Patent CA-2016151-A1 (CA)
IPC: F16H61/02
Filed: 1990-05-07
Abstract: A countershaft-type transmission for use on an automobile has a plurality of parallel gear trains disposed on and between an input shaft and a countershaft, for trans-mitting power between the shafts, the gear trains including two high-load gear trains to which higher loads are imposed, and two one-way clutches disposed respectively in the two high-load gear trains, for allowing power from an engine to be transmitted only in a driving direction.  The two high-load gear trains are disposed one on each side of the bear-ings by which the shafts are rotatably supported.  Each of the one-way clutches has an input member and an output member, the output member of one of the one-way clutches being coupled to the input member of the other of the one-way clutches through a connector assembly which is disposed in a radially inner portion of one of the bearings.  The gear trains also include a third high-load gear train to which a higher load is imposed, the third high-load gear train being disposed near an end of the transmission.  A clutch for selecting the third high-load gear train is dis-posed on the countershaft.  A method of and an apparatus for controlling shifting operation of the transmission are also disclosed.

Title: Split instruction paging method and means

IPC: G06F12/02
Filed: 1992-03-02
Abstract: SPLIT INSTRUCTION PAGING METHOD AND MEANS                     ABSTRACT OF THE DISCLOSURE      Asynchronously transfers blocks of data (called pages) between two different electronic media of a data processing system.  The different media may be a system main storage and a system expanded storage or a non-volatile external type of storage,  either of which use different addressing than the main storage.  All of these storages may be made of DRAM or SRAM technology with battery backup when necessary. The invention splits the involvement of a program requesting a  page  transfer  into  a  pair  of  instructions  per  page transfer executing on one or more central processors.  The first instruction of a pair starts another processor that controls  the  asynchronous page  transfer,  and the  second instruction of the pair enables the communication of the end of the page transfer to the program.  Neither instruction in the pair interrupts the program for the page transfer.  A processor executing the starting instruction is immediately free to execute any other available instructions.  Although both  instructions  in  a  pair  may  be  executed  by  one processor, the pair may be executed by separate processors. And the execution of other instructions may overlap the page transfer between the execution of the pair.
