Filed: 2008-02-18
Abstract: 【解決手段】連続的糸球体濾過率（ＧＦＲ）評価システムは、フォーリーカテーテル、連続的尿クレアチニンセンサー、及び尿排出モニターを備えている。連続的ＧＦＲ評価システムは、クレアチニンクリアランスを、ＣｒＣｌ＝（Ｕ Ｃｒ ×Ｕ ｖｏｌ ）／（Ｐ Ｃｒ ×Ｉ ｍｉｎ ）として算出する。ここで、Ｕ Ｃｒ は、尿クレアチニンであり、単位はｍｇ／ｄＬである。Ｕ ｖｏｌ は、尿の体積であり、単位はｍＬである。Ｐ Ｃｒ は、プラズマ（血清）クレアチニンであり、単位はｍＬである。Ｉ ｍｉｎ は、時間であり、単位は分である。フォーリーカテーテルは、膀胱から尿を回収するために使用することができる。尿は、時間Ｉ ｍｉｎ に渡ってＵ ｖｏｌ 値を提供する尿排出モニターに送られる。カテーテルに取り付けられているのは、Ｕ ｖｏｌ 値を提供するための流動連続的クレアチニンセンサーである。残りのパラメータは、Ｐ Ｃｒ である。血清クレアチニンレベルは、時間的に急激には変化しないので、血液サンプルを、連続的ＧＦＲの開始に先立って回収しておき、それによりＰ Ｃｒ 値を得る。 【選択図】図３

Title: 二重クラッドスタブファイバを備えたファイバ光学コネクタ
IPC: G02B6/26
Filed: 2008-03-06
Abstract: ファイバ光学コネクタは、深い屈折率のコアから内部クラッディングへのプロフィールと、高められた屈折率の外部クラッディングのプロフィールとを備えた二重クラッド光学スタブファイバを持つ。二重クラッド光学スタブファイバは、高次モードで著しく干渉することなく主要モードが横断する接合部を形成するために、単一クラッドフィールド光学ファイバで終端する。スタブファイバのコアの半径に対する内部クラッディングの半径の比は６．５：１より小さい。内部クラッディングの屈折率の屈曲率プロフィールは、コア中で主要モードを制限するために、コアの屈折率と比較して深い。外部クラッディングの高められた屈折率は、その領域中でさらに深い高次モードを引き、主要モードによる干渉を減らす。フィールドおよびスタブファイバのコア径は、モード−フィールド直径不整合を避けるために一致させられる。

IPC: F24C15/14
Filed: 2010-01-06
Abstract: <P>PROBLEM TO BE SOLVED: To provide a drip pan cover for a stove burner capable of reducing the total strain generated in installation.  <P>SOLUTION: This drip pan cover 1 for the stove burner is disposed between a body 71 and a drain pan 73, and a trivet 74, and includes a strain absorbing section 2 composed of a strain absorption recessed section 7 and a strain absorption projecting section 8 on a position corresponding to a projection piece inserting section 72. In installation, when the strain absorption recessed section 7 is pressed down to the projection piece 76, the strain absorption projecting section 8 is collapsed in accompany therewith. When the projection piece 76 is further lowered, a penetrating section 3 is formed on the strain absorption recessed section 7, the projection piece 76 is inserted to a projection piece inserting section 72, and a position of the trivet 74 is fixed. As the strain by pressing of the projection piece 76 is absorbed by the strain absorbing section 2, the outer edge shape and inner edge shape themselves of the drip pan cover 1 for the stove burner hardly strain. Thus risk of degradation of a function of covering the drip pan for the stove burner due to deformation of the shapes of the drip pan cover 1 for the stove burner in installation can be eliminated.  <P>COPYRIGHT: (C)2011,JPO&INPIT

Abstract: <P>PROBLEM TO BE SOLVED: To solve the problem of conventional single-wafer ultrasonic-wave spin cleaning apparatuses of an ultrasonic-wave vibrator type which use cleaning liquid, such as deionized water, to clean an object such as a wafer, wherein even though the apparatuses have an advantage that the damage given to the wafer surface by the cleaning is small, their cleaning time for removing foreign materials such as contaminants is long.  <P>SOLUTION: The cleaning apparatus to be disclosed has a structure, such that a vibrator itself is rotated around its vertical axis in an ultrasonic-wave radiating plane so that the cleaning liquid in a gap between the ultrasonic-wave radiating plane of the vibrator that propagates ultrasonic vibration and the wafer surface can be actively agitated. Accordingly, the probability that the foreign materials removed from the wafer surface by the ultrasonic-wave vibration and floating in the cleaning liquid deposit again on the wafer surface is markedly reduced, and the cleaning time can be greatly reduced, by forcing the contaminated cleaning liquid to flow out rapidly from the gap which is the cleaning action region.  <P>COPYRIGHT: (C)2011,JPO&INPIT
