  • Patent number: 10413832
    Abstract: A game control method, game server, and program can increase variations on methods for acquiring items, increase the predictability of acquisition of an item with a high rarity value or the like, and heighten interest in the game. Included are the steps of presenting a communication terminal, connected over a communication line, with acquirable item information that, for each item type, includes a total count and an acquisition count or a non-acquisition count of items when receiving, from the communication terminal, a request to present information related to items acquirable by the communication terminal, determining an item to provide to the communication terminal when receiving an item acquisition request from the communication terminal, and changing the acquirable item information when receiving a reset request from the communication terminal.

  • Publication number: 20190271809
    Abstract: An optical modulator capable of curbing deterioration of transmission properties due to deformation of a housing is provided. Provided is an optical modulator including a substrate (10) on which an optical waveguide (20) is formed and a housing (30) that accommodates the substrate, in which the optical waveguide includes mode conversion branching portions (21, 22) which convert a mode of light waves propagating through the optical waveguide and branch the light waves, a mounting portion (32) protruding from a surface (31) inside the housing and holding the substrate is formed, and the substrate is fixed to the mounting portion in an arrangement in which a fixed end (33) between the substrate and the mounting portion is positioned outside a region including the mode conversion branching portions when the substrate is seen in a plan view.

  • Patent number: 10324142
    Abstract: A diamond crystal according to the present invention has an NV region containing a complex (NV center) of nitrogen substituted with a carbon atom and a vacancy located adjacent to the nitrogen, on a surface or in the vicinity of the surface, wherein the NV region has a donor concentration equal to or higher than the concentration of the NV centers, or a crystal of the NV region is a {111} face or a face having an off-angle that is ±10 degrees or less against the {111} face, and a principal axis of the NV center is a <111> axis that is perpendicular to the {111} face. Such a diamond crystal enables almost 100% of the NV center to be a state (NV?) of having a negative electric charge, and spin states of the NV? centers to be aligned in one direction.

  • Patent number: 10291198
    Abstract: A matching device includes: a directional coupler that detects a traveling wave and a reflected wave; a matching circuit that has a first variable capacitance capacitor, a second variable capacitance capacitor and an inductance; and a control unit that calculates a reflection coefficient based on the traveling wave and the reflected wave and controls a capacitance value VC1 of the first variable capacitance capacitor and a capacitance value VC2 of the second variable capacitance capacitor. The control unit changes VC2 such that VC2 moves toward a circle drawn by the trajectory of the reflection coefficient passing through a matching point on a Smith chart, fine-tunes VC1 on the basis of a predicted intersection point with the circle, and when the distance between the calculated reflection coefficient and the circle becomes a predetermined value or less, changes VC1 such that the calculated reflection coefficient approaches zero, and fine-tunes VC2.

  • Publication number: 20190036507
    Abstract: A matching device includes a directional coupler, a matching circuit including a first variable capacitance capacitor and a second variable capacitance capacitor, and a control unit. The control unit calculates a reflection coefficient on the basis of a forward power and a reflected power that are detected by the directional coupler, changes the capacitance value of the first variable capacitance capacitor and the capacitance value of the second variable capacitance capacitor such that the calculated reflection coefficient becomes smaller, and makes the cycle of calculation of the set values of the capacitance value of the first variable capacitance capacitor and the capacitance value of the second variable capacitance capacitor shorter than the cycle of acquisition of the capacitance value of the first variable capacitance capacitor and the capacitance value of the second variable capacitance capacitor.

  • Publication number: 20180191324
    Abstract: A matching box comprises a directional coupler that detects forward waves and reflected waves; a matching circuit having a first variable capacitance capacitor, a second variable capacitance capacitor, and inductance; and a control unit that calculates a reflection coefficient on the basis of the forward waves and the reflected waves, and controls a capacitance value VC1 of the first variable capacitance capacitor and a capacitance value VC2 of the second variable capacitance capacitor, wherein the control unit changes VC2 if the distance between a matching circle drawn by the trajectory of the reflection coefficient passing through a matching point on a Smith chart, and the calculated reflection coefficient is greater than a prescribed value, and changes VC1 if such distance is set to be no greater than the prescribed value and when the value of such distance becomes no greater than the prescribed value, thereby reducing the reflection coefficient.

  • Patent number: 9876482
    Abstract: A matching unit includes a directional coupler for detecting a travelling wave and a reflected wave; a matching circuit including a first variable capacitance capacitor, a second variable capacitance capacitor and an inductance; and a control unit for controlling VC1 and VC2 of the first and the second variable capacitance capacitor by calculating a reflection coefficient based on the travelling wave and the reflected wave. When a distance between the calculated reflection coefficient and a circle described by a trace of the reflection coefficient which passes through a matching point on a Smith chart is greater than a predetermined value, the control unit changes VC2 of the second variable capacitance capacitor and the calculated reflection coefficient to make the distance within the predetermined value. When the distance becomes within the predetermined value, the control unit changes VC1 of the first variable capacitance capacitor and makes the calculated reflection coefficient smaller.
