  • Patent number: 11924402
    Abstract: To provide an information processing apparatus, an information processing method, and a program for restraining a burden on a user who observes a three-dimensional image. Therefore, a display control unit performs display control to cause a three-dimensional image to be displayed so that a first plane surface parallel to a horizontal plane in a real space is observed in an area based on a distance between a lower end and an upper end of a display surface on which a display unit displays the three-dimensional image and an angle between the horizontal plane and the display surface.

  • Patent number: 11024451
    Abstract: A multilayer coil component includes coil conductors including silver planar conductors and ferrite layers containing copper and stacked with the coil conductors and the planar conductors interposed therebetween. The coil conductors define a portion of a coil with a winding axis extending in a lamination direction. The planar conductors are arranged in the lamination direction at a position on an upper side of the coil so that each of principal surfaces thereof faces in the lamination direction and a specific region of the principal surface overlaps with the coil when viewed from the lamination direction. Each of the planar conductors includes first through holes penetrating the principal surface in the lamination direction in the specific region.

  • Patent number: 9953757
    Abstract: In a laminated coil component include coil conductors are respectively included on magnetic layers and a carbon paste is included on a magnetic layer. The coil conductors include a partial coil conductor and a partial coil conductor respectively corresponding to an outer side portion circle and an inner side portion circle defining two circles. A width of the carbon paste at least partially overlaps an interval between the outer side portion circle and the inner side portion circle defining the two circles, and extends circularly along the two circles. The carbon paste is shifted to the interval between the outer side portion circle and the inner side portion circle defining the two circles at the time of pressure-bonding the magnetic layers. The carbon paste vanishes when being calcined to define an air gap.

  • Patent number: 9601253
    Abstract: Provided is a laminated-type inductance device capable of reducing the number of layers for sandwiching a non-magnetic body layer and enhancing direct-current superposition characteristics without intentionally providing a space. In a conductive pattern, portions of the outer circumferential section thereof adjacent to end surface electrodes are respectively recessed toward the inside of the pattern when viewed from above. In other words, line widths are narrower at the above portions. Further, non-magnetic paste is formed between the end surface electrode and the outer circumferential section of the conductive pattern at each of the portions where the line width is narrower. By applying the non-negative paste in a space between the conductive pattern and the end surface electrode, the portion where the non-magnetic paste is applied has the same function as in a case where the non-magnetic ferrite layer is inserted therein.

  • Patent number: 9466416
    Abstract: A multilayer inductor device in which parasitic inductance is made smaller while preventing increase in a mounting area of the device and complexity of a wiring pattern, and a manufacturing method of the stated multilayer inductor device. An outer electrode and a terminal electrode are connected to each other through a via hole. A side surface of a non-magnetic member forms a part of an end surface of the device, while the other side surface thereof being in contact with the via hole. A side surface of the via hole that makes contact with the non-magnetic member is opened, which prevents the parasitic inductance from being increased. The via hole being provided in an arbitrary position makes it possible to prevent the wiring pattern from being complicated and a mounting area of the device from being increased.
