摘要:
There is provided a cable for data transmission which can be wired and constructed without damaging a surface of a wall, ceiling, floor or the like, without using any clamps and which does not degrade appearance of a wired space, and further, allows the wiring construction of the cable provided with a plurality of core wires in a state of less crosstalk. A cable (1) for data transmission includes a core wire (2) having a medium that transmits data and a coating member (4) having adhesiveness and coating at least part of the core wire (2). In this way, because of the adhesiveness of the coating member (4), it is easy to stick the cable onto a wall (6) or the like. Moreover, since a wiring construction of the cable on a surface of the wall (6) or the like without using a clamp, screw or nail is made possible, only the cable is exposed on the surface of the wall (6) or the like and the appearance thereof is improved.

A high-frequency current detector of a plasma processing apparatus detects a high-frequency current produced when high-frequency power in the range that does not cause generation of plasma in a chamber is supplied from a high-frequency power supply source to the chamber. The high-frequency current detector outputs the detected high-frequency current to a computer. The computer compares the high-frequency current received from the high-frequency current detector with a reference high-frequency current. When the received high-frequency current matches the reference high-frequency current, the computer determines that the process performance is normal. Otherwise, the computer determines that the process performance is abnormal. In this way, high-frequency characteristics specific to the apparatus are detected and the process performance are evaluated based on the detected high-frequency characteristics.

A device for measuring focusing characteristics of an optical pickup and/or an optical disc capable of measuring characteristics of focusing states with high accuracy by a simplified circuit. An arithmetic-logic unit 12d controls an offset supplying circuit 23 for applying an offset voltage to a focusing servo control signal. This arithmetic-logic unit 12d detects an error rate of the playback data in such a state in which the focusing position of the laser light is deviated by a pre-set offset amount. The arithmetic-logic unit 12d sequentially varies the offset voltage to repeat the above processing for detecting the error rate. The arithmetic-logic unit 12d approximates the relationship of the error rate to the offset amount by a quadratic curve based on detected data. The offset amount which minimizes the error rate is found from this equation of approximation.

A plasma is supplied from a plasma source to a space between an upper electrode plate and a lower electrode plate disposed opposite to and in parallel with the upper electrode plate when producing a plasma in the space between the electrode plates for plasma processing by applying radio-frequency power to the electrode plates. The plasma source produce a plasma by inductively coupled discharge, radio-frequency discharge or microwave discharge. A plasma processing apparatus is obtained which is capable of producing a parallel-plate plasma by discharge in a space of a relatively low pressure and is capable of processing a large diameter workpiece uniformly at a high processing rate.

A device for supporting and positioning the objective lens in an optical reading apparatus, such as, a video disc player, comprises a first pair of parallel leaf springs attached at one end thereof to a fixed support member for motion parallel to a record medium surface. A movable frame is attached to the other ends of the first springs, and a second pair of leaf springs movable perpendicularly to the record medium surface extend from the frame, the second springs being generally parallel to and between the first pair but with their faces perpendicular to those of the first pair. The objective lens is mounted at the free ends of the second pair of springs, and is movable electromagnetically in orthogonally related directions by means of coils and magnets associated with the objective lens and with the frame.
