Patent JP-H10307203-A (JP)
Title: Diffraction grating
Inventor: KOMIYAMA MAKOTO
IPC: G01J3/18
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To prevent stray light from being made incident on a photodetector and to eliminate the influence of the stray light caused by the reflection of a glass plate by inclining and sticking the glass plate at a fixed angle to a direction perpendicular to a diffraction direction. SOLUTION: A resin layer 2 is formed on glass base material 1 and further grooves (a) are plurally formed in parallel with each other on the resin layer 2. The glass plate 4 is stuck to the surface side of the layer 2 through adhesive 3a. The plate 4 is kept parallel in terms of attaching accuracy to the layer 2 with respect to the direction (diffraction direction) orthogonally crossed with the grooves (a) and stuck to be somewhat inclined (b) by the fixed angle θwith respect to the direction along the groove (a) (direction perpendicular to the diffraction direction). Thus, the stray light 103a is emitted with a fixed angle difference not only in the diffraction direction of the diffraction grating to 1st order diffracted light 101a but also in the direction perpendicular to the diffraction direction.  As a result, the stray light 103a is prevented from being made incident on the photodetector and the influence of the stray light caused by the reflection of the plate 4 is eliminated.

Title: Manufacture of chalcopyrite structure semiconductor thin film
Inventor: TERAUCHI MASAHARU
IPC: C23C14/06
Filed: 1994-06-01
Abstract: PURPOSE:To enable production of a chalcopyrite structure semiconductor thin film with desired electrical characteristics by depositing a thin film in a substrate using a chalcopyrite compound semiconductor itself as a target by using sputtering at a substrate temperature whereat a constituent element does not vaporize again. CONSTITUTION:When a sputtering method is used as a method for depositing a thin film 2, a composition of a vaporizing element approximately coincides with a composition of a target. Since a substrate temperature during deposition is low, an element attained a substrate 1 does not vaporize again and neither is crystallized to a chalcopyrite structure. Therefore, the deposited thin film 2 is an amorphous or fine crystalline thin film wherein composition of a constituent element coincides with composition of a chalcopyrite compound semiconductor which is a target. A desired chalcogen thin film 3 is deposited on the thin film 2 and crystallized by thermal treatment, and a chalcopyrite structure semiconductor thin film is formed.

A laser light projector 1 and a photodetector for the light reflected from the surface of the upper roll RL1 are installed to the housing H right above the upper roll RL1. The upper roll RL1is displaced in the tension direction by overcoming the force of the materials EL if the material M go be rolled between the adjacent stands has the tension. Such displacement is detected from the position where the reflected laser light is received. The tension between the stands is easily and inexpensively detected by the slight modification of the installed rolling mill.

Moreover, in the case of processing the video signal, the video signal processed by a picture display means 12 is displayed. Since the video signal after processing is confirmed on the pattern of the display means and corrected in real time, the still picture printed out after the processing is checked to eliminate the need for a trouble repeating try and error thereby correcting the video signal. Thus, the still picture with high quality is obtained in one operation without useless print.

Title: Air intake device for internal combustion engine
Inventor: YAMADA TOSHIO
IPC: F02B29/08
Filed: 1991-05-27
Abstract: PURPOSE:To improve combustion to reduce the fluctuation in torque, and reduce pumping loss. CONSTITUTION:At the time of part load, an opening and closing valve 26 is fully opened to introduce a great amount of intake-air from an intake-air heating pipe 24, and thus heat the intake-air. The amount of intake-air is controlled by controlling the valve-closing timing of intake-air control valves 19-22. The lower the temperature of intake-air, the later the valve-closing timing of the intake-air control valves 19-22 is set to prevent the drop in temperature of air-fuel mixture to reduce the fluctuation in torque. At this time, a linkless- throttle valve 23 is throttled so that the amount of intake-air is not increased, and thus the pressure in a surge tank 13 can be reduced.
