Title: Deep drawing die
Inventor: TANIMA RETSU
IPC: B21D24/12
Filed: 1994-02-09
Abstract: PURPOSE:To prevent the development of crack caused by press-forming by shifting a gap forming member to the direction approaching a punch while guiding to a sloping surface for adjusting the gap to gradually widen the gap between a holding member and a die. CONSTITUTION:According as the die 12 is approached to the punch 14, the gap forming member 28 together with a blank holder plate 22 are pushed down with the die 12. The gap forming member 28 is guided with the sloping surface 40 for shifting a fixed cam 25 at the abutting surface 41 and the sloping surface 26 and the sloping surface 38 as the sloping surface for adjusting the gap of the blank plate 22, respectively and shifted to the direction approaching the punch 14 in a cut-off part 26 of the die 12. In this result, the prescribed deep- drawing can be executed to a material 32 to be worked while gradually widening the gap 29 by the quantity corresponding to almost the increasing quantity of a plate thickness in the outer peripheral part of the material 32 to be worked.

Title: Ultrasonic contact sensor and autonomous type moving robot equipped therewith
Inventor: KONDO SHINJI
IPC: G01S15/02
Filed: 1989-01-25
Abstract: PURPOSE:To detect the position of contact of an object precisely by constructing the contact sensor of a waveguide, an ultrasonic element, an ultrasonic transmission-reception circuit, a timer circuit and a distance calculating means. CONSTITUTION:An ultrasonic wave is transmitted inside a waveguide 1 from an ultrasonic element 2 by an ultrasonic transmission-reception circuit 3, and it is reflected ordinarily on a closed surface of the waveguide 1 and received as a reflected wave by the ultrasonic transmission-reception circuit 3 through the ultrasonic element 2. A time T from transmission of this ultrasonic wave to reception of the reflected wave is measured by a timer circuit 4. This time T is fixed. When the outer wall of the waveguide 1 is pressed by fingers, for instance, in this constitution, the waveguide 1 is closed up and the ultrasonic wave transmitted is reflected on the surface thus closed and turned to be the reflected wave. Therefore the aforesaid time T is shortened. A distance calculating means 5 calculates from this time T a distance from the ultrasonic element 2 to the surface covered with the fingers, and thus the position of contact of the fingers can be detected linearly with excellent precision.

Filed: 1982-02-04
Abstract: PURPOSE:To enable to obtain a permanent rotation, by converting the gravity ratio on the right side and on the left side into rotational energy through utilization of the gravity, levers and gears. CONSTITUTION:By turning gravitation take-out arms 13 to the right with spherical heavy substances 15 being put on one of rails 17 at its end portion, the spherical heavy substances 15 are taken up one by one and raised upward by scooping arms 11. At the time before the third substance 15 is taken up by the arm 11, a preceding arm 11 is located on the right side and begins to descend. In this state, four gears 3 come into mesh with a toothed rail simultaneously, and the substance 15 rolls on a rail 13 and stops at the top of the same. Since, in this state, the gravity is multipicated by several times by the principles of the lever and fulcrum, the arm 11 is moved downward. In doing so, the next arm 11 takes up a substance 15 and is moved upward while holding the substance 15 at its root portion, with rollers 9 being guided by a rail 8. By thus increasing the leverage at the time when the substance 15 is raised upward and when it is moved downward, it is enabled to obtain a strong turning force and to continue rotation permanently.
