Title: Dephosphorizing method of molten steel containing chromium
Inventor: TSUTSUMI NAOTO
IPC: C21C7/076
Filed: 1984-12-01
Abstract: PURPOSE:To execute dephosphorization refining without oxidation loss of Cr by adding a flux consisting of a Cr oxide, alkaline metal and the halide of an alkaline earth metal to the melt of a Cr-contg. steel. CONSTITUTION:The flux contg. 20-50% CaO, 10-70% CaF2 and 10-40% Cr2O3 is added to the molten steel at about 100kg for each one ton of the molten steel and the molten steel is refined at 1,500-1,700 deg.C in order to dephosphorize the Cr-contg. steel which contains <0.4% C, <0.1% P and 0.5-10% Cr and is refined in a converter, electric furnace, etc. to at least <=0.01% content of P. The P in the molten steel is oxidized to P2O5 by Cr2O3 and the P2O5 is fixed by the basic slag consisting of CaO and CaF2 and is converted to slag. The dephosphorization treatment is executed without the generation of harmful gaseous PH3 by the reaction of the dephosphorized slag with water and without the degradation of the Cr-contg. steel by the oxidation of the Cr in said steel.

IPC: G03B9/58
Filed: 1996-09-25
Abstract: PROBLEM TO BE SOLVED: To reduce the data storage amount of a storage means by calculating the timing of a shutter corresponding to an exposure after being inputted to a control means, on the basis of a set stop value, so as to control the operation of the shutter. SOLUTION: For reducing the storage of the storage means, data is provided on the basis of a stop value (F) set stepwise. In other words, an aperture area (Av) corresponding to each stop value, the output timing (Ts) of the opening/ closing operations of the shutter and an exposure amount (Ev) 0 are stored. When an exposure amount (Ev') at a certain stop value is different from the storage value of a data table, the output timing (Ts') is calculated by the control means, to control the starting timing of the shutter.

IPC: G03G21/00
Filed: 1990-09-21
Abstract: PURPOSE:To carry out reduction copying even with a cylindrical type by varying relative speed of an original and a light source, fixing the relative speed corresponding to reduction ratio, scanning the original with the light source for a corresponding number of times, and feeding recording paper to a photosensitive body only at a first scanning.

Title: Motor-driven air blower
Inventor: HAYATSU MAMORU
IPC: F04D29/059
Filed: 1997-09-18
Abstract: PROBLEM TO BE SOLVED: To prevent leakage of air to the air blowing fan side being the negative pressure side even under high pressure by putting one of a sealing plate in a noncontact condition from an inner ring in at least one of bearings. SOLUTION: When a motor part 5 is driven, an air blowing fan 8 installed on a shaft 6 of a rotor 3 rotates, and air sucked by this air blowing fan 8 passes through the inside of the air blowing fan 8, and is straightened by a guide blade 9, and changes the direction in an outer peripheral part inner wall of a fan cover 10 and a bracket 4 while recovering pressure, and is introduced to the motor part 5, and is exhausted from an exhaust port 1a of a motor frame 1 while cooling the motor part 5. When air exhausted from the air blowing fan 8 is exhausted from the exhaust port 1a, since an anti-air blowing fan side sealing plate 7f of a bearing 7A supported by a bearing housing 4a contacts with an inner ring 7a, high pressure air does not pass through the inside the bearing 7A to the air blowing fan 8 side being the negative pressure side.  Therefore, leakage of the air can be prevented, and high air blowing efficiency can be obtained.
