Patent JP-H02201935-A (JP)
Title: Logic of circuit provided with cippy prevention
Inventor: HARORUDO ESU KURAAFUTSU
IPC: G03F1/70
Filed: 1989-11-29
Abstract: PURPOSE: To obtain copy preventing structure, by using a library or a gate array logic cell constituted so as to be provided with an invisible 'dummy' or an 'imitation' input line. CONSTITUTION: A copy preventing structure cell is generated by using additional ion filling operation and operated by using an additional photo resist mask pattern exposing only the channel areas of electrode effect transistors 1 and 7. Additional filling permanently changes the threshold values of the two transistors 1 and 7 outside of the voltage range of signals generated at normal lines A to C. Then, a logic cell does not respond to the logic state of the signal of a line C but generates an output X based on the logic combination of the signals of the lines A and B, to correct the true value table of a NAND cell. As a result the existence of fixed error signals appear more effectively to exclude the ability of function copy.

Title: Small-sized zoom lens
Inventor: MORI NOBUYOSHI
IPC: G02B15/16
Filed: 1986-12-25
Abstract: PURPOSE:To attain a high variable power ratio while having a sufficient back focus and keeping a satisfactory performance by reducing the interval between first and second lens groups according as the power is varied from the wide angle end to the telephoto end and arranging at least two negative lenses in the first lens group. CONSTITUTION:A lens system consists of the first lens group having a positive refracting power and the second lens group having a negative refracting power in order from the object side. The first lens group includes at least two negative lenses in this two-group zoom lens system where the interval between first and second lens groups is reduced according as the focal length of the whole of the system is varied from the wide angle end to the telephoto end. Since the height of rays passing the second lens group is considerably changed by zooming, correction due to cancel of spherical aberrations of first and second groups is difficult, and it is necessary to sufficiently correct the spherical aberration of only the first lens group, and therefore, it is necessary to include two or more negative lenses there. Thus, a sufficient back focus is attained though the lens system has the two-group constitution and a large variable power ratio <=1.6, and the outside form of the second lens group is small, and aberrations are satisfactorily corrected throughout all of the variable power range.

Abstract: PURPOSE:To uniformly apply electric composite plating on a metallic material to be plated by forming a part of the inside surface of a bottomed vessel as a cathode of the metallic material, inserting an anode therein and rising a composite plating liquid along the passage between both electrodes. CONSTITUTION:The bottomed vessel 6 is formed by mounting a cap member 8 and a bottom 7 at the top and bottom of a cylinder 1 to be plated and the cylinder 1 is formed as the cathode.

Title: Method for forming seed
Inventor: AEBA TOSHIAKI
IPC: C30B25/00
Filed: 1991-10-29
Abstract: PURPOSE:To obtain a method of forming a seed such that the micro dimension of seed is obtained and an active region including the seed can be flattened and contamination on the surface of a film is little. CONSTITUTION:A polycrystalline Si film is formed in a recess made in the surface of a quartz glass substrate 1 and an SiN film 3. Then, by ion implantation to the polycrystalline Si film in a slant direction, most of region 7 of the ion-implanted polycrystalline film is formed amorphously, while a region 6 of the no ion-implanted polycrystalline film is left as a seed. Since ions are blocked in the region of the polycrystalline film near the edge of the recess, thus, a part of the polycrystalline film is not formed amorphously. As a result, the seed of the polycrystal can be left in the region formed amorphously, and the micro seed can be formed by self-alignment process without using a resist.

This material is heat-treated at 380-460 deg.C, and when an optically anisotropic phase is formed at a level of 20-70wt.%, the reaction is stopped and the optically anisotropic phase part is separated and removed. Thence, the resulting optically isotropic pitch is put to vacuum distillation at <=400 deg.C under a pressure of <=10mmHg to remove the light part along with formation of an optically anisotropic phase, which is then separated and recovered.

Abstract: PURPOSE:To always quickly complete adjustments even if various conditions are changed and to follow up changes of external factors in the case of injecting inspection signals in a servo loop and making adjustments of the characteristics of the servo loop by the response from the injection. CONSTITUTION:By a gain adjustment control circuit 13, whether an optical disk device is in a recording operation or a reproducing operation is judged; if in a reproducing operation, an instruction is given to a circuit 7 for generating inspection signals so as to make the amplitude of the inspection signals larger; and simultaneously, the average number of times for the results of a gain measurement that is performed in a gain setting circuit 12 is reduced. In the gain setting circuit 12, the gain of the servo loop is set in accordance with the average result. Thus, the amplitude of the inspection signals is increased at the time of reproduction where the control precision is not required, and the gain adjustment is performed at a high speed.
