Title: Memory dump collection method and its execution device, and recording medium recording memory dump collection program
Inventor: NAGATA YOSHIHIKO
IPC: G06F11/34
Filed: 1999-07-22
Abstract: PROBLEM TO BE SOLVED: To shorten the stop time of a computer system when a fault occurs by restarting a processor after saving the dump data on a dump collection object processor in a fast storage and then outputting the saved dump data to a slow external storage. SOLUTION: A processor having a fault such as an OS panic transmits the data on a main storage 42 to a designated dump data saving processor 4. The processor 4 saves the received dump data in a dump data saving area 421 of the storage 42. When this saving operation is over, a dump data output processing part 412 is started to output the stored dump data to a dump file 51 of a slow external storage 5. Meanwhile, a system management processor 1 restarts the processor 2 where the dump data saving operation is over in parallel to the output of the dump data.

Title: Loop transmission system by token passing
Inventor: TOKURA NOBUYUKI
Filed: 1984-10-02
Abstract: PURPOSE:To detect missing of token quickly independently of the number of stations by using a function preventing circulation of a transmitted packet of a center station when a token is missing on a loop to lose a packet within two circulations in the loop. CONSTITUTION:When the token is missing due to a faulty transmission line while only the token is circulated, the token, a start delimiter and an end delimiter do not exist on the loop and the missing of token is detected within a timer value TTNT. When the token is missing after a station transmits a packet and releases the token, the transmitted packet is lost in the transmission station after one circulation in the loop. Even if a packet sender address has an error, since the packet is lost by the function preventing the circulation of the same packet of a center station CS for two times or over, the packet does not exist on the loop within the two circulations in the loop after token missing and the missing of token is detected after a timer time TTNT.

Title: Manufacture of semiconductor laser
Inventor: ISHIBASHI AKIHIKO
IPC: H01S5/00
Filed: 1993-08-23
Abstract: PURPOSE:To increase the output of a semiconductor laser by depositing dielectric films which do not allow hydrogen to permeate at resonator-length intervals on a wafer for semiconductor laser in which an active layer and clad layer are deposited on a substrate and heat-treating the wafer in an atmosphere containing hydrogen atoms. CONSTITUTION:A wafer is formed by successively depositing a P-clad layer 2, P-active layer 3, P-clad layer 4, P-intermediate layer 5, and cap layer 6 on a substrate 1. After depositing Sin, dielectric films 7 at resonator-length intervals on the wafer, the wafer is treat-treated for 30 minutes in the atmosphere of a mixed gas of AsH3, and H2 maintained at 750 deg.C in temperature and 76Torr in pressure. The hydrogen atoms H generated by the thermal decomposition of AsH3 in the gaseous phase and intruded into crystals in the P-clad layer 4 from the parts of the cap layer 6 where the dielectric films 7 are not formed suppress the diffusion of impurities by terminating defects which induce impurity diffusion or dangling bond near the impurities. Since no hydrogen atom H intrudes from the parts of the layer 6 where the films 7 are deposited and active Zn is diffused in the A-area of the P-active layer 4, a semiconductor laser thus constituted can make high-output operations.

Abstract: PURPOSE:To attain the accurate and efficient analysis of the temperature distribution of a conductive material due to inductive heating by considering the temperature change of the electromagnetic physical property value of an analyzing subject. CONSTITUTION:The temperature characteristic curve data on the electromagnetic/thermal physical property value of the steel stock are inputted to a computer together with the initial temperature of the steel stock.

Then the conductivity and the permeability are obtained from the initial temperature of the steel stock, and the metastable electromagnetic field analysis is carried out. Thus the Joule heat is calculated. Then the heat conductivity is obtained together with the heat capacity per unit accumulation and the heat transmittance. The transient temperature field analysis is repeated based on the obtained heat conductivity/transmittance and the Joule heat while the heat capacity and the heat transmittance are updated. Then the new conductivity and permeability of the steel stock are obtained based on the relevant temperature. Based on these coductivity and permeability, the metastable electromagnetic field analysis is carried out again and the Joule heat is calculated again for repetition of the transient temperature field analysis.
