Title: Winding method for yarn
Inventor: UCHIDA YUJI
IPC: D01H13/10
Filed: 1987-02-26
Abstract: PURPOSE:To make winding pressure for yarn in each layer sufficient and constant on a package as well as to prevent any winding looseness from occurring, by adding a state of tension to the yarn layer at the initial stage of yarn winding by a tenser in order to make up for a shortage of tension in the yarn at the time of rotation starting in the package. CONSTITUTION:At the time of starting the winding of yarn 3 on a package, a solenoid 26 of a tenser 20 is excited, attracting an arm 25, and a friction plate 22 is pressed to the friction plate 21 supported in a state of being clamped by a block 23, whereby sufficient tension is given to the yarn 3 lying between both these friction plates 21 and 22, and tension shortage at the initial stage is sufficiently compensated. And, when the package is reached to the specified speed, pressure force to the yarn 3 by these friction plates 21 and 22 is reduced, and tension of the yarn 3 is kept constant. Thus, on the package, winding pressure to the yarn at each layer becomes sufficient and constant so that winding looseness in the yarn is surely prevented from occurring.

Title: Formation of deposited film
Inventor: HOSONO HITOSHI
IPC: H01L21/027
Filed: 1989-02-23
Abstract: PURPOSE:To make small the contact area of a metal film with a substrate and to make it possible to form the metal film having a large volume on the substrate by a method wherein a resist pattern, which has a protruding part made to protrude in such a way as to block partially the lower part of a hole to penetrate from the side of the surface of the substrate to the side of the rear of the substrate, is used in the manufacturing method of a deposited film. CONSTITUTION:In the manufacturing method of a deposited film, in which a metal film 3 is deposited on a substrate 1 through a resist pattern 2p, the pattern 2p, which has a protruding part 4a made to protrude in such a way as to block partially the lower part of a hole 5 to penetrate from the side of the surface of the substrate 1 to the side of the rear of the substrate 1, is used. For example, a rectangular hole 5 is formed of a resist 2b having an overhang structure and a resist 2a having a stepped structure in such a way that the resists 2b and 2a oppose to each other and the hole 5 is provided in a state that It is shifted in the lateral direction to the substrate 1 halfway.

Title: Formation of correction curve
Inventor: TANAAMI TAKEO
IPC: G01D3/02
Filed: 1987-02-27
Abstract: PURPOSE:To obtain a continuous curve from data of many points, to make the influence of noises hard to exert, and to attain high-speed access by dividing many measurement data into several groups and performing regressive approximation, group by group. CONSTITUTION:The measurement data of all measurement points are divided into plural groups which consist of plural continuous measurement points and share measurement points at border parts. Then, the input/output relation of a measurement section to which each group belong is regressively approximated. Then, an optional output value which is set according to a constant standard is substituted in an approximate curve (approximation expression) to calculate a corresponding input value. When plural input values are calculated in this calculating process because of the presence of an overlapping approximation section, those input values are approximated regressively to find one input value. Then, polygonal line approximation connecting virtual measurement points is performed by using corresponding data of output values and input values found as mentioned above to generate a correction coefficient table. Consequently, the influence of noises is hard to exert and access is attained at a high speed.

Title: Image-transferred sheet conveying device for copying machine
Inventor: YAMAMOTO HARUO
IPC: B65H29/60
Filed: 1986-02-28
Abstract: PURPOSE:To make it possible to prevent creases, deviations in image transfer and distortion, by constituting a means for conveying a sheet to a fixing means, only with an upstream side roller pair composed of an upper roller and a downstream side lower drive roller. CONSTITUTION:An image-transferred sheet P separated from a photosensitive drum 3 by means of an one-side separating belt 4 is liable to delay in conveyance on the belt 4 laying side, without its leading end reaching a nipping point between upstream side roller pair 9, but a lower downstream side drive roller has no upper opposing roller, and therefore, it is possible to prevent a delay in conveyance. Further, since an image transferred sheet P is held in a free condition, the sheet may be conveyed to a fixing roller 6 without exerting compulsive force to the sheet P. Thus, even if the image transferred sheet is conveyed being slightly skewed, it is possible to prevent creases in the sheet, deviations in image transfer, distortion in image transfer and the like.

Title: Manufacture of semiconductor light emitting element
Inventor: OKAJIMA MASASUE
IPC: H01L21/365
Filed: 1987-03-02
Abstract: PURPOSE:To obtain desired characteristics of an element with excellent reproducibility, by a method wherein Li having the same concentration as of a p-type layer is simultaneously doped in an n-type layer too, at the time of epitaxial growth, and the Li concentration is made equal on both sides of a p-n junction to prevent Li from diffusing. CONSTITUTION:An n-type ZnSe layer 12 is grown on a Zn doped n-type ZnSe substrate 11. In this process, p-type impurity lithium (Li) is supplied together with n-type impurity, in the manner in which the concentration is made equal to that of Li in a p-type ZnSe layer 13 formed in the next process. As the concentration of Li in the n-type layer 12 and the p-type layer 13 is equal, a concentration gradient does not exist at least in the vicinity of a p-n junction, and an impurity profile in the vicinity of the p-n junction does not change at the time of epitaxial growth. Thereby, electric and luminous characteristics can be prevented from deteriorating at the time of forming the p-n junction, and the desired characteristics of an element can be obtained with excellent reproducibility.

Title: Integrated circuit
Inventor: OTA MITSUO
IPC: H01L23/50
Filed: 1990-02-28
Abstract: PURPOSE:To improve terminal density while facilitating extraction of a pattern by a method wherein a pitch between terminals on an outer array is larger than that of an inner array so that two or more of extraction patterns of the inner array terminals can pass between installation patterns of the outer array terminals. CONSTITUTION:A flat package integrated circuit 1 has two arrays of outer array terminals 2 and inner array terminals 3. A pitch between the inner array terminals 3 is reduced to the physical limit while a pitch between the outer array terminals 2 is twice the pitch between the inner array terminals 3 so that two extraction patterns of the inner array terminals can pass between outer array terminal installation patterns 4. Thus since all extraction patterns 6 from the inner array terminals 3 can be extracted outside a part, wiring is easy. In addition since the pitch between the inner array terminals 3 is re duced to the physical limit, improvement in terminal density and highly dense packaging is possible.
