IPC: G02B7/28
Filed: 1988-08-22
Abstract: PURPOSE:To facilitate the handling in varying the magnification of a zoom lens by providing an image pickup device with an automatic focusing mechanism. CONSTITUTION:The automatic focusing mechanism 6 for adjusting the focus of an optical system is provided. Namely, a CPU 19 while measuring the primary differential value of a video signal drives a master lens in an optional direction by using a motor 20. A search is made by driving the master lens 9 in the moving direction when the primary differential value of the video signal increases or in the opposite direction when not. The passage of a best- focus position is detected from a change in the direction of variation in the primary differential value of the video signal from the increasing direction to the decreasing direction and the position is stored. The master lens 9 is returned and stopped at the stored best focus position. Thus, even when the magnification of the zoom lens 8 is varied, automatic focus adjustment is performed by the automatic focusing mechanism 6, so the handling is facilitated.

Filed: 1982-11-29
Abstract: PURPOSE:To improve the detection sensitivity and durability of a device by converging magnetic flux on an oxide layer made of iron as base metal formed on the surface of a body to be measured of iron steel material corresponding to a magnetic flux passage. CONSTITUTION:The oxide layer 2 made of iron as base metal is formed at a specific part of a shaft 1 to be measured made of iron steel material so that the density decreases gradually in the depth direction of the shaft 1.
