Title: Packet flow control method and router
Inventor: YAMATO KATSUMI
IPC: H04L12/46
Filed: 1999-08-09
Abstract: PROBLEM TO BE SOLVED: To reduce a memory quantity required to store information for each flow by transferring packets, belonging to a plurality of packet flows to a path for an aggregate flow consisting of a bundle of the packet flows transferred to a router when the traffic characteristics as the aggregate flow are specified. SOLUTION: An incoming side router 11 of a path 35 bundles flows a, b to allow the path 35 to recognize them as the same flow. A router placed on the path 35 needs not to discriminate an incoming packet, as to which of the flows a, b it belongs by aggregating a plurality of flows passing through the same route and the router can conduct the routine processing and quality assurance control with respect to an assigned band for the incoming packet as one aggregate flow. Thus the time required to retrieve information corresponding to the flow of IP packets can be reduced.

Abstract: PURPOSE:To enable writing the same data into other elements by writing an usual data in the reference point storage element of a data propagation and propagating the data of the reference point storage element into other elements while making data propagation control transistors on to be in propagating states. CONSTITUTION:When all storage elements 8 are initialized to be '0's. data propagations between respective elements 8 are made possible by setting a signal 50 to an H and an address line A0 is turned 'H' and a data input 2 is set to an L. Then, '0' is written in the element 8 by supplying an L potential via a data line 4 and an H potential via an inverted data line 5 to the element 8 selected by the line A0 and becoming the reference point of the data propagation. In such a way, '0's are written in all elements 8 by repeating propagations in the direction 60 of the arrow via data propagation control transistors 40. At this time, signal collisions between elements 8 can be prevented because transistors of inverters 11, 12A are different in sizes. Further, when all elements 8 are initialized to be '1's. '1's can be also written in all elements 8 in the same way by setting the input 2 to 'H'.

Title: Phase locked loop oscillator
Inventor: TAKAHASHI YASUSHI
IPC: H03L7/107
Filed: 1987-09-11
Abstract: PURPOSE:To increase the output phase fluctuation by providing a means revising a preset value of a frequency divider forming a phase comparison frequency from an output frequency so as to reduce the output phase at re-pull-in from being shifted unidirectionally. CONSTITUTION:A phase comparator 1 counts a phase difference of an input frequency f1 and a phase comparison frequency f2 by using a period of a sampling frequency f0. A phase difference detector 11 controls a voltage controlled oscillator 4 based on the result of count to vary the feedback voltage so that the result of count during the locking state is zero. When the input is interrupted, the voltage controlled oscillator 4 starts self-running. When the input is recovered after the self-running, the phase of the input fi is retarded by phi1, due to the change in the transmission route or the cut-off of the line and the phase of the output f0 is varied by phi2 due to the frequency fluctuation during the self-running. In this case, the result of count of the comparator 1 is N shown in equation. In decreasing the preset of a frequency divider 12, the phase difference between the input fi and the phase comparison f2 is T or below. Thus, the shift of the output phase unidirectionally at re-pull-in is reduced.

Abstract: PURPOSE:To reduce the burden of the thermal expansion to bellows and to prevent occurrence of excessive thermal stress in an evacuation duct main body having a thick inner thickness at the time of baking by lining the inside of the duct with a metallic liner provided with the bellows at both ends. CONSTITUTION:A vacuum pump 3 is provided at the end section of an evacuation duct main body 11 and the inner surface of the duct 11 is coated with a cylindrical metallic liner 13 with a gap section 12. Bellows 14 and 15 are connected with both end sections of the liner 13 and the other end sections of the bellows 14 and 15 are welded to the main body 11. In addition, a heater 16 is fitted to the liner 13 on the main body 11 side. When the heater 16 is energized, the liner 13 is heated and the main body 11 is baked. Therefore, at the time of baking the main body 11, the heater 16 is energized and the liner 13 is heated to the baking temperature. Since the liner 13 only is baked in such way, deformation of the main body 11 by thermal expansion hardly occurs. Therefore, durability of the bellows 6 of the evacuation duct is sharply improved, because little deformation occurs in the bellows 6.
