Abstract: A tread portion 2 includes four circumferential grooves 3 and five land portions 4. Each of the five land portions 4 is provided with no groove having a groove width greater than 2.0 mm, and is provided with only sipes 9. The four circumferential grooves 3 include a shoulder circumferential groove 5. The five land portions 4 include a shoulder land portion 11 and a middle land portion 13. The middle land portion 13 is provided with a plurality of middle sipes 30. The shoulder land portion 11 is provided with a plurality of shoulder sipes 20 each extending from the shoulder circumferential groove 5 to a position beyond a tread end. At least one of the shoulder sipes 20 includes an inclined portion 21. A maximum angle of the inclined portion 21 with respect to a tire axial direction is not greater than a maximum angle of the middle sipe 30 with respect to the tire axial direction.

Abstract: Provided is a tire including a tread portion. The tread portion can include three circumferential grooves and four land portions. The circumferential grooves can include two shoulder circumferential grooves and one crown circumferential groove. The land portions can include two shoulder land portions and two middle land portions. The two middle land portions can each include a circumferential sipe, a plurality of first middle lateral grooves, and a plurality of second middle lateral grooves. The two shoulder land portions can each include a plurality of shoulder lateral grooves extending from a tread end and terminating in the shoulder land portion.

Abstract: A tire for which a mounting direction to a vehicle is specified, has a tread portion axially divided into five land portions each provided with sipes. The five land portions are a first shoulder land portion, a first middle land portion, a crown land portion, a second middle land portion, and a second shoulder land portion having ground contacting surface widths W1s, W1m, Wc, W2m and W2s, respectively, which satisfy the following condition: W1s>W1m>Wc>W2m=>W2s under a 50% load state of the tire.

Abstract: There is provided a receiving apparatus (1) that comprises; a receiving unit (4) for receiving a frequency division multiplexing signal to output a receiving signal; a first demodulating unit (7) for demodulating a receiving signal based on 1 segment broadcasting and 3 segment broadcasting to output a first carrier; a second demodulating unit (8) for demodulating a receiving signal based on the 1 segment broadcasting to output a second carrier; a judging unit (9) for judging whether a receiving signal is the 1 segment broadcasting or the 3 segment broadcasting; and a combining/selecting unit (10) for combining or selecting the first carrier and the second carrier. In case of the 1 segment broadcasting, the combining/selecting unit (10) combines or selects the first carrier and the second carrier. In case of the 3 segment broadcasting, the combining/selecting unit (10) selects the first carrier.

Abstract: Disposed are a signal conversion circuit for converting a received signal point into a converted signal point in a first quadrant on a complex plane and for outputting a quadrant signal representative of a quadrant where the received signal point is situated, a branch metric arithmetic circuit for deciding the maximum likelihood between the converted signal point and a subset signal point and for outputting a branch metric and a subset decision signal, an ACS (Add Compare Selection) circuit for performing arithmetic operations to compute, from the branch metric, a path metric according to a trellis diagram and for outputting a path selection signal for selection of a path having a high likelihood, a first, a second, and a third storage circuit for storing the quadrant signal, the subset decision signal, and the path selection signal, respectively, a traceback circuit for performing traceback of these stored signals and for outputting a quadrant decoding signal, a subset decoding signal, and an encoded bit dec
