Title: Improving charging criteria for a call in a cellular mobile network
Inventor: TUOHINO MARKKU
IPC: H04Q3/00
Filed: 1997-06-27
Granted: 1999-07-21
Abstract: If the location cell of a calling subscriber (MS-A) or a called subscriber (MS-B) belongs to a set of special cells (CS) at the beginning of a call, a cheaper tariff is applied. According to the invention, the charging criterion is updated in the beginning and during the call. If a subscriber roams from the area of a public network cell to the set of special cells (CS), the cell information propagates to the MSC of the called subscriber. The MSC and/or service control SCP compares this cell information with the set of special cells (CS) and determines that the new cell of the called subscriber belongs to the special cells (CS), due to which the tariff can be changed. Information on the called subscriber's changed cell type is transmitted to the mobile switching centre (MSC, stage 3) of the calling subscriber.

Title: Taper tap for pipe of material of high hardness
Inventor: KATO KAZUMI
IPC: B23G5/06
Filed: 1998-10-31
Granted: 2001-04-11
Abstract: A high durability taper tap for pipe threads, which can cut threads in a pipe, made of a hard material with the hardness of approximately 50 HRC is provided. The sum SIGMA gamma of the width angle of cutters is set approximately 130 DEG. By setting the width of each cutter large, a high strength and rigidity are achieved. Since the rake angle of the cutting edge alpha is set approximately -20 DEG, the cutter angle beta defined by the rake face 8 and the peripheral relief becomes more than 90 DEG so that the strength and rigidity of the cutting edge 6 are enhanced. In addition, since the taper of the bottom of the flutes 4 is set in a ratio of 1/16, approximately equal to that of the taper of the thread portion 2, the rake angle alpha of all of the cutting edges 6 from the smaller end to the larger end of the thread portion 2 becomes equal so that all of the cutting edges 6 can equally cut the threads. Further, the diameter Df of the bottom of the flutes of the top end portion 1a is set approximately 60% of the smaller end of the thread portion 2, which is larger than that of the common tapping tool. Owing to this configuration, the taper tap for pipe threads of hard material having an excellent strength, rigidity and wear-resisting property can be achieved.
