  • Patent number: 10123714
    Abstract: High-accuracy magnetic measurement is performed by efficiently using nitrogen-vacancy pairs in all orientations. A magnetic measurement apparatus includes a diamond crystal and an image sensor. The diamond crystal has nitrogen-vacancy pairs. The image sensor detects the intensities of fluorescence generated by an exciting light applied to the diamond crystal by using a plurality of pixels. The nitrogen-vacancy pairs of the diamond crystal are made to one-to-one correspond to the pixels. The fluorescence generated by one nitrogen-vacancy pair is received by one pixel made to correspond to the nitrogen-vacancy pair.

  • Publication number: 20180243930
    Abstract: Provided is a method of producing an outer blade for a hair cutting device from a material including bars that each have a shape of a rectangular stick and are arranged at predetermined intervals. The material is placed on a base. Next, a first tool having a leading end that has a gradually increasing width in a direction away from the material is used to press at least one part of each of the bars in a direction from a counter base-side first face of each of the bars toward a base-side second face of each of the bars. An edge of the first face of each of the bars is caused to project widthwise and to move toward the second face to be farther from an intermediate part of the first face.

  • Publication number: 20180197799
    Abstract: A semiconductor module includes a case. The case includes a bottom part, a case frame, and a case lid. An inner electrode and a stud bolt are provided inside the case. A head part of the stud bolt is tapered, and a tubular part has an inner diameter that increases downward so as to keep a constant distance from the sides of the head part. With this structure, even if the stud bolt is pulled up, the tubular part can hold down the head part. Therefore, the stud bolt can be prevented from being loosened or detached by the force applied from a terminal fixing screw when an external connection terminal is attached or removed.

  • Patent number: 9846792
    Abstract: A printer and a control method of a printer can print barcodes appropriately according to a given print medium by means of a simple, easy operation. The printer stores a constant preset correction value relationally corresponding to each type of print medium. The printer also stores an added correction value that is optionally input for each specific type of print medium. The preset constant correction value and the added correction value are used to adjust the printed state of the barcode, e.g. to adjust bar widths within the barcode. The print control unit prints barcodes as adjusted using the preset constant correction value stored in the printer storage unit and further adjusted using the added correction value.
