Title: Weight sensor, washing machine using weight sensor
Inventor: KONDO FUMITAKE
IPC: D06F37/24
Filed: 2001-11-21
Abstract: PROBLEM TO BE SOLVED: To enable high-precision measurement by a weight sensor, which utilizes an ultra-magnetostrictor for detecting a load quantity or the like in a washing machine. SOLUTION: A second coil 6 for causing an impulse current to flow to remove hysteresis, is formed differently from a first coil 3 for causing an oscillating current of LC oscillation to flow, to detect the change of the inductance of the ultra-super magnetostrictor 2 caused by the change of an external load, and is doubly wound around the ultra-magnetostrictor 2. Consequently, hysteresis can be surely removed, since it is possible for the second coil 6 to have a large wire diameter, which corresponds to the impulse current. Also, since the ultra-magnetostrictor 2 is hardly influenced by heat generation of the second coil 2, even if the second coil 2 generates heat by a flow of an impulse current, its inductance change caused by a temperature change becomes smaller, and the detection precision is increased.

Title: Inkjet recording device
Inventor: HASHI HIROSHI
IPC: B41J2/175
Filed: 2001-11-22
Abstract: PROBLEM TO BE SOLVED: To increase the durability and reliability without damaging an ink- feeding path even when a head is moved between a recording location and a recovering motion location. SOLUTION: Ink feeding paths 17Y, 17M, 17C and 17K connect heads 4Y, 4M, 4C and 4K which are held by a head unit 5 with ink storage means 15Y, 15M, 15C and 15K which are set on the outside. Such ink-feeding paths 17Y, 17M, 17C and 17K are arranged through the vicinity of a turning shaft 7 which turnably supports the head unit 5. Since the ink-feeding paths 17Y, 17M, 17C and 17K are connected with the ink storage means 15Y, 15M, 15C and 15K on the outside through the vicinity of the turning shaft 7, even when the head unit 5 is turned, the ink-feeding paths 17Y, 17M, 17C and 17K are prevented from lifting from the head unit 5. Also, it is not necessary to keep an excessive slack for ensuring the movement of the head unit 5 on the ink-feeding paths 17Y, 17M, 17C and 17K.
