Title: Optical transmitter
Inventor: RIJCK ALEXANDER CHRISTIAAN DE
IPC: H04B10/43
Filed: 1992-04-03
Abstract: PURPOSE: To provide an optical transmitter having a control loop for fixing a bias current having a light quantity radiated by a laser diode, cascade circuit for the laser diode and a variable gain amplifier included in the negative feedback path of the photodiode and the control loop. CONSTITUTION: The laser diode can perform amplitude modulation by supplying a modulating signal to an adder 4. To avoid that the control loop cancels the mean value of the modulating signal, an cancel signal having an amplitude such that the output signal of a control amplifier 3 is independent from the modulating signal is transmitted to the input of the control amplifier 3. To induce the cancel signal from the modulating signal by a specified method, the transmission rate of the negative feedback path is fixed by the transmission of an auxiliary signal by negative feedback, is measured by a comparing circuit 12, and the gain of the amplifier 8 is controlled by adopting this transmission rate based on this measurement result.

Patent JP-S585616-A (JP)
Title: Flowmeter
Inventor: ISHII YASUSHI
IPC: G01F1/78
Filed: 1982-06-29
Abstract: PURPOSE:To make it possible to measure a large flow rate by a compact device, by providing a branched flow path from a main pipe wherein fluid to be measured flows, and obtaining the flow rate based on the increment of the pressure increase that is obtained by imparting the increment of the increase in the flow rate to the branched flow. CONSTITUTION:The most part of the fluid to be measured flows out through an orifice R3 of the main pipe 2. A part of the fluid is separated at a point A, flows through orifices R1 and R2, and joins the main stream at a point C. A piston 5 is moved in a sine wave state by a driving device 6, and the variation in the flow rate is obtained. The pressure variation corresponding to the increased increment DELTAQ of the low rate caused in this way is detected by a pressure difference transducer 7. Its output is inputted to a tuning amplifier 8, and the output is detected by an AC voltmeter 9. Thus the mass flow rate is obtained. The measurement is performed on the small branched flow and the large flow rate in the main pipe, which has the proportional relationship with said small flow is obtained. Therefore the large flow rate can be measured by a compact device.

Title: Detection circuit for moving of television signal
Inventor: HIRANO YASUHIRO
IPC: H04N19/50
Filed: 1986-05-16
Abstract: PURPOSE:To detect a moving information corresponding to the speed of the moving by measuring the length of a period during which the absolute value of an in-frame differential signal exceeds a specific value. CONSTITUTION:A one farme delay signal from a one frame delay circuit and a current signal are inputted to a differential circuit 2 to generate an in-frame differential signal. This differential signal is converted by a threshold circuit 3 to a binary signal in a manner that, if its absolute value exceeds TH, it is made '1', but made '0' in other cases. A speed detection circuit 5 generates a speed information (k) corresponding to the length of the run of the '1'. The extent of the binary signals in '1' corresponds to the amount of moving within one frame. Therefore, by means of the length of the extent of the '1', i.e. by measuring the length of the run of the '1', the amount of moving per frame, in other word the speed of the moving, can be detected.
