A material processing apparatus is disclosed. This material processing apparatus is particularly developed to utilize a quasi-traveling microwave to conduct heat treatment for a thread-type article like fiber, silk, artificial fiber, and artificial silk. The material processing apparatus comprises a primary waveguide tube, a microwave blocking plate, a secondary waveguide tube, and at least one microwave absorbing member disposed of in the primary waveguide tube. By such design, a microwave source supplies a microwave to the secondary waveguide tube and the primary waveguide tube, such that the microwave travels in the two waveguide tubes so as to become a quasi-traveling microwave. Therefore, in the case of a thread-type article being be fed into the primary waveguide tube via the secondary waveguide tube by a thread-type article transferring mechanism, the thread-type article is steadily and evenly heated by the quasi-traveling microwave in the two waveguide tubes.

Material processing apparatus using quasi-traveling microwave to conduct heat treatment

The present invention proposes an electrode thin film and a method for manufacturing the electrode thin film. The method includes: determining a height between a first roller and a substrate and a coating speed for the first roller coating a first metal nanowire suspension liquid onto the substrate based on a suspension property of the first metal nanowire suspension liquid; coating, by using the first roller, the first metal nanowire suspension liquid onto the substrate with the coating speed to form a wetting film on the substrate; and controlling a first temperature of the substrate heating the wetting film based on the suspension property of the first metal nanowire suspension liquid to dry the wetting film as the electrode thin film. The first temperature makes a dewetting speed of the wetting film higher than a drying speed of the wetting film.

A measuring apparatus for electromagnetic property of material includes a chamber and a specified shielding piece. The chamber has a cavity inside and the chamber has an electromagnetic wave access terminal to connect to the cavity, used to receive an input electromagnetic wave and output a reflective electromagnetic wave. The specified shielding piece is disposed inside the cavity with respect to the electromagnetic wave access terminal, used to produce a region in side the cavity. The region is dominated by magnetic field and is used to adapt an object to be measured.

Disclosed is a 3-dimension non-bias electrets multi-touch device, comprising a first electrets thin film providing a first bias electric charge to form an electrostatic field, a first electrode, a second electrode and a controller. The first electrode is attached to the first electrets thin film and outputs a first signal when the electrostatic field is changed by a deformation of the first electrets thin film due to contact pressures of external forces. The second electrode outputs a second signal when the electrostatic field is changed. The first and second electrodes transmit the first and second signals to the controller. The controller is capable to detect and analyze positions where the contact pressures of the external forces are applied and normal vector shifts of the first electrets thin film at the positions.
