Title: Control valve device of discharge pressure
Inventor: YAMADA RIYOUJI
IPC: F16K31/12
Filed: 1981-01-12
Abstract: PURPOSE: To discharge the pressure without a shock from a vent circuit and other high pressure circuit, by applying pressure of a flow outlet to one end of a spool through a throttle valve simultaneously providing a spring, moving the spool to a selective position, to the other end.  
     CONSTITUTION: In case of maintaining pressure of a pressure circuit 4, an open- close valve 7 is placed to a neutral position 7a, at this time a flow outelt 3 is also at pressure equal to high pressure in a flow inlet 2 and vent circuit 6, then a spool 9 presses a spring 13 and is placed at a neutral position 9a. In case of discharging the pressure in the pressure circuit 4, the open-close valve 7 is selected to a selective position 7b to connect the flow outlet 3 to a tank 8, however, pressure in one end chamber of the spool 9 is discharged to the tank 8 in a slightly slow state by the action of a throttle valve 10, thus the spool 9 is  pressed by the spring 13 and moved at relatively slow speed from the neutral  position 9a to a selective position 9b.

Title: Solar battery panel with two-dimensional deployment feature
Inventor: ARAI HIDETOSHI
IPC: H02S30/20
Filed: 1984-01-10
Abstract: PURPOSE:To realize a two-dimensional folding of a solar battery panel without using hinges or adding stress to the solar cells by a method wherein each panel of a solar battery is provided with a cutout so that there may be no lap at points where lines of folding meet. CONSTITUTION:A panel for a solar battery capable of two-dimensional deployment is provided with a cutout 7. That is, a rhombic region is formed at a point where a first line of folding 5 and second line of folding 6 cross each other at a right angle. Absence of such cutouts 7 creates distortion in the vicinity of the crossing of the two lines of folding, degrading the folding precision, and giving stress to solar cells. Presence of such cutouts 7 eliminates the lap at the point of crossing, which frees the panels from distortion, the solar cells from stress, and ensures a high folding precision. Further, this method eliminates the fear of low reliability attributable to peeling at the junction regions that may otherwise arise.

IPC: H04L12/46
Filed: 1999-01-08
Abstract: PROBLEM TO BE SOLVED: To attain the fast and highly reliable transfer of a packet by setting a routing path by evading an optional interface where the congestion occurred and based on the link state information which are held by the nodes distributed periodically in an entire network synchronously with each other and also on the interface information which is locally managed by every node. SOLUTION: A routing part 20 sets a rerouting path in a loop-free way at an optional destination by evading a congestion point and based on the node topology information describing the global IP addresses which are synchronously distributed in a network and the local congestion information reflecting the traffic load which is managed for every node and transferred via an intra- node interface. A route of S→A→B→E→J is the shortest route. However, some traffics are bypassed in a direct route of B→J and a route of A→C→J when the congestion occurs on the interfaces BE and AB respectively.
