Abstract: PURPOSE:To eliminate the need for complicated operation by allowing a subscriber during extension mutual calling to dial a called extension number after the specific operation so as to call back automaticaly the opposite subscriber when the extension is hooked off. CONSTITUTION:In extension mutual connection between a subscriber C being a called extension and a subscriber B being an opposite party to a subscriber A, when the hooking by the subscriber A is detected by a hooking detection circuit (HKD)2 via an SW1, the HKD2 transmits a detection signal to an ID4. A talking subscriber identification circuit (ID)4 identifies that the talking party is the subscriber B from the said detection signal, stores the opposite subscriber information and starts a connection controller (CC)5. Then the CC5 gives a command to the SW1 to connect the subscriber A to a register (OR)3, the OR3 counts a dial number of a called extension number (number of the subscriber C) from the subscriber A and transmits the called extension number information to the CC5 (registration of callback service). When the subscriber C hooks off, the CC5 checks the presence or absence of the registration of the callback service and when the service is registered, the CC5 calls the subscriber B via the SW1.

Title: Work machine controller for construction machinery
Inventor: ASAYAMA YOSHIO
IPC: G05B24/02

Abstract: PURPOSE:To increase a dynamic range of a fine operation area and a fine control area by providing a function generating means to produce a command for opening amount of an operation valve which has a small variation factor of opening amount in the fine operation area of an operation lever. CONSTITUTION:A function generating circuit 7 produces a command for opening amount of an operation valve having a small variation factor of opening amount at least in a fine operation area of an operation lever 1 according to the position of the lever 1. Then the circuit 7 produces a command for opening amount of an operation valve 16 having a large variation factor of opening amount. Thus the valve 16 moves up immediately to a command level of opening amount where the valve 16 starts to open when the shift amount of the lever 1 is set outside a 0-20% range (a 100% shift amount of the lever 1 defined between the neutral and maximum positions) and has a small variation factor of opening amount up to 50% to be opened to its full width within a 50-90% range. In such a way, the dynamic range of fine operation area and a fine control area are increased. Then the operability is improved for a work machine.
