A DC / AC converter is disclosed having two DC voltage connections (1,2), between which are provided in a parallel circuit configuration, an intermediate energy storage (C1) and a bridge circuit providing at least two parallel branches, each branch providing two in-series-connected switch units (A,B and C,D), to each of which a rectifier diode (DA,DB,DC DD) is connected in parallel, and having at least two AC connections, of which each single AC connection is connected via a connecting line, in each of which an inductor (L1 respectively L2) is provided, to one of the parallel branches of the bridge circuit between two the switch units (A,B respectively C,D) via one connecting node. In at least two connecting lines, two separate electrical connecting paths are provided, in each of which a switch (E respectively F) and an in-series-switched rectifier diode (DE respectively DF) are provided. The rectifier diodes (DE,DF) in the single connecting paths are switched in an opposite conducting direction.

The present invention relates particularly to photovoltaic roofing systems in which photovoltaic elements are integrated on a roof deck with conventional roofing materials. In one aspect, a photovoltaic roofing system includes a two-part tee element disposed on a roof deck, the two-part tee element comprising a base piece including a central portion; two opposed horizontally-extending first and second flanges extending from the central portion, and a top piece attachment feature formed in the central portion, and a top piece including a base piece attachment feature mated with the top piece attachment feature of the base piece; and a vertically extending portion extending from the base piece attachment feature. A first photovoltaic element can be disposed on the roof adjacent the base piece with its edge disposed on the horizontally-extending first flange of the base piece of the two-part tee element.

An apparatus for holding and storing tools in a vehicle, including a storage body shaped to fit inside the hub of a spare wheel. The storage body has a jack storage space for securely holding a vehicle raising jack, a lug wrench-receiving space for securely holding a lug wrench and a hollow storage well for holding and storing one or more various user-selected tools or accessories. The storage well has a volume approximately as large as said jack storage space. The storage well may be substantially crescent shaped in cross section and extends substantially the full depth of the storage body for thereby providing a relatively large storage space in a otherwise restricted area of a vehicle trunk. Optionally, tools may be added to the storage body, and fitted into the appropriate storage spaces therein, to form a compact tool kit and storage receptacle for a vehicle.

An image forming apparatus includes a first fixing device that applies heat to a non fixed toner image and a second fixing device arranged downstream of the first fixing device, which applies pressure and fixes the non-fixed toner image onto a recording member.

A hybrid hydraulic power transmission system for all terrestrial's vehicles comprises a prime mover and an accumulator which could also be used as the main load bearing full or partial frame for all those vehicles. A hydraulic power integrator is operatively connected to the prime mover and the accumulator and selectively able to draw power for the vehicle from the prime mover, the accumulator, or a combination thereof.

A cellular phone control apparatus uses a predetermined association between a cellular phone and a call destination for controlling use of plural cellular phones. The predetermined association is stored in a memory of the control apparatus, and the call destination specified by a user is reflected to a selection of the cellular phone for placing a call to the call destination based on the predetermined association. In this manner, the user can selectively use plural cellular phones without changing configuration of the cellular phone control apparatus.

The present invention provides a computed tomography system that only requires rotational scans for image pickup, the system enabling images of a plurality of testing objects to be simultaneously picked up without increasing the volume of noise or the scale of the system, thus enabling high-quality tomographic images to be efficiently picked up. In the computed tomography system, a plurality of turn tables 11a to 11d are provided in a region of irradiation with X-ray beams emitted by an X-ray irradiation system. Testing objects Ma to Md are placed on the respective turn tables. Images of the plurality of testing objects can be simultaneously picked up by irradiation with X-ray beams. This enables precise image pickup to be efficiently achieved without increasing the size of the scale.
