Abstract: PURPOSE: To provide a method capable of planing how to extend a service life of an in-lining material in consideration of the service life of a repapered material accompanied by the generation of cracks on an in-lining refractory wall of an induction furnace. CONSTITUTION: In a lining refractory for an induction furnace, a working layer 2 is formed with a hardened sintering layer produced by the heat received from molten steel where it is specified as a monolithic refractory provided with high corrosion resistance while a non-working layer 5 is formed with a monolithic refractory which is not hardened in the heat treatment up to 1000 deg.C.

Title: Concentration cell type carbon dioxide gas sensor
Inventor: MIZUSAKI JUNICHIRO
IPC: G01N27/406
Filed: 1993-02-12
Abstract: PURPOSE:To allow manufacture of a downsized, steam resistant low temperature operation gas sensor by employing lithium carbonate mixed with alumina as a solid electrolytic material for composing the cell of a sensor. CONSTITUTION:A solid electrolyte 1 mixed with Al2O3, is employed as a substance containing an alkaline carbonate as a matrix. Since lithium carbonate has high affinity with water, it can exist stably upto the vicinity of melting point even when steam is present. Furthermore, the sensor can be operated at low temperature by adding Al2O3 and metal ions of carbonate having valency different from that of Li to lithium carbonate. Porous Au paste electrodes 2, 2' are formed on the opposite sides of the electrolyte 1 and then connected with current collectors 3, 3' of Au mesh and Au lead wires 4, 4' thus constituting a cell. The cell is loaded to an Al2O3 pipe 5 and subjected to gas seal 6, 6'. Reference gas is then fed into the pipe 5 whereas a gas to be sensed is fed to the outside thus constituting a concentration cell. Concentration of CO2 is measured based on the difference of electromotive force between both electrodes.

IPC: G03B9/10
Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To reduce the small amount of exposure irregularity occurring around the peripheral part of a photographic picture frame on a photographic film. SOLUTION: A shutter mechanism executing one exposure of the photographic film by rejecting one shutter blade 60 and reciprocatingly fluctuating it once is adopted for a film unit with a lens. The blade 60 is provided with a circular- arc plate 60c on a rotation locus with a rotary shaft 60b as a center and a slit aperture 60e is formed at one part of the plate 60c. Then, when the blade 60 is reciprocatingly fluctuated once, the aperture 60e crosses a shutter aperture 63 once at the forward fluctuating time and crosses it once at the backward fluctuating time. As the result, the aperture 63 is closed again from the opening start side by two crossing action. Thus, luminous flux passed through both ends of the aperture 63 becomes equal and the exposure irregularity at the peripheral part of the photographic picture frame on the photographic film is reduced.

Abstract: PURPOSE:To enhance response by installing an armature to a support using an eccentric spring, and by setting one of the ends of a coil spring, which couples and decouples a sprocket with from a gear, in engagement with said support. CONSTITUTION:An armature 70 is installed to a support 72 using an eccentric spring 74, and one of the ends of a coil spring 100, which fits No.1 boss fixed to a rotary shaft 32 and No.2 boss fixed to a gear 84, is put in engagement with said support 72. Accordingly, if a solenoid body 54 is deenergized,the armature 70 is disconnected from a rotor 58 quickly through the elastical eccentricity action of the above-mentioned eccentric spring 74. When this disconnection is made, the support 72 rotates a little to expand the coil spring, and now connection of No.1, No.2 bosses 82, 94 is released. Thus the response when the sprocket 42 is to be decoupled from the gear 84 can be enhanced.

Abstract: PURPOSE:To stabilize the generation of arc spots and to extend the lamp service life by making the porosity of the surface of the radiation space side of a base which consists of a porous metal larger than the surface of the opposite side, and impregnating an electron radiating substance into the pores. CONSTITUTION:A cold cathode 4 consists of a base 41 of a porous metal, and has pores 4 on the whole surface. And the porosity of a base body 41a facing the discharge space side is formed larger than the porosity of a base body 41b provided at the opposite side, and an electron radiating substance 43 is impregnated to the pores 42. As a result, the heat conductivity of the base body 41a is lowered and the temperature of the surface is raised, and arc spots are generated stably at the tip. And a plenty of substances 43 is impregnated to the base body 41a part of a larger porosity, and the substance 43 held in the pores 42 is replenished even though the substance 43 is lost on the surface, and thereby, the emitter function can be maintained for a long period. Consequently, the generation of arc spots can be stabilized, and the lamp life can be extended.
