Title: Reduction for residual grounding voltage in high voltage system
Inventor: WASHIO KOJI
IPC: G01R31/12
Filed: 1988-04-15
Abstract: PURPOSE:To achieve a reduction in a residual grounding voltage by connecting a capacitor to a high voltage side terminal in a three-phase start fashion to close the capacitor between a neutral point thereof and the ground after the closure of a high voltage breaker. CONSTITUTION:A capacitor 15 connected in a three-phase start fashion is connected to a high voltage terminal of a main reactor 3 and built into a reactor device. A low voltage breaker 16 is connected between a neutral point of the capacitor 15 and the ground. When the breaker 16 is opened to close a high voltage breaker 2, the neutral point of the reactor 3 is shifted to a high impedance connection with respect to the ground with ground current suppression circuits 4-6. When the breaker 16 is closed, the neutral point of the capacitor 15 is connected to the ground and an electrostatic capacitance enters a zero- phase circuit and connected in parallel to a capacitor 14 of a high voltage system, causing an increase in the electrostatic capacitance of the high voltage system. This results in a decrease in a ground residual voltage thereby enabling accurate diagnosis of deterioration in insulation with a reduction in residual grounding voltage.

Title: Pressure discharger for oil-filled electric apparatus
Inventor: KON KAZUO
IPC: H01F27/02

Abstract: PURPOSE:To prevent generation of rust in a pressure discharging pipe by a method wherein an oil piping to communicate between the upper part and the lower part inside of an oil-filled electric apparatus, and moreover, at least a part thereof passes the inside of the pressure discharging pipe is provided, and cooling oil inside of the oil- filled electric apparatus is made to circulate in the oil piping. CONSTITUTION:At the inside of a transformer main body 1, electric energy of no-load loss, load loss, etc., is converted into heat energy to make the temperature of cooling oil filled up inside to rise. The cooling oil whose specific gravity is lightened according to temperature rise ascends to the upper part inside of the transformer main body 1, and flows in the oil piping 12 set up inside of the pressure discharging pipe 2 passing through the oil piping 11 at the upper part. The cooling oil flowed in inside of the oil piping 12 thereof is cooled by itself to make specific gravity to heavy by making the low temperature of air in the pressure discharging pipe 2 to rise, and descends in the oil piping 12 to return inside of the transformer main body 1 from the oil piping 11 at the lower part, and above-mentioned cycle is repeated. Accordingly because temperature in the pressure discharging pipe 2 is held high by the cooling oil of the transformer main body 1, and relative humidity in the pressure discharging pipe can be suppressed low even when high temperature high humidity air invades from an oil pit 5, dew condensation is not generated.

Abstract: PURPOSE:To store at least character information of a single page in memory and allow reprinting as many times as required by simple procedures by providing an instruction device to instruct reprinting of characters in accordance with character information to be stored in memory and a reprinting device to reprint characters in response to the character information. CONSTITUTION:Reprinting is realized by sequentially increasing the value of a pointer BP from the lowest-order address of a memory area to the highest- order address, and sequentially reprinting characters stored in an address indicated by the point BP. First, the value of the BP is increased so that the BP indicates the initial data stored in the memory area. Next, if the value of the pointer BP is larger than the value of a work pointer BP2, the value is detected to complete the reprinting. However, if the value of the pointer BP is smaller than or equal to the value of the work pointer BP2, the reprinting is continued. The stored character code is read from the address indicated by the pointer BP, then the value of the BP is increased so that a next character code is shown and characters corresponding to the character code which has been read are printed.

Title: Cr filter circuit
Inventor: OI MASUMI
IPC: H03H7/06
Filed: 1989-04-13
Abstract: PURPOSE:To enlarge the dynamic range of an input level by installing a first capacitor and a second capacitor, where the input signal voltage dependency of capacity values come to a mutually opposite relation. CONSTITUTION:Two capacitors 4 and 6 consisting of PN joining capacities are connected to an output terminal 2. The N-area side of the first capacitor 4 is connected to the output terminal 2, and a DC voltage source 5 for impressing a bias V1 is connected to the P-area side. On the other hand, the P-area-side of the second capacitor 6 is connected to the output terminal 2, and a DC voltage source 7 for impressing a bias V2 is connected to the N-area-side, whereby it is assumed to be V1<V2. Consequently, the input signal voltage dependency of the capacity values of two capacitors 4 and 6 comes to the mutually opposite relation, and a range where the input signal voltage dependency hardly exists can be obtained for a wide range as to the whole capacity values. Thus, a cut off frequency does not change in accordance with the input signal level, and the dynamic range of the input signal level is enlarged.
