A transfer film comprising a base film (11), a parting-agent layer (12), a protective film (13), and a metal film (14), the latter three being formed on the base film (11) in order, wherein the protective film (13) contains a softening agent such as a phosphate, an aliphatic monobasic acid ester, an aliphatic dibasic acid ester, or a dihydric alcohol ester. By using such a transfer film, a metal back layer is formed. Since the transfer layer of the transfer film has a surface resistivity of as high as 102-108 Ω/, the surface resistivity of the formed metal back layer is high, and discharge is suppressed.

Methods of treating, and/or improving impulse control disorder, which comprises administering to a living subject, a composition comprising chitosan as an effective ingredient, having a weight-average molecular weight of 80,000 to 100,000 and a number-average molecular weight of 30,000 to 40,000, as measured by gel permeation chromatography (GPC). Also provided are methods for giving an activity of repressing impulse to food products and drinks by putting said chitosan in the food products, drinks and the material therefor.
摘要:
An ink composition having a pigment in its droplets, which are adhered onto the surface such as glass, ceramics or polyester resins of a base material, always dispersed uniformly is ejected from a nozzle by an ink-jet method to directly form a prescribed pattern of a colored layer of a color filter on the surface of the base material.

To suppress pressure fluctuation caused by insertion of arms between disks, which arms support thereon magnetic heads, to reduce disk flutter to thereby reduce disk driving power in a magnetic disk apparatus, there are provided an open space not covered by a shroud, which constitutes a part of a housing structure to cover a side surface of a disk stack, and provided on a downstream side of the arms relative to an airflow moving along surfaces of the disks as the disks rotate, and a channel, which connects a space on an upstream side of the arms and the open space not restricted by the shroud on the downstream side of the arms, the channel being provided with a linear section, which has a rectifying effect on the airflow.
摘要:
A coating solution composition for forming a glass gel thin film, contains at least one material selected from the group consisting of a metal alkoxide and a polycondensate of the metal alkoxide, a coloring material, an alcohol solvent, and a dispersant having an adsorption material for the coloring material, soluble in the alcohol solvent, and having miscibility with the metal alkoxide, wherein the coloring material has an average particle size of 3 nm to 300 nm. A glass gel thin film obtained by sintering this composition at a temperature of 100.degree. to 300.degree. C. is excellent in water resistance, durability and has a high strength.
摘要:
An information display apparatus which accumulates arbitrary information inputted to a television receiver from the outside, superimposes the information in a memory on an ordinary video signal and displays the superimposed image on a television display in accordance with a calender timer built in the television receiver. A remote control unit is provided for inputting information to the information display apparatus from the outside. Memories are disposed in the information display apparatus and the remote control unit for accumulating arbitrary information. A calender timer is provided for serving as a reference for displaying information are also disclosed. Arbitrary information inputted from the outside can be displayed on a television display at a previously appointed date.

摘要:
A hydrodynamic grooved bearing device in which a shaft is inserted into a hole formed in a bearing housing and one of the shaft and bearing housing is rotated, thereby the rotated member being supported includes a plurality of grooves formed on the shaft or an inner peripheral surface of the bearing housing for generating a dynamic pressure of fluid filled between the shaft and the bearing housing. The plurality of grooves are arranged side by side with a substantially certain pitch in a direction of rotation. Each of the grooves comprises a pair of groove portions slanted relative to the direction of rotation such that a distance between the pair of groove portions becomes narrower towards the direction of rotation and a connecting groove portion connecting the narrowest distance between the slanted groove portions. The connecting groove portion is extended in a direction substantially perpendicular to the direction of rotation. The provision of the dynamic pressure generating grooves enables a high bearing load and a stable bearing performance with a minimum degree of whirling compared with conventional V-grooved bearing.
