  • Publication number: 20200164562
    Abstract: A rubber sheet monitoring apparatus (1) comprises a first imaging unit (11), a second imaging unit (2), a first generation unit (142) and a second calculation unit (146). The first imaging unit successively acquires images of a first optical cutting edge (CL1) formed on a front surface of a rubber sheet (6). The second imaging unit successively acquires images of a second optical cutting edge (CL2) formed on a back surface of the rubber sheet. The first generation unit performs, for each of the successively acquired images of the first optical cutting edge, generation of first data (D1) representing height variation of a widthwise cross-sectional edge of the rubber sheet using the image of the first optical cutting edge, and performs, for each of the successively obtained images of the second optical cutting edge, generation of second data (D2) representing height variation of a widthwise cross-sectional edge of the rubber sheet using the image of the second optical cutting edge.

  • Patent number: 7498076
    Abstract: A method for manufacturing a porous dielectric substrate including patterned electrodes includes a patterned electrode-forming step of preparing a support plate having a releasable flat face and then forming the patterned electrodes on the flat face, a porous dielectric substrate-forming step of feeding a material for forming the porous dielectric substrate onto the flat face having the patterned electrodes arranged thereon to form the porous dielectric substrate in which the patterned electrodes are embedded, and a separation step of separating the support plate from the porous dielectric substrate having the patterned electrodes embedded therein. In the patterned electrode-forming step, the patterned electrodes formed on the flat face are processed to have rough surfaces in the patterned electrode-forming step. Alternatively, after the flat face is coated with a releasing agent, the patterned electrodes are formed on the resulting flat face.

  • Patent number: 7492194
    Abstract: An oscillator includes phase frequency detectors, each detecting the phase difference between two input signals (output signal and external reference signal) and outputting a control command signal for controlling the output signal to achieve a desired frequency on the basis of the phase difference. A plurality of ICs, each including a phase frequency detector, frequency dividers, a charge pump, and a lock detection circuit, is operated in parallel. A composite control command signal generated by combining outputs of the phase frequency detectors is output via a loop filter to a voltage-controlled oscillator. Whether phase noise is reduced sufficiently is determined on the basis of detection results by an amplitude detection circuit for detecting the amplitude of an AC component of the composite control command signal and the lock detection circuits. The phase frequency detectors are repeatedly reactivated until the phase noise is reduced sufficiently.
