摘要： A projection display device includes: a projection portion which enlarges and projects the light modulated by a imager portion; a control circuit; and a main body cabinet. The projection portion is formed by a projection lens portion into which the light from the imager portion is entered and a mirror portion which reflects the light having passed through the projection lens portion and lets the light travel toward a projection plane. The mirror portion is disposed so as to be shifted from an optical axis of the projection lens portion in a direction opposite to a direction in which the incident light from the projection lens portion is turned back. The control circuit portion is disposed in a space which is produced between the projection lens portion and the main body cabinet by a position gap between the projection lens portion and the mirror portion.

摘要： Disclosed is a VTR of the helical scan type having a plurality of rotary magnetic heads. This VTR can select one of a first and a second signal recording forms which are different from each other, and record signals on a magnetic tape. In the first recording form, a frequency-modulated video signal including a luminance signal and a color signal and a frequency-modulated sound signal are recorded on the same track so as to be superimposed one on the other. In the second signal recording form, a frequency-modulated luminance signal and a frequency-modulated color signal are recorded separately on tracks adjacent to each other. This VTR has compatibility with respect to the recording/reproducing of two different signals.

摘要： Disclosed is a circuit for emphasizing a video signal in the vertical direction of a television picture for minimizing noise appearing during reproduction. In the circuit, a signal obtained by delaying an input video signal by one horizontal scanning period is positively fed back through a feedback circuit to the input of the input video signal. An amplitude difference signal between the video signal after being fed back through a positive feedback loop and the delayed video signal is produced and added to the input video signal to provide an output video signal.
