The sample vaporization chamber (1) for a gas chromatograph has a housing (2) with a built-in heater (12). An opening (18) sealed by a septum (20) is provided on the upper surface of the housing (2). The sample injected into the internal space (3) of the housing (2) by a syringe needle that penetrates the septum (20) and is inserted into the internal space (3) of the housing (2) through the opening (18) is heated by the heater (12) and vaporized to generate sample gas. The sample vaporization chamber has a cylindrical liner (16) at least at the lower end. The inner or outer circumferential surface is provided with a first thread (26); and a liner fixing part (4) is provided in the internal space (3) of the housing (2) and has a second thread that is threadedly engaged with the first thread (26) of the liner (16), for fixing the liner (16) in the state of being housed in the internal space (3) of the housing (2) by threading the first thread (26) of the liner (16) inserted from the opening (18) into the internal space (3) with the second thread.

This invention relates to the field of flue gas dust removal and discloses a flue gas dust removal device for lime rotary kiln calcination, comprising: a first dust removal cylinder, a second dust removal cylinder disposed at one end of the first dust removal cylinder, and a switching gap between the first and second dust removal cylinders for switching the dust removal core; a cleaning structure disposed inside the first dust removal cylinder for cleaning the inner wall of the first dust removal cylinder; by setting up a driving structure, a switching structure, and two switching cylinders, when it is necessary to replace or clean the dust removal core in one of the switching cylinders, the driving switching structure drives the switching mechanism to switch out the corresponding switching cylinder and the dust removal core, while at the same time, the other switching cylinder and the dust removal core are switched to the flue gas treatment position. In this way, when cleaning or replacing the corresponding dust removal core, the other dust removal core can continue to perform dust removal work, making the operation simpler and more convenient, and the dust removal efficiency higher.

This invention addresses water purifiers installed in low positions, such as under a sink, providing a water purifier that allows operators to easily and effortlessly perform tasks such as changing the water filter cartridge. The water purifier of this invention features an inclined holding structure that holds a cylindrical water filter cartridge, which is installed and removed by insertion and removal along its axial direction, in a position with a predetermined inclination angle relative to the horizontal (less than vertical) while water is flowing through it. This allows operators to easily change the water filter cartridge from a low position. Furthermore, the water purifier of this invention is characterized in that the predetermined inclination angle is a downward inclination towards the vertical direction in which the water filter cartridge is inserted and installed.

This invention provides a cutting device capable of automatically changing plates. A cutting device for cutting a workpiece using a cutting tool includes: a chuck table for holding a plate with grooves formed by the cutting tool; a cutting unit having a spindle and a mounting flange fixed to the front end of the spindle for mounting the cutting tool; and a changing device for changing the cutting tool mounted on the mounting flange and stored in a tool storage section, and for changing the plate placed on the chuck table and stored in the plate storage section. The changing device has a holding section for attracting and holding the cutting tool and the plate, the holding section having: a tool attraction pad that contacts the cutting tool or a base for fixing the cutting tool to attract and hold the cutting tool; and a plate support section that protrudes outward from the front end of the tool attraction pad to support the plate.
