Title: Steel sheet having excellent brightness of reflection and workability
Inventor: YAMAMOTO TAKESHI
IPC: C22C38/00
Filed: 1987-06-04
Abstract: PURPOSE:To provide a steel sheet having excellent brightness of reflection and workability by forming a smooth part to be formed on the surface of the steel sheet to a continuous single face and specifying the range of fluctuations in the projection area and depth of microrecesses. CONSTITUTION:The smooth part having <=3mum Rmax is formed on the surface on at least one side of the steel sheet and the microrecesses having >=5mum depth are disposed evenly at the rate of 10-50 pieces per mm<2>. The smooth part is formed as a continuous single face and the fluctuations in both the projection area and the depth per piece of the microrecesses are specified within a + or -20% range. This steel sheet is produced by rolling the same with rolls subjected to surface working to impress prescribed patterns to transfer the patterns to the steel sheet or by other method in the temper rolling which is the final process of the rolling. The steel sheet has the excellent beauty of the surface after painting in addition to the excellent press formability.

Title: Method and device for surface treatment in bath
Inventor: SHIMAMURA KOUICHI
IPC: C25F7/00
Filed: 1982-08-12
Abstract: PURPOSE:To perform extremely easily and surely partial plating of a pattern on work, stripping of plating, etc. by providing oppositely the work and discharge needles at a very close distance in an electrolytic surface treatment bath, and applying a prescribed voltage and current to both. CONSTITUTION:The work 7 is inserted into the plating soln. in a plating bath cell 1 while the work is sandwiched with metallic rolls 5, and the flatness thereof is maintained by a work holder 6. While the repulsive force of a leaf spring 10 is exerted on the rear of the work 7 with a plate 11 in the holder 6, the work 7 is held in the guide groove 9 of a holder body 8, so that the narrow spacing (0.01-0.005mm.) from discharge needles 13 is maintained. A prescribed pulse voltage is applied between an anode A and a cathode, and noble metal is plated on the position to be plated of the work 7 corresponding to the needles 13. Since the plating current is inversely proportional to the distance between the needles and the surface to be plated, the plating current concentrates at the surface to be plated nearest the needles 13, whereby the plating of a very small part is made possible.

Title: Illumination device, and original reader and reproducer
Inventor: HINO MAKOTO
IPC: H04N1/04
Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To evenly illuminate an original with high illuminance and to prevent occurrence of shadows of the original by diffusing and reflecting the luminous flux sent from a light source and illuminating the original from a point set right under it by means of a cylindrical member having a diffusion/reflection film. SOLUTION: The luminous flux sent from a light source 7 is led into a cylinder 2 from a reflector 8 through a 1st opening 4 for illumination of the interior of the cylinder 2. Then the luminous flux is repetitively diffused and reflected in the cylinder 2 via a diffusion/reflection film 3 after illumination of the inner wall of the cylinder 2, and the luminous flux is partly emitted through the openings 4 to 6 of the cylinder 2. The luminous flux emitted through the 2nd opening 5 is made incident on an original put on the contact glass 1. The 2nd and 3rd openings 5 and 6 are placed opposite to each other, and the information recorded on the original surface can be read by a reading optical system through the opening 6. The opening 5 is set at a position right under and very close to a reading position R.  Furthermore, the even illumination is secured through the proper adjustment of width of the opening 5.

Title: Seedling box washing machine
Inventor: KAWASHIMA KENZO
IPC: B08B3/02
Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To make it possible to surely execute washing by smoothly transporting seedling boxes even at the time of being pot-type seedling boxes or seedling boxes being different in measure and shape. SOLUTION: When the seedling box is pushed-in from a supply port 4a, a guide member 19 flexibly pressurize the seedling box towards upper brushes 25 and an upper guide bar body 17 with a support bar, which is energized upwards by the repulsive force of a pulling spring 28. Therefore, even a pot-type seedling box provided with a flexibility is smoothly carried without being bent so as to be surely washed. Besides, the support bar 27 which is normally energized upwards by the pulling spring 28 is abutted on the lower surface of a spacer 30 so that the outer peripheral surface of a guide roll 27a is made to be a state where it is not protruded from the upper surface of the guide member 19.  The state can be changed-over into the one where the outer peripheral surface of the guide roll 27a is slightly protruded from the upper surface of the guide member 19 by directly abutting the support bar 27 on the lower surface of the guide member 19.

Abstract: PURPOSE:To improve the effect of ink presetting for printed matter where a pattern is extremely small by making specific corrections at each measurement point for a plate other than a 'SUMI' (Japanese ink), and totalizing respective corrected data by ink zones and finding an area rate. CONSTITUTION:When the pattern area rate of the color plate other than the 'SUMI' plate is corrected, various alteration is possible and performed by programmed processing by utilizing a microcomputer, etc. For example, three methods are programmed and one of them is selected. In the 1st method, the pattern area rate of each beam spot 5 is set to 0% when the area rate is smaller than a specific value and the value obtained by multiplying the measured value by a specific number is employed as a corrected rate when not smaller than the specific value. In the 2nd method, the pattern area rates of nearby spots 5 are averaged and specific corrections are made according to whether the mean rate is smaller than the specific value or not. In the 3rd method, the pattern area rate of the measured spot 5 is multiplied by the specific number when not smaller than the specific value, a bit indicating the presence of a pattern is set in a corresponding address of a pattern presence/ absence table, and specific corrections are made by ink zones 2 according to whether or not there is a pattern.

Title: Minute processing method
Inventor: YAMANAKA EIJI
IPC: H01L29/76
Filed: 1979-11-02
Abstract: PURPOSE:To make unnecessary a mask for selectively exposing to light the surface of a substance to be processed and the adjustment of the mask position by a method wherein the surface, which is uneven and has a step in the surface level, is coated with organic matter in such a way that opening is made in the portion desired. CONSTITUTION:An SiO2 film 2 is formed on the whole surface of an Si substrate 1 which is uneven and has a step in the surface level. Next, a negative type photoresist film 3 is applied onto the film 2, using a spinner, for instance. The film 3 is immediately heat-hardened, and then an opening 4 is made in the side part near the top of the projection. Then, the film 3 is totally removed after selectively removing the film 2 exposed to the opening 4 through etching. Thus, it is made unnecessary to employ a mask for selectively exposing to light the surface and adjust the mask position to a substance to be processed, while the side only of the substance to be processed with an uneven surface can readily be processed inexpensively.
