In a storage area network (SAN), when a host accesses a storage system, the host is certified to restrict any unauthorized access. The storage system includes an access setting section and a certifying section to restrict accesses from respective hosts. When a host accesses data on a disk, the host issues an inquiry to a file server program of a host to receive information of a physical location of a file containing the data on the disk. The host accesses the disk according to the information. Simultaneously, the file server program allows, by a disk management program, the access to the area specified by the access request from the host.

A semiconductor memory includes a plurality of memory arrays and a plurality of sense amplifiers arranged alternately with respect to each of the memory arrays. The sense amplifiers are coupled to bit lines of the memory arrays to form an open bit line type semiconductor memory. In conjunction with this structure, two memory arrays at end portions of the semiconductor memory device are both selected together, whereas a memory array in an inner portion of the semiconductor memory device is selected independently.

In an image reading apparatus for reading an original image using a light source containing a plurality of color components, a control pulse for dimming the light source is generated by pulse-width modulation symmetrically with respect to a reference timing (for example, the central position in one storage time or the storage start timing) in one predetermined storage time of a line sensor.

A database update method for a computer system having a host computer and a storage sub-system where a database is maintained is disclosed. The storage sub-system includes first and second storage units containing duplicated data. The host computer accesses the first storage unit for data reading and the second storage unit for data writing. If incomplete processing to read is in process when an access request for data writing occurs, the host computer commands the stop of volume duplication of the first and second storage units and issues a write request. In response to this command, data is stored into only the second storage unit. Upon the completion of both read and write processing, the host computer commands the restart of volume duplication of the first and second control units to reflect the data stored into the second storage unit in the first storage unit.

A reader controller is connected to a printer controller which controls a engine controller provided in a printer. The printer includes a controlling unit for controlling a document reader which reads documents, a receiving unit for receiving a command for the engine controller from the printer controller, and a counting unit for counting a number of documents processed by the reader controller in accordance with a control of the controlling unit, and counting a number of sheets processed by the printer controller in accordance with the command received by the receiving unit. The printer further includes a causing unit for causing a display of the reader to display the number counted by the counting unit.

A picture signal transmitting system using a CATV network sends a picture signal from a transmission path to subscribers by using a radio transmitter and receiver, and in the picture signal transmitting system, there is no physical wire connection from a tap off of the transmission path to subscribers. The picture signal transmitting system using a CATV network includes a CATV center, a first radio transmitter and receiver connected to said CATV center through a CATV transmission path, and provided near a subscriber's house for concurrently sending out a side band signal obtained by up-converting a picture signal of a frequency bandwidth including a plurality of channels with a local oscillation signal of which level is larger than that of said side band signal, and the local oscillation signal, and a second radio transmitter and receiver provided in the subscriber's house for separately receiving the picture signal and the local oscillation signal sent out from the first radio transmitter and receiver, and down-converting the frequency bandwidth of the received picture signal with the received local oscillation signal to an intermediate frequency bandwidth.

To reduce both the noise level according to separation or short-circuitng of the electrical supply line of the sense amplifiers and the electrical supply line of the word line driving circuit and to effectively prevent destruction of the stored data in the nonselecteded memory cell. Electrical supply line (Vssw) of the power supply voltage with respect to word line driving circuit (SWD) and electrical supply line (Vssa) of power supply voltage with respect to sense amplifier driving circuit (SAD) are arranged separately in memory array area 2 (e.g., in the space in the row direction of memory array (SMAx,y)) and connected to shared electrical supply wiring (Vsso) within peripheral circuit area 3.

An information processing device is provided that includes a display portion, a user recognition portion, a button selection portion, and a display control portion. The display portion displays at least one function button that is related to a function that the information processing device is capable of performing. The user recognition portion recognizes a user who is operating the information processing device. The button selection portion selects, from among the at least one function button that is displayed on the display portion, at least one function button that corresponds to the user who has been recognized by the user recognition portion. The display control portion moves the function button that has been selected by the button selection portion from an initial position on a display screen of the display portion such that the function button is close to a specified position on the display screen.

A pattern data examination method and system capable of accurately and speedily examining a circuit pattern without failing to extract pattern contour data are provided. While pattern comparison is ordinarily made by using a secondary electron image, a contour of a pattern element is extracted by using a backscattered electron image said to be suitable for observation and examination of a three dimensional configuration of a pattern element, and pattern inspection is executed by using the extracted contour of the pattern element. More specifically, pattern inspection is executed by comparing a contour of a pattern element with design data such as CAD data to measure a difference between the contour and the data, and by computing, for example, the size of the circuit pattern element from the contour of a pattern. From two or more backscattered electron images formed by detecting backscattered electrons at two or more different spatial positions, pattern contour data contained in the backscattered electron images may be obtained.
