摘要:
A heating light source for a heat treatment device of the light irradiation type with high temperature uniformity on the wafer surface during heating and a small operating current and a lamp which is used for the heating light source. By using a light source in which several annular lamps are arranged concentrically within the same plane the need for a large device due to large currents is obviated. By arranging nonemission parts distributed over the entire peripheral direction of an annular filament lamp and not only on one side, and by arranging these filament light sources in the radial direction of a lamp in which several of these light sources are used distributed and not on one side, the irradiance on the entire wafer surface is made essentially uniform. These nonemission parts have a radiance which is controlled such that the irradiance on the wafer surface directly underneath the region in the vicinity of the insertion tubes in which the filament does not uniformly extend essentially agrees with the irradiance of the wafer surface directly underneath the nonemission parts.

Two shim plates provided for a friction pad are arranged to be slidable relative to each other in the circumferential direction of a disk, thereby suppressing the transmission of rotational force from the disk to a caliper through the friction pad and so forth during a braking operation. A friction pad including a lining and a backing plate is disposed between the disk and an outer leg portion of the caliper. An inner shim plate is integrally mounted on the back of the backing plate. An outer shim plate is disposed between the inner shim plate and the outer leg portion of the caliper in such a manner as to be slidable relative to the inner shim plate in the circumferential direction of the disk. During a braking operation, when the friction pad pressed by the caliper is circumferentially displaced by being dragged by the disk, the inner shim plate, together with the friction pad, slides relative to the outer shim plate, thereby reducing rotational force transmitted from the disk to the caliper.

A first a confocal optical microscope in which a good image with high contrast can be observed with which a bright image can be observed over a long time interval. The confocal optical microscope has a quarter wave plate arranged in an optical path between an imaging lens and an objective such that it is inclined relative to a reference optics axis extending between the imaging lens and the objective. Furthermore, the confocal optical microscope has a shortwave radiation attenuator for attenuating light radiated from the light source with wavelengths of less than or equal to 340 nm. The confocal optical microscope can form part of a length measuring device which can take a length measurement of a sample to be measured with high measurement accuracy and high reproducibility. The length measuring device also has a movable carrier, a carrier device for a sample to be measured, a computing device, a display device and a control device.

A method of casting a plurality of caliper forms by using a mold and a core member of a special design is presented. The core member 20 has axial sections 22A, 22B formed on its each end aligned parallel to each other, and the middle section 21 between the axial sections is provided with a depression section 24A for forming a teeth section 9 of the caliper form 17A. Between the depression section 24A and the axial section 22A, there is a depression section 24B opposing the depression section 24A for forming the other teeth section 9 of the other caliper form 17B. There are internal surface forming sections 27A, 27B for forming the internal surfaces of the disc pass sections 8, respectively, between the axial section 22A and the depression section 24A, for the caliper form 17A and between the axial section 22B and the depression section 24B for the caliper form 17B. This structure of the core member 20 enables to produce two caliper forms 17A, 17B with the use of one core member 20, and the configuration, of arranging the depression section 24B disposed between the depression section 24A and the axial section 22A, allows the middle section 21 to be made short, thus saving the material cost. The overall approach of the invented method contributes significantly to the efficiency of production of the caliper forms compared with the conventional approach.

The present invention relates to a process for continuously crystallizing fructose anhydride using a seed crystallization tank and a crystallization tank separated from each other, comprising feeding an aqueous fructose solution containing at least 90% of fructose and containing at least 87 W/W % of solid and an aqueous solution containing a great deal of crystals in an amount of 0.5 to 5 times that of said fructose solution into a seed crystallization tank equipped with a high speed agitator, mixing the mixture at 40.degree. to 50.degree. C. at a high speed, introducing the obtained mixture into a crystallization tank and gradually cooling the mixture under condition under which new crystals do not form spontaneously to thereby grow the crystals. The present invention can realize the crystallization at a low temperature of 40.degree. to 50.degree. C. or below and prevents the decomposition and the polymerization of fructose which often occur above 50.degree. C. by mixing an aqueous fructose solution and a great deal of crystals at a high speed, whereby large and uniform crystals of fructose anhydride can be obtained in an enhanced yield.
