Title: Data transfer method
Inventor: AOKI KIYOSHI
IPC: G06F13/28
Filed: 1984-02-15
Abstract: PURPOSE:To prevent data from misrecognition by providing a rewriting monitoring bit in an information word and deciding the information word as a normal one from the processing result of the bit over plural words. CONSTITUTION:A data repeating device 1 transfers data transmitting from a cyclic transmission device TC to a DMA controller 4 together with data updated by regarding the rewriting monitoring bit JA as ''0'' when the data from the TC is normal. When the rewriting monitoring bit JA in the data is ''0'', the rewriting monitoring bit JA ''0'' and the data are stored in a memory 6 so as to attain DMA. A CPU5 scans the data at a period shorter than a TC transmission cycle to check the rewriting monitoring bit JA. When the JA is set up to ''1'', the JA is ignored or invalidated, and in case of ''0'', the data are processed and then the JA is set up to ''1''. After processing the JA over plural words, the CPU5 regards the data as valid one first and then processes the JA.

Filed: 1997-02-12
Abstract: PROBLEM TO BE SOLVED: To refer to drawing information by means of a general-purpose personal computer by converting drawing information into a file system which can display software and transferring converted data through a network. SOLUTION: When the transfer instruction of drawing information is started, a control means 1 reads drawing information from a storage means, converts it into the prescribed file system and temporarily stores it. The control means 1 inputs the addresses of PC4-6 of transfer destinations and comments to an operator. The control means 1 transfers converted data which is temporarily stored to PC4-6 of the transfer destinations through the networks as drawing information data. Thus, it is not necessary to install distribution control functions in individual PC4-6 and EWS 2 and 3, to refer to drawing information, to print the drawing and to refer to screen information. Consequently, drawing information can be referred to by general-purpose PC4-6 by converting screen information into the prescribed file system and transferring installed general-purpose PC conversion data.

Filed: 1984-02-17
Abstract: PURPOSE:To improve driving characteristic and to improve follow-up capacity of an objective lens by making the position of taking out of a lead wire from a driving coil axial symmetry to the principal axis and canceling rotational moment generated at movable parts. CONSTITUTION:A terminal substrate 101 is attached to opposite side of an objective lens holding member 9 which is a movable part, and both ends of a driving coil 7 are connected. Lead wires 102, 103 to external driving circuit are connected to lead wire pulling out positions 105, 106 of the substrate 101 which is at a position of axial symmery to the principal axis 5.
