Patent number: 10293188Abstract: A method and apparatus is disclosed for determining the success of a proposed HIFU Treatment, of an ongoing HIFU Treatment, and/or of a completed HIFU Treatment. An energy density of a given HIFU Treatment may be used as a comparison factor between the given HIFU Treatment and other HIFU Treatments and as a predictor of the success of the given HIFU Treatment. One exemplary energy density is the amount of energy deposited in the treatment region divided by the volume of the treatment region. Another exemplary energy density is the amount of energy deposited in the treatment region divided by the pre-treatment mass of the treatment region. A method and apparatus is disclosed to detect the presence of focal hyperechoic features and non-focal hyperechoic features. A method and apparatus is disclosed to detect the presence of an acoustic obstruction.Type: GrantFiled: July 20, 2015Date of Patent: May 21, 2019Inventors: Russell J.

Patent number: 5521097Abstract: A protein or peptide is treated by a vapor containing an organic acid represented by the following general formula CF.sub.3 --(CF.sub.2)n--COOH (n is zero or more integer). The resulting reaction mixture is processed by a mass spectrometer to obtain a mass spectrum to measure a mass of respective chemical species contained in the reaction mixture. Alternatively, the reaction mixture is processed by an amino acid analyzer to determine an amino acid sequence of the protein or peptide from the carboxy-terminal. According to another method, the protein or peptide is treated by an anhydride of the organic acid represented by the following general formula CF.sub.3 --(CF.sub.2)n--COOH (n is zero or more integer). The resulting reaction mixture is processed by a mass spectrometer to obtain a mass spectrum to measure a mass of respective chemical species contained in the reaction mixture to determine an amino acid sequence of the protein or peptide from the carboxy-terminal.Type: GrantFiled: August 18, 1992Date of Patent: May 28, 1996Assignee: Seiko Instruments Inc.Inventors: Toyoaki Uchida, Akira Tsugita, Keiji Takamoto, Kazuo Satake

Patent number: 5439650Abstract: An reaction vessel utilizes a sample carrier composed of a magnetic core and a surface coating effective to support sample of protein or peptide. The sample carrier is floated magnetically and positioned within a reaction chamber. Edman reagent is applied to the sample to effect amino acid sequence analysis of protein or peptide from amino-terminal. By such construction, reaction efficiency is increased to produce sequentially thiazolinon amino-acid derivatives to thereby increase number of identified remaining amino acids, thereby enabling microanalysis of sample.Type: GrantFiled: November 3, 1992Date of Patent: August 8, 1995Assignees: Seiko Instruments Inc., Seiko Seiki Kabushiki KaishaInventors: Akira Tsugita, Masaharu Kamo, Toyoaki Uchida, Ikuo Nanno, Yasuhiro Nomoto, Seitaro Takahashi
