Title: Non-slip device for tire
Inventor: BABA TAKETSUNA
IPC: B60C27/06
Filed: 1991-12-04
Abstract: PURPOSE:To surely fix a locking body and a base plate upon inserting the protrusion of the base plate into the groove of the locking body. CONSTITUTION:A fan-like section 46B is arranged in the inlet section of the locking groove 56 of a locking body. The holding body 30 connected to the fan-like section 46B is provided with a locking claw 85, which is provided with a slant face 90. A disk section 18 is provided with a recessed section 24 adapted to contain the locking claw 85 therein, and an inclined block 88 is projected in the vicinity of the opening of the recessed section 24. The inclined block 88 is provided with an inclined face 88A in the side opposed to the inclined face 90 of the locking claw 85. The holding body 30 is energized by a compression coil spring in a direction to let the locking claw 85 enter the recessed section 24. Since the holding body 30 is energized by the compression coil spring, and as a result, the locking claw 85 abuts on the inclined face 90 of the inclined block 88, if the operator set the holding body free, the fan-like section 46B can surely return to the inlet section of the locking groove 55. Therefore, the projection of a base plate can be surely held in the locking groove 55.

Title: Detection of fault section for power cable
Inventor: AMANO KAZUO
IPC: G01R31/08
Filed: 1987-12-18
Abstract: PURPOSE:To enable detection of a fault section in details, by measuring fault currents in a batch as flowing through conductors and sheaths of cables of respective phases to compare the section involved with an adjacent section. CONSTITUTION:Currents at a fault flowing through conductors 22 and sheaths 24 of cables 20 of respective phases are measured in a batch with CTs 51-56 among connection boxes 31-36 and the results of measurement are compared with the current of an adjacent section. Here, measurement in a batch means obtainment of a vector sum of fault currents in the conductors 22 and the sheaths 24. For example, when a ground fault occurs at a fault point 66 between the connection boxes 33-34 in a phase A, a conductor current I and a sheath current (i) are flowing inverted in phase by 180 deg., bringing measured values thereof to zero. This indicates that a fault occurs in a section giving zero.

A 2nd impedance conversion circuit 24 converts an absolute value of a reflection coefficient of a 2nd external circuit 3 so as to be equal to an absolute value of a reflection coefficient for frequencies f1, f2 of the circuit 1 converted by the conversion circuit 21. Distributed constant lines 22, 23 convert a phase angle theta so as to be shifted to a complex conjugation position of the impedance. As a result, each impedance at frequencies f1, f2 converted by the circuits 21, 24 has a conjugate relation and then matched with each other. Thus, even when the impedance of one of the external circuits depends on the frequency, the impedance is matched.

Filed: 1990-11-27
Abstract: PURPOSE:To decrease the burning of a cathode-ray tube by constituting the display controller so that when an inversion occurs, a display of a display device is turned on or off. CONSTITUTION:The display controller is constituted of an inversion detecting circuit 1-1, a CPU 1-2, and a DISP (display driving) signal control circuit 1-3. In such a state, by controlling a driving signal of a display device by an inversion of a telephone circuit in order to extend a service life of the display device, the display is erased at the time when it is unnecessary, and the display is executed at the time when it is necessary (the polarity of the telephone circuit is inverted). In such a way, since the display of the display device is turned on/off by utilizing the inversion of the telephone circuit, burning of a cathode- ray tube can be prevented.

Also, a second valve element 34 is also energized by a spring 29 and is brought into contact with a second valve seat 37, so that a bypass channel 36 is disconnected. Here, when a small flow is exhausted, a first port 15 is pressurized, thereby pressure of a first pressure chamber 13 is increased, and a valve piston chamber 32a is also boosted. Then, a valve piston 32 is downwardly moved against the energization force of a spring 42. The second valve element 34 is separated from the second valve seat 37 against the energization force of the spring 29 through a diaphragm 40 and a valve button 38. Then, the small flow is exhausted through a bypass passage 36 and an orifice member 4.  The flow is determined by orifice diameter, and can be exchanged. Even through valve opening/closing action is increased, a constant flow can be continuously maintained.
