Abstract: An optical transmission system accomplishes optical transmission to a long distance by combining a multiplexing line terminal with optical amplifiers, linear repeaters, and regenerators with optical amplifiers combined together. The system also accomplishes the optical transmission to a short distance by directly connecting the linear terminals therebetween, with an electric-to-optic converter replaced by an electric-to-optic converter having a semiconductor amplifier, with an optic-to-electric converter by an optic-to-electric converter having an avalanche photodiode as light receiver, an with no use of any optical booster amplifier and optical preamplifier in the multiplexing line terminal. With these, the optical transmission system can be easily constructed depending on the transmission distance required.

Abstract: A compressed sheet comprises: base fibers constituted by inorganic fibers other than asbestos, or organic fibers, or a combination of both; a rubber; rubber chemicals; and fillers. In the compressed sheet a material with both smoothing and reinforcing effects is exposed at least to one of the surfaces of the compressed sheet. A method of manufacturing a compressed sheet comprises the steps of processing a composition for forming the compressed sheet by feeding it into a pair of rolls comprising a hot roll and a cold roll, thereby laminating the composition into a sheet-shaped material on the hot roll, and then peeling off the sheet-shaped laminated material. In this method the composition is fed into the rolls such that a material with both smoothing and reinforcing effects is exposed at least to that surface of the sheet-shaped laminated material which faces the cold roll.

Abstract: A thermal displacement compensating apparatus capable of compensating for the thermal displacement of the main spindle of a machine tool is disclosed. A feed back scale and a measuring head are provided in order to detect the actual position of the front end portion of the spindle head. Furthermore, a distance sensor is provided for detecting the thermal extension of the main spindle with respect to the spindle head. The output signal from the distance sensor is used for modifying the present position detected by the measuring head or modifying a commanded target position. With this arrangement, a tool attached to the front end portion of the main spindle is moved to the commanded position regardless of the thermal displacement of the spindle head and the main spindle. Another type of compensation apparatus is also disclosed, wherein the measuring head is mounted on a mounting rod, and the mounting rod is automatically moved so as to maintain the distance between the measuring head and the front end surface of the main spindle at a constant distance. With this arrangement, actual position of the front end surface of the main spindle can directly be detected regardless of the thermal displacement of the spindle head and the main spindle.
