Title: Signal delay circuit for sensor
Inventor: KASHIWAGI KAZUHITO
IPC: H03K3/3525
Filed: 1986-05-26
Abstract: PURPOSE:To obtain accurate signal delay time by starting the charging of a capacitor after the charging electric charge in the capacitor charged based on a sensor detection signal is discharged surely. CONSTITUTION:In inputting a detection signal from a sensor 1 again at a point of time when a voltage at a point X does not exceed a threshold voltage L of a PUT 3, an output of a comparator 4 goes to an L level,the electric charge in a capacitor C3 is discharged to bring the voltage at the point X to zero V. Then the detection signal descends and the output of the comparator 4 goes to an H level, then the charging of the capacitor C3 is started again. Then the charging of the capacitor C3 is progressed and the voltage at the point X exceeds the voltage L, then the PUT 3 is turned on to bypass the base current of an output transistor (TR) Q3. The TR Q3 is turned off by the bypassing to turn off the output from the signal delay circuit. Thus, the time of signal delay is made accurate.

Title: Failure analyzer
Inventor: ISHIDA MINENORI
IPC: G01R31/26
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To obtain a failure analyzer capable of simply and efficiently analyzing failures by using a character-user interface. SOLUTION: When an operator inputs a start instruction from an input unit 1, a controller 2 checks if the test operation of an IC tester 4 has paused or not upon receipt thereof. If not paused, it does not start a failure information displaying process, but if paused, it reads displaying conditions from test programs of the IC tester 4 and takes in displaying conditions to be inputted by the operator. When the displaying conditions are completed, it reads failure information from the IC tester 4 and displays it. If a change instruction for the displaying conditions is applied, it changes only displaying condition items instructed by the operator and switches the display.

Title: Collimator
Inventor: HAYASHI KENJIROU
IPC: G01T7/00
Filed: 1981-07-31
Abstract: PURPOSE:To prevent scattering beams and improve the signal-to-noise ratio by use of a collimator with two holes. CONSTITUTION:Any strong scattering beam from an area d is not allowed to enter a detector b, intercepted with a collimator somewhere in the course. When positioned in the area of h between g and f in the drawing, the collimator provides an adequate effect. The diameter of holes to be made in the collimator is preferably such that the line joining the analysis point c and the detecting section b won't be disturbed. Therefore, the collimator provided close to the detector b is allowed to make the diameter of the hole larger while that provided close to the analysis point c is allowed to make it smaller. The use of the collimator having such two different holes can improve the signal-to-noise ratio thereby elevating the detection sensitivity and accuracy of an X ray microanalyzer.

Title: Waste water treating method
Inventor: HAYAKAWA NOBORU
IPC: C02F1/52
Filed: 1978-10-04
Abstract: PURPOSE: To denitrify and dephosphorize efficiently without requiring pH adjustment, by denitrifying the waste water containing nitrogen in the form of nitric acid in the presence of Ca 2+ .  
     CONSTITUTION: Waste water containing nitrogen in the form of nitric acid, such as NO 2   -  and NO 3   - , is treated in a nitration tank, and is, with Ca 2+  such as Ca(OH) 2  being added, sent into a denitrification tank. This Ca 2+  ion is bonded with PO 4   3-  when the waste water reaches the biological film in the denitrification tank to produce water-insoluble Ca 5 OH(PO 4 ) 3 , which settles on the biological film. In this method, both phosphorus and nitrogen may be removed simultaneously without requiring equipment for dephosphorization alone or pH adjustment for fixing phosphorus. Besides, the Ca 2+  source may be added to the nitration tank. In such a case, since pH of waste water is low, Ca 2+  does not react with phosphorus, and phosphorus is made insoluble after the waste water is moved to the denitrification tank.
