A method for charging a secondary battery by measuring the static/open circuit voltage and comparing it to a predetermined value includes: a first step of precharging the secondary battery; thereafter pausing a predetermined interval; a step of measuring a secondary battery voltage Vba1 after performing the pausing; and a step of charging the secondary battery based on the measurement of the secondary battery voltage Vba1.
摘要:
A thin film magnetic head has a lower magnetic layer and an upper magnetic layer formed over the lower magnetic layer so that a small gap is formed between a magnetic gap section of the lower magnetic layer near a sliding surface to be brought into sliding contact with a magnetic recording medium and a magnetic gap section of the upper magnetic layer extending in parallel to the magnetic gap section of the lower magnetic layer near the sliding surface. The upper magnetic layer has a first sloping section extending from the magnetic gap section at an inclination .theta..sub.1 in a range defined by 2.degree..ltoreq..theta..sub.1 .ltoreq.25.degree. to the upper surface of the lower magnetic layer, and a second sloping section extending from the first sloping section at an inclination .theta..sub.2 in a range defined by: 30.degree..ltoreq..theta..sub.2 .ltoreq.80.degree. to the upper surface of the lower magnetic layer. Magnetic flux leaks across the lower magnetic layer and the first inclined section of the upper magnetic layer, so that the magnetic saturation of the magnetic gap section of the upper magnetic layer is prevented. Since the second sloping section is inclined at a large inclination, the overwrite characteristics is not deteriorated.

A method for manufacturing an antenna device is provided. The manufacturing method includes forming an antenna circuit so that the resonance frequency of the antenna circuit will be lower than an oscillation frequency of the reader/ writer and affixing a magnetic sheet to an antenna coil via an adhesive. The antenna circuit includes the antenna coil that receives the magnetic field transmitted from the reader/ writer and a capacitor electrically connected to the antenna coil. The magnetic sheet is at a face-to-face position with respect to the antenna coil and is configured to change the inductance of the antenna coil. The adhesive is of a film thickness to change the inductance so that the resonance frequency of the resonance circuit will be coincident with the oscillation frequency depending on the spacing between the antenna coil and the magnetic sheet.

The present invention provides an antenna apparatus which can realize favorable communication properties while achieving downsizing of a casing of an electronic device when incorporated in an electronic device. An antenna module (1a) which is incorporated in a mobile phone (130) and which is enabled to perform communication by receiving a magnetic field transmitted from a reader/writer (120) comprises an antenna coil (11a) which is wound in a clearance (132) between an end portion (133b) of a metallic plate (133a) opposing the reader/writer (120) within a casing (131) of the mobile phone (130) and an inner peripheral wall (131a) of the casing (131) so as not to surround an outer peripheral portion of the metallic plate (133a) and which is inductively coupled with the reader/writer (120).

A carburetor includes a valve mechanism, and a needle jet extending in an up and down direction. Also included is a jet needle provided to a sliding throttle valve disposed in an air intake tube and inserted into the jet needle. The valve mechanism includes a valve body, which has a plate shape and which is moved by the flow of the fuel. When a motorcycle lands on the ground after the motorcycle jumps while running, the fuel-in-jet, that is, the fuel in the needle jet, tends to accelerate downwardly. The valve mechanism prevents a downward reverse flow of the fuel-in-jet on which such downward acceleration acts. The resulting configuration prevents temporary production of a lean air-fuel mixture, which may possibly be produced when the fuel in the needle jet has accelerated downwardly.

摘要:
A magnetic reluctance effect magnetic head in which a forward side electrode is stacked on at least the surface of a magnetic reluctance effect element facing a magnetic recording medium, and in which an upper magnetic pole is stacked on the forward side electrode for facing the magnetic reluctance effect element. A connecting length L1 between the magnetic reluctance effect element and the forward side electrode is shorter than a facing length L2 over which the upper magnetic pole and the magnetic reluctance effect element face each other via a magnetic gap G. The upper magnetic pole and the magnetic reluctance effect element have an area in which the upper magnetic pole and the magnetic reluctance effect element face each other over a distance g2 larger than a magnetic gap length g1 of the magnetic gap G. The upper magnetic pole may be formed to be progressively spaced apart from the magnetic reluctance effect element by being angled 30.degree. relative to the magnetic reluctance effect element, and the distance g2 may be progressively increased. With the magnetic reluctance effect magnetic head, the playback output may be improved and the magnetic head may be reduced in size and in the power consumption.
