Title: Trough digging apparatus
Inventor: BOLLINGER KARL
IPC: E02F5/08
Filed: 1987-09-25
Abstract: The invention relates to a motor-driven milling machine construction for cutting trenches in the ground, in which there are two rotating semi-drums with cutting tools at their periphery. The drums are mounted on a central support. The sole function of the motor is to transmit a rotational torque to the semi-drums without transmitting any other forces. The stress exerted on the cutting tools is directly transmitted to the central support without going through the motor frame.

Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To specify a failure point and discover the failure in its early stages by storing a current value when a normal electronic substrate carries out a reference operation, and comparing the value with a current value when an electronic substrate constituting an electronic apparatus to be inspected carries out a reference operation. SOLUTION: The diagnosing system for electronic apparatus comprising an electronic substrate where a plurality of electronic parts are mounted includes, e.g. a power source 2 for supplying a current to the electronic substrate 1, a memory 9 for storing values of the current, and the like. A substrate 1 which is confirmed not to fail makes a preliminarily set reference operation under the control from a CPU 6 and the current of the power source is stored in the memory 9. Thereafter, the power source current is measured for every substrate which is doubted to fail and compared with the value in the memory 9. The failure substrate can be judged from a change in current value.  When the system is driven in a preliminarily set sequence and the power source current is stored in time sequence, since the power source current can be measured in a larger number of operation states, the failure detection rate is high.

Abstract: PURPOSE:To uniformly apply real finger-pressure operation to each effective spot, by applying finger pressure by the projecting operation of a treatment element for finger-pressure due to a finger-pressure drive mechanism while moving said treatment element at the pitch corresponding to the size thereof. CONSTITUTION:When an automatic course switch is operated, operation for moving a treatment element 1 up and down along a backrest is added to finger-pressure operation. A pitch switch S3 is turned ON when the slits provided to a gear are optically detected. Since the length of each of the slits is equal to the length between the slits and the sum of the lengths of both of them is made almost same to the diameter (d) of the bone member 12 of the treatment element 1, the up-and-down moving quantity of the treatment element 1 from the ON-state to the ON-state of the pitch switch S3 or from the OFF-state to the OFF-state thereof becomes almost equal to the diameter (d) of the bone member 12 of the treatment element 1. Therefore, the treatment element 1 certainly applies finger-pressure to the effective spots densely present across the backbone in a left-and-right symmetric state and, especially, since the size of the treatment element 1 is almost set to the size of the thumb and the interval between the effective spots is near to said size, the accurate finger-pressure to the effective spots is obtained.
