Title: Decentralized data processing system of modular construction
IPC: G06F15/177
Filed: 1981-12-09
Abstract: The system consists of any desired number of independent computer modules (2) with equal priority and independent periphery modules (3) with equal priority, wherein a processor (5) with a local bus and store is contained in each module (2, 3). The computer modules (2) which can work out user and service programs independently by interpreting at least one program language and the periphery modules (3) which can execute independently input-output instructions, or instruction chains are operated together with a general store (4) on common asynchronous bus (1). Operations are divided between the modules (2, 3) so that each module (2, 3) contains only that instruction which it needs to fulfil its special function. Tasks which one module (2, 3) cannot perform itself are passed on via the bus, to a module (2, 3) which is specialized for the purpose. Thus both in the hardware construction and in the operating system, a modular data processing system is afforded which can be extended as desired without alteration or adaptation of the operating system. <IMAGE>

Title: Transmission control method and transmission control device providing snappy downshifting
Inventor: ITO HIROSHI
IPC: F16H61/04
Filed: 1983-02-25
Abstract: A method is described for controlling a vehicle transmission mechanism which incorporates several selectively engageable power transmission systems each being selectively individually connectable between a first member and a second member for transmitting rotational power between them, with each such power transmission system including a clutching mechanism 4, 9 which can be selectively controlled either to freewheel in both rotational directions or to provide direct transmission of rotational power in one rotational direction only and to freewheel in the other rotational direction. While a first one of the power transmission systems which is for providing a certain speed stage is connected between the first member and the second member for transmitting rotational power between them at a gearing ratio appropriate to that certain speed stage, a second one of the power transmission systems which is for providing the speed stage one lower than that certain speed stage is also individually connected in parallel with the first power transmission system, with the particular clutching mechanism associated with the second power transmission system being controlled to be able to provide direct transmission of rotational power in one rotational direction only and to freewheel in the other rotational direction. Thus, the clutching mechanism of the second power transmission system freewheels. When a downshift is required, the clutching mechanism of the first power transmission system is disengaged, and the second power transmission system takes over the power transmission. A device employing a microcomputer 150 for practicing this method is also described. <IMAGE>
