A back cleaner operating on a direct current battery which supplies current to turn an electric motor with an extension rod approximately eight inches in length which operates as the drive shaft. In the brake system, a first check valve is mounted at an upstream position of an oil suction line which guides pressurized oil from the master cylinder to the inlet of the oil pump during a TCS mode, while a second check valve is mounted on an oil feeding line, which guides pressurized oil from the intermediate-pressure accumulator to the inlet of the oil pump through the oil suction line. The green recording layer comprises a second image dye-forming coupler and radiation-sensitive silver halide grains for forming a developable latent image upon imagewise exposure.
