  • Patent number: 11911933
    Abstract: A molding provided with a sheet-shaped composite material section formed from a fiber-reinforced composite material containing reinforcing fibers and a matrix resin, and protruding ribs formed directly on a first surface of the composite material section and containing a thermoplastic resin, wherein the ribs intersect with each other on the first surface, and the mean width t, mean height H and the proportion occupied on the first surface are within specified ranges. A manufacturing method for the molding including a composite material section-forming step for forming the composite material section, and a rib-forming step for forming the ribs so as to satisfy the above conditions.

  • Publication number: 20220364842
    Abstract: A bridge displacement calculating apparatus comprises a DC component removing part, a high-pass filter part, a first integration part, and a second integration part. The DC component removing part outputs DC-removed acceleration data. The high-pass filter part uses, as a cutoff frequency, the reciprocal of a time in which a vehicle has passed between the frame bodies of the bridge. The first integration part integrates input data thereto. The second integration part integrates input data thereto and outputs displacement data. The high-pass filter part receives DC-removed acceleration data, the first integration part receives the output of the high-pass filter part, the second integration part receives the output of the first integration part, or the first integration part receives the DC-removed acceleration data, the high-pass filter part receives the output of the first integration part, and the second integration part receives the output of the high-pass filter part.

  • Publication number: 20200376674
    Abstract: A sensor module of the present invention includes a flexible body and a sensor fixed to the outer surface of the body. The body is attachable to a robot hand having multiple fingers and is removable from the robot hand. The sensor is a proximity sensor or a tactile sensor. A position on the body where the sensor is fixed corresponds to a fingertip of a finger of the robot hand in a state where the sensor module is attached to the robot hand. The body has the shape of a glove, a finger cot, or a sheet.

  • Patent number: 4887467
    Abstract: A temperature-compensating circuit for a capacitive or prezoelectric resistive accelerometer comprising a flexure with torquer coils subjected to physical changes in response to the linear accelerations, capacitive or piezoelectric resistive elements for detecting strain of the flexure, elements for amplifying the detected output and a negative feedback amplifier for supplying the output to the torquer coils. The output of the piezoelectric resistive element and the resistance of the torquer coils are affected considerably by the temperature change whereby the gain of the feedback amplifier changes. Accordingly, in the circuit of the present invention, the temperature change in the total gain of the accelerometer is removed by adding resistance elements to the negative feedback amplifier so as to cancel the positive temperature coefficient of resistance of the torquer coil and other elements.
