Title: Memory backup device
Inventor: NAKANISHI TAKASHI
IPC: G06F12/16
Filed: 1990-11-29
Abstract: PURPOSE:To check the backup state of a memory by providing a time measuring circuit measuring the time turning on a power supply when a capacitor for backup is filled and the time turning off the power supply when the voltage filled in this capacitor is discharged. CONSTITUTION:A time measuring circuit 5 measuring the time turning on a power supply 1 when a capacitor 7 for backup is filled and the time turning off the power supply 1 when the voltage filled in this capacitor 7 is discharged is provided to decide memory backup operation based on these time measuring data. For example, when the turning-off time is shorter than the backup possible time, data of a second RAM 8 is decided to be preserved, and when the turning- off time is longer than the backup possible time, the data of the second RAM 8 is decided as destructed. Thus, the backup state of the memory is checked without adding a new circuit.

Title: Steam turbine plant
Inventor: OHIRA HIROYUKI
IPC: F01D15/08
Filed: 1996-12-13
Abstract: PROBLEM TO BE SOLVED: To suppress the exhaust steam temperature of a boiler feed water pump driving turbine so as to be able to operate without lowering reheat steam temperature by making a steam extraction point of extraction steam for driving a turbine for the boiler feed water pump driving changeable over to another steam extraction point on the lower pressure side at the time of partial load. SOLUTION: At the time of high load of a steam turbine plant, a stop valve 19 is opened, while a stop valve 21 is closed, and extraction steam extracted from an intermediate pressure turbine 4 by an extraction steam pipe 14 is supplied to a boiler feed water pump (BFP) driving turbine 15 to drive it. At the time of partial load, the stop valve 19 is closed, while the stop valve 21 is opened, and extraction steam lower in pressure than extraction steam in the extraction steam pipe 14 is supplied to the BFP driving turbine 15 from an extraction steam pipe 13c via a steam supply pipe 20. That is, at the time of partial load of the plant, seam supplied to the BFP driving turbine 15 is switched to extraction steam lower in pressure than that at the time of full load.  The exhaust steam temperature of the boiler feed water pump driving turbine is thereby lowered to improve plant efficiency at the time of partial load.

Title: Moving machine having active-type sensor
Inventor: KAWASE KATSURA
IPC: G05D1/02
Filed: 1991-11-26
Abstract: PURPOSE: To make moving machines mounting active sensors using the same energy wave coexist closely to each other. CONSTITUTION: The moving machine enters an exclusive transmission mode with respect to the transmission of an energy wave when interference can occur between its active sensor and those of other moving machines. Before transmitting the energy wave, the moving machine judges whether or not a competitive moving machine has acquires a energy wave transmitting right (121). When the competitive moving machine has not acquired the transmitting right, the traveling machine broadcasts the declaration of the acquirement of the energy wave transmitting right (122) and transmits the energy wave (123). When the competitive machine has acquired the right, the machine joins a transmission queue (125) and, whenever machine receives the declaration of the waiver of the energy wave transmitting right from other moving machines, the machine increases its priority in the queue.
