Title: Equipment for generating paraboloid of revolution
Inventor: IWATA KAZUAKI
IPC: B23Q27/00
Filed: 1981-03-12
Abstract: PURPOSE:To provide an accurate paraboloid of revolution without leaving any uncut portion on a workpiece on the axis of its rotation, by effecting control to move the workpiece and a tool relative to each other in the directions of the axes of rotation of the tool and the workpiece so that their displacements comply with a prescribed relationship formula. CONSTITUTION:The line of intersection of a paraboloid of revolution, which is expressed as z=1/4alpha(x<2>+y<2>) where alpha denotes the focal distance, with an arbitrary inscribed ball, whose center is denoted by Oc, is a circle MM'. A line OcP extending on the center Oc and inclined at an angle of theta to an axis (z) is used as the axis of rotation of a tool. A line PQ is used as the radius of rotation of the tool. When a workpiece is rotated once around the axis (z), portions QQ', SS' of the inscribed ball are generated. When some of the generated spherical surface portions includes the circle MM', a portion MM' of the paraboloid is cut. The center Oc is moved along the axis (z) to the center of the ball located in contact with the vertex O of the paraboloid. At the same time, the length of the line OcP is altered. As a result, the paraboloid of revolution MOM' is generated. The relationship between the line OcP=a and another line OOc=b is defined by a formula. The positions of axes A, B of the generating equipment are controlled to conform with the formula when the workpiece is rotated.

Title: Vacuum circuit-breaker
Inventor: YOKOKURA KUNIO
IPC: H01H33/66
Filed: 1990-02-19
Abstract: PURPOSE:To surely prevent switching surge generating and lower the cost of a circuit-breaker by detecting current running in a main circuit of an electric power system opening a vacuum circuit-breaker at a specified phase and composing only one of contacts on fixed side and movable side of a material having low current shutting value. CONSTITUTION:When an output of a transformer 1 having the same phase as a main circuit current is input to a pulse generating circuit 2, the circuit 2 generates a pulse at zero point of the input signal. The pulse provides half- wave rectification for input to a driving pulse generating circuit 4. When a circuit-breaker tripping signal is input to the circuit 4 from outside, the circuit 4 generates a driving pulse and the tripping signal is provided to the operation system of a vacuum circuit-breaker 6 from a tripping circuit 5 after prescribed period. Consequently, a contact in the fixed side 13 and a contact in the movable side 14 of the circuit-breaker 6 can be opened at a specified phase of current running in the main circuit. When only one of the contacts 13, 14 on a cathodic point side is composed of a material having a low current shutting value, the current shutting value becomes low, Switching surge generation is thus surely prevented and the cost is lowered.
