Abstract: The present invention provides a method for preparing azoxystrobin intermediates, comprising reacting compound A and dichloropyrimidine in the presence of a trimethylamine catalyst with the addition of a sodium methoxide solution in methanol or the addition of sodium methoxide and methanol separately to produce a mixture of compound B and compound C. Azoxystrobin intermediate compound B and compound C are synthesized from compound A in the present invention, which is catalyzed by using a trimethylamine catalyst, allowing the reaction to have high efficiency and high yield. In addition, the trimethylamine catalyst has a low boiling point and thus can be easily recycled so that the ammoniacal nitrogen content in wastewater can be reduced, and the difficulties and high costs for wastewater processing can be also reduced. The recycled trimethylamine catalyst can be reused in preparing intermediate compound B, which also has a high catalytic effect and can also achieve a high product yield.

Abstract: A compact and reliable changeable negative voltage transmission circuit is described. It is very useful for applications need passing changeable negative voltage to selected pins in certain mode. The changeable negative voltage is 0V when enable signal EN is low and ?V1 when enable signal EN is high. The circuit includes a control circuit and an output circuit. The control circuit includes a control high power source VDD and a control low power source VNEG.

Abstract: Replication techniques for file-based replication. A first file pool and a second pool may be created, respectively, on a first site and a second site. Storage for the first file pool may be provisioned from a first storage device group configured as a first consistency group. Storage for the second file pool may be provisioned from a second storage device group configured as a second consistency group. Modification operations, such as writes, may be applied to the first file pool. The modifications performed on the first file pool result in corresponding modifications to the first consistency group. The modifications may be replicated on the second file pool by applying the modifications to the second consistency group. File systems created in the first and second file pools may be self-contained and modifications applied to the first and second consistency groups may be applied in a specified order to ensure write consistency.

Abstract: A method for manufacturing a TAMR (thermal assisted magnetic recording) write head. The write head has a metal blocker formed against a distal end of a waveguide. The waveguide focuses optical radiation on an adjacent plasmon generator where it excites plasmon modes that heat the recording medium. Although the plasmon generator typically heats the recording medium using the plasmon near field to supply the required Joule heating, an unblocked waveguide would also send optical radiation to the medium and surrounding structures producing unwanted heating and device unreliability. The role of the blocker is to block the unwanted optical radiation and, thereby, to limit the heating to that supplied by the plasmon near field.

The coils are wound around a coil former, and the stator core is assembled to the coils. The pump body is a shell formed by surrounding a contour of the coils, the coil former, and the stator core which have been assembled to perform an integrated injection molding. The shell defines a magnetic core accommodating space used for accommodating the magnetic core and having an opening at a top portion. The magnetic core accommodating space extends from the opening to a center of the pump body. A supporting member is arranged in the opening at the top portion of the magnetic core accommodating space for supporting a bearing of the rotating shaft.

Abstract: A method and system for controlling discontinuous reception (DRX) in a mobile device in a wireless communications network uses autonomous DRX control after initial VoIP traffic setup. If the mobile device transmits a negative-acknowledgement signal (NACK) indicating unsuccessful receipt of a VoIP packet, then it autonomously turns on a predetermined delay time later to receive the retransmission of the VoIP packet. The predetermined delay time is related to the time for the base station to process the NACK and prepare the VoIP packet for retransmission. When the mobile device transmits or retransmits a VoIP packet, reception is deactivated, but is autonomously activated the predetermined delay time later to receive an acknowledgement signal (ACK) or NACK. VoIP packets may be transmitted from the mobile device the predetermined delay time before VoIP packets are transmitted from the base station.
