摘要： A direct current output voltage is switched by two switching units and a current alternately changing directions is supplied to a primary winding of a transformer. An alternating voltage induced in a secondary winding of the transformer is rectified and smoothed, and is applied to a control circuit. A bidirectional switching unit is connected in parallel with the primary winding, and is controlled by the control circuit so that the primary winding is short-circuited by the bidirectional switching unit and an exciting energy of the transformer is held continuously.

摘要： A laser marking apparatus, capable of marking at a high scanning speed, effectively utilizing a laser power, and providing high marking accuracy, irradiates an incident laser beam from a laser beam source onto a marking surface by raster-scanning through a raster scanning system. The raster scanning system includes an X-direction polarizing mirror, a Y-direction polarizing mirror, a field lens, and a mask. A double polarizing prism, which includes a pair of polarizing prisms (13a, 13b) for branching the incident laser beam (1) into twin laser beams, is arranged in series at an intermediate position between the laser beam source (2) and the upstream one of the X-direction polarizing mirror (3) and the Y-direction polarizing mirror (8). An adjusting means is provided to vary the distance between the two polarizing prisms (13a, 13b) or to rotate one or both of the polarizing prisms (13a, 13b) to vary the rotation angle by rotating one of the twin laser beams around the other, to thereby vary the distance between the centers of the twin laser beams as they irradiate the mask.

摘要： A switching power supply supplies a regulated output voltage and suppresses spike voltage and spike current generated by a switching action of transformers, and suppresses switching frequency drift due to load variation. Output stability of multi-output design is improved and recovery of rectifying diodes by a current resonance are suppressed. A reduction of noise interference to electronic equipments and power loss in the switching power supply itself results. A series connection of a primary winding of a first transformer and a first switching means, which repeats an on/off action is connected across a d-c power source. A series connection of a second switching means, which repeats an on/off action alternately with the first switching means, and a first capacitor is connected in parallel with the primary winding of the first transformer. A series connection of a primary winding of the second transformer and a second capacitor is connected in parallel with the second switching means. Regulated d-c outputs are taken out from each secondary winding of the transformers through rectifiers/filters. A control circuit supplies on/off signals, which on/off-ratios are varied according to one of the regulated d-c outputs, to the first and the second switching means.

摘要： Disclosed are an audio encoding device and an audio decoding device which reduce degradation of subjective quality of a decoding signal caused by power mismatch of a decoding signal which is generated by a concealing process upon disappearance of a frame. When a frame is lost, a past encoding parameter is used to obtain a concealed LPC of the current frame and a concealed sound source parameter. A normal CELP decoding is performed from the obtained concealed sound source parameter. Correction is performed by using a conceal parameter on the obtained concealed LPC and the concealed sound source signal. The power of the corrected concealed sound source signal is adjusted to match a reference sound source power. A filter gain of the synthesis filter is adjusted so as to adjust the power of a decoded sound signal to the power of a decoded sound signal during an error-free state. Moreover, a synthesis filter gain adjusting coefficient is calculated by using an estimated normalized residual power so that a filter gain of a synthesis filter formed by using a concealed LPC is a filter gain during an error-free state.

摘要： An audio decoding device capable of suppressing an information amount for a lost flame compensation process and encoding efficiency is provided. A decoded sound source generator generates a lost frame's CELP decoded sound source signal. A pitch pulse information decoder CELP decodes a pitch pulse position information and a pitch pulse amplitude information. A pitch pulse waveform learner learns a pitch pulse learning waveform in a past frame in advance from the lost frame. A convolution adjuster amplitude-adjusts the pitch pulse learning waveform according to the pitch pulse amplitude information by considering a predetermined number of waveforms peripheral to a peak position of the lost frame's CELP decoded excitation signal, and convolutes a pitch pulse waveform into a time axis which has been amplitude-adjusted according to the pitch pulse position information. A sound source signal corrector adds or replaces the pitch pulse waveform convoluted into the time axis to the lost flame decoded sound source signal.
