20090081977 | BROADCAST RECEIVING APPARATUS - When a RF signal is output, noise is prevented from appearing in the RF signal without degrading convenience. | 03-26-2009 |
20090083821 | Broadcast receiving apparatus - An appropriate direction and gain value of a smart antenna are efficiently searched for. The MPU | 03-26-2009 |
20090208025 | ACTIVE NOISE REDUCTION SYSTEM - An electromechanical converter has independent electric input sections. The output of an active noise reduction controller is inputted into an electric input section and the audio signal from an audio section is inputted into an electric input section. These are mechanically combined at a vibration section and the combined signal is radiated as a sound wave into the space. With such a structure, both the active noise reduction function and the audio reproduction function are realized without installing a large device in an existing audio reproduction apparatus. | 08-20-2009 |
20090289705 | PULSE MODULATION TYPE ELECTRIC POWER AMPLIFIER - A pulse modulation type electric power amplifier includes a pulse modulator that receives as input a clock and an input signal, and converts the input signal to a pulse train, an output control circuit that receives as input the pulse train output by the pulse modulator, and controls output of the pulse train, an output circuit that performs switching according to the pulse train output by the output control circuit, a comparator that converts an output terminal voltage of the output circuit to a high or a low digital value, and a short-circuit determination circuit that determines whether an output short circuit has occurred based on a state of an output signal of the comparator, and outputs an output prohibition signal to the output control circuit when an output short circuit is detected. The output control circuit controls output of the pulse train when the output prohibition signal is input, so that the output circuit stops the switching operation. An output short-circuit protection circuit can thereby be configured simply with little circuitry, and is thus small, low power, and integrated easily. | 11-26-2009 |

20120113784 | OPTICAL PICKUP - An optical pickup having a first diffractive optical element that acts on light of a specific wavelength, the first diffractive optical element being arranged in an optical path for guiding reflected light from an optical disk to a photodetector. The photodetector comprises a first detector including a first main light receiver divided into a two-by-two square matrix, and a second detector including a second main light receiver divided into a two-by-two square matrix, the second detector being arranged in a row with the first detector. When the light of a specific wavelength is used, zero-order light of the first diffractive optical element is received by the first main light receiver, +first-order light (or −first-order light) diffracted by the first diffractive optical element is received by the second main light receiver, and a tracking error signal is generated using an output signal from the second main light receiver. | 05-10-2012 |
20120281518 | OPTICAL PICKUP - An optical pickup has an objective lens that is shared for light of three wavelengths. The effective diameter of the light that passes through the objective lens decreases in a sequence of the light of a first wavelength (light for a first optical disk), the light of a second wavelength (light for a second optical disk) and the light of a third wavelength (light for a third optical disk); and the light of the third wavelength is incident on the objective lens in a finite system. The objective lens is provided so that the focal distance of the light of the second wavelength is greater than the focal distance of the light of the first wavelength. | 11-08-2012 |
