  • Patent number: 5293192
    Abstract: A camera of the present invention comprises a stationary frame adjustable in position with respect to a camera body in the direction of an optical axis; a cam frame disposed around an outer circumference of the stationary frame to be rotatable about the optical axis and movable in a direction of the optical axis with respect to the stationary frame; a finder optical system provided on the camera body; and a finder optical system driving cam provided integrally with the cam frame for driving the finder optical system. In-focus position adjustment of a photographing optical system of the camera is performed during assembly by moving only the stationary frame in the direction of the optical axis, while the cam frame is kept immobile with respect to the camera body.

  • Patent number: 5287137
    Abstract: An encoder device of the present invention comprises:a motor for driving a photographing lens,a pulse generator operated by a drive force transmitted from the motor to the photographing lens, and generating a coarse pulse signal and a fine pulse signal corresponding to rotation of the motor,counters for counting the coarse pulse signal and the fine pulse signal, respectively,a reset device for resetting the number of the coarse pulse signals counted by the counters when the photographing lens reaches a predetermined position,a motor drive/controller for controlling start and stop of drive of the motor, anda detector for determing a value related to the driven position of the photographing lens upon halting of the driving of the motor based on the number of the coarse pulse signals counted from the predetermined position for resetting and the number of the fine pulse signals counted after a final one of the coarse pulse signals has been output.

  • Patent number: 4984000
    Abstract: A lens driving apparatus for use in a camera, which adjusts the focus or the angle of view of a lens by means of a motor driven in accordance with the amount of rotation and the rotational angle of rotational operation member provided on a lens body or a camera body, comprises a first detector for detecting the operational direction and the amount of operation of the rotational operation member and generates an operational direction signal and an amount-of-operation pulse signal, a second detector for detecting the actual amount of driving of the lens and generating a drive pulse signal, a motor driver for rotating the motor in a direction according to the operational direction signal until the difference between the count value of an amount-of-operation pulse and an amount-of-driving pulse becomes 0, and a CPU for detecting pressing of the lens against a drivable end portion, inhibiting driving of the lens in that direction, and changing the resistive force of the operation member when operated, thus alarmin

  • Patent number: 4970352
    Abstract: A multicore coaxial cable includes a conductor layer, an insulator layer surrounding the conductor layer, plastic tape surrounding the insulator and a metal shield surrounding the plastic tape. The exterior surface of the plastic tape is coated with a metal layer to contact the metal shield to reduce the electrostatic noises in the cable.

  • Patent number: 4967341
    Abstract: A set of sorted columns of one table stored in a DB machine are binary-searched by a hardware in synchronism with data transfer when another table is read from a disk unit, to select a row to be joined. Where a key word sequence to be searched is stored in ascending or descending order, determination of a maximum address in an area in which key words smaller than a search key are stored and determination of a maximum address in an area in which the key words smaller than or equal to the search key are stored are parallelly executed to determine the store range in one searching.

  • Patent number: 4716455
    Abstract: In a solid-state imaging device, a chrominance signal different from a signal to be obtained at a specified time among a plurality of chrominance signals to be successively obtained from a solid-state image sensor is interpolated with the chrominance signal obtained directly before the time of interpolation, or with the chrominance signal of a picture element corresponding to the signal to be obtained at the time of interpolation based upon the subject being achromatic. The particular signal to be used for the interpolation is decided based upon the difference between the signal to be obtained at the time of interpolation and a signal of the same chrominance obtained one cycle before the time of interpolation, or the differences between signals obtained directly before the time of interpolation and to be obtained directly after the time of interpolation and the chrominance signals obtained one cycle before the times of these signals.
