Abstract

[Object] To provide a piezoelectric pump that has a simple structure and that can increase the discharging pressure. [Solving Means] A first opening 11 is provided in a center portion of a pump body 10, and a second opening 12 is provided apart from the center. An outer peripheral portion of a metal diaphragm 20 is fixed to the pump body 10, and a piezoelectric element 23 having a size such as to cover the first opening 11 and such as not to reach the second opening 12 is bonded to a back center portion of the diaphragm 20. By applying a voltage near the resonance frequency to the piezoelectric element 23, a portion of the diaphragm 20 opposing the first opening 11 and a portion of the diaphragm 20 opposing the second opening 12 are bent in opposite directions so that fluid is drawn in from one of the first opening 11 and the second opening 12 and is discharged from the other opening. This can increase the discharging pressure, and can reliably discharge the fluid even under a condition where the pressure on the discharging side is high.

Abstract

A system and a method are realized in which in a conventional non-grounding man-machine interface having no reaction base on the human body and for giving the existence of a virtual object and the impact force of a collision to a person, a haptic sensation of a torque, a force and the like can be continuously presented in the same direction, which can not be presented by only the physical characteristic of a haptic sensation presentation device. In a haptic presentation device 112, the rotation velocity of at least one rotator in the haptic presentation device 112 is controlled by a control device 111, and a vibration, a force or a torque as the physical characteristic is controlled, so that the user 110 is made to conceive various haptic information of the vibration, force, torque or the like. The haptic information presentation system uses a human sensory characteristic or illusion to suitably control the physical quantity, and causes the person to feel a force which can not exist physically, or a haptic sensory physical characteristic.

Abstract

Power non-supplied side radiation electrode 3 and power supplied side radiation electrode 4 are formed on the surface of a dielectric substrate 2 with a space therebetween. A permittivity adjusting material portion 8 is provided in the space S which is situated between the power non-supplied side radiation electrode 3 and the power supplied side radiation electrode 4, and in which a capacity occurs. The permittivity adjusting material portion 8 has a lower permittivity than that of the dielectric substrate 2, which causes the permittivity between the power non-supplied side radiation electrode 3 and the power supplied side radiation electrode 4 to be lower than that of dielectric substrate 2, and weaken the capacitive coupling between the power non-supplied side radiation electrode 3 and the power supplied side radiation electrode 4. As a result, it becomes possible to suppress the mutual interference of the resonances of the power non-supplied side radiation electrode 3 and the power supplied side radiation electrode 4, and to thereby improve antenna characteristics, without taking measures such as widening of the space S between the power non-supplied side radiation electrode 3 and the power supplied side radiation electrode 4, or a reduction of the permittivity of the dielectric substrate 2, the measures - 42 - hindering the surface-mounted type antenna 1 from miniaturization.
