Abstract: PURPOSE: To simplify the constitution by collating memory information with input data by using a variable resistance element whose resistance value depending upon an applied voltage, current or the both varies unreversibly and a semiconductor active element such as a field effect transistor.  
     CONSTITUTION: To write information "0", input data line D 0  is held at a high voltage and inverted input data line D 0 ' at a low voltage; and a voltage higher than the threshold value when variable resistance element R 11  varies unreversibly from high resistance to low resistance, current or the both are applied to node N 0 . Variable resistance element R 11  varies unreversibly from high resistance to low resistance. To read the information, write/earth voltage line N 0  is held at the earth voltage and collation output line M 0  is disconnected from the earth. By holding variable resistance R 12  at low resistance, information "1" is written in.

Abstract: PURPOSE:To improve the stability in the detection of the position of a metal surface and to improve the accuracy of measurement by setting the upper and lower limits of spaces between the metal surface and a detecting end, and driving the detecting end in accordance with the distances to said upper and lower limits. CONSTITUTION:When the levels of the distance signals between coils 271-273 and a molten metal surface attain the set value of an upper limit, an FF-F1 is set with an intransformer 57a by the contact of a cam 55 with a contact 56a, and the forward runnung contacts of a servocontrol motor driver 39 are closed and a timer TM is triggered. Then, a motor 4 runs forward and the detecting end moves downward. After a prescribed time, the detecting end stops. When the level of the distance signals drops down to the set value of a lower limit, an FF-F2 is set by the contact of the cam 55 with a contact 56b, and the motor 4 is driven backward. The TM is then triggered and the detecting end moves upward. After the preset time, the motor 4 stops. Then, the detecting end is returned to the intermediate of the set values of the upper and lower limits. On the other hand, the distance signals and the position signals are added 60, and the position signal for the metal surface is outputted.

Title: Method for measuring receiving level
Inventor: FUJII TERUYA
IPC: H04B17/00
Filed: 1995-01-10
Abstract: PURPOSE: To accurately find the receiving level of a receiver for radio waves from a mobile measurement vehicle without relying upon the moving speed of the vehicle at the time of measuring the average radio wave receiving level of the receiver when the vehicle moves in a fixed section by transmitting the radio waves from the vehicle while the vehicle moves and receiving the radio waves by means of the receiver fixed to a prescribed position. CONSTITUTION: A mobile measurement vehicle 1 transmits radio waves from a transmitter 101 while the vehicle 1 moves. While the transmitter 101 transmits the radio waves, a controller 104 on the vehicle 1 records the moving distance of the vehicle 1 based on the data from a clock 103 and distance sensor 102. On the receiving side, on the other hand, a receiver 201 receives the radio waves from the transmitter 101. A controller 203 on the receiving side records the receiving level of the receiver 201 at regular time intervals based on the time data from a clock 202. Then the average receiving level of the receiver 201 in a fixed section is found based on the moving distance of the vehicle 1 and receiving level recorded at the regular internals.

Abstract: PURPOSE:To heighten the anti-pressure strength of port parts of flat pipes and to make the thickness of materials thin as well as to enable to keep the refrigerant carrying function, by a method wherein a flange type part is provided at the periphery edge of inserting holes of a distribution pipe or a collecting pipe and is adhered to the distribution pipe or collecting pipe. CONSTITUTION:Liquid phase refrigerant which is sent from a refrigerant supplying pipe 7 to a refrigerant distribution pipe 3, is poured out to a port part B of each flat pipe A for access of refrigerant from a slit 3a for supplying refrigerant which is provided as the distribution pipes 3 at the determined space, and since vaporize expansion is started by absorbing the open air heat, steam pressure is applied to the inner wall surface of the port part B. But, because the width of the port part B is narrowed by the amount flange type parts 12 and 13 are provided to the both side of it, the inner volume of the port is decreased, and the degree of deformation by innerpressure becomes small, accordingly, exfoliation power which effects to the connecting surface d is decreased. Short-circuiting refrigerant flowing between adjacent port parts is not generated, and refrigerant can be equally distributed to each port part, and the heat exchange property can be improved.

Abstract: PROBLEM TO BE SOLVED: To effectively detoxify NF3 gas by introducing a gas containing NF3 gas into a reaction tube packed with a metal powder upwardly from a bottom side and causing a reaction under a heating condition at a specified temperature while the gas is being brought in contact with the metal. SOLUTION: When a gas containing NF3 gas is detoxified, first N2 gas is introduced into a reaction tube 10 while an interior of the reaction tube 10 is heated by a heater 20, and in this state a gas produced by diluting the NF3 gas with the N2 gas is introduced into the reaction tube 10 through a gas introduction pipe 12. Two hours starting from a start of introduction is spent for raising temperature within the reaction tube 10 to 150-500 deg.C. At this moment, the metal powder 11 is circulated and moved by inertia of the introduced gas in the reaction tube 10 and each particle of the metal powder 11 is made to uniformly contact with the gas and is reacted with the NF3 gas. Surfaces of the metal powder 11 are coated with a fluoride film, surface lubrication characteristics are enhanced and powdery state is maintained.

Title: Manufacture of light guide
Inventor: KAEDE KAZUHISA
IPC: G02B6/13
Filed: 1983-01-11
Abstract: PURPOSE:To obtain a light guide which is manufactured easily and has small light guide loss by forming the light guide of fused glass on a substrate by spin coating, and providing at least one glass layer formed by spin coating between the substrate and light guide layer. CONSTITUTION:The fused glass is layered by spin coating on the substrate 11 made of alumina ceramic which does not deform plastically at the fusion temperature of glass to form a buffer layer 13 and the light guide layer 14. In this case, the refractive index of high flint glass used for the light guide layer 14 is higher than that of potash flint glass used for the buffer layer 13, so light incident to the light guide layer 14 is confined therein and propagates inside. Thus, a part of the light guide layer functions as a lens, so even when the surface of a recessed part 12 formed in the substrate 11 by polishing is a little bit uneven, the surface is close to a specular surface at the stage of the formation of the buffer layer 13 by spin coating as far as it is less rough than the thickness of the buffer. Therefore, the light guide loss of the light guide layer 14 is extremely small.
