    摘要: An active noise reduction device for reducing the noise produced by cooling fans in a computer. The active noise reduction device comprises a duct mounted on the casing of the computer and having at least one air passage. One end of the passage communicates with the interior of the casing near the cooling fans and the other end is open to the atmosphere. A first microphone is arranged in the duct near the first end opening for detecting noise, and a second microphone is arranged in the duct near the second end opening. A speaker is arranged in the duct near the second opening, and a controller controls the speaker in response to outputs of the first and second microphones for reducing the noise produced in the casing. The speaker makes a sound having a reverse phase to that of the noise produced in the computer and the speaker sound is superimposed on the noise.

    摘要: A signal suppressing apparatus for suppressing undesired signal components, in which a first filter electrically simulating a propagation system A of a physical phenomena such as a sound, vibration, electricity, etc. is mounted; a signal having a correlation to the signal to be input to the propagation system A is input to this first filter; and the output of the first filter exerts an influence upon the signal passing the propagation system A to make the passed signal approximate the intended value, wherein the first filter is split into a plurality of filters, each of which is composed by a discrete DSP, outputs are individually calculated in the split individual filters, and the individual calculation results are tabulated, whereby a value the same as the value obtained where the calculation is made without splitting of the first filter is obtained. This enables high speed signal processing even if a high speed DSP is not used.

    摘要: An image forming apparatus uses a switching element to switch current flowing to an excitation coil, so that a heating layer in a fixing member produces heat that fixes an image to a transported sheet. Based on a change in temperature of the switching element over time, a prediction unit determines, at a predetermined first time point, a predicted temperature of the switching element at a second time point at which a tip of the sheet is scheduled to arrive at the fixing member. When the predicted temperature is at least a predetermined value, a control unit controls power supplied to the excitation coil by restricting switching of the switching element and lifting the restriction, so that by the second time point the detected temperature of the fixing member reaches a temperature necessary for fixing.

    摘要: Provided is a molten salt battery whose cycle life is improved by using an electrolyte that is unlikely to cause corrosion of aluminum. In the molten salt battery of the present invention, the total concentration of iron ions and nickel ions contained as impurities in the electrolyte composed of a molten salt is set to be 0.1% by weight or less, preferably 0.01% by weight or less. Because of the low total concentration of iron ions and nickel ions contained in the electrolyte, corrosion of the electrode current collector composed of aluminum is inhibited, and the cycle life of the molten salt battery is improved.
