Title: Oxygen concentration detecting device for fan heater
Inventor: YAMAGUCHI HIROSHI
IPC: F23N5/12
Filed: 1986-06-20
Abstract: PURPOSE:To surely detect, without error, a reduction of oxygen concentration when the burning rate is small by automatically modulating the burning rate to increase the flame ionic current at a moment when the flame ionic current drops to a level which is higher than a predetermined level by a certain amount. CONSTITUTION:The flame ionic current is measured to determine detection levels C, D of the ionic current of flame whose reduction of oxygen concentration is to be detected. When the oxygen concentration is reduced, the flame ionic current is also reduced. When it is reduced to the level D, the burning rate is increased and the flame ionic current is also increased. As the oxygen concentration is reduced, the flame ionic current is reduced, and when it is reduced to the level C, the burning is stopped and a warning lamp is illuminated.

IPC: G06Q50/00
Filed: 1993-06-17
Abstract: PURPOSE:To prevent the deterioration of reliability as a system by replying a shipping schedule corresponding to the change of production which suddenly occurs. CONSTITUTION:A process plan where respective processes are made to correspond to orders is generated by using a process plan generation part 12, and a process results collection part 16 collects advance results in the production line of the process shown in the process plan. The shipping scheduled date of the orders which are made to correspond to the processes from the processes where the advance states are shown by the advance results by using an advance schedule reply part 14 is calculated. Thus, the shipping scheduled date becomes the reply based on the advance states of the processes in the production line. Thus, the reply of the shipping schedule corresponding to the change of production which suddenly occurs can be given. Then, the erroneous reply of the shipping schedule caused by the fact that the process already corresponding to the order is made to correspond to the different order, can be prevented since the processes are made to correspond to the orders.
