A cantilever type probe comprises a cantilever-shaped displacement element having electrodes for driving which displace two layers of piezoelectric material at the interface and first and second surfaces of the layers, respectively, and each of the electrodes being arranged separately within the same plane, and a tip for information input and output connected to electrodes for drawing out arranged separately from the electrodes for driving at the free end of either one of the first and second surfaces of the element. A scanning tunneling microscopy or an information processing device comprises the cantilever type probe, a driver for driving the displacement element of the cantilever type probe and a bias or pulse voltage applicator for applying a bias or pulse voltage between a sample and the probe.
摘要:
A cantilever unit comprises a cantilever for supporting a probe and a displacement amount detecting means, the displacement amount detecting means being integrated with the cantilever. An information processing apparatus comprises the cantilever unit and optionally an information recording medium stationed in close vicinity to the unit, wherein an information in the medium is reproduced at a signal on the basis of an displacement amount of the cantilever. An atomic force microscope and magnetic force microscope comprise the cantilever unit, respectively.
摘要:
An angular acceleration sensor has a weight member, a resilient member for supporting the weight member from the both sides thereof, the resilient member being disposed on a predetermined rotational axis and supporting the weight member for rotation about the rotational axis, and an opposed member opposed to the weight member, an angular acceleration applied to the weight member being detected from a variation in the spacing between the opposed member and the weight member resulting from the rotation of the weight member
摘要:
A parallel plane holding mechanism is constructed as follows. Beams are provided on the peripheral portion of a flat plate-shaped weight member. A base plate is provided so as to face the weight member. First and second electrodes are provided on both surfaces of the weight member and the base plate to face each other. A voltage is applied between the first electrode and the second electrode so that the distance between the weight member and the base plate is controlled to move the weight member to thereby hold a reference surface of the weight member to be parallel to a predetermined reference surface.

A micro-displacement element comprises a unimorph cantilever having a piezoelectric thin film, a pair of electrodes between which the piezoelectric thin film is sandwiched, and an elastic thin film. One end of the cantilever is supported by a support, and the other end thereof is provided with a probe. The micro-displacement element can be used particularly as an array of plural elements, for an information processing apparatus in which the element faces to a recording medium such that an information recording pulse voltage or an information reproducing bias voltage can be applied to between the probe and the recording medium.
摘要:
A process for producing a probe-driving mechanism. A laminate of a first and second insulating layer is placed on a support. Electrode layers and piezoelectric layers are successively laminated on the second insulating layer. Part of the support and second insulating layer is removed to form a cantilever.
