摘要： An optical disc device is provided to allow an optical disc to be attached to and detached from the device, thereby decreasing the size thereof. An optical device comprises an optical pickup(2); a focusing coil(4), a tracking coil(10), and a pair of permanent magnets. The optical pickup is positioned at a front end of a fluctuating arm-type actuator(3). The focusing coil is formed between a fluctuating center of the fluctuating arm-type actuator and the optical pickup. The tracking coil is positioned with a center point in a direction of 90 degrees approximately about the fluctuating center of the fluctuating arm-type actuator with respect to a line(13) connecting the fluctuating center of the fluctuating arm-type actuator and a lens center of the optical pickup. The pair of permanent magnets is horizontally arranged opposite to the tracking coil. A center portion of the tracking coil is positioned at a side opposed to an optical disc rotating center of an optical disc rotating device with respect to the line connecting the fluctuating center of the fluctuating arm-type actuator and the lens center of the optical pickup. The polarities of coil facing surfaces of the permanent magnets are opposed to each other. The tracking coil is positioned over the permanent magnets across the boundary of the permanent magnets.

摘要： The system is selectively operable as a Dolby B-type or Ctype. An input signal is applied in either case to the variable impedance of a high-level side chain through an identical shared filter circuit network. The high-level side chain has two voltage -to-current converters for controlling the variable impedance. By inhibiting the operation of one of two converters, the system operates as the C- type, otherwise the system operates, as the Btype. In the latter case, a current of about half of the minute control current flowing when the system is operating as C-type with no input is passed to the outputs of the two voltage-tocurrent converters.

摘要： Unauthorised use prevention information is registered in a terminal device used for transaction. A terminal control equipment (TCE) is inserted between the portable terminal device and the central unit in order to manage the transactions by the portable terminal devices of respective branch offices. The portable terminal device is a job data input/output device and transmits data entered by an input unit to the TCE 200 and a outputs data received from the TCE (200) to an output unit.

摘要： The elevator group control system comprises several elevator cars arranged for movement across a number of floors of a building. A hall call register is disposed at each of the floors to originate a hall call for calling one of the cars towards the floor. A car call register is in each car for instructing target floors. An allocation evaluation factor computer indicates the suitability of allocation of a newly originated hall call to each car. The computer includes an arrangement for weighting the output signal from floor stop probability evaluation factor relative to the output signal from servicability evaluation factor.
