Title: Liquid chromatograph-sampling device
Inventor: KOBAYASHI MASATO
IPC: G01N30/80
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To recognize the generation of blocking by providing a flow-rate detection means in a switchable second channel being provided on an analysis channel. SOLUTION: A sample solution that is subjected to constituent separation by a column 3 separately flows to an analysis channel 8 and a fraction collector channel 9 with a specific split ratio by a splitter 4. A sample solution flowing into the analysis channel 8 passes through a first channel 16 of a 6-port valve 15 and reaches a mass spectrometer 6, thus detecting a sample signal. In a certain amount of time, a switching valve in the fraction collector 7 is switched to sample a target constituent. For checking the blocked state during sampling, the 6-port valve 15 is switched to feed a solution for a mobile phase only. By measuring the rate of flow that actually runs by a flowmeter 17 at this time, the presence or absence of blocking can be verified. When no specific flow rate has been reached, failure can be easily determined by displaying an error on a display.

IPC: G03B13/34
Filed: 1984-03-19
Abstract: PURPOSE:To prevent a distance ring from rotating to a position which has passed through the initial position by inertia by placing a detaining claw working in the direction opposite to a ratchet by the same number of pieces as a lens barrel feeding cam, on the outside periphery of the distance ring, and engaging them at a position of the distance ring in case it is reset to the initial position. CONSTITUTION:In order to reset a lens barrel 2 to the initial position, the electric conduction of the forward direction is executed to a rotor 19 again, and a distance ring 1 is turned clockwise by a lens barrel driving operation.

Filed: 1992-03-10
Abstract: PURPOSE:To obtain a structure of the case of a printer wherein a cover is prevented from being disconnected when a paper is cut and noise caused by printing can be decreased without being accompanied with decrease in visibility. CONSTITUTION:As a fitting nail 6 on a printer cover A1 has an insertion structure, there exists no possibility of opening when a print paper 4 is cut in comparison with a printer with a rotating structure. In addition, a printer cover B2 is placed on the printer cover A1 and a sound absorbing material 3 is placed in the space and the printer cover B2 covers an outlet of the paper from a platen 5. In addition, noise is taken in the sound absorbing material 3 through a number of holes in a part 11 with a step 11 of the printer cover A1. An expansion type sound deadening room like this can decrease easily the noise of printing by making the cover into two bodies without enlarging the apparatus. In addition, visibility can be improved by taking the printer cover B for the purpose of improving visibility.
