Title: Light source with reflecting mirror
Inventor: TARUMI KAZUO
IPC: F21V13/08
Filed: 1997-06-02
Abstract: PROBLEM TO BE SOLVED: To efficiently illuminate a material to be irradiated, without raising temperature by providing a reflecting mirror which is formed by depositing an infrared ray transmitting film to glass as the board and a cover glass having a light-interfering film, and a light source. SOLUTION: This device is provided with a reflecting mirror 3 formed by depositing an infrared ray transmitting film, which transmits infrared ray and which reflects visible light, to an inner surface and/or outer surface of a glass board 1, having an opening in a front surface 13 thereof and a neck part 11 in a rear part thereof and a radial surface or a curved surface formed into a rotary elliptic surface at an inter mediate part thereof, and provided with a cover glass 6 arranged in front of the reflecting mirror 3 and formed with a light-interfering film 7, which transmits visible light and which reflects the wavelength area except for the visible light including infrared rays, in at least the inner surface thereof. A filament is arranged inside of a bulb made of quartz glass, for example, and the halogen gas and the like is filled in the bulb.  A light source is arranged optically opposite to the reflecting mirror. Consequently, since the infrared rays are not radiated forward of the cover glass 6, the temperature of the material to be irradiated does not rise.

Title: Forming method of polycrystalline semiconductor thin film
Inventor: ASANO AKIHIKO
IPC: H01L21/20
Filed: 1993-06-16
Abstract: PURPOSE:To enhance a polycrystalline semiconductor thin film in grain diameter so as to use it as material for the active region of a semiconductor element by a method wherein a region of an amorphous semiconductor thin film is crystallized into a crystallized region as it is kept at a higher temperature than the other region of the semiconductor thin film that remains amorphous, and thereafter a polycrystalline layer is made to grow all over the surface of the thin film through thermal decomposition. CONSTITUTION:An amorphous silicon thin film 2 is grown on a substrate 1. Light pulses are condensed by a convex lens and turned into an optical beam 4, and the optical beam 4 is made to irradiate the substrate 1 through a slit as the substrate 1 is moved in a direction of an arrow 3 and in another direction vertical to the former so as to enable square regions 5, each 10X10mu<2>, to be alternately crystallized on the amorphous silicon film 2 at both a lateral interval of 50mum and a longitudinal interval of 50mum. Then, a specimen where the regions 5 are crystallized is irradiated with infrared rays radiated from an infrared lamp to selectively heat the crystallized regions 5, whereby the amorphous silicon regions 2 are heated through thermal conduction from the regions 5. A polycrystalline silicon thin film 7 is made to grow through a local hot CVD method till it covers all the surface of the amorphous silicon thin film 2.

Filed: 1997-06-02
Abstract: PROBLEM TO BE SOLVED: To provide a control system for an electronic still camera in which an optimum layout is set by confirming a photographing layout in advance, even under a dark environment. SOLUTION: An entry means 21 is used to select the 'pre-shutter mode'. After a mode selection is detected by a CPU, when a shutter button 4 is half- depressed, a 1st flashing is conducted.

Inventor: KOHAMA TAKAYUKI
IPC: G11B23/087
Filed: 1988-06-14
Abstract: PURPOSE:To obtain a tape guide which can withstand a long period of application by forming the thermoplastic or thermosetting resin into a hollow cylindrical form by an injection molding process, etc., and grinding the surface of said cylinder to form the minute recessing/projecting parts in the direction orthogonal to an axis. CONSTITUTION:A tape guide main body 10 made of the thermoplastic or thermosetting resin is formed into a hollow cylindrical form by an injection molding process, a compression molding process and an extrusion molding process. Then the surface of this cylinder is ground with a centerless method by a grindstone having the proper roughness. Thus a minute recessing/projecting surface 11 having the 0.4-0.6RZ surface roughness is formed in the direction orthogonal to an axis. This guide 10 functions to guide a magnetic tape 14 between a supply reel 12 and a take-up reel 13 set on a base stage A. The frictional resistance is reduced to the tape 14 owing to the surface 11 formed on the surface of the guide 10. Then the fine dust stays in the recessing part and no scratch is produced to the tape 14 and the guide 10.

Title: Digital-analog converter
Inventor: KASUGA MASAO
IPC: H04B14/04
Filed: 1982-08-21
Abstract: PURPOSE:To increase the accuracy of D/A conversion by about one bit, by converting the quantizing level so as to set the mean value of signals at two sampling points which are adjacent to each other to the level approximated to an original analog signal. CONSTITUTION:A digital signal processing circuit 5 samples an analog signal and produces a digital signal of (m) bits. A quantizing level converting circuit 6 shifts the signal supplied from an input terminal 10 to the left by one bit by means of ALU11 and has subtraction to a signal yn-1 of an output terminal 14. A signal processing circuit 12 performs a rounding process, etc. to obtain a differential signal of (n) bits. This differential signal is held at an output register 13. The (n)-bit signal is turned into an analog signal by a D/A converter 7 consisting of a D/A converting part 7a and an S/H converting part 7b and then delivered via an analog LPF8. The circuit 6 converts the analog signal into a differential signal between an (m)-bit signal and an (n)-bit signal which is preceding one sampling time. Thus the accuracy is improved by about one bit for D/A conversion.
