Abstract: A walking assist device having a load transmit portion, a leg link connected to the load transmit portion, and a driving source capable of driving the leg link in a direction to raise a seat member, so that at least a partial weight of a user may be supported by the leg link through the load transmit portion. An electric component to be used for controlling the driving source can be mounted on the walking assist device without degrading the compactness of the walking assist device. At least a part of the leg link is constituted of a cylindrical link member in which at least the electric component, such as a motor driver to be used for the control of the driving source, is partially housed. The walking assist device also includes a heat transfer member for absorbing the heat of the electric component by the cylindrical link member. The heat transfer member is thermally connected to a side plate of the cylindrical link member directed toward the side opposite to the leg of the user.

Abstract: A walking assistance device has a leg link formed by connecting a first link member and a second link member through a third joint assembly. A force generated at the leg link by driving the third joint assembly is transmitted to the body of a user. The walking assistance device enables the user to deeply squat by making the third joint assembly highly bendable. The third joint assembly has with a joint link member, a first joint which connects the joint link member and a first link member, and a second joint which connects the joint link member and the second link member. The walking assistance device is further equipped with a drive source which imparts a torque in a stretching direction to the first joint, and an elastic member which elastically holds the second joint in a predetermined stretched state until a predetermined value or more acts thereon.

Abstract: An actuator (91) is reduced in weight without impairing a walking assist function, and this reduces the inertial moment of a leg link (3). A drive crank arm (92) on the output shaft of the actuator (91) and a driven crank arm (93) fixed to a second link portion (7) so as to be concentric to the joint shaft of a third joint portion (8) are connected to each other via a connection link (94). The connection link (94) is placed so that a line connecting a pivot portion (94a) at which the drive crank arm (92) is pivotally mounted and a pivot portion (94b) at which the driven crank arm (93) is pivotally mounted obliquely crosses a line connecting the output shaft of the actuator (91) and the joint shaft of the third joint portion (8).

Abstract: A walking assistance device having a leg link connected to a load transmit portion via a first joint and to a foot attachment portion via a second joint, and having an intermediate third joint moving such that a distance between the first joint and the second joint is variable; a drive source for the third joint; and a battery for the drive source. When in an upstanding position, force in the forward-backward direction is prevented from acting on the load transmit portion to enhance stability. Also, a moment of inertia of the leg link is decreased to curtail a load applied to the leg of the user. The drive source and the battery are located at positions higher than the third joint, and when the user is in an upstanding position, a plane passing through the second joint lies between the drive source and the battery.

Abstract: In walking assistance device, a force detector (21) is provided between thigh retaining member (9) that directly retain the thigh of the user and a thigh support member (2) that is actuated by an actuator (TA1) provided in hip coupling portion. Thereby, the load acting on the hip coupling portion can be accurately detected, and the output of the force detector can be favorably used for the purpose of controlling the actuator so as to minimize the force that is applied to the thigh of the user. In particular, to the end of providing a suitably rigidity to the thigh retaining member so that the force produced by the actuator may be evenly applied to the entire thigh, and facilitating the effort required for the wearer to wear the walking assistance device, the thigh retaining member comprises a base portion (9a) connected to the thigh support member and two pairs of resilient arms (9b, 9c) extending laterally from either side of the base portion so that the thigh retaining member generally defines a shape of letter-C in plan view.

Abstract: An antenna device comprises an array antenna having a plurality of transmitting planar antenna elements and a plurality of receiving planar antenna elements, a transmission selecting circuit for selecting at least one of the transmitting planar antenna elements, a transmitting circuit for transmitting a signal to the selected at least one transmitting planar antenna element, a reception selecting circuit for selecting at least one of the receiving planar antenna elements, and a receiving circuit for receiving a signal from the selected at least one receiving antenna element. By selecting the planar antenna elements exclusively for transmission or reception, it becomes possible to radiate or absorb (receive) a main beam in or from a direction corresponding to the respective planar antenna element, thereby enabling more minute switching of the main beam directions and improving the directional resolution of the antenna device. Further, by providing the transmitting and receiving planar antenna elements separately, it becomes possible to prevent the deterioration of the reception sensitivity due to the leakage of part of a received signal into a transmission system of the antenna device. An antenna system employing the antenna device is also disclosed.

Abstract: An FM radar system includes an amplifier for amplifying the beat signal at an amplification factor varying with the frequency, and a level correcting device for correcting a spectrum level of an amplified signal or a spectrum level of a signal generated based on the amplified signal, into a spectrum level obtained when the beat signal is amplified without involving Doppler shift caused by a velocity of the target relative to the FM radar system. By virtue of the correction performed by the level correcting device, it becomes possible to obtain a real spectrum level which is observed when the target is stationary or fixed in position relative to the radar system.
