IPC: H04B1/709
Filed: 1993-02-24
Abstract: PURPOSE:To reduce the circuit scale, to quicken the circuit operation and to reduce power consumption by using a spread code signal so as to control the noninversion and inversion of a received signal at a base band, integrating the signal for a predetermined period and squaring the integrated value. CONSTITUTION:An amplifier 11 noninverts/inverts an inputted base band signal A to output a signal C when the polarity of a spread signal B is +/- and an A/D converter 12 applies A/D-conversion to the signal C in a timing D. When the converted signal is added for a predetermined period by an integration device 13, the sum output is a signal E or J depending whether correlation is taken between the signals A, B and increased or not increased. Thus, the correlation with a spread signal is obtained by using a square device 14 to square the output of the integration device 13 and when the correlation is taken, the output of the integration device 13 is used for decoding data. Thus, the circuit scale is reduced, the circuit operation is quickened and the power consumption is decreased.

IPC: H02K1/24
Filed: 1978-03-27
Abstract: PURPOSE: To provide the subject damper windings which are arranged and installed asymmetrically with respect to the center of magnetic pole, thereby to prevent the increase of a field current in an on-load drive state and to reduce thermal and mechanical burdens of the damper windings due to leakage flux.  
     CONSTITUTION: Damper winding conductors 3 are arranged asymmetrically with respect to the center O of a magnetic pole 1 so that the conductors 3 are selected only in other low magnetic flux distribution zone B" excepting a high magnetic flux distribution zone B' corresponding to an on-load gap magnetic flux distribution B. According to this arrangement, even when the on-load gap magnetic flux distribution is deflected as indicated by line B by an armature reaction, the core section in the high magnetic flux distribution zone in the top region of the magnetic pole 1 is sufficiently secured, and henced the magnetic flux density distribution of the core magnetic path is substantially equilibrated in the full region, and the magnetic saturation is evaded. Accordingly, the increase in the field current generated by the damper winding arrangement and the influence on the leakage flux with respect to the damper windings can be reduced.

Title: Automatic frequency control circuit
Inventor: ISHIKAWA TOMOYOSHI
IPC: H03L7/06
Filed: 1990-02-16
Abstract: PURPOSE:To output the output signal of a prescribed level independently of the depth of modulation in an input signal by using an attenuator controlled with a voltage obtained from a difference signal between a signal from a 1st band pass filter and a 2nd band pass filter to adjust the level of a signal outputted from a mixer. CONSTITUTION:The band width of a 2nd band pass filter 10 is made wider than a required band width when the modulation of an input signal is maximized. When the signal is not modulated or the modulation is shallow, since a band pass filter 4 passes all signal components, the output voltage of the detector 7 is constant. Similarly, the detection voltage of a detector 11 also constant. When the modulation is made deeper, the detection voltage of the detector 7 is dropped and the difference of the detection voltage of the detector 11 is increased and a logic circuit 12 receiving both the detection voltages outputs a correction value in response to the difference of the detection voltages. Thus, the AGC operation of a prescribed output level is implemented independently of the depth of modulation.
