Title: Multistage device and method for continuous waste water filtration
Inventor: ETAN SHARRILL
IPC: B01D36/04
Filed: 1998-03-06
Abstract: PROBLEM TO BE SOLVED: To provide a device and a method for purifying waste water or drinking water, which is continuously operated to prevent the clogging of a filter. SOLUTION: A coagulant 20 is added and mixed to waste water 1b contg. free solid content in a first tank 12, the formed mixture is sent to a second tank 30 having an inclined bottom part, the relatively large coagulated solid content 34 is precipitated in the second tank 30 and the precipitated solid content 34 is periodically discharged from a port 36 which can be opened and closed and is installed in the lower part of the second tank 30. Somewhat clear water crosses an upper weir 40 installed in the second tank 30 and is fed to a perforated belt 44 in a non-tension state to be continuously operated. The pores of this belt 44 are sized so that they hold the fine coagulated solid content 60 and on the other hand, the transparent water can pass through them.  Moreover, the speed of the belt 44 is controlled so as to form lumps of 1 mm or less thickness of the fine coagulated solid content on the surface 46 of the belt 44 and to improve the filter capacity of the belt.

These Q and R enter in a fraction processing circuit 6 and the correction point number for each skip drawing step is determined. The result is written in a correction memory 7 by each scanning step. These correction point numbes is read by each skip drawing step and the exposure position is corrected.

Title: Detecting method of surface defect of thin piece
Inventor: FUJISAWA KAZUO
IPC: G01N29/04
Filed: 1984-03-22
Abstract: PURPOSE:To detect accurately a surface defect by making a converged ultrasonic wave beam on a thin piece like a silicon wafer above a critical angle, and detecting scattered light reflected at the defect position. CONSTITUTION:The converged ultrasonic wave beam from an ultrasonic probe 1 is made incident on the thin piece such as the silicon wafer 2 after an etching process above the critical angle and focused on the silicon wafer 2. When there is no defect on the surface of the silicon wafer 2 (a), the wave is reflected specularly and no reflected wave returns to the probe 1. When there is a defect (b), the incident ultrasonic wave beam is scattered by the defect 3 and its reflected wave returns to the probe 1. Further, the silicon wafer 2 is rotated to move the probe 1 from the end part to the center part and flaw detection is carried out over the entire surface of the silicon wafer 2. Thus, the ultrasonic wave beam is made incident above the critical angle and the defect is detected according to whether there is a diffuse reflected wave, so the defect of the thin piece is detected with high precision.

Title: Infrared ray detector
Inventor: OSHIMA KAZUYUKI
IPC: G01J1/02
Filed: 1987-03-13
Abstract: PURPOSE:To connect electrodes and conductive heat insulating patterns and adhere and fix an IR detecting element onto a supporting substrate by using graphite or carbon and glass and welding glass by high-temp. calcination. CONSTITUTION:The electrodes 3A, 3B of an IR detecting element 1 and the conductive heat insulating patterns 51, 52 and heat insulating pattern 6 of the insulating supporting substrate 2 are formed by screen-printing of the paste consisting of the graphite or carbon as well as the glass and binder. The extension part 33 of the electrode 3A and the leading out part 3'2 of the electrode 3B as well as the patterns 52, 51, the adhered part 4 and the pattern 6 of the element 1 are adhered and fixed by the fusion of the glass in the paste when the element 1 is superposed on the supporting substrate 2 and is calcined at a high temp. Since graphite or the carbon and the glass do not completely wet each other at the time of the calcination, the conductive heat insulating patterns by this constitution contain many small pores in the inside and since there is a space between the element and the substrate, the heat hardly escapes. The element is hardly exfoliatable as the element is directly adhered to the substrate.
