Title: Suction type ozone gas detector
Inventor: TAJIMA MASAAKI
IPC: G01N27/416
Filed: 1990-11-26
Abstract: PURPOSE:To enable detection of concentration to a high degree and also to facilitate zero gas calibration by providing a decomposition heater in a flow passage of a sample gas. CONSTITUTION:A suction pump being used, a sample gas is made to flow at a prescribed flow velocity through a chamber 1 by a detection gas introduction pipe 4, and a decomposition heater 5 of an alumina base having a pattern of platinum or the like is provided in front of a flow passage.

IPC: H04N19/60
Filed: 1991-12-09
Abstract: PURPOSE:To provide a quantizer which hardly causes a non-coding block for a block possibly causing picture quality deterioration if it becomes the non- coding block. CONSTITUTION:A constant (a) smaller than the unity is set to a constant number setting device 3, and the constant (a) are multiplied by a multiplier 4 at the same quantizing width as that of the quantizer 5, the product is quantized by a quantizer 6.

IPC: H01L21/205
Filed: 1989-12-14
Abstract: PURPOSE:To prevent gas or unreacted gas from being deposited in an exhaust system pipe and a vacuum device after reaction so as to prevent an inner diameter of the pipe from being thin and a vacuum degree from being influenced by maintaining the exhaust system pipe for exhausting from a reaction chamber through the vacuum device at a Tammann temperature or higher of a substance deposited or expected to be deposited on the pipe. CONSTITUTION:A pipe heater 11 for maintaining a pipe 7, from the outlet of a reaction chamber 3 through a vacuum pump 9 to exhaustion at a Tammann temperature (2/3 of a melting point of a substance in absolute temperature) or higher of a substance, expected to precipitate on the pipe wall and cause clogging, is provided. That is, since a gas exhaust pipe 7 from a reaction tube 3 is maintained at a Tammann temperature or higher of the expected substance by the heater, 11, there is no difference in temperature rapidly caused in exhausted gas 8 of the reaction tube so that the substance is not deposited to attach to the inner wall of the gas exhaust tube 7 or it is not deposited to attach to a protecting mesh 10 of a vacuum pump 9. Thus the pump protecting mesh 10 is not clogged so that the inner diameter of the gas exhaust tube 7 does not become thin giving no influence on the degree of vacuum.

Abstract: PURPOSE:To obtain a semiconductor laser where the dispersion of the images in horizontal far view is small by putting the shoulder of a stripe-shaped trench in smooth shape by etching after forming the stripe-shaped trenched but before performing epitaxial growth. CONSTITUTION:The first N-GaAs current block layer 2 is crystal-growth on a P-GaAs substrate 1, and then a stripe consisting of a V-shaped trench is made.
