Title: Method and device for liquefying super critical gas
IPC: F25J1/00
Filed: 1992-03-30
Abstract: PURPOSE:To minimize the number of air separators adopted for a liquefier as much as possible and provide an economical device without degrading liquefaction efficiency by diverging a part of low temperature super critical gas before the introduction of a cooling process or after the cooling and isoentropically expanding the gas so as to use a cooling source for the cooling process. CONSTITUTION:A low temperature critical gas diverged to a pipeline 6 is isoentropically expanded and turned into a fluid in a vapor-liquid mixed state by a pressure reducing valve 23. This mixed fluid is consecutively introduced into a second heat exchanger 12 and a first heat exchanger 11 as a return fluid, thereby serving as a cooling source for the super critical gas introduced from a pipeline 1. The low temperature critical gas, which is introduced into a third heat exchanger 13 from a pipeline 5, further cooled with the return gas by way of the pressure reducing valve 23 and output to a pipeline 7, is isoentropically expanded with a pressure reducing valve 24, liquefied and derived. This construction makes it possible to minimize the number of air separators used for a liquefier as much as possible, thereby producing an economical facility.

Abstract: PURPOSE:To enable measuring of other sample which can be measured in a short time while a measurement is made on a sample which it takes a long time to measure, by a method wherein a CW method measurement is conducted through suspending of a measurement by a FT method in the middle of a measurement made by the FT method. CONSTITUTION:If, in the middle of a measurement made by a FT method, a sample, which can be measured in a short time, is needed to be measured, a measurement by the FT method is temporarily supended, and data obtained so far are held in a memory 12. A sample in a detector 2 is then exchanged, and with switches 4 and 9 changed over, a measurement is made by a CW method. If the measurement by the CW method is completed, the switches 4 and 9 are changed over again, an simultaneously, the data, held by the memory 12, are restored back to set it again to a state under which the measurement is done by the FT method. This permits the measurement of other sample, which can be measured in a short time, while a measurement is being made on a sample which it takes a long time to measure.

Abstract: PURPOSE:To increase the data transfer speed and the reprocessing speed when an error occurs by providing a clock generator for clocks to be supplied to each part and a clock monitor means at a primary data processing part and monitoring the clock state sent from the primary data processing part at the secondary data processing part. CONSTITUTION:If a data error is detected at a secondary data processing part 12, a CPU15 holds an error signal 39 at level H for a prescribed period of time. Thus the clocks transmitted via a clock transmission line 42 are interrupted while the signal 39 is kept at H. Then a timer 27 of a primary processing part 11 counts up the time to produce an interruption signal 44. Then a CPU14 starts the interruption processing with the signal 44 and prepares for retransmission of data of each prescribed unit which is transferred imediately before the start of said interruption processing. When a data error is detected at the part 11, a timer 33 of the part 12 counts up the time. Then an interruption is applied to the CPU15 by an interruption signal 45. In this case, the data is transmitted again from the part 12.

Abstract: PURPOSE:To prevent a malfunction of a non-selection switch MISFET due to a negative voltage noise, by providing a clamping MISFET between a input terminal side of a switch MISFET and the ground. CONSTITUTION:A multiplexer consists of plural switches MISFET and selects one of plural analog input signals. Then a control signal is applied to a switch MISFET1 among those of the multiplexer via a control circuit 2 and an inverter 3. Thus the FET1 is turned on, and an analog signal is supplied to an A/D converter 4 to be converted into a digital signal. An input voltage clamping MISFET5 is provided with connection of a diode between the input terminal side of the FET1 and the earth. The threshold voltage of the MISFET5 is set smaller than that of the FET1. Thereafter a current flows to the FET5 when the negative voltage noise is applied to the input side while the FET1 is kept off. Then the FET5 is clamped with the input voltage to avoid an ON operation of the FET1 due to the negative voltage noise.

Abstract: PURPOSE: To set the position possible to always pick appropriate information even though the arc, the jig, etc., cause variation, when the welding condition is monitored and controlled by the monitoring television camera, by constituting so as to  automatically select the video picking position.  
     CONSTITUTION: The welding condition is monitored by television camera 2, and the picking position signal being decided by the picking position judging circuit 7 is sent  to the video processor 8. The scanning line for this position and neighborhood is  taken in and is processed, and the signal necessary for the position and the welding  control is produced. Besides, at the position diaplay generating and synthesizing circuit, the video signal of television camera 2 is synthesized with the line to display  the picking position, and the video is displayed on the monitor 10 so as to clear the  position of the picking signal. Thus, the selection of the video picking line is automatically executed; hereby, even though the welding point is shifted by the fluctuation of the arc generating position, the video picking line is automatically decided,  so that the operator is not required to always watch the picture, and the labor is  saved, the welding is stabilized, and the weld defects are prevented.

Title: Forming method for self-alignment multilayer wire

IPC: H01L21/3065
Filed: 1980-06-06
Abstract: PURPOSE:To enhance the reliability of a microminiature multilayer wire by burying a metal or an insulator by a bias sputtering method in the recesses of a substrate, thereby suppressing the disconnection and the shortcircuitting of the wire. CONSTITUTION:An oxidized film 42 is formed on a silicon substrate 41, a photo resist is patterned on a metal 43 to become a wire formed by sputtering on the entire surface of the substrate, and with the photo resist thus patterned as a mask the metal 43 is patterned. A bias sputtering is performed thereon to equalize the surface of the metal 43 to the surface of an SiO2 film 45, and the exposed photo resist is isolated by etching. Thus, the SiO2 film can be so buried between metallic wires in a self-aligning manner that the surfaces may approximately coincide with one another. When these steps are repeated, a multilayer wire can be formed.
