Title: Sample analysis with successive quanta timing code
IPC: G01N21/64
Filed: 1999-11-03
Abstract: In analyzing radiation from a communication link, single-photon counting can be used to advantage especially at low levels of radiation energy, e.g. in the detection of optical radiation. Preferred detection techniques include methods in which (i) received optical radiation is intensity-modulated in accordance with a preselected code, (ii) wherein it is the optical radiation which is intensity-modulated with the preselected code, and (iii) wherein the radiation modulated with a preselected code is received. For registration of the signals received by a sensing element of a single-photon detector, time of arrival is recorded, optionally in conjunction with registration of time intervals. Advantageously, in the interest of minimizing the number of pulses missed due to close temporal spacing of pulses, D-triggers can be included in counting circuitry.

Abstract: PURPOSE: To make a chip size small by reducing the layout area of a memory cell array of a semiconductor memory. CONSTITUTION: First transistor columns where transistors, by which any one of memory cell columns and an input/output circuit are selectively connected, are serially-connected are arranged. One of the transistors operates as a switch, and the other transistors, whose sources and drains are short-circuited, function as wiring. In the first transistor columns, a plurality of transistors are formed in advance. Because it is not necessary to selectively form only transistors to operate as a switch, it is not necessary to form a region for ion implant for forming the source/drain for each transistor. As a result, an arrangement space of transistors can be set without taking a layout rule of a diffusion layer region into account. Because the transistors are densely arranged, the layout area can be reduced and thus the chip size of the semiconductor memory can be made small.

Abstract: PURPOSE: Provided are a novel and useful ester group-containing tertiary amine compound which, when used as additives in chemical amplification photolithography, yields photoresist having a high resolution and an excellent focus margin, and a method for preparing the same. CONSTITUTION: The ester group-containing tertiary amine compound represented by the following general formula 1(wherein n is 1 or 2; and R1 and R2 each independently represents a straight-chain, branched or cyclic alkyl group of 1 to 20 carbon atoms which may contain an ether, carbonyl or carbonyloxy group). The ester group-containing tertiary amine compound is prepared by the steps of subjecting a primary or secondary amine compound represented by the following general formula 5 to Michael addition to an acrylic ester compound represented by the following general formula 6(wherein n, R1 and R2 are same as the formula 1).
