    摘要: Arranged in the bottom of a cup-shaped cylindrical casing is a solid disc form of axially uniformly magnetized permanent magnet having a single pair of poles each formed on one or the other of its opposite end faces over the whole region thereof. A circular plate of magnetically permeable material is fixedly mounted on the magnet and to which plate a set of coiled posts are fixedly fitted. The casing is preferably formed on its outer periphery with cooling fins for dissipation of heat generated therein during printing operation. The magnet and the plate thereon, identical in outer diameter, are radially spaced an appropriate slight distance from the inner wall surface of the casing to form a bypass circuit for the flux of the magnet. Arranged in the open top of the casing is a spring-charge type print hammer assembly which includes a radial array of resilient tongues (hammers) and print wires secured thereto preferably through the medium of flat armature plates fixed to the respective tongues. The print head is particularly suited for high-speed printing operation with low power requirements and, owing primarily to the extremely simplified form of magnet used, is of reduced fabrication cost. The armature plates, in cooperation with a yoke plate slotted to receive the plates serve to compensate for any possible increase in reluctance of the main magnetic circuit and increase the kinetic energy of the tongues or print hammers when released.

    摘要: An objective lens driving apparatus includes an objective lens (13) collecting a light flux emitted from a light source on a optical disk (11), and a lens holder (14) holding the objective lens (13). The lens holder (14) includes a first bonding portion (14i) and a second bonding portion (14j) for holding the objective lens (13) by means of bonding. The objective lens (13) is fixed to the lens holder (14) by applying a first bonding adhesive (25) to the first bonding portion (14i) to thereby bond the objective lens (13) thereto, adjusting an inclination of an optical axis of the objective lens (13) while causing the first bonding adhesive (25) to deform, and applying a second bonding adhesive (26) to the second bonding portion (14j). The second bonding adhesive (26) has a larger Young's modulus after curing than the first bonding adhesive (25).

    摘要: The object of the present invention is to use the same FIFO line memory for both enlargement and reduction during variable-magnification processing in the scan direction, allowing reduction in circuit board area, reduction in power consumption, and reduction in cost, and to provide an image processing apparatus that allows variable-magnification processing to be carried out such that the speed of a scanning unit that captures image data during variable-magnification processing in the cross-scan direction is constant. During processing to enlarge an image in the scan direction, image data travels from CCD circuit board, passing through gate b of selector, is written to and read from FIFO memory, and from gate b of selector is written to memory provided at variable magnification unit. At variable magnification unit, image data is read from memory a plurality of times in correspondence to enlargement ratio, changing the magnification of the image data. Furthermore, image data is output through gate a of selector to LSU unit. During processing to reduce an image, image data travels from CCD circuit board, passing through gate a of selector, is input to variable magnification unit where it is subjected to variable-magnification processing, passes through gate a of selector, is written to and read from FIFO memory, passes through gate b of selector, and is output to LSU unit.

    摘要: An optical wavelength tunable filter includes an optical waveguide having a first branched optical waveguide and a second branched optical waveguide merging into one piece of the optical waveguide through which optical wavelength multiplexed signals, each having a different wavelength component being incident from an end face of the first branched optical waveguide, are propagated. A comb-type electrode (or a plurality of comb-type electrodes each corresponding to each of the different wavelength-components) is mounted vertically to apropagating direction of the optical wavelength multiplexed signals leaving a specified space apart from the optical waveguide formed by a merger of the branched first branched optical waveguide with the second branched optical waveguide. A voltage applying device applies a predetermined voltage to each of the comb-type electrodes.
