Title: Gate monitor
Inventor: KIKUCHI KATSUKO
IPC: G01T1/00
Filed: 1992-01-23
Abstract: PURPOSE:To enable measurement without making a person to be measured feel a pressure by a method wherein a head detector is connected to the body of the apparatus free to move in an arbitary direction and placed on a head of an object to be inspected covering the front of the head to shorten the time of measuring for the presence of radiation. CONSTITUTION:A person to be measured entering into a gate through an entrance door 17 puts a head detector 22 on his head by himself to be supported with his shoulder or head. Then, he inserts his hand into hand detectors 15a and 15b and a front cover of the body of a helmet is closed to start a mesurement. Here, time required until the measurement is started is to the putting of the detector 22 from the entry into a room in substance. For example, as compared with when a radiation detector is lowered automatically, the time is reduced significantly. The putting of the detector 22 on the head of person can reduce uneaseness of the person to be measured. Detection signals from detectors of parts containing the detector 22 are sent to a measuring circuit to measure the presence of a radiation substance. After the end of the measurement, the detector 22 is removed from the head to be placed at a specified location and the person to be measured leaves the room through an exit door 19.

Filed: 1982-01-27
Abstract: PURPOSE:To constantly maintain combustion in the best condition regardless of the temperature of combustion air by constantly maintaining the flow speed of combustion air at a constant value by making variable the sectional area of the annular space through which combustion air passes. CONSTITUTION:Metal bellows 16 forming a tightly closed space A in which air is tightly sealed are used as air temperature detection means, and flow-out area adjusting means is constituted by a buffle plate 15 and a burner slot 9. Upon starting the engine, the temperature of combustion air is low due to the shortage in preheating, and therefore the volume of air in the tightly closed space A within the bellows 16 is small. The area of annular space 11 formed between the burner slot 9 and the flange 15b becomes minimum. Further, when the driving of the engine is continued and the temperaure of combustion air to be preheated increases the temperature of air in the tightly closed psace A within the bellows 16 also increases, and the volume expands. Therefore, the flange 15b of the baffle plate 15 moves in the direction of the combustion chamber 1, and the area of the annular space 11 where combustion air passes in opposit ion to the  enlarged part 9a of the burner slot 9.

Title: Phase lock detecting circuit
Inventor: MAKIMOTO MITSUO
IPC: H03L7/08
Filed: 1982-01-26
Abstract: PURPOSE:To perform phase lock detection securely by adding a function for frequency decision as well as level decision. CONSTITUTION:A digital comparator 32 performs a digital comparison between a frequency at a modulation terminal 7 and the frequency of the output signal of an AC amplifier 31 which is counted by a counter to generate an H-level output only when the both coincide with each other, or an L-level output when not. An AND circuit 36 has a level H only when the control voltage of a voltage-controlled oscillator VCO7' contains no AC component and a DC component within some level range. An OR circuit 37 has a level H when either of the comparator 32 and circuit 36 generates the H-level output. Therefore, only when the modulator is locked, an H-level signal appears at a terminal 38, so this signal is utilized to obtain a lock signal easily.

Abstract: PURPOSE:To grow the good-quality insulating film and etc. at low temperature with the good mass production property by providing a main reaction chamber subjected to light irradiation, a plasma generating chamber connected to said reaction chamber and further arranging a plasma leading electrode on the side of main reaction chamber so as to introduce a part of the material gas for vapor growth and a gas of the rest into the main reaction chamber and the plasma generating chamber respectively. CONSTITUTION:In a main reaction chamber 11, an insulating film of SiO2, SiN and etc. grows at low temperature by a photochemical reaction and after completion of the growth, an etching gas such as CF4 is introduced into a plasma chamber 12. Then a plasma is generated and a plasma or an excitation radical of the etching gas is led to the main reaction chamber 1 by applying a bias voltage to a plasma leading electrode 14. The film deposited on the wall of the main reaction chamber is subjected to dry etching thereby enabling the repeated growth. Because the main reaction chamber 11 subjected to light irradiation and the plasma generating chamber 12 are arranged almost separately, a light excitation reaction is caused effectively and the plasma generating conditions can be made optimum.
