Abstract:
ABSTRACT To provide a technology for obtaining a probe carrier which is quality assured by an effective inspection program and an effective producing steps. Quality of a produced probe carrier is ensured by expanding test items in the processes from synthesis and purification of the probe to fixation thereof to a carrier.
Abstract:
By employing a sleeve piston construction, it is possible for a piston-type air pump (a compressor or a vacuum pump) to have a number of compression stages in one cylinder and for a piston-type fluid pump to continuously pump out fluid by means of a single small piston during reciprocating motion, unlike a case where differential and double-acting constructions are employed. Moreover, by using a driving system of electromagnetic and rotator-piston types, it is possible to attain a small-volume, large-compression-ratio (in the case of a compressor and a vacuum pump) and leakage-free piston pump.
Abstract:
To provide a beverage dispenser capable of appropriately and smoothly supplying a supercooled beverage. [Solving Means] The present invention provides a beverage dispenser 1 which supplies a beverage brought into a supercooled state at a solidifying point or less and which releases the supercooled state in the outside, and the beverage dispenser includes a primary cooling device 13 which cools the beverage to an ice point or so, a beverage supply circuit 7 which supplies the beverage cooled by the primary cooling device 13 to the outside, a brine circuit 31 through which an antifreezing liquid cooled to the solidifying point or less of the beverage is circulated, and a heat exchanger 16 for supercooling the beverage, which performs heat exchange between the beverage flowing through the beverage supply circuit 7 and the antifreezing liquid flowing through the brine circuit 31.
Abstract:
There is disclosed a beverage dispenser capable of appropriately and smoothly supplying a supercooled beverage without being influenced by a type of raw water. The present invention is a beverage dispenser 1 comprising: a raw water treatment device 63 which deaerates raw water and/or filters the raw water through a reverse osmosis film; a primary cooling device 13 which cools said raw water to an ice point or so; a raw water supply circuit 59 which supplies the raw water cooled by the primary cooling device 13 to the outside; a secondary cooling device 30 which cools the raw water flowing through the raw water supply circuit 59 into the supercooled state at the solidifying point or less; and a syrup circuit 53 which supplies a syrup to the raw water supplied to the outside through a heat exchanger 61 for supercooling the raw water of the secondary cooling device 30.
Abstract:
A radio communications system which makes communications on a vacant channel selected from a plurality of frequency channels, and wherein a calling station sends a station discrimination code to specify a remote station together with vacant channel data that enables communication, and the remote station specified by the station discrimination code is shifted to the specified vacant channel thereby to make communication between the two stations. When the channel on which the two stations are communicating is busy, and when it is desired to use another channel, one station sends the date for another channel on the channel on which the communications are made, and the other station receives the data and continues the communications on the other channel.
Abstract:
The present invention relates to an information acquisition method of acquiring information of distribution of a protein or peptide in a sample based on mass information obtained by mass spectrometry of the protein or peptide. The method includes mass spectrometry of a definite region of the sample after limited proteolysis of the protein or peptide and acquisition of information relating to distribution using an ion peak that has a two-dimensional intensity distribution having a Pearson product-moment correlation coefficient of 0.5 to more and 1.0 or less in the definite region against the two-dimensional intensity distribution of the parent ion of the protein or the peptide subjected to the limited proteolysis and has a peak intensity ratio of larger than 1.0 against the peak intensity of the integrated spectrum of the parent ion in the definite region, wherein the m/z of the ion peak is greater than 500.
Abstract:
The problem to be solved by the present invention is to provide a method for treating a polypeptide including a cysteine residue for enhancing the sensitivity of detection thereof in mass spectrometry using charged particles. A mass spectrometry method for a polypeptide including a cysteine residue is provided which includes treating the polypeptide including a cysteine residue with a cyanation agent, treating the cyanated polypeptide with a base, and then desorption ionizing the base-treated polypeptides using charged particles for mass spectrometry.
