Inventor: WATANABE TOSHIHARU
IPC: H02K1/17
Filed: 1980-12-24
Abstract: PURPOSE:To improve the rectifying operation and the output performance of a DC machine by installing a magnetic suppressing piece of a ferromagnetic unit at the end and an armature facing via a small air gap with the piece in the space between adjacent poles of permanent field magnet and magnetic focusing pole piece. CONSTITUTION:A magnetic suppressing piece 36 of a ferromagnetic unit is projected from a yoke 10 in the space 34 between adjacent poles formed of permanent field magnet 12 of ferrite magnet and focusing pole piece 14. The piece 36 is bent outwardly at the predetermined position, and is approached in parallel with the side 28 of the piece 14. A support 42 of nonmagnetic material is interposed between the bent part 40 of the piece 36 and the side 28 of the piece 14, thereby supporting fixedly the bent part. Accordingly, the magnetic gradient along the outer periphery of the armature between the ends A and B of the piece 36 is remarkably reduced, thereby largely reducing the leakage magnetic fluxes 30, 32 flowing into the teeth 22 of the armature. Thus, the rectifying operation and the output performance can be improved.

Title: Plastic sheet and production thereof
Inventor: TACHIBANA KAZUHIRO
IPC: B29D11/00
Filed: 1988-07-21
Abstract: PURPOSE:To obviate the exfoliation of a UV or EB curing type resin layer even if the size is increased and to obtain sufficient strength by providing a primer layer on a substrate, forming a surface layer consisting of the UV or EB curing type resin thereon and forming the shape of a Fresnel lens on the surface layer. CONSTITUTION:A metallic mold 4 is previously coated with the oligomer or monomer of an urethane acrylate as the UV or EB curing type resin to form the resin layer (surface layer 3a) of the uncured state. A sheet previously formed with a primer layer 2 on a substrate 1 is then placed on the resin layer to form the uncured surface layer 3a. The surface is then irradiated with UV so as to transmit the substrate 1 and the primer layer 2 to cure the resin layer (surface layer 3a), by which the surface layer 3b is formed. This layer is stripped from the material mold 4 to form a plastic sheet and is then subjected to thermal working. The adhesive strength of the surface layer is enhanced in this way and the stable Fresnel lens having the high mechanical strength is obtd.

Title: Method for forming resist coating
Inventor: ARAIHARA SATOSHI
IPC: C23F1/00
Filed: 1983-09-30
Abstract: PURPOSE:To eliminate the contamination due to rebound and blow-up of resist by accompanying the formation of a film, which is performed by high-speed spin of a spin head after setting a substrate to be treated on the spin head and dropping a resist liquid, with a rise of the spin head. CONSTITUTION:Resist is dripped on a substrate 1 fixed to a spin head 2 by adsorption. When a motor 4 starts, an air cylinder 7 synchronizes with that and operates to diffuse the resist over the substrate 1 with scattering the surplus from the periphery of the substrate 1. Most of the scattered resist bumps against a spin cup 5 and rebounds. Some of that is blown up by a diffused air stream generated by spin of the substrate 1 and the spin head 2. As the substrate 1 has been raised, it is not deposited on the substrate 1. Also, as the substrate 1 and the spin head 2 rise to reach the positions substrae 1' and spin head 2', a space between these and the spin cup 5' becomes narrower. Consequently, a current speed by adsorption of an exhaust duct 6 increases and the diffused air stream is pulled downward strongly.

IPC: G02B13/18
Filed: 1987-07-21
Abstract: PURPOSE:To compensate the spherical aberration, sine condition, astigmatism, and comatic aberration of a single lens greatly and excellently over a wide visual field by forming both convex surfaces of the single lens aspherically, and employing a term of high order of the height from the optical axis up to specific power as their aspherical surface coefficients. CONSTITUTION:A biconvex lens form a reduced image of a body at an infinite distance and an equation I holds for the distance (x) of a point on the aspherical surface from the contact plane at the lens surface peak point, the height (h) from the optical axis, the curvature C of the aspherical surface peak point, the constant (k) of ellipticity, and the coefficient A2i of the aspherical surfaces. Namely, the coefficient of the aspherical surfaces contains the term of high order of the height (h) from the optical axis up to 18th power, and consequently excellent aberrations are obtained. An inequality II shows the range of the refracting power of the object-side surface of the single lens, an inequality III shows a flat image plane having no astigmatism, and an inequality IV shows a range where a decrease in performance due to the parallel eccentricity of the both lens surfaces can be precluded under said conditions, where (f) is the focal length of the single lens surface, r1 the radius of peak curvature of the object-side lens surface, (d) the center thickness of the single lens, and (n) the refractive index of the material of the single lens.

Filed: 1983-09-29
Abstract: PURPOSE:To eliminate the need for adjustment at mode switching by increasing the contrast ratio between a display signal and a television video image signal when a superimposing display mode is detected in a receiver having the superimposing display mode.

Abstract: PURPOSE:To eliminate the influence of a background and disturbing ray, by computing the difference of intensity of light of an analysis light source and a spectrum of a central wavelength lambdao of analysis ray of light passing through a light absorption part. CONSTITUTION:Light emitted from an analysis light source 1 is divided into two pieces of light flux by a sector mirror M1 and straight-advanced light is reflected by a sector mirror M2 and then, is made incident to a spectroscope 3. Reflected light is passed through a light absorption part 2 and is advanced to the mirror 2 straight and is made incident to the spectroscope 3. The light of a central wavelength lambdao is emitted from the spectroscope 3 and is made incident to a photodetector 4.
