Title: Automatic working system by nc machine tool group
Inventor: ISHIZUKA SHINICHI
IPC: G05B9/02
Filed: 1982-07-20
Abstract: PURPOSE:To prevent the occurrence of an accident by discriminating the contents of a program once the program is read and generating an alarm if an erroneous code is inputted. CONSTITUTION:A central controller 10 transfers work programs to plural NC machine tools respectively. Code numbers characteristic to the respective NC machine tools are written in the beginning of the respective work programs. Each NC machine tool when reading its characteristic code number starts discriminating the code. The discrimination is performed by a discriminating means 24 consisting of a relay sequence circuit. When the code supplied to the NC machine tool is correct, a confirmation relay operates to start the work program, but if the confirmation relay does not operate for a specific time, an alarm signal is generated. Therefore, the central controller 10 transfers the correct program to each NC machine tool.

Title: Absolute encoder
Inventor: KISHI SAKAE
IPC: G01D5/244
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To prevent the correction of an absolute position from being omitted when an absolute encoder is set. SOLUTION: When a power-supply detection means 11 at an alarm-signal generator 1 detects that a power supply is turned on, an alarm-signal generation means 13 judges whether an alarm generation instruction is stored in a storage means 12. Since the storage means 12 first stores the alarm generation instruction without a backup power supply, the alarm-signal generation means 13 surely transmits an alarm signal to a host controller in a setting operation. The host controller receives the alarm signal so as to generate an alarm, and an operator knows the necessity of the correction of an absolute position. When a reset instruction is outputted by a reset-instruction generation means 14, a rewrite means 15 executes the erasure of the alarm generation instruction from the storage means 12 so as to be rewritten.
