摘要： PROBLEM TO BE SOLVED: To enable formation of an ink jet printing head which uses piezoelectric material membrane for discharge pressure generation element in a status where high density is accumulated, by forming a pressure generation chamber with a small volume in a simple process and by simplifying a film thinning process of a vibration plate. SOLUTION: The ink jet printing head is manufactured so that a vibration plate and piezoelectric element for discharging ink is formed in an ink channel structure. The structure is equipped with two or more pressure generation chambers which are connected to ink pool with continuous holes. The pressure generation chambers are formed on an Si substrate. On the opposite side of the pressure generation chambers of the vibration plate, a free space is prepared with side walls formed with Si surfaces. COPYRIGHT: (C)2004,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To lessen deterioration of formed images even when a temperature in an image-recording apparatus and an environment temperature change by setting a coefficient of thermal expansion of an encoder scale to be nearly equal to a coefficient of thermal expansion of a carriage. SOLUTION: An image-recording means consists of recording heads 2a-2d, a carriage 3, an encoder scale 4, nozzles 5a-5d and encoder detect parts 6a-6d. The carriage 3 is formed of a polyphenylene oxide resin or the like, and the encoder scale 4 is formed of a polycarbonate resin or the like. A difference of coefficients of thermal expansion is thus made not larger than 5×10-5/ deg.C. Accordingly a difference in deviation of hit positions in a transfer direction of ink drops to be discharged to an equal position from the recording heads 2a-2d can be reduced between a start and an end of recording, so that good images can be obtained.

摘要： PROBLEM TO BE SOLVED: To provide a liquid ejection element, and a manufacturing method thereof, in which a plurality of liquid chambers, inner electrodes and a piezoelectric part are constituted integrally without exposing the inner electrode to the inner wall face of the liquid chamber and liquid can be ejected efficiently and highly accurately. SOLUTION: Electrodes 3, 4 are formed on ceramics green sheets 2a, 2b, respectively, by printing and laminated with another ceramics green sheet 2c. A burn-out structure 10 of a carbon compound or wax for constituting a liquid chamber is arranged thereon and supplied with piezoelectric sludge to produce a ceramics green sheet 2d of specified thickness on which an upper electrode 5 is formed by printing. A plurality of such laminate sheets are laminated and integrated and then cut into specified size. Subsequently, it is fired and the burn-out structure 10 is burnt out to form a liquid chamber thus obtaining a multiplayered piezoelectric liquid ejection element comprising inner electrodes 3, 4, 5 comprising a plurality of triple layers, a plurality of liquid chambers and a piezoelectric part are integrated.

摘要： PROBLEM TO BE SOLVED: To suppress a decrease in an ink absorbing amount of an ink receiving layer under a high humidity condition by omitting use of a mold release sheet by releasably providing a transfer protective member on a rear surface of a base material as for forming a transparent protective film of a recorded image. SOLUTION: A recording medium F2 is superposed on a recording medium F1 obtained by recording a full color image on an ink receiving layer 5 from a transfer protective member 3 side provided on a rear surface of an ink receiving layer 2. Then, it is passed between roller pair 6, thermally press bonded, and a transparent protective film 3' is formed on a front surface of the layer 5. A portion 7 made of a base material 1 of the medium F2 and the layer 2 is released, and a record is obtained. Then, an image is formed on the portion 7 by a recording head 8, the medium F2 is superposed, laminated on the medium F1, and a new record f2" and a new recording medium F2' covered on an image surface with the protective film are obtained. An ink receiving layer of the medium F2' is heated by the pair 6, dried and hence high ink absorbency can be realized even under a high humidity condition.

摘要： PROBLEM TO BE SOLVED: To provide an opening/closing device for fluid which is small in size, light in weight, simple in structure, and highly reliable in operation. SOLUTION: In a support member 9 made of chlorinated butyl rubber, an opening 2 on the inlet side and an opening 3 on the outlet side, each serving as a joint to which a supply pipe is connected, and a through-passage consisting of an opening for the communication of the opening 2 on the inlet side and the opening 3 on the outlet side are formed. A valve element 20 comprising two platelike shape-memory alloys is supported in the through-passage so as to be deformable for switching back and forth between the blocked state and communicating state of the through-passage. The two shape-memory alloys are joined together in the caulking area 16 of their ends. The shape-memory alloys 5 are deformed by causing a current to flow in the valve element 20 through electrode leads 7, so that the through-passage in the support member 9 communicates by an empty space between the two shape-memory alloys 5. By stopping the supply of the current to the valve element 20, the shape-memory alloys 5 return to their original states by the elastic force of the support member 9, and the through-passage is consequently blocked.
