Granted: 1999-06-01
Abstract: A force and pressure sensor is provided having two sets of parallel electrodes which are positioned facing one another and arranged so that electrodes of one set cross the electrodes of the second set at an angle to create a plurality of electrode intersections. Pressure-sensitive resistive material lies between the electrodes at each intersection. An adhesive layer is applied to at least one of the electrode sets in areas between electrode intersections to secure the first and second electrode sets in facing relationship, the adhesive layer preferably being applied in a pattern which provides passages where the adhesive layer does not exist to allow air to escape from interior areas of the electrode set. The thickness of the adhesive layer may be adjusted to permit preloading or to provide a threshold level for the sensor. In order to permit electrodes of the electrode set to be trimmed around their periphery, electrical contact to each electrode of the electrode sets is made intermediate the ends of the electrodes. This is accomplished by providing an insulating layer over the rear of each electrode set having holes therein at the desired intersection points and having a plurality of connecting conductors on the back of the insulating sheet, one for each electrode, which make contact with the corresponding electrode through the hole in the insulating sheet.

Abstract: PURPOSE: A low capacity switching system for an ISDN(Integrated Services Digital Network) is provided to extend a subscriber capacity, and to supply various ISDN services. CONSTITUTION: An S connector(10) temporally stores a message when each subscriber terminal attempts connection, and stores the message in a RAM(Random Access Memory) again, then performs interfaces of many ISDN(Integrated Services Digital Network) subscriber terminals. An R connector(20) reads a message received through an SLIC(Subscriber Line Interface Circuit) from an analog subscriber, and converts the message into an ISDN message to transmit the converted ISDN message to a main controller(30), then performs interfaces of analog subscriber terminals. The main controller(30) performs a most significant control in order to supply synchronous clocks to each function. A U connector(40) extracts an only D channel message from a received signal to temporally store the extracted message, and notifies an interrupt of a message reception. Then, the U connector(40) reads the message to add necessary information, and transmits the message to the main controller(30), finally supplies many central office interfaces. PRI(Primary Rate Interface) connector(50) equips a D channel control function for controlling a D channel, and supplies an interface with the main controller(30) by using a mounted SDLC(Synchronous Data Link Control) function.

Title: Biodegradable polyethylene composition coupled chemically by starch and process thereof
Inventor: YU YOUNG-DEUK

Abstract: The biodegradable polyethylene composition bonded chemically with starch comprises 100 wt. parts matrix resin, 5-400 wt. parts biodegradable incorporating material, 0.01-10 wt. parts coupling agent, 0.01-1.0 wt. parts radical initiator, 0.01-5 wt. parts Lewis acid catalyst, 0.01-10 wt. parts autoxidizing agent and 0.01-10 wt. parts plasticizer. the physical properties are minimized by reacting matrix resin with starch chemically using a coupling agent in the presence of an organic acid catalyst. At the same time, the production cost saving is achieved by simplifying the process. In the prior technology, the problems associated with low physical properties caused by starch incorporation were approached only in terms of enhancing physical interacting strength between matrix resin and starch.
