摘要:
A process for partially swapping real storage areas used by a program is utilized in a computer system which executes programs by multiprogramming under control of a virtual storage type operating system. A first portion of a real storage area, allocated to a program to be swapped out, remains allocated to that program while the contents of a second portion of the real storage area are saved in an auxiliary storage so that the second portion is deallocated from that program. The saved contents of the second portion stored in the auxiliary storage are loaded in the real storage when the program is to be swapped in.

In the size measurement of steel sections, a pair of two-dimensional rangefinders and a pair of one-dimensional rangefinders are arranged so as to sandwich a steel section consisting of a pair of flange portions and a web portion in a widthwise direction of the flange portion and face to each other, whereby a vertical distance ranging from the two-dimensional rangefinder to the flange portion and a vertical distance ranging from the one-dimensional rangefinder to the web portion are measured, respectively to calculate a deviation at center, a flange width and a web thickness from the above measured values. In this case, a laser rangefinder is used as each of the two-dimensional rangefinder and one-dimensional rangefinder.

The present invention provide a transmission system comprising a transmission apparatus for transmitting audio data of multi channels and auxiliary data required for playback of the audio data, and a receiving apparatus for receiving the audio data and the auxiliary data which are transmitted by the transmission apparatus. A multiplexer of the transmission apparatus creates block data that is composed of 8 frames, and first 1 byte of each frame is allocated to a header having Sync, OE and the like, the second byte is allocated to the auxiliary data including AUX data and copyright protect information, and remaining bytes are used to transmit the audio data. An encryptor carries out an encryption process for the second and later bytes of each frame, and a communication means outputs encrypted data. A communication means of the receiving apparatus receives the encrypted data from the transmission apparatus, a decoder decodes the encrypted data, and a demultiplexer demultiplexes the audio data and the auxiliary data. Therefore, this transmission system transmits multi-channel audio data of the DVD-Audio or the like efficiently on a transmission line using fixed length frames according to the MOST method, and takes measures for copyright protection of audio data.

Stream data and a command output from a drive device are individually packetized in a first packet processing unit. The stream data packet and the command packet are further multiplexed, and the multiplexed data is transmitted to a transmission path using a synchronous channel. When the command output from a decoding unit is packetized in a second packet processing unit, it is packetized by multiplexing flow control information output from the decoding unit, and is transmitted to the first packet processing unit using a synchronous channel of the transmission path. Based on this flow control information, reading/writing by the drive device is controlled.

The invention provides a sensor comprising a frame, a plurality of beams extending inwardly from said frame, a weight portion supported by the beams, a piezoelectric-resistor formed on each beam and an insulating layer that covers the piezoelectric-resistor. The piezoelectric-resistor has at least one bend, and a metal wiring is located on the insulting layer positioned at the bend. The metal wiring is connected to the bend via at least two contact holes formed in the insulating layer. Contact holes are formed in the insulating layer positioned at both ends of the piezoelectric-resistor, and a bridge circuit wiring is connected to the piezoelectric-resistor via the contact holes.

The present invention realizes streaming reproduction in an environment in which a communication speed changes due to a change in the position of a moving body such as a vehicle. A content reproduction device 10 includes: a plurality of communication units (a cellular phone 101 and a wireless LAN communication unit 104), each receiving a content transmitted in segments from a content transmission device over a communication path; a content reconstruction unit 113 that has a buffer 1130 in which each segmented data of the content received by each of the communication units is temporarily accumulated, and that reconstructs each segmented data accumulated in the buffer 1130 into the content; a reproduction unit 114 that reproduces, at a predetermined bit rate, the content reconstructed by the content reconstruction unit 113; and a communication control unit 110 that: calculates, for every predetermined time, target transmission speeds to be assigned for content reception performed by the respective communication units, based on free space in the buffer 1130 and the bit rate; and transmits a first request signal indicating the calculated target transmission speeds to the content transmission device via one of the communication units.

A display system (100) is provided which includes two display devices (101a and 101b); a coupling section (102) for coupling the two display devices such that one display device can be displaced relative to the other display device; a detection section (111-114) for detecting a value by which a position of the one display device relative to the other display device can be identified; and a display control section (115) for generating an image to be displayed on each of the one and the other display devices, based on the position detected by the detection section. The one and the other display devices display their respective images generated by the display control section.
摘要:
In a file system capable of reserving a storage area, disk fragments can be prevented and an insufficient file system area is hard to occur. A response time of writing a small size file can be shortened. When a file is written, a file size is compared with a plurality of preset threshold values and reservation is executed at a reservation size corresponding to the file size. If the reservation is failed due to an insufficient file system capacity, the reservation is again executed at an actual I/O size to effectively use the file system area. If the file size does not reach the preset smallest threshold value, the reservation is again executed at the actual I/O size and the reservation release process for the file equal to or smaller than the smallest threshold value is skipped.

A pillared clay possessing the ability to exchange cations is produced by a method which comprises heating a cation-exchange clay consisting of (1) silicate layers composed of octahedrons of alumina having part of the aluminum thereof substituted by magnesium or octahedrons of magnesia having part of the magnesium thereof substituted by lithium and tetrahedrons of silica and parallelly arranged in a state assuming negative electric charge and (2) exchangeable cations interposed between the silicate layers in a state retaining an electric charge balance with the negative electric charge of the silicate layers, thereby causing part of the exchangeable cations to be fixed in the silicate layers and inducing a decrease in the cation-exchange capacity of the clay, then cross-linking the interstices between the silicate layers of the clay, and thereafter causing liberation of the fixed cations.By causing a pillared clay which possesses the ability to exchange cations to be further cross-linked with pillars different from the pillars used in the clay, a pillared clay having pillars of a plurality of kinds is produced. By causing a pillared clay which possesses the ability to exchange cations to be further cross-linked with pillars identical with the pillars used in the clay, a pillared clay containing increased amounts of pillars is obtained.
