Title: Manufacture of grating element
Inventor: BABA NOBUYUKI
IPC: G02B5/32
Filed: 1987-11-19
Abstract: PURPOSE:To manufacture a large-area grating with deep grooves at low cost by removing a Fresnel diffraction trace place formed by a two-luminous-flux interference method and forming two kinds of gratings, and matching the positions of the gratings by using reproduction light and sticking them together. CONSTITUTION:Resist 41 on a base material 40 is exposed by the two-luminous- flux interference method and developed to form a holographic grating 44, Ni is sputtered thereupon to form a conductive film 45, and Ni electrocasting is carried out. Then, a protection film is formed on the obtained die 46 and a pattern B which does not have any influence of a Fresnol diffraction trace A is punched. Thus, dies 46a and 46b having different patterns are formed. Then while the positions of the gratings 44a and 44b are matched by using the actual reproduction light, they are stuck on the substrate 47 to obtain a die. Then ultraviolet-ray irradiation resin 48 is applied on the die and an acryl substrate 49 is superposed and irradiated with an ultraviolet ray 50 to manufacture a hologram element 25.

Abstract: PURPOSE:To improve magnetic characteristics by oxidizing and burning an aqueous solution of a nonvolatile organic compound and ZnO or a compound to produce ZnO and an aqueous solution of a mixture of an iron chloride and a chloride of one or more metals from Mn, Ni and Mg. CONSTITUTION:ZnO or a compound such as ZnCO3 to become ZnO by heating is blended and dispersed into an aqueous solution of a nonvolatile organic compound such as aqueous solution of PVA to prepare a slurry.

An average rotating speed in explosion stroke is found out per cylinder, and also the deviation between average rotating speeds of respective cylinders in which explosion strokes are caused one by one, and the deviation between average rotating speeds of respective cylinders continously acting precedent thereto by a crank angle 360 deg., and an average rotating speed change amount is calculated from those deviations. The average rotating speed change amount is compared with a misfire judging value so as judge presence of misfire. When the difference between an engine rotating speed and the average rotating speed is a prescribed fluctuation width or more, forced misfire is carried out.

IPC: C21D1/06
Filed: 1997-10-14
Abstract: PROBLEM TO BE SOLVED: To improve the strength such as fatigue strength of a maraging steel, at the time of executing an age precipitating treatment, by executing a carburizing treatment at a temp. in the age precipitating treatment. SOLUTION: After a maraging steel is processed by a solution treatment at about 800 deg.C, it is executed by an age precipitating treatment at 450 to 500 deg.C for about 1 to 4 hr to toughen the material thereof. In this case, the maraging steel is executed by a carburizing treatment at the temp. in the age precipitating treatment. The carburizing treatment may be executed by a gas method, a liq. method, a plasma method, an electrolytic carburizing method or the like. By thermodynamically unstable elements such as Ni, Co or the like contained in the maraging steel, the activity of iron is reduced and the carburization is sufficiently progressed at the treating temp. without forming a cementite layer on the surface of the steel. In this way, the maraging steel is processed by the age precipitating treatment to toughen it and simultaneously, to increase its strength.
