  • Patent number: 10706231
    Abstract: Provided is an input apparatus that can reduce incorrect inputs and improve the operability. The input apparatus according to an embodiment of the present technology includes a keyboard module and a control circuit. The keyboard module has a plurality of key areas, and a plurality of sensor devices capable of detecting pressures of keystroke operations for the plurality of key areas, respectively. The control circuit that makes a difference between input sensitivity to the keystroke operation of one key area and input sensitivity to the keystroke operation of a key area next to the one key area on the basis of a pressure information item about each of the key areas next to each other, the pressure information item being detected by the keystroke operation on the plurality of sensor devices at the same time.

  • Patent number: 7454995
    Abstract: A joint mechanism that can be used in an articulated finger unit of a robot hand has first and second actuators that are disposed facing each other from the front and back on either side of a perpendicular joint axle, and first and second drive bevel gears that are coaxially connected and fixed to distal ends of output axles thereof. A driven bevel gear fixedly mounted in coaxial manner on the perpendicular joint axle meshes with the first and second drive bevel gears. The perpendicular joint axle is rotatably driven by the two actuators, and a revolving bracket connected thereto revolves to the left and right. The drive torque of the joint axle can be increased without increasing the outside diameter dimensions of the mechanism.

  • Publication number: 20060152457
    Abstract: A method for driving a liquid crystal display device in which a liquid crystal is driven in a matrix using a plurality of common electrodes and segment electrodes, which are crossed oppositely. While common drive voltage waveforms from each common electrode are sequentially applied to a cholesteric liquid crystal display device, segment electrode drive voltage waveforms from each segment electrode are applied to the device. There is no period of time during which the same voltage is applied to all common electrodes at the same time in a period of time from the application of the hold voltage waveform to the first common electrode to the application of the reset voltage waveform to the last common electrodes, and there is a period of time during which the same voltage is applied to all segment electrodes at the same time.

  • Publication number: 20060011010
    Abstract: A joint mechanism that can be used in an articulated finger unit of a robot hand has two actuators that are disposed in parallel with a vertical direction on a rear side of a perpendicular joint axle, and first and second drive bevel gears are coaxially connected and fixed to distal ends of output axles thereof. First and second driven bevel gears are fixedly mounted in coaxial manner on the perpendicular joint axle, and they mesh with the first and second drive bevel gears. The perpendicular joint axle is rotatably driven by the two actuators, and a revolving bracket connected thereto revolves to the left and right. The drive torque of the joint axle can be increased without increasing the horizontal dimensions of the joint axle.

  • Patent number: 6524209
    Abstract: An absolute sensor 1 has a high speed side encoder 13 mounted on a high speed rotational shaft 6, a low speed rotational shaft 11 arranged coaxially with the high speed rotational shaft 6, a planetary gear mechanism 10 for reducing the speed of rotation of the high speed rotational shaft 6 and delivering the rotation of reduced speed to the low speed rotational shaft 11. The planetary gear mechanism 10 has a fixed sun internal gear a, a front stage planetary gear b, a rear stage planetary gear c, and an output sun internal gear d connected to the rear stage planetary gear c and low speed rotational shaft 11, wherein the planetary gears b and c are rotatably supported by an eccentric shaft portion 23 of the shaft 6. The planetary gear mechanism 10 can be constituted so that the input and output shafts are arranged coaxially, and can be made small with having a large reduction ratio in comparison with the conventional reduction mechanism comprised by spur gears.
