IPC: F21V9/16
Filed: 1989-05-31
Abstract: PURPOSE:To improve the brightness of a display surface by providing a lenticular lens-shaped substrate which is made of transparent material containing phosphor and whose one main surface, at least, is constituted of plural adjacent cylindrical convexes. CONSTITUTION:The fluorescent screen 10 is formed by extruding and molding synthetic resin material containing the phosphor which is obtained by mixing and dispersing the phosphor in the transparent synthetic resin material by the use of a lenticular lens-shaped forming mold, for example, a forming mold where cylindrical lens group are juxtaposed in parallel with each other on both main surfaces. The lenticular lens itself is a transparent plate consisting of semi-circular lens group on at least one main surface and has such a shape that the respective surface areas of the cylindrical lens group are juxtaposed adjacently and in parallel with each other. Thus, outgoing light is condensed by the surface of each cylindrical lens and the brightness of the screen 10 is improved.

Title: Bulk material carrying vessel
Inventor: IIO MIKIO
IPC: B63B27/22
Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To prevent sinking of a vessel due to flooding up to the whole of the vessel when a hull is damaged by stranding and collision by forming each discharging machine passing port passable by discharging machines on bulkheads forming cargo compartments by partitioning a hold and providing each elevating/lowering watertight door at each discharging machine passing port. SOLUTION: By closing discharging machine passing ports 721, 731 formed on bulkheads 72, 73 by a sinking preventing device constituted of watertight doors provided at through portions 75, 76, 77 of a discharging conveyor 8 at vessel bottom parts of bulkheads 71, 72, 73, 74 during a voyage and lowering each watertight door, each cargo compartment 21, 22, 23 forms a watertight state independent each other. As a result, when the vessel is damaged in the hull by stranding and collision during the voyage, the whole of the vessel does not sink due to flooding of the whole of the vessel.  Because the vessel is allowable only if it is provided with a common wheel type discharging machine traveling by passing through each cargo compartment, equipment cost is not increased, and an adjustment of discharging amount at the time of loading and an adjustment of balance of the vessel can be extremely easily performed.

Title: Proportional flow adjusting meter
Inventor: NAKAO MASAHARU
IPC: F16K31/12
Filed: 1980-10-03
Abstract: PURPOSE: To attain a fuel supply properly proportional to an air supply a balance of forces in an adjusting meter provided for a fuel supply device for use in a combustor or the like by disposing in a fuel passage a throttle which can change an area its opening in order to control a poppet to automatically open or close by the throttle.  
     CONSTITUTION: If an air blower 2 and a fuel pump 6 are started, air is throttled by an air throttle 11 and is fed into a combustion furnace 1 with a flow amount thereof controlled by a regulator valve 10. In the meantime, a float 16 moves downwardly by a difference of pressure appearing on opposite sides of the throttle 11 to push down a poppet 53 so that fuel is fed into a chamber A4 along a passage 51 and then passes a communicating hole 30, a throttle 25, a chamber A3, and a supply passage 5 and is injected from a fuel injection port 9. If the regulator valve 10 is controlled to open or close in response to the temperature of the combustion furnace 1, the air blow amount is adjusted while the poppet 53 is moved correspondingly by up and down movement of the float 16 to thus adjust the amount of fuel supply. If the fuel supply amount changes, pressure P1, P2 on the opposite sides of the throttle 25 changes correspondingly to move the poppet 53 upwardly or downwardly. Thus, the fuel supply amount is controlled at a position where a balance with the difference of pressure (P1-P2) is reached.

Filed: 1982-08-12
Abstract: PURPOSE:To manufacture a coupler with high mass productivity and high reproducibility by utilizing a fiber which is beforehand united with two cores and utilizing a base material of a prescribed size in the stage of fabrication. CONSTITUTION:Two pieces of base materials for an optical fiber which are beforehand fabricated to a semi-circular cylindrical shape are combined to position the polished surfaces thereof to oppose to each other, and the combined materials are drawn. The core diameter of the drawn optical fiber 10 is made to have the size that provides a single operation mode at the difference in the specific refractive index between the cores 11 and the clad and the using wavelength. When the fiber is drawn, the individual optical fibers of the semi-circular cylindrical shape are single mode optical fibers. If part 12 of the fiber 10 drawn as a whole is stretched with heating to a desired diameter, the normalization frequency V of the stretched part 12 changes with the degree of the stretching. The light propagating in the optical fiber spreads to the clad part owing to the V value of the optical fiber so that optical coupling is generated between the respective cores.

Title: Tester for dc dielectric strength
Inventor: EBINUMA YASUMITSU
IPC: H01B13/00
Filed: 1982-08-10
Abstract: PURPOSE:To discharge the electric charge of a test cable in an early time with a discharge means which prevents the generation of spark discharge, by providing the charge discharge means consisting of a trigger signal generator which switches respectively successively switching element groups. CONSTITUTION:When no electric current is flowed to the gate of an SCR1, the SCR1 is off but when light is transmitted from a gate signal generator 3 through an optical fiber 2 to a protodiode r1, electric current begins to flow to the photodiode r1 which is applied with the light at its p-n junction face, resulting in a decrease in a resistance value. Then the potential difference at both terminals of a resistor R0 is applied between the gate and cathode of the SCR1 and the SCR1 is made conducting. Since this conduction is equivalent to the short circuiting of resistors R0+R1, the electric charge accumulated in a test cable 4 is discharged from the ground side of the cable 4 to the negative side of the cable 4 by passing the resistances R0+Rn, R0+Rn-1-R0+R2, SCR1. It is possible to attain the discharge form of SCR2, SCR3-SCRn as well by making the same successively conducting by the similar procedure.
