IPC: H03J5/24
Filed: 2003-08-08
Abstract: <P>PROBLEM TO BE SOLVED: To provide a direct conversion tuner capable of receiving both UHF band digital television signal and VHF band digital television signal using a single oscillator.  <P>SOLUTION: The direct conversion tuner comprises mixers 5, 6 and 13, 14 which orthogonally transform the digital television signal arrayed in the high channel of VHF band and the television signal arrayed in channels 13 and 35 of UHF band directly to base band signal, and an oscillator 22 which supplies local oscillation signal to the mixers 5, 6, 13, and 14. The oscillator 22 is oscillated at sixfold of the frequency of high channel in VHF band or at double of frequency of channels 13 and 35 in UHF band, and then the oscillation signal which is double the frequency is divided by two while the oscillation signal of sixfold the frequency is divided by six, to generate local oscillation signals in which phases are orthogonal to each other. The divided local oscillation signal is supplied to the mixers 5, 6 and 13, 14.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Filed: 2003-08-13
Abstract: <P>PROBLEM TO BE SOLVED: To provide an optical pickup capable of easily correcting astigmatism for a plurality of light sources, and an optical disk playback device.  <P>SOLUTION: A second laser light source is arranged nearer an optical axis than a first laser light source, a second laser beam from the second laser light source is converged on an optical disk by a numerical aperture smaller than that of a first laser beam from the first laser light source, and further astigmatism caused by the shifting of the first laser beams from the optical axis is corrected by an astigmatism correcting means. The astigmatism of the second laser light source is smaller because it is nearer to the optical axis. There is a possibility of an increase in astigmatism because of the passage of the second laser beam through the astigmatism correcting means. However, this astigmatism is not such a big problem because the numerical aperture is smaller than that of the first laser beam.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To prevent disturbance of sound field when audio reproduction is performed by a class D amplifier of multichannel system, and to reduce noise due to switching.  <P>SOLUTION: The sampling rate converter 2a at each voice output section of front left channel, front right channel, surround left channel and surround right channel is asynchronous type. ΔΣ modulation/PWM sections 3a-3d provided at the poststage output PWM signals to respective switching/amplifying sections 4a-4d by performing modulation with sync signals shifted by delay circuits 8a-8c to have a different timing from each other. Since phase shift (mismatch of reproduction time axis) does not occur among digital audio signals being processed at the ΔΣ modulation/PWM sections 3a-3d and the timing of carrier period T of the PWM signals being inputted to the switching/amplifying sections 4a-4d is shifted, switching timing of the switching/amplifying sections 4a-4d is shifted and noise is reduced.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To fabricate a nonvolatile random access memory (NVRAM) with a device that does not use any dopant at all.  <P>SOLUTION: A heteroepitaxial junction interface between different oxide insulators is used for the NVRAM device. The electrical resistance value for the electric current flowing in the junction interface parallel to the interface is changed in a nonvolatile manner by an electric current or voltage pulse applied to the junction interface via the same path as that of the electric current. A two terminal NVRAM device that can write, read and erase information repetitively is provided by utilizing the nonvolatile change of the electrical resistance of the interface by the pulse. The junction between the two different oxide insulators is, for example, a junction between perovskite-type oxides expressed respectively by chemical formulas ABO<SB>3</SB>and CDO<SB>3</SB>, where A and C are alkali metals (group 1A of the periodic table), alkaline-earth metals (group 2A of the periodic table), or rare-earth elements; B is a transition metal (groups 2B to 7B, and group 8 of the periodic table) or an element of groups 3A to 5A of the periodic table. O is oxygen. The elements of A and B may be mutually exchanged. Also, both A and B may be transition metals.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
