Title: Glow discharge spectrometry
Inventor: RONAN GERARD A
IPC: G01N27/62
Filed: 1991-01-10
Abstract: Abstract The invention provides glow discharge optical or mass spectrometers wherein a solid sample may be mounted in a unitary source assembly adjacent to a first electrode means. A second electrode means, spaced from sample by an insulating washer, is also part of the source assembly and engages with a discharge chamber into which a discharge gas is introduced. A glow discharge is maintained in the discharge chamber by a potential difference applied between the first and second electrode means. In a mass spectrometer, ions formed in the discharge pass to a mass analyzer, while in an optical spectrometer, optical radiation from the discharge is spectroscopically analyzed. Particularly in the case of a mass spectrometer, the source assembly may be mounted on an insertion probe allowing it to be easily withdrawn from the vacuum envelope to facilitate sample changing and maintenance.

Abstract: In a key telephone  system in which a plurality of data terminals 371 ... 37n such as personal computers are connected to a key service unit 1 connected to a plurality of telephone lines 251 ... 25m, a modem 43 is pooled so as to be usable in common for the plural data terminals 371  ...  37n.   In response to a called party number  signal  from the  telephone  lines  (e.g.  251)  in dial-in service, the key service unit 1 selects a single data  terminal  designated  by  an  extension  telephone designation signal in dial-in service from among the data terminals 371 ... 37n, and closes a communication channel between the selected data terminal  (e.g.  371)  and the modem 43, so that a status equivalent to that where the selected data terminal 371 and the modem 43 are directly connected to each other can be established.  Thereafter, the key service unit 1 indicates a called party number signal  reception  to  the  modem  43,  and  the  modem  43 transmits a call to the selected data terminal 371.  When the selected data terminal 371 responds to the call from this  modem  43,  the  key service  unit  1  closes  a communication  channel  between  the  modem  43  and  the telephone line 251, so that a communication link between the selected data terminal 371 and the telephone line 251 can be established via the modem 43.  During the process until this communication link can be established, since the selected data terminal 371 and the modem 43 are in the status equivalent to direct coupling, the key service unit 1 is not concerned in the communications between the selected  data  terminal  371  and  thus  modem  43,  thus reducing the operational load applied to the key service unit 1.

Filed: 1992-02-13
Abstract: ABSTRACT OF THE DISCLOSURE    The sampling valve of the invention comprises two fixed elements having penetration holes, and a movable element having at least one penetration hole being held movably between these fixed elements, and functions to distribute a liquid specimen such as blood in slices, and determine quantitatively, sample and transfer it, and is used in an automatic analyzing apparatus such as blood analyzer.    In this sampling valve, a liquid chamber (27) for covering the outer circumference of the sliding surfaces of the movable element and fixed elements is formed, and a wedge-shaped slope (15) is formed at the outer end portion of the sliding surfaces.  The liquid chamber (27) is composed of an enclosure (24) for covering the outer circumference of the movable element.  An arm (28) coupled to a driving source (21) is joined to the movable element so as to be movable within the opening (25) of the enclosure (24), thereby composing so that the valve may be changed over easily.    In this way, the lubricating effect of the sliding surfaces of the movable element and fixed elements may be enhanced and sticking may be prevented, while it is possible to change over with a small force.
