  • Patent number: 10105063
    Abstract: A flash lamp 32 excites a laser rod 31. A Q switch 35 which changes the loss of the optical resonator according to the voltage applied is inserted on the optical path of a pair of mirrors 33 and 34 forming the optical resonator. An optical path shutter 39 is provided on the optical path of laser emission light. In a first operation mode in which laser emission is performed, the optical path shutter 39 is opened and the voltage applied to the Q switch 35 is changed from a high voltage to, for example, 0 V to emit pulsed laser light after the flash lamp 32 excites the laser rod 31. In a second operation mode in which the laser emission is interrupted and waited for, the optical path shutter 39 is closed and the voltage applied to the Q switch 35 is, for example, 0 V.

  • Publication number: 20180002919
    Abstract: A soundproof structure includes one or more soundproof cells. Each of the one or more soundproof cells includes a frame having a hole portion, a vibratable film fixed to the frame so as to cover the hole portion, and one or more through holes drilled in the film. Both end portions of the hole portion of the frame are not closed, and the frame and the film are formed of the same material and are integrally formed. Therefore, it is possible to provide a soundproof structure and a soundproof structure manufacturing method capable of not only stably insulating sound due to increased resistance to environmental change or aging but also avoiding problems in manufacturing, such as uniform adhesion or bonding of a film to a frame.
