摘要:
A cutting edge 24 is divided into a center area 28 including a V-shaped apex portion, a pair of intermediate areas 29 on the outer sides thereof, and a pair of side areas 30 on the farther outer sides thereof. The center area 28 has first teeth with the highest tooth height and second teeth with a smaller tooth height, the first teeth being situated at the apex portion and the second teeth being situated between the first teeth at a prescribed spacing around them as the center. A first straight line connecting the tips of the first teeth, a second straight line connecting the tips of the second teeth and a third straight line connecting the bases of the first teeth and second teeth are parallel, the second straight line being located between the first straight line and third straight line. The tips of the intermediate teeth of the intermediate area 29 are located on the second straight line or between the second straight line and third straight line. The tips of the side teeth of the side area 30 are located on the second straight line or between the first straight line and second straight line.

A center portion (30) of a V-shaped cutter blade (20) includes center large teeth (31) and center middle teeth 32 the tooth height of which is less than the tooth height of the center large teeth (31). End portions (50) of the cutter blade (20) each include first end teeth (51) and second end teeth (52) the tooth height of which is less than the tooth height of the first end teeth (51). Tooth tops of the first end teeth 51 of each end portion (50) are located on a straight line (L1), which extends through tooth tops of the center large teeth (31) located on one of the right half and the left half of the center portion (30).

摘要:
A wrapping film container, including: an elongated container body for housing therein a rolled self-tacky wrapping film, an opening provided to the container body along a longitudinal direction of the container body for pulling out a portion of the wrapping film therethrough, cutting means for cutting the pulled-out portion of the wrapping film and a film-holding section provided on a front face of the container body for preventing re-winding to an inside of the container, wherein the film-holding section comprises a laminate structure including a pressure-sensitive adhesive layer, a substrate layer, an adhesive layer and a self-tacky film layer, disposed sequentially from the container body side. The film-holding section is efficiently formed on the front face of the container body by using a label for forming film-holding section of a wrapping film container having a laminate structure including a self-tacky film layer, an adhesives layer, a base material layer, a pressure-sensitive adhesive layer and a separator layer, disposed sequentially from one side thereof, and exhibits a stable and consistent film-holding power.

摘要:
In the production of an aliphatic polyester by ring-opening polymerization of a cyclic ester, at least a latter period of polymerization is proceeded with by way of solid-phase polymerization, and the resultant aliphatic polyester is subjected to removal of residual cyclic ester. As a result, an aliphatic polyester with a minimized content of residual monomer is obtained.
摘要:
A method for correcting an instrumental error due to wavelength error of a spectroscope of an optical analyzer for measuring an optical density reflected from or transmitted through a dry analysis element. One standard color plate having a standard optical density OD.sub.ST is measured by an optical analyzer to be corrected to obtain an measured value OD.sub.M. A measured optical density OD.sub.S of the element applied with a sample through the optical analyzer to be corrected is corrected by using a ratio of OD.sub.M /OD.sub.ST to obtain a corrected measured value OD.sub.C of the sample. The standard color plate to be used contains an indicator dye contained in the non-reacted dry analysis element or a dye having an absorption spectrum same as or similar to that of the indicator dye in the measurement wavelength range. Another correction method in consideration of a layer coefficient of a dry analysis element is also provided.
摘要:
A dry-type analytical element suitable for measuring the activity of alanine aminotransferase in a liquid sample, characterized by incorporating a dye capable of absorbing the electromagnetic waves of 400 to 500 nm into at least one water-permeable layer. The coloring sensitivity of the dry-type analytical element does not increase substantially even under a fluorescent light, and thereby, an accurate measured value can easily be obtained.
摘要:
The immunoassay element for quantitatively analyzing an antigen by determining the change in enzymatic activity of an enzyme-labelled antigen or antibody caused by an immunological reaction. The immunoassay element comprises a substrate layer containing a non-diffusible substrate which forms a diffusible material in the presence of the labelling enzyme, and a reagent layer containing a fragmenting enzyme for further fragmenting the diffusible material into a lower molecular weight product. As the non-diffusible substrate, a substrate capable of reacting solely with the lebelling enzyme and incapable of reacting the fragmenting enzyme is utilized. When an endo-active glucosidase is used as the labelling enzyme, and an exo-active glucosidase is used the fragmenting enzyme in the reagent layer, the non-diffusible substrate of the substrate layer is preferred to be an endo type selectively reactive substrate, which means a substrate having a reactivity specific to endo-active glucosidase. Highly sensitive assay is realized with high accuracy and high reproducibility and good storage stability.

A dry analytical element comprising at least one water-permeable reagent layer and a porous spreading layer laminated in this order on a support, wherein at least one layer which is the water-permeable reagent layer, the porous spreading layer or an optional water-permeable layer contains a water-soluble polybasic amino carboxylic acid which is an ampholyte. By applying an analytical element of the invention, an analyte can be measured at a high sensitivity using a small amount of an enzyme, etc., and shelf file can be extended.
