The magnetic layer comprising compounds (I) and (II) may also include an aliphatic acid having from 10-30 carbon atoms.
摘要:
A battery pack (21A) according to embodiments of the present invention comprises a plurality of battery modules (11A-11D) connected to each other in either one or both of a series connection mode and a parallel connection mode. An identifying information setting section (25) sets identifying information on each of the plurality of battery elements (11A-11D). A connection mode managing section (47) manages the connection mode between the plurality of battery elements (11A-11D) by using the identifying information set by the identifying information setting section (25). The identifying information on each of the plurality of battery elements (11A-11D) is made up of a combination of first identifying information on the potential of the one of the plurality of battery elements (11A-11D) and second identifying information on the battery pack (21A) serving as a superordinate battery element to which the one of the plurality of battery elements (11A-11D) belongs.
摘要:
In a radio receiving apparatus, an analog received signal is converted into a digital received signal. An unwanted wave in an adjacent channel band is rejected, that is adjacent to a passband for the digital received signal. The digital received signal with no unwanted wave is converted into a first demodulated signal. The first demodulated signal is converted into a second demodulated signal in analog form. A noise component is extracted from the first demodulated signal. The second demodulated signal is suppressed under squelch control when a squelch voltage that is a voltage of the noise component after rectification and smoothing becomes equal to or higher than a predetermined threshold level.
摘要:
A storage battery system in which multiple storage battery modules are connected in series and such that deteriorated storage battery modules may be made replaceable without causing dielectric breakdown. The storage battery system is one that has multiple storage battery modules connected in series and has a mechanism of, when the storage battery module is detached, disconnecting power source line connected to the storage battery modules after disconnecting communication line connected to the storage battery modules.

A negative electrode active material for a lithium ion secondary battery contains a lithium titanium complex oxide having a composition expressed as Li4Ti5-x-yFexVyO12 (where 0≦x≦0.3, 0≦y≦0.05) or Li4Ti5-x-zFexBzO12 (where 0≦x≦0.3, 0≦z≦0.3).
摘要:
A pre-acquired reference image, a currently picked-up ultrasonic image, and position information indicating a relation between a position of the ultrasonic probe when the reference image was picked-up and a current position of the ultrasonic probe are displayed on a display portion as navigation information. Also, when the following diagnosis image is to be acquired, probe movement information, specifying a position or the like to which the ultrasonic probe has to be moved, is displayed on the display portion as the navigation information.

摘要:
An ultrasonic probe has a plurality of modules joined at least along the elevation direction. The module has a plurality of first piezoelectric transducers having a first width with respect to the elevation direction. The module has at least one second piezoelectric transducer having a second width narrower than the first width with respect to the elevation direction. The second piezoelectric transducer is arranged at the module ends with respect to the elevation direction. The module is arranged in such a manner that the second piezoelectric transducer faces the second piezoelectric transducer of the adjacent module.
摘要:
A technique that makes it possible to suppress a crystal defect produced in an active area and thereby reduce the fraction defective of semiconductor devices is provided. A first embodiment relates to the planar configuration of SRAM. One of the features of the first embodiment is as illustrated in FIG. 4. That is, on the precondition that the active areas in n-channel MISFET formation regions are all configured in the isolated structure: the width of the terminal sections is made larger than the width of the central parts of the active areas. For example, the terminal sections are formed in an L shape.
