Abstract: PURPOSE: To obtain a low-noise frequency synthesizer, having low phase noise and a spurious level by adjusting a gain of a phase detection means for compensating a change in a division number and providing a digital control means that selects a 1st or 2nd division number. CONSTITUTION: A 1st divider 13 receives an input signal f1 and outputs a reference frequency signal fR which is equal to an input signal divided by a 1st dividing number N. A voltage-controlled oscillator 18 generates an output fO of the frequency synthesizer. A divider 15 receives the output fO and outputs a reference frequency signal fC equal to an output signal, divided by a 2nd dividing number M. A phase/frequency detector 14 compares the reference frequencies fR, fC to produce a phase error output signal, and the gain is controlled by a gain control output voltage signal GC of a D/A converter 12. A digital controller 20 adjusts the gain of the detector 14 to compensate a change in the division number and selects a 1st or 2nd division number N, M.  Thus, the divider which uses a half of an integer division number and the low-noise frequency synthesizer which uses analog gain compensation are obtained.

Title: Flame detector
Inventor: KAWAKAMI YUICHI
IPC: G01J1/42
Filed: 1985-04-27
Abstract: PURPOSE:To make it possible to accurately detect the generation of a fire, by comparing the integration value of the output of a first light receiving element to a flame with the integration value of the part shifted in the phase difference of the output of the first light receiving element and that of a second light emitting element to visible light. CONSTITUTION:When only obstruction light such as sunrays is present but a flame is absent, the output of a first light emitting element is also slightly present and the slight phase shift (c) from the output of a second light receiving element 4 is present in the output of said first light receiving element 2. Therefore, both integration values (d), (e) of first and second integrating means 14, 16 also increase but, because the presence of the flame is judged on the basis of the ratio of both integration values, obstruction light is cleary discriminated. When the flame and the obstruction light are present in a mixed state, the phase shift (c) of the outputs of both light receiving elements 2, 4 is large as compared with such a case that only obstruction light is present and, therefore, the integration value (e) of the second integrating means 16 becomes relatively large as compared with the integration value (d) of the first integrating means 14 and the generation of the flame is accurately detected. Further, when only the flame is present, there is almost no output of the first light receiving element and, therefore, the ratio of both integration values (d), (e) is almost 1 and the flame is detected.

Title: Dc motor drive circuit
Inventor: YAGUCHI OSAMU
IPC: H02P7/29
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To perform speed control of a DC motor surely through a simple structure by varying the duty cycle of a cut-off pulse for turning a drive transistor off instantaneously and periodically. SOLUTION: Output signal P2 from a pulse forming circuit 11 corresponds to a cut-off pulse outputted from an oscillator. A voltage comparator 7 compares the output voltage VN from a saw-tooth wave forming circuit 12 with a set voltage V2 and sets a high level H interval of the output signal P2 N from the pulse forming circuit 11. Consequently, locking torque of a DC motor 1 can be controlled over a wide range. Subsequently, a variable resistor VR2 in the saw-tooth wave forming circuit 12 varies the rising rate and lowering rate of output voltage VN from the saw-tooth wave forming circuit 12 simultaneously in the opposite directions thus varying the duty cycle of the output signal P2 from the pulse forming circuit 11. Speed control of the DC motor 1 is performed by varying the duty cycle of output signal P2 from the pulse forming circuit 11.
