Abstract: A casing (25) and a nozzle plate (27) form a hollow cavity in which ink liquid can be filled. A buckling structure body (21) is disposed within this hollow cavity. A nozzle orifice (27a) is provided in a nozzle plate (27) at a position corresponding to the buckling structure body (21). The buckling structure body (21) has a portion extending in a longitudinal direction (in the direction of arrow D2). Both ends of the buckling structure body (21) in the longitudinal direction are fixedly attached to the casing (25) via an insulative member (23). The buckling structure body (21) is formed of a material that is displaced at least in the longitudinal direction by conduction of current from a power source (29). Thus, an ink jet head of a long lifetime is provided that can provide a great discharge force while maintaining its small dimension.

Abstract: A cartridge provided with a case for housing an optical disk so that it can be driven and rotated. A recessed section is formed around the peripheral edge of the center hole of the optical disk. A hub, which is used for clamping the optical disk by the use of a magnetic force, is formed into a hat-shape, and it is placed at the recessed section. The height of the hub is set to be greater than the gap between the optical disk and the cartridge case. Without the necessity of fixing the hub to the disk, this arrangement makes it possible to prevent the hub from coming off from the recessed section. Thus, the arrangement eliminates the fixing process between the hub and the optical disk as well as maintaining the clamping function of the hub, thereby making it possible to reduce the manufacturing cost.

Abstract: PROBLEM TO BE SOLVED: To provide an apparatus for manufacturing a crystal sheet, with high productivity. SOLUTION: A plurality of holding parts 17 are provided at a predetermined interval on the outer periphery of a rotation body 2. A loading rotation body 14 is arranged at one side of the rotation body 2. Further, a withdrawing rotation body 15 is arranged at the other side of the rotation body 2. The opening of a loading guide 16, provided at the loading rotation body 14, is installed opposed to one opening in the axial direction of the holding part 17, and the opening of a withdrawing guide 18, provided at the withdrawing rotation body 15, is installed opposed to the other opening in the axial direction of the holding part 17. In this state, the rotation body 2, the loading rotation body 14 and the withdrawing rotation body 15 are synchronously rotated, and thereby, a forming substrate 3 is guided to the holding part 17 by the loading guide 16.

Abstract: PROBLEM TO BE SOLVED: To provide a device and a method for manufacturing a crystalline sheet in which the reliability and productivity to the manufacture of the crystalline sheet such as a silicon sheet are improved, the heat loss is minimized as much as possible, and the manufacturing cost is reduced. SOLUTION: A holder 5 with immersion members disposed on an outer circumferential surface is disposed in a rotational and slidable manner in at least one recess of an outer circumferential surface of a rotating body 3, at least one heat insulation chamber 29 constituted of the outer circumferential surface of the rotating body 3 and a partition member 4 is provided, only the immersion step in the holder 5 is performed in one heat insulation chamber 29c, and the holder 5 is fed or taken out in another heat insulation chamber. The immersion step, the feeding step, the taking-out step, etc., are performed by the rotation of the rotating body 3 independently and parallel to each other.

Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for manufacturing a crystal sheet improving a productivity of the crystal sheet having a uniform sheet thickness and a uniform surface coarseness and at the same time having a small heat loss within the main body of the apparatus. SOLUTION: It is able to suppress heating power by preventing a heat loss and reducing the change of the temperature within the main body of the apparatus by arranging rotating bodies 2, each having a plurality of base members 8 disposed around the outer periphery of it, within a plurality of compartments 19-20 thermally insulated with insulating members 13, 14. It is also able to extremely improve productivity by eliminating factors of lowering efficiencies by performing the operations in the plurality of the compartments independently and in parallel and by separating the peeling operation, which has been the most disturbing matter of the productivity, from the main body of the apparatus. It is also able to manufacture a high quality crystal sheet by performing the sheet producing operation without influence of a shock accompanied with the peeling operation and without an irregularity of the melt surface.

Abstract: PROBLEM TO BE SOLVED: To make portable equipment for audio, etc., thinner. SOLUTION: Circuit boards 19a and 19b are made thinner at some parts (coupling substrate 20) than at other parts and components which determine the thickness of a feed motor 12, etc., are arranged so as to overlap them with the parts 20 of the boards which are made thinner. When flexible substrates are used as the coupling substrates, the thickness can be made specially less. Further, a multi-layered printed board may be used and formed in a single layer or a less number of layers at the part than at other parts.
