摘要:
A liquid composition for the manufacture of a membrane, comprising a reaction product a cuprammonium cellulose with an ammonium or alkali metal salt of a polymer containing 10 to 70 equivalent percent of a carboxyl group and having a number-averaged molecular weight in the range of from 500 to 200,000, and a membrane is obtained by molding the composition in the form of a film, immersing the shaped article thus obtained in a dilute sulfuric acid solution thereby coagulating and regenerating it, subsequently immersing the shaped article in an strong alkali solution thereby expelling said ammonium or alkali metal salt of the polymer therefrom and forming therein fine pores substantially corresponding to the molecular weight of said salt.

Unstretched hollow fibers of cuprammonium cellulose for dialysis possessing a film structure having a porosity of 15 to 25%, a pore diameter of 25 to 40 .ANG., and an ultrafiltration ratio of 3.0 to 5.5 ml/mmHg.hr.m.sup.2 are obtained by extruding, coagulating, and regenerating a cuprammonium cellulose spinning dope having a cellulose concentration of 6.8 to 8.7% and a viscosity of 500 to 1,300 poises (at 20.degree. C.).

There is provided a camera-shake correction mechanism by which camera shaking is corrected for by moving an imaging device on a plane that is orthogonal to an optical axis and in directions that are mutually orthogonal. The mechanism includes a heat dissipating mechanism that diffuses heat from the imaging device into atmosphere from a rear surface of the imaging device.

A sole structure 1 for a shoe comprises an upper plate 2 that is disposed on the upper side of the structure 1 and that has upraised portions 20 projecting upwardly form opposite side edge portions of the upper plate 2, a lower plate 3 disposed below the upper plate 2, and a plurality of longitudinally separated connecting portions 4, 5 and 6 that are disposed between the upper plate 2 and the lower plates 3 to form voids 10 therebetween and that elastically connect the upper plate 2 with the lower plate 3. The upper end of the connecting portion 5 extends upwardly to the side surface of the upraised portion 20 of the upper plate 2 and a projecting portion 5b that projects in the longitudinal direction is provided at the extension 5a. The extension 5a and the projecting portion 5b are fixedly attached to the side surface of the upraised portion 20.

A magnetic recording medium includes a nonmagnetic support having a thickness less than 7 μm and a width of 8 mm; a ferromagnetic metal layer disposed on a surface of the nonmagnetic support; and a reinforcing layer disposed on the other surface of the nonmagnetic support. The magnetic recording medium has a flexural rigidity EI of 5.9×10−8 to 1.3×10−7 N·m (6.0×10−4 to 1.3×10−3 g·cm). The flexural rigidity EI is determined by the following equation: EI=(π/4−2/π)·W·a3/d·b×9.8×10−5 (wherein W is a load that causes an annular test piece having a radius of a cm and a width of b cm which is prepared by cutting a magnetic sheet formed of the magnetic recording medium to undergo a radial displacement d of 0.2πa).
摘要:
A shared memory access function providing unit of each of a plurality of host computers of a network device receives an access shared memory request from an application and issues the access shared memory request to an FC switch. An access shared memory request identifying unit of the FC switch determines whether the request from the host computer is an access shared memory request, and if the request is an access shared memory request, a shared memory control unit controls the access to a shared data memory unit based on the access shared memory request.
摘要:
An athletic shoe includes a sole, an upper, a plurality of band-shaped members, and a fastening member. The upper has a toe portion, a heel portion, a forefoot portion and a lower periphery. The upper is secured to the sole and has a plurality of elongated through holes at regions except the toe portion and the heel portion. The band-shaped members are secured to the sole or the lower periphery of the upper and extend upwardly toward an instep of a foot of a shoe wearer. The fastening member is connected to each upper end of the band-shaped members.

A disc device has a movable mechanism used for moving a carriage carrying a disc so that the carriage either projects from an apparatus or is inserted into the apparatus. The disc carried by the carriage is exposed for an operator to handle the disc when the carriage projects from the apparatus. The disc carried by the carriage is contained in the apparatus after the carriage has been inserted into the apparatus. A rotating unit rotates the disc carried by the carriage and an accessing unit accesses the disc carried by the carriage. The disc device is incorporated into the apparatus. A locking mechanism locks the carriage in the apparatus, and a releasing unit causes the locking mechanism to release locking of the carriage in the apparatus. The releasing unit causes the rotating unit to stop rotating of the disc and also causes the accessing unit to stop accessing the disc, prior to each time the releasing unit causes the locking mechanism to release locking of the carriage in the apparatus. The locking mechanism is contained in the carriage.
