    摘要: To provide a method of synchronous circuit opening of generator circuit breaker and its control apparatus that can protect a sound generator system of a generator main circuit from a phenomenon that current may not pass through current zero for many cycles. There is provided a construction where a generator exciting current control is incorporated into a control mechanism. In case that an occurrence possibility of a phenomenon that current may not pass through current zero for many cycles can be anticipated, time delay is intentionally caused by timer so as to prevent synchronism of the phenomenon, using an output signal of a generator lock-out relay which covers individual element of an electrical fault causing the phenomenon or in which circuit all those elements are integrated. In case that the phenomenon can be anticipated by calculation, a reactive power output of a generator is increased and consequently AC current amplitude of a sound generator is increased so as to eliminate the phenomenon.

    摘要: A monitoring and control system is provided having a control device, arranged in a central controller room, which provides commands to power distribution panel switch gear located in the field. The switch gear transmits and receives controlling and monitoring signals through wireless communication applying an evanescent mode. The switch gear has a power circuit connected to a plurality of devices to be operated. The switch gear is a panel comprising metal and non-metal surfaces, so that a portion of wireless waves in the evanescent mode travel out of the panel. A receiver is provided for monitoring the wireless waves that travel out of the panel. The wireless signals are compared with information stored in a diagnostics database, and are diagnostically evaluated to determine whether the signals are within a known normal operating range.

    摘要: The present invention relates to an improvement of a discharge container with a nozzle for housing a liquid, for example, an instantaneous adhesive or another moisture curing type adhesive, various adhesives such as solvent volatilizing type adhesive, various chemicals, foods, inks and medical supplies. The present invention is a discharge container with a nozzle which includes a container body for housing contents, a nozzle threadly attached to the container body, and a dual-shoulder type protective frame having a neck hole, wherein the base end of the mouth of the container body is inserted through the neck hole of the dual-shoulder type protective frame, and the container body is threadly attached to the nozzle, thereby allowing them to be made a one-piece structure. The present invention is a highly safe and easy-to-use container which can house a relatively high viscosity liquid such as jelly-like and grease-like ones, be stood up, discharge the contents smoothly until before the last service, provide no liquid run and leakage, and discharge the contents completely until before the last service. Particularly, the container of the present invention is excellent in safety and operability such that the container is opened or closed through the protective frame without directly touching the container body, so that the tube when used is not deformed or broken until before the last service.
