Title: Failure detector for load driver
Inventor: HAYASHI KAZUNARI
IPC: H02P29/00
Filed: 1994-02-09
Abstract: PURPOSE:To provide a failure detector for a load driver which can effectively detect a failure state. CONSTITUTION:An OR of a drive signal S1 from a PWM constantcurrent controller 4, a drive signal S2 from a drive command unit 6 and a bar S2 is calculated by an AND circuit 5, a drive signal S3 and a bar S3 are generated, and a load driver 1 is PWM-controlled. A sampling comparator 7 samples a potential VC of a node C to compare it at an interval of 10msec, and increases/decreases a counted value of a counter 8 by a set value in response to a comparison result. When the counter 8 fully counts, the operation of the unit 6 is stopped. As a result, a plurality of failure states are distinguished to be effectively detected. In the case of the failure state, the driver 1 is stopped for its PWM- control and supply of a drive current I to a load Z is cut off, and hence fault of the load Z can be effectively prevented.

Filed: 1997-01-29
Abstract: PROBLEM TO BE SOLVED: To eliminate banding and to improve image quality by restraining the vibration of an optical base and controlling the rotational phase of a light deflector based on vibration detection output. SOLUTION: Light beams projected from semiconductor laser elements 3 and 8 are changed into collimated beams by collimator lenses 4 and 9, and converged on the reflection surfaces of rotary polygon mirrors 6a and 11a by cylindrical lenses 5 and 10, deflected and pass through scanning lenses 7 and 12 so as to irradiate and scan a photoreceptor drum 15 in a spot state.

The vibration is detected by an acceleration pickup 13 and the detection output therefrom is inputted in a rotational phase control part 14.  The control part 14 controls the rotational phase of the deflector 11b based on the detection output so that the peak value of the vibration caused on the optical base 2 may be restrained.

Title: Stereo demodulator circuit
Inventor: TANAKA KANJI
IPC: H04B1/16
Filed: 1979-02-13
Abstract: PURPOSE:To improve the S/N through variation of the high-band cutting amount by giving the control to the differential amplifier via the control signal which is produced in accordance with lowering of the field intensity. CONSTITUTION:Control signals t1 and t2 feature the relation as t2=A-t1. And t1>>t2 is satisfied in case the field intensity is high, and t1 is decreased with lowering of the field intensity. The value becomes approximate to each other between t1 and t2 when the field intensity is small, and thus transistors 24 and 26 start to conduct. Then the high-band cutting main channel signal which is applied to the base of transistor 33 from stereo composite signal input terminal 18 via high-band cutting circuit 32 is begun to be led out to the collector of transistor 26. Thus the cut signal mixed into the output signal is delivered along with the uncut main channel signal which is led out to the collector of transistor 23. And the ratio between these two signals varies smoothly in accordance with the field intensity.

Then, the OA output at the rise time is equal to that at the fall time. The same result can be obtained in case of the application of V x  or V r . As a result, equation (8) containing no voltage (e) can be obtained and V x  can be found by counting times (t 1 ) to (t 4 ) and by executing an arithmetic process according to equation (8).

Abstract: PURPOSE:To monitor well a frequency shift modulation signal, by detecting two frequency components of the frequency shift modulation signal independently of each other and operating the logic between detection results. CONSTITUTION:When a frequency shift modulation (FS) signal 1a has prescribed frequencies fL and fH (fL<fH) and a prescribed level, respective signals 9a, 12a, 10a, 13a, 11a, and 14a of BPFs 9 and 12, amplifiers 10 and 13, and rectifiers 11 and 14 are outputted. BPFs 9 and 12 have frequencies fL and fH of the signal 1a as center frequencies and form a selecting circuit. In this case, either of signals 11a and 14a is outputted momentarily. However, since a gate circuit 15 is operated in accordance with a specific logic, a signal 15a is outputted only during the time when the signal 1a has frequencies fL and fH. Meanwhile, if the signal 1a becomes a stat other than said state because of an abnormality of a transmission line or the like, for example, the signal 1a is broken, the circuit 15 is not opened, and the signal 15a is not outputted.
