Title: Power failure monitoring device
Inventor: TSUJI TOSHIHIDE
IPC: G08B21/00
Filed: 1991-01-24
Abstract: PURPOSE:To enable quick recovery of power supply by indicating that abnormality occurs in a unit power supply, when a power failure interrupting power suppy to any of circuit units takes place. CONSTITUTION:The relay contact fc of Flicker Relay 18 is connected in parallel with the relay contact (a) of relay A 20 and connects the normally open relay contact ro of a relay R0 with the primary side and further connects a power- monitoring lamp 22 as a load. When the power supply of all circuit units 16-1 to 16-4 is normal, the power-indicating lamp 22 is lighted. When the power supply of any of the circuit units 16-1 to 16-4 is interrupted, the power- monitoring lamp 22 goes On and OFF. When a main power supply is interrupted, the power-monitoring lamp 22 is put out. Thus, the malfuction of a control panel, etc., by the power interruption of the circuit units 16-1 to 16-4 can be recovered quickly.

Title: Back-up method for trouble analysis
Inventor: NAKAI KOJI
IPC: G05B23/02
Filed: 1990-01-16
Abstract: PURPOSE:To quickly analyze the factor of a trouble by providing a monitoring device which inputs the control data from each controller and detects the abnormality and then calling out the control data on other working machines in relation to a specific machine when the monitoring device detects a trouble of the specific machine. CONSTITUTION:A common monitoring device 10 is provided to monitor the states of a 1st controller 13, a 2nd controller 23, a 3rd controller 33, and a 4th controller 43 respectively. When the device 10 detects the abnormality of a specific controller, another controller having the operating relation to the specific controller is selected. Then the trigger signals are applied to both the selected controller and the specific one. Based on these trigger signals, the controllers 13 - 43 output their control data before and after the transmission of the trigger signals. In such a case, it is possible to immediately obtain the control data set before and after the stoppage of troubles of a fault displaying machine and its related machine since another machine related to the fault displaying machine is previously selected. Thus the factor of the trouble is quickly analyzed and therefore the discontinued time of a machine system can be minimized.

Filed: 1984-01-18
Abstract: PURPOSE:To reduce the troubles of material breakage, etc. and the off-gauge quantity of product by preventing the tension and sheet thickness of a rolling material from deviating from the scheduled values of preceding and succeeding materials even when the rolling material suddenly changes, in performing a titled control in accordance with the movement of a size- changing point during rolling. CONSTITUTION:In the case where preceding and succeeding rolling materials having original sheet thicknesses H1, H2(H1>H2) respectively are joined together by welding, and the rolling of them is started from the welding point, for instance, the roll gap is changed so that it starts from Si1 and arrives at Si2 at the time when the welding point arrives at an optional stand (i) through a certain time. At that time, the sheet thickness at the outlet side of a stand (i) changes continuously to the thickness which depends on the change of the sheet thickness at its inlet side and the changed of the roll gap and roll speed ratio of the stand (i), and an excessively small sheet thickness produces at the outlet side of a final mill as shown by the figure. When material breakage is expected because of said sheet thickness, a seize changing point is set at a certain point of the preceding material basing on the times of changing the draft and the speed so that the terminal point of sheet thickness-changing coincides with the welding point, and then the product sheet thickness is obtained as shown by the figure. Further, a method for reducing off-gauge products the minimum is also available.
