Abstract: Provided are a method, a system and a node for implementing APS in an OBRing network. The method comprises: a master node and a slave node separately perform optical power monitoring on respective channels, and aggregate monitoring results to the master node; when determining, according to the monitoring results, that a fault occurs, the master node sends a switching operation instruction to the slave node; and the slave node performs a switching operation and enters a protection working state. With the disclosure, a protection switching mechanism is introduced to the OBRing, which implements the processing on fault and ensures the communication quality of the OBRing.

Abstract: A color wheel driving motor includes a magnet arranged radially outward of a rotor holder. The ring-shaped magnet includes n number of N-pole and n number of S-pole and magnetic pole changeover portions arranged between the poles. The magnetic pole changeover portions are arranged at an angular interval of 360°/2n, the n being a positive integer. On an imaginary plane perpendicular to the center axis, a first straight line passing through the center axis and at least one of the 2n magnetic pole changeover portions makes a specified angle ? with respect to a second straight line extending from the center axis toward the ring-shaped magnet. A first mark is arranged in a region of a surface of the ring-shaped magnet where the second straight line overlaps with the ring-shaped magnet, the specified angle ? being equal to or larger than 0° and equal to or smaller than 360°/2n.

Abstract: A motor includes a rotary and a stationary portion. The rotary portion includes a shaft, a rotor holder, and a rotor magnet. The stationary portion includes a bearing member, a housing, a stator, a circuit board directly or indirectly held in the housing, positioned axially below the rotor holder, and a circuit board support portion provided together with the housing as a monolithic member or directly or indirectly held in the housing, directly or indirectly attached to a device body. The circuit board includes first and second circuit boards positioned respectively axially above and below the circuit board support portion. The first and second circuit boards are electrically connected via a connecting member, and partially overlap. An attachment portion attaching the motor to a device is positioned on an outer peripheral surface of the circuit board support portion.

Abstract: There is provided a method of degrading a heterocyclic aldehyde compound comprising the step of treating the heterocyclic aldehyde compound with Enterobacter sp. microorganisms. There is also provided a method of degrading a carboxylic acid compound comprising the step of treating the carboxylic acid compound with Bacillus sp. microorganisms.

Abstract: An outer-rotor motor includes a stationary portion, a rotating portion, and a bearing mechanism arranged to support the rotating portion such that the rotating portion is rotatable about a central axis extending in a vertical direction with respect to the stationary portion. The stationary portion includes a stator, a mounting plate, and a circuit board. The rotating portion includes a shaft, a rotor holder, and a rotor magnet. The mounting plate includes a projecting portion arranged to project radially. The outer-rotor-motor further includes a guide structure connected with the projecting portion. The guide structure is arranged to extend axially, radially outside the rotor holder. A leadwire is electrically connected to the circuit board, and is guided along the guide structure. Provision of the guide structure, which is arranged to guide the leadwire radially outwardly of the rotor holder, contributes to preventing a contact between the leadwire and the rotor holder.
