摘要:
An apparatus is provided for the heat treatment of polyolefin resin particles. The apparatus is equipped with an autoclave in which the particles are heated and agitated in the presence of an aqueous medium and dispersing agent. The autoclave has a tilted bottom wall portion, over which an impeller, preferably, a turbine-type impeller is provided.

Prefoamed particles of a polyolefin resin are produced by dispersing starting particles of the polyolefin resin, which contains a volatile foaming agent, in a dispersant in a pressure vessel, heating the resultant dispersion to a temperature of at least the softening point of the starting particles in said pressure vessel and then opening the vessel at one end thereof so as to release the starting particles and dispersant into an atmosphere of a pressure lower than the internal pressure of the vessel. The release of the starting particles and dispersant is performed while feeding a heating liquid.
摘要:
A method for pressurizing pre-foamed particles of a polyolefin resin by maintaining the pre-foamed particles in an atmosphere of a pressurized gas to impart a predetermined internal pressure thereto, which comprises first maintaining the particles under a pressure which does not cause shrinkage to the particles, and then increasing the applied pressure gradually under conditions which do not cause shrinkage to the particles.

Image forming apparatus (100) creates a toner pattern on intermediate transfer belt (11) as a preprocessing of gradation correction, and calculates a cycle at which density unevenness is largest. Then, a toner image for gradation correction is formed so as to cancel cyclic unevenness at a cycle at which the largest density unevenness occurs. As a result of this, it becomes possible to suppress the deterioration of density detection accuracy and perform a highly accurate gradation correction even if density unevenness of any cycle occurs.

Provided are an image forming apparatus and an image forming method capable of easily forming an output image having desired gradation characteristics and capable of reducing running cost. In an intermediate transfer-type image forming apparatus, an image forming section is configured by including a first image forming section which forms a color toner image on a photoconductor, and a second image forming section which is located on the upstream side of the first image forming section and forms a transparent toner image on the photoconductor. Further, after the transparent toner image is formed on an intermediate transfer member by the second image forming section, the first image forming section forms, on the basis of image data (correction gradation values) corrected by a gradation correcting section, a color toner image so that the color toner image is superimposed on the transparent toner image.

The process for manufacturing a platinum temperature-measuring resistance element comprises the step of preparing a thermosensitive part having a portion to be sealed coated with a glaze; the step of placing a pre-sealing element on a tray and inserting the same in a chamber; the step of enclosing a purge gas containing an inert gas and oxygen in the chamber; the step of raising the internal temperature of the chamber to a region in which the platinum is in reduced form at a partial pressure of oxygen in the purge gas as determined from platinum oxide formation free energy; the step of replacing the purge gas with an inert gas wherein oxygen is 1 kPa or below; and the step of under the replaced condition, rapidly heating the furnace interior (interior of the chamber) to a fit melting temperature by means of a lamp heating unit to thereby seal the portion to be sealed of the thermosensitive part.

An elevator group control system includes a reference route generating portion, which for each elevator, generates a reference route which the elevator should follow with respect to the time axis and position axis; and an assignment portion which selects an elevator for assignment to a generated hall call so as to make the actual trajectory of each elevator closer to its reference route. Reference routes which guide the cage's trajectory into temporally equal interval condition are generated, and car assignment is executed to allow the cages to settle in temporally equal interval condition over a long period of time.
