  • Patent number: 10411617
    Abstract: A dielectric elastomer motor includes an artificial muscle and a conversion mechanism cooperating with the artificial muscle. The artificial muscle includes a dielectric elastomer film or layer having a first surface and a second surface opposite to the first surface. First and second electrodes are attached to the first surface and the second surface of the dielectric elastomer film, respectively. First and second bases are attached to the dielectric elastomer so as to be spaced apart from each other. The first base and the second base are capable of reciprocation relative to each other upon change in size of the dielectric elastomer. The conversion mechanism converts the reciprocation of the bases to pivotal or rotational movement. The dielectric elastomer receives voltage application with a predetermined timing via the first and the second electrodes.

  • Publication number: 20170271080
    Abstract: To provide a method for forming a boron-containing thin film, by which a uniform boron thin film with good adhesion can be formed on the surface of a processing object, and also to provide a multilayer structure. An electrolysis apparatus includes an anode 1, a processing object 2 serving as a cathode, an electrolytic vessel 4, and a molten salt electrolytic bath 5. A variable power supply 6 is connected between the anode 1 and the processing object 2. The variable power supply 6 is configured to be capable of changing a voltage or current waveform during the electrolysis process. Current of an appropriate pulse waveform is applied in the molten salt for electrolysis to form a uniform boron thin film 3 within the processing object 2 having a complicated shape.

  • Publication number: 20170155032
    Abstract: A dielectric elastomer driving mechanism includes a driver, a follower, and a power transmitter. The driver includes a dielectric elastomer driving element made up of a dielectric elastomer layer and two electrode layers sandwiching the dielectric elastomer layer. The driver also includes a tension maintaining element maintaining, in a no-voltage state, the dielectric elastomer driving element in a state in which tension occurs, and includes an output portion capable of moving along with the expanding or contracting of the dielectric elastomer driving element. The follower includes a following element actuating in accordance with a driving force inputted. The power transmitter is connected to the output portion of the driver for transmitting a driving force of the driver to the follower.
