Patent EP-0254310-A2 (EP)
Inventor: KIYOKAZU OKAMOTO C O NEC CORPO
IPC: H02P21/06
Filed: 1987-07-23
Abstract: An induction motor control apparatus includes a detector, a memory, a correction current generator, and a primary current correction circuit. The detector detects a rotational position of a rotary magnetic flux generated by a multi-phase primary current applied to a primary winding of an induction motor. The memory stores correction values corresponding to measured values of torque ripples periodically generated in correspondence with the rotational positions of the magnetic flux, receives an output from the detector for detecting the rotational position of the magnetic flux, and outputs one of the correction values stored in the memory in correspondence with the rotational position. The correction current generator generates a correction current by the correction value read out from the memory in correspondence with the rotational position of the magnetic flux. The primary current correction circuit corrects the primary current by the correction current.

Abstract: An instru­ment's process is controlled by a computer which has two concurrently defined tasks: an operator task for running an instrument control program, and a compiler task for compiling new instrument control programs input by the instrument's user. The currently running program is suspended and a new program's execution is begun when (a) a new program has been successfully compiled by the compiler, and (b) the current program is about to perform a jump back at the end of an instruction loop. When a main instrument control program finishes execut­ing, a new program is run if a new program has been successfully compiled; otherwise, execution of the most recently suspended program resumes. Thus a newly compiled program interrupts the currently running program only between instruction loops, and only as long as necessary to execute its instructions. If the newly compiled program merely resets a parameter, this inter­ruption is generally so short as to be unnoticeable. If, on the other hand, the newly compiled program is designed to control the instrument's process for a period of time, the new program takes control until it finishes execution. Thus the instrument's user is provided not only with the feel of being able to reset parameter values on the fly, but also with a flexible tool for revising an instrument control program on the fly.

Abstract: The pipelined slave protocol of the present invention eliminates the communication overhead between a CPU and a Floating Point co-processor for most floating point instructions by pipelining their execution beyond the CPU execution unit. Recovery mechanisms for CPU status information are implemented within the CPU to maintain precise floating point exceptions. As a result, the CPU can support very high floating point performance. The protocol also provides for overlapped execution of floating point and integer instructions by retaining the contents of those CPU registers which will be modified by the execution of an integer instruction.

Abstract: An injection moulded plastics article is produced by introducing a stream of molten plastics material from an injection moulding machine cylinder into an article forming mould space (13). Pressurised gas is supplied into the interior of the molten plastics material to form a gas containing cavity (25) therein. The plastics material is then allowed to solidify and cool sufficiently so that the article can itself sustain the form dictated by the mould surface. The cavity is vented to reduce the pressure within the cavity to ambient pressure prior to opening of the mould. The step of venting the cavity is achieved by providing at at least one position which is separate from the plastics inlet and the gas inlet a vent passage (30) in the mould open at its inner end to a part of the interior of the mould at which the gas containing cavity (25) is formed, and a retractable closure (31) for opening and closing the vent passage at its inner end, maintaining the closure in its closed position during the forming of the article whereby the cavity wall is formed over the inner end of the vent passage and the closure therefor, and subsequently retracting the closure to allow the creation of a vent opening in the cavity wall in the area of the inner end of the vent passage through which vent opening gas from the cavity passes into the vent passage. Apparatus for carrying out the above process is also described.
