Title: Infrared-ray analyzer
Inventor: AOKI JUNJI
IPC: G01N21/35
Filed: 1993-01-13
Abstract: PURPOSE:To make it possible to reduce the effect of interference gas with a simple constitution by sealing the interference gas or gas in the approximately same absorbing spectrum band as the absorbing spectrum band of the interference gas in a solid-type infrared-ray detector. CONSTITUTION:The infrared rays emitted from an infrared-ray source 1 having a reflector 2 are converged into luminous flux M. Along the luminous flux M, a measuring cell 3, a band pass filter 4, which passes the infrared rays in a specified absorbing band only for component gas to be measured, and a pyro-sensor 5, wherein interference gas is sealed, are sequentially arranged in the emitting direction of the infrared rays. Gas to be measures S comprising various kinds of components incorporating the interference gas flows through the cell 3. The infrared rays, which have passed through the filter 4 enter into the sensor 5. The energy corresponding to the energy spectrum of the interference gas in the gas to be measured S is absorbed and removed from the infrared rays. The energy is converted into the electric output signal in an electric circuit 10, and the signal is indicated on an indicating device 11.

IPC: G06K9/62
Filed: 1978-02-27
Abstract: PURPOSE: To simplify the circuit constitution as well as to increase the accuracy by using the matching pattern of both the thin and thick patterns as the reference pattern for decision of the quality.  
     CONSTITUTION: The thin pattern (a) and thick pattern (b) are memorized previously in the computer, and mark X and its periphery Y are scanned via the TV camera system. Then the video signals are fed into the computer to secure the matching between patterns (a) and (b). First, the matching is secured between pattern (a) and mark X to be decided to identify the gradation of mark X caused by the brightness levels at the area of mark X as well as the mark break. While the matching is obtained between pattern (b) and mark X to identify the excessive thinness or thickness of the line, the blur and the ink splash at the periphery of  mark X. Thus, nondefective patterns (a) and (b) are decided as good products  finally.

Abstract: PURPOSE: To simplify a structure by separating a cooling circuit for purifying laser gas from a laser and operating it independently of the laser by a shunt line. CONSTITUTION: The discharge space of the laser 10 is connected to the cooling circuit. In the operation state of the laser, when a valve 14 is opened, a pump 16 carries gas through a gas storage 18 to a heat exchanger 20 and hot contaminated laser gas which arrives from the laser 10 is pre-cooled by a cooling trap 22 in the heat exchanger 20. Then, a cooling source 24 containing liquid nitrogen cools contaminants in the laser gas so as to be frozen on the wall of the cooling trap 22. Then, the purified laser gas is returned through the valve 28 to the laser 10. At the time of stopping the laser 10, when both valves 14 and 28 are closed and the valve 36 of a branching line 38 is opened, the pump 16 is operated by a closed circuit to which constituting elements 16, 18, 20, 22 and 26 are added.
