Title: Coder and decoder for error correction code and decoding method use the same
Inventor: INOUE TORU
IPC: H03M13/00
Filed: 1990-03-02
Abstract: PURPOSE:To set the reliability of 2nd information to an optional value independently of the reliability of 1st information by superimposing a 3rd linear code only to a part of the inspection symbol part of the 1st linear code of a product code to reduce the effect of a pseudo error in the case of multiplex/demultiplex. CONSTITUTION:The coder is provided with a 1st coding section 4 coding an input signal into a (n1, k1, d1) linear code whose code length is n1, whose information symbol length k1 and whose minimum symbol length is d1 in a 1st direction based on 1st information of k1Xk2 digits and a 2nd coding section 5 coding the input signal into a (n2, k2, d2) linear code in a 2nd direction. Moreover, in order to code the 1st information into the product code of n1Xn2 digits, a 3rd coding section 6 coding the information into the 3rd linear code whose attribute is (n2, kx, d3) based on the 2nd information of rXkx digits (r<(n1-k1), kx<n2) and with a coding control circuit 3 superimposing the 3rd linear code onto the inspection symbol part of the product code. Thus, the error correction capability of a superimposing code is set freely and a received word composed of the superimposing code is simultaneously recovered at the decoding processing in the direction of the product code at the decoder side.

Inventor: WATANABE KATSUROU
IPC: C01B17/36
Filed: 1982-03-31
Abstract: PURPOSE:To accelerate flocculation and settling and to enhance the work efficiency of filtration by adding anionic polyacrylamide having a prescribed mol.wt. to an alkalie hydrosulfide soln. contg. fine particles of metallic sulfide and org. matter and having a prescribed spent rate. CONSTITUTION:When the spent rate of an alkali hydrosulfide soln. contg. fine metallic sulfide, org. matter, etc. recovered from a chemical plant is below a prescribed value, the soln. is reacted with H2S to adjust the spent rate to >=90.1%. Anionic polyacrylamide having >=2 millions mol.wt. is then added to the soln. After agitating the soln., formed flocks are settled, and the fine precipitate is filtered off. Thus, the fine metallic sulfide and org. matter in the alkali hydrosulfide soln. are easily filtered off.

Filed: 1982-03-31
Abstract: PURPOSE:To embed SiO2 in a groove providing a flat separating layer by a method wherein single Si or multiple crystal indefinitely formed Si is grown on a concave bottom surface of Si substrate and an Si film formed into a mask from Si3 N4 film is selectively oxidized. CONSTITUTION:SiO2 14 on p type Si substrate is coated with Si3N4 forming a concave groove 17 by means of reacting ion etching to be coated with Si3N4 19. Then Si3N4 19 is reacting ion etched again leaving Si3N4 19 on the side walls of the groove. B ion 4 is implanted into exposed substrate 13 to form p<+> layer 5 selectively growing Si 22 and selectively oxidizing the same to form field oxide film 23. Si3N4 15 and SiO2 14 are removed. Gate electrode will not be broken in case a wiring is formed since the surface of element forming region 20 and separating layer 23 are on the same plain while the distortion of side walls from the substrate is little preventing any defect from happening since they are coated with Si3N4 to grow SiO2.

Title: High frequency medical heat treatment device
Inventor: YAMAMOTO GORO
IPC: A61N1/40
Filed: 1995-03-10
Abstract: PURPOSE: To reduce concentration of an electric field at a living body surface part on which an electrode is applied, and reduce temperature rise at the living body surface part and electric stimulation by high frequency waves. CONSTITUTION: High frequency energy is supplied from a high frequency generator 9 to electrodes 3, 4 applied to a surface of a living body 2 through cooling pads 5, 6. Inductance members 7, 8 comprising rectangular copper plates are connected to the electrodes 3, 4, so a resonance current flows through the inductance members 7, 8 and the living body 2. A high frequency current inputted to the electrodes 3, 4 is bypassed to the inductance members 7, 8, and the high frequency current supplied to edge parts of the electrodes 3, 4 is reduced, so strength of an electric field at a living body surface part where the electrodes 3, 4 are applied is weakened, thereby temperature rise at the living body surface part and electric stimulation of high frequency waves are reduced.

Filed: 1989-03-03
Abstract: PURPOSE:To obtain a copy image of invariably proper density by reduce the quantity difference between the quantity of light when copy conditions are set owing to the overshoot of a light source and the quantity of light when image density on a document is read. CONSTITUTION:An exposure element 4 detects reflected light from the document 1 during preliminary scanning operation and a control part 5 adjusts the turn-on voltage of a halogen lamp 3 according to the detection output. For example, when the image density of the document is high, the turn-on voltage of the halogen lamp 3 whose exposure quantity needs to be increased is set high, but when the image density is low, the turn-on voltage of the halogen lamp 3 whose exposure quantity needs to be decreased is set low. Then when a main scan is made following the preliminary scan, the halogen lamp 3 is turned on with the turn-on voltage set corresponding to the image density and exposure as to the document 1 is carried out to form the copy image corresponding to the document image on a sheet 1. Consequently, the difference between the quantity of light at the time of the image density detection and the quantity of light at the time of copy condition setting is reduced to obtain the copy image of invariably proper density.

Title: Solid-state image sensing device
Inventor: OSAWA SHINJI
IPC: H04N5/357
Filed: 1993-03-12
Abstract: PURPOSE:To prevent a deterioration in picture quality, by providing each contact between backward wiring layers with a horizontal frequency of two picture elements so that a spatial frequency of the contact pattern becomes equal to half of a sampling frequency. CONSTITUTION:When an aluminum contact 42 is put at every two picture elements, a spatial frequency (fc) becomes equal to half of a sampling frequency (fs) in a contact pattern. Then, the spatial frequency (fc) is put out of a band of image signals, and a deterioration in picture quality is diminished because the noises out of frequencies at the image signal band are not effective. In this case, a polysilicon contact 41 for connecting a transfer unit 22 and a buffer electrode 31 is not put at every two picture elements, but this contact 41 is included in the lowest layer, and not effective. Consequently, an increase in noises can be prevented even when all the picture elements are read out or EVS is carried out, and the picture quality can be improved.

Abstract: PURPOSE: To widen a detection range with detection sensitivity maintained in an optical displacement sensor for highly accurately detecting a change in position of an object to be detected. CONSTITUTION: A light beam emitted from a light projection element 2 via a projection lens 3 irradiates an object 4 to be detected, and reflected light is received by a PSD 6. Output current I1 , I2 of the PSD 6 is input to an arithmetic circuit 11.

The broken-line approximation circuit 14 performs conversion so that sensitivity at a detection reference point increases and sensitivity at its peripheral positions decreases. Thus, a sensitivity range is widened and attachment work of an optical displacement sensor becomes easy.

Therefore, the pressing force applied on the upper surface of the bead is transmitted to the bottom surface through the intermediary of the convex part, while the bending moment MF acting on the end part of the bead acts around a supporting point Q, and thus floating up force for the end part is lessened. Therefore, the pressing force is converted effectively into the bonding force.
