Title: Preparation of high beta type silicon nitride powder
Inventor: KUWABARA HARUYOSHI
IPC: C01B21/068
Filed: 1989-05-02
Abstract: PURPOSE:To prepare the subject powder containing a reduced amount of unreacted metal silicon by adding silicon nitride powder containing a specific amount of beta-Si3N4 to metal silicon powder in a specified ratio and subsequently nitrogenating the mixture by a direct nitrogenation method. CONSTITUTION:Metal Si powder mixed with >=1wt.% of silicon nitride powder containing >=30wt.% of beta-Si3N4 is nitrogenated by a direct nitrogenation method, thereby providing silicon nitride powder having a high beta type silicon nitride ratio, containing a reduced amount of the unreacted metal silicon powder and containing an extremely reduced amount of impurities such as Al. When the ratio of the beta type silicon powder added thereto is <30wt.%, the ratio of the produced beta type silicon nitride is low and the unreacted metal silicon is increased, and when the amount of the silicon nitride added thereto is <1wt.%, the effect of the addition is not generated. Since the excessive amount of the silicon nitride content reduces the amount of the produced silicon nitride, the addition amount is preferably <=20wt.%.

Title: Incoming preference connection system
Inventor: OBARA MASAHIRO
IPC: H04Q3/62
Filed: 1979-09-04
Abstract: PURPOSE:To reduce the ineffective working during the busy state of the trunk at the circuit incoming side outside the region, by giving a preference connection to the incoming call given from outside for the final idle trunk of the branch board. CONSTITUTION:In case an incoming call is given from the outside-region trunk BWT while an originating connection is given by the branch board BD with use of the last n-th idle trunk among the n pieces of the intra-region trunk BDT, a busy state is born since the n pieces of the intra-region trunks are under use. In such case, the originating is given from the BD, and the state under which the trunk BWT is not caught yet is detected. Thus the originating connection from the BD is made ineffective, and an incoming connection is given to the incoming call by securing an idle state for the n-th trunk outside the region. Thus the preference connection is given to the incoming given from outside to reduce the ineffective working due to the busy state of the trunk at the circuit incoming side outside the region.
