Abstract: PURPOSE:To uniformize erosion of a target material arranged on a permanent magnet and to prolong the service life thereof by constituting the inner and outer magnetic poles having reverse polarities of a soft magnetic material and arranging the permanent magnet which is low in the central part and formed gradually high toward both sides between both magnetic poles. CONSTITUTION:Both an inside magnetic pole 2 and an outside magnetic pole 3 which has reverse polarity and surrounds it are arranged to the surface side of a target material 1. Plasma is made high density by forming a leakage magnetic filed to the surface side of the target material 1. The target material 1 is sputtered by the ions at high velocity and the sputtered target material is applied to a material to be worked. In the above-mentioned planar magnetron sputtering device, both magnetic poles 2, 3 are constituted of a soft magnetic material and arranged on a base plate 4 constituted of a nonmagnetic material. Furthermore a permanent magnet 5A is arranged between both magnetic poles 2, 3 which has magnetization of the horizontal direction and is low in the central part and formed gradually high toward both sides. Thereby the componential gradient of the leakage magnetic filed vertical to the target material 1 is reduced in the central part and made large near to both magnetic poles 2, 3. Therefore generation of local erosion of the target material 1 is prevented and homogeneous film formation is enabled.

Title: Electric field operated proximity fuse
Inventor: RICHIYAADO TOOMASU TSUIINBA
IPC: F42C13/04
Filed: 1990-11-22
Abstract: PURPOSE: To restrict explosion of a warhead until encountering a flying target, by a method wherein an arming signal generated in response to a voltage of a probe as a missile approaches into an electric field inherently associated with the flying target is applied to a first detecting part to detonate the warhead. CONSTITUTION: Current proportional to the voltage of a probe 24 to be generated as a missile approaches an electric field of a target is converted to a voltage of a signal and amplified to be supplied to a microprocessor 30. When an attack target is captured, the microprocessor 30 outputs an arming signal to make a fuse 36 of a warhead of the missile ready for operation. An RF receiver 38 of an active type proximity searching part transmits a signal via a radar antenna 26 and receives a signal returned from the target 10 to generate a signal for triggering the fuse by a microprocessor 40, which is applied to the other output side of a coincidence gate 34. But a gate 34 will not operate until the missile enters a range of a target detecting distance of a passive type detecting part 29, thereby preventing earlier detonation of the fuser 36.
