    摘要: A hemoglobin sampler for use with stool samples for clinical tests and diagnoses of the digestive tract diseases in mass screening, etc. by securely sampling and collecting occult hemoglobin with water content from the stool samples without being hindered by the undigested solid content of stools. The sampler has a core member consisting of a porous fiber bundle made up of a plural number of synthetic fibers bundled in the longitudinal direction thereof, a rod of a suitable length provided with a thermosetting synthetic resin sheath at the outer periphery of the core, one end of the rod forming a sample absorbing member with a suitable surface area and small diameter made up of the above mentioned porous fiber bundle. The sampler can quantitatively sample occult hemoglobin with water from stool samples of various properties, thereby offering an easy sample method for the subject and stable specimen for tests. Thus, the utility of the test method can be fully exerted and the sampler is quite useful for clinical tests and mass health screening.

    摘要: Method of manufacturing synthetic resin pen nibs is disclosed, which pen nibs may suitably be employed in writing instruments for fine lettering or drawing fine lines. The pen nibs are formed of thermoplastic crystalline synthetic resin, e.g. polyethylene terephthalate resin, which is extruded from a molding die and subjected to rapid cooling to form a continuous rod in amorphous state. The rod is axially stretched under predetermined temperature condition to achieve oriented crystallization of the resin molecules, and is further heat-treated such that non-oriented fine crystals are dispersed and grown between oriented crystals and remaining amorphous regions. Pen nib thus obtained has highly improved physical and chemical properties.

    摘要: Thermoplastic synthetic resin pen nib is disclosed, which may suitably be employed in writing instruments for fine lettering or for drawing fine lines. The pen nib is formed of thermoplastic crystalline synthetic resin, e.g. polyethylene terephthalate resin, whose molecules are in a specific mixed cystallization structure obtained by controlling the crystallization. This structure consists essentially of molecularly oriented crystals, non-oriented fine crystals dispersed and grown between the oriented crystals, and remaining amorphous regions, and provides the pen nib with highly improved physical and chemical properties.
