    摘要： A full adder that operates rapidly with low power supply voltage and minimal power consumption, and further, that occupies a small area on a semiconductor element. A sum signal calculation circuit 10 of full adder 1 performs addition of input signals A and B and carry in signal C and outputs sum signal S.sub.out. Carry signal calculation circuit 16 outputs carry out signal C.sub.out corresponding to the combination of the logic values of input signals A and B and carry in signal C. Sum signal calculation circuit (10) is composed of addition signal generation circuit (12) and sum signal generation circuit (14). Addition signal generation circuit 12 performs XOR logic operations on input signals A and B. Sum signal generation circuit 14 outputs the results of full addition operations on inputs signals A and B and carry in signal C as sum signal S.sub.out, based on the results of XOR logic operations by addition signal generation circuit (12) and carry in signal C.

    摘要： The operation modes of a plurality of modems in a communication system are matched with each other for connection of digital terminals to an analog telephone line on both the calling and answering sides of the analog telephone line. For example, operation modes of modems on both sides of the analog telephone line can automatically be matched with each other by transferring a mode instructing signal with DTMF, using multi-frequency DTMF symbols for a select signal employed in the telephone line, between digital terminals connected to both ends of the telephone line. More specifically, even in the case of the calling and answering sides being in different initial operation modes, the different operation modes are matched by setting a desired operation mode on the calling side and generating an off-hook signal on the answering side in response to a calling signal, followed by (1) transmitting an operation mode instructing signal in the form of a code with DTMF from the calling side to the answering side, setting the instructed operation mode on the answering side and returning if it can be set on that side, and then returning an answer tone to the calling side for completing the mode matching; or when the operation mode instructed from the calling side cannot be set on the answering side, transmitting an operable mode in the form of a code with DTMF from the answering side to the calling side, and transmitting again the code corresponding to that mode from the calling side to the answering side if that mode can be set on the calling side, thereby matching operation modes of both the calling and answering sides, or (2) transmitting an operation mode instructing signal in the form of a code with DTMF from the answering side to the calling side, and then carrying out a procedure similar to above (1).

    摘要： This invention is a solid-state image pickup device that solves the problem of limited dynamic range in the high luminance region in an image sensor having white pixels. White pixels or yellow pixels and at least red pixels, green pixels or blue pixels are arranged in array form on the light receiving surface of a semiconductor substrate. White pixels or yellow pixels have an additional capacitance CS connected to the photodiode via the floating diffusion, a capacitance coupling transistor S that can couple or separate the floating diffusion and the additional capacitance. The proportion of white or yellow pixels to the total number of pixels is higher in a central portion of the light receiving surface than a peripheral portion. The white or yellow pixel may share a floating diffusion with a red, green or blue pixel.

    摘要： A drive circuit in which the rise and fall characteristics with multiple voltages are made the same, while maintaining a high breakdown voltage. Drive circuit 70, which supplies power supply voltages VH and VL and voltage VM intermediate between them to output pad 32, is composed of p-channel MOS transistor P5 and n-channel MOS transistors N5, N6 and N7. When the output voltage changes from VH to VM, both transistors N6 and N7 conduct, and when the output voltage changes from VL to VM, only transistor N6 conducts. The transistors that supply intermediate voltage VM are constructed of transistors of the same conductivity type, so that the rise and fall characteristics to VM can be made the same while the breakdown voltage of the transistors in the circuit that supplies this intermediate voltage VM is kept high.

    摘要： A method and apparatus for matching operation modes of modems for connection of terminals to a telephone line, i.e., matching operation forms determined by a communication speed, a coding format, a synchronizing format, etc., on both the calling and answering sides of the telephone line. When the answering side detects an extension specifying signal sent from the calling side, an operation mode of a modem corresponding to the extension specifying signal is used to select the specified operation mode from among a plurality of operation modes for modem circuits equipped on the answering side, for matching the operation mode of the answering side modem with that on the calling side. The answering side modem has a function of detecting a push-button dial signal serving as the extension specifying signal, and a function of providing the plurality of operation modes for the modem and optionally changing the operation mode upon an instruction from an answering side terminal. The answering side terminal determines the correlation between the extension specifying signal from the calling side and the operation mode of the calling side modem. A calling terminal sets a call using a telephone number which contains the extension specifying signal of the dial-in service corresponding to the operation mode of the calling side modem, and the answering side terminal converts the extension specifying signal to the corresponding operation mode.
