Immunological test method

Номер: US5476796A
Принадлежит: Olympus Optical Co Ltd

A test method for determining the presence or absence of an antigen or antibody analyte in a sample. The sample is first reacted in a reaction vessel with magnetic carrier particles having immobilized thereon a substance which specifically binds to said analyte, thereby forming bound and unbound magnetic carrier particles. The bound and unbound magnetic carrier particles are then precipitated on a flat and substantially horizontal inside wall surface of said reaction vessel with a magnet provided outside the reaction vessel, such that a gradient magnetic field is formed in a plane perpendicular to a direction in which the bound and unbound magnetic particles are precipitated, thereby forming a precipitation image on the wall surface. Finally, the presence or absence of the analyte is determined by the shape of the precipitation image. The gradient magnetic field is formed by placing the magnet outside said reaction vessel such that the distance between the wall surface of the reaction vessel on which the precipitation image is formed and the surface of the magnet opposing the wall surface is gradually increased, thereby forming an effective angle between the magnet and the wall surface. The precipitation image is formed independently of the shape of the reaction vessel. When the wall surface of the vessel is flat, it is very easy to stably maintain the precipitation image after its formation.

When an actuation mechanism fails to operate and thus fails to control a turning of a control shaft of a valve lift varying mechanism, a moving member is enforcedly moved to an intermediate stable position by a biasing force that is produced by combining a first type force that biases the control shaft in a direction to increase a valve lift degree of an engine valve and a second type force that biases the control shaft in a direction to reduce the valve lift degree of the engine valve. The intermediate stable position of the moving member assures an easy engine starting even in a cold engine condition.

(57)【要約】 【課題】 レンジ位置を高速側から低速側へ切り換えた ときに、急激な回転数の上昇による吸排気弁の不正運動 を有効に阻止する。 【解決手段】 レンジ位置検出スイッチ126によって レンジ位置の高速側から低速側への切換開始が検出され た時、低速側の変速マップから目標変速比を検出し、こ の目標変速比と車速センサ109で検出される車速とに 基づいて、変速終了時の機関回転数を推定する。この推 定回転数が、ポテンショメータ47で検出されるバルブ リフト特性に応じて設定される限界回転数を越える場合 に、低速側変速マップを、そのダウン側の変速線が相対 的に低車速側へずれるように補正する。
