Title: Radio receiver and gps receiver
Inventor: AIZAWA SUNAO
IPC: H04B17/00
Filed: 2003-06-27
Abstract: <P>PROBLEM TO BE SOLVED: To provide a radio receiver and a GPS receiver for enhancing positioning accuracy by surely determining an influence of a multipath of received radio waves from GPS satellites.  <P>SOLUTION: This receiver is structured so that signal processing parts 15a to 15n severally demodulate received signals from the plurality of GPS satellites by an output from a high-frequency wave reception part 14 to find information signal data from the respective GPS satellites included in the respective received signals and the levels of the respective received signals. A multipath determining/processing part 16 finds level differences between each of received signals of the processing parts 15a to 15n when using a dextrorotatory-circular-polarization antenna 11 and each of corresponding received signals when using a linear-polarization antenna 12. The degree of effect of the multipath on the received radiowave is thereby determined and the determination result is used to select a GPS satellite, a radio wave received from which is less affected by the multipath. A positioning calculation part 18 calculates a present position based on information signal data acquired based on the received radio wave of the selected GPS satellite.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Title: Power supply
Inventor: SATO MAKOTO
IPC: H02P27/06
Filed: 2003-06-30
Abstract: <P>PROBLEM TO BE SOLVED: To eliminate occurrence of rush currents at re-start of switching by discouraging that switching of an active filter stops due to fluctuation of a load, in a power supply comprising the active filter.  <P>SOLUTION: An AC power source 1 is converted to a DC voltage by a rectifier circuit 2 which is made into a prescribed DC voltage with an active filter 3. The prescribed DC voltage is smoothed by a smoothing capacitor 4 which is applied to a load 5. A control circuit 11 detects the temperature around the load 5 using a detection signal from an ambient air temperature detection circuit 10 in advance. If the detected ambient temperature is equal to or higher than a prescribed value, the target value of the active filter 3 is set to be higher than an normal one since load fluctuation is large. Thus, an output DC voltage does not exceed a target value, not stopping control of the active filter.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

IPC: G06F9/44
Filed: 2003-06-06
Abstract: <P>PROBLEM TO BE SOLVED: To provide a tracing module for generating tracing elements in tracing components included in a data processor.  <P>SOLUTION: The tracing module includes a trace generation unit which generates a plurality of tracing elements indicating a change according to reception of an input signal indicating the change of an architecture state subset from one or a plurality of components of the data processor and enables a receiver of the tracing elements to reconstruct the architecture state subset later and a table which is managed by the trace generation unit, which identifies architecture states from the previously generated tracing elements. Since the trace generation unit can decide whether or not the change of the architecture state can be derived by the receiver by referring to the table, only tracing elements regarding the change of the architecture states which can not be derived by the receiver can be generated.  <P>COPYRIGHT: (C)2004,JPO

Namely, a closed space defined by side walls, a top wall and a bottom wall is divided into a plurality of gas-liquid contact rooms by partition walls having openings which allow liquid to pass through their lower portions. A predetermined amount of liquid is maintained in each gas-liquid contact room, overflow walls are provided to keep clearances which allow liquid to pass through the intervals between the overflow walls and the partition walls. Further provided is a cylindrical gas-liquid jet flow generating apparatus having a liquid inlet, a mixed flow jetting outlet, a gas suction pipe and capable of jetting a gas-liquid mixed fluid by virtue of a negative pressure generated by a downward liquid swing current. The apparatus causes the liquid to move successively from the gas-liquid contact room on one side to another gas-liquid contact room on the other. Meanwhile, in each gas-liquid contact room, the liquid is taken from a liquid outlet and supplied to the jet flow generating apparatus from a liquid inlet so as to generate the negative pressure and thus suck the gas, thereby allowing each gas-liquid contact room to perform a gas-liquid contact which jets a mixed fluid from the jet opening.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To provide an internal combustion engine in which a temperature of a beveled part of a valve is lowered at a high load time, a temperature rise of an exhaust gas at a low temperature starting time is prevented from being delayed and an exhaust gas purifying catalyst can be rapidly activated in the internal combustion engine of high output.  <P>SOLUTION: This internal combustion engine includes a hollow valve containing a refrigerant 15 sealed in a hollow part 4 perforated from the beveled part 3a of an exhaust valve 3 to a stem 3b so that the beveled part 3a is disposed at a position above the stem 3b. In the state that the refrigerant is solidified by stopping in this internal combustion engine, the bevel part 3a side of the hollow part 4 becomes a hollow state, and a heat transfer of combustion gas by the refrigerant 5 when the internal combustion engine is started, is suppressed. Thus, the temperature rise of the exhaust gas at the low temperature starting time can be prevented from being delayed, and the exhaust gas purifying catalyst can be rapidly activated.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
