Title: Rotor of rotating electric machine
Inventor: OKI NORIHIRO
IPC: H02K3/48
Filed: 1993-06-16
Abstract: PURPOSE:To prevent electrolytic corrosions and cracks from being generated in a wedge for supporting a field coil in a slot, by forming through an atomic bond accompanied by diffusion the film made of an intermetallic compound which has a low frictional quality, an arc resistance and an electric conductibility on the outer peripheral surface of the metal of the base material of the wedge. CONSTITUTION:On the surface of the shoulder part of a wedge 4 to be inserted into the slot of a cylindrical rotor, the film made of an intermetallic compound 4a' is formed through an atomic bond accompanied by diffusion. This wedge film 4a' is made to have a low frictional quality regarding its insertion into a slot tooth and an arc resistance, and to have a wear resistance capable of resisting a very small oscillation caused by its sliding contact, and further, to be an electrically good conductor. Thereby, the current flowing through the wedge which is contacted mutually with the slot tooth and a damper can be made to flow smoothly. As a result, electrolytic corrosions or cracks can be prevented from being generated on the contacting surfaces of the wedge with the slot tooth and the damper.

Title: Controller for power plant
Inventor: KOBAYASHI YOSHIO
IPC: H02P1/58
Filed: 1977-12-05
Abstract: PURPOSE: To reduce the capacity and number of starting transformers, by appropriately controlling the order of starting of auxiliary appliances when each unit starts.  
     CONSTITUTION: When the controller 12 has received a starting instruction from a centralized control room 11, the controller judges on the ground of the capacity or secondary current of the starting transformers of the power plant whether or not the units corresponding to the starting instruction can start. If the units can start, the controller discriminates the order of starting of the ausiliary appliances and then sequentially starts the units while supervising the secondary current of the starting transformers. The secondary current of the staring transformers is controlled properly when there is a certain starting transformer capacity even if a starting instruction for sole starting, simultaneous starting or sequential starting is applied. As a result, a plurality of units can be started through a single starting transformer according to the judgement by the controller 12.

Title: File control system
Inventor: SUGIMOTO NAOYA
IPC: G06F12/00
Filed: 1988-06-13
Abstract: PURPOSE:To securely control the open state of a file even if the abnormality of power disconnection and the like occurs by setting the counter concerned of a counter table to zero, adding counters and setting an open time when the open time is earlier. CONSTITUTION:When the file 2 is opened, the open time of the file 2 in an open time table 5 is compared with the starting time of a computer system. When the open time is earlier, the counter concerned of the counter table 6 is set to zero and the counters are added, whereby the open time is set. Namely, the counter concerned of the counter table 6 remains in a state except for zero when the abnormality of power disconnection and the like occurs in a state that the file 2 is opened. But, the counter concerned of the counter table 6 is set to zero by comparing the open time of the file in the open time table 5 with the starting time of the computer system when the file 2 is opened at the first time after the computer system is re-started. Thus, the open state of the file can securely be controlled even if the abnormality of power disconnection and the like occurs.

Abstract: PURPOSE:To achieve non-contact detection of phase at one time in a 3-phase transmission/distribution line, by arranging a photoelectric field sensor using a Pockets effect element near the 3-phase transmission/distribution line. CONSTITUTION:Capacitor parallel that a electrodes 10 and 10' of a photoelectric field sensor are arranged right below the center of 3-phase transmission/ distribution lines A-C to receive a horizontal electric field being divided. Potential generated between the electrodes 10 and 10' is introduced to a Pockets effect element 11 with a lead 12 and subjected to an optoelectric conversion with a light waveguide through an E/O transducer 13 and an O/E transducer 14 to obtain an AC sine wave voltage component. In other words, when three wires A-C are arranged and a voltage applied thereto correspond to any one of VR, VS and VT, voltage are detected in six arrays of phases depending on the combination of application of voltages VR, VS and VT. Then, voltage phases detected are obtained by determining a phase reference to clarify which of the voltages VR, VS and VT is applied to each one of A-C wires. This enables detection of phases of applied voltages of the wires by extracting voltage components with a photoelectric field sensor.
