The present invention relates to a complementary transistor circuit and, an amplifier using it, and in particular, to a video amplifier for amplifying video signals and a high-definition CRT display device. In amplifying inputted video signals by using a multiplexer, a gain controller and a current mirror amplifier, each element circuit is formed by using complementary transistor circuits. Circuit simplification is thus attained. In addition, higher precision and band broadening has been realized owing to adoption of a current operation. Further, the present invention makes it possible to eliminate direct from the high voltage output completely by providing a low-voltage output circuit for feedback having a similar relationship with respect to the high-voltage video output stage of the video amplifier, thereby performing negative feedback via a sample-and-hold circuit. This also serves to broaden the bandwidth and reduce power dissipation.

摘要:
A method of supplying parts in a system for assembling a printed circuit board by mounting the parts on a substrate at corresponding predetermined positions thereof. One or more kinds of substrates and at least one group of parts, to be mounted on the corresponding substrates, are introduced into the system lot by lot. The introduced parts on one or more previously prepared parts containers are placed so as to correspond to the substrates on which the individual parts are to be mounted, thereby providing one or more sets of the parts, each set corresponding to a respective one of the substrates. The sets of parts are supplied to a parts mounting station of the system.
