摘要:
An axial-air-gap brushless vibration motor has an eccentric rotor R in which an axial-air-gap magnet and an arched weight are provided in a rotor yoke which is rotatably mounted on a shaft fixed to a yoke bracket. A stator base is attached to the yoke bracket which includes a magnetic portion receiving the magnetic field of the magnet and a nonmagnetic portion. One Hall sensor and a drive circuit member for receiving output of the Hall sensor are disposed so that they do not overlap on a radial plane, of the stator base which has single-phase air-core armature coils installed. A cover member is welded to the yoke bracket.

A brushless motor has a drive circuit component mounted on a stator which has plating conducted on a copper foil land to facilitate soldering. Need for a plating line from the outside is eliminated by providing an internal plating connection trace connected to a power feed terminal portion which is subsequently cut by a guide hole for an armature coil. An adhesive resin is applied to the stator where the circuit drive component is installed and the guide hole to adhere simultaneously to the stator to a bracket and the armature coil to the stator and bracket.

The present invention provides a carrier for replenishment including an associated particle in which single particles each having a core material and a resin layer covering the core material, are bound via the resin layer, the carrier being used in a developer for replenishment of a trickle development system, and the system including performing development while the developer for replenishment is replenished, upon development of a latent image on a latent image holding member using a development unit.
摘要:
In a radio communication system that simultaneously uses plural radio channels (STA1), a radio communication apparatus (11-15; 20-25) can quickly secure plural radio channels simultaneously used for radio communication while preventing collision with a radio signal transmitted by another radio communication apparatus so away from the radio communication apparatus that the radio communication apparatus cannot detect radio waves. A radio communication apparatus STA1 according to the present invention includes a receiving unit 10 which receives, when a first signal is transmitted via each of the plural radio channels (21-25), the first signal though at least one or more radio channels among the plural radio channels (11-15), and performs carrier sense for each of the plural radio channels used for the transmission of the first signal, a selecting unit 40 which selects a radio channel used for radio communication out of radio channels set in a standby state, and transmitting unit 20 which transmits a response signal for the first signal via the selected radio channel.

摘要:
A wireless communication apparatus is disclosed. A transmitting device transmits a first aggregation frame in which first transmission data frames are aggregated. A measuring device measures a number value of retransmission of each of the first transmission data frames. A storage stores a limiting value of the number value of retransmission. A determination device determines whether the number value of retransmission of each of the first transmission data frames exceeds the limiting value. A transmission buffer buffers the first transmission data frames for which it is determined that the number value of retransmission does not exceed the limiting value, and discards the first transmission data frames for which it is determined that the number value of retransmission exceeds the limiting value, of the first transmission data frames. A retransmitting device retransmits the first aggregation frame in which the first transmission data frames buffered in the transmission buffer are aggregated.
摘要:
A wireless communication apparatus for performing wireless communication using a first channel having a first frequency bandwidth, and a second channel formed of both the first channel and a second communication channel, the second communication channel having a frequency bandwidth equal to the first frequency bandwidth. A first generation of a first declaration frame for declaring occupation of the first channel for a specified period, and a second generation of a second declaration frame for declaring occupation of the second communication channel for a specified period after the first declaration frame are generated and transmitted. Transmission timings are set so that the first and second declaration frames are transmitted at the highest priority of all the other frames.
