Title: Stereoscopic scanning electron microscope
Inventor: KURODA KATSUHIRO
IPC: H01J37/28
Filed: 1983-03-18
Abstract: PURPOSE:To provide a stereoscopic scanning electron microscope enabling high resolution stereoscopic observation on a real-time basis, by forming such an electric field that will decelerate the electron beam in the vicinity of the specimen surface. CONSTITUTION:The electron beam coming from the electron gun 14 is converted at the objective point 1 having energy corresponding to a voltage V1. The beam then is caused to form an image at the point 15 beyond the specimen 2 by the action of the lens 3. Meanwhile, the specimen 2 is applied with a voltage with reference to the electron gun 14. If V2<V1, a decelerating electric field is built up between the lens 3 and the specimen 2 to form an electrostatic lens there, whereby the image formation point 15 by the action of the lens 3 is shifted to the image formation point 1b on the specimen. If in the meantime the deflectors 4, 5 are adapted to act so that the electron beam 16 seems to be coming from the objective point 1, then the beam would be incident to the image forming point 1b at a stereoscopic angle beta by the action of both the lens 3 and the electrostatic lens over the specimen surface. The stereoscopic angle beta is larger than the stereoscipic angle beta' in the case without the electrostatic lens, and a stereoscopic image with high resolution can thus be obtained.

Title: Focus setting device for optical disk device
Inventor: OZAWA YASUYUKI
IPC: G11B7/085
Filed: 1986-02-28
Abstract: PURPOSE:To attain the stable focus control by exerting the variation in the horizontal direction to a recording medium prior to the drive for focus setting. CONSTITUTION:Prior to start the focus control, a track vibration signal (e) is outputted from tracking servo circuit, amplified by a power amplifier 12 to drive a tracking coil 13 thereby causing the displacement (f) of a lens in the track direction. Although a rapid jump similar to a conventional jump in the focus direction at the impression of the signal (e) is caused in the track direction, there is no possibility of collision with a disk in the track direction. Since the lens is vibrated in the track direction by the residual vibration at the start in the focus direction, no rapid jump is caused and the vibration in the track direction at the focus setting operation is not a problem so long as the amplitude is not especially large. Thus, the stable focus setting circuit having no possibility of the collision between the lens and the disk is obtained.
