Title: File extension by clients in a distributed data processing system
Inventor: MORGAN STEPHEN P
IPC: G06F13/00
Filed: 1989-10-27
Granted: 1995-05-23
Abstract: The system and method of this invention controls how client data processing systems in a distributed networking environment can efficiently extend files and write into regions of the files previously unoccu-pied by data.  The server data processing system manages the distributed allocation of new file blocks by sending nascent zeros in addition to real bytes that have been requested by the client data processing system.  Nascent zeros are logically zero bytes that have never been stored to or written to, and may be outside the current extent of the file.  The server determines whether or not this additional range of nascent zeros will be sent to a client depending upon the amount of physical storage available at the server, and whether or not other client data process-ing systems require access to this range of blocks. Likewise, the client data processing system has the option of writing to this additional range of nascent zeros.  By writing to the additional range of nascent zeros, a client data processing system can minimize the network traffic overhead used in sending messages to the server data processing system requesting a range of bytes.

Title: Integrated circuit package and compact assemblies thereof
Inventor: TAI KING LIEN
IPC: H01L23/367
Filed: 1991-07-04
Granted: 1995-09-05
Abstract: An integrated circuit package comprises a thermally conductive plate for receiving an integrated circuit and an open rectangular structure of conductor and insulator for surrounding the sides of the circuit and presenting one or more linear arrays of conductive connectors extending laterally through the rectangular structure. Preferably the rectangular structure also includes transverse contacts. Advantageously the plate includes extensions beyond the rectangular structure for acting as cooling fins on opposing sides of the rectangular structure. The linear arrays and cooling fins are preferably on different pairs of parallel sides. The integrated circuit package permits the aggregation of packages into assemblies and into clusters of assemblies rich in interconnections. Vertically stacked packages form a rectangular parallelepiped having a plurality of parallel planar cooling fins projecting from two opposing surfaces and another pair of planar surfaces providing rectangular arrays of contacts to the enclosed integrated circuits. In addition, transverse contacts permit electrical interconnection of the stacked packages. Linear clusters can be aggregated as a linear array of such assemblies with their contact surfaces interconnected either directly by an anisotropically conducting plane or indirectly by an intervening transformation plane. In a preferred linear cluster, successive assemblies are rotated by 90° with respect to the axis of the array. In such clusters each package in the rotated assembly contacts each package in the neighboring assemblies. In low power equipment, elimination of the cooling fins permits even higher levels of interconnection such as rectangular clusters of assemblies.

Patent CA-2078937-C (CA)
Inventor: INADA TAKAHIRO
IPC: B25J9/06
Filed: 1992-09-23
Granted: 1996-03-26
Abstract: A wrist mechanism mounted on an arm of a robot has a wrist flange to which a spray gun is mounted.  Coaxially with  the  arm  are  provided  concentric  and  relatively rotatable cylinders.  From the outermost cylinder extends forward a housing in which gears and shafts are enclosed and operate as follows.   Rotations of second and third inner cylinders are transmitted via spur gear trains to respective  power  transmission  shafts  extending  in parallel to the axis of the cylinders.  Bevel gears fixed to respective far ends of the transmission shafts mesh with  other  bevel  gears  which  have  a  second  axis transverse to the axis of the cylinders.  A cylindrical member fixed to one of the other bevel gears is therefore swingable about the second axis.   Rotation of the other bevel gear is transmitted to a further gear to rotate the spray gun.   A cover besides the housing has an opening through which a flexible paint-supply hose is led into the mechanism to be connected to the spray gun.   This serves to reduce the length of the hose from a paint color changeover valve and hence shorten the rinsing time of the hose.   The second axis enables the spray gun to swing therearound,  thereby eliminating a dead space to which the spray gun cannot have access.
