  • Publication number: 20200285003
    Abstract: A photoelectric conversion module 1 includes a photoelectric conversion element 20 which has a light receiving/emitting unit 25 to receive or emit light; an optical fiber 30 which has one end portion fixed to the photoelectric conversion element 20; and a light transmitting resin 41 which fixes the one end portion of the optical fiber 30 and the photoelectric conversion element 20, reflects light by a predetermined region 42 of a surface thereof, and optically couples a core 31 of the optical fiber 30 and the light receiving/emitting unit 25. An outer circumferential surface of a clad 32 at the one end portion of the optical fiber 30 contacts an element surface 21 from which the light receiving/emitting unit 25 is exposed at a position not overlapping a center of the light receiving/emitting unit 25 in the photoelectric conversion element 20.

  • Publication number: 20200250586
    Abstract: A first sample acquisition unit acquires a parameter sample from a prior distribution. A function execution unit acquires data from a distribution by supplying the sample to a function. A degree-of-similarity calculation unit calculates the degree of similarity between the data and correct data using a kernel function. A kernel mean construction unit constructs a kernel mean of a posterior distribution from the degree of similarity, the sample, and the kernel function. A second sample acquisition unit acquires a new parameter sample from the kernel mean and the kernel function. A sample evaluation unit determines whether the difference between new data obtained by supplying one sample selected from the new samples to the function and the correct data is less than a prescribed threshold value. When it is determined that the difference is less than the prescribed threshold value, the sample evaluation unit estimates the selected sample as a parameter.

  • Patent number: 10446966
    Abstract: A spring contact to which a compressive load is to be imposed includes a base, a first elastic arm of a helical shape, a first contact, a second elastic arm of a helical shape, and a second contact. The first elastic arm includes a first fixed end supported on the base and a first end portion at a free end. The first contact is provided at the first end portion and protruding in a direction from which the load acts. The second elastic arm includes a second fixed end supported on the base and a second end portion at a free end. The second contact is provided at the second end portion. The second contact is placed independent of the first contact and protrudes in the direction from which the load acts.

  • Patent number: 10033125
    Abstract: An interior body includes a spring portion, a movable portion, and a fixing portion, which are integrated together and formed by bending a first metal plate having a high modulus of elasticity. An exterior body is formed by bending a second metal plate having low electric resistance. A movable portion of the interior body includes a contact portion and elastic arms. Each of the elastic arms includes, at its tip portion, an elastically pressing portion elastically pressed against a tubular internal surface of the exterior body.

  • Patent number: 10014604
    Abstract: An interior body is housed in a tubular exterior body. The interior body includes a spring portion, a movable portion, and a fixing portion, which are integrated together. Elastic arms are disposed on the movable portion so as to extend downward. Each elastic arm includes, at a lower end portion, an elastically pressing portion, which is elastically pressed against a tubular internal surface of the exterior body. Since the elastically pressing portion is elastically pressed against the exterior body, electric signals are more likely to flow between the movable portion and the exterior body and more likely to be prevented from leaking to the spring portion.
