Abstract: PURPOSE: To provide a plant water processing control system capable of sufficiently controlling corrosion of heat conduction pipes. CONSTITUTION: Primary cooling water heated in reactor pressure vessel 1 is supplied to heat conduction pipes 4 of steam generators 3. Secondary water W2 in the steam generator 3 contacts the outer surface of the heat conduction pipes 4 and is heated to be steam, by which a turbine system 11 is driven. Part of primary cooling water is introduced in a corrosion electric potential measuring system 31, and part of the secondary cooling water is introduced to a corrosion electric potential measuring system 32 to measure the corrosion potentials of materials (same or equal material as the heat conduction pipes 4) dipped in those water. A computer 33 calculates the difference of electric potentials (driving force of corrosion) between two corrosion potential.  When this electric potential difference exceeds a specific value, water processing control system 34 and 35 are driver to suppress the electric potential difference within a specified value.

Abstract: PURPOSE:To make it possible to separate and detect external noises and partial discharge at the outside of a cable by individually inputting pulse shaped voltage waveforms induced at both ends of the cut parts of a cable shielding layer into the input layer of neural network. CONSTITUTION:One end of a power cable 2 is connected to a transformer 1. A shielding layer 5 for the cable is cut at a point C. Detecting elements 3 and 4 are connected to both cut ends. Pulse-shaped voltage waveforms induced at points A and B at both ends of the elements 3 and 4 at both cut end parts are inputted into two input layers 10 and 20 of a neural network. The pulse- shaped voltages are compared at intermediate layers 30 and 40, and the partial discharge at a cable 2 and the partial discharge at the outside of the cable 2 and external noises are distinguished. Therefore, the external noises and the partial discharge at the outside of the cable 2 are not erroneously recognized as the partial discharge in the cable 2.

Title: Continuous impact working machine
Inventor: YAMADA SAKUJI
IPC: B25D9/10
Filed: 1991-04-19
Abstract: PURPOSE:To prevent a vibration being produced at operation from being adversely affected to an engine or engine mounting part by making an operating pipe free of expansion as long as the specified length, and installing such a spring as energizing this pipe in the extending direction at all times. CONSTITUTION:This machine is interposed between an impact generating mechanism 2 and an engine 5. An operating pipe 4, inserting type in a transmission shaft 9, is made free of expansion as long as the specified length as being energized by a spring 45 in the expanding direction. In addition, an operating handle being held by an operator is installed at a base end side of this operating pipe 4, namely, in a member to be situated at the side of the engine 5. Accordingly, when impact operation is performed by way of pressing the whole working machine to the tip direction as holding this operating handle, the operating pipe 4 is shortened as compressing the spring 45, so this spring 45 is balanced in a state of being compressed as far as the specified value. With this constitution, even if the impact generating mechanism 2 produces a vibration in the axial direction of the operating pipe 4, suchlike vibration is absorbed by this spring 45, thus it is not directly transmitted to the engine 5.

Title: Controller for permanent magnet polyphase synchronous motor
Inventor: MATSUOKA KAZUMASA
IPC: H02M7/48
Filed: 1994-05-30
Abstract: PURPOSE:To alleviate the torque pulsation of a synchronous motor and to prevent the decrease of its efficiency by controlling the gate of a single phase PWM inverter based on a second voltage command of a deviation from a first voltage command and a carrier having a predetermined peak value. CONSTITUTION:An induced voltage by a self-inductance or self and mutual inductances is calculated by differential circuits 1011-101n based on load current detected values If1-If3 of the respective phases. A second voltage command epsilonv of a deviation from a first voltage command is calculated by an adder 16. The command epsilonv is that in which a current distortion due to its inductance is removed. The gate of a single phase PWM inverter is controlled by a gate control circuit 20 based on the command epsilonv and a carrier having a predetermined peak value. Thus, the influence of the distortion due to the inductance is removed. The torque pulsation generated in a permanent magnet polyphase synchronous motor can be alleviated, and the decrease of its efficiency can be prevented.

Filed: 1994-05-31
Abstract: PURPOSE:To provide an efficient air conditioner wherein the output voltage- frequency characteristic of its inverter can be held in a predetermined one even when the load of its air compressor changes CONSTITUTION:By an AC current sensor 23, the motor current value of a compressor 1 is sensed, and by an AC current-voltage converter 24, the motor current value is converted into the internal voltage drop quantity of a DC power supply which is configured out of a AC-DC converter 16. By a voltage computer 25, the output DC voltage value of the DC power supply is computed, based on the voltage drop quantity. Based on the output DC voltage value, one of a plurality of waveshape patterns memorized previously in a waveshape memory 27 is selected by the voltage computer 25, and it is indicated to a waveshape generator 26. Based on the waveshape pattern, the waveshape signal for driving an inverter 19 is generated by the waveshape generator 26. The waveshape pattern is changed responding to the DC power supply voltage, and thereby, even when the load of the compressor 1 changes, the inverter 19 is driven efficiently while its output voltage-frequency characteristic is held in a predetermined one.

Title: Time division digital moving radio communication system
Inventor: AOKI MASATOSHI
IPC: H04J3/06
Filed: 1997-05-07
Abstract: PROBLEM TO BE SOLVED: To distribute load on all moving stations executing communication by switching moving stations (clock masters) emitting a synchronous radio wave at prescribed timing at the time of executing communication between moving stations. SOLUTION: A clock master gives a switching request to moving stations in a slave mode (S52) when a station in use satisfies the condition that a clock master witching request can be transmitted because of deterioration of capability as a clock master (S51). Then, in response to the switching request, a moving station in the slave mode, which satisfies the condition of a clock master switching response transmission and has the maximum capability as a clock master, makes response to the switching request (S56 and S57). Thus, the present clock master becomes a moving station in the slave mode (S54) and the moving station in the slave mode becomes a new clock master (S58).
