Patent number: 9984865Abstract: In a light-emitting sealed body, a metal structure (electron emission structure) containing an easily electron-emitting material is used, so that it is not necessary to perform feeding for discharge between electrodes. Therefore, a feeding member does not need to be connected to the metal structure from the outside of a bulb. In addition, in the light-emitting sealed body, the metal structure is disposed in an internal space S of the bulb and a positioning unit of the metal structure is disposed only in the bulb. Therefore, in the light-emitting sealed body, the metal structure and the positioning unit do not penetrate the bulb and are not buried in the bulb and weakened portions are not formed in the bulb made of glass. Therefore, a sealing state of the bulb can be maintained surely.Type: GrantFiled: October 29, 2014Date of Patent: May 29, 2018Assignee: HAMAMATSU PHOTONICS K.K.Inventors: Akinori Asai, Naoya Matsumoto

Patent number: 9929770Abstract: An inductor that adjust characteristics of a transmit filter circuit is disposed so that the inductor and at least one of common paths, a matching circuit, a receive filter circuit, and receive paths connected to an output terminal of the transmit filter circuit define a propagation path due to magnetic-field coupling and/or electric-field coupling.
