Filed: 1987-08-27
Abstract: PURPOSE:To reduce positive fixed charge amount generated in an oxide film when an ionizing radioactive ray is incident by isolating elements by a polycrystalline silicon enclosed with a thin oxide film. CONSTITUTION:A thin oxide film 2 is formed on a P-type silicon substrate or a P-type well 1, and a polycrystalline silicon 3 is formed thereon. The silicon 3 employs that doped with phosphorus. Then, the isolating width is patterned, and only the silicon 3 is enclosed with a thin oxide film 4. Thereafter, an active region 5 made of a silicon epitaxial layer is formed by selectively epitaxial growth. Subsequently, an N<+> type diffused layer 8, a gate oxide film 6 and a gate electrode 7 are formed on the region 5. Thus, elements are isolated by the polycrystalline silicon enclosed with the film 4 to remarkably reduce the positive fixed charge amount generated at the film 4 as compared with a conventional case.

Abstract: PURPOSE:To shorten the period of construction as well as reduce the cost of construction by a method in which a structure consisting of side walls and slabs which are constructed on the ground's surface is sunk while excavating the ground, and concrete is placed to the inner bottom of the structure to construct the bottom. CONSTITUTION:An auger excavator C connected with a vacuum hose D for discharging soil is set on a place where excavation is to be made, and a structure B consisting of side walls 1 and slabs 2 is constructed on the ground's surface. A soil pressure-receiving steel material E is attached to the inside between the walls of the structure B, and the ground is excavated by the excavator C to settle the structure B down as the excavation proceeds. The excavator C and the hose D are removed after the preset excavation is ended, the bottom 4 of the structure B is constructed, and the steel material E is removed to form an underground structure A. Since the needs for temporary work for pit excavation can be eliminated, the period of construction can be shortened.

Title: Circuit for eliminating carrier chrominance signal
Inventor: YAMASHITA SHIGEO
IPC: H04N9/78
Filed: 1982-12-06
Abstract: PURPOSE:To reduce the effect of a luminance signal component on a frequency band of a carrier chrominance signal by designing the circuit that only a PAL color video signal is applied and the PAL color video signal not including the carrier chrominance signal is outputted as it is, when no chrominance carrier signal exists. CONSTITUTION:When no color difference signal is included in the PAL color video signal, that is, the signal level of the carrier chrominance signal is zero, a color difference signal detecting signal is annihilated, an analog switch 11 is opened, an output of a two-multiplication circuit 6 is not applied to a multiplier circuit 7 and no signal is outputted from the multilier circuit 7, resulting that only the PAL color video signal is applied to an adder circuit 2 to which the output of the multiplier circuit 7 is applied via a low pass filter 8. Thus, when the PAL color video signal not including the carrier chrominance signal is applied to a band pass filter 1 and the adder circuit 2, the supplied PAL color video signal is outputted from the adder circuit 2 as it is.
