  • Patent number: 10018420
    Abstract: The present invention provides a heat treatment jig. A metal wire as a heat treatment target is to be wound around the jig. The jig comprises a cylindrical tubular body whose outer wall surface has a helical groove formed along a circumferential direction to wind the metal wire. A depth of the groove is larger than a length at which the metal wire will isolate from the groove when the metal wire wound along the groove at room temperature is thermally expanded by being heated to a predetermined heat treatment temperature.

  • Patent number: 10016893
    Abstract: A robot hand controlling method executes calculating a position and changing grip force when the grip force for gripping a work W is to be changed in a state that fingers are gripping the work W with first grip force. In the calculating the position, the hand controlling unit uses a correlation value indicating a relationship between the grip force of the fingers and position of fixing portions, the first grip force, and second grip force that is a target value of the grip force to calculate the position of the fixing portions in gripping the work W with the second grip force. In the changing the grip force, the hand controlling unit drives a motor by calculating a driving quantity of the motor necessary for moving the fingers to the calculated position of the fixing portions.

  • Patent number: 10019212
    Abstract: A printing apparatus that is capable of reducing downtime caused by software update. A printing apparatus downloads update software for updating software installed therein, and updates the installed software using the downloaded update software. The update software is downloaded by background processing. It is determined whether or not predetermined processing is being performed when the update software is decompressed. When it is determined that the predetermined processing is not being performed, the downloaded update software is decompressed by background processing, and the installed software is updated using the decompressed update software.

  • Patent number: 10021483
    Abstract: A noise signal is estimated based on a captured audio signal captured from a sound capture unit. It is determined whether the estimated noise signal thus estimated is in a noiseless state. If it is determined that the estimated noise signal is in the noiseless state, the captured audio signal is analyzed as a target sound signal, and a characteristic obtained by the analysis is learned and modeled, thereby generating a target sound model.

  • Patent number: 10019814
    Abstract: A method of determining luma values from 4:4:4 RGB video data for encoding chroma downsampled 4:2:0 YCbCr video data into a bitstream. Initial coefficents are determined for a region of a colour space the region being one of a plurality of regions located in the colour space and each region having a plurality of associated coefficients. The determined initial coefficients are applied to an initial image to produce a test image, the test image being a chroma downsampled 4:2:0 YCbCr version of the initial image. A measure of quality is determined by comparing the initial image and the test image. The determined initial coefficients are modified to increase the determined measure of quality. Luma values are determined from 4:4:4 RGB video data for encoding chroma downsampled 4:2:0 YCbCr video data into a bitstream using the modified coefficients.
