A mass spectrometry unit of the present invention includes a mass spectrometry portion that detects ion current values of a gas to be measured according to mass-to-charge ratio, to thereby measure partial pressures of the gas to be measured. The mass spectrometry unit further includes: a control portion for preliminary storing a record of a mass-to-charge ratio of a specific gas that decreases a function of a specific portion of the mass spectrometry unit, in which if an ion current value with the mass-to-charge ratio of the specific gas detected by the mass spectrometry portion is not less than a predetermined value, the control portion outputs a warning signal denoting a functional decrease in the specific portion.

In a layout method for an LSI having a plurality of cells, automated arrangement of cells is performed on the basis of a netlist, which has cells and connection data therefor, and timing conditions, and, once a timing optimization processing is performed so that a plurality of cells are arranged on a chip, global wiring processing is implemented and the wiring congestion rate is analyzed. In addition, in small regions where a wiring congestion rate is so high that detailed wiring processing is judged to be difficult, cell rearrangement processing is implemented. Next, detailed wiring processing is performed with respect to the cells which have been rearranged. The rearrangement of cells is performed only in small regions with a high congestion rate, with the result that the overall cell arrangement in which timing is optimized is not changed markedly, whereby it is possible to reduce the probability of wiring being impossible in the course of the detailed wiring processing.

A multi-component glass doped with microparticles of CdS.sub.x Se.sub.y Te.sub.z, which can be used as a material for sharp cut filter, a material for infrared-transmitting filter or a nonlinear optical material. This glass has solved the problems of conventional glasses doped with microparticles, of (a) being low in microparticles concentration and accordingly having a low spectral characteristic when made into a thin filter and (b) being low in microparticles concentration and accordingly having low third-order nonlinearity, by containing microparticles at a high concentration, i.e. 5-50% by weight. The present invention relates to a process for producing the above multi-component glass doped with CdS.sub.x Se.sub.y Te.sub.z microparticles. This has solved the conventional problems that the chalcogen element(s) to constitute the microparticles is (are) vaporized at the step for obtaining a glass melt, by specifying (a) the material to become a glass matrix and (b) the atmosphere used for obtaining a glass melt.

Disclosed is a process for producing a copper through-hole printed circuit board, which comprises forming a required pattern on a copper-clad laminated plate using a resist ink soluble in an alkaline aqueous solution, immersing the copper-clad laminated plate in an aqueous solution of a salt of an alkylimidazole compound represented by the following general formula ##STR1## wherein R.sub.2 represents an alkyl group having 5 to 21 carbon atoms, R.sub.4 represents a hydrogen atom or a methyl group, and HA represents an organic or inorganic acid, to form on the copper surface of the copper-clad laminated plate an etching resist film composed of the alkylimidazole compound, drying the resulting copper-clad laminated plate, and then treating it with an alkaline etching solution.
