Title: Generation of combination of rf and axial dc electric fields in an rf-only multipole
Inventor: KOVTOUN VIATCHESLAV V
IPC: H01J49/42
Filed: 2006-02-10
Granted: 2010-11-02
Abstract: An RF-only multipole includes a spiral resistive path formed around each multipole rod body. RF voltages are applied to the rod body and resistive path, and DC voltages are applied to the resistive path, to create a radially confining RF field and an axial DC field that assists in propelling ions through the multipole interior along the longitudinal axis thereof. In one implementation, the resistive path takes the form of a wire of resistive material, such as nichrome, which is laid down in the groove defined between threads formed on the rod body. The RF-only multipole of the invention avoids the need to use auxiliary rods or similar supplemental structures to generate the axial DC field.

Abstract: When stopping an operation of a fuel cell power plant, a controller (30) first stops fuel gas supply to an anode (2), then supplies a dry oxidant gas to a cathode (3) such that the output voltage of the fuel cell stack (1) decreases.    The controller (30) then connects a secondary battery (31) to the fuel cell stack (1) so as to consume an output power generated by a reaction of the residual fuel gas in the anode (2). After this processing, the controller (30) replaces the residual fuel gas in the anode (2) with dry oxidant gas, then maintains the fuel cell stack (1) in a closed state, thereby preventing local cell formation in the anode due to mixing of the residual fuel gas with oxidant gas, and hence preventing corrosion of a catalyst layer of the cathode (3) due to local cell corrosion.

Abstract: The present invention relates to a process and a device for utilization of waste heat from a high-temperature hood in the dryer section of a paper machine. Here, the waste heat from the high-temperature hood is applied to the waste steam and the condensate, respectively, from a steam system by means of a heat exchanger, thus improving utilization of the energy contained in the exhaust air from a high-temperature hood. Known heat recovery processes have the disadvantage that the condensate fed through the heat exchanger must always be measured such that the condensate is guaranteed to evaporate completely. The present invention provides an improved heat recovery process that is easier to regulate, because the condensate does not evaporate in the heat exchanger.

Abstract: Techniques for sending and receiving acknowledgement (ACK) information in a wireless communication system are described. A base station sends control information and data to a user equipment (UE) and receives ACK information from the UE. The base station performs detection for the ACK information based on (i) a first hypothesis for the control information being missed by the UE and (ii) a second hypothesis for the control information being received correctly by the UE. In one design, the ACK information may have a variable size, and the base station may perform detection for the ACK information based on different block codes for the first and second hypotheses. In another design, the ACK information may have a fixed size, and the base station may perform detection for the ACK information based on a single block code and obtain a fixed number of bits for the ACK information for both hypotheses.
