IPC: H04L7/10
Filed: 1979-05-07
Abstract: PURPOSE: To enable the data transmission simply and surely, by simultaneously transmitting the synchronizing signal to determine program searching other than the data to be transmitted, and the redundancy signal to distinguish this signal.  
     CONSTITUTION: When the terminal unit I is selected in the data collection station II, the clock pulse in synchronizing with the clock pulse from the clock pulse oscillator 10 is fed to the terminal unit I and the bit counter 20, digit counter 21 are set. After that, when the clock pulse is succeedingly fed, the indication value of the meter M can be read in. Since the redundancy code terminal next to the 10 0  digit of the digit counter 21 is open, after the redundancy code is selected, the transistor TR 1  is not conductive while the bit counter circulates, then the redundancy code can be obtained. Accordingly, the synchronizing signal and the data signal can surely be distinguished.

Title: Welding method
Inventor: KIMURA IKUO
IPC: B23K9/02
Filed: 1988-03-08
Abstract: PURPOSE:To perform accurate welding even when there is the large difference in plate thickness between both plates by superposing the thin plate on the thick plate and performing welding of an end of the thin plate exposed from a presser tool to a part of the thick plate by using a plasma arc while the thin plate being pressed from above by the presser tool. CONSTITUTION:The Al thin plate 3 is pressed on the Al thick plate 2 by the presser tool 8 by a pressure press 9 and both plates are stuck together. A switch of a welding power source 5 is charged and torch 10 for plasma arc welding is fitted to the position of the end 7 of the Al thin plate 3 and the plasma arc is projected and the end of the Al thin plate 3 exposed from the presser tool 8 and a part of the Al thick plate 2 are molten and stuck together. The torch 10 for plasma arc welding is moved at a proper speed and welding is performed continuously. Since the presser tool 8 is made of stainless steel having the melting point higher than Al, it is not molten. By this method, since a melting unnecessary part of the thin plate is covered by the presser tool, even when the plate thickness of the thin plate and the thick plate is thick, the accurate welding can be easily performed.

Abstract: PURPOSE:To improve the efficiency of drawing up documents through restoring the drawing-up device to a state right before selection, by pushing a cancel key when ''kanji'' is selected erroneously. CONSTITUTION:When an operator inputs information on the rendering of ''kanji'' in ''kana'' (Japanese syllabary) from keyboard 1, ''kanji'' characters that correspond to the rendering set in ''kanji'' dictionary contents buffer 6 are displayed at the prescribed position of display 9. If the operator when selecting a desired character over a look at numbers on the display pushes a wrong number key erroneously, different ''kanji'' is selectively displayed, so cancel key 1-2 on keyboard 1 is pushed to display the ''kanji'' having the rendering on display 9 again. Therefore, the operator pushes the correct number key to perform the documentation extremely rapidly.
