Abstract: A preceramic polymetalosilazane substantially free of Si-O groups is produced by reacting a polysilazane with a metal alkoxide in the presence of an alkylsilazane or alkylsilane. The preceramic polymer gives a high strength and heat resistant ceramic body which remains amorphous when calcined at 1,600.degree. C. for 10 hours in the atmosphere of nitrogen.

Abstract: Silicon nitride based ceramic fibers containing Si, N, O and at least one metal M in amounts providing the atomic ratios N/Si of 0.3 to 3, O/Si of 0.0001 to 15 and M/Si of 0.001 to 5 and exhibiting an X-ray small angle scattering such that the ratio of the intensity of the small angle scattering of the fibers to that of air is 1 to 20.

Abstract: In an authentication method for two programs which are executed when it is confirmed by authentication that a user is a valid user, pre-registered first reference data is acquired when authentication is performed for a first program to be activated earlier, and authentication data inputted by a user when the authentication for the first program is performed is acquired. Authentication for execution of the first program is performed with the use of the first reference data and the authentication data. Pre-registered second reference data is acquired when authentication is performed for a second program to be activated later, and authentication for execution of the second program is performed with the use of the second reference data and the authentication data already acquired at the authentication for the first program.

Abstract: When a personal computer system user carries out an OS shutdown, a BIOS does not turn off power, but reboots the system by a software reset to execute a POST, so that the state of the system immediately before starting the launch of the OS after completion of the POST is held in a volatile memory, and the system is shifted to a power saving mode. Subsequently, when the system is booted, the BIOS performs only restoration processing from the power saving mode while omitting the POST execution, and at once launches the OS, thereby shortening the system boot time by omitting the POST execution when the system is booted. Thus, POST processes are performed after the OS shutdown, a state that the POST has been completed after rebooting is held in the volatile memory, and then the system is placed into a state of power saving mode.

Abstract translation: 当个人计算机系统用户执行操作系统关机时，BIOS不会关闭电源，而是通过软件重置来启动系统以执行POST，以便在完成操作系统之前立即启动系统的状态 的POST保持在易失性存储器中，并且系统转移到省电模式。 随后，当引导系统时，BIOS在省略POST执行时仅执行从省电模式的恢复处理，并且一次启动OS，从而通过在系统引导时省略POST执行来缩短系统启动时间。 因此，在OS关机之后执行POST处理，在重新启动之后POST完成的状态被保存在易失性存储器中，然后系统被置于省电模式的状态。

Abstract: Silicon nitride fibers having a carbon content of 5 weight percent or less have high heat insulating properties and favorable mechanical properties and are useful as heat resistant, highly insulating materials or reinforcing agents for composite materials, particularly in the aerospace industry. Such high purity silicon nitride fibers are produced by spinning a solution of perhydropolysilazanes, an inert solvent and a spinning agent into fibers, preferably continuous fibers, and firing the spun fibers at 800.degree. to 1300.degree. C. in an inert atmosphere to form silicon nitride fibers of high purity.
