Abstract: PROBLEM TO BE SOLVED: To impart forgery/counterfeit preventive effects by a copying machine, to securities, etc., by a method wherein in a curved image line of a part where a latent image is applied, at a part where each pair of image lines cross with each other, the image lines of either one pair of respective pairs of the image lines, are deleted on the inside of the image lines of the other pair of the image lines. SOLUTION: In image lines 13 at a part where a latent image is applied, i.e., in the image lines which become a pair with two or more lines, to either one pair of the image lines 13 of respective pairs of the image lines 13, when the other pair of the image lines 13 is located at the internal range of the other pair of the image lines 13, at a cross point 10' where latent image curves 14 of respective pairs of the image lines 13 cross with each other, only for that area, the inside of the other pair of the image lines 13 is deleted. By this method, even if the part where the image lines which become pairs with two or more lines cross with each other in the latent image applied area, seems to exist, actually, the cross of the image lines with each other does not exist in the area where the latent image is applied.  Therefore, the density of the image lines at the cross part can be prevented from becoming higher.

Abstract: PURPOSE:To reduce a cost through the common use of a part by a method wherein a rotation angle range in which a rotary compressor of a next stage performs a compression process is made smaller than that of a rotary compressor of a preceding stage. CONSTITUTION:In a rotary compression mechanism 4 of a next stage, a rolling piston 19 loosely engaged with a crank pin 6b formed such that its phase is displaced by 180 deg. to a crank pin 6a is contained in a cylinder chamber 22. The lower end of a cylinder block 17 is notched throughout a range extending in a 180 deg. arc from a position near a blade 20 along the rotation direction of the rolling piston 19 to form a notch groove 30, which is communicated with a lower muffler chamber 27 through a gas passage 31. Since, in the rotary mechanism 4 of a next stage, a compression stroke is not started before the rolling piston 19 is rotated approximately 180 deg. based on the phase of the blade 20 to reach the terminal end of the notch groove 30, displacement VH of the rotary compression mechanism 4 of the next stage is made smaller than approximate a half of displacement VL of a rotary compressor of a preceding stage.

Abstract: PROBLEM TO BE SOLVED: To obtain a high capacity low voltage semiconductor memory by selecting the material of floating gate electrode and channel region such that the Fermi level of a floating gate electrode is located in the band gap of the channel region under a state where no voltage is applied externally. SOLUTION: A floating gate electrode 6 of 10 nm thick is arranged on the surface of a tunnel insulating film 5. The floating gate electrode 6 is formed of a high melting point metal, e.g. TiN, selected such that the Fermi level Ef of a floating gate is located between the conductive band lower end Ec and the valence band upper end Ev of a channel region 4, i.e., in the band gap. Consequently, the surface layer in the channel region 4 is depleted when no voltage is applied to a control gate electrode 8. When a voltage is applied to the control gate electrode 8, carriers tunnel through the tunnel insulating film 5 directly and thereby writing and erasure can be effected at a relatively low voltage.
