摘要： An apparatus for carrying out a fine servo control and a rough servo control with respect to the rotation of a motor for rotating a recording medium in accordance with information recorded on the recording medium. A fine servo signal is generated on the basis of a reproduction clock, filtered by a first filtering device, and used for the fine servo control. A rough servo signal is generated on the basis of a frame synchronizing signal, filtered by a second filtering device, and used for the rough servo control. The first filtering device has a first frequency band, and the second filtering device has a second frequency band. The upper limit of the second frequency band is lower than that of the first frequency band.

摘要： An unbalanced waveform of a tracking error signal is automatically corrected within a short period of time. A peak value and a bottom value of a tracking error signal are obtained by a peak-hold circuit and a bottom-hold circuit, respectively. Based on the peak value and the bottom value, an amount of offset measured from a reference level and an amplitude of the tracking error signal are computed. An adjustment value is computed for correcting the unbalance between the peak value and the bottom value based on the amount of offset and the amplitude of the tracking error signal. The adjustment value is fed back to a tracking balance circuit so that the waveform of the unbalanced waveform of the tracking error signal is corrected.

摘要： A crystal resonator comprises a first vibrating region provided on a crystal wafer, a second vibrating region provided on the crystal wafer, the second vibrating region having a different thickness and positive/negative orientation of the X-axis from those of the first vibrating region, and excitation electrodes which are provided respectively on the first vibrating region and the second vibrating region for causing the vibrating regions to vibrate independently. Frequencies that change by different amounts from each other relative to a temperature change can be retrieved from one vibrating region and the other vibrating region. Thus, based on an oscillating frequency of the vibrating region in which a clear frequency change occurs relative to the temperature, the oscillating frequency of the other vibrating region can be controlled. Thereby, increases in the complexity of the crystal oscillator can be suppressed.

摘要： Even when a module constituting a multi-module becomes an unavailable module, transfer of substrates can be promptly performed, while restricting generation of inferior products. When a destination module of a multi-module becomes unavailable before a substrate is transferred to the destination module, a destination of the substrate is changed to a module to which a substrate subsequent to the substrate is to be loaded. Upon generation of an unavailable module, before the transfer unit accesses the module on an upstream end of the transfer cycle, the transfer cycle proceeds until a precedent substrate becomes ready to be unloaded from the changed destination module. Alternatively, upon generation of an unavailable module, when the transfer unit is located on an upstream side of the unavailable module in the transfer cycle, the transfer operation of the transfer unit is made standby until a precedent substrate becomes ready to be unloaded in the changed destination module.

摘要： A wavelength displacement correcting system and method where a monochromatic beam from an LED is incident through an incident slit of a spectral device and is diffracted on a diffraction grating to form a dispersed light image. Information relating to the dispersed light image is outputted and a wavelength displacement is calculated, using a forward voltage value corresponding to the constant current, and a forward voltage initial value. Wavelength displacement amounts of at least two diffracted beams are calculated, using output values of the at least two diffracted beams, and diffracted beam output initial values with respect to the dispersed light image. A dispersion width is calculated, using the calculated wavelength displacement amount of the beam, and the calculated wavelength displacement amounts of at least two diffracted beams.
