Title: Multiprocess system provided with device for optimizing spin lock operation
Inventor: HAGERSTEN ERIK E
IPC: G06F15/173
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To optimize the operation of multiprocessor system under spin lock so as to decrease the number of transaction requests as a result of unlocking. SOLUTION: Even when a read-to-own(RTO) transaction request is received after a sort of read-to-share(RTS) transaction request is received by a processing node, in order to optimize performance during spin lock operation, a home agent preferentially processes the RTO transaction request rather than the processing of RTO transaction request. This is performed by providing a 1st queue, with which the RTO transaction request conveyed through a mutual connecting network is received, different from a 2nd queue for receiving the RTS transaction request inside the home agent.

Filed: 1982-11-29
Abstract: PURPOSE:To simplify a switch circuit and to prevent the generation of waveform distortion by inhibiting the ground-fault protection during ringing. CONSTITUTION:A signal which is same as a control signal of a switch S7 is applied to an inhibition control input IS. The control signal of the switch S7 corresponds to both ringing and silent state, the switch S7 is closed during the ringing, an inhibiting control input IS is applied to an inhibiting gate INH to prevent a ground-fault detecting output GDET from being applied to an internal resistance control circuit RCONT.

Title: Deterioration detecting method for zinc oxide type lightening arrestor
Inventor: SAKURABA YUKIYA
IPC: G01R31/00
Filed: 1988-08-23
Abstract: PURPOSE:To detect even the deterioration due to a simple cause by detecting the phase difference in leaking currents from a plurality of zinc oxide type lightening arrestors which are connected to multiple-phase AC circuits. CONSTITUTION:Leaking currents from lightening arrestors 2u - 2w are detected with current transformers 3u - 3w. The detected current signals from the current transformers 3u - 3w are amplified in amplifiers 4u - 4w and inputted into phase difference detecting circuits 5a - 5c. The circuits 5a - 5c detect the phase difference between the phases. The detected signals are inputted into a microcomputer 6. The computer 6 receives the detected signals of the circuits 5a - 5c, performs operations and judges the states of the lightening arrestors 2u - 2w. Since the deteriorations of the lightening arrestors are judged by using the phase difference in this way, the effect of the distortion in power source voltage is hard to receive. Therefore, not only the deterioration of the nonlinear resistance component of the zinc oxide film but also the deterioration due to simple causes such as hygroscopic deterioration can be detected.
