A method and apparatus for communicating between downhole tools without the necessity of routing the communication through a surface module. Communications sent by downhole tools are examined and extracted downhole. If the communications are intended for other downhole tools, the communications are copied to a downlink and send to a specific intended tool, a group of tools, or all the tools. This is all done downhole, significantly reducing the latency between command and response.

In the hand-held vacuum pump 1, the main body 1a of the vacuum pump in which the pump room 4a is formed and the electric motor 2 are connected via the shaft coupling 21. The main body of the vacuum pump has the driving shaft 10. One ball bearing 15b supporting the driving shaft is supported by the cylinder. The other ball bearing 15a is sup ported by the flange 5 mounted hermetically at the cylinder. The end part of the cylinder at the side of the electric motor accommodates the shaft coupling, and is engaged with the end part of the electric motor so that the electric motor may support the cylinder.

In screen printing for printing cream-like solder on a board 7 through through-holes of a mask plate 12, removal of the board 7 from a lower surface of the mask plate 12 is performed in such a manner that the board 7 is moved down at a first descending velocity V1 as a lower velocity during an initial stroke S1 of from a state where the removal of the board 7 starts to a state where the board 7 is removed from the mask plate 12 so that the distance between the upper surface of the board 7 and the lower surface of the mask plate 12 reaches a predetermined value set to be in a range of from a half to twice as large as the thickness of the mask plate 12, and that the board 7 is moved down at a second descending velocity V2 as a higher velocity after the initial stroke S1. Accordingly, even in the case where solder apt to vary according to the passage of time is used, good removability and stable print quality can be secured.

A circuit group control system which receives from a master processor a first command sequence and a second command sequence each of which is composed of a plurality of commands, each command being to be executed by one of a plurality of circuits, and causes any available circuits to execute the commands one by one in order of arrangement in each command sequence. The circuit group control system achieves concurrent execution of a plurality of command sequences by causing a circuit (a second circuit) to execute a command in the second command sequence while another circuit (a first circuit) is executing another command in the first command sequence.

A cell phone including a built-in antenna, the cell phone having a reduced physical size of an antenna element, a decreased weight and satisfying an impact resistance, and suppressing a variation in a dimension caused by mass production and considering an actual use state in which a hand or the like approaches. A dielectric between an antenna element and a ground is a support member of a cyclo-olefin polymer in a plating grade having an impact resistance which is obtained by blending styrene type rubber, polyolefin type rubber (elastomer) or both of them, and the antenna element is constituted by a plating formed on a main surface of the dielectric.

Processor and instruction conversion apparatus, including a technique for reducing the number of types of instructions and processor hardware scale when conditional instructions are used. The processor includes a stare hold unit, an obtaining unit, a decoding unit, a judging unit, and an execution unit. The judging unit judges whether a state hold unit renewal state is included in either of the state and the plurality of states specified by the first state condition in the first conditional instruction when decoded by the decoding unit. When the judgment is affirmative, the execution unit executes an operation specified by the operation code in the first conditional instruction decoded by the decoding unit. The instruction set is assigned first conditional instructions with a first state condition which is mutually exclusive with a second state condition for an unassigned second conditional instruction, both having the same operation code.

A borehole telemetry system including a surface telemetry module, a downhole telemetry module, and a multiplexed datalink between the surface and downhole modules capable of transferring data alternately between an uplink in which date is transferred from the downhole module to the surface module and a downlink in which data is transferred from the surface module to the downhole module; wherein the data link can be switched between a first configuration in which a relatively long time is assigned to the uplink and a relatively short time is assigned to the downlink, and a second configuration in which a relatively long time is assigned to the downlink and a relatively short time is assigned to the uplink. The first configuration can be used to transmit data when logging with downhole tools and the second configuration can be used to program logging tools.

The processor according to the present invention includes a flag register that stores a first flag group and a second flag group. The second flag group includes the same operation flags (a carry flag and an overflow flag) as the first flag group. The processor executes first-type instructions and second-type instructions. The first-type instruction instructs to perform an operation and to update the first flag group according to the result of the operation. The second-type instruction instructs to perform an operation different from the operation in the first-type instruction and updates the second flag group according to the result of the operation.
