Abstract: PURPOSE:To make the size of a device smaller by a method wherein an insulat ing region, extending from the element region circumference into a semiconduc tor substrate, and a channel stopper region, expanding in contact with the insulating region from the semiconductor substrate side and nearly covering the element region, are provided. CONSTITUTION:An insulating region 24 and channel stopper regions 13, 16 extend from the side of a semiconductor substrate 11 to cover field-effect transistor element regions 36, 37, 41, 17, 45, 46, 47, 14, and no wells are used. With the channel stopper regions 13, 16 expanding in contact with the insulating region 24, not a very high precision is required between the two channel stopper regions 13, 16 in the process of their forming, and less tolerance is required in the process of positioning. With the element regions 36, 37, 41, 17, 45, 46, 47, 14 being covered from the side of the substrate 11 by the insulating regions 24 and channel stopper regions 13, 16, isolation between the element regions 36, 37, 41, 17, 45, 46, 47, 14 and the other regions in the semiconductor substrate 11 is perfect, which will never allow the generating of parasitic effects.

IPC: G01N27/41
Filed: 1986-04-14
Abstract: PURPOSE:To make it possible to realize cultivation environment of tissue cells, etc., in an ideal state, by correcting a gas concentration obtained from a heat- conductivity type sensor on the basis of an oxygen concentration obtained from an oxygen sensor and calculating carbon dioxide concentration in a controlling device. CONSTITUTION:In a gas concentration detecting device 15 for feeding carbon dioxide and oxygen to a cultivation chamber 5 and creating a given environment in a cultivation house 1, the gas concentration is taken out as a voltage value by a heat-conductivity type sensor 24 exposed to a gas to be measured. In an oxygen sensor 25, the oxygen concentration in the gas to be measured in taken out as a current value. In a controlling device consisting of a microcomputer, the gas concentration obtained from the sensor 24 is corrected by the oxygen concentration obtained from the sensor 25 to calculate the carbon dioxide concentration. As a result, a cultivation environment, e.g. tissue cells, etc., can be realized in an ideal state. Since the carbon dioxide concentration can be detected by an ordinary heat-conductivity type sensor, a small-sized apparatus having high stability can be realized.

Title: Oil component densitometer
Inventor: FUJII HIROSHI
IPC: G01N21/3577
Filed: 1994-03-30
Abstract: PURPOSE:To enable highly accurate measurement eliminating measuring errors by arranging a light source on a cell, a first filter on the side of a detector for measurement and a second filter on the detector for comparison. CONSTITUTION:An oil component absorption wavelength zone output I due to oil components contained in a sample S is outputted from the side of a detector 4 for measurement. Power I0 for reference light proportional to transmission infrared rays integrated in a range of 1-5mum is outputted from a detector 5 for comparison. Here, an oil component absorption wavelength passes to the side of the reference light, but the output level thereof is almost negligible. By an arithmetic section 13, a computation of Log (I0/I) is performed to obtain the concentration of the oil components in the sample S. Since the cell 2 is only provided with a light source 3, errors caused by the drifting of the light source 3 and the contamination of the cell 2 can be eliminated. Moreover, a first interference filter 6 is provided to pass absorption wavelengths of oil components alone on the side of the detector 4 and a second filter indicating a flat transmission characteristic is provided on the side of the detector 5 thereby enabling the removal of the effect of components other than oil components which may exist.

Title: Method for processing end surface of optical waveguide type optical element
Inventor: YAMAMOTO YUKIHIRO
IPC: G02B6/12
Filed: 1994-03-31
Abstract: PURPOSE:To process the end surface of an optical waveguide element so that light is easily made incident on it by forming it by cleaning as a surface equal to a ground surface by utilizing the change of a grating constant occurring at the exchanging time of ion. CONSTITUTION:At first, a part desired to be left as the optical waveguide is protected by a metallic film. As for metal which is used, the metal such as Ti, Al or alloy thereof can be properly used according to the exchanging source of the ion which is used later. The ion is exchanged in about several hours with benzoic acid, phosphoric acid or the like in the case of LN(lithium niobate) or LT(lithium tantalate) and in about one hour by the mixed and fused salt of two kinds of materials such as rubidium, potassium in the case of KTP or glass. By this operation, the difference of the grating constant is generated between the part where the ion is exchanged and the part where the ion is not exchanged. Then, crystal is broken just like it is cleaved. When the attached metal is removed thereafter, the same end surface as the surface which is ground and which can be optically coupled is obtained.

Abstract: PURPOSE:To provide a measuring device, in which a problem of noise due to return light to a coherent light source is eliminated, by using a transmission diffraction grating, on which luminous fluxes split by a beam splitter are incident at the angle of an approximately equal absolute value. CONSTITUTION:A luminous flux emitted from a coherent light source 10 is divided into two fluxes by a beam splitter 102, and the split luminous fluxes are incident on a transmission type diffraction grating 106 at the angles of an equal absolute value.

At this time, diffracted light (d) is not diffracted in the second time incidence on the diffraction grating 106 but turned into diffracted/ transmitted light (f). On the other hand, transmitted light (e) is diffracted in the second time incidence on the diffraction grating 106 and turned into transmitted/diffracted light (g). These two luminous fluxes (f), (g) are incident on the same point on the beam splitter 103 to be connected together. A part of the combined luminous flux is directed to a detector 104, while another part is directed to a detector 105 at 90 deg. phase difference.

Abstract: PROBLEM TO BE SOLVED: To make small leaking transmission sound which is transmitted through an air suction duct at sucking air by providing at least a low permeable part of low air permeability and a high permeable part of high air permeability on a porous wall part. SOLUTION: Intensity of transmission sound transmitting an air suction duct 20 is not identical but is different at the air cleaner side 20a and the outside air suction side 20b, with the former being larger than the latter.

On the air suction duct 20, a low permeable part, an intermediate permeable part, and a high permeable part are formed in the order, from the air cleaner side 20a toward the outside air suction side 20b. In this way, leaked transmission sound transmitted through the air suction duct 20 at sucking air can be made small.

IPC: H04H20/31
Filed: 1979-07-09
Abstract: PURPOSE:To ensure an easy processing of the CM (commercial) identification signal for confirmation of the CM broadcast and then realize the effective CM identification, by giving the A/D conversion to plural numbers of frequencies of the received signals corresponding to the frequencies  forming the CM identification signal of the TV braodcast signal and then comparing the output  of the conversion with the threshold level to detect the discrimination signal. CONSTITUTION:At the receiving side, the channel frequency of the prescribed broadcast station  is extracted out of the TV multiple broadcast sent from antenna 51 and by tuner 52 and then  made to pass through BPF561-563 corresponding to frequencies f1, f2 and f3 which were selected  during the transmission to receive rectification and smoothing 571-573. And the digital signals  obtained through A/D conversion 581-583 are sent to threshold level deciding circuits 601-603.  These signals are then compared with the threshold level of threshold level control circuit 61, and  the comparison output is supplied to distance deciding circuits 621-623 to be compared with discrimination signal pattern 63. When the distance (bit number) becomes less than the fixed level,  the discrimination signal is detected to be then sent to computer center 4 via micro CPU65. Thus the CM identification signal for confirmation of the CM broadcast can be processed easily, ensuring an effective CM identification.
