Filed: 1989-10-18
Abstract: PURPOSE:To improve the handling of a copying machine by inhibiting the selection of a mosaic monitoring mode in a state where a desired image does not exist and each set value is saved in a storage means in the mosaic monitoring mode. CONSTITUTION:By operating a functional key 78, the mosaic monitoring mode is obtained. A CPU 25 performs different color correction arithmetic operation to image data in an area specified by a jog dial, then the plural images are respectively printed at the different positions of a paper and a timer 40 is started at the same timed. In a state where the desired image is not selected when time is up, mosaic monitoring mode setting data is saved in a mode memory 36 and the mode of a machine automatically return to an initial mode. As long as the saved data exists in the memory 36, the CPU 25 inhibits the new selection of a monitoring mode by referring to the flag of the memory 36. By restoring the saved data when the desired image is selected, the image is printed immediately.

Abstract: PROBLEM TO BE SOLVED: To obtain small base resistance and large maximum oscillation frequency, by constituting a base layer of a hetero junction bipolar transistor of a composition gradient type base layer consisting of In, Ga, As of specific composition ratio, and providing the base layer with impurity concentration gradient. SOLUTION: A base layer of a hetero junction bipolar transistor is constituted of a composition gradient type base layer 2 consisting of In0.x Ga1-x As, and the base layer 2 is provided with impurity concentration gradient. Therefore, it is possible to reduce base resistance by forming a region of high impurity concentration. Since drift electrolysis is generated by using the composition gradient type base layer 2, a base traveling time is reduced. As a result, shielding frequency fT is improved and a maximum oscillation frequency fmax is thereby enlarged, and a base traveling time is also reduced. Therefore, surface recombination in a base layer is reduced and reliability is improved.
