Abstract: Encoding efficiency for attribute information in point cloud information is improved. A point cloud encoding device includes a subsampling unit configured to preserve chroma signals of some points in a point cloud to be encoded and discard chroma signals of remaining points other than those points, and an attribute information encoding unit configured to encode the chroma signals of those points in the point cloud to be encoded and luma signals of all points.

Abstract: A point cloud coding device includes an interpolation unit configured to perform an interpolation process on a reconstructed point cloud of a coded frame with respect to attribute information in point cloud information and generating a reference frame of fractional precision, a motion estimation unit configured to perform motion estimation between the reference frame of fractional precision and the frame of integer precision to generate motion information, a prediction unit configured to generate a predicted value on the basis of the motion information, and an entropy coding unit configured to entropy-code the difference between a point cloud of the frame and the predicted value.

Abstract: A rotation transmitter includes a first member, a second member, and an intermediate member. The first member is connected to the intermediate member by a first rotary mechanism. The second member is connected to the intermediate member by a second rotary mechanism. A second rotary mechanism includes: a second radial pin supported by a first one of the second member and the intermediate member; a plurality of pairs of rollers disposed at different positions of the second radial pin and each of the pairs of rollers holding the second radial pin therebetween; axial pins supporting the respective rollers while supported by a second one of the second member and the intermediate member; and stroke bearings respectively interposed between the rollers and the axial pins and supporting the rollers so that the rollers are rotatable around the axial pins and movable in a direction of the rotation axis.

Abstract: A method of placing a work piece on a measuring device in which a work piece is placed on a table of a measuring device is provided. The method includes: using a retainer capable of holding the work piece above the table and a lifting/lowering device lifting and lowering a top surface of the table; holding the work piece above the table with the retainer; lifting the top surface of the table with the lifting/lowering device to bring the top surface of the table into contact with a bottom surface of the work piece; and, after a load of the work piece is borne by the table, releasing the hold of the retainer on the work piece.

Abstract: A receiver device which is small in scale of circuit configuration yet capable of detecting an error between symbol timing of a received signal and that generated therein and also restraining an error signal from varying due to variation in input level of the received signal. A delayer delays the received signal for one effective symbol period, a correlator calculates a correlation signal from the product of the received signal and the delayed signal, and an integrator calculates an integral value of the correlation signal. First and second accumulative adders accumulatively add up the integral values over respective predetermined periods before and after symbol start timing generated within the receiver device. An error signal generator generates an error signal by normalizing the difference between first and second sums obtained from the first and second accumulative adders, respectively, by means of the sum total of the first and second sums.
