Abstract: An energy storage system is described that is capable of efficiently performing charging with respect to a power supply in which a cycle of supplied power fluctuates. The energy storage system is connected to a power supply in which a cycle of supplied power fluctuates. The energy storage system includes a first storage battery and a second storage battery having an internal resistance lower than an internal resistance of the first storage battery at a same voltage and a same capacity. The first storage battery and the second storage battery are connected in parallel.

Abstract: A lead-acid battery management system and a lead-acid battery management program are described that appropriately manage bipolar lead-acid batteries to reduce a degree to which the lead-acid batteries impose a load on environment as much as possible and are necessary to cause a circulation cycle from manufacturing to reuse to reliably function. A lead-acid battery system includes multiple bipolar lead-acid batteries and a management and support apparatus configured to manage the lead-acid battery system. The management and support apparatus includes a recording unit configured to record operation history information of the bipolar lead-acid batteries and a state determination unit configured to determine necessity of replacement of respective ones of the bipolar lead-acid batteries.

Abstract: An information management apparatus which can set an area in which use of a file is not allowed for each file separately is provided. The existing zone area information acquisition unit 61 acquires existing zone area information that is a condition set for each file and is information used for determination of whether a file is allowed to be used by being compared with a condition about an area in which use of a file is allowed or an area in which use of a file is forbidden. The determining unit 62 compares the existing zone area information and each condition set for each file, and determines whether each file to be a target of use by a user is allowed to be used or not.

Abstract: In a website browsing system image data of a website accessed from a portable terminal is converted to facsimile communication data by the portable terminal, sent to a facsimile and printed or displayed.

Abstract: When an electronic mail service center (40) receives a request for direct mail transmission from a company user terminal (10), it searches personal information stored in a database for general users satisfying a condition on a destination and automatically transmits a direct mail to general user terminals (20) of the users satisfying the condition. When the direct mail is in the form of a questionnaire, the electronic mail service center (40) receives the replies to the questionnaire from the general user terminals (20), compiles the replies, and transmits the compiled replies to the company user terminal (10).

Abstract: A mobile communication system includes a base station having a message transmission function and installed near a place where the use of a mobile unit is restricted. When the mobile unit in a wait state enters an area under management of the base station, the base station transmits a data signal for reproducing a message for instructing the mobile unit to turn off a power supply for the mobile unit.

Abstract: A communication apparatus using infrared rays (IR) and capable of receiving an IR signal without regard to its orientation is disclosed. An IR signal incident to the apparatus is transmitted through an IR signal inlet implemented by a one-way mirror. Subsequently, the IR signal is sequentially reflected by reflectors and the IR signal inlet to reach an IR signal receiving portion.

Abstract: A terminal unit of the present invention and applicable to a wired services network distinguishes two or more different kinds of plugs possibly connected to its general-purpose modular jack, reads a particular protocol matching the plug out of its storage, and then sets the protocol as its own protocol. Therefore, a plurality of data terminals each having a particular protocol can share a single terminal unit. In addition, a protocol adequate for a desired data terminal can be automatically set. This enhances the convenient use of terminal equipments.
