Title: Nail interval measuring apparatus
Inventor: SATO SHOJI
IPC: G01B7/14
Filed: 1990-09-12
Abstract: PURPOSE:To measure an interval between two nails accurately from a moving distance of a touch sensor by arranging the touch sensor means to touch each of the two nails on a game board and a sensor moving means. CONSTITUTION:First, with the rotation of a drive motor 2 counterclockwise, a nail contact detecting section 1 is moved to the left. Then, a proximity switch 11 is judged whether it is turned ON or not. Until the proximity switch 11 is turned ON, the drive motor 2 continues to rotate counterclockwise and when it is tuned ON, the drive motor 2 is halted. When the drive motor 2 is stopped, a counter N is cleared and the drive motor 2 rotates clockwise. A value of the counter N is incremented while the nail contact detecting section is moving to the right of the motor 2, and when the proximity switch 12 is turned ON, the motor 2 stops and the counter N is halted. A distance between the two nails is computed based on the current value of the counter N.

Abstract: PURPOSE:To simplify the operation for restarting the titled equipment after abnormality is cut off by automatically retransmitting/receiving based on control information and transmission/reception information stored in a memory means at the time of restarting after the abnormal cut off of the transmission/reception occures. CONSTITUTION:An abnormal cut off may occur during a transmission because of a faulty in a power source, eroneous operation, etc. If it actually happens, since a part of the control file and the information file in a mass storage 6 is stored in a battery bakup memory RAM 3, the line number, error check code, priority order of the destination as well as a transmission data are remainning in the memory. Thereafter, at the time of restarting, a busy flag is checked, and if not reset, a control information for transmission is checked, and thus an abnormal fils is decided. Then, the state of data on the memory is checked by using the check code of the transmission file and a transmission file data, if they are not destructed, the line is connected, and the page at which the interruption occurred is retransmitted. If the data are destructed, the data are written from the storage 6, to inform the operator of occurrence of abnormal cut off, transmission stoppage, and restarting.
