Title: Transmission power controller
Inventor: YAMAMOTO OSAMU
IPC: H03G3/30
Filed: 1987-11-30
Abstract: PURPOSE:To compensate properly the gain fluctuation by fixing the gain of an ALC loop by a just preceding value when an input level reaches a reference value or below. CONSTITUTION:The ALC circuit is operated and the gain is controlled to a prescribed value by forming a negative feedback loop so that the output of an output level detector DET 2 is coincident with the value detected by an input level detector DET 1 used as a reference value. If the input level of the input level detector DET 1 is lowered than the prescribed value by a hold circuit HLD connected to the error amplifier A, it is detected by a comparator COMP to drive the hold circuit HLD thereby holding the just preceding input level. Thus, the compensation effective to the loss fluctuation of the cable connecting indoor and outdoor devices due to temperature as well as the gain fluctuation of the indoor and outdoor devices due to temperature is attained.

Abstract: PURPOSE:To transmit the torque in good performance, facilitate maintenance and inspection, increase the reduction ratio, and prolong the lifetime by putting a pressure contact roller in pressure contact with a rotor, and putting the drive roller in pressure contact with rotor through two follower wheels. CONSTITUTION:A pressure contact roller housing 36 is pressed by a spring 40 toward a rotor 3, and thereby pressure contact rollers 6a, 6b are put in pressure contact with the rotor 3 with a certain pressure, and the reactive force therefrom puts the roller housing 36 in eccentricity in the direction of separating from the rotor 3. As a result, a drive roller housing 21 constructed in a single piece with the roller housing 36 is put in eccentricity in the direction of approaching the rotor 3, and a drive roller 5 having rigidity is put in pressure contact with the major dia. portions 7c, 7f of two follower wheels 7a, 7b having rigidity, while minor dia. portions 7e, 7h are put in pressure contact with the rotor 3 having rigidity. When therein the drive roller 5 is rotated by the drive motive, the driving power of the drive motive is transmitted to the rotor 3 while decelerated through frictional engagement one after another. Thus the rotor 3 is driven for rotating.

Title: Pll synchronization detecting circuit
Inventor: NAKAGAWARA TOMOMASA
IPC: H04N5/455
Filed: 1986-12-18
Abstract: PURPOSE:To suppress influence due to disturbance such as noise, etc., and to obtain a stable detecting characteristic at the time of inputting a weak electric field signal or an overmodulation signal, by increasing a difference between a mean potential and a reference potential at the time of locking and unlocking a loop circuit. CONSTITUTION:A video intermediate frequency signal is supplied to a first input of each of a video detector 1 and a phase detector 2, and the detector 2 constitutes a PLL circuit with a loop filter 3, a voltage controlled oscillator 4 and a phase shifter 5. And when a PLL signal is unlocked, the detector 1 outputs a video signal OUT. The signal OUT, the lower side of which being clipped by a clipping circuit 10, becomes a clip waveform (a), and its mean potential VAV is set higher than the mean potential of the signal OUT. Therefore, a potential difference between the mean potential of the signal OUT outputted from the detector 1 at the time of locking the PLL signal and the clip waveform is expanded, thereby, a loop filter switching characteristic can be stabilized.

Title: Infrared detector
Inventor: OKUDA HIDENORI
IPC: G01V8/10
Filed: 1996-11-12
Abstract: PROBLEM TO BE SOLVED: To prolong the service life and to enhance the fixing performance while saving energy by driving a chopper and a scanning mechanism only when the temperature variation in an objective space is detected. SOLUTION: A chopper 3 is normally brought into open state through a control section 5 and a scanning mechanism 4 is not driven. When the temperature is varied due to passage of an intruder, for example, variation in the infrared energy passing through an infrared condenser lens 2 and arriving at a sensor 1 is detected and then the chopper 3 and the scanning mechanism 4 are driven. Furthermore, the control section 5 obtains a two-dimensional temperature distribution by converting the output from the sensor 1 into a temperature and checks presence of an intruder or a high temperature body. The operation is continued until the intruder or the high temperature body disappears. Since the detector is operated only when it is required, service life can be prolonged while saving energy and since only one sensor is required, the detector can be fixed easily and inexpensively.

Namely, since a logical action is executed by switching the constant current to flow in the constant current source and by switching both terminals of the Josephson junction to the voltage condition and interrupting condition, it is sufficient that a power source voltage supplies a constant voltage, a complex circuit constitution generated from the hysteresis characteristic of the Josephson junction is not necessary to be adopted, and the high-speed and simple Josephson junction integrated circuit can be realized.

Abstract: PURPOSE:To lessen a semiconductor integrated circuit in power consumption by a method wherein a bipolar transistor is decreased in steady-state current in a time domain wherein an output signal is kept unchanged at a low level in the output circuit of a BiCMOS gate array.
