Abstract: Provided is a leaky coaxial cable in which a plurality of slots 1 for forming a leak electromagnetic field are arranged in a string shape in an outer conductor of the coaxial cable. The pitch interval of the slots 1 is periodically changed in the axial direction. The periodical change of the pitch interval of a slot portion changes according to a sinusoidal function, a quadratic function, or other functions.

Abstract: The lift arm of a skid steer loader according to the present invention has a simple structure. A pair of left and right lift arms each has a first arm portion and a second arm portion. The first arm portion is made as an elongated member from components made from plate metal or the like, and its base end is rotatably fitted to a support portion which projects upwards at a rear portion of the main body of the loader. In this second arm portion, a connection portion, an attachment fitting portion, a horizontal load bearing portion, and an actuator fitting portion and so on are integrally formed as one member from cast metal. Furthermore, a hollow portion is formed in the interior of this second arm portion, extending from an approximately intermediate portion thereof to its base end.

Abstract: A lift arm for a skid-steel loader, in which a pair of right and left lift arms are divided in two so that they are constituted as first arm portions and second arm portions. Each of the first arm portions is constituted as a long member which is constituted from a sheet metal material and a hollow portion is formed from a proximal end to a front end of the first arm portion. Reinforcing plate-shaped bodies are fixed on both side faces from a central portion to the front end. Each of the second arm portions is constituted from a plate-shaped body and constituted between a front wheel and a loader main body so as to be inserted loosely. With this structure, it is possible to provide the lift arm which enables an entire length of the skid-steer loader to be shortened.

Abstract: A lift arm for a skid-steel loader, in which a pair of right and left lift arms 6, 6 are divided in two so that they are constituted as first arm portions 21 and second arm portions 22. Each of the first arm portions 21 is constituted as a long member which is constituted from a sheet metal material and a hollow portion is formed from a proximal end to a front end of the first arm portion. Reinforcing plate-shaped bodies 25A, 25B are fixed on both side faces from a central portion to the front end. Each of the second arm portions 22 is constituted from a plate-shaped body and constituted between a front wheel 3A and a loader main body 2 so as to be inserted loosely. With this structure, it is possible to provide the lift arm which enables an entire length of the skid-steer loader to be shortened.

Abstract: A radar apparatus is provided that can correctly extract the necessary point for a determination related to the safe travel of one's automotive vehicle among objects such as automotive vehicles moving at an angle in front and constructed objects. The radar apparatus of the present invention provides antennas that transmit beams in a plurality of directions and receive the reflected waves from objects as received signals. The objects that generated these reflected waves are detected.
