Detecting apparatus, power receiving apparatus, power transmitting apparatus, and contactless power supply system

Abstract: There is provided a detecting apparatus including one or a plurality of magnetic coupling elements that include a plurality of coils, and a detector that measures an electrical parameter related to the one or plurality of magnetic coupling elements or to a circuit that at least includes the one or plurality of magnetic coupling elements, and determines from a change in the electrical parameter whether a foreign matter that generates heat due to magnetic flux is present. In the one or plurality of magnetic coupling elements, the plurality of coils are electrically connected such that magnetic flux produced from at least one or more of the plurality of coils and magnetic flux produced from remaining coils of the plurality of coils have approximately opposing orientations.

DeepBach: a Steerable Model for Bach Chorales Generation

Abstract: This paper introduces DeepBach, a graphical model aimed at modeling polyphonic music and specifically hymn-like pieces. We claim that, after being trained on the chorale harmonizations by Johann Sebastian Bach, our model is capable of generating highly convincing chorales in the style of Bach. DeepBach's strength comes from the use of pseudo-Gibbs sampling coupled with an adapted representation of musical data. This is in contrast with many automatic music composition approaches which tend to compose music sequentially. Our model is also steerable in the sense that a user can constrain the generation by imposing positional constraints such as notes, rhythms or cadences in the generated score. We also provide a plugin on top of the MuseScore music editor making the interaction with DeepBach easy to use.

Thin film semiconductor device for display

Abstract: An LDD structure of a thin film transistor for pixel switching is realized on a large glass substrate by low-temperature processes. A thin film semiconductor device for display comprises a display part and a peripheral driving part formed on a glass substrate (0). Pixel electrodes (9) and NchLDD-TFTs are arranged in a matrix in the display part. Thin film transistor PchTFTs and NchTFTs which constitute circuit elements are formed in the peripheral driving part. Each thin film transistor consists of a gate electrode (1), an insulating film (2) formed on the gate electrode (1), a polycrystalline semiconductor layer (3) formed on the insulating layer (2), and a high concentration impurity layer constituting a source (4) and a drain (7) formed on the polycrystalline semiconductor layer (3). Further, an NchLDD-TFT thin film transistor for switching has an LDD structure in which a low concentration impurity layer (8) is interposed between the polycrystalline semiconductor layer (3) and the high concentration impurity layer (7).

A high-performance short-channel bottom-contact OTFT and its application to AM-TN-LCD

Abstract: We have demonstrated an organic thin-film-transistor (OTFT)-driven active-matrix twisted-nematic liquid crystal display (AM-TN-LCD) on a glass substrate, with a resolution of 160/spl times/120 pixels, 79 ppi. Substrate temperature was kept below the plastic-compatible temperature of 180/spl deg/C throughout the fabrication process. In order to realize an OTFT-driven display with fine resolution, we employed short-channel bottom-contact (BC) pentacene OTFTs. It has been known that their drivability is limited by contact resistance at source/drain (S/D). We found that the S/D contact resistance was markedly reduced when the thickness of the nonohmic Ti adhesion layer for ohmic Au S/D electrodes was reduced less than /spl sim/3 nm. We elucidate that this 3 nm corresponds to the thickness of the accumulating layer in a pentacene channel. When we use a self-assembled monolayer of mercapto-silane-coupling agent as the adhesion layer, the contact resistance becomes negligibly small and BC OTFTs scalable below 10 /spl mu/m were obtained. In addition to this OTFT-cell technology, we developed a low-damage pentacene patterning technique for integration of OTFTs and introduced low-temperature panel assembly process to suppress thermal-stress degradation of pentacene OTFTs, which are the key technologies to achieve OTFT-driven AM-TN-LCD.
