Abstract: A cache controller is connected to a processor and a main memory. The cache controller is also connected to a cache memory that can read and write at a speed higher than the main memory. The cache memory is provided with a plurality of cache lines that include a tag area storing an address on the main memory, a capacity area storing a capacity value of a cache block, and a cache block. When a read request is executed from the processor to the main memory, the cache controller checks whether the requested data is present in the cache memory or not. A cache capacity determination unit determines a capacity value for the cache block and supplies to a capacity area.

Abstract: An error voltage Verr, as amplified by an amplifier, and an input voltage Vin, are multiplied together by a multiplier to generate a first threshold value signal Vth1, which is in phase with and similar in waveform to the input voltage Vin, and proportional in amplitude to the error voltage Verr. A second threshold value signal Vth2 is generated from the first threshold value signal Vth1 by a series circuit of a diode and a resistor. The power factor is increased by on/off-control of a switching element via a drive circuit, so that a current detection signal Vi, which is detected by a resistor and corresponds to an input current, falls between the two threshold value signals Vth1 and Vth2. Since the off time is not fixed, the noise spectrum is spread and increase of the switching frequency is suppressed. Noise reduction thus can be attained.

Abstract: The present invention provides preventive, ameliorating, and/or therapeutic agents for diseases caused by a disturbed balance between bone formation and bone resorption. The decoys of the present invention induce normal bone metabolism by inhibiting the differentiation-inducing factors of cells involved in bone metabolism. For example, bone resorption can be controlled by using a decoy of the present invention to inhibit NF-?B, a transcriptional regulatory factor that regulates osteoclast differentiation. This method uses a mechanism different from those of previous pharmaceutical agents; therefore, one can expect it to be effective for cases in which existing pharmaceutical agents were not effective.

Each of the converting processes is equivalent to performing a first mask process, a non-linear conversion predetermined for an encoding or a decoding and a second mask process.

Abstract: Five infrared sensors are located in different height positions between respective main bodies 10A to 10H, and all of these infrared sensors transmit and receive 35 infrared rays pulse-coded in conformity with a start-stop system. In addition, these pulse-coded infrared rays have the signal width of, for example, 450 ?s, and are serially transmitted with a predetermined delay time in a period of 20 ms by a delayed synchronizing-signal. Intrusion surveillance is performed by identifying the pulse codes of these infrared rays. According to this, since not only interference among a plurality of infrared sensors is prevented, but also infrared rays are outputted in a short time, the occurrence of false alarms etc. decreases remarkably.
