Title: Photographic lens system for stabilizing image
Inventor: HORIUCHI AKINAGA
IPC: G02B5/06
Filed: 1990-05-16
Abstract: PURPOSE:To miniaturize a device and to prevent picture quality from being degraded by providing the device with a variable apex angle prism unit satisfying a specific condition. CONSTITUTION:The variable apex angle prism unit V whose apex angle is to be changed in order to refract an optical axis is arranged in a lens system for changing at least one lens interval out of plural lens groups f1 to f4 to change the whole focal distance. Assuming that synthetic power from a 1st face on the object side up to a prescribed face immediately before the unit V is Fa and the focal distance of the whole system at the telephoto end is Ft, the unit V is arranged on a position satisfying the condition of ¦Fa¦<10Ft. The condition is obtained by finding out power arrangement suppressing the generation of a ghost or flare which may practically generate a trouble on an image face I from the optical analysis result of an optical system including various zoom lenses. Consequently, it is unnecessary to expand the unit V and the picture quality can be prevented from being degraded especially due to a ghost or flare.

Title: Focussing device for electron microscope
Inventor: TANINAKA TAKASHI
IPC: H01J37/26
Filed: 1980-09-17
Abstract: PURPOSE:To easily obtain a desired insufficient or excessive focal point image and prevent dirt of an objective diaphragm by deflecting an electron beam by means of a deflection coil which is provided between an objective lens and an observed image surface and performing focussing using the insufficient or excessive focal point image. CONSTITUTION:When an electron beam emitted from the observation point 4 on a sample surface 1 is focussed on an image surface 15 near an image surface 9 that is separated from an obserbed image surface 3 by length DELTAfi, the passages of electron beams 7' and 8' are obtained from irradiated electron beams 7 and 8 by alternately varying an irradiated electron beam 6 passing on the axis of a lens 2 by an angle alpha. Then electron beams 7'' and 8'' are obtained by exciting a deflection coil 12 which is provided between the lens 2 and the observed image surface 3 and deflecting the electron beams 7' and 8' on an axis by an angl alpha and the angle beta which is assigned depending upon the insufficient focal point. A focussing image surface is moved from 15 to 9 and made coincide at the point 5 on the observed image surface 3. When samples are observed at the insufficient or excessive focal point, focussing is facilitated. The angle alpha can be reduced and dirt of an objective diaphragm be preveted.

Title: Optical disk device
Inventor: KUMON YUJI
IPC: G11B7/00
Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To enable discriminating of the class of a disk in the midst of the starting up of an optical disk device without reproducing a signal by extracting a wobbling component from the optical disk and discriminating two kinds of optical disks in accordance with results measured by a measurement means for measuring the cycle of wobbles. SOLUTION: A wobble signal extracting circuit 207 restricts a band by a band-pass filter in order to pass a prescribed band to eliminate components other than the band. After the circuit 207 has extracted this wobble component, it binarizes the component and the cycle of the wobbles is measured with a counter by eliminating the area of addresses from the wobble component with a reference clock, for example, the clock of 29.2 mHz by a wobble cycle measuring means 208. At this time, when an optical disk 201 is a DVD 2.6 GB, the count value of the counter becomes about 186 counts and when the disk is a DVD 4.7 GB, the count value becomes about 124 counts. Then, a disk discriminating means 209 discriminates the class of the disk by these count values.

Title: Dc magnetic field inversion type erasing head
Inventor: FUJITA JUJI
IPC: G11B5/23
Filed: 1980-09-16
Abstract: PURPOSE:To obtain a standard erasing head having a low level of distortion factor with the reduced variance of the leaked magnetic flux toward the width direction of a tape, by stacking alternately a core having nearly a T-shaped side face and a core having a frame-shaped side face and then winding a coil symmetrically around these cores. CONSTITUTION:The 1st core plate 1 having a frame-shaped side face and the 2nd core plate 2 having nearly a T-shaped side face are stacked alternately. In this case, a vertical side 2a of the plate 2 is exposed between the opposite sides 1a of the plate 1, and at the same time a horizontal side 2b of the plate 2 overlaps a horizontal side 1b of the plate 1. Thus a gap 3 is formed between the plates 1 and 2. Then a coil 4 is wound symmetrically around the side 2a to obtain two loops as shown by the arrow marks. If a leaked magnetic flux of 1/2l is secured to the gap height (l), the entire width of a tape can be effectively secured for the leaked magnetic flux. The distortion factor can be stabilized at a low level of 2%.
