Matrix processing method of shared-memory scalar parallel-processing computer and recording medium

In accordance with a parallel matrix processing method adopted in a shared-memory scalar computer, a matrix to be subjected to LU factorization is divided into a block D of the diagonal portion and blocks beneath the D diagonal block such as L1, L2 and L3. Then, D+L1, D+L2 and D+L3 are assigned to 3 processors respectively for processing them in parallel. Next, a block U is updated by adopting an LU-factorization method and C1 to C3 are updated with L1 to L3 and U. By carrying out this processing on the inner side gradually decreasing in size as blocks, finally, a portion corresponding to the D diagonal block remains to be processed. By applying the LU factorization to this D portion, the LU factorization for the entire matrix can be completed.

Radio paging receiver and message erasing method

Message data are picked up by using a decoder 2 from received signals received by a receiver portion 1 of a radio paging receiver, and stored in a RAM 4a of a CPU 4. An informing portion 9 informs a user of the message. The user designates any character sequences in the message stored in the RAM 4a by a character sequence designating unit 4b. A character sequence retrieving unit 4c retrieves whether or not designated character sequences are contained in stored messages. When the messages containing the designated character sequences are detected, a time counting unit 4d monitors whether or not a predetermined time has been lapsed after storage of concerned messages. An erasing unit 4e erases unnecessary messages stored in the RAM 4a from the RAM 4a after the predetermined time has been lapsed. Accordingly, the messages which are transmitted periodically and repeatedly to the radio paging receiver can be erased collectively and automatically and thus complicatedness in erasing the messages can be eliminated and also operability can be enhanced.

The present invention provides a gate-controlled tunneling bidirectional switch device without Ohmic-contact, which avoids a series of negative effects (such as current collapse, incompatibility with traditional CMOS process) caused by the high temperature ohm annealing process. Each insulated gate structure near schottky-contact controls the band structure of the schottky-contact to change the working state of the device, realizing the bidirectional switch's ability of bidirectional conducting and blocking. Due to the only presence of schottky in this invention, no heavy elements such as gold is needed, and this device is compatible with traditional CMOS technology.

Method of fabricating high voltage semiconductor devices with JFET regions containing dielectrically isolated junctions

A high-voltage field-effect device contains an extended drain or “drift” region having a plurality of JFET regions separated by portions of the drift region. Each of the JFET regions is filled with material of an opposite conductivity type to that of the drift region, and at least two sides of each JFET region is lined with an oxide layer. In one group of embodiments the JFET regions extend from the surface of an epitaxial layer to an interface between the epitaxial layer and an underlying substrate, and the walls of each JFET region are lined with an oxide layer. When the device is blocking a voltage in the off condition, the semiconductor material inside the JFET regions and in the drift region that separates the JFET regions is depleted. This improves the voltage-blocking ability of the device while conserving chip area. The oxide layer prevents dopant from the JFET regions from diffusing into the drift region and allowing the JFET regions to be accurately located in the drift region.
