摘要： In a Viterbi decoder and a Viterbi decoding method, a modulating method and a phase of a carrier wave, employed in a transmitter apparatus can be automatically followed up in a receiver apparatus. The Viterbi decoder is comprised of a phase shifting circuit for shifting a phase of a reproduced carrier wave of a reception signal in response to a phase-shift control signal, thereby producing a phase-shifted signal; a distance calculating circuit for receiving the phase-shifted signal to calculate a square Euclidean distance between a signal point of the phase-shifted signal and a signal point defined in a predetermined modulating method; path metric calculator for calculating a path metric with respect to each of the phases from the calculated square Euclidean distance value; a selector means for selecting a minimum value of the path metric for each of the phases; and a phase-shift control signal producing circuit for producing the phase-shift control signal used to control the phase shifting means in such a manner that the phase of the reproduced carrier wave of the reception signal is set to a phase corresponding to the minimum path metric value.

摘要： An orthogonal frequency division multiplexed (OFDM) demodulation device for demodulating an OFDM signal is disclosed. The device includes a means that demodulates the OFDM signal to produce a baseband OFDM signal. The device also includes a means that detects a carrier frequency offset amount that is a shift amount of a center frequency of the baseband OFDM signal, based on correlation of subcarriers to which a predetermined signal is inserted. Additionally, the device includes a means that controls a frequency of the carrier signal depending on the carrier frequency offset amount. The means that detects the carrier frequency offset amount divides subcarriers into a plurality of groups, calculates a correlation value with respect to an adjacent transmission symbol for each of the groups, adds the correlation values to each other for all the groups, and defines an offset amount assumed when a maximum addition-result value is obtained as the carrier frequency offset amount.

摘要： A rolling bearing is disclosed of which the lifespan is increased by reducing brittle flaking and impression-induced flaking on the raceways of inner and outer races and the rolling elements. Steel containing 1.80-1.89% by weight of chrome (brittle flaking-resistant steel) is subjected to carbonitriding and then to hardening and tempering. The chrome reduces generation of white layers which are aggregates of carbon, thus reducing brittle flaking on e.g. the raceways (1a, 4a) due to the white layers. A residual austenite region (5) that forms when the steel is hardened and tempered increases toughness of the steel surface, thus reducing impression-induced flaking due to foreign matter such as wear dust. By reducing both brittle flaking and impression-induced flaking, it is possible to extend the lifespan of the bearing, and reduce maintenance cost such as the cost for changing lubricating oil.

摘要： A steering lock device includes a lock member that is slidable between a lock position and an unlock position, and a slider that is disposed slidably in a direction perpendicular to a moving direction of the lock member. A sloped portion that is linearly sloped toward the steering shaft along a slide direction of the slider is provided on at least one of the lock member and the slider. The lock member is shifted between the lock position and the unlock position by the sloped portion in response to sliding of the slider. According to the steering lock device, downsizing can be brought due to its short height along a stroke direction of the lock member and cost reduction by commoditization of its main components can be achieved.
