  • Publication number: 20190168544
    Abstract: A tire is provided with a tread pattern comprising a series of a number N of tread design units arranged repeatedly and circumferentially of the tire in a sequence and having a number m of different circumferential lengths. A first pulse train is defined by viewing the tread design units as pulses arranged in the same sequence as the tread design units at intervals which are defined by the circumferential lengths of the corresponding tread design units expressed in term of a ratio to one of the number m of different circumferential lengths. A maximum value Pmax of amplitudes P(k) (k=order from 1 to 2N) of frequencies obtained by Fourier transforming the first pulse train is limited to specific values. The amplitudes P(k) and P(k+1) of every two of the adjacent orders (k) and (k+1) do not satisfy a condition that both of the amplitudes P(k) and P(k+1) have values of 2/3 or more times the maximum value Pmax.

  • Publication number: 20190168545
    Abstract: A tire has a tread pattern comprising a series of a number N of tread design units arranged repeatedly and circumferentially of the tire in a sequence. The tread design units have at least two different circumferential lengths. Viewing the tread design units as pulses, a pulse train is defined. Magnitudes of the pulses are proportional to the circumferential lengths of the tread design units. The average of the magnitudes corresponding to the different circumferential lengths is limited to 1.00. Maximum value Fmax of amplitude F(k) of k-th order (k=1 to 2N) of frequencies obtained by Fourier transforming the pulse train is limited to be 4.52?0.0125 N. The amplitudes F(k) and F(k+1) of every two of the adjacent orders (k) and (k+1) are limited so as not to satisfy a condition that both of the amplitudes F(k) and F(k+1) are 2/3 or more times the Fmax.

  • Patent number: 10232509
    Abstract: A robot apparatus includes a manipulator, a teaching apparatus, and a control apparatus. The manipulator includes a hand and an arm having a plurality of joints. The teaching apparatus teaches operation of the manipulator. The control apparatus controls the manipulator based on a control signal from the teaching apparatus for causing the manipulator to operate in a predetermined operation direction. In a case where the predetermined operation direction has been checked, the control apparatus transmits, to the manipulator, a control signal for causing the manipulator to operate at a regular speed. In a case where the predetermined operation direction has not been checked, the control apparatus transmits, to the manipulator, a control signal for causing the manipulator to operate at a speed lower than or equal to a safety speed that is set based on the regular speed.

  • Patent number: 9989687
    Abstract: A wave plate capable of increasing a birefringence quantity and being made into a thin film, and a method of manufacturing the wave plate. The wave plate includes a substrate, whereon convex portions and concave portions are formed with a period less than or equal to the wavelength of light that is used therewith, columnar portions, wherein fine grains of a dielectric material are layered by oblique vapor deposition of a dielectric material from two directions, in a columnar shape on the convex portions in the vertical direction relative to the surface of the substrate, and interstices that are located on the concave portions and disposed between the columnar portions. Using birefringence from the fine grains of the dielectric material and birefringence from the concave/convex portions of the substrate allows increasing the birefringence quantity and making a thin film.

  • Publication number: 20170361464
    Abstract: A robot apparatus includes: a robotic arm provided with a robotic hand capable of changing its position and its orientation by using joints; a visual sensor which measures a position or an orientation of a gripped object gripped with the robotic hand at a measurement teaching point; and a control device. The control device controls the position or the orientation of the gripped object when the gripped object is attached to an attachment target object at a corrected teaching point corrected based on a measurement result by the visual sensor. In this case, the control device determines a measurement teaching point, where the measurement with the visual sensor takes place, such that a driving direction of each of the joints from the measurement teaching point to the corrected teaching point is set to a definite driving direction.

  • Publication number: 20170242684
    Abstract: A controller corresponding to production equipment, requiring upgrade can be selected automatically, thereby reduction in operating rate can be reduced. When software is upgraded, version upgrade software relating to a predetermined action description and version information are transferred to a controller management apparatus (S1). A version change determination unit selects a controller including the predetermined action description described in the version information (S2 and S3). The selected controller downloads the new version of software to change the software (S4 and S5) after stopping operation of the production equipment. On the other hand, a controller not selected does not download the software, and the operation of the production equipment is not stopped.
