    摘要： A position detection device includes a magnetic scale and a magnetic sensor. The magnetic scale includes a plurality of magnets arranged along a first reference direction. The magnetic sensor includes a plurality of detectors that detect a composite magnetic field. The plurality of detectors are each arranged to satisfy AG=N(M−W)/(n−1), where n is the number of magnets of the magnetic scale, M is a distance from a first end to a second end, W is the width of each of the plurality of magnets and is greater than 0 and less than or equal to M/n, AG is a gap between each of the plurality of magnets and each of the plurality of detectors in a second reference direction, and N is a number greater than or equal to 0.4 and less than or equal to 2.

    摘要： Technologies are provided for microelectromechanical microphones that can be robust to substantial pressure changes in the environment in which the micromechanical microphones operate. In some embodiments, a microelectromechanical microphone device can include a rigid plate defining multiple openings that permit passage of a pressure wave. The microelectromechanical microphone device also includes a stiffener member integrated into the rigid plate. The stiffener member causes stress to be distributed within the rigid plate in response to the pressure wave inducing deformation of the rigid plate.

    摘要： An ultrasonic device includes a case, a piezoelectric element, a sound absorbing material, and a vibration-proof material. The case defines a housing space. The piezoelectric element is disposed in the housing space. The sound absorbing material is disposed on the piezoelectric element and is made of a foaming material. The vibration-proof material is disposed around the sound absorbing material and is in contact with an inner face of the case. Between the piezoelectric element and the sound absorbing material, a first space is formed.

    摘要： The optical coupler is a multimode interference type optical coupler that couples a plurality of laser lights of different wavelengths. The optical coupler includes an optical coupling main body, two input taper portions which are tapered input ports that are disposed on the input side of the optical coupling main body and of which the width of each becomes narrower as it is away from a connection end with the optical coupling main body, and one output taper portion which is a tapered output port that is disposed on the output side of the optical coupling main body and of which the width becomes narrower as it is away from a connection end with the optical coupling main body.
