There is provided an in-vivo information acquisition apparatus capable of detecting high-accuracy in-vivo information substantially at the same time in a plurality of different examination sites in a body cavity and an in-vivo information acquisition apparatus system capable of introducing a plurality of in-vivo information acquisition apparatuses into a patient at the same time. The in-vivo information acquisition apparatus includes a specimen-collecting section for collecting a specimen at an examination site in a body cavity, a specimen-evaluating section for evaluating the specimen collected by the specimen-collecting section and outputting an evaluation result, a labeling section having identification information unique to the in-vivo information acquisition apparatus, a communication section for receiving a signal transmitted from the outside and for transmitting to the outside the evaluation result output by the specimen-evaluating section, and a power supply section for supplying electrical power.

The invention discloses an electric vehicle equipment power supply and distribution method, and relates to the field of power supply and distribution. The electric vehicle equipment power supply and distribution method aims to achieve the purposes that electric vehicle charging devices are wide in range, high in density and low in distribution spot cost. Traditionally, a bus of street lamps is provided with a power supply unit additionally for charging an electric vehicle, the bus supplies power all day, and the street lamps can be controlled to be turned off. The bus of the street lamps is divided into a plurality of sections in an isolating mode, and supplement power sources supply power in a subsection mode, so that the power supply capacity is multiplied. Isolating switches among the sections achieve combination of the sections and power supply changeover. On-site or remote communication is utilized for achieving recognizing, controlling, measuring and paying. When the street lamps are all used, semiconductor energy-saving lamps are used, a part of the lamps are turned off or used with the power reduced at midnight and the lamps are out of use in the daytime, electricity can be used by equipment such as electric vehicles day and night on the bus in a high power mode. The method can be applied to lines such as the street lamps which can be used discontinuously or of which the electricity load can be reduced, charging piles can be constructed widely and compatibly, so that the small electric vehicles can be charged at the early stage, electric cars can be guided to develop at the later stage, and a general and practical intelligent instrumented micro grid can be formed.

The image forming apparatus comprises: a liquid ejection head which has a plurality of nozzles and a plurality of pressure generating elements corresponding to the nozzles, and applies a drive signal to the pressure generating elements so as to eject recording liquid from the nozzles; a plurality of drive waveform generating circuits which generate the drive signal having waveform for driving the pressure generating elements; a plurality of dummy capacitive loads which are connected to the drive waveform generating circuits; and a circuit selection device which selects at least one of the drive waveform generating circuits for applying the drive signal to at least one of the pressure generating elements and the dummy capacitive loads.

A compact, inexpensive, large-capacity ozone generator with increased ease of apparatus maintenance. An ozone power supply includes an n-phase inverter for obtaining an AC voltage having a predetermined frequency and outputting an n-phase AC voltage waveform; n reactors and an n-phase transformer for converting an n-phase AC voltage to a high AC voltage; n high-voltage terminals for outputting the n-phase high AC voltage; and a low-voltage terminal having a common potential. Ozone generator units are electrically divided into n pieces within a discharge chamber. Each ozone generator unit includes n high-voltage electrode terminals and one low-voltage electrode terminal, common to all ozone generator units. Each ozone generator unit supports an n-phase AC discharge to generate ozone.
