Title: Automatic answering system of terminal
Inventor: GOMI ATSUSHI
IPC: H04M1/64
Filed: 1997-05-27
Abstract: PROBLEM TO BE SOLVED: To set an automatic answering function and an automatic response message registration with a simple operation by setting an automatic answering mode through an recording operation of a response message. SOLUTION: An automatic answering function is in an off state when power is on and decides whether a response message based on a response recording key operation by a user is recorded or not. When the response message is recorded, it is decided whether the response message is erased or not after an automatic answering mode is set. When the responser message is erased, it becomes in automatic answering mode, and when it is not erased, it is decided whether the response message is recorded or not. The switching of an automatic answering on/off mode is automatically performed in dependence on the existence of a response message. An operation that makes the automatic answering function effective and a recording setting operation of a response message are carried out by operating a setting switch only one time.

IPC: B29C45/26
Filed: 1988-06-23
Abstract: PURPOSE: To carry out quick replacement of a stamper by an injection molding device wherein a disc with information structure on one side is made from a synthetic material and a coupling device is provided to couple a guard ring with a second section. CONSTITUTION: An injection molding device is provided with a quick-fastening device to quickly fasten a guard ring 17 to the first mold section. Provided is a coupling device which couples the guard ring 17 to a mold section 2 only when replacing a stamper 16 and which couples the guard ring 17 to the second mold section 2 when the mold is almost closed. In order for the guard ring to be at the coupling position, it is necessary to have the ring turned clockwise. To this end, a sliding rod 19A is slid to the right direction and 19B, to the left. The ring's rotation enables the insertion top 33 of the second insertion coupler to couple to an insertion slot 37. When the mold is at an open position, the guard ring which is being coupled to the second mold section is detached from the first mold section.  Further opening of the mold enables the stamper 16 to be removed from the first mold section 1 with ease together with a support section 12.
