Abstract:
The invention provides a method of manufacturing a semiconductor device, capable of enhancing characteristics of each semiconductor element constituting the semiconductor device, while reducing or suppressing non-uniformity in the characteristics thereof. When forming a thin-film circuit constructed by arranging a plurality of pixel circuits on a glass substrate, first, a plurality of concave portions to be seeds in crystallizing a semiconductor film are formed on the glass substrate with a pitch n times an array pitch of a plurality of pixel circuits. Then, an amorphous silicon film is formed on the glass substrate on which the concave portions are formed, and by crystallizing the silicon film by heating, a substantially monocrystalline silicon film is formed within a region centered on the concave portions. Using each of the substantially monocrystalline silicon film formed substantially centered around the respective concave portions, pixel circuits are formed.

An electronic paper printer 1 has a describing head 3 for describing display patterns on electronic paper 2 capable of having display patterns rewritten thereto and erased therefrom, using electrophoresis, an erasing head 4 for erasing display patterns described on the electronic paper 2, a drive mechanism (not shown) for driving the describing head 3 and the erasing head 4 so that they turn, and a conveyor mechanism (not shown) for conveying the electronic paper 2. The describing head 3 is configured by a pair of drums 31 and 32 supported so that they freely turn. The erasing head 4 is configured by a pair of drums 41 and 42 supported so that they freely turn.
Abstract:
A plurality of strings are stretched over a frame, constituting an overall framework of a body of a piano, with their respective rear-end engaging rings engaged by corresponding pins provided on the frame. There is also provided a string-bounding preventing member that, in case any one of the strings snaps or breaks, prevents the broken string from disengaging from the corresponding pin to bound violently away from the pin. The string-bounding preventing member is, for example, a strap member that is passed through the respective engaging rings to thereby connect together the strings. The string-bounding preventing member allows the broken string to be left connected with the other strings and hence stay in place on the frame without bounding.

Abstract:
A thin film device fabrication method in which a thin film device formed on a substrate are transferred to a primary destination-of-transfer part and then the thin film device is transferred to a secondary destination-of-transfer part. A first separation layer (120) made of such a material as amorphous silicon is provided on a substrate (100) which allows passage of laser. A thin film device (140) such as TFTs are formed on the substrate (100). Further, a second separation layer (160) such as a hot-melt adhesive layer is formed on the thin film devices (140), and a primary destination-of-transfer part (180) is mounted thereon. The bonding strength of the first separation layer is weakened by irradiation with light, and the substrate (100) is removed. Thus, the thin film device (140) is transferred to the primary destination-of-transfer part. Then, a secondary destination-of-transfer part (200) is attached onto the bottom of an exposed part of the thin film device (140) via an adhesive layer (190). Thereafter, the bonding strength of the second separation layer is weakened by such means as thermal fusion, and the primary destination-of-transfer part is removed. In this manner, the thin film device (140) can be transferred to the secondary destination-of-transfer part (200) while maintaining layering relationship with respect to the substrate (100).
