The second chamber is variably controlled from the medium vacuum state to a high vacuum state.

Abstract: A bonding apparatus, suitable for accurately bonding large substrates for a liquid crystal display, includes Z-axis drive mechanisms, and upper and lower chambers. The Z-axis drive mechanisms for moving an upper frame vertically are disposed at four corners of a mount. The upper chamber is supported by the upper frame and has an upper table inside. The lower chamber has a lower table inside and is supported on the mount. The upper and lower chambers are united through a seal ring to define a vacuum chamber. Moving the upper frame moves the upper chamber vertically to open or close the vacuum chamber. The lower table is supported via a free joint stage between the plurality of support legs and the table, and is moved horizontally by a side thrust mechanism disposed outside of the vacuum chamber.

Abstract: Magnetic toner involves magnetic powder 1 having the particle shape of an octahedron 2 that is a convex polyhedron surrounded by eight triangles as a basis, each of the vertexes and edges of the octahedron being in a curved surface shape, and having a portion 3 that can be taken as a straight line on the outer periphery of its projected image. Therefore, the magnetic toner is superior in both two contradictory properties, that is the property of making it easy for a charging amount to quickly rise as well as improving the charging amount and the property of making it difficult for charge-up to occur, thereby making it possible to form a good image under a wide environment. In an image forming method, an electrostatic latent image is developed into a toner image by a magnetic one-component jumping developing method using the magnetic toner.
