Title: Roll stand for guiding cast billet
Inventor: UCHIMOTO YOSHIKAZU
IPC: B22D11/128
Filed: 1979-07-09
Abstract: PURPOSE:To make easy the replacement of the roll unit, by putting the roll unit into the U-type frame made of thick steel plate, by rigidly setting the screw for adjusting the roll gap of this roll unit to the open mouth of the frame, and by bearing the force of hydrostatic pressure of the molten steel for continuously casting the billet, and the reaction force against the straightening work, at the center of the frame. CONSTITUTION:In the second cooling zone of the bending part of the bending type continuous casting apparatus, the billet guide roll stand 1 is constituted of the U-type frame 4 made of heavy thick steel plate, the lower roll unit 6 put in the hollow space 5 of the frame 4, the upper roll unit 7, and the screw 8. Since the screw 8 is fixed to the frame 4, even if the force of hydrostatic pressure of the unsolidified molten steel within the continuously cast billet, or the reaction force against the straightening work, is loaded on the screw 8, the force is born by the center of the frame 4, and besides, the force is turned into the bending stress in the direction of pathway of the billet and the tensile stress of the frame 4. Moreover, since the frame 4 is made of heavy thick steel plate, the strength is great, and the weight of the frame 4 can be reduced as compared with the conventional block type, and the replacement of upper and lower roll units can be easily worked.

Title: Image pickup device
Inventor: FURUYAMA IWAO
IPC: G02F1/133
Filed: 1992-04-08
Abstract: PURPOSE:To correct the backlight with a simple constitution by controlling the transmittance of a liquid crystal panel based on the inverted signal of the luminance signal at the time of photographing in the backlight state. CONSTITUTION:At the time of photographing in the backlight state, a backlight correction switch 14 is operated to turn on a changeover switch 12, and a luminance signal Y outputted from a luminance signal processing circuit 7 is inputted to an inverting circuit 11. The circuit 11 inverts the signal Y to invert the black and white of the picture projected on a liquid crystal panel 3. Consequently, an abnormally high luminance part for photographing in the backlight state is projected as a dark picture on the panel 3, and the light transmittance of this part is reduced. Light transmitted through the panel 3 is photoelectrically converted by a CCD 4 and is supplied to an iris control circuit 10 to control the diameter of an iris 2. Thus, the backlight is easily corrected without requiring many integrators or the like.

Title: Three-dimensional information input camera
Inventor: HAMADA MASATAKA
IPC: G01B11/24
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To obtain a pattern filter with durability by constituting a pattern filter of a plurality of layers of laminated components laminated in a fringe shape on a substrate. SOLUTION: A xenon tube to emit flash light, a concave lens to project a pattern widely toward a subject, and a mask pattern unit with a pattern filter are provided inside a fringe pattern projecting part. In the pattern filter, the number of fringe patterns is, for example, 10-30 periods, and each fringe has a concentration distribution. By the concentration distribution, pattern light transmitted through the pattern filter forms a fringe-shaped projection pattern in the subject. By receiving the fringe-shaped projection pattern and detecting the phase shift of the pattern, it is possible to obtain a phase image i.e., a distance distribution image (two-dimensional image). The concentration distribution of the pattern filter may be a combination of a monotonously increasing part and a monotonously decreasing part in theory, and each may be a sine wave or a Gaussian distribution.

Abstract: PURPOSE:To increase the withstanding voltage at an edge part and to improve insulation reliability, by providing an insulating film on the edge of a conductor sheet, and shortening the length of a winding stack. CONSTITUTION:At a part constituting conductor sheets 7 and insulating sheets 8, which are wound around a transformer, an insulating film 10 is provided on an edge 9 of each conductor sheet 7.
