Title: Zoom controller
Inventor: IZUMI YASUHIRO
IPC: G02B7/10
Filed: 1989-05-16
Abstract: PURPOSE:To limit a zooming operation range without providing a lens main body with a zooming range limiting mechanism which causes an increase in lens weight by providing a variable range controlling means which limits the operation range of zooming. CONSTITUTION:A rotary ring 4 is free to rotate clockwise and counterclockwise about a controller main body 1 concentrically with a shaft 2b when a fixation ring is loosened and when the rotary ring 4 is rotated forward or backward, a stopper 6 moves forward or backward associatively and continuously in a spiral groove 1b within the entire-length range between both ends S0 and St0 of a spiral groove 1b along the spiral groove 4a while controlled by a radial linear groove 4a. For the purpose, the rotary ring 4 is rotated to a desired rotational angle position and stopped from rotating at the position with a screw to set a stopper 6 at, for example, a position St', and then the movable range of a sphere 3 along the spiral groove 1a is limited between a position W0 and a position St' as the set position of the stopper 6. Consequently, the zooming operation range can be limited.

Title: Magnetizing method of rare earth magnet
Inventor: ISHIBASHI TOSHIYUKI
IPC: H01F13/00
Filed: 1985-06-06
Abstract: PURPOSE:To realize saturated magnetization even under the magnetic field of low magnetization, by heating and magnetizing a rare earth magnet which comprises rear earth metal, iron, and boron. CONSTITUTION:A rare earth magnet comprising R-Fe-B as basic composition is heated at the temperature of 50-200 deg.C for magnetization. When R-Fe-B magnet is magnetized by high-temperature heating, with coersive force being low, saturated magnetization can be realized under the magnetic field of low magnetization. Replacing a part of Fe by Co enables both a curie temperature and temperature coefficient of Br to be improved, and besides magnetic performance, corrosion-proof property, and the like can be also improved with replacement by other group of transition metals. Thus, with the magnetization being low, the magnetizing device is miniaturized and simplified, to improve mass- productivity.
