The present invention provides a communication semiconductor integrated circuit wherein a first control voltage for a voltage-controlled oscillator circuit is controlled based on a feedback signal sent from a PLL loop to generate a carrier frequency signal used as a carrier, and under the generation of the carrier frequency signal, a second control voltage for the voltage-controlled oscillator circuit is controlled based on the output of a DA converter circuit for DA-converting a code generated based on transmit data to thereby frequency-modulate an oscillation signal. The communication semiconductor integrated circuit is provided with a frequency adjustment/control circuit which measures the frequency of an oscillation output of the voltage-controlled oscillator circuit and adjusts a reference current value of the DA converter circuit according to the difference between the measured value and a target value to thereby correct the frequency.

The erase voltage applied to a set of non-volatile storage elements being erased is structured to provide controlled shifts in the threshold voltage of the storage elements. The erase voltage is applied as a series of voltage pulses, when necessary, to shift the threshold voltage of to-be-erased memory cells below a verify level indicative of an erased condition. To avoid over-erasing the memory cells, the second erase voltage pulse is decreased, or not increased, in magnitude when compared to the previously applied voltage pulse. By decreasing or not increasing the size of the erase voltage, the amount of charge transferred from the cells by the second pulse is controlled to more accurately position an erased threshold voltage distribution for the cells near the verify level. Subsequent erase voltage pulses are increased in magnitude to provide further erasing when needed.

In order to make it possible to improve throughput of AFM scratch processing, enable correction of small defects in clear defect correction with a high degree of precision, and enable correction in a shorter period of time in the event of overcutting by AFM scratch processing, throughput of AFM scratch processing is increased by maximizing high-resolution of the electron beam device and minimizing the time taken in observations using a device incorporating both an electro-optical system and an AFM head in a vacuum, correcting small clear defects with high precision by eliminating portions left over from AFM scratch processing after applying a clear defect correction film using an electron beam while providing light-blocking film raw material, and correction in a short time is made possible by eliminating portions remaining using AFM scratch processing after applying a clear defect correction film using an electron beam while providing light-blocking film raw material also in cases of overcutting in AFM scratch processing.

The present invention provides a method for correcting a shift of an output wavelength of a light source. The output wavelength shift correcting method derives simple equations through experimental processes, predicts a shift degree of the output wavelength with respect to a varied input current using the equations whenever a drive current is reset later, and adjusts a drive temperature according to the predicted shift degree, thus correcting the shift of the output wavelength. The output wavelength shift correcting method is advantageous in that it provides a method of locking an output wavelength of each light source without continuously operating a wavelength locker or a wavelength measuring device, thus reducing the operating cost of the optical communication system.

The invention displays a lattice fringe on a spatial light modulator such as a liquid crystal panel or a digital mirror device panel, irradiates it with laser beams in three primary colors red, green and blue, and uses a primary diffracted beam created by the lattice fringe as an image recording reference beam. On moving the lattice fringe on the spatial light modulator on the modulator, a phase of the diffracted beam shifts due to a movement of a fringe, a phase shift amount of the beam is proportionate to an amount of movement of the fringe, and becomes unconnected to a wavelength of the beam. By this method, as an optical phase can be accurately shifted rendering unnecessary a device for detecting or regulating the optical phase, a system configuration of an image recording apparatus becomes simple.

In an information reproducing apparatus in which a liquid crystal lens element is used for the selection and switching of layers, the instability of servo control during the switching of the layers due to the overlapping of signals from two layers is eliminated and the focal point is shifted onto the correct switched layer. During the switching of the liquid crystal lens, a focus bias is added depending on the direction in which the layers are switched so as to stabilize servo control.

The invention relates to a frequency-domain migration-based de-chirping inverse synthetic aperture radar (ISAR) envelope alignment method. According to the method, based on the alignment of a conventional envelope correlation method, the accuracy of envelope alignment is improved by using the frequency-domain migration property of Fourier transform; and the maximum constraint condition of the accuracy of traditional envelope alignment is that the error of migration alignment cannot break through the limitation of half of a range resolution cell when migration alignment is carried out under a condition that time-domain signal sampling is completed, and the solidification of range units is completed, wherein one range unit is one complex data representation. Since FFT operation is required to be carried out before the formation of range units in de-chirping signal processing, echo signals are multiplied by a frequency shift factor before the FFT operation, and accurate migration of data which have been subjected to FFT can be realized.
