Abstract: A brushless direct current motor is energized by a power stage. Switches of the power stage are selectively switched by an electronic control device. In order to determine the correct commutation pattern, without using rotor position indicators such as Hall effect devices, the control device is arranged to sample the power fed to the motor. The samples, each responsive to a test signal or normal energization pulses received by the motor, in a ordered sequence define an analogue function whose parameters can be determined by mathematical analysis. The analysis applied to the samples derives the necessary commutation information and the energization signals in a rapid manner by employing a vector or complex number addition based on functions dependent on variable inductance in the operation of the motor.

Abstract: Surface stresses induced in zones of low mechanical resistance which are pressed radially inward during assembly may cause damage to an anticorrosion enamel coating on the housing of a vacuum brake booster. This can be largely prevented if zones of lower resistance are formed on one housing half (2) by two facing peripheral tongues (7, 8) which, in the assembled housing (1), engage axially behind an outturned rim (3) of the other housing half (1). The invention also relates to a process for manufacturing said housing.

Abstract: A method and system for accurately inspecting an electroconductive film using an eddy current and a process and apparatus for production of an optical fiber which measures on-line the electrical resistance, which shows the state of formation of the electroconductive hermetic coating of the optical fiber by the electroconductive film inspection method and reflects back the measurement results to the hermetic coating forming conditions are disclosed. Optical fiber is made up of a core, cladding, amorphous carbon film or other electroconductive hermetic coating formed on the outer surface of the cladding, and a protective coating. The electrical resistance of the hermetic coating generates an eddy current at the coating, the eddy current generated is detected, and the phase angle of the complex impedance is detected to enable calculation. In particular, to accurately detect the phase angle, the high frequency current for generating the eddy current is changes by a low frequency of about 1/100th of the high frequency to change the average intensity and obtain at least two points of measurement defining the above phase angle. The electrical resistance of the hermetic coating is calculated from this phase angle. The electrical resistance shows the state of formation of the hermetic coating. The measurement value of the electrical resistance of the hermetic coating is used for setting the hermetic coating production conditions. The electroconductive film inspection method of the present invention may also be used for quality control etc. of thin films. <IMAGE>

Date Feb. 21, 1991.Al base - Si hypereutetic alloys can exhibit problems of variable and unwanted microstructure throughout the section of the article being cast. This problem is overcome by controlled cooling of the mold in critical areas, to remove or prevent excessive accumulation of heat energy and avoid the formation of intense convection currents in still molten alloy. Consequently, the necessary coupled growth of the Al-Si eutectic is promoted and the resultant microstructure is substantially free of primary Si. The 3HA and modified 3HA alloys of the applicant are considered on the basis of their wear resistance and improved machineability for automotive applications, such as engine blocks and cylinder heads. A first feature of the controlled cooling procedure is supply of coolant to regions in the mold, above and extending from the gate, such that solidification progresses uniformly from the remote regions of the mold spaces towards the gate to give a substantially uniform microstructure throughout the casting. Various coolants may be used, so that temperature in the vicinity of the gate is 50 DEG -75 DEG  C. above those at the extremities. A second feature of the controlled cooling procedure consists of supplying melt to the mold cavity through a plurality of gates, spaced relative to one another in the critical control region of the mold. The result of using such a plurality of gates, is that the energy accumulated is more widely distributed in a plurality of critical control regions, in order to achieve the necessary temperatures at the remote and gate regions and temperature differentials between these.

Abstract: A filter useful as a cigarette smoke filter is made by convergingly passing a flat restrained meltblown web successively through a heated zone and a trumpet to form a roving. The roving may be processed to make filters. The process results in stretch orientation of longitudinal fibers and bulking due to cross fibers. Primary and secondary pleats formed in the web are bundled into a cylindrical roving. The pleats add bulking to the web and provide fluid permeability through the filter.
