An information reproducing apparatus is provided with: a clamping device (900) capable of clamping and clamp-releasing a recording medium (100); a rotating device (20) for rotating the recording medium clamped by the clamping device; a reading device (30) disposed opposite to an information record surface of the recording medium for reading information recorded on the information record surface of the recording medium; a driving device (34, 34D, 32) capable of moving the reading device in a radial direction of the recording medium; and a linkage device (24, 83, 85) for linking a clamping or clamp-releasing action by the clamping device with a movement of the reading device by the driving device. The driving device moves the reading device as a first driving voltage is supplied to the driving device upon reading the information recorded on the information record surface, the first driving voltage including such a value that the action of the clamping device is not linked with the movement of the reading device by the linkage device.

An n-type cladding layer formed of a non-single crystal body of n-type AlGaN, a light emitting layer containing a plurality of micro-crystals made from ZnO, and a p-type cladding layer formed of a non-single crystal body of p-type BN are sequentially stacked on a substrate made from quartz glass. An insulating layer is formed between the n-type cladding layer and the p-type cladding layer in such a manner as to bury spaces between the micro-crystals, to thereby prevent occurrence of leakage current. The insulating layer is formed by oxidizing the surface of the n-type cladding layer. Since the light emitting layer contains the plurality of micro-crystals improved in crystallinity, it is possible to enhance the emission efficiency, to extend the selection range of each of materials for forming the light emitting layer, n-type cladding layer, p-type cladding layer, and substrate, and to form a device array on a common substrate having a large area.

摘要:
A method of producing a heat exchanger in which a fin block of porous metal and fin plates connected to the fin block are unitarily secured to a serpentine heat-transmitting pipe. A plurality of fin molds produced with the use of plastic patterns formed therein with continuous, three-dimensional cavities are assembled with the heat-transmitting pipe shaped beforehand into a serpentine form in such a manner that the fin molds enclose the heat-transmitting pipe with suitable spacing intervals defined between the fin molds themselves and between the fin molds and the heat-transmitting pipe. Molten metal of high thermal conductivity is cast into continuous cavities in the fin molds and into the spacing intervals, and the material of the fin molds is removed after the molten metal has solidified.

A liquid crystal display device restraining display defects even in a structure having a potential difference between an externally-connected electrode potential and the mean potential of the drive waveform of a liquid crystal material. An electrostatic charge stored in the vicinity of a liquid crystal layer of the liquid crystal display device as a result of the potential difference between an externally-connected electrode potential and the mean potential of the drive waveform of the liquid crystal material is dispersed by employing a capacitor or an arrester connected to ground. Accordingly, discharge of the stored charge is facilitated, and occurrence of display defects is restrained.
