1992-02-13
Abstract: PURPOSE:To provide a display device which prevents color reduction and color mixture at each filter boundary part at a permissible visual field angle when a primary-color filter for improving contrast is used. CONSTITUTION:The color filter 5A consists of red, green, and blue filter parts 5R', 5G', and 5B' formed in partitioned areas so that mutually adjacent parts of the filter parts increase in transmissivity in order toward the sections 15 and 16. The unit element 1A of the display device has an electron tube part 2, a phosphor 3 consisting of fluorescent parts 3R, 3G, and 3B, and a glass plane 7 where the color filter 5A is formed. The color filter 5A prevents the light from the fluorescent parts 3R, 3G, and 3G from being reflected to improve the contrast. The transmitivity of the adjacent boundaries of the filter parts 5R', 5G', and 5B' are increased, so, even if, red fluorescent light beams R1-R3 from the fluorescent part 3R are made incident on the peripheral edges 17-15 of the filter part 5B', neither color mixture with blue nor color reduction is caused.
