Abstract: The dynamic DC offset canceling apparatus includes: section 104 that detects dynamic DC offset in longest overlapping part sequences from the differences between the sampling values of a first longest overlapping part sequence and the sampling values of a second longest overlapping part sequence, the first longest overlapping part sequence and the second longest overlapping part sequence being overlapping part sequences in a training sequence of the received signal; section 105 that detects dynamic DC offset outside the longest overlapping part sequences from the difference between an average value of sampling values of a received signal which exists in a burst before the first longest overlapping part sequence, and an average value of sampling values of a received signal which exists in a burst after the second longest overlapping part sequence; and section 106 that adaptively subtracts a DC offset value from the received signal based on these results.

Abstract: An electric pump may comprise a pump case (110, 150) having a pump chamber. An impeller 143 may be rotatably disposed within the pump chamber. The impeller 143 may include a magnetized cylindrical portion 145. A stator 133 may be disposed opposite to the cylindrical portion 145 of the impeller 143. The stator 133 may drive the impeller 143 by applying magnetic forces to the cylindrical portion 145 of the impeller 143. A shaft 146 may be formed integrally with the impeller 143. One end of the shaft 143 may be rotatably supported with respect to the pump case.

Abstract: The present invention teaches a method for surface treating an engine valve made from titanium or titanium alloy in order to form a hardened coating having a high level of adhesion to the surface of the engine valve, and also having improved abrasion and impact resistances. The method includes a hardening treatment process for forming a hardened layer on the surface of the engine valve by providing oxygen dissolved into the surface of the engine valve as a solid solution; and a coating treatment process applied after the hardening treatment process. The coating treatment process forms a coating on the surface of the engine valve by physical vapor deposition.

Abstract: A cell-preservation liquid containing at least a saccharide, sodium ion, and potassium ion, which is characterized in that the molar concentration of the contained sodium ion is equal to or more than that of the potassium ion is provided. The preservation liquid enables not only cryopreservation but also cold preservation, and an easy cell-preservation method may be provided. Moreover, when the cell-preservation liquid of the present invention is used, cell culture may be performed by inoculating cells in a medium with the cells suspended in the preservation liquid without a washing step or the like, so that the cells may be easily cultured.

Abstract: With attention focused on the most significant bit (sign indicating positive or negative) of a soft decision value, the present invention provides a method of deciding whether iterations of soft decision decoding of turbo decoding should be terminated or not. A change of a positive/negative bit value included in a soft decision result for each bit of a received codeword is monitored. When the values of the positive/negative bits cease to fluctuate and such a tendency is observed for almost all bits of the received codeword, it is decided that the positive/negative bits have converged. Termination of iterations of soft decision decoding is determined based on the decision result.
