  • Patent number: 10563093
    Abstract: [Object] To provide a polysilazane-containing composition for forming a film. In order to form a dense and processable siliceous film, the composition is intended to be employed in a two-step conversion process comprising the steps of: forming a film having a dry surface from the composition provided that the conversion in to the siliceous substance proceeds insufficiently; and then subjecting the film to secondary processing. [Means] The present invention provides a polysilazane-containing film-forming composition comprising a particular amine compound, a polysilazane compound, and a solvent; and the invention also provides a process for forming a siliceous substance. In the process, the composition is applied to coat a substrate and thereafter converted into the siliceous substance. The particular amine compound has two amine groups, and the amine groups have at least one phenyl-substituted hydrocarbon group.

  • Publication number: 20090180021
    Abstract: A lens unit and a sensor unit are held by a lens holding mechanism and a sensor shift mechanism. As the sensor unit is moved in a Z axis direction on a second slide stage, a chart image is captured with an image sensor through a taking lens so as to obtain in-focus coordinate values in at least five imaging positions on an imaging surface. An approximate imaging plane is calculated from the relative position of plural evaluation points which are defined by transforming the in-focus coordinate value of each imaging position in a three dimensional coordinate system. The second slide stage and a biaxial rotation stage adjust the position and tilt of the sensor unit so that the imaging surface overlaps with the approximate imaging plane.

  • Patent number: 5099734
    Abstract: A slitter slits a wide web into narrow strips by at least one slitting blade mounted on a shaft member which extends in the transverse direction of the wide web while the wide web is fed in the longitudinal direction thereof. The slitter is provided with a slitting width changing system which has a slitting blade holder which holds the slitting blade and is fitted on the shaft member to be rotatable about the shaft member between a released position in which it can be slid along the shaft member in the longitudinal direction of the shaft member and a locked position in which it is fixed to the shaft member not to slide along the shaft member. A slitting blade shift mechanism rotates the slitting blade holder to the released position, slides it along the shaft member to a position determined according to a desired slitting width, and rotates it to the locked position.

  • Patent number: 4972743
    Abstract: An apparatus for feeding sheets comprises a variable speed conveyor for feeding a sheet cut from a web. A high speed conveyor receives the sheet fed by the variable speed conveyor, and feeds it at a high speed v1. A cutting completion detector detects the separation of the sheet from a cutter and generates a detection signal. A controller adjusts the feeding speed of the variable speed conveyor to a feed speed v2 as long as the leading portion of the web is being fed to the cutter, adjusts the feeding speed to a speed v0 (v0<v1, v2), at which the sheet is kept stationary with respect to the cutter, during the time from when the cutter starts cutting the web to when the cutting is finished and the cut sheet separates from the cutter, and increases the feeding speed from the speed v0 to the speed v1 during the time from when the detection signal is generated to when the sheet arrives at the high speed conveyor.
