Patents by Inventor Shizuo Imaoka

Shizuo Imaoka has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8671625
    Abstract: The present invention provides a module structure and a plant construction method capable of easily attaching a facility device of a plant and shortening a plant construction period. The module structure of the present invention includes a support member which temporarily supports a facility device component to be arranged in a cell constituting a plant at a designed position and which constitutes scaffolding for attaching the facility device component and forming the cell, a box-shaped frame which is possible to be carried into inner space of the cell while fixing the support member, and joint means which is detachably attachable and which temporarily assembles the support member and the frame.

  • Patent number: 8524345
    Abstract: A temporary part is fixed to a base by using an adhesive layer to which fillers are mixed at a predetermined density. When the temporary part is heated, heat is applied to the fillers and the adhesive layer. At a temperature equal to or higher than the glass-transition temperature of the adhesive agent, the heated adhesive layer is thermally contracted so as to release remaining stress, and on the other hand, the heated fillers are thermally expanded. In this manner, the peel-off strength between the adhesive layer and the base (or the temporary part) is reduced, and the disassembly is facilitated.

  • Publication number: 20120037303
    Abstract: To ensure required adhesion even when a pipe of a piping module collides with a temporary material during transport and achieve easier dismantling, the following measure is taken: the temporary material is fixed on a support rack to prevent the piping module placed on the support rack from largely displaced during conveyance and after the conveyance of the piping module, the temporary material is removed from the support rack. In this method, the following measures are taken: at the step of fixing the temporary material to the support rack, the temporary material is bonded to the support rack with the piping module set therein using adhesive; and at the step of removing the temporary material from the support rack after the conveyance of the piping module, the temporary material bonded to the support rack with the adhesive is peeled off from the support rack with heat applied thereto.

  • Patent number: 7522026
    Abstract: New and useful alignment method and system for electromagnets used in the high energy accelerator that can make the installation simple and less time consuming are disclosed. By measuring the multiple of measurement reference points for obtaining the position and posture information of the electromagnet on the high energy accelerator, the deviation of the present value from the installation target value for the electromagnet within the reference coordinates in the building. For each of the adjustment mechanisms such as the multiple of adjustment bolts or the actuators, the Jacobian matrix representing the relationship between the unit operation amount and the posture changes of the electromagnet is obtained.
