Title: Switching type dc power amplifier
Inventor: YAMAZAKI MIKIO
IPC: H03F3/217
Filed: 1988-09-12
Abstract: PURPOSE:To satisfy a high stability, a high gain and a board frequency band simultaneously by connecting a preamplifier between an input signal and an input terminal of an error amplifier to which the input signal is to be applied. CONSTITUTION:An open loop gain A5' to decrease sufficiently the effect of a voltage fluctuation of a DC power supply 1 on an output voltage is set. Then a gain of a smoothing filter below the cut-off frequency 10 is set so as to obtain an open loop gain enabling the phase lead compensation is set. Finally the phase lead compensation is applied at a phase lead compensation frequency 15 slightly higher than the cut-off frequency 10 of the smoothing filter is applied. In order to set the DC gain A5' higher, the gain is higher at a low frequency region close to a DC in the closed loop characteristic A6 of the control loop and the linearity as the amplifier is deteriorated. Thus, the gain of the said frequency region is set lower in the transfer characteristic A7 of the preamplifier 14 is set lower. As a result, the overall input/output transfer characteristic A8 of the DC power amplifier is made flat at a required frequency band. Moreover, since the DC gain A5' of the open loop is high, the fluctuation in the output voltage due to the voltage fluctuation of the DC power supply 1 is decreased.

Title: Movie with liquid crystal finder
Inventor: WAKABAYASHI MANABU
IPC: H04N5/66
Filed: 1989-09-06
Abstract: PURPOSE:To attain a proper use of the movie at a bright outdoor state by providing a liquid crystal panel, a transparent protection plate and a continuous layer packed between the liquid crystal panel and the protection plate to a liquid crystal finder. CONSTITUTION:A transparent continuous layer 3 whose diffraction rate is nearly 1.5 is packed between a protection plate 2 arranged to a liquid crystal display face and a liquid crystal panel 27 and surface reflection prevention films 1, 36 are formed on the surface of the protection plate 2 in contact with air. Since the surface reflection of light is generated at the border face between transparent substances when the diffraction rates of the transparent substances differ from each other, the reflection in the border face is prevented by arranging the diffraction rates of the transparent substances in contact with each other. The diffraction rate of the protection plate 2 and the liquid crystal panel is nearly 1.5 and the diffraction rate of the continuous layer 3 is nearly 1.5. Thus, the surface reflection of the rear face of the protection plate and the surface of the liquid crystal panel is suppressed and the use at bright outdoor is made suitable.
