Filed: 1992-11-04
Abstract: PURPOSE: To simplify the assembling work by bringing an electrode segment into contact with a bottom plate of a conductor, and fixing the same to a conductor which is installed in the shape of ring, and extended in a non- conductive ramming mass. CONSTITUTION: An electrode segment 1 is fixed to a bottom plate 3, and a segment conductor is welded to the segment 1. A hearth lining of a DC electric arc furnace is formed by a non-conductive ramming mass 2 which is lined inside a cavity between the segment conductors so that an upper front face 20 is just kept into contact with a pool 17. A center of a bottom part, and a radial external area are also formed by the mass 2. A main electric furnace comprises a lower container and an upper container, and a container wall 19 is installed. The segment 1 is installed in such manner that the segment conductor does not exist on a central area of the bottom part not having the segment of a cathode 8 which is formed in the shape of the movable upper electrode. Thereby the assembling work can be simplified with the low cost.

Filed: 1998-10-19
Abstract: PROBLEM TO BE SOLVED: To prevent the characteristic of a film from being changed because of gas generated from an incorporated power source battery by using a lithium battery as the power source battery driving an information imprinting device for imprinting information on the photographic film and to make a photographic film unit with lens compact by miniaturizing the power source battery. SOLUTION: The lithium battery 5 is used as the circuit power source of the date imprinting device 1 so as to feed power to a clock circuit, a liquid crystal panel 3 and a light emission control circuit. By the light emission control circuit, an LED 2 is turned on for a fixed time by receiving a signal indicating that a switch SW1 is turned on. Since the switch SW1 is instantaneously turned on when a shutter blade included in a shutter mechanism 8 is fully opened, a date is imprinted at the same time as a photographing action is executed. Besides, an alkaline manganese battery is used as the power source for a data imprinting device and the power source for a stroboscope. Thus, the load of the battery 5 can be reduced and the reliability of the date imprinting device 1 can be maintained over a long time.

Title: Combustion device
Inventor: ITO SEIICHI
IPC: F23L7/00
Filed: 1985-12-27
Abstract: PURPOSE:To restrain the burning temperature of the layer of coke and elongate the life of a pipeline by a method wherein the inner end of a conduit, wound into spiral, is raised up from the bottom of a combustion vessel to form an opening end for injecting gas, containing moisture, into the combustion vessel. CONSTITUTION:A combustion furnace 1 is filled with coke and the coke is ignited from the bottom part thereof. When the coke is burnt in some degree, air or oxygen is guided into a conduit 2 under bubbling from an opening at the end 2a of the conduit 2 extended into a water tank 3. Then, the bubbling air or oxygen arrives at the opening of the inner end 2b of the conduit 2 and flows into the layer of coke. During passing through the conduit 2, the bubbling air or oxygen is heated gradually to a high temperature and flows out of the opening of the inner end 2b into the layer of coke. Oxygen gas in outflow high-temperature gas promotes the oxidization of the layer of coke while water vapor reacts with the coke and produces water gas partially, then, the water gas is burnt. Combustion heat in this combustion reaction will never go so high as before and the damage of the inner end 2b of the conduit 2 may be restrained remarkably.

Abstract: PURPOSE:To prevent a double or triple image from being formed owing to reflection on many surfaces and to secure the brightness of a display image by providing a windshield with a polarizing direction adjusting means, making S-polarized light or P-polarized light on its internal surface at a Brewster angle, and eliminating reflection on the internal or external surface of the windshield. CONSTITUTION:Light which is transmitted in the windshield 4 as to display light which is made incident on the internal surface of the windshield 4 has its polarizing direction rotated by 90 deg. through the polarizing direction adjusting means 5, and neither the P-polarized light which is made incident at the Brewster angle nor P-polarized light which is projected from the external surface are reflected by the surface. Therefore, the S-polarized light with is made incident on the internal surface of the windshield 4 at the Brewster angle is reflected with a constant reflection factor to form a display image in the front visual field of a driver. At this time, the S-polarized light which is not reflected, but transmitted through a reflecting layer is made into P-polarized light by the polarizing direction adjusting means 5 and the P-polarized light travels to the external surface of the windshield 4 at the Brewster angle, so only the reflection on the external surface is eliminated. Consequently, the brightness of the reflected display image is secured, a double image is eliminated, and the visibility is improved.
