摘要： PROBLEM TO BE SOLVED: To provide a solar battery which has superior photoelectric conversion efficiency. SOLUTION: The solar battery 1 is the so-called 'dry solar battery' and is composed of a substrate 2, a 1st electrode 3 which is installed on the top surface of the substrate 2, a filmy semiconductor 4 installed on the top surface of the 1st electrode 3, and a 2nd electrode 5 which is installed on the top surface of the semiconductor 4 and has a Schottky barrier formed on the interface between the 2nd electrode and the semiconductor 4. The solar battery 1 has R52/R90 of, preferably, >=0.8, where R52 is photoelectric transduction efficiency, when the angle of light incidence is 90 deg. and R90 is the photoelectric transduction efficiency when 90 deg.. This semiconductor 4 is principally made of titanate and is preferably porous. This semiconductor 4 is preferably filmy and 0.1 to 300 μm in thickness. Furthermore, the semiconductor 4 is preferably processed by band-gap reduction, so that its band gap becomes small.

摘要： PURPOSE:To enhance an energy efficiency and productivity and stabilize ink discharge characteristics by filling spaces among a nozzle forming member and vibrators with ink and mounting a flying member and a return spring, which are laminated to each other, at the movable end of each vibrator. CONSTITUTION:Flying members 12 are usually pressed to the upper ends of vibrators 13 by a spring force of return springs 11. Ink 21 is supplied from the exterior of a frame 20, ascends through gaps among the respective vibrators 13 due to a capillary force and is filled up to nozzle openings 16. When a drive voltage is so applied as to extend the vibrators 13 at the time of the discharge of ink, the movable ends 28 of the vibrators 13 are displaced toward the nozzle openings 16, so that the flying members 12 and the return springs 11 are pushed upward, and ink droplets 25 are thereby discharged.

摘要： PURPOSE:To prevent the occurrence of defective products due to a short circuit between each segment electrode by a method wherein the segment electrodes on a base plate for giving instructions to piezoelectric transducers are so arranged as not to reach the end face of a base plate. CONSTITUTION:Since segment electrodes 12 do not reach the edge of a stamped part 13 of a base plate 8, there is neither occurrence of the burr resulting from the press working of a conductor nor entry of a conductive adhesive agent between the segment electrodes and a base member. Therefore, no short circuit occurs between the base member 10 and the segment member 12. The structural pattern of the conductors on the base plate spaced apart from one another can be achieved by electroless deposition in a plating process.

摘要： PURPOSE:To stabilize gaps between the movable parts of a piezoelectric transducer and nozzle forming members and improve the repeatability and accuracy of ink droplet delivering characteristics by using a flexible base plate as the substrate of the piezoelectric transducer. CONSTITUTION:By using a flexible base plate 8 as substrate, there is no occurrence of deformation resulting from the difference in thermal expansion coefficient taking place when a conductive adhesive agent 7 is hardened. Specifically, since the Young's modulus of the flexible base plate is very small on the whole, there is no deformation taking place due to the difference in thermal expansion coefficient between nozzle forming members 5 and a piezoelectric transducer 4 even after the formation of a joint therebetween. The piezoelectric transducer 4 is supported by the nozzle forming members 5. Moreover, since the flexible based plate is also used to serve as a cable for receiving a signal from the exterior, the process of joining together this flexible base plate and a base plate at a fine pitch is omitted to prevent the reduction of yield rate due to the formation of such joint.
