Title: Production of thermoplastic resin foam
Inventor: NAKAO TAKU
IPC: C08J9/12
Filed: 1992-09-29
Abstract: PURPOSE:To procude a resin forma having a complicated shape, an excellent surface appearance and a high expansion ratio by infiltrating a physical blowing agent into a specified thermoplastic resin molding and foaming the molding by heating. CONSTITUTION:A physical blowing agent is infiltrated into a thermoplastic resin molding having a practical height at least five times as large as the thickness of the surface part of the molding, and the molding is foamed by heating to a temperature equal to or higher than the glass transition temperature of the thermoplastic resin to produce a thermo-plastic resin foam having a wall thickness of the surface part of 2mm or above and a density of 0.04 g/cm<3> or below. The above foam needs to have good strengths and surface appearance. In order to obtain a foam having fine and uniform cells, for example, a combination of a polycarbonate resin with carbon dioxide is particularly desirable, for a uniform fine cell foam having a high expansion ratio can be obtained by impregnating a polycarbonate resin with carbon dioxide, and heating the resin with steam.

Title: Lighting equipment
Inventor: KYODA MASAHIKO
IPC: F21V23/02
Filed: 1988-10-15
Abstract: PURPOSE:To achieve high efficiency heat radiation from exothermic parts by depositing a heat radiation plate composed of a plate material of a large heat conductivity such as aluminium on an outer surface of an equipment body of a part to which the exothermic parts are attached, with which it is fixed thereupon. CONSTITUTION:An equipment body 1 is formed in a rectangular parallelopiped with an opening in the bottom by a plate material of relatively small heat conductivity such as an iron plate. Inside of the equipment body 1, a lamp 2, a stabilizer 3, an emergency lamp block 4, a battery 5 are arranged, as well as a reflecting plate 6 on the upper side of the lamp 2. On the part corresponding to exothermic parts such as the stabilizer 3 and the battery 5, a heat radiation plate 7 is deposited on an outer surface of the equipment body 1 to be fixed thereupon along with the exothermic parts. The heat transmitted to the heat radiation plate 7 is expanded to heat radiate in the entire plate due to the interior heat conduction thereof. Effective heat emission to the outside of the equipment body 1 can thus be executed.

Title: Electron gun for image receiving tube
Inventor: SHIRAI MASAJI
IPC: H01J29/48
Filed: 1989-10-06
Abstract: PURPOSE:To enlarge the bore of electrode and reduce aberration of a main lens by maximizing the outside dia. of a pair of electrodes constituting a rear stage lens as a major part to generate the aberration of the main lens. CONSTITUTION:An electron gun concerned is composed of two lenses-i.e., a front stage unipotential (UPF) lens and a rear stage bipotential (BPF) lens. Among them the rear stage BPF is a one which has a major roll to reduce aberration of a main lens due to enlargement of the bore. This evolves to enlargement of only the cup outer wall outside dia. max. amount W2C of electrode and the flange outside dia. max. value W2F of electrodes 6-4 in the part mating with G6 electrode 7 among G5 electrode group and G6 electrode 7 forming the rear main lens, while the cup outer wall max. value W1C of electrode and the flange outside dia. max. value W1F of electrodes 2 through 6-3 belonging to other main lens are reduced. This enhances the anti-voltage characteristics of the whole electron gun without sinking the aberration characteristic of the main lens.

Abstract: PROBLEM TO BE SOLVED: To provide a liquefied-gas evaporation apparatus which uses sea water or the like as a heat source, can efficiently recover cold heat, and can stably evaporate a liquefied gas even when the cold heat load varies. SOLUTION: In an LNG evaporation apparatus 11, an intermediate medium liquid 18 is evaporated with a chloro fluorocarbon evaporator 14 by using sea water, river water or the like as a heat source; and LNG flowing through a heat transfer pipe 15 in an LNG evaporator 12 is heated and evaporated with the resultant intermediate medium vapor 19. The evaporated NG is subjected to heat exchange with sea water in an NG heater 13 to be heated to normal temperature. The intermediate medium liquid 18 cooled by the evaporation of the intermediate medium in the fluorocarbon evaporator 14 is supplied to a cold-water-production heat exchanger 20 to cool cooling water. Thus cooled cooling water cools, in an absorbed air cooler 35, air sucked by an air compressor 34, thus enabling the output and efficiency of power generation of a gas turbine generator to be improved.

IPC: G02B13/00
Filed: 1996-09-11
Abstract: PROBLEM TO BE SOLVED: To obtain a combined lens which is excellent in workability, is used under a light source of white or multiple wavelengths and is well corrected of various aberrations and more particularly chromatic aberrations by arranging a radial type distributed refractive index lens which has an approximately flat planar shape on both surfaces and is smaller in the Abbe number on the periphery than the Abbe number on the axis and a homogeneous lens in proximity. SOLUTION: A homogeneous lens Lh which has a flat planar shape on the surface on at least one side and the radial type distributed index lens G which has a refractive index gradient in a radial direction from the optical axis and has the flat planar shape on both surfaces are arranged in proximity. The Abbe number in the peripheral part of the radial type distributed index lens G is made smaller than the Abbe number on the optical axis. The prevention of the eccentricity between the axis of the surface and the axis of a medium which is of a problem at the time of actual working is made possible by forming both surfaces of the radial type distributed index lens G to the flat planes. Further, the combined lens having sufficient refracting power is obtainable without increasing the thickness of the radial type distributed index lens G if the homogeneous lens Lh is arranged in proximity.

Abstract: PURPOSE:To improve the laser oscillation responsiveness of a gas laser device while an abrupt current is prevented from flowing to a power-supply board for supplying discharging power to electrodes. CONSTITUTION:Upon receiving a CW operation (continuous operation) command, a controller 31 outputs a main discharge command to a pulse generator 32 successively to a preliminary discharge command.

Filed: 1988-10-19
Abstract: PURPOSE:To reduce flicker caused on the screen by using a scanning line data not thinned out so as to scan for a period corresponding to the thinned scanning line data with time expansion thereby reducing the pause period of the scanning line. CONSTITUTION:A video signal (Y/C) outputted from a television receiver 1 is written alternately in line memories 2, 3. In the case of interleaving the scanning line to 1/n, one of each n scanning line data coming from the receiver 1 is written in the memory 2. The scanning line data of n-preceding written already in the memory 3 is read at a speed being 1/n of the write speed. Then the unthinned scanning line data is used for scanning with time expansion to display one scanning line. The switches 5, 6 are thrown in opposite to attain alternate use of the memories 2, 3 and display. The speed of the scanning line data unthinned is decreased to 1/n of the substantial speed during the thinned scanning line period and there is not difference in the current consumption between the interleaved period and the unthinned period and the production of flicker is reduced.
