    • The amplifier includes first and second inverters that form a flip-flop. In this flip-flop, an input of first inverter is connected to an output of the second inverter, and an output of the first inverter is connected to an input of the second inverter. Control terminals of at least one transistors (MN1, MN2) of first and second transistor pairs (MP1, MN1 and MP2, MN2) that constitute first and second inverters, respectively, are connected to inputs of first and second inverters through first and second capacitances (C1, C2), respectively. At resetting, inputs (1, 2) and outputs (OUT, OUTB) of first and second inverters are not mutually cross-connected, wherein a reference signal (VR) is supplied in common to inputs (1, 2) of the first and second inverters. The one transistors (MN1, MN2) are diode-connected. Voltage differences between reference signal (VR) and respective control terminals of the one transistors are stored in the first and second capacitances (C1, C2), respectively. At signal input, diode connections of the one transistors (MN1, MN2) are released. Inputs (1, 2) of the first and second inverters are disconnected from the reference signal. First and second input signals (S1, S2) are supplied to inputs (1, 2), respectively. Then, inputs and outputs of first and second inverters are mutually cross-connected, forming the flip-flop. The amplifier with high-speed and highly reliable operation does not depend on variations in devices therein.

    • A color laser printer 10 compares a pervious printer, which a toner cartridge 40 has been attached to immediately before attachment to the current printer, with the current printer. In the case where the previous printer is different from the current printer, the color laser printer 10 obtains setting information on the previous printer, which is stored in a storage element 50 of the toner cartridge 40, and applies the obtained setting information for the current printer. The various settings in the previous printer are thus turned over to the current printer, when the toner cartridge 40 is detached from the previous printer and is attached to the current printer. This arrangement ensures smooth printing operations without requiring any troublesome settings to use the current printer.
    • 彩色激光打印机10将当前打印机附着之前已经安装了调色剂盒40的透光打印机与当前打印机进行比较。 在前一打印机与当前打印机不同的情况下,彩色激光打印机10获取存储在调色剂盒40的存储元件50中的先前打印机的设置信息,并将获得的当前设置信息 打印机。 因此,当墨粉盒40与先前的打印机分离并且附接到当前的打印机时,上一个打印机中的各种设置因此被翻转到当前的打印机。 这种布置确保平滑的打印操作,而不需要使用当前打印机的任何麻烦的设置。
