Inventor: HARADA TOYOJI
IPC: H02H3/28
Filed: 1998-07-16
Abstract: PROBLEM TO BE SOLVED: To surely judge current transformer(CT) saturation with a simple calculation by locking the judgment output of a digital relay by regarding that a rectifier CT has been saturated when it is judged that a certain difference data projects from the previous and the succeeding one at least by a specific difference or a specific ratio. SOLUTION: A central processing part 1 is provided with an auxiliary transformer 11 for inputting the detection current of a current transformer CT1 being installed at a terminal A and a sample holder 13 for sampling while dividing one cycle into a plurality of periods and also is provided with a transmission terminal device 20 for allowing the current of a terminal B from a terminal part 2 to appear. Then, the output of a current differential relay judgment part 16 and that of a CT saturation judgment part 17 enter a logic circuit part 18, thus driving an auxiliary relay 19 according to the result. Then, when the CT saturation judgment part 17 judges that the CT has been saturated, it locks the judgment of a current differential relay through a logic circuit part 18 and hence securely judging the saturation of the CT with a simple calculation and preventing malfunction.

Filed: 1987-08-13
Abstract: PURPOSE:To detect a position while reducing erroneous operation due to disturbance, by a method wherein a plurality of sonic wave receivers are arranged on the same plane so as to be spaced apart from each other by a definite distance and a pulse like sonic wave signal is transmitted from the transmitter moving on the surface known in the vertical distance from said plane and the difference between the times when respective sonic wave receivers receive the sonic wave at first is calculated. CONSTITUTION:A transmitter T1 is mounted on the unmanned vehicle 1 running on a floor surface and sonic wave receives S1-S3 are arranged to the ceiling having a height (h) from the transmitter T1 so as to be spaced apart from each other by a definite distance. Then, the transmitter T1 is driven for an arbitrary time by a tone burst wave signal to transmit a pulse like sonic wave signal. When the signal is received by either one of the receives, the receiving point of time is set 0 and the time difference until the other receivers receive the signal at first is measured by a time measuring means. Then, the relative positions of the transmitter T1 from a plurality of the receivers are detected. Therefore, without taking the synchronism of the transmission of the transmitter T1 and the reception of the receives S1-S3, the position of the transmitter T1 can be measured while erroneous operation due to disturbance is reduced.

Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To provide a power circuit with good efficiency, in which loss in power is drastically reduced by passing only a variation control factor through a power conversion circuit, and reducing the power to be converted. SOLUTION: When a voltage higher than a voltage of a power supply 1 is fed to a load, an output from a positive terminal Pa of a power conversion circuit 2 is negatively fed back to obtain a target voltage. A negative terminal Pb of a power conversion circuit 2 is connected to a positive terminal of the power supply 1, and these terminals have the same potential. Then, a short voltage with respect to the power voltage is generated by the power conversion circuit 2, and the total amount of voltages is fed to a load 3 (step A). When a voltage lower than the power supply voltage is fed, the feeding voltage from the power conversion circuit 2 to the load 3 is fed back negatively to obtain a target voltage, and the output terminals of the power conversion circuit 2 are connected to terminals with each polarity in the power supply (step B).  A lower voltage portion with respect to the power supply voltage is generated by the power conversion circuit 2 and is fed to the load 3. Then, the power obtained by reducing the voltage is fed back to the power supply, and thereby a loss in power is reduced.

Abstract: PURPOSE:To provide an electrically conductive material capable of imparting a synthetic resin, paint, adhesive, etc. with excellent electrical conductivity, by applying a metallic film to the surface of a hollow glass particle by electroless plating, thereby forming a uniform and tough film to each particle. CONSTITUTION:Hollow glass particles having an apparent specific gravity of <=1, an average particle diameter of preferably <=100mu (the finer, the better) and a sharp particle size distribution, i.e. so-called glass balloons, are sensitized by contacting with an aqueous solution of a soluble stannous compound e.g. by immersion or spraying, and then brought into contact with an aqueous solution of a soluble Pd salt in the same manner to effect the activation of the particle. The particles are dispersed in an queous medium, and an electroless plating liquid is added to the dispersion at a controlled rate of addition to effect a rapid plating reaction. A unifrom and tough metallic film is formed to the surface of the dispersed particle by this process. The thickness of the metallic film can be controlled by adjusting the amount of the plating liquid. Since the apparent specific gravity of the obtained particle is 0.4-2.0, the product can be used as an additive to impart high electrical conductivity to a synthetic resin, paint, adhesive, etc.

Title: Adhering plate peeling device
Inventor: ABE KOSUKE
IPC: G11B23/00
Filed: 1988-08-15
Abstract: PURPOSE:To perform the simultaneous peeling of a large number of adhering plates without generating damage on the plates by inserting an expandable and extendable cylinder into the inside diameter hole of the contact plate, expanding the cylinder so as to be adhered tightly with the inside diameter hole, and extending the cylinder set in the expanding state. CONSTITUTION:By expanding the cylinder 2 inserted into the inside diameter hole 1a of the plate 1 set in the expanding state, the cylinder 2 is adhered tightly with the plate 1, then, they are integrated. When the cylinder 2 is extended in such state, the plate 1 can be peeled individually since the plate 1 is displaced one by one according to the extension of the cylinder 2. Next, the plate 1 can be released from the adhering state with the cylinder 2 by restoring the cylinder 2 to an origin. In such a manner, it is possible to peel a large number of plates 1 simultaneously, and to prevent the plate 1 from being damaged in peeling.

Abstract: PURPOSE:To eliminate a difficulty for moving a line of sight by displaying, on a part of a display screen, a character or the like defined in the vicinity of an instructed coordinate when the character or the like defined on a coordinate panel is instructed. CONSTITUTION:A CPU21 switches a picture memory VRAM29 to an exchange memory SRAM32.

Abstract: PURPOSE:To prevent leak from a closed space by placing a pressure lead hole, opened to the inner face of the end plate of a fixed scroll or a turning scroll, in a position away from a spot in contact with the inner or outer diameter side of the fixed or turning scroll by the other lap width measure part or less. CONSTITUTION:A lap 12 erected on the inner face of the end plate 11 of a scroll, and the lap 22 of a turning scroll are meshed with each other, and a pressure lead hole 41 for communicating a closed space 24 with a back pressure chamber is opened to the inner face of the end plate 11.
