    摘要： A commutator motor includes a stator and a rotor, and the stator includes a stator yoke and a field magnet. The field magnet is fixed onto the inner peripheral surface of the substantially cylindrical stator yoke. The stator yoke is configured by coaxially stacking a plurality of plate-like annular bodies, and the annular bodies are fixedly connected to each other by caulking at a caulking portion disposed on the annular body. In manufacture, the length of the stator yoke in the axial direction can be arbitrarily changed with the thickness of the annular body in the axial direction as a minimum unit. In case of manufacturing various stator yokes that are different in the axial length, the necessity of replacing a manufacturing machine is eliminated, thereby providing a commutator motor having the stator yoke which is low in the manufacturing costs.

    摘要： Provided is a smoke detector having a structure in which, at a time of performing smoke detection, an S/N ratio of a signal of a light receiving element is improved, to thereby accurately detect occurrence of fire. At both end portions of an inside of an optical case (21) having a substantially cylindrical shape, a light emitting element (11) and a stray light portion (22) are arranged. In the stray light portion (22), a light trap (23) is provided. Further, in the vicinity of the light emitting element (11), a condenser lens (24) is provided to allow light L to incident on a curved surface of the light trap (23). At the time of smoke detection, light scattered by smoke particles in a smoke detection portion (25) is received by a light receiving element (12). However, the light incident on the light trap (23) is reflected on the curved surface a plurality of times to be attenuated in each reflection, so the light is not received by the light receiving element (12). Accordingly, the S/N ratio of an output signal S obtained from the light receiving element (12) is improved, thereby making it possible to accurately perform the smoke detection at an early stage.

    摘要： In an analog-to-digital conversion circuit, the gain of an operational amplification circuit in each of first- to third-stage circuits is two. The reference voltage range of a sub-A/D converter in each of the stages of circuits is set to one-half the reference voltage range of a D/A converter, so that the output voltage range of the D/A converter coincides with the output voltage range of the operational amplification circuit. When the voltage range of the analog input signal is VINp-p, the full-scale range of the sub-A/D converter is switched to VINp-p, and the gain of the operational amplification circuit is one. When the voltage range of the analog input signal is VINp-p/2, the full-scale range of the sub-A/D converter is switched to VINp-p/2, and the gain of the operational amplification circuit is two.

    摘要： First and second feeding roller pairs are disposed at positions upstream and downstream of a recording position to record an image onto a recording sheet. Each of the first and second feeding roller pairs includes a capstan roller and a pinch roller, which are located below and above a passage of the recording sheet. The capstan roller and the pinch roller has plural orbital grooves arranged along an axial direction, to relax the strain of the recording sheet with respect to the widthwise direction of the recording sheet. The depth of the orbital grooves of the pinch rollers are set to 0.3 mm, which is shallower than that of the orbital grooves of the capstan rollers. The shallow orbital grooves of the pinch rollers are capable of suppress the curl of the recording sheet effectively.

    摘要： A recording sheet is sequentially fed by the transfer roller pairs, first and second feeding roller pairs and a belt conveyor. The feeding speed V1 of the transfer roller pairs including variation is set to be slower than the feeding speed V2 of the feeding roller pairs. The feeding speed V3 of the belt conveyor including variation is set to be faster than that of the feeding roller pairs. When the recording sheet is transferred to the first feeding roller pair from the transfer roller pairs, one-way clutches in the transfer roller pairs are actuated, to race the transfer roller pairs at the feeding speed V2. Before the recording sheet passes the second feeding roller pair completely, the recording sheet is fed at the speed V2 with the leading end portion thereof being slipped on the belt conveyor.

    摘要： The present invention provides a PHS mobile radio station, which can efficiently attain resynchronization when the wave interference between radio control signals sent from base stations (BS) occurs and no synchronization therebetween cannot be established. The PHS mobile radio station of the present invention has a memory unit for latching the time difference between the transmission times of control signals through logical control channels respectively corresponding to two control frequencies. During this mobile radio station receives control signals in synchronization with the logical control channel (LCCH) corresponding to one of the two control frequencies, if an abnormality in the LCCH synchronization state occurs owing to wave interference, the mobile radio station controls a timing generation unit and a frequency changing unit according to information memorized in the memory unit so that the reception of control signals is synchronized with the logical control channel corresponding to the other control frequency. Thus, this PHS mobile radio station, which can efficiently attain resynchronization.
