Abstract: Auxiliary washing device in a washing machine comprises a beam mounted on an upper side of an outer tub and extended to an inner space of a washing tub, and a washing bar supported at an extended end of the beam to be capable of swinging. The washing bar is swung upwardly by a motor and downwardly by a torsion spring. When electric power to the motor is stopped at the position in which the washing bar is swung upwardly by the motor, the washing bar swings downwardly by the torsion of the torsion bar to strike laundry in the washing tub. Thus, washing is enhanced by the impact to the laundry, and the laundry is stirred upwardly and downwardly. Therefore, inefficiency in the upper part of the washing tub due to the washing operation only by pulsator is prevented, and washing of all clothes is enhanced.

Abstract: A digital disk player recognizes a signal recording layer in a loaded disk, which includes a pickup for converting an optical signal read from the loaded digital disk into an electrical signal, a converter for converting the electrical signal output from the pickup into an electrical pulse signal of which the number of pulses varies according to the number of the signal recording layers in the loaded disk, and a controller for controlling an initial focusing operation of the pickup based on a position corresponding to focus position and determining whether the signal recording layer of the loaded disk is a multilayer or a single layer recording layer based on the number of the pulses contained in the electrical pulse signal input to the converter. The controller controls a display such as a digitron to display the number of the layers which corresponds to the number of the pulses.
