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:
According to one embodiment, contactless power transfer apparatus includes: transmission coil; primary capacitor; reception coil opposing transmission coil through gap; and secondary capacitor. Specification of frequency of the transmission coil and that of the reception coil are equal. At least one of electrical power specification and gap length specification of the transmission coil differ from the reception coil. When the electrical power specification of the power transmission coil differ from that of the power reception coil, the power is supplied from the transmission coil to the reception coil by using smaller one of the power of the transmission coil and of the reception coil as maximum power. When the gap length specification of the transmission coil differs from that of the reception coil, the transmission coil opposes the reception coil through the gap length, which is the specification of the transmission coil.

Moreover, the illumination optical system illuminates the inspecting object with another slit beam from a direction opposite to an incident direction of the slit beam on a plane.
Abstract:
[Problems] To provide a non-contact power feeder that is high efficient and high power factor and has no load dependence.[Means for Solving Problems] A series capacitor Cs1 is connected to a primary winding 1 driven by an AC power supply 3 and a parallel capacitor Cp2 is connected to a secondary winding 2. The capacitance Cp is set to Cp≈1/{2πf0×(x0+x2)} and the capacitance Cs converted to the primary side is set to Cs≈(x0+x2)/{2πf0×(x0×x1+x1×x2+x2×x0)}, where f0 is the frequency of the power supply, x1 is a primary leakage reactance of the primary winding 1, x2 is a secondary leakage reactance of the secondary winding 2 converted to the primary side and x0 is an excitation reactance converted to the primary side. By setting Cp and Cs to the above values, the transformer of the non-contact power feeder is substantially equivalent to an ideal transformer. If it is driven by a voltage type converter, the output voltage (=load voltage) becomes substantially constant voltage regardless of the load. In case of a resistive load (ZL=R), the power factor of the power supply output always remains 1 even if the load may vary.
Abstract:
A burden placed on an administrator in creating a volume is reduced. An evaluation hint value and a performance hint value are employed as hint values for each hint. The evaluation hint value is determined by the administrator considering a service usage and the like of the service server 1 to which the volume is allocated. The performance hint value is used to determine a performance and a setting of the volume to be created in the storage system 3. The management server 2 has a conversion table indicating a correspondence between the evaluation hint value defined considering the hardware configuration and the performance hint value, with respect to each storage system 3. The management server 2 converts the evaluation hint value designated by the administrator to a performance hint value, by use of the conversion table associated with the storage system to which the volume is to be created, and the management server creates the volume in the storage system 3 according to the performance value.

Abstract:
The present invention provides a high-performance storage access environment to a user who moves around a wide area, while increasing the fault resistance of the system. A plurality of network storages (volumes) is assigned to the user. Then, at the occasion of logging in to a volume by the user, the volume that can be accessed with high performance from a position he made access is located. Addresses at a computer with which user makes access are associated with addresses of the volumes provided by a storage device in advance in an assigned volume management table so as to increase access performance. Then, a management server performs control so that the address of the volume associated with the user access position is returned as a response, at the time of logging in.
Abstract:
In a multi-deck-elevator-equipped building control system, operating modes of an elevator control portion include a double operating mode. In the double operating mode, only a first cage is permitted to stop at first cage stop floors, and only a second cage is permitted to stop at second cage stop floors that are distinct from the first cage stop floors. A building fixture control portion has a first group control portion for associatively controlling an electrical fixture on the first cage stop floors and a second group control portion for associatively controlling an electrical fixture on the second cage stop floors.
Abstract:
An intake port for guiding new intake air into a combustion chamber of a cylinder and an exhaust port for discharging exhaust combustion gas from the combustion chamber to the outside, are formed in a cylinder head mounted on the cylinder for housing a piston movably in a reciprocating manner. The intake port is opened/closed by intake valve, and the exhaust port is opened/closed by exhaust valve. Openings of the intake and exhaust ports at the combustion chamber side are formed to be displaced toward central portion of the combustion chamber. An inclining angle of the intake valve formed between the central axis of the intake valve and the central axis of a cylindrical bore of the cylinder is set larger than an inclining angle of the exhaust valve, formed between the central axis of the exhaust valve and the central axis of the cylindrical bore of the cylinder, and a bulge portion is formed on the inner surface of the intake port, oppositely to a valve guide for guiding movably the intake valve of the intake port.
Abstract:
After a reducing gas is mixed with an inert gas by a mixer, a resultant mixed gas is heated by a heater and made to a hot mixed gas which is dehumidified and dried and the temperature of which is increased. The mixed gas is injected to a subject from an injection port formed in a soldering iron, and thereby soldering is performed by heating and melting solder with the soldering iron in the atmosphere of the mixed gas.
