Title: Piston pump for low temperature liquid
Inventor: DROUVOT PHILIPPE
IPC: F04B15/08
Filed: 2011-06-21
Abstract: PROBLEM TO BE SOLVED: To provide a piston pump for a low temperature liquid, which is designed for a high working pressure.SOLUTION: A pump piston having a truncated conical piston top end is used. A valve head has an exit opening and a cavity corresponding to the piston top end. A discharge valve is arranged adjoining to the exit opening and intruding into a cylinder head. The piston top end is configured to penetrate the cavity region when the piston pump stroke is at the maximum. Since the piston top end is shaped to tightly fit the cavity of the valve head and completely intrudes the cavity region at the maximum piston stroke, a low temperature medium is always mechanically and completely eliminated from the valve head in each piston pump stroke. Further, since the discharge valve is arranged directly adjoining to the exit opening of the valve head and intruding into a sealed pressure pipe, no cavity is left in the pump working chamber where the low temperature medium can remain, and thereby, functional disorders due to a residual medium can be significantly decreased.

Title: Radar device and interference wave removing method
Inventor: MURANO TAKASHI
IPC: G01S13/95
Filed: 2011-07-05
Abstract: PROBLEM TO BE SOLVED: To remove influence due to an interference wave and to reduce side lobes when a pulse is compressed.SOLUTION: An IQ wave detecting section 171 performs quadrature detection of a received signal and obtains IQ data. An interference wave removing section 172 removes influence of an interference wave from the IQ data. In an interference wave removing process, a power value of a target range obtained by the same hit is corrected based on power values of ranges that surround the target range and data correction is performed such that a phase change among ranges obtained by the same hit is maintained. In a received signal of a transmitted pulse to which phase modulation or frequency modulation is applied, when applying demodulation thereto, a pulse compressing section 173 performs a process of converting the transmitted pulse to a pulse with a width less than that of the transmitted pulse by performing autocorrelation with a modulated transmission wave. In this case, since a phase state is maintained in the interference wave removing process, an occurrence of a side lobe in an output after a pulse is compressed can be suppressed.

IPC: F02M45/04
Filed: 2011-07-25
Abstract: PROBLEM TO BE SOLVED: To provide a fuel injection control device of an internal combustion engine achieving compatibility between a reduction in noises and NOx and a reduction in PM contained in discharge air.SOLUTION: The pressure of a fuel supplied to an injector 12 in pilot injection is set to be lower than the pressure of the fuel supplied to the injector 12 in main injection. Thus, the fuel jetted from the injector 12 in the pilot injection generates a thick mixture around the injector 12. Therefore, the ignitability of the fuel is improved even with a small amount of the pilot injection. On the other hand, in the main injection and after injection, the injector 12 jets the fuel at a pressure higher than that in the pilot injection. Therefore, the atomized fuel is supplied to a combustion chamber 18 that becomes high in pressure by the combustion of the fuel, and the combustion of the fuel is uniformized. Thus, the reduction in the noises and NOx and the reduction in the PM contained in the discharge air in the main injection and the after injection are achieved.
