摘要:
A priority control register 104 dynamically controls the internal transition state based on the issuability state of a memory request obtained in the memory request issuability signal generation unit 106 and retaining state of the memory request in the REQ_BUF 102 obtained by each of determination circuits 105 #2 through #5. Thus, the jump control of the priorities corresponding to the access regulation of the DRAM module 109 can be realized.

A medical reporting system includes a display panel for displaying plural CT images. A ROI setting unit designates a region of interest in the CT images. A group setting unit sets a group of specific CT images having the region of interest among the CT images, to generate group information of the group. A report editor displays a note area for inputting a note related to the specific CT images. A memory stores a text location of the note area assigned to the group information, and stores location information of the region of interest in the specific CT images. Furthermore, a first terminal device has the report editor, the ROI setting unit and the group setting unit. A second terminal device communicates with the first terminal device on line. A reporting display panel displays at least the specific CT images and the note.

A multicast data communication system is provided that has high security, and prevents problems such as an attack by a malicious user creating a great number of meaningless tables at nodes in the network. Clients regularly transmit request packets toward a server; a node receives the request packet, and subsequently receives a delivery-table-creation packet or a delivery packet from the server; if the node has no delivery table corresponding to the server, the node creates the delivery table, registers the addresses of the clients, and their request packet arrival times, and regularly transmits the request packet toward the server; when the node has received a delivery packet from the server, the node duplicates and delivers the delivery packet only to those clients whose request packet arrival times, registered in the delivery table, are within a fixed period from the arrival of the delivery packet.

A method of making a semiconductor device including a semiconductor chip having a plurality of pads, and a lead frame having a plurality of leads. Each of the plurality of leads has a mounting surface for mounting the semiconductor device, a wire connection surface having a thick portion, and a thin portion whose thickness is thinner than the thick portion. The length of each wire connection surface was furthermore formed shorter than the mounting surface, by arranging so that the thin portion of each lead dives below the semiconductor chip, securing the length of the mounting surface of each lead, a distance from the side face of the semiconductor chip to the side face of a molded body of the semiconductor device being shortened as much as possible, and the package size is brought close to chip size, with miniaturization of QFN.

The yield of semiconductor devices is to be enhanced. A tray is provided with a plurality of pockets each capable of accommodating a wafer level CSP, and each of the pockets is provided with a base for supporting a plurality of bumps of the wafer level CSP and side walls formed around the base. In the step-to-step carriage in the post-production process of the manufacture of wafer level CSPs and on like occasions, the base supports not the organic film but the plurality of solder bumps. For this reason, it is made possible to prevent the organic film from being flawed or coming off and adhering to the product as foreign matter, and as a result the quality and yield of the wafer level CSPs (semiconductor devices) can be improved.

The package size of a semiconductor device is brought close to chip size, and a miniaturization is aimed at. Including a semiconductor chip having a plurality of pads, a plurality of leads having a mounting surface and a wire connection surface, having a thick portion, and the thin portion whose thickness is thinner than a thick portion, and with which the length of each wire connection surface was furthermore formed shorter than a mounting surface, a plurality of wires connecting leads with a semiconductor chip, and a molded body formed with resin, by arranging so that the thin portion of each lead dives into the lower part of a semiconductor chip and connecting the lead and the semiconductor chip with the wire by reverse bonding, securing the length of the mounting surface of each lead, distance from the side face of a semiconductor chip to the side face of a molded body is shortened as much as possible, package size is brought close to chip size, and the miniaturization of QFN 5 is aimed at.

A computer system comprises program products represented by a database management system, a first dictionary for registering and managing the definition data required for executing each of the program products and a second dictionary for storing and managing the structure definition data of the first dictionary. Each of the program products, for example a database system and a system development support tool, has added thereto in advance their structure definition data relating to all the definition data including the data required for executing each of the program products. The computer system creates the first dictionary on the basis of the structure definition data held by the program products in response to the demand for creating the first dictionary.
摘要:
Synthetic stevensite composed of stevensite-type sodium magnesium phylosilicate of which metallic components consist essentially of magnesium, sodium and silicon. The synthetic stevensite is characterized by having an X-ray diffraction peak at a spacing of 16 to 26 .ANG. when treated with ethylene glycol. It can be produced by a process comprising hydrothermally treating an aqueous composition containing basic magnesium carbonate and a silica-sodium component selected from the group consisting of (i) sodium silicate, (ii) sodium silicate and amorphous silica, and (iii) amorphous silica and sodium silicate.
