Abstract: A pad main body is bonded integrally with an inner pad while covering the front side of the inner pad. A back-side reinforced fabric located on the back side of the pad main body and the inner pad is integrally bonded on the back side of the inner pad and the pad main body by impregnation of foamed synthetic resin materials constituting the inner pad and the pad main body. This allows impregnation of the foamed synthetic resin materials in the back-side reinforced fabric located on the back side of the inner pad and the pad main body. This consequently allows providing a high hardness on the back side of the inner pad while ensuring hardness on the back side of the pad main body.

Abstract: A method of manufacturing an interconnection member includes forming on a substrate a wettability changing layer containing a material in which critical surface tension is changed by giving energy; forming a depression part in the wettability changing layer by a laser ablation method using a laser of an ultraviolet region; and coating the depression part with an electrically conductive ink to form an electrically conductive part. At the same time when a pattern of the depression part is formed in the wettability changing layer, a pattern of a high surface energy area is formed as a result of the critical surface tension being changed.

Abstract: A fuel-cell system with a fuel battery comprising more than one fuel cell having a purge gas passage connecting the fuel battery to a purge gas cylinder, a discharge passage connecting the fuel battery to the exterior, solenoid valves each installed in the passages, and an electronic control unit that opens the solenoid valves to open the passages to supply the purge gas to the fuel battery such that residue in the fuel battery is purged to the exterior by the purge gas. The control unit opens the valves at a time interval determined from an output of a current sensor to conduct purge at optimum timing for the battery operating state so as to prevent accumulation of residue in the fuel battery, while preventing repetition of unnecessary purges.

Abstract: A drop-on-demand ink-jet printing head provided with an array of a plurality of piezoelectric elements arranged at regular intervals and fixed at their one ends to a base, the other ends of the respective piezoelectric elements being free ends which are disposed in opposition to nozzle respective apertures, the piezoelectric elements being formed by cutting, at predetermined width, a piezoelectric plate obtained by firing a lamination of paste-like piezoelectric material conductive material stacked alternately in layers. Since each piezoelectric element is composed of a thin piezoelectric plate interposed between electrodes, if a voltage of only about 30 V, which is sufficient to drive the thin piezoelectric plate, is applied across the electrodes, it is possible to largely flex the whole of the piezoelectric element. By this transformation, ink between the top end of the piezoelectric element and the nozzle aperture is discharged to the outside as an ink drop.

Abstract: This invention is a technique for automatically generating a suitable digest of the content, which can attract the interest of many viewers. This invention comprises the steps of: acquiring user instruction information associated with a specific content, such as information concerning a re-viewing desired range designated by the user and information concerning a delivery request for the specific content, from a user terminal that is a delivery designation; and generating a digest of the specific content based on at least the user instruction information. Moreover, this invention may further comprise a step of acquiring information concerning a scene change of the specific content, and in the digest generating step, the digest may be generated based on the information concerning the scene change and the information concerning the delivery request of the specific content. This is because the digest is made not to start from a halfway place in the middle of the scene.

Abstract: A piezoelectric actuator, comprising a stacked structure consisting of a top electrode 5, a piezoelectric film 4, and a bottom electrode 3, wherein the piezoelectric film comprises a first group 42 of piezoelectric ceramic particles and a second group 43 of piezoelectric ceramic particles. A distinctive feature is that the particles constituting the first group of piezoelectric ceramic particles are larger than the jingo particles constituting the second group of piezoelectric ceramic particles, and the first group of piezoelectric ceramic particles and the second group of piezoelectric ceramic particles have mutually different compositions. The piezoelectric actuator can thus be manufactured by an application method in a low-temperature environment, and a thicker piezoelectric film can be obtained. In addition, a highly practical piezoelectric film can be provided by combining the advantages of a plurality of material types.
