Title: Method of measuring light ray at irradiated surface
Inventor: WATANABE KAZUNORI
IPC: G01J1/00
Filed: 1990-11-08
Abstract: PURPOSE:To eliminate the necessity of repetitions of calculation from a light source to a reflecting surface or the like by using the reflecting surface or the like which is irradiated by the light source, as a secondary light source. CONSTITUTION:Reflecting light Ir is obtained by incident light Io, and a reflection diffusive surface D is produced by this reflecting light Ir. When a viewer 19 takes a position as shown, the volume of light incident upon this viewer can be obtained in accordance with a position at which a line drawn to the viewer 19 crosses the reflection diffusive distribution D. That is, the component is in that direction is a diffusion light component directed to the viewer 19. The diffusion light component is dependent upon an angle theta between a reflection beam vector and a sight direction vector of the viewer 19. Thus, in consideration with the reflection diffusive distribution for every reflection light, the reflecting surface is regarded as a secondary light source by storing a suitable number of reflection light rays in memory, thereby it is possible to create an image having a high degree of loyalty.

Title: Manufacture of semiconductor device
Inventor: IWAI KAZUO
IPC: H01L29/78
Filed: 1995-11-21
Abstract: PROBLEM TO BE SOLVED: To prevent the short-circuit of high melting point metal silicide between a gate electrode and a source drain, via a side wall. SOLUTION: After a gate electrode 3 composed of polycrystalline silicon is formed, a silicon oxide film of about several 100Åin thickness is formed, and a silicon nitride film 6 of about several 1000Å in thickness is continuously formed. Anisotrotic etching is so performed that the silicon nitride film 6 is left only on the side wall of the gate electrode 3. In this process, the silicon oxide film 5 is also etched at the time of overetching of the silicon nitride film 6, so that the side wall protrudes from the upper surface of the gate electrode 3. After that, a high melting point metal thin film is formed, heat treatment is performed, and an unreacted high melting point metal is eliminated. Thus a silicide layer 10 is formed on the surface of the gate electrode 3 and on the surface of a diffusion layer.

SOLUTION: An optical fiber 1 is wound on a bobbin 2 so that one end can be fed, nipped between a pair of feed rollers 10 of a feeding device 3, and fed out at a fixed speed from the top end of a guide pipe.

Title: Paper sheet feeder
Inventor: KIYAMA TOSHIHIKO
IPC: B65H5/06
Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To reliably supply a paper sheet to a normal position by arranging a one-way rotary clutch which is arranged on an upstream side feed roller and can freely rotate the upstream side feed roller in the paper feeding direction of the paper sheet when back tension is generated in the paper sheet. SOLUTION: When large back tension is generated in a paper sheet 2, a force to rotate it in the clockwise direction at a rotating speed larger than the rotating speed of a driving shaft 20, acts on a first upstream side feed roller part 11a through the paper sheet 2. As a result, since a one-way clutch 12 is actuated and cuts off a torque transmitting passage to the first upstream side feed roller part 11a through the driving shaft 20 from a rotational driving source, an upstream side feed roller 11 freely rotates in the clockwise direction. That is, since the paper sheet 2 is manually fed in a condition where a downstream side feed roller 16 mainly drives and the upstream side feed roller 11 is driven, a skew of the paper sheet 2 is corrected.
