摘要： PROBLEM TO BE SOLVED: To provide experimental animal-rearing equipment which can lighten the electric power source of a transmitter, continuously obtain biological signals, maintain a good experimental rearing environment over a long period, and easily supply feeds and water to an animal. SOLUTION: This experimental animal-rearing equipment characterized by comprising a rearing box 13 for receiving an animal 12, an animal-fixing device 14 which has a magnet disposed on the animal and an electromagnet 20 disposed on the rearing box and can attract the magnet to the electromagnet to temporarily restrain the animal, when the electromagnet is energized, and a washing device which has a jet nozzle capable of jetting a fluid to the excretory portion of the animal restrained with the animal-fixing device and a treating device for discharging an excrement 45 separated from the excretory portion of the animal with the fluid jetted from the jet nozzle, whereby the animal in the rearing box is temporarily restrained with the animal-fixing device and the excrement of the animal is removed with the washing device.

摘要： PURPOSE:To realize a piezo-actuator free from a leakage of liquid and excellent in handling properties, safety, and maintainability. CONSTITUTION:A displacement magnifying rubber 4 provided with a recessed part 4a located at its upper center and provided to the upside of a piezo-device 3, a displacement magnifying part 2 provided onto the displacement magnifying rubber 4 enveloping it, and a pushing rod 7 which is inserted into the recessed part 4a of the displacement magnifying rubber 4 penetrating through the upper part of the displacement magnifying part 2 are provided. The displacement of the piezo-device 3 is magnified and transmitted through the pushing rod 7, wherein a rubber is used as an operating medium in place of operating fluid, so that a sealing mechanism which prevents liquid from leaking out of a device can be dispensed with, and a piezo-actuator which is remarkably simplified in structure, lessened in size and weight, and improved in handling properties, maintainability, and safety, and accurate in displacemetn can be realized.
