摘要:
A clothes amount sensing method in a washing machine which is capable of reducing clothes amount sensing errors caused by frictional forces, thereby achieving an enhancement in accuracy and reliability. The method includes an acceleration step for accelerating, to a predetermined RPM, a motor adapted to rotate the wash tub, a constant-speed step for maintaining the motor at the predetermined RPM when an RPM of the motor reaches the predetermined RPM in accordance with the acceleration step, a deceleration step for turning off the motor to decelerate the motor, following the constant-speed step, and a clothes amount determination step for determining the amount of the clothes by use of equations of motion respectively established in the acceleration, constant-speed, and deceleration steps.

Disclosed herein is a suspension apparatus and a resonance avoiding method of a drum-type washing machine. The method adjusts elastic moduli of elastic members before a drum reaches a resonance speed during a dehydration cycle of the washing machine. If the rotating speed of the drum exceeds the resonance speed, the method returns the elastic moduli of the elastic members to an initial state, thereby preventing generation of resonance.

A damper for damping vibration and a washing machine having the same are disclosed. The damper includes a damper cylinder; a shaft inserted into the damper cylinder through one end of the damper cylinder, and reciprocating in the lengthwise direction of the damper cylinder; and a friction member provided on the shaft for damping vibration generated by friction with the inner wall of the damper cylinder, and moving vertically to the lengthwise direction of the damper cylinder. The damper adjusts damping force thereof according to vibrated states of an object to be vibrated, and has an improved vibration-damping effect.

Disclosed herein is a damper for use in a drum type washing machine, which can support a tub of the washing machine and absorb vibration of the tub. The damper comprises a cylinder, a piston partially inserted inside the cylinder, and a fixed damping member and movement prevention means, which are installed around an inserted portion of the piston inside the cylinder so that they are spaced apart from each other, and adapted to allow the piston to be stably supported inside the cylinder even in case that a tub of the washing machine vibrates in a non-axial direction of the cylinder and piston, thereby restricting a relative angular rotation of the cylinder and piston and preventing rubbing and collision caused between a lower end of the cylinder and the piston.

The present invention provides a washer, damper thereof, and control method thereof, by which noise is reduced by adjusting a damping force of the damper in a manner of turning on/off power of the damper according to an oscillation frequency of a vibrating body such as a washer. The control method reduces noise by supplying power to a damper in an excessive vibration state of a vibrating body such as a washer or by cutting off the power supplied to the damper in a normal vibration state of the vibrating body.

A mechanism for mounting a motor driving a drum to a tub of a washing machine, and a washing machine using the same are disclosed. The mechanism includes a motor located on the outer surface of a tub; at least one fixing member passing through a part of the motor and then fixed to the tub for fixing the motor to the tub; and at least one isolator provided between the motor and the fixing member for preventing the fixing member from directly contacting the motor to prevent the vibration of the motor from being transmitted to the tub through the fixing member.

A method of fabricating a flash memory device includes depositing and etching an insulating layer on a substrate having STI structures, depositing a first polysilicon layer over the insulating layer and the substrate, etching the first polysilicon layer to form floating gates and removing the insulating layer. The method also includes forming a first photoresist pattern, performing a first ion implantation using the first photoresist pattern to form first source/drain regions in the substrate and adjacent to the floating gate, removing the first photoresist pattern, depositing an ONO layer on the resulting structure, depositing a second polysilicon layer over the ONO layer, and etching the second polysilicon layer to form a control gate and at least one select gate. The method concludes by forming a second photoresist pattern and performing a second ion implantation using the second photoresist pattern to form second source/drain regions in the substrate and adjacent to the select gate.
