Abstract: A body frame has a head pipe supporting a steering shaft, a main frame extended rearward of a vehicle body from the head pipe, and a down frame extended downward of the vehicle body from the head pipe, wherein the down frame includes a front down frame member forming at least a front portion of the down frame, and a rear down frame member forming at least part of a rear portion of the down frame, which are joined. The rear down frame member integrally has an arm supporting the main frame and a gusset reinforcing a joined portion of the main frame to the head pipe.

Abstract: The body frame has a head pipe 2 supporting a steering shaft, a main frame 3 extended rearward of a vehicle body from the head pipe 2, and a down frame 5 extended downward of the vehicle body from the head pipe 2, wherein the down frame 5 includes a front down frame member 70 forming at least a front portion of the down frame 5, and a rear down frame member 80 forming at least part of a rear portion of the down frame 5, which are joined. The rear down frame member 80 integrally has an arm 85 supporting the main frame 3 and a gusset 83 reinforcing a joined portion of the main frame 3 to the head pipe 2.

Abstract: A self-traveling crusher which enables a worker to easy carry out the operation for removing the reinforcing bars that are entangling, jamming and staying between a crushing device and a discharge conveyer relying on a simple structure without transferring the crushing device to an upper part of the machine body. The self-traveling crusher comprises a hopper into which a material to be crushed will be thrown, a crushing device for crushing the material to be crushed that is thrown in, and a discharge conveyer which is positioned at an end on one side thereof under the crushing device and is extending on the other end side thereof outward of the machine to deliver the crushed material to a predetermined height, wherein the discharge conveyer is mounted on the machine body so as to swing up and down with an end on the side of the crushing device as a center, and is supported at an end on the other side thereof by the machine body via lifting means.

Abstract: This invention configures a semiconductor memory device in the following manner. The semiconductor contains a first memory part and more than one redundant circuit that is used when the first memory part is faulty, and each redundant circuit memorizes in its status memory part whether a second memory part which becomes a spare cell is in a not-in-use status, in an in-use status or in an out-of-use status, which means that a failure exists in the second memory part. If a second memory part is in the out-of-use status, its access is prohibited, and the other second memory part without a failure is accessed. With this configuration, when a spare cell is confirmed to have a failure after the spare cell is programmed, the spare cell is put in the out-of-use status, thereby preventing the spare cell from being accessed. Consequently, the yield of the semiconductor device is increased.
