Abstract: PURPOSE:To prove a stable excitation control irrespective of a rotating speed change of a synchronous machine by providing a speed detector for detecting a variation in the speed of the machine, and providing means for so varying a control function of an automatic voltage regulator in response to an output of the detector as to stabilize an excitation control system. CONSTITUTION:A difference between a voltage detection signal D of a voltage detector 6 which inputs a terminal voltage of a synchronous machine 1 through a transformer 7 for an instrument and a voltage set signal R by a voltage setter 9 is obtained by a comparator 8, and its error signal E is input to a voltage controller 12. A rotating speed of the machine 1 is detected by a speed detector 14 based on a pulse signal SS generated from a speed detection generator 13, and input to the controller 12. The controller 12 amplifies the signal E, phase-improves to stabilize a control system to output a voltage control signal C, and continuously varies an amplifying function in response to a speed signal N. A thyristor rectifier 4 is controlled by the signal C through a phase controller 11.

Filed: 1979-08-15
Abstract: PURPOSE: To enable focusing to be performed with a simple circuit by Fourier-transforming the subject image with a Fourier transformation lens and using this information as the focus control information of the taking lens.  
     CONSTITUTION: The image of a subject 1 imaged on a screen 4 by a taking lens 2 is trasformed by using a Fourier trasformation lens 6 and the image thereof is  formed on a Fourier information imaging plane 7. This information is transformed  in a photoelectric transforming part 8 and the luminances PA, PB of the low-frequency section and high-frequency section of space frequencies are measured. Next, the operation of PB/PA is performed by an arithmetic circuit 9, then the point where the results of the operation become maximum is the point where the focus has matched. Hence, the displaying of the moving direction of the taking lens or its automatic focusing may be performed. In this way, the focusing may be performed with the simple circuit.

Title: Moving picture decoder
Inventor: YAMAZAKI MASATO
IPC: H04N19/91
Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To allow a television receiver adopting an interlace scanning system to display a noninterlace scanning image signal of 60 frames per second by decoding a stream resulting from applying MPEG coding to the image signal with an inexpensive decoder. SOLUTION: A stream analysis section 2 of this moving picture decoder sequentially detects I, B, P picture codes from a coding stream and gives them to a frame abort section 4. The frame abort section 4 alternately aborts any of two B pictures between I, P pictures and between P, P pictures and gives a remaining code to a video decoding section 6. Thus, the video decoding section 6 decodes a frame code with number of frames less than 60 frames per second and gives the result to a display control section 8. The display control section 8 interlaces prescribed P pictures to read the remaining decoded frames by respective fields and a display device displays them interlaced.
