Filed: 1991-02-21
Abstract: PURPOSE: To automatically select functions of a digital multi meter with a considerably small number of parts and update displays at a high speed even when an input signal type changes. CONSTITUTION: A signal type detector 17 and an A/D converter 16 are constituted of an ASIC. A comparison circuit 18 in the signal type detector compares an analog input signal with a predetermined threshold value, and stores a value related to the type of the input signal in a memory 20. A controller 22 reads the stored value and generates a corresponding function code. In consequence, the A/D converter converts the input signal properly. When the change of the input signal type is detected, a present measurement cycle is interrupted, and a next measurement cycle conforming to a changed input signal type is conducted. The controller generates a change alarm signal to inform that the input signal type is changed.

Abstract: PROBLEM TO BE SOLVED: To detect the damage of a water barrier sheet by providing a surface electrode above or below the water barrier sheet or providing surface electrodes on both sides thereof and supplying a current across the moving electrode moving along the upper part of the barrier sheet and the surface electrode to measure the change of the current. SOLUTION: A measuring part 6 comprises a moving electrode 7, a multimeter 8 and a recorder 9 and the moving electrode 7 is inserted into the specific region of the surface of protective sand 4 to record natural potential on the recorder 9. That is, in the measurement of natural potential, the potential difference between the moving electrode 7 above the water barrier sheet 3 and the surface electrode 2 is measured. If there is a damage part in the sheet 3, an electrical current supply state is formed between the surface electrode 2 and the moving electrode and the value near to the natural potential value of the surface electrode 2 is measured and, if the moving electrode 7 approaches the damage part, the natural potential value of the surface electrode 2 is measured.  If there is no damage part in the sheet 3, the surface electrode 2 and the moving electrode 7 become an insulated state and natural potential is not measured. This state is judged from the recorder 9 and the damage part can be specified.

Title: Hulling/rice milling device and control of roll gap for hulling device
Inventor: TOMABECHI MAKOTO
IPC: B02B7/00
Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To reduce the abrasion of rolls on a hulling device while preventing a faulty hulling operation from occurring by integrating hulling amounts after an operation to adjust a gap between the rolls prior to the supply of unhulled rice to the gap and adjusting the gap, if the integrated amount exceeds a specified amount. SOLUTION: A hulling device 10 is equipped with a pair of rolls 11 and a gap adjusting mechanism 60 for adjusting a gap between the paired rolls 11, and one of these rolls is rotated at a higher speed than that of another under the control at a constant speed ratio, so that the unhulled rice is fed at different high speeds while being pressed under a loaded condition and then is separated as the chaff and the unhulled rice. In this case, the hulling amounts of the unhulled rice after previously performed gap adjusting operation are integrated prior to the next supply of the unhulled rice to the gap between the paired rolls 11 of the hulling device 10, and if the integrated amount exceeds a specified amount, the gap between the rolls is controlled to be adjusted.  Thus, it is possible to reduce the abrasion of the rolls by performing this gap adjusting operation only when a rice milling operation and a hulling operation are conducted to some extent.
