Abstract: PURPOSE:To reduce the nonuniformity in the characteristics of field effect transistor elements and to make reproducibility excellent by a method wherein openings of a gate pattern are formed in a first insulating film, a semiconductor substrate under some openings is etched selectively, then a second insulating film is connected thereon, the second insulating film in the vicinity of the openings is removed selectively in relation to the first insulating film, and recess etching is applied to the semiconductor substrate under the openings to form gate electrodes. CONSTITUTION:Openings of a gate pattern are formed in a first insulating film provided on a semiconductor substrate, and necessary etching is applied to the semiconductor substrate under these openings only for elements whose recesses of an E mode or the like are deepened. Then, a second insulating film is provided, and source and drain electrodes are formed. Thereafter the second insulating film in the vicinity of the openings is removed selectively in relation to the first insulating film so as to expose the semiconductor substrate under the openings, and recess etching is conducted with the gate pattern of the first insulating film used as a mask. Since the resist thickness, exposure, development, etc. of this first insulating film can be controlled easily to optimum conditions, the pattern is formed with reduced nonuniformity and excellent reproducibility.

Title: Light source equipment in optical scanner
Inventor: OSAWA TAKAYUKI
IPC: H04N1/113
Filed: 1992-02-24
Abstract: PURPOSE:To attain the optical scanning with a high light utilizing efficiency by arranging an anamorphic optical system toward a semiconductor laser array from an aperture so as to reduce a light interruption quantity by the aperture shaping the light spot shape. CONSTITUTION:Each micro lens MLi has a positive power and a radius of curvature of a face of the lens in a direction corresponding to the main scanning, is set larger than that in a direction corresponding to the subscanning. Thus, each lens has a stronger positive power in a direction corresponding to the subscanning than that in a direction corresponding to the main scanning. Since an angle made between a direction corresponding to the main scanning and an array direction is a very small angle, a square micro lens in the micro lens array 20 has a stronger positive power in the direction Y than that in the X direction. Thus, a laser luminous flux passing through the array 20 is effectively suppressed in the divergence in the broadwise direction of the aperture, and when the light is made incident in a light spot shaping aperture in a condenser lens, the luminous flux shut in the broadwise direction of the aperture is decreased and the reduction in the light utilizing efficiency by the aperture is prevented.

Filed: 1979-03-27
Abstract: PURPOSE: To rotate a turbine in a pipe and rotate a power generator effectively by a method wherein two floating bodies are moved up and down alternately by sea waves, two pistons are moved up and down alternately, and thereby gas in a pair of cylinders is sent into a pipe.  
     CONSTITUTION: At the time of operation, the direction of sea waves is detected, and by operating rotary device 2 at the center of support 1, upper half part 1a of the support is turned by a required angle, and a pair of floating bodies 10 are placed to match the direction of sea waves W. By operating inter-floating body interval adjusting device 12, the distance between two floating bodies 10 is set at half the wavelength. By this, when one floating body 10 is at wave crest Wt, the other floating body 10 comes to wave trough Wb, and thereby both floating bodies 10 are moved up and down alternately with the maximum amplitude. As a result, pistons 5 in two cylinders 3 move up and down alternately, and air in each cylinder 3 moves back and forth in pipe 6. As a result, turbine 7 is rotated, and power generator 8 is driven.

Abstract: PURPOSE:To make an accurate optical measurement possible, by adding a polyoxyethylene secondary alkyl ether or polyoxyethylene fatty acid ester having an HLB value within a specified range to a humor to remove turbidity in the analysis of components of the humor. CONSTITUTION:One or more kinds of polyoxyethylene secondary alkyl ether or polyoxyethylene fatty acid ester with an HLB value (which indicates a working relationship between the hydrophilicity and hydrophobicity of a surfactant, whereby the larger value corresponds to a higher hydrophilicity) of 11.5-14.0 is added to a humor (serum or the like) or a reagent for determining humor components. If necessary, a small amount of a turbidity inhibitor, for example, a 1-8C alkyl alcohol, a non-ionic or anionic surfactant with an HLB value of 13.8-18.0 or an 8-16C alkylbetaine is added. Thus, the turbidity in the optical quantitative analysis of components to be measured in a humor is made soluble to make an accurate measurement possible.

Title: Charging apparatus for raw material to blast furnace top
Inventor: SETO SHIYOUZOU
IPC: C21B7/20
Filed: 1978-03-31
Abstract: PURPOSE:To extend the service life of distributing shoots and to reduce equipment cost, by installing, in a bell-less type blast furnace, revolvable and inclinable raw- material-distributing shoots under a fixed hopper, and by mounting the driving mechanism for the shoots at the outside of the furnace. CONSTITUTION:A bell-less type blast furnace is equipped with a fixed hopper 2, which serves simultaneously as a shield for heat in the furnace, at the furnace top. Under the hopper 2 is installed raw-material-distributing shoots 5 which are revolvable and inclinable. A driving mechansim (a cylinder 9 for inclining, a revolving devive 14) of the shoots 5 is attached at the outside of the furnace so that is undergoes no direct effect of radiated heat or dust present in the furnace. Hereby, the distributing shoots has long service life without being broken through wear because the charged material enters once into the fixed hopper 2, where it is stirred, then moves  to the distributing shoots, instead of falling directly to the shoots 5. The driving mechanism for the distributing shoots is hardly damaged by heat or dust because it is installed at outside of the furnace.

Title: Game machine
Inventor: IOKI SADAO
IPC: G07F7/08
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To provide a game machine capable of making conversion from a security value to a game value due to the illegal flaudulent alteration of a game information medium (prepaid card, for instance) difficult. SOLUTION: When ball lending corresponding to one input of a ball lending button is ended, (when ball lending request signals (BRDY) become inactive), inhibition time for inhibiting the ball lending of a next time is set. Thus, the security value of the prepaid card can not be continuously converted to the game value (lending ball number). Even when the security value of the prepaid card is to be continuously converted to the game value (lending ball number), long time is required for continuous conversion. Thus, the illegal operation of a player is easily monitored by a shop clerk.
