Title: Correction making system by reed solomon coding and decoding system
Inventor: ITOI TETSUSHI
IPC: H03M13/00
Filed: 1984-07-02
Abstract: PURPOSE:To improve the correction accuracy of a cross-intersleeve code by relating the correction classification judgement of a code C1 and succeeding processing to the correction making processing of a code C2 to be performed next. CONSTITUTION:Both C1 and C2 decoders process syndromes and classify correction judgements into (a) no error, (b) 1-symbol correction, (c) 2-symbol correction, and (d) correction fail. The C1 decoder outputs data as it is at the time of (a) and (d) or after correction at the time (b). When it is decided that there are two error positions at the time of (c), the data is outputted after being corrected and when not, the output is outputted without being corrected and error information (C1 flag) is set. For the code C2, said classification judgement is made to perform processing, but when the number of error positions is not two in the correction (c), the data and flag are outputted as they are and when the number of flags are more than a specific number, they are outputted as they are. When not, two-symbol corrections are made if there are flags at all error positions and the flags are reset to output data. In other cases, the data are outputted as they are while flags are set.

Title: Melt spraying on electronic circuit construction material
Inventor: INOUE KOUICHI
IPC: H01C17/10
Filed: 1978-11-06
Abstract: PURPOSE: To obtain uniformly distributed film thickness by a mechanism wherein melt-spraying guns are connected along the transfer direction of substrates, melt- spraying guns being supported perpendicularly against the surface of the substrate to be sprayed, and are moved reciprocatingly in the direction orthogonal to the transfer direction of the substrates.  
     CONSTITUTION: Electronic circuit substrates 2 are transferred in one direction and numbers of melt spray guns 1, 1' are arranged to permit melt spray to perpendicularly impinge on the surface of the substrates 2. The guns 1, 1' are reciprocated so as to cross the direction of substrate movement. Increasing the number of guns in this way permits film thickness distribution to be the same on the face a-a' and b-b' and further allows the center face c-c' between the a-a' and b-b' to have a half of thickness and twice the frequency. Thus, further increasing the number of guns will increase the number of faces having the same thickness with the face b-b' of the electronic circuit substrate 2, providing better uniformness to the film on the substrate.

Abstract: PROBLEM TO BE SOLVED: To eliminate the error in distance measurement due to the difference in the intensity of reflected wave by detecting the crest value of received wave and correcting the distance data based on this crest value. SOLUTION: A laser diode 39 radiates laser light H by a drive signal from an operator part 33. Due to swinging of a mirror 47, the laser light H sweeps and radiates.
