20090001998 | Capacitance Detecting Apparatus - A capacitance detecting apparatus which can detect the change in minute capacitance of a measuring object with high sensitivity comprises a signal generator, a differential amplifying circuit, and a detecting unit. The signal generator generates a probe signal w(t) to be applied to one end of the measuring object. The differential amplifying circuit amplifies differentially a response signal v | 01-01-2009 |
20090097385 | INFORMATION RECORDING/REPRODUCING APPARATUS - A probe group is composed of, for instance, four probes adjacently arranged, and one modulation circuit is arranged for each probe group. At the time of recoding information, a changeover switch connects one of the four probes with the modulation circuit, and subsequently changes the probes to be connected with the modulation circuit while reciprocal movement of a recording medium is being controlled. | 04-16-2009 |
20090178167 | INFORMATION MEMORY APPARATUS USING PROBE - A first thermal buffer layer and a second thermal buffer layer are arranged between a recording medium and an actuator structure. The heat conductivity of the first thermal buffer layer is set low and the heat conductivity of the second thermal buffer layer is set high. Most of the heat generated from a coil wiring of the actuator structure is blocked by the first thermal buffer layer, and heat leaked from the first thermal buffer layer is diffused by the second thermal buffer layer. Temperature distribution on the recording medium is made uniform, and thus, a configuration wherein the recording medium and the actuator structure are placed one over another can be provided, information reading accuracy or information recording stability can be improved and the sizes of an information storage device can be reduced. | 07-09-2009 |
20090178168 | INFORMATION MEMORY APPARATUS USING PROBE - In a two-dimensional probe array, an interval between the leading ends of probes adjacent to each other in an X direction is made shorter than that between the leading ends of probes adjacent to each other in a Y direction. Thus, the leading ends of the probes are arranged to form a lattice wherein many rectangles are arranged. Furthermore, the lowest resonance frequency of an actuator which moves a recording medium in the X direction is set higher than the lowest resonance frequency of an actuator which moves the recording medium in the Y direction. At the time of recording or reading information, the recording medium is reciprocated in the X direction at a frequency substantially equal to the lowest resonance frequency of the actuator. | 07-09-2009 |
20090217425 | Driving apparatus - A driving apparatus is provided with: a stage structure on which a medium having a small recording domain is mounted; and a facing structure which is provided with at least one small action structure, which faces the medium, for performing a predetermined action to the medium, and which is displaced relatively on a predetermined flat surface with respect to the stage structure, the facing structure comprising a facing-side position detecting unit for detecting a relative reference position of the facing structure with respect to the stage structure, the stage structure comprising a stage-side position detecting unit for detecting a relative reference position of the facing structure with respect to the stage structure. | 08-27-2009 |
