Title: Evaluating method fro strength of granulated material
Inventor: YAMAMOTO TETSUYA
IPC: G01N3/00
Filed: 1990-06-07
Abstract: PURPOSE:To make it possible to perform accurate evaluation by filling a bottomless container with granulated material, applying a specified load, and moving the container on a rough floor surface. CONSTITUTION:A part of granulated material which is granulated in a granulating step is sampled. The granulated material 3 having the diameter of the granule to be measured is sieved. A bottomless container 2 on a rough floor surface 1 is filled with the granulated material. A load 4 is mounted on the upper part. In filling, the granulated material 3 is made to fall freely from the specified height, and the filling height is uniformly adjusted. The bottom area of this container 2 is set so that the umber of the granulated materials 3 which are in direct contact with the floor surface 1 is many. Then, a wire 5 which is connected to the container 2 is wound with a motor 6, and the granulated material 3 is moved together with the container 2. Thus, the granulated material 3 at the lowermost layer is rotated with the frictional resistance with the floor surface 1 and collapsed. This action sequentially rises to the upper layer. The strength of he granulated material 3 is evaluated by measuring the amount of the collapse.

Abstract: PURPOSE:To allow a driver to take the most suitable action quickly by detecting an irregularity when it occurs so as to indicate the occurrence of the irregularity. CONSTITUTION:When a car height raising control or a car height lowering control is performed, the output of an NOR gate NOR2 is turned to (H) and the output of an OR gate OR4 is truned to (H), then a transistor Tr3 is turned on and a lamp LP is lighted. If at least one of irregularity detection circuits detects an irregularity, the output of an OR gate OR1 is turned to (H) and an AND gate AND6 is opened, then frequency divided clock pulses from a clock generator are applied to the base of the transistor Tr3 through the AND gate AND6 and OR gate OR4. Therefore, the transistor Tr3 is turned on and off, thus indicating the occurrence of an irregularity.

IPC: G02B7/28
Filed: 1988-06-17
Abstract: PURPOSE:To speedily detect that a driving condition goes to abnormal by an inexpensive, simple structure and to prevent each mechanism from being damaged by excessive load by monitoring the changing amount of a focal length per a prescribed time of interval, judging the amount as abnormal driving when the amount is below a reference value, and stopping the drive of a photographing lens. CONSTITUTION:When a changing amount monitoring means 18 decides that the changing amount of previous current focus information per prescribed time of interval is below the reference value, the fact is translated into that a moving barrel 5 fails to advance and retreat somehow, and a motor control means 11 acts to stop the drive of the moving barrel 5 supporting the photographing lens. Since a changing amount detecting means 17and the changing amount monitoring means 18 monitor the changing amount of a focal length per prescribed interval in such a way, abnormal driving can be detected speedily under the simple constitution. Even if a power source for driving a motor 10 fluctuates and environmental conditions change, etc., only abnormal driving can be detected appropriately without being affected by such changes.
