Abstract:
Filter circuit includes Nth-order active filters switching circuit which switches shorting or non-shorting of active filter, and power-supply control circuit which controls such that a power supply of active filter is turned off when switching circuit shorts active filter. A receiver employing filter circuit turns off the power supply of active filter not needed when no interference wave exists within a given range from a desired frequency band. The foregoing structure allows lowering the power consumption of filter circuit.
Abstract:
Switchmode DC-DC power converters using one or more non-Silicon-based switching transistors and a Silicon-based (e.g. CMOS) controller are disclosed. The non-Silicon-based switching transistors may comprise, but are not necessarily limited to, HI-V compound semiconductor devices such as gallium arsenide (GaAs) metal-semiconductor field effect transistors (MESFETs) or heterostructure FETs such as high electron mobility transistors (HEMTs). According to an embodiment of the invention, the low figure of merit (FoM), τFET, of the non-Silicon-based switching transistors allows the converters of the present invention to be employed in envelope tracking amplifier circuits of wireless devices designed for high-bandwidth technologies such as, for example, EDGE and UMTS, thereby improving the efficiency and battery saving capabilities of the wireless devices.
Abstract:
The magnitude of an amplitude waveform of an electromagnetic wave generated when irradiating a pulse laser beam to a structure A including diffusion regions provided in the structure of a semiconductor device to be inspected is compared with the magnitude of an amplitude waveform of an electromagnetic wave radiated when irradiating the pulse laser beam to a structure A of a reference device measured in advance, and the detection sensitivity of the electromagnetic wave is corrected (S14). Thereafter, measurement errors caused by variations in the detection sensitivity of electromagnetic waves of an inspecting apparatus are eliminated by inspecting the semiconductor device as an inspection target, so that the quality of the semiconductor device is precisely determined (S16).

A purpose of the present invention is to provide a diversity receiver and a diversity receiving method, which are capable of performing a diversity reception without depending upon a moving speed, and also capable of achieving compatibility between reception performance and current consumption. A bit error rate calculator (107) calculates a bit error rate from a demodulation result of a demodulator (106); a switching frequency calculator (108) calculates a switching frequency which corresponds to such a frequency for alternately switching initiating and stopping operations of the diversity reception in response to the bit error rate calculated by the bit error rate calculator (107); and a switching controller (105) performs a switching operation for selecting both two receivers (103, 104), and another switching operation for selecting any one of the two receivers (103, 104) in accordance with the switching frequency calculated by the switching frequency calculator (108) so as to synthesize respective output signals with each other to output a synthesized signal in a case where two sets of the receivers (103, 104) are selected.

Abstract:
Disclosed is a technique which reduces the packet loss and the band consumption for data transfer when a mobile terminal conducts the handover between a fixed base station and a mobile base station for group movement. According to this technique, when an MH (mobile terminal) 320 conducts the handover from a fixed base station (E-LSR 230) positioned at an edge of an access network 200 to a mobile base station (MEB 310) located in a train or the like, a predetermined flag is appended to a frame addressed to the MH in a label switching router (P-LSR 210) positioned at a core network 100 side edge of the access network. The frame having the appended flag is copied in the E-LSR 230. One frame after copied is transmitted directly from the E-LSR to the MH while the other frame after copied is transferred from the E-LSR to the MEB and then transmitted from the MEB to the MH, thus realizing the soft handover.

In a refrigeration cycle apparatus having an expansion mechanism, a method to swiftly generate a pressure difference upstream and downstream of the expansion mechanism of, thereby enhancing the starting performance of the refrigeration cycle apparatus The apparatus has a compression mechanism, a utilizing-side heat exchange, an expansion mechanism for recovering power, and a heat source-side heat exchanger. The revolution number of the heat source fluid transfer means is made smaller than a target revolution number or the heat source fluid transfer means is stopped during a predetermined time after the compression mechanism is started. When the compression mechanism is started, the pressure difference can be generated upstream and downstream of the expansion mechanism for a short time, the operation of the expansion mechanism does not become unstable, vibration and noise can be prevented, and the refrigeration cycle apparatus can swiftly be started.
Abstract:
A screen printing apparatus and a screen printing method facilitating to adjust a state of filling a paste. By adjusting a pneumatic pressure of pressing a squeezee 9a formed with a flexible region at at least a portion thereof to a surface of a mask 2, the squeezee 9a is moved up and down to follow recesses and projections of a surface of the mask 2 substantially in real time and an attack angle θ in sliding is maintained substantially constant. Thereby, a state of filling a paste can be stabilized without being influenced by recesses and projections of the surface of the mask 2 and promotion of a print quality can be expected. Further, bending is produced at the squeezee 9a by only adjusting the pneumatic pressure, and therefore, an attack angle θ in correspondence with a change in a print condition of a kind or a property of the paste, a thickness of the mask and the like can easily be changed.
Abstract:
A drive device includes a recording/reproducing unit and a drive control unit. The drive control unit compares the physical address corresponding to the logical address contained in the recording instruction to the next recording-enabled address. When the physical address corresponding to the logical address contained in the recording instruction is smaller than the next recording-enabled address, the drive control unit controls the recording/reproducing unit to record data at a particular position in the user data area which is other than the position indicated by the physical address corresponding to the logical address contained in the recording instruction. When the physical address corresponding to the logical address contained in the recording instruction is identical to the next recording-enabled address, the drive control unit controls the recording/reproducing unit to record data at a position indicated by the physical address corresponding to the logical address contained in the recording instruction.
