Filed: 1995-09-13
Abstract: PROBLEM TO BE SOLVED: To provide a quadrupole mass spectrometry device allowing the mass of high-energy ions to be easily analyzed by arranging two sets of quadrupole electrodes at a pre-stage and a post-stage along the travel path of sample ions, and applying DC voltage as well as high-frequency voltage to respective quadrupole electrodes in a superposed state. SOLUTION: Two sets of quadrupole electrodes 11 and 12 are laid in series along the path of a sample ion beam 14 with the center axes of quadrupole electric field aligned. Then, the opposite electrodes of each set are wired to each other for application of the same potential thereto. Furthermore, conditions for DC voltage and high-frequency voltage applied to the quadrupole electrodes 11 at a pre-stage are determined on the basis of the second stable zone of the Mathieu's lines. Also, the conditions for each voltage applied to the quadrupole electrodes 12 at a post-stage is derived from the first stable zone of the Mathieu's lines. In addition, mass is roughly analyzed with the pre-stage quadrupole electrodes 11 and, then, analyzed with the post-stage quadrupole electrodes 12 under an enough resolution maintained, thereby providing a high resolution.

IPC: G11C29/04
Filed: 1993-09-25
Abstract: PURPOSE:To obtain the semiconductor device wherein the selection stop operation of a word line to be made redundant or the like is operated at high speed without affecting an ordinary word-line selection operation and the higher-speed of a Bi-CMOS static RAM or the like provided with a redundancy changeover circuit is promoted. CONSTITUTION:In a Bi-CMOS static RAM or the like which is provided with a redundancy changeover circuit, e.g. a corresponding inverted main word line MW0B is formed as a so-called word line, to be made redundant, which is replaced by a redundant word line. At this time, a fuse F1 which sets in to a nonselection level in a fixed manner, i.e., a high level, is installed at the inside excluding the output signal route of a unit main-word-line drive circuit UMD0 or the like. Thereby, the fuse F1 which is provided with a comparatively large sheet resistance value is excluded from a word-line drive route, and a load capacity with reference to the fuse F1 can be made comparatively small. As a result, the selection stop operation of the word line to be made redundant can be performed at high speed without affecting an ordinary word-line selection operation.
