Filed: 1982-08-23
Abstract: PURPOSE:To obtain the semiconductor device, in which an excellent epitaxial growth layer is acquired, by thermally treating a substrate at a specific temperature in an oxidizing atmosphere and removing an oxide film formed to the surface of the substrate. CONSTITUTION:A wafer is divided into halves and one of them is thermally treated in an oxygen atmosphere for 1.5hr at 1,000 deg.C or more such as 1,100 deg.C, the oxide film formed is removed by hydrofluoric acid, the wafer is entered in an epitaxial growth oven, and a silicon epitaxial layer is grown in 5mum. The other is entered in the epitaxial growth oven as it is forcomparison, and an epitaxial layer is grown only by the same film thickness. Both layers are grown in an epitaxial manner through a normal method in which the surface layer of the substrate in 0.5mum is removed in a mixed gas atmosphere of HCl+H2 at 1,200 deg.C and the layer is grown at a growth rate of 1mum/min at 1,200 deg.C by using a mixed gas of SiCl4+ H2. Stacking faults are decreased and defects induced on epitaxial growth can also be reduced in the growth layer forme a in this manner. Defects difficult to be observed or defects, etc. observed as pits of shallow bottoms, shallow pits, can also be reduced remarkably.

Title: Variable filter circuit
Inventor: AMASAWA KIYOSHI
IPC: H03H11/12
Filed: 1979-11-12
Abstract: PURPOSE:To form a filter variable in cut-off frequency by feeding the output of an amplifier, applied with an input signal, back to the input side of the amplifier by way of an electronic volume and filter circuit; CONSTITUTION:Input signal ei is applied to the positive terminal of amplifier 1, whose output is connected to filter circuit 3 via electronic sound volume 2. Filter circuit 3 provides feedback to the negative terminal of amplifier 1 by way of buffer circuit 4 and resistances R2 and R3 and is in the shape of a closed loop on the whole. When the frequency of input signal ei is lower than cut-off frequency f0 of filter circuit 3, capacitor C causes no loss and the loop gain is decreased. As the loss of electronic sound volume 2 is increased, the loop gain lessens and the cut-off frequency decreases like fC1, fC2, fC3-.

Title: Recovery of oxygen from external combustion energy generated gas turbine device
Inventor: MAIKERU SHII KAN CHIEN
IPC: B01D53/32
Filed: 1991-05-21
Abstract: PURPOSE: To extract high-purity oxygen from an externally fired energy generating gas turbine which uses a high temperature solid electrolytic membrane.  
     CONSTITUTION: A low of thermally compressed air from a compressor which generates energy by expansion through a turbine expander is passed first across a supply side for a solid electrolytic membrane having selectivity of permeation of oxygen more than other components of the air. At this time, while a positive oxygen ion potential is held on the membrane to separate the oxygen from the air flow, the remaining air after the oxygen is removed from the permeate side of the membrane is expanded through the turbine expander to generate energy. The air flow is sent to a low-pressure firing device, and thermal combustion outflow gas is usable for further heating of thermocompression process air and also sent to a steam generating device thereafter to recover additional energy, so that the high-purity oxygen can be recovered with low capital cost and low energy consumption.

Title: Checking of abnormal value for chromatograph
Inventor: INOMATA TAMOTSU
IPC: B01D15/08
Filed: 1984-07-16
Abstract: PURPOSE:To enable a chromatogram display of analysis data only when an abnormal value is generated, by setting the range of abnormal value beforehand to display a chromatogram showing an analysis value continuously only when the analysis value is within this range. CONSTITUTION:The range of abnormal value of analysis data is set on a CPU3 by operation of a keyboard 1. Then, a sample is analyzed chromatographically with an analyzer 2 and the results are sent to the CPU3 as output signal from the analyzer 2. The output signal undergoes a specified arithmetic processing such as comparison with said abnormal value by the CPU3. A printer 4 prints out the analysis data in a chromatogram display as sent out from the CPU3. With such an arrangement, by observing a chromatogram showing the analysis data in case abnormality occurs, it can be distinguished easily whether the abnormality is caused by factors of an object itself to be measured or interferring components. When there is no abnormality in the analysis data, only numerical display of the analysis data is given and thus, even in the processing of samples in large numbers, this minimizes the consumption of paper for the printer while making data easy to visual observation.
