Abstract:
A process for preparing a magnet roller comprising a plurality of bar-like magnet pieces in a high working efficiency and in an improved adhesion accuracy, which comprises the steps of regulating the bonding position of at least two magnet pieces by their outer peripheral surfaces and their end surfaces, applying an adhesive from the inner surface side of the magnet pieces to the adhesion faces of the magnet pieces for bonding one magnet piece to another magnet piece to form a magnet block, and bonding and fixing the magnet block to a shaft. At least one of the adhesion faces which are in contact with each other may have a plurality of grooves to facilitate penetration of the adhesive into the interface of adjacent two magnet pieces.
Abstract:
It has been difficult to achieve weight reduction while satisfying a required insulation property in a heat insulating material configured by alternately stacking a metal vapor-deposited sheet and a net. A heat insulating sheet comprises: a first thermal conduction suppressing layer that suppresses thermal conduction; a first radiant heat reflecting layer that is placed on one surface side of the first thermal conduction suppressing layer and reflects radiant heat; and a protruding portion protruding from a surface of the first radiant heat reflecting layer on an opposite side of a surface on which the first thermal conduction suppressing layer is stacked, the protruding portion containing a resin at least on its surface.
Abstract:
Provided are heat insulating sheets that may include a resin film having a metal layer and a nonwoven fabric including resin fiber, wherein the resin film and the nonwoven fabric are joined by through holes penetrating the resin film and the nonwoven fabric, and wherein a ratio (La/Lb) of an average distance (La) between the through holes in the resin film to an average distance (Lb) between the through holes in the nonwoven fabric is 1.001 or more and 1.10 or less. Further provided are manufacturing methods of a heat insulating sheet that may include a resin film having a metal layer and a nonwoven fabric including a resin fiber.

Abstract:
Provided is a poly(3-hydroxybutyrate) resin tube including a poly(3-hydroxybutyrate) resin, the tube having a wall thickness of 0.1 to 0.6 mm. The difference between the melting point peak temperature and the melting point peak end temperature in differential scanning calorimetry analysis of the poly(3-hydroxybutyrate) resin is preferably 10° C. or higher. Preferably, production of the tube includes the step of melting a poly(3-hydroxybutyrate) resin in an extruder, then extruding the resin from an annular die, and introducing the resin into water, the annular die temperature being set to a temperature between the melting point peak temperature and the melting point peak end temperature in differential scanning calorimetry analysis of the poly(3-hydroxybutyrate) resin.
Abstract:
A modified aliphatic polyester resin includes a poly(3-hydroxyalkanoate) resin. A ratio between a melt viscosity (Pa·s) and a drawdown time (sec) is from 2.0×10−2 to 5.0×10−1 (sec/[Pa·s]), and a z-average molecular weight/weight-average molecular weight ratio is less than 10.
Abstract:
The present invention relates to a transparent polyimide film containing a polyimide and a phosphate ester. The content of the phosphate ester based on 100 parts by mass of the polyimide is 3 parts by mass or more, preferably 5 to 100 parts by mass. It is preferable to use a phosphate ester that has a high birefringence reduction effect and with which a decrease in the tensile modulus of the film is small. In production of the polyimide film, it is preferable to employ a method in which: a solvent-soluble polyimide resin and a phosphate ester are dissolved in an organic solvent exhibiting solubility with respect to the polyimide resin to prepare a polyimide solution; the polyimide solution is applied onto a substrate; and the organic solvent is removed.
