Title: Method of vulcanizing rubber molded item
Inventor: ARAKI NORITAKE
IPC: B29C43/58
Filed: 1983-05-16
Abstract: PURPOSE:To make it possible to set or confirm the vulcanizing conditions within a short period, and to confirm continuously the vulcanizing conditions during the production in a non-destructive way, by vulcanizing a rubber molded item with it being held by a press, and detecting the peak of the work holding distance of the press thereby terminating the vulcanization.

Title: Stroke limit checking system
Inventor: KAWAMURA HIDEAKI
IPC: G05B19/19
Filed: 1986-04-15
Abstract: PURPOSE:To prevent a machine from exceeding a stroke limit, by returning the last pulse that has been sent, to an absolute register, when a value of a machine register has exceeded the stroke limit. CONSTITUTION:A pulse distributing means 11 sends a pulse DELTAx to a register at every prescribed time so that a value of a machine coordinate register 13 coincides with a value of an absolute register 12. On the other hand, when the value of the register 13 has exceeded a value of a stroke limit register 14, an inhibiting means 15 informs it to the distributing means 11. When it is informed, the distributing means 11 stops distributing a pulse, and also, returns the pulse DELTAx which has been sent from the register 12 before said notice is given, to the register. Accordingly, since the last pulse DELTAx that has been sent to the register 13 is not outputted to an error register 16, the machine does not exceed a stroke limit.
