Filed: 1985-07-18
Abstract: PURPOSE:To secure the straight drive of an underwater robot within a pipeline with no meandering movement by controlling a driving device so that the deviation is equal to zero between the rolling angle of the robot main body detected by a sloping angle detector and a set rolling angle. CONSTITUTION:An underwater robot main body A moves up toward the side part of the inner wall of a pipeline which rises up with a curve when the driving direction of the robot has the deviation. Thus the rolling angle of the main body A is gradually increased. When the deviation is produced between the rolling angle detected by a sloping angle detector 11 and that set by a rolling angle setter 27, an operating signal (a) having a certain value is delivered from an arithmetic part 22. An operating control part 23 controls the driving devices 3 and 4 so that the value of the signal (a) is equal to zero. Thus, the driving direction of the robot main body A is corrected. As a result, the robot A moves straight with its positure kept in response to the rolling angle (usually set at zero) set at a rolling angle setting part 21.

Title: Electrode for electric discharge machining
Inventor: MORI MASAHIRO
IPC: B23H7/22
Filed: 1986-07-04
Abstract: PURPOSE:To reduce an unmachined part and improve the efficiency of electric discharge machining by inclining at least one end of a cutting oil feed passage within an electrode toward a machining surface for electric discharge. CONSTITUTION:Electric discharge machining is carried out on proper timing lowering of an electrode 5 for electric discharge having an inclined part 6k wherein the end of a cutting oil feed passage 6 is inclined to a machining surface 5k. In this case, an arc discharge takes place between the tip of a primary unmachined part 2m and the inner wall of the inclined part 6k. As a result, the unmachined part 2m is constrained to be very low due to height determined by the diameter of the inclined part 6k and the inclination angle thereof. Therefore, machining time by an after-treatment device is substantially reduced and electric discharge machining efficiency can be improved. Also, the unmachined part 2m can be eliminated by turning the electrode 5.
