Abstract: When a temperature of cooling steam being measured by a temperature-measuring device 13 in one combustor 2-x among combustors 2-1 through 2-8 is confirmed to be higher than a temperature of a predetermined time before by a predetermined value and temperatures of cooling steams being measured by temperature-measuring devices 13 in combustors 2-y and 2-z being adjacent to the combustor 2-x on both sides are confirmed to be lower than a temperature of a predetermined time before by a predetermined value, an occurrence of a flashback is detected in the combustor 2-x.

Abstract: 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.

Abstract: A vibration motor and speaker device includes a speaker excitation magnet around a flat brushless vibration motor which acts as a speaker magnetic pole. the vibration motor has a case constituting motor housing that comprises a magnetic body on a lateral periphery, a ceiling portion made of a nonmagnetic body, and a detent torque generation part disposed on a bracket and receiving the magnetic field of a rotor magnet. The detent torque generation part is separated from the magnetic body portion of the motor housing thus reducing effects of the magnetic field of the speaker excitation magnet.

Abstract: 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.

A multilayer printed circuit board includes a plurality of substrates, each having a conductive pattern on at least one face thereof. Any adjacent two of the substrates are separated by an insulating layer, and the conductive pattern of a first substrate of the two substrates faces the conductive pattern of a second substrate of the two substrate.
