An abutment is obtained that enables an operation of detaching the abutment from a fixture to be readily performed without having a patient open his/her mouth wide while inhibiting accidental ingestion or swallowing of an abutment that comes off. In a dental implantcomprising a fixtureand an abutment, when a fitting recessof the abutmentis fitted onto a fixture headso that a space is formed between a top surfaceof the fixture headand a bottom surfaceof the fitting recess, the fixture headis secured to the fitting recessby a frictional force, and an instrument insertion holefor inserting an instrument for disengaging the securement by the frictional force in the space is formed on a sidewallof the fitting recess

In transmission of digital audio data usingIEEE1394, for example, when the audio data is changed from linear PCM to nonlinear PCM, identifier adding means of the transmitting apparatus inserts a silent identifier and nearly zero data for a specific time, and first identifier distinguishing means of the receiving apparatus changes over the output of data processing selecting means from linear PCM processing side to nonlinear processing side when detecting the silent identifier, thereby preventing generation of noise when changing over the data.

Audio transmitting apparatus and audio receiving apparatus

In a digital audio interface signal demodulating apparatus (DDAp) that adds a preamble (PA) and additional information (V, U, C, P) to a digital audio signal (Sda) and demodulates into a digital audio interface signal (Sdai) after subjected to bi-phase modulation for transmission, based on both of positive and negative edges of a reference clock (Src) having a frequency higher than twice a minimum inverse frequency (1/T) of said digital audio interface signal (Sdai) and not necessarily synchronizing with said digital audio interface signal (Sdai), a modulation period (nT) of the digital audio interface signal (Sdai) is decided, and a decision signal (Sj) is generated. Furthermore, based on the decision signal (Sj), the: preamble (PA) is detected, and based on the detected preamble (PA), an audio signal (Sda) is obtained from said decision signal (Sj) through demodulation.

There is provided an audio signal subband encoder which attains improved quality of sound by controlling allocation of the number of quantization bits to subband signals on the basis of an evaluation function combining the noise-to-mask ratio criterion with noise-to-signal ratio criterion in order to lessen the influence of the application error of the auditory masking rule such as the aliasing distortion of subband filters.

Audio signal subband encoder

An audio subband encoded signal decoder which, when an error occurs in an audio subband encoded signal of a plurality of pieces of data, conceals the error in accordance with the contents of the data involving the error and the occurrence of the error in consideration of the degree of influence on a possible reproduced sound quality to thereby improve the sound quality.

This invention relates to a time code recording and reproducing apparatus for recording and reproducing time codes corresponding to a digital signal. Time code converting means (100) converts a first time code into a second time code. A frame phase which occurs during the recording of input information is determined by frame timing generating means. A phase difference between a frame of the second time code and a recording frame is detected by phase difference detecting means (103). Phase difference correcting means (104) outputs a third time code on the basis of the detected phase difference. The input information is recorded together with the third time code. Thereby, the recording can be performed while the relation of the correspondence between the input information and the time code is held. In addition, the reproduction can be performed.
