Filed: 1995-12-01
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for a load cell for detecting the point of the time for changing a speed and to decrease trouble parts by changing the speed setting to a descending speed when the descending speed of a receiving truck for receiving slabs attains the speed higher than a casting speed. SOLUTION: The cut slab is received in the receiving truck 8 of an inverter control system and is lowered, by which the cut slab is transferred onto a pulling-up truck 11 and is ejected. At this time, the speed setting of the truck 8 is set at a zero speed in a standby state and an ASR (speed control circuit) executes P control to prevent the gravity fall. In the stage the slab descends to come into contact with the truck 8 and pushes down the truck 8, the speed setting of the truck 8 is changed to a 'casting speed-α of the slab' and the ARS emits the control torque corresponding to αin the state of the P control. When the acceleration of the descending speed of the truck 8 by the slab weight at the time of cutting the slab is detected, the set speed of the truck 8 is changed to the prescribed descending speed and the ASR is switched to PI control.  As a result, the always safe descending of the slab is assured.

Title: Telephone system
Inventor: HASE JUNKO
IPC: H04M1/57
Filed: 1998-11-05
Abstract: PROBLEM TO BE SOLVED: To prevent an unnecessary caller's number from being stored by storing only the number of a roller who completed its talking and controlling whether the caller's number is to be displayed on a display means or not in accordance with whether or not the caller's number is matched with a certain telephone number stored in a telephone book. SOLUTION: A telephone book 101 stores telephone numbers, names corresponding to these telephone numbers and display/non-display flags up to twenty parties e.g. at maximum. An incoming record 102 stores caller's telephone numbers, dates corresponding to respective caller's telephone numbers and uninformed/informed flags up to ten telephone numbers e.g. at maximum. When an incoming call is received, a control circuit 8 refers to the telephone book 101, and when the flag is not 'non-display', judges its caller's number as an 'untalking' number, registers it in the record 102 and displays the caller's number of a display means 102.  When a hand set 3 is hooked off, the control circuit 8 refers to the telephone book 101, changes registration in the record 102 to a 'talked' state when the caller's number is not 'non-display' or erases its registration from the record 102 in the case of a 'non-display' state.
