摘要： In a correlation arithmetic system adapted to detect a relative difference between two functions, an operation is simplified. This makes it possible to perform the operation with a small scale of hardware and also with great accuracy. There is adopted an operation g*h instead of the “product” in the correlation arithmetic operation. There is disclosed an arithmetic unit in which two numeral values a and b are inputted, and the two numerical values a and b are subjected to a predetermined operation process, so that a numerical value c representative of an operation result is derived. The arithmetic unit has an absolute value operation unit for evaluating an absolute value |c| of the numerical value c, and a sign operation unit for evaluating a sign “sing (c)” of the numerical value c.

摘要： A single-photon generating device is configured to have a solid substrate including abase portion, and a pillar portion which is formed on the surface side of the base portion with a localized level existent in the vicinity of the tip of the base portion. The above pillar portion is formed to have a larger cross section on the base portion side than the cross section on the tip side, so that the light generated from the localized level is reflected on the surface, propagated inside the pillar portion, and output from the back face side of the base portion.

摘要： A timing recovery unit detects a phase offset and a frequency offset from a head area of reproduction data and initially corrects them. The timing recovery unit stores data in which a head reproduction signal has been made to be discrete by a fixed clock into a buffer. A phase offset detector detects the phase offset from the data head area in parallel with the operation for writing the data into the buffer. At the same time, a frequency offset detector detects the frequency offset from the data head area in parallel with the operation for writing the data into the buffer. A correction value of the detected phase offset and a correction value of the detected frequency offset are initially set into a digital PLL. While the data is read out from the buffer, a frequency lead-in and a phase lead-in are executed in the head area.

摘要： A logic circuit including a transistor having a control electrode connected to three input terminals at which are received three respective input signals, each having, selectively, either a high or a low voltage level, and first and second electrodes, one thereof connected to a first power supply potential and the other thereof connected through a diode having N-type negative differential resistance to a second, lower power supply potential. An output terminal is connected to one of the first and second electrodes of the transistor for deriving an output signal. The load lines of the transistor are set to a first operating point for both a first condition in which all three input signals are at a low voltage level and also a second condition in which two thereof are at a high level and the third is at a low level, and to a second operating point for both a third condition in which only one of the input signals is at the high level and the remaining two input signals are at the low level and also a fourth condition in which all of the three input signals are at the high level. The current conducted by the transistor is at a first level for the first operating point and at a second level, greater than the first level, for the second operating point.
