Title: Method for inspecting grindstone for grinding mill roll
Inventor: SHIRAI YASUTA
IPC: B21B28/04
Filed: 1984-03-21
Abstract: PURPOSE:To improve roll grinding efficiency by inspecting a grindstone by comparing an estimated grinding quantity obtained from the product of a detected load and a grinding time with an actual grinding quantity obtained from the difference between the profiles before and after grinding. CONSTITUTION:A grinding wheel 4 is rotated by supplying a hydraulic pressure by a hydraulic motor to a motor 5 used for driving the wheel 4. The wheel 4 is brought into press contact with a roll 2 through a pulse motor 12 and an eccentric body 11 to perform grinding. An estimated grinding quantity is indicated by the product of the difference between the hydraulic pressures at the time of loading the motor 5 and that of noloading and the holding time of whestone. The estimated grinding quantity is compared with an actual grinding quantity obtained from the difference between the profiles measured before and after the grinding respectively to rapidly seize the abnormality such as the clogging of whestone when the difference between both quantities is abnormally large or small. Accordingly, the roll grinding efficiency is improved by rapidly dealing with the abnormality.

Abstract: PROBLEM TO BE SOLVED: To facilitate removal of a transportation container from a nested state to remarkably improve operativity by placing a support leg and a pocket adjacent to a center between a center of the container and an end of the container and also by forming the pocket to be wider than the support leg. SOLUTION: In a stackable and nestable transportation container 11 wherein containers can be nested by rotating one of the containers by 180 degrees, support legs 21 to 52 protruding on an external face of a peripheral wall and pockets 24 to 55 where the support legs can enter at the time of nesting are placed adjacent to a center between a center of the container and an end of the container. In addition, the pockets 24 to 55 are formed to be wider than the legs 21 to 52 so that lower ends of the support legs 21 to 52 may not come into contact with sides of the pockets 24 to 55 of a lower container when an end of an upper container is raised while the containers are nested. Thus only by slightly lifting an end of the container 11 and sliding forward, it can be taken out.

Title: Pedal displacement control structure of vehicle
Inventor: ONO MASAHIRO
IPC: B62D25/08
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To control the displacement of the tread of a vehicle pedal when an external force over the specified level is applied to the front part of the vehicle. SOLUTION: A pressing part 80 installed on a steering support 76 is located behind the pedal supporting part 56 of a brake pedal 10. When an external force over the specified level is applied to the front part of a vehicle, the pedal supporting part 56 displaced backward is pressed by the part 80 approx. to ahead of the vehicle, so that the brake pedal 10 makes rotational displacement round a rotary shaft approx. to ahead of the vehicle. A restriction block 82 is installed on the pedal supporting part 56, and therefore, after the foremost of the pressing part 80 contacts with the pedal supporting part 56, the tendency of the pressing part 80 to make relative displacement (dislocation) caused by the reactive force to the pressure approx. toward under the vehicle can be restricted by the restriction block 82.
