摘要： PROBLEM TO BE SOLVED: To provide a gas insulated switchgear in which a shut-out period of a cable is short at inspecting/repairing a power receiving shielding device, for safe inspection/repair of the power receiving shielding device. SOLUTION: The gas insulated switchgear is provided with a cable temporary placement facility to which a cable is attached at repairing/inspecting a power receiving shielding device which is housed in a tank in which an insulating gas is sealed up and receives power supply through the cable. A cable shut-off period is significantly reduced because the cable shut-off period is only for attaching/detaching operation of a cable before and after the start of operation.

摘要： PURPOSE:To perform the storage, extraction and arithmetic processing of data at a high speed by storing the data to be calculated via a stack and at the same time setting a stack pointer at +1 and -1 in the storing and extracting instruction cycles of the data. CONSTITUTION:A stack STC consists of plural continuous registers S0-Sn and connected selectively to a pair of data buses BA and BB via gate circuits G1 and G2 which are controlled by control signals C1 and C2 respectively. One of those registers S0-Sn is designated by a stack pointer SP is connected to the bus BA or BB via the circuit G1 or G2. The pointer SP performs an increment action of +1 in a machine cycle of a data storing instruction and then an increment action of -1 in an extracting instruction cycle respectively by a control signal C5.

摘要： PURPOSE:To improve a program executing speed by providing a field for containing the attribute of a method, such as a physical address, etc. of an executing code of a method to be called, in a method cache, so that when the method which is called once is called again, the executing code can be read out directly and executed. CONSTITUTION:In consideration of the locality of a program, as for a method which is called once, an attribute of its method is contained instead of a method handle and a primitive index, in the third and the fourth areas of each field in a method cache MC. In such a case, a the attribute of the method signifies, for instance, a physical address instruction address for showing an address in which a code of an instruction to be executed in the next time is contained, and a physical address (head address) for indicating the address of head part of the method. As for the method which is called once, a physical address for indicating its executing code is contained in the method cache MC, therefore, in case of searching its method again, the method to be derived can be called immediately by subtracting the method cash MC by a hash value.

摘要： PURPOSE:To execute at a high speed a procedure call and a reference of a variable, etc., by providing a frame pointer group for indicating each base position, and also providing a context pointer, with respect to plural activation records which are allocated onto a large capacity register. CONSTITUTION:An activation record is made to correspond in accordance with the order of each word FP0, FP1...FPn in a frame pointer group FP for showing a base position of each area of activation records AR0, AR1...ARn which are allocated onto a register file RF, and the activation record is allocated efficiently without generating a null area in the register file RF. Also, this device is provided with a context pointer CP for indicating a frame pointer FRi for showing a base position of the activation record ARi which is formed in accordance with a procedure which is being executed at present. In such a way, switching of the activation record by a procedure call can be realized by only changing a value of the context pointer CP.

摘要： PROBLEM TO BE SOLVED: To solve the problem that operating efficiency is extremely low in an insulated switchgear due to the fact that: since the frequency of delivery of a breaker of a transformer to an electric railroad company is high while a breaker of a receiving unit is less often in delivery thereto, and when the number of operations of the breaker in high delivery frequency reaches a prescribed number, the breaker in high delivery frequency is subjected to an inspection after being removed, and then repaired or replaced to a new one, thus causing a long time stop of an apparatus for the removal of the breaker in high delivery frequency, and further causing the breaker less often in delivery substantially not to operate. SOLUTION: When a load-side breaker 13 is at the stage of an inspection in the number of closings and breaking thereof, a cable head 19 of the load-side breaker 13 is connected to a cable head 3 of a power-side breaker 9 and the cable head 3 of the power-side breaker 9 is connected to the cable head 19 of the load-side breaker 13, thereby largely reducing a time for maintenance and inspection and also improving the operating efficiency of the breaker.

摘要翻译：要解决的问题：为了解决绝缘开关设备中的操作效率极低的问题，由于以下事实：由于变压器的断路器向电气公司的输送频率高，而断路器接收单元的传送次数较少，当高传送频率的断路器的操作次数达到规定数量时，高传送频率的断路器在被去除之后经过检查，然后被修理或更换为因此导致长时间停止用于以高输送频率去除断路器的装置，并且进一步使得断路器在输送中的频率不会基本上不起作用。解决方案：当负载侧断路器13处于关闭和断开次数的检查阶段时，负载侧断路器13的电缆头19连接到电源侧断路器13的电缆头3。侧断路器9和电源侧断路器9的电缆头3连接到负载侧断路器13的电缆头19，从而大大减少了维护和检查的时间，并且还提高了断路器的操作效率。版权所有（C）2004，JPO

摘要： PURPOSE:To reduce the size of an enclosure for a circuit breaker by housing a current transformer through an insulation spacer in a dedicated enclosure, disposing an enclosure housing the ground switches at the opposite ends of an interrupting section on one end face of the enclosure for circuit breaker, and setting the operating direction of the mover in the ground switch in parallel with that of the mover at the interrupting section. CONSTITUTION:A current transformer 7 is housed through an insulating spacer 15 in an enclosure dedicated for a circuit breaker. An enclosure 25 housing the ground switches 5a, 8a at the opposite ends of an interrupting section in parallel is disposed on one end face of the enclosure 16 for the circuit breaker. The operating direction of mover in the ground switch 5a, 8a is set in parallel with that of mover at the interrupting section. A switch control box 14 is disposed on the base 18 of gas insulated switchgear thus reducing the height and size of the enclosure 16 for the circuit breaker. This structure enhances the measurement accuracy of current transformer and reducing the installation space thus enhancing the maintenance and inspection performance.

摘要： PURPOSE:To obtain a tank arrester having high reliability by bypassing surge current to an arrester container with an operation counter so that steep surge current does not flow to a grounding conductor. CONSTITUTION:An operation counter 2 and a recorder 3 connected to a grounding conductor 5 in parallel are connected to an arrester container. Even if a steep thunder surge current enters an arrester, it is bypassed to the arrester container through a non-linear resistor 7 in the operation counter 2, and earthed to a grounding conductor of the arrester container. If the arrester 1 is broken by thunder attack, ground current does not flow to a operation counter 9 having large resistance and flows to the grounding conductor to prevent the breakage of the operation counter 9. The tank arrester having high reliability is obtained.
