  • Publication number: 20210226679
    Abstract: This invention is a transmission device capable of enhancing the reception characteristics of a terminal when employing transmit diversity using two antenna ports in an ePDCCH. In a base station (100) that transmits a reference signal to a terminal (200) using two antenna ports, a setting unit (102), on the basis of the reception quality of the terminal, sets as the aforementioned two antenna ports either a first antenna port pair for which DMRS (reference signals) do not undergo mutual code multiplexing, or a second antenna port pair for which the DMRS do undergo code multiplexing. A transmitter (109) transmits the DMRS from the two antenna ports set in the setting unit (102).

  • Patent number: 10651442
    Abstract: An assembled cell is formed by laminating a plurality of rectangular secondary batteries in a thickness direction and interposing a spacer between the rectangular secondary batteries. The rectangular secondary battery includes an electrode group in which positive and negative electrodes are wound, and the electrode group is housed in the battery container formed in a flat box shape. The spacer includes a contact part which contacts with a width direction end region of a wide side surface of the battery container, a facing part which faces a width direction intermediate region of the wide side surface, and an inclined surface which is adjacent to both ends of the facing part in a width direction of the wide side surface. The inclined surface is inclined such that a thickness of the spacer becomes asymptotically smaller in a direction toward the width direction intermediate region from the width direction end region.

  • Patent number: 10648477
    Abstract: A state observation device (30) uses an ADC (37) to digitize a detection signal from a gap sensor (21) at a low-speed sampling period and uses a separation unit (38) to separate the digitized detection signal into vane detection signals considered to be for the detection of a vane of a compressor impeller and non-vane detection signals considered not to be for the detection of a vane. Further, the determination unit (39) extracts a vane peak detection signal considered to be for a vane peak by comparing a vane detection signal with vane detection signals corresponding to other vanes and non-vane detection signals, and a shaft vibration and tip clearance are determined as states of the compressor impeller on the basis of the extracted vane peak detection signal. Thus, the state observation device (30) is capable of observing the state of a rotary machine without carrying out high-speed sampling.

  • Patent number: 9325040
    Abstract: An electrical storage apparatus 1 includes a plurality of battery modules 10 and cooling passages A, B for cooling each of the battery modules 10. The cooling passage A is configured so as to cool all battery modules 10 mounted in the electrical storage apparatus 1 at all times during charging. The cooling passage B is configured so as to cool only a new battery module 10a as a replacement during charging. This enables the battery module 10a having a temperature during charging higher than that of a battery module 10 yet to be replaced to be subject to forced cooling, thereby preventing performance of the battery module 10a from being degraded.
