Title: Scanning type electron microscope
Inventor: ISHIKAWA HISASHI
IPC: H01J37/28
Filed: 1984-11-30
Abstract: PURPOSE:To heighten detection efficiency of the secondary electrons and reflection electrons without increasing ground electrostatic capacity by making a collection electrode to be of the smallest shape surrounding a sample while electrically dividing said electrode at least into two parts. CONSTITUTION:A sample is surrounded by a cylinder having a radius corresponding to the size of the sample 7 and an incident hole 22 of an electron beam to the sample 7 on its top part while being divided into two parts, right and left, by an insulator 23 for being made into a collection electrode. The sample shall be heated to high temperature while being provided with a control grid 21 as occasion demands for sorting thermal electrons from the secondary electrons or the reflection electrons while adding slight negative potential, for instance, about -1V by using variable power supply 40 in order to control thermal electrons. A signal from the collection electrode is amplified by an amplifier 30 for getting a picture signal. The electrode can be made to have the minimum area for reducing the ground free capacity while being able to take a large solid angle, at which the collection electron is seen from the sample, so as to be able to collect almost all reflection electrons and secondary electrons.

Title: Convergence correction circuit
Inventor: AOKI KYOSUKE
IPC: H01J29/76
Filed: 1997-09-17
Abstract: PROBLEM TO BE SOLVED: To correct an X axis longitudinal mis-convergence independently right and left in a horizontal direction of the seven. SOLUTION: A bias magnetic field is given to coils L1, L2 in the same direction and a bias magnetic field is given to coils L7, L8 in an opposite direction to the direction given to coils L1, L2. Inductances of coils L3, L4 and coils L5, L6 are respectively changed differentially. A correction coil L9 is connected so that the coils L1-L9 configure a bridge circuit 1 as a whole. The coil L9 is divided into two and they are connected to both sides of an electron gun. The bridge 1 becomes unbalanced by changing differentially the inductance of the coils L3, L4 or the coils L5, L6 and a current flows to the coil L9. An X axis longitudinal mis-convergence is corrected independently on the left/right sides of the screen by respectively adjusting the coils L3, L4 and the coils L5, L6.

Title: Optical memory medium including multiplex data level consisting of co/pt magneto-optical recording medium
Inventor: YUANNSHIEN TEIAN
IPC: G11B7/254
Filed: 1996-08-19
Abstract: PROBLEM TO BE SOLVED: To enlarge coercivity and to improve the squareness characteristic of a Kerr hysteresis loop by providing a memory medium with multiple data memory levels and the memory levels consisting of transparent dielectric seed layers and a partial transparent memory layer of multilayered structure including Co/Pt alternate layers thereon. SOLUTION: This optical data memory medium includes the three data levels.

The transmittance of light for the first data level 1 needs to be max. (at least >=40%). As a result, the laser beam arranged on one side of the disk structure penetrates the first layer and the subsequent layers. Recording or reading out is thus executed without using the excessive laser power. The desirable thickness in the case of the high-performance Co/Pt superlattice disk is >=15nm.

Title: Optical information recording and reproducing system
Inventor: OOTA TAKEO
IPC: G11B7/126
Filed: 1984-11-29
Abstract: PURPOSE:To obtain equal output signals at all track positions by rotating a recording and a reproducing disk at a constant angular speed and equalizing recording signals in dot length at an inner and an outer peripheral part. CONSTITUTION:When a data signal 1 is inputted, the address signal 2 of a recording track is detected and a frequency converter 3 selects the frequency of the track position corresponding to the signal 2 among f1-fn to convert a carrier signal frequency. Modulation is imposed upon a semiconductor laser 4 by using the converted signal to generate laser pulse light 5, which illuminates a rotary disk. Consequently, conversion for increasing the carrier signal frequency is performed at outer peripheral tracks for the innermost periphery to reduce the with of the laser pulses, thereby equalizing the recording dot length of the innermost periphery to that of the outermost periphery. The peak power of the laser light at the outer periphery is set high corresponding to track positions to equalize thermal variation of recording dots.

Title: Polishing head and polishing device
Inventor: TAKIMOTO MASAFUMI
IPC: B24B37/00
Filed: 1991-09-30
Abstract: PURPOSE:To make a polishing head match the continuous change of polish- machining force necessary for the all curvatures of the surface shape of a workpiece. CONSTITUTION:The body 51 of a polishing head 50 is fixed at a prescribed position on a polishing head attaching plate 48. A porous member 55 has a bore larger than the outside diameter of a cylindrical spindle 52, and noncontactingly supports the spindle 52 by an air bearing into which a supplied air P3 flows through its clearance. But there is no restriction in a vertical direction, and the spindle 52 is therefore movable in a direction denoted by an arrow A. If a difference between the pressures of the air P1, P2 supplied to each of two air chambers 53a, 53b occurs, force is thereby generated in the vertical direction of the spindle 52. On the other hand, an elastic spherical tool 65 is attached to a rotary shaft 64, which is supported by plural number of the air bearings.

Title: Multiaxial force sensor
Inventor: YAMAGAMI GENSAKU
IPC: G01L5/16
Filed: 1996-09-03
Abstract: PROBLEM TO BE SOLVED: To regulate the output matching of axial force and moment with a relatively inexpensive structure by mutually differing the spring constant between an axial force detecting distortion generating part and a moment detecting distortion generating part. SOLUTION: The spring constant is mutually different between an axial force detecting distortion generating part and a moment detecting distortion generating part, whereby the mechanical load-distortion characteristic for each distortion generating part is regulated to mutually balance the output dynamic ranges of each directional distortion. For example, the sectional areas of the part for sticking axial force detecting strain gauges 6a-6d and the part of sticking moment detecting strain gauges 7a-7d in one beam 4 are mutually differed, or a slit 5 is provided on the base of the beam 4 to form the axial force detecting strain generating part. Namely, both X, Y beams 3, 4 are made more slender in the center parts than in both end parts. The base parts to a frame part 2 of the beams 3, 4 are thinned by the slits 5 in order to allow the axial displacement.

Filed: 1989-09-29
Abstract: PURPOSE: To reduce post shooting distortion and to improve the characteristics of convergency and stability of an equalizer by forming a sum total signal from a product signal and a sum signal generated by multiplication by using an adder. CONSTITUTION: A preshooting equalizer is constituted as a transversal filter and a digital signal x(n+2) appears on the input side of the equalizer simultaneously with digital signals x(n+1), x(n) appearing on the output side of a delay element T. These digital signal are supplied to multipliers M1 to M3. The multiplier M1 multiplies the signal x(n) by a main coefficient C0 and the multipliers M2, M3 respectively multiply signals x(n+1), x(n+2) by respective sub-coefficients C-1 , C-2 . The output sides of these multipliers M1 to M3 are connected to the input side of an adder ADD1 and a distortion removed digital signal y(n+2) is sent from the output side of the adder ADD1. Thus post shooting distortion is additionally reduced by the signals supplied to the adder ADD1.
