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: The deformable mirror (10) includes a first carrier plate (4) with a first reference surface (4a) which can provide a first degree of spherical aberration to incident light. The mirror has a second transparent carrier plate (6) with a second reference surface. The second reference surface lies opposite the first reference surface and causes a second degree of spherical aberration, different from the first, to incident light. A flexible element (1) is arranged between the first and second carrier plates (4,6). The flexible element has a reflective surface and is formed such that it can be matched to the first or second reference surface. A driver (9) is provided to adapt the flexible element to the first or second reference surface. The flexible element (1) is held between the first and second carrier plate. Light radiation reflected by the reflective surface undergoes spherical aberration such that the flexible element is adapted to the reference surface by the driver (9).

Abstract: An ink jet head has an ink head main body that is constituted of a substrate (5), spacers (6) that are formed on one side of the substrate, and a roof plate (7) that is joined to the substrate (5) through the spacers (6). One or more ink passages (2) are independently formed between the substrate (5) and the roof plate (7). Rows of piezoelectric devices (3a), each of which is made of a plurality of piezoelectric devices (3a) aligned along an ink passage (2), are associated with the respective ink passages. Ac voltages whose phases are different from each other by 90 degrees are applied to the respective piezoelectric devices. Progressive waves, which are excited by the rows of piezoelectric devices (3a), allow ink to move through the ink passage (2) and to be sprayed.

Abstract: A microrelay including a substrate (100) having a pair of fixed contacts (110) fixed on a surface thereof and a movable section (200) having a pair of movable contacts (222) opposed to the pair of fixed contacts. The movable section (200) includes a frame (210) for fixing the movable section to the substrate; a movable body (220) having the pair of movable contacts (222) and a pair of magnetic bodies (223); and a coupling section (230) for pivotally supporting the movable body (230) to the frame (210). The substrate (100) has a pair of magnetic force generating devices (250) for supplying the pair of magnetic bodies (223) with a magnetic force, thereby selectively causing contact between one of the pair of movable contacts (222) and the fixed contact (110) opposed to the one of the pair of movable contacts (222); and a magnetic force controlling device (120) for applying the magnetic force generated by each of the pair of magnetic force generating devices (250) only to the magnetic body (223) corresponding to each of the magnetic force generating device (250). A method for producing such a microrelay includes the steps of depositing an insulating film on the surface of the substrate (100); forming the pair of fixed contacts (110) each formed of a conductive film on the insulating film; and forming a groove (120) at the surface of the substrate (100) between the pair of fixed contacts.

Abstract: The ink is taken into a cavity (35) supplying nozzles (36) in a perforated plate (33) above a pressure generator (32) based on a bending element (38) under which a heating element (39) is inserted between insulating layers (40,41). The bending element is symmetrical about its centre and has its edges secured to the substrate (31) within the cavity. A tapered fluid inlet (43) leads through the substrate into a gap (42) under the heating element, which is patterned for uniformly distributed heating. The cavity is connected to an ink reservoir (34) by a passage (37).

Abstract: The print head (10) has a chamber (5) with an inner vol. filled with ink (100), an ink ejection aperture (5a) and an ink delivery aperture (5b) connected to the inner chamber. Several inflatable bodies (1) are arranged in the inner chamber between the apertures to place the ink under pressure. An inflation device is connected to the inflatable bodies. The chamber has a first and second opposing inner surface section with the inner vol. between them. A first inflatable body is attached to the first inner surface section via an attachment (3). The second inflatable body is connected (3) to the second inner surface section so as to face the first inflatable body. When voltage is applied (9) the inflatable bodies expand but are restricted by the attachments, hence exerting pressure on the ink.

Abstract: The printhead has ink delivered through a hole (102) at right angles to a monocrystalline Si substrate (101) surrounding a piston (103) with a gap (105) of less than 5 microns. Both ends (107) of the body (106) carrying the piston are fixed to the substrate with interposition of a heating layer (109) between upper and lower insulations (110,111).The ink cavity (117) feeding the nozzle (116) is bounded by an adhesive layer (14) at each end of the body. The heating layer is warmed rapidly by pulses of current, causing the piston to be lifted by thermal expansion of the body.

Abstract: The printhead ejects ink from nozzle openings (3a) tapering from 50 to 30 microns in dia. in a glass nozzle plate (3) opposite the central region (8a) of an ink emission plate (8). The plate ends (8b) are embedded between the nozzle plate and a monocrystalline Si substrate (5).Ink is delivered through an inlet (2b) into a cavity (2a) under the substrate at a pressure which causes the centre of the ink emission plate to rise until it comes into contact with the nozzle openings.

Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive, small-sized optical communication module which is capable of full-duplex communication through one optical fiber and has a high S/N. SOLUTION: The light emitted by a light emitting element 4 is converted by a transmitting lens 6, passes through an optical member 10, and coupled with an optical fiber 2. The majority of receive light 22 radiated from the optical fiber 2 is reflected by a receive light reflecting mirror 7 formed on an optical member 10 and converted, and then coupled with a light receiving element 5. The majority it of received light 22 (reception part reflected light 19) irradiates a radio interference prevention part 8 and is reflected (or absorbed) in a direction wherein it is not coupled with the optical fiber 2. Transmission light 21 reflected by an end surface of the optical fiber 2 is reflected by a shading part 9 as a portion of the radio interference prevention part 8 and not coupled with the light receiving element 5.
