  • Publication number: 20190001466
    Abstract: An annular grinding stone is provided which includes a cutting edge with a plurality of V-shaped slits defined in an outer circumferential portion thereof is provided. Each of the V-shaped slits is defined by a first surface and a second surface of the annular cutting edge. The first surface is positioned rearwardly of the second surface with respect to a direction along which the annular grinding stone rotates, and the second surface is positioned forwardly of the first surface with respect to the direction along which the annular grinding stone rotates. The first surface lies perpendicularly to the direction along which the annular grinding stone rotates at a radially outer end thereof and parallel to thicknesswise directions of the annular cutting edge. The second surface is inclined with respect to the first surface at an angle ranging from 30° to 60°.

  • Patent number: 10110996
    Abstract: The DC detection circuit includes: a OR circuit configured to generate a logical OR flag on the basis of logical OR of values of X bits from a (MSB-1)th bit to a (MSB-X)th bit of input data; a NAND circuit configured to generate a NAND flag on the basis of a NAND of values of X bits from the (MSB-1)th bit to the (MSB-X)th bit of the input data; a counter configured to count up and a counter value which outputs a DC detection flag if a counter value is exceeds predetermined set value on the basis of the MSB and any one of the logical OR flags of NAND flags. Accordingly, safety can be secured by detecting whether the DC data is included in the input PCM data, and thereby preventing degradation and breakage of the loudspeaker etc. due to the DC data.

  • Patent number: 9516530
    Abstract: A CQI control unit 401 inputs, to a subchannel selecting unit 402, subchannel estimation values for report bands which are based on control information received from a control information separating unit 221, at report timings based on the control information. The subchannel selecting unit 402 selects a predetermined number (M) of subchannels on the basis of the received subchannel estimation values, and inputs information indicating the selected subchannels and the qualities of the selected channels to a CQI constructing unit 403. Based on a predetermined format, the CQI constructing unit 403 constructs CQIs by using the qualities of the selected channels and the information indicating the selected channels, and inputs the CQIs to the coding unit 210. Here, as the channel quality, an average value of each of SNR, SINR, and CINR of subcarriers belonging to the subchannel is used.
