Title: Inertial rotation information detecting method and device for ac motor, and motor driving method
Inventor: ASAKAWA SHIYUUYA
IPC: H02P27/06
Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To provide a method and a device which can detect the direction during inertial rotation easily. SOLUTION: An induction motor 4 is driven by an inverter circuit 3, and the switches Q2 , Q4 , Q6 of the inverter circuit are turned on simultaneously to detect a rotation direction during subsequent inertial rotation, thus keeping a zero vector control condition. Current is detected by current detectors 6, 7 for peak detection of them. By making phase comparison for them, normal rotation is discriminated from reverse rotation for detection. If a reverse rotation command to the normal rotation occurs with the normal rotating detected, the output frequency and voltage of an inverter at this point are controlled for smooth shift to reverse rotation.

Title: Skull melting furnace and production of high purity alloy using it
Inventor: HANAMURA TOSHIHIRO
IPC: B22D11/06
Filed: 1997-03-05
Abstract: PROBLEM TO BE SOLVED: To ensure overheating of molten while preventing contamination from a crucible by applying ceramics lining to a water cooled copper segment and providing an opening/closing ceramic cover. SOLUTION: A water cooled copper segment 2 constituting a water cooled copper firth 1 is lined with ceramics 7. Yttria or calcia is preferably employed as ceramic because of low reactivity but alumina maybe employed satisfactorily because it is cooled by touching the water cooled copper herth 1. Magnecia is not preferable because it react strongly on a molten. Lining is applied only between slits while taking account of balance between thermal insulation and cooling. A columnar ceramic cover 8 is fixed while being spaced apart slightly from the water cooled copper firth 1 and suspended by means of a ceramic rod 12 in order to ensure overheating without confining heat. According to the structure, a high purity molten alloy can be produced while ensuring high overheating and suppressing contamination from the furnace.

Abstract: PURPOSE:To intermittently perform remote control signal reception and reduce the power consumption of the remote control signal reception system by controlling a power source means by a power source control means unless a remote control signal is inputted to the remote control signal reception system. CONSTITUTION:A sent signal is sent from a remote control signal transmitting circuit 1 with infrared rays, which are photodetected by a remote control receiving circuit 2 and converted into an electric signal.

The selected remote control signal is decoded by a decoding circuit 4 and held by a latch circuit 5. When the remote control signal discriminating circuit 3 does not recognizes the input of the remote control signal, a power source control circuit 6 controls a power source circuit 7 to places the remote control signal receiving circuit 2 in intermittent operation. Thus, the remote control reception system operates intermittently unless the remote control signal is inputted to reduce the power consumption.
