  • Publication number: 20200298422
    Abstract: Provided is a robot equipped with two joint parts attached to an end of an arm in a coupled state. For example, in a joint part of a robot, a motor and a reduction gear are housed in a case, and an output-side member having a flange is fixed to the output shaft of the reduction gear. An opening that opens in the direction orthogonal to the axial direction of the output shaft of the reduction gear is formed in the case. A planar attachment face orthogonal to the opening direction of the opening is formed in the opening. The robot is provided with a plurality of biaxial joint units comprising two joint parts. In the robot, the attachment face of the case of one joint part constituting a biaxial joint unit is fixed to the flange of the other joint part either directly or via a coupling member.

  • Patent number: 10031223
    Abstract: In a vehicle control apparatus, a rear side detecting unit, mounted to an own vehicle, detects another vehicle that is present in a first area behind and to a side of the own vehicle. A time acquiring unit, mounted to the own vehicle, acquires a first time that is an estimated time at which a front approaching vehicle will arrive at the first area. The front approaching vehicle is another vehicle that is relatively nearing the own vehicle from ahead of the own vehicle. A sensitivity setting unit, mounted to the own vehicle, sets a detection sensitivity of the rear side detecting unit to the other vehicle in at least a part of the first area in such a manner that the detection sensitivity during a predetermined period set based on the first time is higher than the detection sensitivity during a remaining period other than the predetermined period.

  • Patent number: 9998196
    Abstract: An antenna device includes: antennas; magnetic oscillation element units converting electrical energy to high-frequency power; and a modulator outputting electrical energy input from outside to at least two magnetic oscillation element units, with a time difference to differentiate phases of high-frequency power converted from electrical energy by at least two magnetic oscillation element units. The magnetic oscillation element units respectively include a pair of electrodes, and further include, between the pair of electrodes, a PIN layer, a free layer, and an intermediate layer. A resistance value of an element configured by the PIN, free and intermediate layers changes according to the angle between the magnetization direction of the PIN layer and the magnetization direction of the free layer. The antennas transmit electromagnetic waves to open space outside the magnetic oscillation element units with the supply of high-frequency power.

  • Patent number: 9547077
    Abstract: In a dual-frequency CW radar apparatus, first/second beat signals that include reflection components of radar waves conforming to transmission signals of first/second frequencies are generated for each antenna element and the generated signals are Fourier transformed. A power spectrum average of the beat signals is used as a basis for the detection of a peak frequency fp corresponding to the frequency of the reflection components. A second eigenvalue ?2 of a correlation matrix: Ry=(½)·[y1,y2][y1,y2]H is calculated, the matrix being based on first received vector y1/second received vector y2 having elements that are Fourier transformed values of the peak frequency fp. Based on the magnitude of the eigenvalue ?2, whether or not the reflection components corresponding to the peak frequency fp are synthetic components of the reflected waves from a plurality of targets is decided.

  • Patent number: 8686893
    Abstract: A signal processing unit in a radar device calculates a change amount Y (=log(P)?log(Pb)) between a power P of a current arrival echo and a power of a previous arrival echo arrived before an observation period TSW. A memory unit in the radar device stores, every type of objects, a probability distribution of the change amount Y calculated from the arrival echo from the object. On the basis of the calculated change amount Y and the probability distribution, the signal processing unit determines a probability Pr to obtain the change amount Y every type of object, and determines that the object having the maximum probability Pr is the object which transmits the current arrival echo.
