Title: Electrophotography printing device
Inventor: HASHIMOTO YASUSHI
IPC: G03G21/00
Filed: 1988-04-08
Abstract: PURPOSE:To hold feeding of a photosensitive body with high accuracy, and also, to automatically replace the photosensitive body by a button operation or a microprogram by forming the photosensitive body to a sheet shape and winding it up to a drum-shaped holding body. CONSTITUTION:By a loading signal, a roller 6 takes out one sheet of photosensitive sheet 2 from a tray 3 and it is allowed to pass through a gap of a drum 1 and the tip is held by a roller 7. Subsequently, the drum 1 is rotated counter-clockwise and the sheet 2 is allowed to adhere closely by a roller 10. When a roller 9 reaches a position of a push-in device 8, the push-in device 8 operates and the rear end of the sheet 2 is allowed to pass through the gap of the drum 1 and pushed into the roller 9, held and returned. Next, the roller 10 draws back and loading is completed. In case of replacing the sheet 2, when a discharge signal is applied, the roller 10 presses the sheet, the torque which has been applied to the rollers 7, 9 is eliminated and tension of the sheet 2 is eliminated. Thereafter, when the rear end of the sheet 2 is released and the roller 10 is brought to drawback, the rear end comes out of the gap of the drum 1. Subsequently, the sheet is pressed by the roller 10, the drum 1 is rotated clockwise, the sheet 2 is peeled off from the drum 1, and when the roller 7 has reached the vicinity of the roller 10, the roller 7 releases the tip of the sheet.

IPC: G11B19/12
Filed: 1984-05-04
Abstract: PURPOSE:To omit a light emitting matter of high luminance used at a light emitting part as well as a photodetecting matter of high sensitivity used at a photodetecting part respectively and therefore decreasing power consumption, by using a reflector containing plural faces having proper angles of reflection and leading the center part of the luminous flux to plural photodetecting parts. CONSTITUTION:The luminous flux reflected by a light emitting part 1 is reflected again by a reflecting part 6 containing a reflector consisting of two reflecting faces 6a and 6b having proper angles of reflection. Then the right half of the luminous flux reflected by the face 6a transmits a turntable 3 and reaches a photodetecting part 4. While the left half of the luminous flux reflected by the face 6b transmits the turntable 3 and reaches a photodetecting part 5, respectively. Thus application of the center part of the luminous flux delivered from the part 1 can omit a light emitting matter of high luminance used at the part 1 as well as a photodetecting matter of high sensitivity used at a photodetecting part respectively for an optical size detector.

Title: Condenser with deaeerator
Inventor: YASHIRO HIROTSUGU
IPC: F28B9/10
Filed: 1994-04-26
Abstract: PURPOSE:To improve deaeration effect by providing a deaerator and a condenser side by side, an orifice through which upper parts communicate with each other and an orifice through which lower parts communicate with each other and steam-injecting pipes and steam blow-off ports which form a plurality of extending parts branching and directed downward in the deaerator. CONSTITUTION:When steam is directly blown off into water from a plurality of steam blow-off ports 21, the water is heated and stirred and thus deaerated. The steam is condensed and mixed in the water. Deaerated air enter a main condenser from an orifice 15 at the upper part of a deaerator and exhausted from an air ejector pipe. The water on the bottom of the deaerator passes through P orifice 22 and enters the main condenser. At this time, pressure reduction and boiling are generated in the orifice 22 due to pressure difference between the deaerator and the condenser so that vapor is discharged from the water. Since the low pressure side of the orifice is a space exhausted by a vacuum pump 9, the deaeration effect thereof is high. Since the steam blow-off ports 21 with simple structures have the deaeration effect more remarkable than a tray, the tray is not needed.

Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To make the implement usable over a wide area for signboards, electrical illumination of store entrances, etc., by forming plural recessed curved surface parts for diffusing light to the inside surfaces of housing recessed parts for housing LED lamps and forming at least a part of the outside surfaces thereof as curved surfaces. SOLUTION: Translucent covers 2 are so formed that the upper parts thereof have an approximately conical shape and the lower parts in succession thereto are formed to a cylindrical shape. The housing recessed parts for housing the LED lamps 4 are formed within these covers 2 and the recessed curved surface parts for diffusing the light cast from the LED lamps 4 to the outer periphery side of the covers 2 are formed. In such a case, the spherical hole parts 2b, sectionally arc-shaped groove parts 2c and sectionally arc-shaped longitudinal groove parts 2d formed in the housing recessed parts intricately reflect and refract the light from the LED lamps 4 and diffuse the light through the covers 2 to their peripheral side parts.  As a result, the circumferences of the light emitting implements 1 are brightly illuminated when the light emitting implements 1 are used by mounting the implements at electrical illumination signboards, etc., and, therefore, the signboards, etc., are distinctly visually recognized not only from the front surface side of the light emitting implements 1 but from the peripheral flanks thereof as well.

IPC: B23K9/04
Filed: 1983-05-23
Abstract: PURPOSE:To eliminate the cracking occurring in formation of an Al-Ni alloy by underlaying an Fe-Ni material having a specific Fe:Ni ratio on an iron or steel base then build-up-welding Al bronze contg. Ni at a specific value or below thereon as the 1st overlay layer. CONSTITUTION:An Fe-Ni material contg., by weight, <=70% Fe and >=30% Ni is build-up-welded as underlaying on an iron or steel base to prevent penetration of Cu into said base prior to build-up welding of Al bronze. Al bronze contg. <=7% Ni is build-up welded as the 1st overlay layer on said underlay layer. The rate of dilution in the underlay part is decreased to about 4% and the content of Ni in the overlay layer is suppressed to about <=7% by a soft plasma method. The penetration of Cu to the iron grain boundary is thus eliminated and the generation of cracking occurring in the formation of an Al-Ni alloy in the welded overlay layer of the Al bronze is obviated, by which the defectless build-up weld zone is obtd.
