Title: Moving object
Inventor: IGUCHI NOBUHIRO
IPC: B62D57/024
Filed: 1980-10-02
Abstract: PURPOSE: To miniaturize a moving object, by a method wherein, utilizing a shape memory material which self-moves by providing with a given heat condition, a spring, which energizes so as to deform the shape memory material from a memory shape, is mounted.  
     CONSTITUTION: If around a top part C of a shape memory alloy 1 is heated, it trys to restoes to a stored straight shape, and this widens a distance between the points A and B against a spring 3. The point B, then, stays at the initial position almost as it is, but the point A moves ahead by a distance l 1 . Then, if the alloy stops being heated, the shape memory member 1 starts to cool, the member 1 is deformed by the spring 3, and the distance between the points A and B is narrowed again. The point B moves ahead thereupon, and the point A moves backward by a slight distance l 2 . The distance l 1  is longer than the distance l 2 , and as a result, the repetition of the above cycle causes moving-forward of a moving object by a distance of l 1  - l 2 . Or, this eliminates the need for a drive device for performing a movement and permits the miniaturization of a device.

Abstract: PURPOSE:To uniformize the breadth of the roughly rolled material, by computing and controlling the roll gap corresponding to the variation in the distance, from the front (rear) end of the rolled sheet under an edging pass to edging roll, according to the formula representing the fluctuation in the breadth of the rolled sheet as the function of the distance from the front (rear) end of the rolled sheet. CONSTITUTION:When the rolled material 1 arrives at the material's front end detector 7, the function generator 6, which has been waiting at the edger roll gap of the reference value, receives a signal from the detector 7, and delivers an output signal for DELTA (0) computed by placing x=o on the left and the right. The roll gap adjuster 5 adjusts the roll gap so as to change only DELTA (0) from above stated reference value, and waits for the feed-in of the front end of the rolled sheet into the roll. The change in the (x) with progress of following rolling work is detected by the revolution counter 8, and the distance from both ends of the rolled sheet is computed by the computer 9. As a result, the function generator 6 delivers an instruction for the renewed value of the edging DELTAx, on purpose to continue the controlling of the roll gap.
