Title: Optical recording disk
Inventor: YANAGISAWA SHUICHI
IPC: G11B7/24076
Filed: 1986-01-14
Abstract: PURPOSE:To attain stable and satisfactory recording and reproduction of information by setting the depth, the inner end width and the width of the middle part between said inner end and the surface of a substrate of a pre-group formed on the substrate at the prescribed value respectively. CONSTITUTION:A mirror surface part A, a guide address PA part B, a guide groove PG part C, and the reflected light quantity D obtained when the PG part is recorded are shown in a diagram as long as the reflection factor of the part A of an optical recording disk is set at 100. The parts B and a recording part D serve as the system control signal and the signal which records and reproduces information respectively. These signals are delivered centering on the part C. Thus the level of the part C drops when the amplitude of the part B is increased and therefore the amplitude of the part D is reduced. The depth of a groove 2 serves as a main factor to decide the level of the part C. Here the depth of the groove 2 is set at 105+ or -5nm together with the inner end width set at 0.2mum and the width of the middle part between the inner end and the surface of a substrate set at 0.45+ or -0.05mum respectively. Thus it is possible to set the difference of return light quantity between the PA and PG of the system signal and the tracking error of the PG at the optimum value respectively in relation to all recording signals.

IPC: H01C7/00
Filed: 1983-01-14
Abstract: PURPOSE:To increase productivity, improve temperature distribution and reduce cost by providing taper that makes the diameter near both ends of a roll smaller toward a tube end. CONSTITUTION:The part A of a fixing roll at which the roll touches copying paper is not tapered as before, but the part B that does not touch the paper is tapered toward the tube end. An Al2O3 insulating film 3 of about 200mum thick, a resisting film 2 of about 60mum thick, an electrode material 5 of about 200mum thick and finally a ''Teflon'' film 1 of about 30mum are melt-sprayed. By giving the taper, the tapered part having an angle theta formed by the taper obtains I/sectheta thickness compared with the thickness of the part B to make the film thickness of the part B thinner. As the electrode 5 is not projected from the tefron film 1, centerless working is possible by the surface grinding of the outer diameter of the roll, and the resistance of the part B becomes greater toward the tube end.

Title: Calculating device for surface area and volume of compound
Inventor: YUDA KOTARO
IPC: G06F7/58
Filed: 1986-01-14
Abstract: PURPOSE:To calculate the surface area or volume of a compound and an overlapping area of the surface area or volume of between atoms forming the compound, by using the spot positions obtained by using random numbers as the coordinate points of the surface or the inside of the compound. CONSTITUTION:A data base 7 is formed with the constitution attribute of a compound consisting of plural atoms and a converting means 8 converts a set of random numbers obtained from a random number generator 4 into a coordinate point between atoms extracted out of a compound having a prescribed atom constitution. A counting means 6 counts the coordinate points for each atom whose overlapping area of atoms is excluded by a deciding means 5 and calculates a ratio against all sets of generated random numbers. Then this calculated ratio is multiplied by the value serving as a prescribed unit system. N pieces of spots are produced on the surface or within the volume of an optional compound by means of random numbers. Then it is decided whether the positions of those spots should be checked and counted or not and the areas or volumes of the counted numbers are totalized. Thus the surface area or the volume of a compound is obtained uniformly. This shortens the calculating time and furthermore the area and the volume can also be calculated for an overlapping area between two different atoms.

Title: Method of observing insulating sample using scanning tunnel microscope
Inventor: YASUE TAKAO
IPC: G01B7/34
Filed: 1992-01-16
Abstract: PURPOSE:To obtain data of the minute roughness on the surface of a sample by casting charging beams such as electron beams or the like to the surface of the insulating sample and injecting the electric charges to the surface of the sample. CONSTITUTION:While a bias voltage is impressed to a probe 2, the probe 2 is moved as close as about 1nm to the surface of an insulating sample 1. At this time, the electric charges are injected to the surface of the sample 1 by using electron beams 5. Accordingly, a pseudo conductive layer is formed at the surface area of the sample 1, and the probe 2 overlaps with the electron cloud of the conductive layer at the surface of the sample 1, thereby inviting the flow of a tunnel current. A voltage is applied in the (z) direction of a piezoelectric element 3 by means of a feedback controller 4 so as to make the tunnel current constant. In this manner, an image showing the roughness of the surface of the insulating sample 1 is obtained.
