Title: Fault point locator for overhead transmission line
Inventor: HASHIMOTO MAKOTO
IPC: G01R31/08
Filed: 1989-10-12
Abstract: PURPOSE:To enable mounting and inspection without stopping power transmission with a higher locating accuracy by locating a fault point based on a time difference of a detection signal from a plurality of surge detection sensors set separated in a direction of a line of an overhead transmission line. CONSTITUTION:Surge detection light signals outputted from magnetic field sensors 60 set on steel towers T separated from a power line 50 are sent to a discriminator 70 through an optical fiber 66. The device 70 sends a time difference light signal between the moment when a surge detection light signal of a sensor 60 which detects a first surge is received and the moment when a signal of the sensor 60 which detects a surge afterward to a central processing unit 71 through an optical fiber compound overhead ground wire (OPGW) 51 to locate a point where a fault is generated based on a time difference. Thus, as the sensor 60 is set separated from the power line, mounting, inspection and the like of the sensor 60 are possible even under a hot line. This also enables catching of a change in space magnetic field thereby achieving a higher locating accuracy of a fault point with an accurate detection of surge.

Filed: 1999-09-17
Abstract: PROBLEM TO BE SOLVED: To obtain a reproducing circuit for MR head capable of holding an MR head at the grounding potential without connecting to the grounding potential and capable of preventing the dielectric breakdown by setting a bias voltage using a current source. SOLUTION: A current i2 supplied to the terminal ND2 of the MR head RMR is controlled by a voltage bias circuit 10 in accordance with a reference voltage VR supplied by a constant voltage source VS1 so that a terminal voltage ΔV of the MR head RMR is controlled to be nearly equal to the reference voltage VR.  A current i1 supplied to a terminal ND1 of the MR head RMR is controlled by a potential setting circuit 20 to hold a potential of a middle point of the MR head RMR to a nearly grounding potential GND, then a resistance value of the MR head RMR is changed in accordance with the recording information at the time of reproduction, and since the change of the terminal voltage according thereto is amplified by an output circuit 30 and outputted, the potential of the middle point can be held to the grounding potential GND without grounding the MR head RMR, then the breakdown due to the static electricity is prevented.

Filed: 1993-10-22
Abstract: PURPOSE:To prevent the proper wait time of a processing unit to be monitored from being defined as the target of monitor time by correcting the monitor time corresponding to the proper wait of the processing unit when that wait time is generated. CONSTITUTION:Inside an on-line controller 1, plural jobs are parallelly executed but the plural jobs can not simultaneously update a shared data base 3. Then, the maximum value of the lapse of time from the start of processing to the end (the monitor time) is decided for each of processing not to simultaneously execute the plural jobs inside a relational data base 5, when there is any job not completely processed even after the lapse of the monitor time, the generation of abnormality is decided, and waiting job processing is forcedly finished. In the case of proper wait, however, the monitor time is prolonged by adding the proper wait time before and after processing to be turned to proper wait. Concerning the job processing not to be finished even after this monitor time, it is detected by timer management 7 of the relational data base 5.

Title: Temperature compensation crystal oscillator
Inventor: KIKUCHI AKIRA
IPC: H03L1/02
Filed: 1989-10-12
Abstract: PURPOSE:To attain miniaturization and low power consumption by providing a DC conversion means converting temperature information into another temperature information having a polygonal line characteristic approximating a frequency temperature characteristic of a voltage controlled crystal oscillator, and sending the resulting information to a control voltage means. CONSTITUTION:A DC conversion means 3 is provided between a temperature sensor 11 and a control voltage generating means 4, converts temperature information proportional to a temperature change outputted from the temperature sensor 11 into temperature information having a polygonal line characteristic approximated to a frequency temperature characteristic of a voltage controlled crystal oscillator 15 and the information is fed to the voltage controlled crystal oscillator 15 as a control voltage. Since a change in the temperature information is large when the frequency change with respect to a minute temperature range  T is large and the change in the temperature information is small when the frequency change with respect to a minute temperature range  T is small, only nearly required temperature information is fed to the control voltage generating means. Thus, miniaturization and low power consumption are attained.

Title: Secondary battery
Inventor: KUBOTA TADAHIKO
IPC: H01M50/417
Filed: 1991-09-18
Abstract: PURPOSE:To provide a secondary battery by which a bath quantity is hardly decreased by carrying out graft polymerization on a monomer under a base body existent condition after plasma processing is carried out on the porous high polymer base body, and using the obtained high polymer base body as a separator. CONSTITUTION:A porous high polymer base body such as polyethylene or polypropylene is used as a base body. A porosity is set to be 40-90%, and an aperture is set to be about 0.01-5mum. A monomer contains a group dissoluble in electrolytic solution as expressed by formulae I-III. After plasma processing is carried out on the base body, graft polymerization is carried out on the monomer. According to this method, since a high polymer film is introduced effectively onto the surface of a high polymer base material, the separation with the lapse of time or by such a reason as a various kinds of processings or the outflow due to dissolution is hardly caused, so that the performance is never deteriorated. By selecting polymerizing conditions (such as a temperature, a time, a temperature of the monomer or a quantity of an interfacial active agent), thickness of a polymerizing layer can be controlled optionally from an extremely thin film to a thick film. Damage inflicted on the base material in a film forming process is so small that characteristics of the base material in itself are hardly spoiled. Since this film is used as a separator, a secondary battery, which has excellent charging/discharging characteristics and by which an internal short circuit or dendrite is hardly caused, can be provided.

Filed: 1994-10-06
Abstract: PURPOSE: To surely prevent an electric motor from abnormal heating and the like by providing a limiting means limiting the maximum value of a control signal according to the integrating value of the absolute value of the control signal. CONSTITUTION: A control signal driving a motor 12 based on the steering torque detected by a torque sensor 3 is formed by means of a microcomputer 21, and an H bridge circuit 40 is operated based on this so as to control the current carrying direction and the current carrying quantity to the motor 12.  Namely, by limiting the maximum value of the control signal according to the integrating value of the absolute value of the control signal to a motor drive circuit 30, for example, by limiting the control signal to be small in the case of the large integrating value of the absolute value of the control signal, or by enlarging the maximum value of the control signal reversely in the case of the small integrating value, the maximum value of the control signal is limited according to the integrating value of the control signal even in the case of the large steering torque and large current carrying to the motor 12. Consequently, generation of abnormality such as abnormal heating of the motor 12 following continuous large current flow can be surely prevented.
