Title: Method for connecting steel pipe
Inventor: YAMADA MOTOSHIGE
IPC: B23K33/00
Filed: 1980-07-01
Abstract: PURPOSE: To form excellent welded portions with a lower reduction ratio, by expanding the end of one steel pipe and shrinking the end of another steel pipe and by performing the welding after the shrinked end is inserted into the expanded end, when steel pipes are connected by welding.  
     CONSTITUTION: When steel pipes 1 and 2 are connected by welding, the end 1 a  to be connected of a steel pipe 1 is expanded and the end 2 a  of another steel pipe 2 is shrinked. The shrinked end 2 a is inserted into the expanded end 1 a , and both pipes 1 and 2 are welded by forming fillet welded portions 3 by a circumferential fillet welding. When this method is applied, the reduction ratio can be reduced than other methods in which only one pipe is expanded or shrinked, and no cracks will occur at the welded joint. Thus excellent joints are formed.

IPC: H04Q3/42
Filed: 1984-05-02
Abstract: PURPOSE:To detect an error also in incorrect transfer data by conneting plural inversion circuits for inverting parity bits outputted from plural transmission registers, decoding a selecting singnal and inhibiting the operation of the inversion circuit corresponding to the transmission register to be selected. CONSTITUTION:The transmission registers 11-14 store 8-bit data and 1-bit parity bits. The 8-bit data outputs from the registers 11-14 are inputted to a selecting circuit 2 and parity bit outputs are inputted to the circuit 2 through the inversion circuits 71-74. The circuit 2 inputs selecting signals 41, 42, selects the outputs of an optional transmission register and its corresponding inversion circuit in accordance with the selecting signals and supplies the selected outputs to a receiving register 3. On the other hand, a decoder 5 inputs selecting signals 41', 42', decodes these signals and turns signal lines 61-64 corresponding to the transmission register to be selected to the high level. Consequently, the inversion circuit connected to the transmission register to be selected is inhibited at its inverting operation. Thus, an error can be detected even if the inversion circuit executes malfunction.

Abstract: PURPOSE:To shift the position of an article in the horizontal direction for the axis center by installing a supporting board which permits an article to shift horizontally on the plane vertical to the shaft, when a wedge member interposed between the article and the shaft is demounted. CONSTITUTION:A groove 11g for laying a timing belt is formed on the outer peripheral surface of a transmission wheel (article) 11 axially supported in horizontal state, and engaging rings 18a and 18b are installed onto the upper and lower edge parts. A sliding surface 19 is worked onto the reverse surface of the transmission wheel 11. A supporting board 20 is installed onto a shaft 10 through a clamp element 21. A flat surface part 20a, supporting part 20b, and an opened port 20c are formed on the supporting board 20. Since, with such constitution, a tension due to the timing belt is not applied onto the transmission wheel 11, a wedge member 12 can be easily demounted. Though, in this case, the transmission wheel 11 is applied with its dead weight, drop of the transmission wheel is prevented, since the supporting transmission wheel 11 is positioned on the supporting board 20. Further, only the transmission wheel 11 can be shifted in a direction only by the distance L on the supporting board 20.
