Abstract: Mobile communication systems and base station control apparatuses are provided, by which a spectral efficiency can be improved while preventing interference between a terrestrial cellular mobile communication system and a satellite mobile communication system, and mobile communication services using mobile station apparatuses can be provided more surely in an emergent condition in which a failure occurs in a part of terrestrial cellular base stations. A same frequency band is used for radio communications between a mobile station apparatus 10 and each of terrestrial cellular base stations 20 and a communication relay apparatus 41 of artificial satellite 40.

Abstract: There is provided a rotary type regenerative heat exchanger which can effectively prevent an air bypass leak or a gas bypass leak. A rotary type regenerative heat exchanger of the present invention has a rotor (4) rotating around a central shaft (2), a heat accumulator (8) which is constructed in a manner that an air (A) of being a heated fluid and a gas (G) of being a heating fluid filled in the rotor alternately pass therethrough by a rotation of the rotor to repeat heat accumulation and radiation, and a housing provided so as to house the rotor. Further, the rotary type regenerative heat exchanger comprises: a branch pipe (41, 47, 55) for taking out a part of the heating fluid; a seal gas fan (42, 48, 56) for pressurizing the taken-out heating fluid to a predetermined pressure; and a seal gas introducing duct (46, 52) which is provided in the housing so as to introduce the pressurized heating fluid into a predetermined space formed between the rotor and the housing.

Abstract: When a content to be partialized is specified to a document, the document creation supporting system records the content of the part in a file separated from the document together with a part holding mark, adds a part reference mark at the position where the part is specified in the document and deletes the content of the part from the document in order to be able to readily confirm the consistency of the part and version number when the document is updated and to be able to confirm contents of documents among a plurality of documents.

Abstract: A cooking stove such as an induction heating cooking stove which is fitted into an aperture on top of a kitchen unit has one or more independent heater units mounted within an outer case, below a top plate which cooking pans, etc can be heated. Each heater unit consists of an open-ended box-shaped internal chassis having one or more heater elements mounted on a top face thereof and an aperture formed in a bottom face thereof. Each internal chassis is provided with a motor-driven cooling fan which acts to produce a flow of cooling air through the interior of the chassis and out through the lower aperture into a ventilation duct, and hence to the atmosphere via a cooling air inlet/outlet section which can be conveniently provided at the upper rear part of the top of the stove. No additional ventilation apertures need be provided in the kitchen unit, and the number of heater elements can be readily varied as required, while the overall design is extremely simple and readily manufactured.

Abstract: A cooking stove is provided with a top plate, for receiving cooking utensils, which can be easily and rapidly removed for servicing purposes, etc. The top plate is retained against the stove housing by a very simple catch mechanism at the front and is attached to the housing at the rear by means of screws, at a position adjacent to an air inlet/outlet aperture, with a cover of this aperture also serves to mask the screws, for improved appearance.

Abstract: A cooking appliance unit including a top plate on which food items are cooked, a horizontal frame formed around the outer periphery of the top plate, having inlet and outlet ventilation holes on only one side thereof, and a cooking appliance body below the plate and frame having walls defining first, second and third chambers therein. A heating device is provided in the second chamber below the top plate. A control device is provided in the first chamber, the first chamber being in fluid communication with the inlet holes, and the second chamber through a ventilation opening in a partition wall. The third chamber is disposed below the second chamber separated by another partition wall which contains a cooling fan, the third chamber being in fluid communication with the exhaust holes.
