Title: Manufacture of copper alloy member
Inventor: ONO ATSUMI
IPC: B22D11/128
Filed: 1986-04-30
Abstract: PURPOSE:To manufacture continuously cast billet in a high yield of product, by using a heated mold and by carrying out cold or warm working and then heat treatment at a specific temp. at the time of subjecting a molten Cu alloy containing a carbide-stabilzing element such as Cr, Zr, etc., to continuous casting in a mold made of graphite. CONSTITUTION:The molten Cu alloy 3 containing 0.1-1.2% Cr or 0.05-0.5% Zr as carbide-stabilizing elements is poured into a horizontal continuous casting mold 1 made of graphite, which is drawn out of the outlet 1a of the mold in the form of a continously cast billet and then is cooled by cooling means 6. At this time, the continous casting mold is heated by means of heaters 2, 5 up to the solidification temp. of Cu alloy or above, so that solidification of the molten metal 3 is not complete in the mold 1 and, as a result, drawing incapability due to the friction between the mold and the continuously cast billet can be prevented at the time of drawing the continuously cast billet. After that, the continuously cast billet is bold-worked or warm-worked at >=50% draft to undergo strength improvement and is then heated at 350-700 deg.C to undergo sufficient age precipitation, so that electric conductivity can be satisfactorily recovered.

Title: Control mechanism for decentralized shared memory reducing communication frequency
Inventor: NAKAYAMA TAIICHI
IPC: G06F9/52
Filed: 1994-04-06
Abstract: PURPOSE:To keep the consistensy of data and to reduce the communication frequency by carrying out at one time the reflection of the writing to a reproduction onto a memory substance and the deletion of the reproduction that is notified as the invalid one from a server. CONSTITUTION:A computer 2 gives a request 9 to a server 1 only when it tries to perform an operation 8 to read a reproduction 5 that is rewritten by the computer 2 itself and reflects the writing operations so far done to the reproduction 5 onto the substance of a shared memory 4. The server 1 returns its answer 10 to the computer 2 before a reproduction 6 of the corresponding memory of another computer 3 is invalidated. When the server 1 receives some communication other than the operation request given to the corresponding memory 4 from the computer 3 after communications 9 and 10, the server 1 notifies the memory 4 of the invalidation of the reproduction 6 concurrently with its answer. Therefore a control mechanism delays the communications as long as possible and processes them at a time. Thus the communication frequency can be reduced and the consistency of data can be strictly kept.

Following this, the phase of the voltage of a backup power source 2 is converted by means of a phase converter 11 from a bus-bar 6 immediately, and the voltage is supplied to the auxiliary machine 8 by closing a bus-bar connecting circuit-breaker 12. The phase converter 11 has a transformer ratio of 1 to 1, and its primary and secondary windings are Y-and DELTA-connected respectively. And the phase converter 11 delays the voltage phase of the backup power source by 30 deg.. As a result, it becomes possible to lighten the influence on other apparatuses at the time of changing power sources.

Filed: 1985-05-14
Abstract: PURPOSE:To control a voltage with excellent responsiveness even if the frequency of a magneto generator alters by comparing a voltage integrated from a voltage of an AC output terminal with a reference voltage to control a phase controller. CONSTITUTION:The phase voltage of a magneto generator, i.e., the voltages of AC output terminals 1a-1c are output through a full-wave rectifying mixing bridge 23 having a diode 3 and a phase controller 2. A phase controller 4 integrates voltages of AC output terminals 1a-1c in a synchronous integrator 5, compares by a comparator 6 the integrated voltage signal with a reference voltage, and applies a control signal to the gate circuit 7 of the controller 2. Thus, even when the rotating speed remarkably varies, the rectified DC output voltage can be controlled in the prescribed wide dynamic range.

Title: Data transmission control system
Inventor: NAKAMURA YASUO
IPC: H04L12/417
Filed: 1984-05-21
Abstract: PURPOSE:To improve the communication efficiency of a network by allowing a transmitter (node) participating newly in the network to recognize immediately the system constitution of the network without needing a special monitor node. CONSTITUTION:When a power supply is applied to a node c4, the node c4 awaits at first the circulation of the communication right (token). When a communication right transfer instruction (token) is detected in an FC41 in the received communication network, after a new participation notice instruction (SNN instruction) is transmitted to all nodes in the network, the token is transmitted to a downstream node (node b3), the transmission right is transferred to await the transmission of the network constitution instruction (SCONF instruction) from the node b3. When the toke is a token from a newly participating node, the node b3 transmits the SCONF instruction to a new node (node c4). Since the network constitution information (TBL) stored in the node b3 is added to a data area 44 of the SCONF instruction, the node c4 stores the content of the area 44 of the received SCONF instruction in a TBL in the RAM16 of the own node.

When the processor 12 has the shortage of resources, the transmission of data is held by the processor 11 as if the processor 11 has no shortage of resources. When the processor 11 has the shortage of resources, data are sent to the processor 13 having no shortage of resources and held there. Then the data are sent to the processor 12 via a route 16 as soon as the shortage of resources of the processor 12 is solved.
