Title: Secondary exciting control method for ac excited synchronous machine
Inventor: YOKOTA HIROSHI
IPC: H02P9/04
Filed: 1993-10-20
Abstract: PURPOSE:To alleviate vibrations of an AC excited synchronous machine and a pump water wheel, to increase their lives and to deal with instantaneous input and output increase/decrease command within an allowable variable speed operating range by suppressing increases in the numbers of revolutions of the machine and the wheel at the time of shutting OFF a load. CONSTITUTION:Energy of water flow input to a pump water wheel 10 is regenerated by regenerating an exciting converter at the time of shutting OFF a load at the time of generating until guide vanes are fully closed, and an increase in the number of revolutions of an AC excited synchronous machine 100 is suppressed. When the present number of revolutions is abruptly changed to required input/output of a power system, power abrupt change rate is so calculated by an input/output rate setter as to fall within an allowable variable speed operating range, and the machine 10 deals with instantaneous input and output increase/decrease command.

IPC: F25B9/14
Filed: 1988-10-18
Abstract: PURPOSE:To minimize the amount of heat which is conducted to a low-temperature chamber through the cylindrical part of a low-temperature cylinder, and to improve a refrigerating efficiency by a method wherein the low-temperature cylinder is made of an alloy which is produced by containing specified amounts of aluminum and vanadium, or aluminum and tin, respectively, in titanium. CONSTITUTION:The amount of heat, which is conducted from a high-temperature chamber 17 to a low-temperature chamber 16 through the cylindrical part of a low- temperature cylinder 14, is minimized to improve a refrigerating efficiency. That is, the cylindrical part of the low-temperature cylinder 14 is made of an alloy which is produced by containing 6% of aluminum and 4% of vanadium in titanium having high hardness and low thermal conductivity, of by containing 5% of aluminum and 2.5% of tin in titanium. Since such an alloy as mentioned above is used for the cylindrical part of the low-temperature cylinder 14, the wall thickness of the cylindrical part of the low-temperature cylinder 14 can be made thinner. Further, since the material itself has low thermal conductivity, the amount of heat, which is conducted from the high-temperature chamber 17 to the low-temperature chamber 16 through the cylindrical part of the low-temperature cylinder 14, can be minimized.

Title: Prevention and elimination of oxygen-poor water mass by lime material
Inventor: IWASHITA TETSUSHI
IPC: C02F1/00
Filed: 1990-10-03
Abstract: PURPOSE:To control the oxygen consumption and prevent the occurrence of an oxygen-poor water mass by dispersing the lime material capable of existing in water as calcium hydroxide or magnesium hydroxide uniformly in a predetermined water area. CONSTITUTION:The lime material capable of existing in water mainly as calcium hydroxide or magnesium hydroxide is dispersed uniformly in the water areas. A mere periodic dispersion of the lime material in the water areas controls the oxygen consumption, prevents the occurrence of oxygen-poor water mass and improves and eliminates the oxygen-proof water mass occurred. A uniform dispersion of the lime material produces a difficulty soluble film consisting of calcium hydroxide and calcium carbonate in a fresh water area, a difficulty soluble film consisting of calcium hydroxide, calcium carbonate and magnesium hydroxide in a sea area and both of the aforesaid films in a brackish water area. The film formed on the bottom sediment cuts off the communication of the water with the bottom sediment, thereby preventing the oxygen in the water from passing into the bottom sediment.

Title: Audio response type wireless remote control transmitter
Inventor: TAKAYAMA NORITSUGU
IPC: H04Q9/00
Filed: 1990-10-01
Abstract: PURPOSE:To prevent a wireless remote control transmitter from being dissipated by providing a means which generates audible sound replying to sound except for constant time when a key operation is performed at the transmitter. CONSTITUTION:When the sound, for example, by hand clapping or a whistle is emitted, a sound input detecting part 4 detects it, and outputs a detection signal to a control part 5. The control part 5 operates a sound output part 6 for the constant time by the detection signal, and issues the audible sound from a sounding body. Thence, when a remote control pulse is generated from a remote controller main body, a control signal to stop the operation of the sound output part 6 for the constant time is generated in spite of the presence/ absence of the sound detection signal. By providing the means which generates the audible sound replying to the sound at the wireless remote control transmitter shown in the above example, and the means which stops the audible sound while the remote controller is operated, it is possible to prevent the remote control transmitter from being dissipated.
