Title: Selective doping method
Inventor: NAKAO MASAO
IPC: H01L21/203
Filed: 1987-03-02
Abstract: PURPOSE:To enable doped semiconductor thin wires to be prepared which can be expected of the quantum effect by providing a spatial intensity distribution to a soft X ray of a specific wavelength which is used in the photo excited doping method. CONSTITUTION:A high-resistance gallium arsenide substrate 7 is mounted on a sample holder 1, a gallium molecular beam and an arsenic molecular beam are applied from a molecular beam cell 4(5) to perform molecular beam epitaxial growth and simultaneously, a silane gas is introduced onto the substrate 7 from a gas cell 6, and further, a soft X ray having a wavelength of several tens to several hundreds of Angstrom  which is light by synchrotron radiation is made to be incident upon the substrate 7. The soft X ray is modulated by an X-ray interferometer to one having a spatial intensity distribution consisting of a pattern of repeated strong and weak intensities and will reach the surface of the substrate 7. At this time, silane is decomposed and doped only in the places where the soft X ray intensity is strong, forming N-type thin wires having spacings on the order of the wavelength used. On the other hand, the other place becomes a non-dope layer 9 into which no dopant has been introduced.

Filed: 1990-02-28
Abstract: PURPOSE:To reproduce an achromatic color without staining and a chromatic color with high lightness by providing plurally divided addresses in one picture element and developing the electrostatic latent image of each color in order of address. CONSTITUTION:The plurally divided addresses 1-7 are provided in one picture element of a photosensitive drum.

After all the addresses 1-7 are filled, two latent images are formed in the identical address 2 for the first time to reproduce an image. As to color image processing at an initialization stage, the respective picture elements of a color original are converted into the output signals of respective colors of red(R), green(G) and blue(B) by a color scanner, and the respective output signals are compared with each other to decide whether each picture element is achromatic or chromatic. Thus, the achromatic color without turbidity or staining and the chromatic color with high lightness are reproduced.

SOLUTION: At the manufacturing of a wire-wound magnetic thin-film inductor 22, an inductor 21 is first manufactured by forming magnetic films 3 on both surfaces of a glass substrate 2 and forming a winding 4 around the substrate 2 and films 3, for suppressing the height of the inductor 21 by taking the size of the inductor 22 into consideration. At the forming of the films 3 on both surfaces of the substrate 2, in addition, magnetic core sections are formed as divided thin magnetic core films 5 and 5 on both surfaces by further dividing the thin films 3 into two rows for suppressing the magnetic domain which is optimum for obtaining height magnetic permeability and overcurrents. Then the inductor 22 is manufactured, by forming appropriate spaces among the turns of the winding 4 with the use of the magnetic core sections thus formed.  The Q-value of the inductor 22 may reach a value of >=50 in the vicinity of 40 MHz. Therefore, a wire-wound magnetic thin-film inductor having small size, high heat resistance, and stable temperature characteristic can be manufactured.

Title: Neutral position setting method of steering angle sensor for vehicle
Inventor: OSHITA SAIICHIRO
IPC: B60G17/00
Filed: 1989-03-01
Abstract: PURPOSE:To dispense with any neutral position setting operation at time of a neutral position memory blackout by constituting a microcomputer to set a neutral position mark detecting position as a neutral position when a car speed is more than the setting value and an operating range continues such a state as within the setting angle range as long as more than the specified time. CONSTITUTION:When such a state as satisfying the following conditions that car speed is more than the setting value, steering force is less than the setting value and a steering range is less than the setting value has continued as long as the specified time, it is so judged that a vehicle is in an almost rectilinear state, and thereby a detecting position of a neutral position mark 3 detected within the set steering range should be set to a neutral position A. With the setting logic of the neutral position A such like integrated into a microcomputer, when memory contents are lost as after battery removal, the rectilinear state of the vehicle is estimated by only judgment of conditions during travel without doing any special operation, so that resetting of the neutral position A can be performed.

CONSTITUTION:To obtain even winding hardness at diffecernt parts of a package, the number of winds must be raised, and the number exceeding three both at the inner and outer layers of the package should provide a substantially equal winding hardness at the tab parts and the center of package, wherein a difference of less than 5 deg. enables over 75 deg., preferably in a range between 75 deg. and 85 deg.. To prevent entanglement of the process yarn, each multi-filament must be focusing, at least having an intersection of one meter per five pieces. Further it is required that the traverse angles at the inner and outer layers are substantially equal, being below 13 deg., and exceeding 13 deg. will make the number of winds too small to caeuse entanglement of the yarn in the underlayer, and the overlayer yarn will be entangled with the underlayer yarn, so that unwinding yarn cut is easily generated.
