Title: Disk controlling system
Inventor: MATSUSHIMA HITOSHI
IPC: G06F3/06
Filed: 1985-08-19
Abstract: PURPOSE:To control easily even a disk device of a different attribute by writing in advance attribute information of each disk device used by a control device, in a place determined in advance in a storage area of the disk device. CONSTITUTION:When a control device 2 executes an operation at the start, an initializing program is called first from an initializing program area 22. The initializing program reads out attribute information on all disk devices 3(0)-3(n) which are connected under a control of the control device 2, from each attribute information area 31(0)-31(n), and stores it in the corresponding control information area 23(0)-23(n). Subsequently, a control program in a control program area 21 is started, and in case when a data processing of the disk device concerned 3(i) is executed, based on this control program, the control program executes an attribute-conversion processing control and a data control which have matched the attribute information stored in the control information area concerned 23(i).

IPC: F23R3/40
Filed: 1987-07-23
Abstract: PURPOSE:To make it possible to stabilize gas phase combustion by providing a vortex flow generating part between a catalytic combustion part and a gas phase combustion part to throttle the flow passage, and thereafter abruptly to expand the same. CONSTITUTION:A fuel mixture from a catalyst body 7 and an auxiliary fuel mixture from an auxiliary fuel nozzle 12 are formed into desire mixed fuel flows and sent downstream and contracted gently at a throat part 13. Thereafter, these flows are abruptly expanded at a gas phase combustion part 14, and a stable vortex flow (circulating flow) 15 is produced along the circumference of the gas phase combustion part at the rear part of the throat part 13. This vortex flow 15 is not almost affected even if a disturbance is produced in a mixed flow passing the center of the flow path of the throat part 13, and hence a stable vortex flow is formed. Thus, since a vortex flow is produced along the circumference of the gas phase combustion part, a flame holding effect is produced, and hence even if local misfiring is generated, it is not enlarged but an original uniform combustion state is restored immediately, and a stable gas phase combustion can be carried out.

Abstract: PURPOSE:To set up the optimum stopping time for a riding cage necessary for discharging dehumidified water without lowering transportation efficiency and operation efficiency of an elevator by setting up the time during which a door is open at the floor undermentioned in proportion to the time for which the riding cage is apart from the floor at which the dehumidified water is discharged, about operation control for the elevator equipped with a tank storing dehumidified water of a cooler. CONSTITUTION:When a riding cage CAR returns to the lowermost floor again within about 5 minutes after starting from the lowermost floor, a door opening waiting time is set up to the same as a usual case of operation on an elevator, about four seconds. When opening and closing time of the door is summed up thereto, the stopping time of the riding cage CAR becomes about 10 seconds. It becomes that dehumidified water in a tank TK is discharged during that time, but as the time for which the riding cage CAR is apart from the lowermost floor is within 5 minutes in this case, the dehumidified water in the tank TK is not much, therefore it is possible to discharge the water completely in this about 10 minutes.
