摘要:
An improved overcurrent automatic prevention apparatus having an individual fault display and permanent ground functions capable of automatically detecting whether overcurrent flows to a switch, which occurs due to a short of communication cables and properly limiting the overcurrent flow thereto, and when overcurrent exceeding a threshold value continuously flows thereto, permanently blocking a cable line and a ground side so as to prevent characteristic changes of a current limiting device and system breakage, and when it is possible to individually display fault states in order to easily check the system by providing an individual fault display device, visually checking a switch, and preventing possible faults in the system, thus increasing the efficiency of the operation, management and maintenance of the communication system, which includes a melting insulation material deposited on the upper surface of an input terminal of the semiconductor; a ground-side spring contact point disposed on the melting insulation material and connected to the ground; and a fault display lamp-side spring contact point disposed on the melting insulation material and connected to a fault display lamp receiving power.
摘要:
An improved overvoltage automatic prevention apparatus having individual fault displays and permanent ground functions capable of rapidly and safely protecting load parts of the system from overvoltage caused by a thunderbolt or surge and protecting the communication system by providing automatically operable permanent ground and individual fault display functions when a series of overvoltage is applied thereto, so that easier fault checks, system management, and maintenance is possible, which includes a gas tube connected to subscriber lines and both sides of the electrode surfaces having grooves and having a ground electrode connected to the ground; melting insulation materials inserted into the grooves and defining openings formed at recesses; a permanent ground-side spring connection bar inserted into the openings of the melting insulation materials and receiving a ground electrode of the gas tube and having protruded contact points formed on the inner sides of both connection plates; and a fault display lamp-side spring connection bar connected to an individual fault display lamp and having protruded contact points formed on the inner side of both connection plates and inserted into the other openings of the melting insulation material.
摘要:
A method for reducing the cholesterol level in mammalian blood by administering a water soluble cellulose ether thereto. The cellulose ethers have a viscosity, measured as a 2% aqueous solution at 20.degree. C., of at least about 35 cps. Oral administration is preferred, and, in one embodiment the high viscosity water soluble cellulose ether is hydroxypropyl methylcellulose, contained in a nutritious foodstuff.
摘要:
Disclosed is directed to a navigation system using POI code numbers, and an operating system and method thereof. In the system according to the invention, information matching to real states, including POI code numbers, local information, and business information, is stacked on a database to provide a user with geographic information obtained from searching an identical one matching to a POI code number entered by the user. If there has been an update for the geographic information, new POI code numbers are endowed with the updated information and then stored with being associated to the endowed POI code number. The invention also abstracts pre-registered user information using a vehicle navigation system and then updates the geographic information by transferring the POI code number and the undated information thereof to the vehicle navigation system through a communication network in accordance with the abstracted user information. The invention is able to simply search a destination by means of the POI code number.
