Title: Method for detecting spin turn position of unmanned vehicle
Inventor: TANAKA HIROSHI
IPC: G05D1/02
Filed: 1996-10-14
Abstract: PROBLEM TO BE SOLVED: To obtain a reliable spin turn end position detecting method by detecting an unmanned vehicle turn position by a turn end position detecting sensor which is arranged on an unmanned vehicle and detects its turn position. SOLUTION: The detection outputs of a sensor (movable type) 12 for a forward travel, a sensor (fixed type) 13 for a backward travel, and a turn end position detecting sensor 14 are inputted to a controller, which controls the travel direction, start and stop, attitude, etc., of the unmanned vehicle 10. The end of a spin turn is applied to the fixed type backward travel sensor 13 and a dedicated turn end position detecting sensor 14 is used for detection. The end is judged when the inputs to both the sensors become equal to each other and when this state is obtained, the unmanned vehicle 10 is stopped from turning. Consequently, the vehicle always stops on a guide line 15 (16) at the end of the spin turn, and further the inputs of two sensors are equal to each other, so it is judged that the unmanned vehicle 10 is stopping in parallel to the guide line 15 (16).

Abstract: PURPOSE:To automatically control the front end position of a suspended pipe even in deep sea and securely hold it at an aimed position. CONSTITUTION:An aimed position, azimuth, and depth are set in a presetter 11. A suspended pipe 1 is lowered from a float on the sea at a specified speed. The state of front end of this suspended pipe is detected by a sensor 4 and the detected signal is input in a comparator 12. the deviation between the detected figure and aimed preset figure is calculated in the comparator 12 and input in a fuzzy control logical unit 13 in which a total force and a moment force necessary for leading the suspended pipe end to the aimed position are computed basing on the deviated value by means of the fuzzy rule and the membership function. The processed result is output to the thrust distributor 14. The thrust distributor 14 allots the processed result of the fuzzy control logical unit 13 to drive a thruster 5 in order to correct the front end of suspended pipe 1 so as to coincide with the aimed direction.

Title: Signal detection circuit
Inventor: SUZUKI HIDEHIKO
IPC: H04M7/04
Filed: 1988-10-27
Abstract: PURPOSE:To enable detection of the presence of earth level of a chip lead by providing a comparator comparing the output voltage of a voltage divider dividing a ground voltage of a ring lead detected by a ring voltage detector into a factor of Rth/(Rth+RTR) with an output voltage of a chip voltage detector. CONSTITUTION:A chip voltage detector circuit 5 detects an earth level of a chip lead 2 and outputs its voltage VT to a comparator 8. Then a ring voltage detector 6 detecting an earth level of a ring lead 3 gives the earth level VR to the voltage divider 7, which outputs a voltage VR'(=VRXRth/(Rth+RTR)) to the comparator 8. The comparison depends on the relation of quantity between RTG/(RTG+RTR) and Rth/(Rth+RTR), the comparison does not affect a feeding voltage Vr of the ring lead 3 and the quantity of an internal resistance RR. As a result, stable earth detection is enabled.

The remaining two shims 25, 27 are placed symmetric to the first two shims with respect to the center plane in the axis direction of the cylindrical inner hole and then rotated by 90 deg. in the circumferential direction against the first two shims.  Thus the shims can be made an arbitrarily combination of (3,2) and (3,-2) harmonic function terms and this design produces only 7% of contamination compared to 70% by conventional design.
