Abstract: PURPOSE: A mail box interface system is provided to make it possible interfacing a data communication between a PLC(Power Line Communication) system and an upper level computer without changing a closed type PLC system so that it can offer an open type structure interoperable with a general purpose system. CONSTITUTION: The system comprises an I/O module(100), the first and the second signal converter(200, 700), a receiving controller(300), the first and the second memory(400, 500), a transmission controller(600), a clock controller(800), an address selector(900), and a bus interface(1000). The I/O module(100) offers an I/O connection for connecting to a PLC control system. The first and the second signal converter(200, 700) convert the signal, input or output via the I/O module(100), into an analog signal or a digital signal, respectively. The receiving controller(300) converts the data, transmitted by the first signal converter(200), into a certain type signal, and uploads the converted signal at a selective address of the first memory(400). The first and the second memory(400, 500) share received/transmitted data with a memory of a PC by setting their address corresponding to receiving/transmitting addresses of the memory of the PC. The transmission controller(600) reads data from the second memory(500), and outputs the read data to the second signal converter(700). The clock controller(800) generates a reference clock for operating the controllers(300, 600). The address selector(900) selects memory addresses at the first and the second memory(400, 500) for storing or reading the transmission/receiving data. The bus interface(1000) interfaces the first and the second memory(400, 500) with a transmission/receiving data storage of the memory of the PC.

Abstract: PURPOSE: A manufacturing method of artificial leather products which are characterized by having cubic patterns like natural leather and having various patterns is provided. CONSTITUTION: Artificial leather products are comprised of: a base layer(10) manufactured with leather or fabric; a first patterns(10a) having irregular unevenness; a second patterns(10b) formed by grinding sectionally the first patterns(10a); and a resin layer(20) containing a pigment and showing fixed color tone. The artificial leather products are obtained by the steps of: forming an original form having unevenness with a cast; heating a mold at proper temperature, followed by compressing one surface of the mold with the unevenness of the original form to form a pattern form; drying the mold; putting liquid resin material, stone powder and a hardening accelerator into the pattern form of the mold to form the first patterns(10a); hardening the first patterns(10a), followed by coating a surface with an adhesive; heating the coated surface; coating the surface of the first patterns(10a) with the adhesive, bonding the base layer(10) and compressing the bonded layer with a heat press; separating the patterns bonded on the base layer(10) from the mold; and then grinding the first patterns(10a) sectionally to form the second patterns(10b).
