摘要:
A wireless communication method and a wireless communication apparatus capable of efficiently improving communication throughput of a second wireless communication system while securing a capturing capability of informative information in a first wireless communication system are provided. A transmitting/receiving unit (2, 3, 6) capable of transmitting/receiving information through first and second wireless communication systems (1x and EVDO) and a receiving unit (4, 7) capable of receiving information through the first and second wireless communication systems and whose reception gain in the first wireless communication system is smaller than the transmitting/receiving unit are used to detect that a reception sensitivity of informative information notifying a reception by the transmitting/receiving unit through the first wireless communication system has exceeded a first threshold or a second threshold set in accordance with a reception gain difference between the transmitting/receiving unit and the receiving unit when information is being transmitted/received by the transmitting/receiving unit through the second wireless communication system, and to switch reception of the informative information from the transmitting/receiving unit to the receiving unit.

A housing has a compression chamber and a first passage, through which the compression chamber communicates with an accumulation chamber. A discharge valve is provided in the first passage and configured to open to supply fuel from the compression chamber to the accumulation chamber in response to increase in pressure in the compression chamber. A second passage is configured to communicate the accumulation chamber with the compression chamber via the discharge valve. A valve element allows fuel flow from the accumulation chamber to the compression chamber. A biasing unit biases the valve element to seat the valve element on a valve seat of the second passage. The sidewall of the valve element and the inner wall defining the second passage therebetween define a throttle midway through the second passage for restricting fuel flow from the accumulation chamber to the compression chamber.

A nozzle surface cleaning apparatus wipes a nozzle surface of a droplet ejection head. The apparatus includes: a wiping member which wipes the nozzle surface in which a nozzle aperture is formed; a head movement device which causes movement of the droplet ejection head in a head movement plane and in a head movement direction; and a fine vibration device which causes vibration of one of the wiping member and the droplet ejection head in a vibration plane and in a vibration direction, the vibration plane being parallel to the head movement plane, the vibration direction being different to the head movement direction.

A memory management method and a system for performing garbage collection. The method includes the steps of providing in a memory space a heap partitioned into a plurality of areas including an area for object allocation and a To area for future object allocation. In garbage collection, an object reachable from a root set among objects allocated in the area of use is copied into the To area. In addition, a finalizable object among the objects allocated in the area of use is set as a finalization target. Here, the finalizable object is an object unreachable from the root set and has a finalize method. After the garbage collection is completed, the finalizable object of finalization target allocated in the area of use is finalized.

A monolithic organic porous body includes a continuous macropore structure that includes cellular macropores that overlap to form openings having an average diameter of 20 to 200 μm, the monolithic organic porous body having a thickness of 1 mm or more and a total pore volume of 0.5 to 5 ml/g, an area of a skeleton observed within an SEM image of a section of the continuous macropore structure (in a dry state) being 25 to 50%. A monolithic ion exchanger is produced by introducing an ion-exchange group into the monolithic organic porous body. The monolithic organic porous body and the monolithic ion exchanger are chemically stable, have high mechanical strength, and ensure a low pressure loss when fluid passes through. The monolithic organic porous body and the monolithic ion exchanger may be used as an adsorbent having a large adsorption capacity or an ion exchanger having a large ion-exchange capacity.

Supply of power is ensured on use without requiring troublesome works such as battery replacement work and charging work. Specifically, hearing aids, which collect sound, amplify the collected sound, and output the amplified sound, boosts electromotive force generated by the Peltier module derived from temperature difference between a human-body contact portion and an ambient-air contact portion, and causes sound collecting units, a controller IC, a speaker to operate by the boosted voltage.

In a pressure sensor including a pressure detecting element in an intermediate portion or at a deep side of a through hole formed in a protrusion, a body portion (a base portion and the protrusion) is made of ceramic or an insulative resin material and molded into a predetermined shape, and the pressure sensor is constituted as a molded interconnect device in which a conductive pattern is formed on a surface thereof. Accordingly, a smaller pressure sensor can be obtained.

A battery includes a spirally wound electrode body in which a cathode and an anode are layered with a separator in between and spirally wound. The spirally wound electrode body is attached with at least one lead on the spirally-winding center side. The cathode has a cathode current collector having a pair of opposed faces, an outer-face cathode active material layer provided on the spirally-winding outer face side of the cathode current collector, and an inner-face cathode active material layer provided on the spirally-winding inner face side thereof. A thickness of the inner-face cathode active material layer is smaller than a thickness of the outer-face cathode active material layer. An outer face active material region provided with only the outer-face cathode active material layer is formed to be overlapped with the lead on the spirally-winding center side of the cathode.
