A photocatalyst having superior durability; a manufacturing method for the photocatalyst and a method and apparatus for decomposing a gas, where a film which is fullerene-based but different from the evaporated fullerene film is used. The photocatalyst has a fullerene polymer film layered on a substrate. There may be carried fine metal particles on the fullerene polymer film. These fine metal particles are carried by sputtering, evaporation or coating on the fullerene polymer film. The apparatus for decomposing the gas includes a light source and a fullerene polymer film. In effecting gas decomposition, the gas to be processed is contacted with the fullerene polymer film under light illumination.

A photovoltaic-charged secondary battery device has a cylindrical core, a flexible photoelectric transducer sheet extractably rolled on the core, a chargeable/dischargeable storage battery, and a control circuit for controlling the charging and discharging operations of the storage battery. The photovoltaic-charged secondary battery device with the photoelectric transducer sheet fully rolled on the core generally exhibiting a substantially cylindrical form. The photovoltaic-charged secondary battery device further has a polymeric cover film formed on the light-receiving surface of the photoelectric transducer sheet. The polymeric cover film improves the durability of the photoelectric transducer sheet against repeated bending and sliding actions caused on the photoelectric transducer sheet. The photoelectric transducer sheet may be so arranged that, when the photoelectric transducer sheet is rolled on the core, the light-receiving surface faces outward of the roll. The photovoltaic-charged secondary battery device may have a cylindrical peripheral wall coaxial with the core and defining therebetween an annular space for accommodating the photoelectric transducer sheet rolled on the core. The photoelectric transducer sheet is retractable into and extractable from the annular space through a slit formed in the cylindrical peripheral wall member. The cylindrical peripheral wall member is rotatable relative to the core, so that the photoelectric transducer sheet can be retracted into the annular space and rolled on the core as the cylindrical peripheral wall member is rotated. The cylindrical peripheral wall member may have a plurality of projections formed on the inner surface thereof. The photovoltaic-charged secondary battery device may have a temperature-responsive mechanism operable to disconnect the storage battery from the electrical connection or to move the storage battery from a predetermined position.

Light energy is to be utilized as the power source for a customary electrical equipment. A flexible photo-electric transducer,is arranged so as to be wound about a cylindrically-shaped winding core,. When charging the storage battery,, housed on the winding core,, the photo-electric transducer,wound about the winding core,is pulled out to receive the light.

A ferrimagnetic resonator is disclosed which is stabilized upon temperature deviation and operable over a wide frequency range. The resonator comprises a ferrimagnetic thin film resonance element, a temperature detector for the resonance element a bias magnetic field generating coil, a compensation coil and a compensation circuit. The compensation circuit has a pre-coded compensation data upon operation temperature range and generates a compensation signal in response a detected temperature of the resonance element. The compensation signal is then fed to the compensation coil to generate an additional magnetic field to the resonance element thus the resonance frequency of the resonance element is stabilized upon temperature.
