Title: In-phase hybrid circuit
Inventor: TOHIRA KAZUSHIRO
IPC: H05K1/02
Filed: 1989-02-13
Abstract: PURPOSE:To manufacture an in-phase hybrid circuit capable of being used in various frequency bands without varying the pattern of a main substrate by changing the length of a strip line on a multilayer substrate. CONSTITUTION:A conductor for grounding is fixed at the center of a first substrate 550, to which a transmission line having a pattern in which phase is displaced by a quarter wavelength in microwave frequency is formed, while first and second substrates are arranged mutually vertically. When a device is used to frequency lower than said frequency, a conductor for grounding to which a transmission line having a pattern in which phase is displaced by the quarter wavelength in the frequency is shaped is passed through a groove 900 formed to the second substrate 750, and fastened so that the conductor and the second substrate are made mutually perpendicular. Accordingly, the length of a strip line on the multilayer substrate (the first substrate) 550 is changed, thus realizing an in-phase hybrid circuit capable of being employed in various frequency bands without altering the pattern of the main substrate (the second substrate) 750.

Title: Congestion control system in packet switching network
Inventor: OOISHI KIKUHIRO
IPC: H04L45/24
Filed: 1984-02-23
Abstract: PURPOSE:To enable shortening of packet transfer time and dispersion of load in a packet switching network by determining passage of sending out packet depending on alternative control information added to the packet and information of the state of congestion of adjoining packet exchange which is on the passage to destination when a relaying packet exchange received the packet. CONSTITUTION:In a transfer packet, alternative control information (cr) is added besides destination information (dn) and originating station information (on) to terminal transmitting packet (pkt). The alternative control information (cr) is set to logical value ''0'' to general packet that makes a detour to a packet exchange which is in the state of congestion, and set to logical value ''1'' to specific packet that does not make a detour. The relaying packet exchange A discirciminates alternative control information (cr) of arriving packet, and when it is set to logical value ''1'', sends out the packet to a relaying path L2 even when it is receiving congestion notice packet from a packet exchange B. Consequently, the packet is transferred to destination packet exchange C by the shortest route similar to the case where the packet exchange B is not in the state of congestion.
