A magnetic field detection apparatus capable of changing the detection range and detection sensitivity as desired for a specific application is disclosed. A magnetoresistance effect element is applied a bias magnetic field and an external magnetic field. The bias magnetic field and the external magnetic field are generated on the same straight line, and therefore the bias magnetic field functions to hamper the external magnetic field applied to the magnetoresistance effect element. Thus, the magnetization of the free layer of the magnetoresistance effect element is suppressed, and the rotational angle of the magnetized vector is reduced. As a result, the characteristic of the resistance value of the magnetoresistance effect element to the external magnetic field is shifted by an amount equivalent to the bias magnetic field.

A substrate processing apparatus comprises an indexer block, an anti-reflection film processing block, a resist film processing block, a development processing block, and an interface block. An exposure device is arranged adjacent to an interface block. The interface block comprises a drying processing group including two drying processing units and an interface transport mechanism. After a substrate is subjected to exposure processing by the exposure device, the substrate is transported to the drying processing units in the drying processing group by the interface transport mechanism, where the substrate is subjected to cleaning and drying processings.

The present invention provides a connector capable of being simply and easily connected without loss of electrical continuity even in a harsh environment.First joining terminals 201a and 201b are supported by a female housing 200, and second joining terminals 401a and 401b electrically connected to the first joining terminals 201a and 201b are supported by a male housing 400. The male housing 400 is inserted to mate with the female housing 200, which performs electrical connection. Further, slit ribs 205a to 205d are formed in the direction of mating in the female housing 200, and slits 405a to 405d along the direction of mating are formed in the male housing 400. The slit ribs 205a to 205d have recessed tapered shapes formed at a predetermined rate of angular change and a predetermined rate of width change, and the slits 405a to 405d have tapered shapes having a rate of angular change and a rate of width change which are respectively greater than the predetermined rate of angular change and the predetermined rate of width change of the slit ribs.

To provide a semiconductor device member that is superior in heat resistance, light resistance, film-formation capability and adhesion, and is capable of sealing a semiconductor device and holding a phosphor without causing cracks, peelings and colorings even after used for a long period of time, the weight loss at the time of heating, measured by a predetermined weight-loss at-the-time-of-heating measurement method, is 50 weight % or lower and the ratio of peeling, measured by a predetermined adhesion evaluation method, is 30% or lower, in the semiconductor device member.
摘要:
A flexible cable establishes an electric connection between a stationary-side housing and a movable-side housing. The flexible cable is integratedly fabricated with two gasket seals that maintain the inside of the stationary-side housing and the movable-side housing, respectively, in a waterproof condition. A reinforcing plate is laid inside a housing of a movable-side front case to prevent a driver circuit board of a LCD module from getting damaged.

A carriage block body is coupled to a support shaft for relative rotation. The carriage block body defines a bearing hole receiving the support shaft. A carriage arm extends from the carriage block body along an imaginary plane perpendicular to the longitudinal axis of the support shaft. The carriage arm has a wall surface defining a cylindrical space at the tip end of the carriage arm. A projection is formed on the wall surface at a position off an intermediate plane set perpendicular to the longitudinal axis of the cylindrical space so that the cylindrical space is equally divided into a first cylindrical space and a second cylindrical space by the intermediate plane. The projection protrudes into the first cylindrical space.

When crimping suspensions to carriage arms using a metal ball by applying ultrasonic vibration to a crimping tool, the suspensions can be crimped to the carriage arms without causing deformation to the suspensions and the like. A method of assembling a carriage assembly aligns attachment holes provided in front ends of carriage arms and crimping portions provided on suspensions to set the suspensions on the carriage arms and then presses a ball through crimping holes provided in the crimping portions while applying ultrasonic vibration to the crimping tool to crimp the suspensions to the carriage arms. When doing so, a ball, such as a ball whose surface has been subjected to a dimpling process, for which a load that acts on the ball when the ball passes through the crimping holes is low compared to a spherical ball is used to crimp the suspensions to the carriage arms.
