A CPU 80 controls data transfer from a first device to a second device in a kernel mode. A main memory 90 stores data to be transferred from the first device to the second device. The CPU 80 has: a first device control means 81 which controls the first device; a second device control means which controls the second device; and a data transfer control means 83 which makes a read instruction which instructs the first device control means 81 to store data read from the first device in the main memory 3, and makes a write instruction which instructs the second device control means 82 to write the data stored in the main memory 3 in the second device.

A plate for a magnet cylinder includes a main body, a nonmagnetic portion, and a magnetic piece. The main body is formed of a flexible thin plate-like magnetic material to be magnetically mounted on the outer surface of a magnet cylinder. The nonmagnetic portion is projected from one end of the main body. The magnetic piece magnetically sandwiches the nonmagnetic portion against the outer surface of the magnet cylinder.

Provided is a mesoporous silica film, including a structure represented by SiO(2-n/2)Xn (where X represents a group formed of at least one kind selected from the group consisting of an alkyl group, a fluorinated alkyl group, and fluorine, n represents an integer of 1 or more and 3 or less) in a surface layer of the mesoporous silica film, in which: an element component ratio (A1/S1) of sum of number of carbon atoms and number of fluorine atoms (A1) to number of silicon atoms (S1) in the surface layer is 0.1 or more; and an element component ratio (A2/S2) of sum of number of carbon atoms and number of fluorine atoms (A2) to number of silicon atoms (S2) in an inner layer of the mesoporous silica film is smaller than the element component ratio (A1/S1).
摘要:
According to one embodiment, a solar heat collecting apparatus comprises a first heat exchanging unit and a second heat exchanging unit. The first heat exchanging unit includes a first pipe through which a heat medium flows and a first heat receiving face which receives heat of sunlight reflected by a plurality of reflecting units. The first heat exchanging unit heats the heat medium flowing through the first pipe by using heat of the first heat receiving face. A second heat exchanging unit includes a second pipe through which the heat medium heated by the first heat exchanging unit flows, a second heat receiving face which receives heat of the sunlight reflected by a plurality of reflecting units, and a nozzle provided to the second pipe to discharge the heat medium flowing through the second pipe toward a back face of the second heat receiving face.

To accelerate the booting time of a computer by a booting method using a communication network, a boot-up main memory image of an OS and application programs is used to boot a computer. The main memory image is managed in one batch on a server, and is regularly updated with the latest programs. When booting up the computer, only an initial load image which is the minimum part of the main memory image necessary to start the system is loaded, and remaining parts of the main memory image are suitably loaded in an on-demand manner after the system starts operating.
摘要:
The present invention provides a core-sheath compounded yarn constituted from a high tenacity and high heat-resistant fiber and other dyeable fiber and/or dope-dyed yarn where the high tenacity and high heat-resistant fiber is arranged as a core yarn while other dyeable fiber and/or dope-dyed yarn are/is arranged in a substantially untwisted state and the surroundings thereof are spirally covered by dyeable fiber and/or dope-dyed yarn. A woven/knitted fabric where the core-sheath compounded yarn is at least partially used is also provided.
摘要:
An optical information recording and/or reproducing apparatus is provided which can, with the help of the same apparatus, record information on both an information recording area of an information recording medium for hologram and an information recording area of an existing optical disc typified by BD, DVD or CD and/or reproduce the information recorded on both the information recording areas. The optical information recording and/or reproducing apparatus performs recording and/or reproduction of information on and/or from a hologram memory disc and an optical disc by means of an optical pickup and has a stepping motor for driving the hologram memory disc and a DC motor for driving the optical disc.
