The resonance unit includes: a first waveguide; a first reflector to input the reflected light to the first waveguide; a second waveguide; a second reflector connected to the second waveguide; and a ring resonator between the first waveguide and the second waveguide. The light from the first reflector is blocked from the ring resonator and partially transmitted to a first end of the first waveguide opposite to a second end connected to the light emitter and the first reflector. The optical negative feedback unit includes: a third waveguide to which the light transmitted to the first end of the first waveguide is inputted; and a third reflector connected to the third waveguide. The light from the third reflector is inputted to the first waveguide via the third waveguide.

Abstract: A welding burn remover includes: a mover including a movable body to which a support of an electrolytic end effector is attached and at least one actuator that moves the movable body; and processing circuitry configured to control the actuator. The processing circuitry is configured to execute an electrolytic treatment in which the processing circuitry controls the actuator to slide an electrode on a welding burn portion of a welded workpiece through a short-circuit prevention cover while controlling a pump to supply an electrolytic solution to a boundary by an electrolytic solution feeder. The support of the electrolytic end effector includes: a base attached to the movable body of the mover; and a coupler connecting the electrode to the base such that the electrode is angularly displaceable relative to the base.

Abstract: A laser apparatus includes: a light source configured to generate laser light; and an optical negative feedback unit configured to narrow a spectral line of the laser light using optical negative feedback. A modulation signal is input to the light source to modulate a frequency of the laser light. A modulation amount in the frequency of the laser light is detected. A modulation sensitivity is calculated from (i) the modulation amount and (ii) an intensity of the modulation signal.

Abstract: Conventional satellite communication systems operated under DAMA system have such disadvantages that assignment of communication lines becomes time-consuming in case of transmitting small quantity of data many times and that data transmission is impossible in case of no available communication line, because the line assignment is performed by DAMA system for each individual demand for line assignment regardless of data quantity to be transmitted. The invention provides a satellite communication system in which the time required for assigning and securing a communication line can be shortened and communication lines can be utilized more efficiently, because of using single or plural common signal channel lines instead of using ordinary communication lines in case that data quantity is below a certain level.

Abstract: The satellite communications system according to the present invention transmits data from the VSAT to the HUB through a fixedly predetermined first forward satellite channel. The HUB, on receiving a request for allocation of a second forward satellite channel having a greater frequency band than that of the first forward satellite channel, allocates the second forward satellite channel to the VSAT concerned on condition that the second forward satellite channel being unoccupied. According to this architecture, mass data can be transmitted effectively using the second forward satellite channel having a larger capacity than that of the first forward satellite channel.
