Abstract: A manufacturing cost of an integrated circuit chip used in a program update system or in an electronic device with program update function is reduced. A first integrated circuit chip has a USB interface circuit, a compression decoder, a CPU and a mask ROM. The first integrated circuit chip is a single chip consolidating a microcomputer with a USB host function and the compression decoder. A second integrated circuit chip has a CPU and an FROM, and serves as a system microcomputer to control the whole system of a car audio. A control program stored in the mask ROM is updated using the FROM incorporated in the second integrated circuit chip.

Abstract: A wind turbine generator system includes, in a nacelle mounted atop a tower, a main shaft that is coupled to a rotor head to which wind turbine blades are attached and that integrally rotates therewith, a gear box accelerating and outputting the rotation speed of the main shaft, a generator driven by the output of the gear box, and a controller that performs cut-out control during strong wind when a measured value from an anemometer is a predetermined level or more. The controller is configured to decide that the anemometer has a fault when a difference of a predetermined level or more occurs between the measured value from the anemometer and an estimated wind speed value obtained from a relationship between a blade-pitch-angle of the wind turbine blades and an output of the generator.

Abstract: The present invention provides a maintenance operation method for a wind turbine generator and a wind turbine generator, which can effectively utilize a phase advance capacitor equipped in the wind turbine generator and contribute to the phase factor improvement of the system side.

Abstract: Provided is a wind turbine generator system that can more accurately perform cut-out control by monitoring the measured value from an anemometer for abnormality. In the wind turbine generator system including, in a nacelle (3) mounted atop a tower, a main shaft that is coupled to a rotor head (4) to which wind turbine blades (5) are attached and that integrally rotates therewith, a gear box (10) accelerating and outputting the rotation speed of the main shaft, a generator (11) driven by the output of the gear box (10), and a controller (20) that performs cut-out control during strong wind when a measured value from an anemometer (7) is a predetermined level or more, the controller (20) is configured to decide that the anemometer has a fault when a difference of a predetermined level or more occurs between the measured value from the anemometer (7) and an estimated wind speed value obtained from a relationship between a blade-pitch-angle of the wind turbine blades (5) and an output of the generator (11).

Abstract: A method and an apparatus for processing audio signals with a directional emphasis by providing other channels besides the left and the right channels. An audio signal processing apparatus is divided into two blocks: a first block for processing digital signals of the left channel and the right channel supplied at each predetermined sampling period and outputting the signals of the left channel, right channel, and other channels which are amplified or decreased to a certain level; and a second block for detecting the level difference between the left channel signal and the right channel signal, and the level difference between the sum and the difference between the channel signals, and generating coefficients for adjusting the amplifying rate of the channels. The result is that the number of bits required for the signal processing can be reduced.
