Title: Signal meter driving circuit of receiver
Inventor: NUMATA TATSUO
IPC: H04B1/16
Filed: 1982-02-02
Abstract: PURPOSE:To prevent an inconvenient phenomenon in which a signal meter has no deflection, by drawing a driving signal which drives the meter out of a common connecting electrode of a pair of active elements after applying the bias voltage to said active elements. CONSTITUTION:When the resistance value of each resistance is set at a proper level, the voltage which is higher by the forward direction voltage of a diode D2 than the bias voltage supplied from a bias voltage supply circuit 18 is applied to bases of AM wave detecting transistors TRQ28-Q33 in a non-signal mode. Thus the TRQ28-Q33 are all turned off. The level of an input signal increases during the input of signals, and a full-wave rectifying current proportional approximately to the level of input signal is delivered from a common collector of the TRQ28-Q33 until each of differential amplifiers 8-9 functions as a limiter.  As a result, the both-terminal voltage of a resistance R26 of an output circuit 19 and the driving voltage delivered from the circuit 19 are varied in response to the input level of an antenna. Then a signal meter is driven in response to the input level of the antenna.

Title: Flow measuring instrument
Inventor: KAWAKAMI TAKASHI
IPC: G01P13/00
Filed: 1987-01-27
Abstract: PURPOSE:To enable a flow to be measured regardless of an environment wherein a fluid is situated by conducting subtraction on the image signals of two temporally different images which are inputted from an image sensing device and measuring the direction and the velocity of the flow of the fluid. CONSTITUTION:A television camera 1 for photographing the field of flow wherein a tracer particle is mixed acquires an image and resultant image signals A are stored in a frame memory 4. Then, the image is inputted again and resultant image signals B are stored in the frame memory 4. Normally, those image signals A and B are continuously inputted at the photographing time intervals of the television camera 1. Then, subtraction (A-B) is performed on the stored image signals A and B. Thus, since there is no change in density in the background portion of the image even if an article is present therein, resultant subtracted values are equal to zero. The starting and terminating points of the movement of the tracer particle are obtained from the image after the subtraction to determine the direction of the flow. Then, by measuring a distance between the starting and terminating points and dividing the distance by an image input time interval, the velocity of the tracer particle, namely, the moving velocity of fluid is calculated and the obtained direction and velocity are displayed as vectors.
