A bag material has a tubular shape and can be folded back at an intermediate position in a longitudinal direction. Crushed stones can be stored in a folded part of the back material. An opening on one side of the bag material can be moved to a position close to an opening on the other side of the bag material. A one-side closing rope that closes the opening on the one side of the bag material is provided near this opening. An other-side closing rope that closes the opening on the other side of the bag material is provided near this opening. The other of the one-side closing rope and the other-side closing ropes can be released with the opening closed by one closing rope.

Bag material and crushed stone placement method using bag material

A scour prevention unit includes a bag body housing block objects in a bag material, and a cloth integrated with the bag body, wherein the cloth is housed in the bag material and is laid below the block objects, or is fixed below the bag body outside the bag body by fixing means.

Scour prevention unit and scour prevention method

A mist generating device includes a mist generation vibrator, and a sealed vessel accommodating therein a fluid and provided at a side of a vibrating surface of the mist generation vibrator. A wall portion which constitutes a part of the sealed vessel and faces the mist generation vibrator has a thin film membrane and a mist of liquid outside the sealed vessel is generated by ultrasonic vibration transmitted from the mist generation vibrator via the fluid in the sealed vessel and the thin film membrane.

Mist generating device, and dishwasher and washing machine using same

A drum type washing machine includes a housing; a rotary drum having a substantially horizontal or slanted rotational axis; a water tub, suspended in the housing, for accommodating therein the rotary drum; a controller for controlling an operation of the washing machine; and a displacement detecting unit disposed between the water tub and a base portion of the housing, for detecting displacement of the water tub. The displacement detecting unit has a primary coil wound around a bobbin; a first secondary coil without overlapping the primary coil and a second secondary coil overlapping the primary coil, the first and the second secondary coils being wound coaxially with the primary coil; and a magnetic body vertically movable inside the bobbin corresponding to a displacement of the water tub.

Drum type washing machine having vibration detection

A washing machine includes a rotary drum for accommodating therein laundry, the rotary drum having a horizontal or slanted rotational axis; a water tub supported in a vibratable manner in a washing machine main body, the rotary drum being installed in the water tub in a rotatable manner; a motor for driving the rotary drum; an input setting unit for setting an operation of the washing machine; a control unit for controlling the motor and the operation of the washing machine set by the input setting unit, the control unit including a microcomputer; and a displacement detection unit for detecting a displacement of the water tub. The displacement detection unit includes an excitation coil, at least two detection coils having an axis coaxially aligned with the excitation coil and a core which can move along the axis.

Washing machine

A washing machine includes a rotary drum, a water tub, a supporting metallic part, a washing machine base, a motor, a controller, and a vibration detecting unit. The vibration detecting unit, inclusive of a differential transformer having a plurality of coils and a magnetic body, is disposed between the supporting metallic part and the washing machine base and detects a vibration of the water tub.
