  • Patent number: 10157758
    Abstract: Provided are a work heating device which is capable of heating a work piece with high soaking properties as well as fine temperature control and which remains highly reliable over a long-term use by preventing the deformation or the like of a chuck member, and a work treating device that uses the work heating device. The work heating device is a work heating device in which the chuck member including a work attraction electrode for work attraction and a heater member including a heating element for work heating are layered, and which is capable of heating with the heater member the work piece stuck by attraction on the chuck member side, in which the heater member includes a chuck attraction electrode for causing the chuck member to stick by attraction, between a surface of the heater member that is opposed to the chuck member and the heating element, so that the chuck member and the heater member are layered detachably.

  • Patent number: 9634582
    Abstract: Provided is a detachable generator device which can change the installation location with ease and which can effectively use a solar cell to generate electric power. The detachable generator device includes: a film-like solar cell; and attaching/detaching means for allowing the film-like solar cell to be attached to and detached from an attachment object at an installation location. The attaching/detaching means includes an adhesive film having an attaching/detaching surface which develops Van der Waals force to enable repeated affixation, or an electrostatic chuck for forming an attaching/detaching surface by turning on/off a voltage source connected to an attraction electrode sandwiched between two insulating layers to freely develop electrostatic attraction on a surface of at least one of the insulating layers.

  • Publication number: 20120120545
    Abstract: Provided are an electrostatic attracting structure which allows a strongly integrated structure to be maintained when used, and also allows the structure to be changed freely in configuration after the use, and a method of fabricating the same. The electrostatic attracting structure includes: a plurality of sheet members each having an electrode which is sandwiched between two dielectric materials; and at least one attraction power source, in which the plurality of sheet members are stacked, and by applying a voltage between the electrodes of facing sheet members, the facing sheet members are electrically attracted and fixed, when the electrostatic attracting structure is used, the dielectric material of any one of or both of outermost sheet members attracts the object to be attracted, and after the use, the stacked plurality of sheet members are made separable from one another by canceling the application of the voltage.
