    摘要: An evaporative fuel-processing system for an internal combustion engine includes a canister for adsorbing evaporative fuel generated in the fuel tank, a charging passage connecting between the canister and the fuel tank, a purging passage connecting between the canister and the intake system of the engine, an open-to-atmosphere passage for communicating the canister with atmosphere, a charge control valve for selectively opening and closing the charging passage, a purge control valve for selectively opening and closing the purging passage, and a vent shut valve for selectively opening and closing the open-to-atmosphere valve, and a pressure sensor inserted in the charging passage at a location on one side of the charge control valve closer to the fuel tank, for detecting internal pressure within the charging passage. When predetermined conditions are satisfied, the purge control valve is closed and the charge control valve and the vent shut valve are opened. It is determined that the vent shut valve is abnormal when the internal pressure detected by the pressure sensor is below a predetermined negative pressure value while the purge control valve, the charge control valve, and the vent shut valve are in the above respective states.

    摘要: A vacuum circuit breaker comprising an external coil which is arranged outside a vacuum interrupter, and a power supply circuit which causes current to flow through the external coil. An overcurrent flowing through the main circuit of the circuit breaker, which leads to a load, is detected by an overcurrent tripping device so as to separate the movable electrode of the vacuum interrupter from the fixed electrode thereof and to subject a striking electric arc to a magnetic flux generated axially of the vacuum interrupter by the electrodes themselves. Thereafter, a trigger gap is ignited by a signal delivered from the overcurrent tripping device, so as to introduce a reverse current into the vacuum interrupter. Herein, the trigger gap is ignited by a signal delivered from the overcurrent tripping device, in order that the zero point of currents may be formed at the point of time at which the axial magnetic flux has been canceled by the resulting current of the external coil. Since the axial magnetic flux remaining at the zero point of the currents is nullified, charged particles are not hindered from diffusing radially of the vacuum interrupter, and hence, an enhanced breaking performance is attained.

    摘要: In order to improve the rapidity with which an automatic equalizer can be pulled in when transmitting data at high baud rates, each of the modems of secondary stations are arranged to detect the divergence of the automatic equalizer included therein and induce the issuance of a tone signal which is supplied to the primary station and induces the latter to reissue a training signal. The automatic equalizers in the secondary stations pull in on the training signal which ceases to be issued when the tone signal is no longer generated.

    摘要: A coil case with a coil receptacle for receiving a coil winding is formed integrally with cover flaps which are swingably joined to either end of the coil receptacle by hinge portions. The coil case has mounting pawls formed thereon. The coil winding is received inside the coil case and the cover flaps are closed, whereby a leakage magnetic field cancellation coil is assembled. The cancellation coil is mounted onto the deflection yoke by engaging the mounting pawls with a part of the deflection yoke. Since the coil case and the cover flaps are formed integrally with each other, the number of component parts is reduced, thereby facilitating manufacture. Further, the size of the cancellation coil is reduced, thereby reducing the material costs, hence, the production costs of the apparatus. Since the cancellation coil can be mounted onto the deflection yoke by a single-step operation utilizing the mounting pawls, the efficiency of the mounting operation is improved.
