A full automatic washing machine includes in an operation panel a display device together with power ON and OFF switches and a light-emitting diode serving as a pilot lamp. The display device is formed into the shape of a rectangular flat plate and has elasticity. The display device is constituted by a nematic curvilinear aligned phase (NCAP) liquid crystal panel and a reflecting plate. The display device includes a plurality of display sections for displaying a plurality of pieces of information about the washing operation. A membrane switch is disposed on the back of the display device. The membrane switch is turned on when the display device is depressed. The membrane switch has a plurality of key switches positioned so as to correspond to the display sections of the display device.

An automatic washing machine includes a clutch float having external gear teeth. The clutch float is located around a shaft which is driven by an electric motor and to which an agitator is secured. The clutch float couples the shaft to an inner rotatable tub when its external gear teeth are engaged with internal gear teeth at the inner tub side in a dehydration step. The clutch float moves upwardly in subjection to buoyancy when water is supplied into the inner tub in a wash step. The external gear teeth of the clutch float are disengaged from the internal gear teeth so that the shaft is decoupled from the inner tub. The washing machine further includes a rotation restricting float which moves upwardly in subjection to the buoyancy in the wash step to couple the inner tub to an outer stationary tub and which decouples the inner tub from the outer tub in the dehydration step. A device delivers a position signal indicative of the position of the clutch float which is vertically movable. Based on the position signal, a control device controls the drive motor. The drive motor is of an outer rotor type and a motor control circuit is disposed in its stator.

A washing machine includes a dehydrating tub whose interior is divided by rotational angle detecting elements into a plurality of circumferential areas. A period of time required for each area to pass a water pouring location is cumulated by a timer function of a microcomputer in a rinse-with-dehydration operation in which the dehydrating tub is rotated with water being supplied to the tub, A quantity of water poured into or contained in laundry in each area is determined on the basis of a cumulated value so that insufficiency in the quantity of poured water due to rotational unevenness of the dehydrating tub is solved. The washing machine further includes an area display which has area display sections corresponding to the areas and which displays the hydrous state of the laundry in each area, The area display also serves to display the rotational state of the dehydrating tub and an agitator,

A washing machine includes a rotational tub, a single-phase induction motor driving the rotational tub in a dehydrating operation and having a main and an auxiliary coils, a speed detector for detecting a speed of the motor, thereby generating a detection signal, and an output changeover device for changing between an operation mode in which both of the main and auxiliary coils are excited and the other operation mode in which either the main or auxiliary coil is excited. When the motor speed is increased in the dehydrating operation, a control circuit controls the motor in a feedback manner. More specifically, in low and medium speed ranges, the control circuit executes a control pattern in which both of the main and auxiliary coils are excited and selectively executes another control pattern in which only the auxiliary coil is excited when necessary.

The present invention aims to maximally reduce a projecting width of a projecting part formed on a terminal when the terminal is crimped to an exposed core part of an end part of a wire. To achieve this aim, a method for producing a terminal-equipped wire in which a crimping portion of a terminal is crimped to an exposed core part of an end part of a wire includes a) a step of arranging the exposed core part in the crimping portion, b) a step of sandwiching a part of the crimping portion between a lower die surface of a lower die and an upper die surface of an upper die and crimping the part of the crimping portion to the exposed core part, and c) a step of pressing an end part of the crimping portion protruding from the upper die surface from above.

An abnormal vibration detecting device for detecting abnormal vibration of a rotational tub of a washing machine includes first and second abnormal vibration detectors. The first abnormal vibration detector includes a detecting lever rotatively moved where it collides with the rotational tub when it vibrates transversely, and a detection switch responsive to the rotative movement of the detecting lever. The second abnormal vibration detector includes a rotational speed detecting section detecting the rotational speed of a motor driving the rotational tub and a comparator section comparing a speed signal detected by the rotational speed detecting section with a reference speed signal determined based on the rise characteristic of rotation of the rotational tub appearing in the state that the rotational tub is in the condition of slight abnormal vibration.
