Title: Automatic chemical analyzer
Inventor: OHASHI AKINAMI
IPC: G01N35/00
Filed: 1985-12-19
Abstract: PURPOSE:To achieve a higher measuring accuracy, by correcting measured values of a sample pinched between samples with the known concentration by a correction factor calculated based on the measured value and the known concentration of the samples with the known concentration to automatically correct secular changes of measurement data. CONSTITUTION:A measuring section 1, first, measures known samples A, A and A as control 1, known samples B, B and B as control 2, then, samples X1-Xn and finally controls 1 and 2. This measurement is repeated. Measurement data are sent to a data processing section 2. The processing section 2 stores the known measured values of the controls 1 and 2 arranged before and after the samples X1-Xn and the measured values obtained from the measuring section 1 to determine a correction factor. In this manner, secular changes within one group are determined by average from a data of the known sample arranged before and after this one group, a correction formula is obtained from data values of known samples. Thus, correction for secular changes can be done about a desired sample.

Abstract: PURPOSE: To make phase distribution uniform so that it may be considered to be a spherical wave emitted from a certain point, by designing second and third total reflection mirrors so that the virtual image of a center circle at the center of the beam waist of a laser beam being in the ring cylindrical part in a laser medium gathers at a point near above the central axis of the laser medium. CONSTITUTION: A total reflection mirror parts of whose conical surface are the surfaces of total reflection mirrors 3 and 4 is thought of. On this occasion, beams emitted from wave directing path ends 24 and 25 and reflected by the total reflection mirrors 3 and 4 can be considered to be beams emitted from a virtual image 26 at the upper part of a wave directing path end and that 27 at the lower part of the wave directing path end. At this time, it is possible to make the center coincide with the end surfaces of the virtual images 26 and 27 by adjusting the angles of the total reflection mirrors 3 and 4. When design is done in this way, it is possible to treat a beam emitted from the end of a circular wave directing path equally with one emitted from a certain point effectively. Namely, its wave surface is considered to be a spherical wave, and can be made uniform.

Filed: 1990-10-25
Abstract: PURPOSE:To eliminate deterioration of characteristics even if a pinhole is generated in a dielectric barrier layer by depositing the layer on a second region having a high permittivity and a semiconductorlike band structure, conducting a process for reducing the permittivity of the surface of the region exposed in its lower surface via the pinhole of the layer, and depositing a first region having conductivity. CONSTITUTION:An Si barrier layer 2 is deposited on an Nb-doped SrTiO3 layer 1 having high permittivity and a semiconductorlike band structure. Since the layer 2 is formed extremely thinly in the degree of passing carrier by tunneling, pinhole 3 is not entirely eliminated. Then, a sample is removed from a sputtering unit, dipped in HF:H2O 5 filled in a vessel 4, cleaned with pure water, then dried, again mounted in the sputtering unit, and an Nb layer 7 is deposited. A low-permittivity region 6 is formed on the layer 1 exposed in the bottom of the pinhole 1 of the layer 2 by processing in aqueous solution of an acid.

Filed: 1989-10-31
Abstract: PURPOSE:To obtain bright recorded images having a high density without generating white voids while the uniformity at the time of all mark recording is maintained by incorporating methyl silicon powder of a specific particle size into a dielectric layer. CONSTITUTION:The dielectric layer essentially consisting of an insulating resin and pigment is formed on a conductive base. The methyl silicon powder having 2 to 15 mum average particle size is incorporated into the dielectric layer. The methyl silicon powder has excellent dispersibility in an org. solvent and does not generate flocs in a solvent and, therefore, has the characteristic that the unequalness and white voids at the time of all mark recording hardly arise even with the powder of the large average grain sizes. A marked effect is obtd. particularly if the powder having such specific particle size is selectively used. The electrostatic recording body which has the high recording density, is free from the white voids and has the low polishing property of multistylus electrodes is obtd. in this way.
