  • Patent number: 10584853
    Abstract: A light-emitting device includes a plurality of semiconductor laser elements including a first semiconductor laser element, and a plurality of reflectors including a first reflector for reflecting light emitted from the first semiconductor laser element, each of reflectors reflecting light emitted from corresponding one of the plurality of semiconductor laser elements. Light emitted from the first semiconductor laser element passes through a gap between two of the plurality of reflectors excluding the first reflector and reaches the first reflector. Lights emitted from the plurality of semiconductor laser elements are extracted in a direction different than an incident direction thereof toward the plurality of reflectors.

  • Publication number: 20190195704
    Abstract: A force detector includes a support, fluid bags, a contact portion, a detector, and a computer. The contact portion is opposite to a side on which the fluid bags are in contact with the support and is adjacent to the fluid bags. The computer obtains information regarding the internal pressures of the fluid bags from the detector. Upon application of an external force to the contact portion from an object, the computer calculates a force acting in a tangential direction on a contact surface between the object and the contact portion based on a difference between the internal pressures of the fluid bags.
