  • Patent number: 10061026
    Abstract: A photoelectric sensor includes the following components. A disturbance detection unit detects a disturbance by comparing a light reception result obtained by a light receiver with a first threshold and with a second threshold for a predetermined period in a state where no light is transmitted by a light transmitter. The second threshold takes a value of a sign opposite to that of the first threshold relative to a no-signal state. A waiting unit waits for the light reception result obtained by the light receiver to become within a range from the first threshold to the second threshold upon detection of a disturbance. A disturbance type determination unit causes detection of a disturbance to be performed again after the waiting. A light transmission instruction unit instructs the light transmitter to transmit light when no disturbance is detected for a predetermined period.

  • Patent number: 9303333
    Abstract: A bismuth-substituted rare-earth iron garnet crystal film (RIG) which has an insertion loss of less than 0.6 dB and which can be produced in a high yield, as well as an optical isolator, which is grown by liquid phase epitaxy on a non-magnetic garnet substrate represented by a chemical formula of Gd3(ScGa)5O12, wherein the RIG is represented by a chemical formula of Nd3-x-yGdxBiyFe5O12, and x and y satisfy 0.89?x?1.43 and 0.85?y?1.19. In contrast to conventional RIGs, the RIG represented by the chemical formula of Nd3-x-yGdxBiyFe5O12 of the present invention has an insertion loss of less than 0.6 dB and makes it possible to reduce the amount of heat generated because of absorption of light at wavelengths of about 1 ?m. Hence, the RIG has such a remarkable effect that the RIG can be used as a Faraday rotator used for an optical isolator in a high-power laser device for processing.

  • Patent number: 7282839
    Abstract: Provided is a multilayer piezoelectric device high in reliability and easy in formation of a unit when incorporated into various devices. In a multilayer piezoelectric device, each second external electrode is integrally formed including a main body part electrically and physically connected to a first external electrode, and an extending part having an upper end projecting with respect to an upper face of laminate in a stack direction. This permits the extending part of the second external electrode to be used as a terminal, and, because the second external electrode is integrally formed, the second external electrode can be prevented from breaking. Therefore, it results in improving the reliability of piezoelectric device. Furthermore, between second external electrodes facing each other, a distance between extending parts is larger than a distance between main body parts, and thus it becomes easy to form a unit of the piezoelectric device when incorporated in various devices; e.g.
