Patent EP-0140582-A2 (EP)
Inventor: BURGUETTE MARIO DOMINGUEZ MINN
IPC: G11B5/702
Filed: 1984-09-27
Abstract: A magnetic recording medium protected by a very thin, composite low surface energy covering is disclosed. The covering comprises a primer layer of a polymerized phosphorylated monomer or oligomer and an outer lubricant layer of perfluoropolyether polymer. The two layers may be polymerized in situ. The primer layer is made from monomers such as phosphorylated bis[4-(methacryloyloxy- hydroxypropylcarbamato)-cyclohexyl]methane. The outer layer is made from a polymerizable perfluoropolyether monomer such asCH=CH<sub>2</sub>. The composite low surface energy covering is especially useful for providing lubricity and corrosion resistance to a metallic thin-film magnetic recording coating.

Abstract: @ An ignition timing control system for an internal combustion engine (18) varies the timing of a magneto (14) in accordance with a pre-programmed ignition advance schedule. An optical pick-up (22) senses the passage of slots (26) in a disc (24) which is rotated at the speed of a distributor (16) and produces constant angular width reference pulses corresponding to fixed ignition timing in the engine's cylinders (13). A magnetic pick-up (36) detects incremental rotation of the engine's crankshaft (33) and produces timing control signals proportional to engine speed. The timing control signals and reference pulses are converted to a multi-bit data word which is used to synthesize an analog control function representing variable ignition timing using a pre- programmed digital to analog converter (58). A speed controlled switch (70) gates ignition trigger signals corresponding to the fixed timing of the reference pulses when engine speed is below a pre-selected value but gates ignition trigger signals corresponding to the variable ignition timing of the pre-programmed ignition advance schedule when engine speed exceeds the pre-selected value.

Abstract: A load-commutated inverter for operating a synchronous motor (15) having two sets of 3-phase windings. The difference of phase angles between the two sets of the 3-phase windings is 30 degrees. The load-commutated inverter is provided with two sets of inverters and a control circuit (21, 25, 26). Each of the inverters (141, 142), is formed of thyristors. The inverters (141, 142) are coupled respectively to the 3-phase windings of the motor (15). The commutation of each of the thyristors is controlled in accordance with a given advanced control angle (B). The control circuit (21, 25, 26) is coupled to the inverters (141,142) and is responsive to a commutation overlapping angle (u) of currents (e.g., IU1, IV1 in Fig. 4A) supplied from the inverters (141, 142) to the 3-phase windings of the motor (15). The control circuit (21; 25, 26) adjusts the given advanced control angle (ß) so as to retain a relation:  
u + γ* ≤ 30 degrees wherein u denotes the commutation overlapping angle and γ* corresponds to the reverse-biasing time applied to each of the thyristors.

Abstract: In producing a SiC base sintered material containing a small amount of B as a sintering assistant, a boron-containing organic compound obtained by reaction between a boron compound and an uncross-linked phenolic resin, either a resol or a novolac, is used instead of using an elemental boron powder. The starting boron compound is, e.g., H 3 BO 3 , BCI 3  or (C 2 H 5 ) 2 BOH. A mixture comprising 100 parts by weight of SiC powder and 2-10 parts by weight of the boron-containing organic compound is compacted or molded into a desired shape, and the shaped material is heated in a nonoxidizing atmosphere first at a relatively low temperature to accomplish thermal decomposition of the boron-containing compound and then at a sufficiently high temperature such as 1800-2200°C to accomplish sintering of SiC. By this method agglomeration of boron in the sintered material is prevented, so that sound sintering is achieved in every region of the shaped material. Accordingly the products of this method are high in reliability as to mechanical strength.

Abstract: The invention relates to an impact-flaring plug for anchorage in a blind hole with a countersink. The plug consists of a tubular, slotted flaring anchor with an internal thread for securing objects, and an internal hole which tapers in the region of the slots, for insertion of the flaring anchor. A flaring pin, seated on the base of the hole, and with a cylindrical section originating from the insertion end and a tapering flaring cone connected thereto, can be driven into this section of the flaring anchor. For reasons of more simple manufacture and in order to prevent premature flaring when driving in the impact- flaring plug, the flaring pin is connected by means of its end face on the cone side to the end face of the flaring anchor, as one piece. Furthermore, the tapering internal hole of the flaring anchor terminates in the flaring pin. <IMAGE>
