Filed: 1994-06-07
Abstract: PURPOSE:To easily form a top board without rounding each corner of the top board body, by forming a recess having a shape such that it is cut wall- thicknesswise from the outer surface of in edge member, in the rear edge side of the edge member. CONSTITUTION:A recess 231 having a cut-in shape is formed in the rear edge side outer surface of a side edge member 23 laid along each of the left and right side edges of a top board body 1, being integrally formed with the side edge member 23 during resin molding. When the side edge makes contact with a wall or top boards are make contact with each other through their side edges, the recess 231 defines an opening which is used as a relief for a wiring laid cover a desk or a table, and for clamps with which a stand is installed. Accordingly, it is possible to eliminate the necessity of rounding each of the corners of a top board core 11, an outer surface decorating panel 12 and a rear surface decorating panel 13. Since the top board can be easily formed without increasing the number of process steps, and further since cutting an extrusion molding article to a predetermined length, can be simply made along the recess 231 so as to form the top board, the process can be simplified.

Title: Forming method for donor-doped perovskite material for thin film dielectric material and structure containing such material
Inventor: SUKOTSUTO AARU SAMAAFUERUTO
IPC: C30B31/00
Filed: 1993-05-28
Abstract: PURPOSE: To maximize the permittivity of a thin-film perovskite material by performing the doping of the perovskite material, without keeping a board at high temperature. CONSTITUTION: The permittivity of a perovskite material becomes higher under its Curie temperature accordingly, as its crystal grain size becomes smaller. A donar dopant makes the crystal grain size of the perovskite material smaller. Accordingly, as a result of performing the doping of an intrinsic perovskite material with donar dopants and then forming a donor-doped perovskite material layer, having average grain size smaller than its intrinsic critical crystal grain size, the permittivity of this layer is mage higher than that of the intrinsic material which has an average crystal grain size similar to the average crystal grain size of this layer. It is preferable that doping with acceptor dopants be performed, in addition to making the resistance of this material higher and/or to make its dielectric tangent smaller.  The construction on the board surface comprizes a conductive layer and the layer of this donor-doped perovskite material which is in touch with this.

Abstract: PURPOSE:To enable unidirectional rotation by arranging a plurality of asymmetric-shaped pole teeth mutually facing alternaterly in the circumferential direction and changing over the direction of currents flowing through an exciting coil in response to the angle of rotation of a rotor. CONSTITUTION:A pole tooth 5 attracts the S pole of a rotor magnet 1 and a pole tooth 6 the N pole of the rotor magnet 1 respectively under the state of excitation in which currents are made to flow through an exciting coil 8, and the rotor magnet 1 is moved forward in the direction of the arrow in the figure. When the rotor magnet 1 is advanced and the borderline of the pole and pole of the rotor magnet 1 reaches the position of a sensor 7, the sensor 7 also does not output a signal to a transistor because the sensor 7 does not receive magnetic flux from the rotor magnet 1, thus bringing the coil to the state of non-excitation, then forward moving the rotor magnet 1 up to a stabi lized position having minimum magnetic resistance in the right direction. The sensor 7 detects the S pole of the rotor magnet, and a stator 4 and the pole tooth 5 are excited in the N pole and one stator 4V' and the pole tooth 6 in the S pole. Accordingly, force works to a rotor, and the rotor magnet 1 is advanced in the direction of the arrow on the right side.
