Patent EP-0481125-A2 (EP)
Inventor: LOVETT DON
IPC: B06B1/02
Filed: 1990-12-14
Abstract: In a friction welding arrangement in which the driven vibratory unit carries a tool for accommodating a part to be joined, the drive is to be excited in such a way that the vibratory unit with the tool vibrates at the mechanical resonance frequency. In the case of different tools, the resonance frequency is also different. Matching is effected according to the invention by a microprocessor which changes the working frequency of the alternating current signal for exciting the drive until the current intensity of the alternating current signal is minimal at a predetermined amplitude of vibration. <IMAGE>

Abstract: A system and method for load sharing processing operations between a vehicle mounted station (105) and a stationary base station (25) having a large capacity host computer (18) is described. The vehicle mounted station (105) has detectors for determining operating conditions of a vehicle and controllers (3,4,501) for varying the operating conditions. The controllers (3,4,501) are connected to a transmitter-receiver (5) which is arranged to communicate over a path (10) with a transmitter-receiver (11) of the base station (25). The base station (25) has a host computer (18) having a large memory capacity. At predetermined intervals, for example, distance of travel or at engine stop, the vehicle transmitter (5) transmits operating conditions to the base receiver (11) for data processing and the base transmitter (11) then transmits processed data back to the receiver vehicle (5), whereupon the controllers (3, 4, 501) modify the vehicle operating conditons. The vehicle operating conditions may be an indication of life expectancy of fuel injectors or sensors, updating data processing maps. The presence of abnormal operating conditions may be detected by the vehicle mounted station (105), evaluated by the base station (25) and an emergency warning indication provided back to the vehicle mounted station (105), or if the abnormal condition is not of an emergency nature then counter measures are transmitted from the base station (25) to the vehicle mounted station (105).

Abstract: The present specification discloses a diagnosis system and an optimum control unit for an internal combustion engine. The basic concept of the present invention resides in that a random retrieved signal (ΔTi, ΔϑadvM) of which auto correlation function is an impulse shape is superposed on a signal of an internal combustion engine, said superposed signal is used to measure a change of an operation state of the internal combustion engine, and an optimum direction of a control value is detected by a correlation between said measured value and retrieved signal. This method includes the steps of superposing a search signal for fine adjusting a fuel flow quantity value and an ignition timing on a fuel flow quantity signal (Ti) and an ignition timing signal (ϑiq) respectively, applying the fuel flow quantity signal and the ignition timing signal superposed with said search signal respectively to the internal combustion engine, detecting a value of a parameter showing a revolution number (N) or an operation state of the internal combustion engine in response to the superposed signals, detecting a correlation between the detected value and the search signal, and carrying out diagnosis or control of the internal combustion engine based on the detected correlation.

Abstract: A laminated stator assembly for an electric motor includes plate laminations (10) which have square-trimmed edge segments (14) separated by circular peripheral edge sectors (13), which plates are randomly oriented in assembling the stator to provide a generally cylindrical outer surface. In this manner, the stator can be enclosed in and supported by an outer motor shell or housing which is substantially thinner and less expensive. The stator assembly of the present invention enjoys the material savings and enhanced air cooling characteristics of prior art stator constructions utilizing square-trimmed laminations, but eliminates the detrimental aspects of difficult alignment and heavier motor housings. In addition, overall stator assembly is substantially simplified.
