Abstract:
A half-bridge inverter is used for a high frequency alternating current power supply to be connected to a primary side of a contactless power transformer, and a voltage-doubler rectifier is used to convert a secondary-side alternating current output of the contactless power transformer into a direct current.
Abstract:
A power transmitting device includes power transmitting coils, which contactlessly transmit electric power to a power receiving coil, and a switching device. When the power receiving coil is a solenoid coil, the switching device connects the power transmitting coils in parallel with each other such that magnetic fluxes generated inside the power transmitting coils flowing in the same direction along a winding axis. When the power receiving coil is a circular coil, the switching device connects the power transmitting coils in series with each other such that magnetic fluxes generated inside the power transmitting coils flowing in opposite directions along the winding axis.
Abstract:
A capacity management method of managing a capacity of a storage unit of each storage in a computer system having a plurality of storage devices each having one or more storage units each providing one or more storage areas. The method includes the steps of: detecting a storage area relation between a first storage area and a second storage area; and calculating an estimated capacity necessary for the storage unit in accordance with a detection result.
Abstract:
An elevator system has a pair of horizontally opposed vertical surfaces defining therebetween a doorway or opening to an elevator cage and a door moving horizontally to open and close the opening. In particular, the system has a first optical device having a light emitter for emitting light and a second optical device having a light receiver for receiving the light emitted from the light emitter. The first and second optical devices are positioned in a vertical plane crossing the opening and adjacent to the opening. One of the first and second optical devices is positioned below the other of the first and second optical devices and mounted in the vertical surface.
Abstract:
A flame retarding resin composition comprising 100 parts by weight of a specific rubber-reinforced resin, 1-200 parts by weight of a phenol resin, 1-200 parts by weight of an organic phosphorus compound, 1-50 parts by weight of a nitrogen-containing compound, 0-40 parts by weight of an oligomer-type polymer containing a functional group, 0-30 parts by weight of a metal compound, a silicon compound, and/or polytetrafluoroethylene, and 0-300 parts by weight of a styrene-type resin. The composition has high impact resistance, excellent heat resistance, and a superior self-fire-extinguishing characteristic.
Abstract:
A feeding device for independently feeding, by a preparatory device, a binder strip and flap strips to a garment held by a base presses. There are eight types of combination in feeding fashions, whether or not the binder strip is to be fed, whether or not one flap strip is to be fed, and whether or not another flap strip is to be fed (2.sup.3 =8). Various feeding fashions are provisionally set in order prior to actual sewing, and control means controls actual operations of the preparatory device in accordance with the feeding fashions and every feeding fashions.
Abstract:
Novel condurango glycoside compounds, antitumor agents comprising them and processes for their preparation, compositions containing them and methods of treating tumor with them are disclosed herein in which the novel condurango glycoside compounds are represented by the following formula (I): ##STR1## where X together with the 13 and 14 position carbon atoms is a group selected from the group consisting of ##STR2##
Abstract:
A contactless power transfer core used for a power transmission coil or a power reception coil of a contactless power transfer apparatus includes: a winding core part wound by an electric wire; and a magnetic pole core part constituting a magnetic pole portion provided at both sides of the winding core part. A height of the uppermost part of a ferrite plate arranged on a face of the magnetic pole core part at a side opposing a counterpart coil is equal to or greater than a height of an outer circumference of the electric wire wound around the winding core part, and a height of the ferrite plate of a face at a side not opposing the counterpart coil is lower than the height of the outer circumference of the electric wire wound around the winding core.
Abstract:
Provided is a contactless power transfer device for a moving object. Each of a power transmission coil and a power receiving coil comprises an H-shaped core, and first, second and third search coils are installed on a magnetic pole object of the H-shaped core of the power transmission coil. A y-direction positional deviation between the power transmission coil and the power receiving coil is detected using voltages measured at the first and second search coils, and an x-direction positional deviation is detected using voltages measured at the third search coils.
