Title: Detecting device for linearity of board side edge
Inventor: SHODA SHIN
IPC: G01B21/30
Filed: 1984-08-06
Abstract: PURPOSE:To detect the linearity of the side edge of a board by conveying the board and detecting its conveyance-directional front end and rear end at the same time, determining a virtual slanting straight line to the conveyance direction, and comparing a measurement point of every time with the virtual slanting straight line. CONSTITUTION:The board 14 for building material is conveyed by a roller type conveyor 11 as shown by an arrow A. At this time, image sensors 25 and 26 detect the conveyance-directional front end 18 and rear end 19 of the board side edge at the same time and a computing element 20 calculates the inclination of the board straight line to the conveyance direction while the board is considered to have linearity virtually. The conveyance-directional distance is divided at every specific time and the measurement point of the side edge of the board 14 is detected by a light emitting element 15 and a photodetecting element 16. Then, the distance between the measurement point and a virtual point on the virtual straight line is calculated by the computing element 20 to detect the linearity. Therefore even when the board is placed slanting to the conveyance direction, the linearity of the board side edge is detected precisely.

Title: Cleaning method of silicon substrate surface and equipment therefor
Inventor: HIROSE FUMIHIKO
IPC: H01L21/304
Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To enable simultaneous treatment of a plurality of sheets, instead of leaf-treatment, wherein sheets are treated one by one, improve throughput, and realize cost reduction, by arranging a silicon substrate in a vacuum vessel, exposing the substrate to hydrogenated germanium gas and heating the substrate at the same time. SOLUTION: A silicon substrate 3 is heated at 800 deg.C, and at the same time, germane gas is introduced into a vacuum vessel 1 through a flow rate adjusting valve 4. During 20 minutes when firstly germane is introduced, germane is thermally decomposed on the surface of the silicon substrate 3, and germanium is deposited on the surface. Deposited germanium reacts with SiO2 as a silicon oxide film on the substrate surface, and oxygen atoms O in the silicon oxide film evaporate as GeO. During the treatment, the silicon oxide film on the surface is eliminated completely, and a small amount of germanium is left on the surface. This germanium is eliminated by heating a steel plate in a vacuum for 20 minutes.

Inventor: URINO YUTAKA
IPC: G02B5/30
Filed: 1988-06-29
Abstract: PURPOSE:To obtain an inexpensive polarizer which has low insertion loss and a high extinction ratio by using a dielectric film which has a refractive index close to that of a crystal substrate and forming a reflection preventive film of uniform thickness on the entire surface of its grating.

Abstract: PURPOSE: To easily control the BOD value of waste water, by preparatively finding out the relation of a BOD value with a turbidity of waste water, and detecting the BOD value by measuring a turbidity of the waste water.  
     CONSTITUTION: A BOD value of waste water flowing in a waste water pit 8 is detected by measuring its turbidity with a turbidometer 9. When the BOD value is lower than a self-imposed control level, the waste water is fed to a reservoir 10, adjusted in its pH value and discharged. When the BOD value is higher than the self-imporsed control level, the waste water is fed to a reservoir 11 by pump or valve means 13, adjusted in its pH there by pH control means 15, and carried to a biological waste water decontamination apparatus 18 by a flow rate controlling pump or valve 17 while measuring its BOD value by a turbidometer 16. In the apparatus 18, the waste water is treated to attain a proper BOD value. The BOD value of the biologically treated waste water is measured by a turbidometer 19. If the BOD value is lower than the control level, the waste water is discharged. If the BOD value is higher than the control level, the discharge is stopped and the waste water is subjected to a further biological treatment.

Title: Paper feeder for copier etc
Inventor: NAKAJIYOU YOSHIO
IPC: B41L21/00
Filed: 1980-11-26
Abstract: PURPOSE: To prevent any paper jam as well as to improve the traveling performance of paper, by maintaining a constant load applied on the drive source for vertical movement of a paper tray, regardless of the amount of paper on the tray.  
     CONSTITUTION: A load correcting device 6 consisting of a tension spring 7, a pulley 8 and a wire 9 is installed on the bottom surface of a paper tray 3 in the main unit 1. As the amount of paper 4 decreases as paper supply progresses, the tray 3 goes up, being driven by a drive source (omitted in the figure.), thereby forcing the paper 4 on the top end to make an overrun (h) of climb from the defined level of the transportation surface A owing to the inertia caused by lifting motion of the tray 3 and paper 4. However, the distance of overrun (h) for a reduced quantity of paper 4 is kept almost equal to that for the original large quantity of paper 4 because the load applied on the drive source can be maintained constant through the load correcting device 6, and thus a stabilized traveling performance of paper can be provided.
