A primary coil, a primary resonance coil, a secondary resonance coil, a secondary coil, and a load form a resonant system. A frequency matching section is configured to match the resonant frequency of a resonant system and the output frequency of a high frequency power source with each other when the load fluctuates. An impedance matching section is configured to match the impedance from input terminals of the primary coil to the load at the resonant frequency and the impedance from the high frequency power source to the input terminals of the primary coil with each other.

A wiring substrate manufactured by thinning a silicon substrate, which is coated by an insulation film, from a lower surface to an upper surface to form a substrate body. The substrate body is etched using a resist, which includes an opening, as a mask and the insulation film as an etching stopper layer to form a through hole and a cover, which covers an opening of the through hole at the upper surface of the substrate body. In a state in which the cover is formed, a functional element is formed on the upper surface of a further insulation film at the upper side of the substrate body. Then, a through electrode is formed in at least the through hole.

A storage subsystem includes: a controller; a first logical storage area corresponding to a RAID group configured by a plurality of storage devices; and a second logical storage area corresponding to a plurality of the RAID groups each configured by the plurality of storage devices, and storing a copy of data stored in the first logical storage area. In the storage subsystem, the first and second logical storage areas form a copy group, and for starting copying from the first to second logical storage area, the controller performs a mode change, from a power saving mode to a ready mode, to the plurality of storage devices configuring the plurality of RAID groups corresponding to the second logical storage area. With such a storage subsystem, the time can be reduced for activating copy-destination storage devices to which a power saving function is applied, and the copy time is thus favorably reduced.

A printer, which prints by repeatedly reciprocating a rolled recording paper and ejects a printed recording paper, has therein a recording paper storage unit in which the recording paper is temporarily stored. The recording paper storage unit has a configuration formed by at least a part of the periphery of the rolled recording paper or a configuration provided in a space between the rolled paper holder and an ejection slot. This configuration eliminates the need for separately providing a configuration in which a recording paper is set aside when printing a long sheet of printed material and, at the same time, makes the printer smaller.

A system comprises a first storage system, a second storage system, a plurality of switches, and a server connected with the first storage system via a first group of switches and connected with the second storage system via a second group of switches. The first group and the second group have at least one switch which is not included in both the first and second groups. The first storage system receives I/O commands targeted to first logical units from the server via the first group of switches. The first storage system maintains first information regarding the ports of both the first and second storage systems. The first information is used to generate multipath communication between the server and the first storage system, including at least one path which passes through the second storage system and at least one other path which does not pass through the second storage system.

A wiring substrate includes a silicon substrate, a through hole formed to penetrate the silicon substrate in a thickness direction, an insulating layer formed on both surfaces and side surfaces of the silicon substrate and an inner surface of the through hole, a penetration electrode formed in the through hole, a wiring layer formed on at least one surface of the silicon substrate and connected to the penetration electrode, and a metal wire terminal connected to the wiring layer and formed to extend from one surface of the silicon substrate to a side surface thereof. The metal wire terminal on the side surface of the electronic device is connected to the mounting substrate such that a substrate direction of the electronic device in which an electronic component is mounted on the wiring substrate intersects orthogonally with a substrate direction of the mounting substrate.

It is necessary to install a program called an agent in order to keep track of how much a file system on a computer uses a disk. On this account, loads might be applied to a server due to installation work or the agent program to increase primary costs. In addition, software inside a storage device determines and records a target block for data input/output and keeps track of capacity utilization, which might degrade the input/output performance of the storage device. A computer system is provided in which configuration information and operating information are acquired from a storage device, when data input/output is made from a computer to a logical unit, it is determined that the computer uses the logical unit to which input/output is made, and capacity used by the computer is computed.

A semiconductor package includes a wiring board and a semiconductor device mounted on the wiring board. At least one penetration hole extends from one surface of the semiconductor chip to an opposite surface of the semiconductor chip. A penetration electrode is situated inside the penetration hole without contacting a wall of the penetration hole. The penetration electrode has one end fixed to the one surface of the semiconductor chip and an opposite end protruding from the opposite surface of the semiconductor chip. A connection terminal is formed on the opposite end of the penetration electrode and electrically connected to the wiring board.
