  • Patent number: 12132078
    Abstract: To provide a thin film capacitor having high adhesion performance with respect to a multilayer substrate. A thin film capacitor includes: a metal foil having a roughened upper surface; a dielectric film covering the upper surface of the metal foil and having an opening through which the metal foil is partly exposed; a first electrode layer contacting the metal foil through the opening; and a second electrode layer contacting the dielectric film without contacting the metal foil. A height of the first electrode layer is lower than a height of the second electrode layer. This enhances adhesion performance when the thin film capacitor is embedded in a multilayer substrate and improves ESR characteristics.

  • Patent number: 12116052
    Abstract: Control calculation units of a back system in each actuator operate by a collaborative drive mode in which a torque is output to a motor drive unit by using an information transmitted and received mutually by a communication between the systems in common. Cooperative control calculation units in a reaction force actuator and a turning actuator can operate in cooperation with each other based on the information transmitted and received mutually by a communication between actuators. A communication between adjacent systems and a communication between adjacent actuators are restored, when a focus control calculation unit is restored, after the focus control calculation unit is stopped during operation and at least one of the communication between adjacent systems or the communication between adjacent actuators is interrupted.

  • Publication number: 20240310471
    Abstract: The present disclosure relates to an information processing device, an information processing method, and a program each capable of measuring a position and a posture by using sound without bringing discomfort to a user. A spread code signal emitted from each of multiple sound output blocks present at known positions, shifted to a frequency band that is not easily perceivable for a human sense of hearing, and based on a spread code to which spread spectrum modulation has been applied is received. The received spread code signal of a sound signal is reversely shifted. The own absolute position and the own absolute posture are calculated on the basis of the reversely shifted spread code signal, and angular velocity and acceleration detected by an IMU. The present disclosure is applicable to a game controller and an HMD.

    Abstract: A light emitting diode lamp is composed of a light emitting diode, a band-pass filter and a light angle adjuster. The filter has a light cutoff function to cut off a light ray with a specific wavelength. The light angle adjuster allows the light rays emitted from the diode to be incident on the filter at incident angles of less than or equal to a maximum incident angle up to which the filter is capable of exerting the light cutoff function. The light angle adjuster is a reflector. The diode is mounted to a bottom portion. The filter is mounted to an opening. On an imaginary cross section including the optical axis, an angle formed between the optical axis and a straight line is less than or equal to the maximum incident angle, the straight line connects the emission center and an edge of the opening.
