A magnetic disk device of the present invention is configured so that a stopper for controlling the movement of a carriage arm is adapted to give rise to play in controlling the carriage arm when the stopper is in the closed state. When a disk rotating means is actuated, the magnetic disk device permits a disk and a magnetic head in the state of fast mutual adhesion to be separated from each other by causing the carriage arm to swing with the stopper kept in the closed state, and consequently, the magnetic disk device enables the disk to rotate without fail.

There is disclosed a data circuit-terminating equipment (DCE) which connects an asynchronous data terminal equipment (DTE) with a PCM trnsmission line having various speeds. Further the DCE can satisfy recomendations of the V25 bis of CCITT. The DCE includes a PLL obtaining a clock from the line, a timing generator generating timings for circuits, a mapping circuit mapping to make data from the DTE match into the line speed, a sending register converting transmission speed of the mapping circuit output to send to the line at the instructed period, a receiving register receiving data from the line to deliver data with the required speed during the required period for the DTE, and a demapping circuit receiving the receiving register output to demap and send to the DTE. In the DCE satisfying the recommendations, the demapping circuit ANDs a clear-to-send signal and bits indicating the synchronized state to send the clear-to-send signal, and a short line shorting the clear-to-send signal and a carrier detect signal is employed.

摘要:
A click tone removing system for a time division switching system which performs switching of speech channels by a highway switch inserted in a highway. When a hook information detector and a dial information detector detect hook information and a dial information, respectively, delivery of a PCM speech sending signal to the highway is prevented by a blocking function for a fixed period of time, so that the highway is controlled to switch the speech channel, thereby removing a click tone generated by dialing. A subscriber's circuit of an exchange, which changes over a speech sending highway and a speech receiving highway by means of a highway switch, is characterized by the provision of an A/D converter for digitizing a speech sending signal to a digitized speech sending signal sent out to the speech sending highway, a D/A converter for converting a digitized speech receiving signal applied from the speech receiving highway into an analog signal, a gate for gating the input signal to the D/A converter, and a control circuit for controlling the gate, so that during real time processing the speech receiving signal highway is interrupted by opening and closing the gate without controling the higway switch.
摘要:
The present invention relates to a resin composition for protective films which comprises an epoxy resin having two or more epoxy groups, a curing agent, a curing accelerator, a solvent, and a colloidal slurry of fine silica particles having an average particle diameter, as determined by conversion from the specific surface area, of 50 nm or smaller, a pH of 6 to 8, and an alkali metal content of 5 ppm or lower. The resin composition gives a protective film which satisfies adhesiveness and visible-light transmission, which are performances conventionally required. The protective film further has high surface smoothness even when the substrate surface is not smoothed. The resin composition has satisfactory storage stability and does not stain liquid crystal. Furthermore, a cured film obtained from the resin composition has excellent high-temperature resistance, especially ITO resistance. The resin composition is hence suitable for use in forming a protective film for the colored resin films of color filters for liquid-crystal display.
