Abstract: A process for improving properties of a synthetic resin powder which comprises: 
subjecting a latex of a graft-copolymer whose back bone is a rubber to coagulation, and adding a lubricant to the graft-copolymer in an amount of 0.01 to 10 parts by weight based on 100 parts by weight of said graft-­copolymer. According to the present invention, the bulk specific gravity of a synthetic resin powder can be made large, the flowability and blocking resistance can be remarkably improved in comparison with known methods. Accordingly, the blocking during storage can be prevented, a line for transport is not packed with the resin powder, it is possible to automatically weigh the resin powder, and it is applicable to the tendency to grow larger in transport.

Abstract: In known fan shroud designs, a secondary air flow, characterised by a parasitic return flow, takes place in the fan housing, and leads to power losses. The invention is intended to achieve, in particular, a noise reduction. It is proposed to match the shape of the fan shroud 8 to the main air flow 13, as a result of which the origination of a secondary flow is suppressed. A fan shroud 8 designed in such a manner has a first cylindrical wall part 17 which is matched to the diameter DM of the electrical machine 2 and to which a truncated conical wall part 16 connects. A second cylindrical wall part 18 can be connected thereto, which is covered on the end side with an air inlet grid 12. The arrangement is intended for cooling sealed electrical machines. Figure 2 is significant. <IMAGE>

IPC: H02J9/06
Filed: 1988-10-13
Abstract: An asynchronous multiphase switching method and apparatus are disclosed which transfers a system load between two asynchronous AC power sources in an im­proved manner. It operates as a make-before-break switch to provide uninterrupted power to the system load during the transfer while minimizing voltage and current fluctuations. The control circuitry allows energy to be supplied to the load during the transition without allowing current to flow between the power sources. A matrix of SCRs is used to transfer the load between the two power sources. The switches to be gated are determined by the relative timing re­lationships of the existing and takeover voltage waveforms. By altering the pattern of the switches which are gated and by controlling the direction of energy flow, the transition can be made between the power sources without interruption of power.

Abstract: A servo head control apparatus is controlled by driving a voice coil actuator located in a disk drive apparatus to position a head on a specific track of a disk and outputting a position signal indicating a position of the head relative to the disk. Based on the position signal, a track pulse signal is output for each track of a disk that is passed by the head. Based on the position signal, a velocity signal corresponding to seeking velocity of the head relative to the disk is output. Based on the track pulse signal, the distance to a target track from the present position of the head is calculated. A pre-set limit value and the calculated target distance of the head are calculated, the pre-set limit value being less than the target track position. A target velocity signal corresponding to the target distance is generated, this generation being performed at a pre-determined value when the calculated target distance is greater than the pre-set limit and being performed at a velocity profile value when the calculated target distance is smaller than the pre-set limit. A performance factor based on the acceleration of the head is generated and the target velocity signal is altered based on the performance factor. The voice coil actuator is then driven based on the target velocity signal.

Abstract: In a fast diode whose reverse voltage is equal to the bulk breakdown voltage, the object is to provide a peripheral termination which is simple to produce. This object is achieved by bringing about either a compensation of the doping concentration by gold diffusion or some other reduction in the effective doping concentration in a region near the surface of a lightly doped n-type layer, as a result of which there is a resultant lateral extension of the space charge zone and consequently, field strength overshoots at the p-n junction are avoided. As a result, the p-n junction can be passivated at the surface by simple planar means without additional measures such as, for example, providing field rings. Diodes in accordance with the invention find application mainly as protective diodes for power semiconductor devices which have to be switched off. <IMAGE>
