Patent JP-S58124243-A (JP)
Title: Manufacture of semiconductor device
Inventor: MATSUMURA HOMARE
IPC: H01L27/12
Filed: 1982-01-21
Abstract: PURPOSE:To improve the circuit characteristics of a semiconductor device by forming the second oxidized film which reaches an insulating substrate on the region exposed with silicon pattern and the third oxidized film which reaches at least the first oxidized film and does not reach the substrate, thereby eliminating the floating state of the substrate while corresponding to the trend to the decrease in the thickness of a silicon layer. CONSTITUTION:Though the thickness of a silicon layer formed on a sapphire substrate 31 is extremely thin, e.g., 4,000Angstrom , a p<+> type impurity layer 40 having sufficient thickness to become wirings between the third oxidized film 39 and the substrate 31 can remain. Accordingly, a semiconductor base 45 between a source region 43 and a drain region 44 can be externally led through the layer 40 and the base leading region 46, and the potential can be fixed. Thus, the circuit characteristics can be improved. Further, since the third oxidized film 39 on the layer 40 to become wirings is thick, the floating capacity between the wirings and the silicon layer can be reduced, and the circuit characteristics such as propagation velocity and the like does not deteriorate.

Abstract: PURPOSE:To facilitate the constitution made into IC on devices performing an ATF control by detecting the amplitude in the manner of performing an A/D conversion for a reproduced signal by a sampling signal having the common multiple frequency of pilot signal frequencies for the detection. CONSTITUTION:The output of a clock generation means 301 is frequency-divided by a sampling clock generation means 302, and a sampling clock (k) having the common multiple of two frequencies of the pilot signal is prepared. The reproduced signal (i) is sampled with the clock (k) by a sampling means 303 after passing through a low-pass filter 304 and subjected to A/D conversion. As to the output, the amplitudes of the pilot signal are detected with the clock (k) by two amplitude detecting circuits 401a, 401b, and the tracking error signal (k) is outputted by a difference circuit 600 from the difference between both outputs. The positional relation between an objective track and a head is thereby controlled. By this constitution, the device is easily to be made into IC without being affected by the variance of elements to be used, and the constitution of the amplitude detecting circuits are also simplified.

Title: Waste water treatment
Inventor: NIWA CHIAKI
IPC: C02F3/06
Filed: 1981-01-23
Abstract: PURPOSE: To avoid generating dead spaces in the interior of a packing material and treat organic waste water efficiently by a method wherein rugged sheet formed packing materials having different specific surface areas are alternately stacked, and waste water is passed in parallel to the stacking surface.  
     CONSTITUTION: The rugged sheet formed packing materials differing from each other in specific surface area by a factor of not less than 30% are alternately stacked with a stack spacing of not less than 8mm, and organic waste water is biologically treated by passing it in parallel to the stacking surface. Since the packing material having a smaller specific surface area and the packing material having a larger specific surface area are stacked alternately, two kinds (thinner and thicker) of biological slimes are formed correspondingly. In addition, since the flow velocity of waste water is varied, there arise variations also in the rate of diffusion of pollutants (contained in waste water) onto the surfaces of the biological slimes, as well as the rate of permeation of the contaminants into the slimes, etc. Accordingly, various kinds of organic matter and decomposition intermediate products in the waste water can be decomposed efficiently.

Title: Reed-valve type secondary-air supplying system for internal combustion engine
Inventor: YAMASHITA RIYUUICHI
IPC: F01N3/34
Filed: 1979-01-29
Abstract: PURPOSE: To prevent reduction in the flow rate of secondary air based on the reason of the fact that operation of reed value is affected by pressure wave acted on the upstream side of reed valve, by providing a reed valve at a portion of secondary-air supplying passage, and forming an expansion chamber adjacently of said reed valve on the upstream side of the same.  
     CONSTITUTION: Pulsation is caused in exhaust passage 21 by intermittent discharging of exhaust gas ans pressure wave produced by the pulsation is transmitted to reed valve 27 via valve 27 via secondary-air supplying passage 28. When the pressure wave is in its negative-pressure mode, reed valve 27 is opened so that air is passed through air cleaner 18, secondary-air supplying passage 32, expansion chamber 31, reed valve 27 and secondary-air supplying passage 28 and then introduced into exhaust passage 21. Here, pressure wave transmitted to the upstream side of reed valve 27 is attenuated considerably in expansion chamber 31 since it is disposed adjacently of the reed valve 27. Pressure wave is then reflected by element 33 and attenuated again in expansion chamber 31. Therefore, reed valve 27 is not affected by pressure wave acted from the upstream side thereof, so that it is operated in a required manner.
