Title: Error number estimate method and bch code correction method
Inventor: HIRAYAMA HIROSHI
IPC: H04N19/00
Filed: 1994-02-21
Abstract: PURPOSE:To correct an error at a high speed with a small scale circuit by estimating number of errors based on a syndrome obtained through arithmetic operation from a reception signal and obtaining a coefficient and a solution of an error location polynomial through data conversion and addition according to a correction program. CONSTITUTION:A syndrome arithmetic circuit 2 calculates a syndrome (S0, S1, S3) from a sub frame (reception polynomial) of one frame comprising voice data and a BCH code from a RAM 1. A correction discrimination circuit 4 uses a data conversion ROM 3 and an adder circuit 7 implementing E-OR addition (+) to arithmetic operation and discrimination shown below based on them according to a program stored in a program ROM 6. That is, the circuit 4 obtains the polynomial of C=S1<3>+S3 and discriminates no error, 1-error correction or 2-error correction depending whether or not the S0 is 0 and whether or not each absolute value of the S1, S3 and C is zero, and a correction processing circuit 10 implements corresponding correction processing. Thus, the error is corrected at a high speed by using the small scale circuit.

IPC: G06T7/00
Filed: 1992-02-07
Abstract: PURPOSE:To provide the system and method for inspection which has sufficient correspondence to the actual operation of an image processor and can inspect the image processor in a short time. CONSTITUTION:A work station(WS) 1 sends part of a control program, stored on a hard disk(HD) 4, to an I/F part 2. The I/F part 2 sets the operation mode and inspection image processing area of the body 3 to be inspected according to the control program and sends a request for image data to be applied to the body 3 to be inspected to the WS 1. The WS1 loads image data that the I/F part 2 requires among plural image data stored on the HD 4 and reference data corresponding to the image data to the I/F part 2 and a reference data memory 16. The I/F part 2 applies the image data to the body 3 to be inspected and sends image data outputted by the body 3 to be inspected to the WS1. The WS1 compares the image data outputted by the body 3 to be inspected with the reference data stored in the reference data memory 16 to decide whether or not the object body 3 is normal.

Title: Thin construction battery sealing method
Inventor: YAMAMOTO KOHEI
IPC: H01M6/12
Filed: 1989-02-02
Abstract: PURPOSE:To carry out the final sealing process securely in a short time even though electrolyte has oozed at the periphery by heating and pressurizing a sealant in the form of window case with small wall thickness in the condition that this sealant and a one in similar form having large wall thickness both being fusion welded to a positive and a negative terminal plate, respectively, are facing each other, and by fusion welding the two together. CONSTITUTION:A downward facing piecepart on the neg. electrode side is put on a piecepart on the pos. electrode side. Now that part of a neg. electrode terminal plate 5 which is covered with a sealant 6 in the form of window case having small wall thickness transfers onto the oversurface of a sealant 2 in similar form having large wall thickness fusion welded to a pos. electrode terminal plate 1, and a sheet-shaped lithium neg. electrode 7 contacts a separator 4 on its oversurface. In this condition, a heater made in the form of a picture frame is applied to the peripheral parts on the oversurface of the neg. electrode terminal plate 5, which is thus heated and pressurized. Because the sealant 6 with small wall thickness is very thin and fusion welded previously to the neg. electrode terminal plate 5 to be heated, the two sealants 2, 6 with different wall thicknesses can be fusion welded together in a very short heating time.

Filed: 1979-02-27
Abstract: PURPOSE: To convert an input AC signal to a voltage signal corresponding to the effective value with a high precision by a simple circuit constitution using a pair of semiconductor elements having logarithmic characteristics.  
     CONSTITUTION: AC input voltage v is applied to logarithmic conversion circuit LC through absolute value circuit AB. This LC has a pair of semiconductor elements Q 1  and Q 2  having the same logarithmic characteristic on the feedback path of amplifier OP1. Voltage v 1  obtained from LC is applied to correction circuit CMP having semiconductor elements Q 3  and Q 4  having the same characteristic as Q 1  and Q 2 . Collector voltage v 3  of Q 3  is given to integrator INT consisting of differential amplifier OP21, which has capacitor C 1  on the feedback path, and resistance R21. At this time, current I 0  flowing to Q 3  is large; and when v 3  is increased to positive, output voltage V 01  of INT is changed from the negative direction to the positive direction, and output current I 0  of voltage current.converter VI is reduced to reduce v 3 . In this case, I 0  is so controlled that v 3  may be zero, and the output of INT becomes a fixed value. As a result, output voltage V 01  becomes a voltage corresponding to the effective value of the input AC signal.

Title: Method of deciding presence or absence of erroneous detection at time of detecting central position of guide grooves of optical information recording disk
Inventor: MIWA YASUYUKI
IPC: G01B21/00
Filed: 1988-02-05
Abstract: PURPOSE:To easily discriminate whether a disk substrate is defective which is not within a disk substrate administration range or not by setting the radius of the guide grooves of the disk substrate as the range for administrating the product fluctuation of the out of roundness and detecting the radius or out of roundness. CONSTITUTION:Plural measurement points are selected on the circumference of the guide grooves 25 of the optical information recording disk and the radius R0 of the approximate circle running the measurement points is calculated. Whether the radius R0 exists in the prescribed administration range or not is then decided. Namely, the radius R0 of the approximate circle increases in the difference (out of roundness) between the max. value and the min. value of the radius R1 of the guide grooves if the defect, dust, etc., of the recording sensitive material exist. The defective substrate which is not within the administration range is thus elucidated. The exact detection of the defective substrate is thereby enabled and the product reliability is improved.
