Title: Method and equipment for estimating impurity distribution, and method and equipment for manufacturing semiconductor
Inventor: MATSUZAWA KAZUYA
IPC: H01L21/336
Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To realize a MOS transistor with desired electric characteristics changing manufacturing condition, by comparing the simulation results of the electric characteristics of such device structures as the shape of the element and its impurity distribution with their measured values, and by estimating the impurity distributions of the MOS transistor. SOLUTION: Inputting a lot to the manufacturing process of a semiconductor (S21), and forming an LSI (S22), both the simulation results of Isub (substrate current), Id (drain current) and Vd (drain voltage) of a MOS transistor and the measured value of its Vdsat (drain saturation voltage) are used to measure its Isub /Id -1/(Vd -Vdsat ) characteristic (S23). Then, deciding the measured result by comparing it with its set value (S24), the manufacturing process is ended when deciding the absence of abnormality in the measured result and it is advanced to a step 25 when deciding the presence of abnormality in the measured result to estimate the channel impurity distributions in the vicinities of the drain and source of the MOS transistor by an equipment for estimating impurity distributions. Therefore, altering the manufacturing conditions of an equipment for manufacturing semiconductors so as to make the abnormality problem avoidable (S26), the manufacturing process is repeated until deciding the absence of abnormality in the measured result to make the abnormality problem avoidable.

Title: Automatic paper selecting and supplying apparatus
Inventor: NISHITSUJI HIDEFUMI
IPC: B65H3/44
Filed: 1983-09-26
Abstract: PURPOSE:To prohibit printing of a blank having different quality to prevent confusion in an automatic paper selecting and supplying apparatus by disabling a limitless function when the paper quality differs even if the blank having same size and direction appears in the absence of paper. CONSTITUTION:A control section consists of CPU (central control unit) 1, ROM (read only memory) 2, RAM (random access memory) 3, I/O element (input/output element) 4, etc. During copying, the presence of paper being supplied on a specified paper supply bed is normally checked. If the paper on said bed disappears before set number of papers is supplied, whether or not any paper supply bed is there which receives copy papers having the same size and direction as those dissppearing from the other beds at that time is searched. If there is no such bed, a lamp for displaying the absence of paper is lit to stop the copying operation. If there is such bed, the display on the specified bed is shifted to such bed to continue the paper supply, provided the paper is processed in the same way as the case of the absence of the bed mounting the same size and direction paper when the paper quality differs even if the paper of same size and direction is present.

Abstract: PURPOSE:To suppress the variation in the impedance of a transformer when a tap position is switched by dividing an exciting winding into two segments, and so winding each coil on side legs as to hold a tap winding between the segments. CONSTITUTION:An exciting winding is divided into first and second exciting winding segments 16a and 16b, the segment 16a is wound inside a side leg 12, and a tap winding 17 is wound on the outside of the segment 16a.

Title: Individual identification device
Inventor: OKANO KENJI
IPC: G06K9/68
Filed: 1997-06-18
Abstract: PROBLEM TO BE SOLVED: To provide an individual identification device capable of executing identification even when the picture quality to be acquired is not good. SOLUTION: An identification dictionary 1 stores feature data of an object to be identified and additional information showing intrinsic features peculiar to the object to be identified. When an individual identification cannot be executed by an individual identification means 2, an operation instruction is given to an additional information input means 5 and a reidenitification means 6. At every time a piece of additional information is added to the additional information input means 5, the reidentification means 6 narrows down dictionary data in the identification dictionary 1 which is compared by this additional information and the dictionary data of the highest matching degree is outputted to an identification result judgment means 4.  The identification result judgment means 4 compares this dictionary data with a threshold value which underestimates a value to be identified and when the individual identification can be executed, this is outputted as the final identification result; when the individual identification cannot be executed, an instruction is given to the additional information input mean 5 and the reidentification means 6 and the above- mentioned processing is repeated.

Title: Magneto-optical printing method
Inventor: UEHARA MASAMITSU
IPC: B41J2/42
Filed: 1986-07-29
Abstract: PURPOSE:To facilitate degaussing a magneto-optical layer and inverting the polarity without generating a static electricity even in case of the optical input having a low intensity of energy by adjacently providing the magneto-optical layer, to which a toner is selectively stuck, and an optical switching layer which can control the current only in a light-projected part which locally heats the magneto-optical layer and performing optical write while applying an electric bias. CONSTITUTION:A magnetic layer 6 formed on the surface of a magneto-optical drum is uniformly magnetized in the same magnetization direction of arrows 26 as lines 25 of magnetic force. If the electric bias is preliminarily applied to the magneto-optical layer 6 and an optical switching layer 5 through a transparent electrode 7 and a metallic electrode 4 and a bias magnetic field in applied by a magnetic bias coil 19 and a laser beam pulse 12 is locally projected in this state, a light-projected part 28 of the optical switching layer 5 is turned on, and a current 27 concentratedly flows to a light-projected part 29 of the magnetic layer 6 through the transparent electrode 7, and the electric resistance of the light projected part 28 is lower than that of the light projected part 29 of the magnetic layer 6 so that it can be ignored. A leak magnetic field 32 to the surface of the drum is strong near a boundary 31 of a magnetization-inverted part in the magnetic layer6 after cooling, and a magnetic toner 33 is selectively stuck to a part near the boundary 31. Thus, a small-sized light source is used to quickly perform printing with low intensity of light.
