IPC: H01L31/04
Filed: 1989-12-14
Abstract: PURPOSE:To improve a solar cell of this design in durability by a method wherein an ethylene-tetrafluoroethylene copolymer biaxially oriented film is used as a solar cell module protective film. CONSTITUTION:A solar cell module is composed of a substrate 1 of glass, stainless steel, or the like and an amorphous silicon 2, or a solar cell element of CdS/CdTe or the like and a protective film 5 of ethylene-tetrafluoroethylene copolymer biaxially oriented film. In this case, as the protective film 5 is formed of ethylene-tetrafluoroethylene copolymer biaxially oriented film, it is needless to say that it hardly deteriorates over a long term when it is kept at normal temperature and humidity, and further it also hardly deteriorates even if it is kept at high temperature and high humidity, and as it is kept transparent, a solar cell of this design can be prevented from deteriorating in photoelectric conversion efficiency. As the surface of the protective film 5 is lubricant, foreign particles, dusts, and the like are hardly attached to it, in result it is prevented from deteriorating in light transmittance. By this setup, a solar cell of long life can be obtained.

Title: Ultrasonic motor
Inventor: ICHINOSE KICHIJU
IPC: H02N2/00
Filed: 1988-12-23
Abstract: PURPOSE:To improve starting performance by applying pressure component of a spring member between a stator and a mover through a rolling lever arranged between two mover sections. CONSTITUTION:Since pressure contact force between movers 4a, 4b and a stator 1 is small, traveling wave produced in the stator 1 is received by the mover section 4a at the side of the stator 1, when a motor is started, and the motor is rotated or moved slightly with small driving force. Since a large load functions through an output shaft 5 onto the mover section 4b remote from the stator 1, the mover section 4b does not move and the force of a spring member 10 for pushing a rolling lever 11 increases through motion of the mover section 4a at the stator 1 side thus increasing the force of the rolling lever 11 for pushing the mover section 4a toward the stator 1 side. Consequently, the mover section 4a at the stator 1 side is pushed strongly against the stator 1 and the traveling wave is received more effectively thus moving the motor with gradually increasing driving force.
