Title: Fiber array for measuring reflected light
Inventor: HATSUTORI YASUJI
IPC: G01B11/00
Filed: 1984-03-24
Abstract: PURPOSE:To accurately detect the unevenness of an object by performing uniform illumination by light transmission fibers without superposing the light receiving regions of light receiving fibers, by making the opening angle 2theta1 of each light transmitting fiber larger than the opening angle 2theta2 of each light receiving fiber. CONSTITUTION:Light transmitting fiber 11, 12... each having an opening angle 2theta1 and light receiving fiber 21, 22... each having an opening angle 2theta2 are parallelly arranged in a unidimensional or two-dimensional pattern at intervals D for obtaining predetermined resolving power and constituted so as to satisfy relation of theta1>theta2 between said opening angles 2theta1, 2theta2. Therefore, illumination regions S1, S2... shown by the solid line are superposed, in such a range that the distance L between the leading end of the fiber array and an object is LM and LP, to impart uniform illumination whereas light receiving regions R1, R2... shown by the dotted line are not superposed and the information of a distance based on the unevenness of the object can be detected accurately.

Title: Electrophotographic cadmium sulfide particles
Inventor: SUZUKI KIYOSHI
IPC: G03G5/08
Filed: 1981-04-15
Abstract: PURPOSE:To prevent fine roughness on a coated surface, by dispersing electrophotographic cadmium sulfide particles having 0.1-0.5mum average particle diameter and no agglomeration among them into a binder resin and coating them on a substrate. CONSTITUTION:Cadmium sulfide particles free from agglomeration among each particle and having 0.1-0.5mum average particle diameter are produced by reacting cadmium ions reduced in concentration with hydrogen sulfide, then further adding cadmium ions to conduct reaction, while keeping the cadmium ion concentration always low, and repeating such operations for reacting these ions in several times. Impurities called an acceptor or a donor, when needed, are contained in the cadmium particles. It is necessary to control an amount of acceptor in accordance with its particle diameter, and as the diameter becomes larger, it is desirable to add a larger amount of acceptor.

Title: Water making equipment
Inventor: SAMEJIMA TSUTOMU
IPC: E03B3/28
Filed: 1979-05-07
Abstract: PURPOSE: To provide a larger volume to adsorbent layer container in adsorption process and a smaller volume in desorption process by installing movable walls in a container tower in an equipment to produce water from moisture in gas using adsorbent.  
     CONSTITUTION: In adsorption process, movable walls 1c, 1d are made to contact the inner wall surface of a container tower 1, so that the adsorbent layer container section 1e is provided with a large volume and therefore is effective in sucking sufficient amount of air and in adsorbing large amount of moisture by adsorbent layers 1a, 1b. In desorption process, the movable walls 1c, 1d, are moved horizontally to provide smaller volume and surface area to the adsorbent container section 1e. This also makes rooms 1f not containing adsorbent, between the adsorbent section 1e and the inner walls of the container tower 1. This results in reduced heat dissipation discharged from the adsorbent section 1e and reduced requirement for calory to raise the temperature of the section 1e to a desired value.

Title: Optical recording medium
Inventor: MATSUO YOSHIHIRO
IPC: G11B7/245
Filed: 1985-03-20
Abstract: PURPOSE:To improve the stability and reliability by using a composite body consisting of a compound having a photochromic functional group and a cross- linked polymer having a network structure in which the size of the meshes is nearly equal to or several times the size of the photochromic functional group. CONSTITUTION:The space where photochromic functional groups present in the meshes of a cross-linked polymer can freely move in an ordinary state is limited by restricting the size of the meshes or forming a proper side chain having a smaller size than the meshes. A reversible change between a light energy state and a low energy state is controlled by a steric hindrance effect. When writing or erasure is carried out with said composite body, it is necessary to cause a photochromic reversible change by heating the composite body to a temp. above the softening point. The chain of the cross-linked polymer is softened by the heating, so the steric hindrance effect is eliminated. The low energy state can be changed into the high energy state by irradiating light having the required specified wavelengths while supplying heat energy.

Title: Rotor for magnetic coupling
Inventor: POORU EI RAASUN
IPC: F16D27/14
Filed: 1994-03-03
Abstract: PURPOSE: To prevent a rotor from being damaged too earlier while high torque capacity of an electromagnetic clutch is kept by strengthening a bridge part between slots of a disc of a rotor of an electromagnetic clutch. CONSTITUTION: Two circumferentially extending and radially spaced rows of circumferentially spaced slots 54 are provided in a disc 40 provided in a rotor 35 of a six-pole electromagnetic clutch. Short circumferentially extending bridges are provided between the slots adjacent to each other in each row. To strengthen the bridges against failure under high load and heavy wear conditions, a stainless steel reinforcing ring 58 is brazed to the outer pole ring 41 and the disc 40 and transmits torque between the two. The outer edge of the disc 40 is thus spaced radially inwardly from the outer pole ring to establish an annular air gap which coacts with the two rows of slots to enable the rotor to possess the requisite magnetic characteristics to function in a six-pole electromagnetic clutch.

Title: Fuel assembly
Inventor: HIRUKAWA ATSUJI
IPC: G21C3/334
Filed: 1991-03-20
Abstract: PURPOSE:To make it possible to change sharply an average void rate in a core while suppressing an increase in the number of water rods, by providing a square-tube-shaped channel box with coolant channels of which two adjacent sides have double structures. CONSTITUTION:In L-shaped coolant channels 27 and 28 of two sides on the opposite side (N-N side) to fuel rods 11 of a fuel assembly 10 constituting a core, voids are generated at the time of an output operation of a reactor (BWR) and adsorption of neutrons is little. At the time of stoppage, cooling water is filled up, the N-N side is put in an overmoderated state and the water acts as an absorber, lowering a neutron multiplication factor of the fuel assembly 10 to a large extent. At the time of the output operation, besides, steam is filled up in the channels between L-shaped double walls of a channel box 17 when the flow rate of coolants 27 and 28 passing through the core lowers, and the quantity of the steam in the channels 27 and 28 between the L-shaped double walls lessens remarkably when the flow rate of the coolant increases. Accordingly, reactivity in the last period of an operation cycle can be increased.

Abstract: PURPOSE:To remove an electric load generated in diode groups connected to a non-selective line without flowing out to a circumference by constantly flowing out the electric charge generated in a photoelectric conversion diode except the time to read out to an outside. CONSTITUTION:Two diode switches DSnn1 and DSnn2 are respectively arranged to one photoelectric conversion diode Dnn. When the first line of a scanning line 3 is selected and the scanning line 3 of a second line and onward is non- selective, DS111, DS121, DS212 and DS222 are conducted and DS112, DS122, DS211 and DS221 are made into non-conductive condition.

Thus, the photoelectric charge can be flowed out to an outside regardless of the selective time or the non-selective time, a photoelectric charge generated in the non-selective time is not accumulated, an excess electric charge spreads out to a circumference and a blooming is not caused.
