Abstract: PURPOSE:To variously change coloring with a simple operation by freely expansibly and reducibly arranging a film, which has an expansion reversibility and shows the optical anisotropy of a fixed direction at the time of expansion or contraction, between two polarizing films facing each other. CONSTITUTION:A gap part 11 slightly wider than the thickness for contraction of an elastic anisotropic film 3 is provided between polarizing films 1 facing each other, and upper end parts of polarizing films 1 are connected by a connection part 12. An expanding/contracting device 2 is attached to lower end faces of polarizing films 1 without closing an aperture part 13. The elastic anisotropic film 3 has expansion reversibility and has molecules arranged in a fixed direction in accordance with the degree of expansion or contraction to show the optical anisotropy. Consequently, the appearance of various colors, the change of hue and decoloring are simultaneously realized by the easy operation which controls expansion and contraction of the elastic anisotropic film 3. Thus, the light of user's desired color can be obtained, since coloring is variously changed.

Abstract: PURPOSE:To obtain an extra-fine semiconductor quantum box without causing damages in process by a method wherein, on the surface of a substrate crystal slanting to a predetermined azimuth from the crystal face, at least two types of semiconductors which are formed corresponding to the raw atoms or raw compounds of the substrate crystal are applied to lines along an atomic step one atom by one atom. CONSTITUTION:A substrate crystal, i.e., a GaAs substrate 1, which, for instance, slants from the [110] azimuth of the GaAs (001) face by an angle theta=5 deg. and from the vertical azimuth [110] in the GaAs face by an angle phi=1 deg. is employed. Raw aluminum or raw gallium obtained by thermal decomposition in gas is preferentially applied to the kink 6 position on a terrace 5 to induce linear crystal growth shown by an arrow to [110] direction. Once the growth reaches the end of the terrace 5, the crystal growth id started again from the adjoining kink site. Before the whole surface of the terrace is covered, the raw material is switched from aluminum to gallium so as to have a part of the terrace 5 covered with GaAs 31 and the other part of the terrace 5 covered with AlAs21. Such crystal growth is repeated several times to form a GaAs quantum box 32.

IPC: B65G65/30
Filed: 1998-10-15
Abstract: PROBLEM TO BE SOLVED: To prevent granular material remaining on a long-distance conveyor from disturbing level control at a receiving hopper. SOLUTION: A sum of a granular material amount on a conveyor 3 having a long transport distance, and a granular material amount in a receiving hopper 4 is regarded as a granular material amount in the receiving hopper 4 for controlling a delivery amount to the conveyor 3, thereby keeping the weight of granular material constant via a system including a conveyor 3 having a long transport distance and the receiving hopper 4. As a result, an independent level fluctuation at the receiving conveyor 4 can be restrained to a minimum and coal is stably fed from the receiving hopper 4 to a coal mill 5, and the operation of the coal mill 5 is stabilized. At the same time, the stop and re-start operation of the conveyor due to the fluctuation of a coal level at the receiving hopper 4 is lessened, and a mechanical load on a conveyor drive device is lessened as well.

When the added amount is larger than the transaction limit amount, a customer A is requested by a retail store owner B to input his password number. When the customer A inputs his password number (S18), the number is collated with a stored password number (S19). If the added amount is smaller than the transaction limit mount, the transaction amount total information is updated to an amount decided with addition of the transaction amount total information (S23). When it's decided that a transaction is possible with use of a customer card, the display is performed for confirmation and the customer's operation is guided. When the owner B confirms the transaction (S26), the relevant commodity is given to the customer A and the customer A pulls out his card (S28).
