The present invention relates to a dual-layer sintered valve seat ring having high stiffness and strength. The features of such ring are: fusion infiltration of Cu into the pores of a ferrous sintered body; hard alloy particles dispersed in the matrix of the valve seat body; the composition of the base and the ferrous sintered body; high density; and, diffusion of an alloying element of the hard particles around them and into the matrix.

A steering apparatus having a stationary bracket fixed to a vehicle body including a pair of first side plates; a receiving portion provided on the steering column for receiving one end of a conductive member; a pair of second side plates; a conductive cylindrical shaft secured between the pair of first side plates and inserted through the pair of the second side plates; and a plate-shaped conductive member interposed between the receiving portion and an outer peripheral surface of the cylindrical shaft. The conductive member includes first and second bow springs that fit the cylindrical shaft resiliently. The first bow spring is interposed between the second bow spring and the receiving portion, a first contact portion of the second bow spring is pressed to the outer peripheral surface of the cylindrical shaft, and a second contact portion of the first bow spring is pressed to the receiving portion.

An audio decoder which reproduces original signals from a bit stream including (i) a downmix signal of the original signals, and (ii) supplementary information indicating a gain ratio D and phase difference θ between the original signals. The audio decoder includes: a decoding unit extracting the downmix signal; a transformation unit transforming the extracted downmix signal into a frequency domain signal; a phase rotator determination unit determining two phase rotators having, as the phase rotation angles, angles α and β respectively obtained by dividing a contained angle by a diagonal of a parallelogram; a separation unit separating the frequency domain signal into two separation signals respectively indicating angles α and β as phase differences between the signals and the decoded downmix signal; and an inverse transformation unit inversely transforming the respective two separation signals into time domain signals so as to reproduce the two audio signals.

An audio encoder, generating a stereo signal based on a multi-channel signal, includes a downmix unit for downmixing a multi-channel signal exceeding two channels to a two-channel stereo signal, a first coding unit for generating a first coded signal by coding the downmixed stereo signal, a second coding unit for generating a second coded signal by coding information to restore the downmixed stereo signal to a multi-channel signal, a code size calculating unit for calculating a code size of the second coded signal, and a first multiplexing unit for multiplexing the calculated code size in either the first coded signal or the second coded signal. Accordingly a decoder is able to easily extract a coded signal of the multi-channel signal based on the code size, and the decoder reproducing only the downmixed signal can be configured inexpensively.

An acoustic signal encoding device for down-mixing at different ratios to encode a multichannel signal with a small number of channels, and an acoustic signal decoding device for decoding the signal encoded by the acoustic signal encoding device. In these devices, weighting means (103) in the acoustic signal encoding device (100) weights input signals of two channels individually according to a down-mixing coefficient thereby to calculate the level difference of the signals of two channels weighted by a level difference calculation unit (104). A separating unit (202) in the acoustic signal decoding device (200) separates the down-mixed signals into signals of two channels with the level difference information weighted.

A friction material for a synchronizer ring comprises (A) a petroleum coke with an ash content of 0.1 mass % to 8 mass % or (B) a pitch coke with an ash content of 0.1 mass % to 8 mass %, more preferably (C) a calcined petroleum coke with an ash content of 0.1 mass % to 1 mass % or (D) a foundry coke with an ash content of 5 mass % to 8 mass %. The friction material is effectively used for a synchronizer ring requiring high coefficient of dynamic friction.
摘要:
A curved leaf spring which is a first urging member surrounds an outer wheel of a second bearing, and urges, through the second bearing, a second end of a worm shaft in a direction in which the distance between the center of the worm shaft and the center of a worm wheel is shortened. A second urging member includes an annular support member received by an end surface of the outer wheel and a plurality of elastic pins extending in a direction in parallel with the axial direction of a support member. The elastic pins have fixed ends fixed to the support member and free ends that come into elastic contact with an end wall of a housing.
