摘要： The present invention relates to a soft robot using diamagnetic levitation. Such a soft robot using diamagnetic levitation is formed of a diamagnetic material to levitate on the ground on which a magnetic field is formed, and moves in a direction toward a predetermined point of a head part when the predetermined point of the head part is heated, and may thus move and change its direction in a state in which it is not in contact with the ground.

摘要： A stored energy release comprises an actuatable member slidably received within a housing. The actuatable member has an extended orientation wherein a portion of the actuatable member extends outwardly from the housing and a retracted orientation wherein the actuatable member resides within the housing. A biasing member is located between the actuatable member and the housing biases the actuatable member to the retracted orientation. A shaft is within the housing with the actuatable member configured for sliding movement along the shaft. A retaining member is located between the actuatable member and the shaft. The retaining member maintains the actuatable member in the extended orientation whereby potential energy is stored within the biasing member. A piezoelectric element selectively engages the retaining member to disable the retaining member and release the stored potential energy within the biasing member to place the actuatable member in the retracted orientation.

摘要： The present invention relates to a piezoelectric motor that can be moved with very fine resolution at the nanometer level by means of a piezoelectric element (piezo actuator) that increases in length when a voltage is applied. The piezoelectric motor according to the invention is characterized by comprising a body having an upper surface and a lower surface, and a side connecting the upper surface and the lower surface, a piezoelectric material disposed on the upper surface of the body and extending longitudinally therefrom, and a rod having an upper surface and a lower surface, and extending longitudinally, and having one end connected to one end of the piezoelectric body and disposed on the upper surface of the body, and a support member disposed to span the rod and providing a predetermined frictional force on the rod, wherein the support member is driven by the rod to interlock with a contraction or an expansion of the piezoelectric material, wherein a lower surface of the support member and the upper surface of the body are at least partially in butted, and wherein the support member is driven by sliding on the upper surface of the body.

摘要： An image pickup apparatus is capable of decreasing a space capacity occupied by component elements and being downsized compared to a case where an actuator is arranged independently of a supporting unit. The image pickup apparatus has an image pickup unit driven by the actuator, a base unit, and the supporting unit provided in a standing manner from the base unit and rotatably supports the image pickup unit. The actuator has a piezoelectric element and an oscillator including a transmission unit which transmits driving force caused by vibration excited by the piezoelectric element. The transmission unit is arranged in the supporting unit so that it is in pressure contact with the image pickup unit. The image pickup unit has a transmitted plane with which the transmission unit is brought into pressure contact, and the vibration excited by the oscillator causes the transmitted plane to move relatively to the oscillator.

摘要： A vibration-type actuator includes a vibration body including an electric-mechanical energy conversion element with a lead content of 1000 ppm or less, and an elastic body having a plate portion and protrusions protruding in a direction intersecting with a main surface of the plate portion, and a contact body in contact with the protrusions. The vibration body and the contact body are relatively moved by vibration of the vibration body. The vibration-type actuator further comprises a pressure member pressing the vibration body against the contact body and a foamed member arranged between the pressure member and the vibration body. The foamed member contains, as a main skeleton, a siloxane bond including silicon and oxygen, and an average equivalent circle diameter of bubbles contained in the foamed member is greater than 120 μm.

摘要： A vibration power generation device includes a beam including a flat surface, a piezoelectric member disposed on the flat surface of the beam, and a fixation member. The fixation member sandwiches the beam at two or more end portions of the beam from a side of a first surface of the beam and from a side of a second surface of the beam, the second surface being opposite to the first surface. At at least one of the end portions of the beam, a position of a boundary on the first surface between a contact region of the first surface in contact with the fixation member and a non-contact region of the first surface is different from a position of a boundary on the second surface between a contact region of the second surface in contact with the fixation member and a non-contact region of the second surface.

摘要： A vibration power generation device includes a weight, multiple beams, and a fixation member. The beams extend from the weight in multiple directions parallel to a single virtual plane. The beams are provided with piezoelectric members. The fixation member fixes in place, in multiple fixing regions FR, the multiple beams while maintaining tension on the multiple beams. The multiple fixing regions FR extend along a peripheral direction around an axis in a direction perpendicular to the virtual plane. The weight and the piezoelectric members are surrounded by the multiple fixing regions FR.
