Filed: 1990-07-03
Abstract: PURPOSE:To reduce a change in distance measuring accuracy at the time of changing the distance of an object by finely moving an optical line sensor in its optical axis direction so that an image formation state on the optical line sensor is always in a high contrast state. CONSTITUTION:In a reference side optical system, a light beam passing an image forming lens 11A is reflected by a total reflection mirror 12A vertically to the optical axis and then reflected by a mirror prism 13 arranged between the mirror 12A and the optical line sensor 15 to form the image of an object on the sensor 15. A reference side optical system also similarly forms an object image on the line sensor 15 through an image forming lens 11B. Then distance measuring is started and the image of the object is projected to the line sensor 15. The line sensor 15 is finely moved in the optical axis direction to calculates the contrast in the image formation state. When the contrast is a maximum, the fine movement is stopped and phase difference operation is executed to calculate distance data.

Filed: 1981-10-30
Abstract: PURPOSE:To produce molten Fe-B metal inexpensively in a vertical furnace by bringing evaporated boron oxide and molten iron satd. with carbon into counter current contact with each other in coke packed layers. CONSTITUTION:Lumped coke is charged through a charging device 2 into a vertical furnace 1 to form packed layers. Hot wind from a hot stove 11 is blown through each tuyere and the reduced iron which is preliminarily reduced in a fluidized preliminary reducing furnace 6 is blown through upper stage tuyeres 3. Boron oxide or boric acid is blown through lower tuyeres 4 from a hopper 9. The preliminarily reduced iron is produced by reducing the powdery iron oxide supplied into the furnace 6 by using the waste gases of high temp. generated in the furnace 1. The boric acid is decomposed by heating and evaporates as boron oxide. The molten iron satd. with carbon dropping in the coke-packed layers between the upper and lower tuyeres and the gaseous boron oxide react by causing counter current contact with each other. If necessary, hot wind is blown through the tuyeres 5 in the lowermost stage to replenish the quantity of heat necessary for the reduction.

Filed: 1999-06-22
Abstract: PROBLEM TO BE SOLVED: To increase the auxiliary capacitance per unit area and to increase the opening rate in a liquid crystal display panel having pixel electrodes formed on an overcoat film which covers thin film transistors. SOLUTION: The pixel electrodes 15 are formed on an overcoat film 14.

Abstract: PURPOSE:To increase both the utilization rate and the life of a pasted electrode for a battery by fixing a pasty positive material principally consisting of nickel hydroxide over a perforated plate used as a core member, and pressing them until the core member is extended. CONSTITUTION:The symbol 1 represents a core member made of a perforated plate. The symbol 2 represents mixture powder which principally consists of nickel hydroxide 2' used as an active material, contains nickel and a graphite,  and contains an additive which enhances the utilization rate and the charge efficiency of nickel, such as cobalt or cobalt oxide, according to necessity. The symbol 3 represents a fiber. When the unextended core member 1 is extended by  being moved in the direction indicated by the arrow, the hole 1' of the core  member 1 deforms into the hole 1''. Here, such an extremely high pressure that  extends the perforated plate 1 should be applied to the core member, since a  high characteristic and an increased life similar to those of a sintered electrode cann't be realized only by pressing the core member through rollers. Owing to  such press as above, the discharge characteristic and the life of a pasted electrode are improved, and the capacity of the electrode can be increased.
