Abstract: A rotary ring (1) for spinning comprising a holder (11), a ring-shaped rotary member (13) capable of rotating through a bearing (12) against the holder, a braking shoe (25) fixed to a lower end of the ring-shaped rotary member (13) and a braking runner (70) arranged between the holder (11) and the braking shoe (25). 
     Although the braking operation for the ring-shaped rotary member (13) is directly applied by raising a lower end (56) of the braking shoe due to a centrifugal force, in the conventional rotary ring, the present invention provides an indirect braking mechanism using the braking runner (70), whereby the rotary ring (1) can be used at a high rotational speed of the spindle and the ring-shaped rotary member (13) and in a broad range thereof, to manufacture a thread having a high quality.

Abstract: An integrated circuit FM detector (100) which compensates for variations in semiconductor manufacturing process and temperature comprises a pair of serially connected switched capacitor-operational amplifier combinations (101,103). The first combination (101) is a frequency-to-voltage converter and comprises a switched capacitor circuit (10,12) clocked at the frequency of the input signal (PH1), an operational amplifier (124) and a feedback resistor (127). The second combination (103) is a compensation circuit and comprises an input resistor (147-155), a feedback switched capacitor circuit (14) and an operational amplifier (177). The feedback switched capacitor circuit (14) is clocked at a fixed rate. Reversal of the roles of the resistor and the switched capacitor in the first and second combinations compensates for both temperature and manufacturing process variations. Electrical separation of the input and feedback switched capacitor circuits ensures against generation of unwanted noise in the form of beat frequencies, which could be generated if the switched capacitor circuits were used as the input and feedback circuits of a single operational amplifier.

Abstract: Process for pore formation in mortar by admixing a powder of a substance such as aluminium, silicon, calcium carbide which forms a gas upon chemical reaction with another mortar component. In order to avoid that the gas formation begins immediately after mixing the mortar, the particles of the gas-forming powder are provided, according to the invention, with a deactivating surface film. If these substances are metals forming a suitable resistant oxide film, the protective film can be prepared by oxidation, for example in the case of aluminium- or silicon-containing powders. Instead it is also possible to apply an oil, grease, resin or wax film which, after being mixed in the mortar, is degraded by chemical or physical processes, in particular hydrolysed. Such a film can also be used for retaining the previously formed deactivating oxide film without change and for ensuring in this manner the delay period previously established by the thickness of the oxide film formed, even after an extended storage period.

Abstract: 5n7 Control circuits for operating a two-phase brushless dc motor from a dc power source are described. Control of the motor is optimized by detecting induced back EMF of the two phases to sense rotor phase position. It is common knowledge that the voltage developed across the terminals of a permanent magnet motor can be represented by a winding resistance, a winding inductance and a generated back EMF. In two-phase brushless dc and permanent magnet stepping motors, the induced back EMFs of the two phases are displaced from each other by 90 electrical degrees. Thus, by detecting the back EMFs of the two phases, an accurate relative position of rotor-to-stator can be determined at any rotor position. Commutation of the motor phases and closed loop control of the motor and load is achieved by accurately sensing the back EMFs of the two phases. Also, phase position of the permanent magnet rotor poles is detected by integrating the sensed back EMFs of the two phases to produce quadrature sinewaves the magnitudes of which are constant relative to rotor speed.
