  • Publication number: 20040238026
    Abstract: There is provided a dye sensitizing solar battery unit having a high durability in its bonding portion. A fitting protruding wall portion 11C is formed so as to extend along the peripheral portion of a photoelectrode substrate 11 of a resin, and afitted protruding wall portion 12A is formed so as to extend along the periphery of a counter electrode substrate 12 of a resin. By fitting the fitting protruding wall portion 11C into a space defined by the fitted protruding wall portion 12A, the fitting protruding wall portion 11C is caused to tightly contact the fitted protruding wall portion 12A to enhance the bonding strength therebetween. In addition, a plurality of spacer portions 11B are integrally formed on the photoelectrode substrate 11 at regular intervals for holding a predetermined distance between the photoelectrode substrate 11 and the counter electrode substrate 12. Thus, the plurality of spacer portions 11B are uniformly arranged to enhance the durability of the dye sensitizing solar battery unit.

  • Patent number: 6372977
    Abstract: In the case of using a solar battery formed by growing an amorphous silicon film on a substrate as a watch face for an electronic watch, there had been great restrictions with regard to the design of the watch face. If it is possible to impart transparency to light to the substrate onto which is formed a solar battery, so that it is possible to achieve a form of solar battery that is not perceivable, it is possible, by using a substrate onto which is formed this solar battery either on the watch face or on a protective glass crystal or the like, to achieve a watch with a solar battery not restricted with respect to watch face design.

  • Publication number: 20020036673
    Abstract: An ink jet head, for use in an ink jet recording apparatus, comprising an ink chamber, a member constituting the ink chamber being made of a plastic material having a surface possessing a hydrophilic nature imparted by surface treatment, for introducing a polar group, selected from the group consisting of acid treatment, ultraviolet light-ozone irradiation, and oxygen plasma treatment, and a process for producing the same. When the ink jet head is used in an ink jet printer using a water-base ink, the wettability of an ink flow passage within the head is good and, in addition, the good wettability can be stably maintained, permitting a high print quality to be ensured for a long period of time.

  • Patent number: 5879960
    Abstract: A thin film diode (8) between a data line (12) and a drive electrode (13), which is free from breakage in an upper layer film (4), is formed on one inner surface of a glass substrate (1) sealing a liquid crystal of a liquid crystal display device. To form such a thin film diode, a lower layer film (2) is formed on the glass substrate (1) such that the lower layer film (2) overlaps with the upper layer film (4) and the lower layer film (2) has a plurality of differences in level. An insulating film (3) is formed by oxidizing the surface of the lower layer film (2) with an anodic oxidation technique. The upper layer film (4) is formed, thereby completing the thin film diode. Alternately, an insulating film material (7, 7') may be formed either on the lower layer film (2) or on the peripheral region thereof in the form of a film, and the insulating film (3) may be formed by oxidizing the insulating film material (7, 7').
