Title: Method of producing polycrystal garnet for micro wave
Inventor: KANAI KUNIO
IPC: H01F1/34
Filed: 1978-07-31
Abstract: PURPOSE: To effect the reduction in void and the increase of high density level by using denaturated alcohol in place of pure water as dispersion solvent in the mixing and grinding processes of various raw materials at the time of producing the polycrystal garnet, removing the alcohol after the completion of processes and then calcinating it.  
     CONSTITUTION: Polycrystal garnet with composition formula of (Y 2.3  Ga 0.7 ) (Fe 1.45  In 0.55 ) (Fe 2.65  V 0.35 ) O 12  is produced through the composition of (Y 3-2x  G 2x)   ( F e2-y  In y ) (Fe 3-x  V x ) O 12 . In order to obtain that composition, various raw materials such as Y 2 O 3 , CaCO 3 , Fe 2 O 3 , In 2 O 3  and V 2 O 5  are weighed and then mixed and ground in the steel ball mill. In this method, denaturated alcohol or ethanol is used as despersion solvent in the processes of mixing and grinding. This leads to the reduction in void and ΔH value due to no occurrence of heterophase and thus decrease the device loss rate significantly.

Abstract: PURPOSE:To provide the beam splitter which equalizes division ratios of reflected light and transmitted light and is widened in the degree of freedom in optical designing by laminating and combining 9 layers of layers having specific optical constants at specific optical thicknesses. CONSTITUTION:This beam splitter is constituted by using a prism consisting of optical glass having 1.932 refractive index as an incident medium 11 and a prism consisting of optical glass (BKT) having 1.518 refractive index as a substrate 12. Nine layers of the layers consisting of the materials shown by a Table (1) are laminated on the slope of the prism substrate 12 having 90 deg. vertex and another one piece of the prism incident medium 11 of exactly the same size is joined thereto by an adhesive layer 10 (n=about 1.50, 7 to 8mum geometrical thickness), such as hard rock, by which the cubic beam splitter is produced. A part of the incident light on such beam splitter from an arrow (a) is reflected toward an arrow (b) and the balance successively transmits the 9th layer to the first layer and further transmits the substrate 12.

IPC: G11B5/133
Filed: 1989-04-12
Abstract: PURPOSE:To improve reliability and to increase a yield at the time of manufacturing by providing recessed level differences on the both edge surfaces of a magnetic core powder press compact. CONSTITUTION:An Mn-Zn ferritic powder press compact having a high relative magnetic permeability characteristic is sintered to mold the compact at a width 4mm. Step parts (e) and (g) at a length 5mm and a depth 0.3mm are formed on the both edge surfaces of the compact. Next the compact is roughly ground by 0.3 to 0.4mm/path by a creep field grinder, and continuously finely ground by 0.2 to 0.1mm/path by a longitudinal shaft grinder, and the head core ferritic plate at the width 3mm (the width is A and indicated by a two dot chain line) is obtained. Thus by grinding the both surfaces by 0.5mm respectively, a notch or a crack generated on the edge surface of the ferritic plate at the time of grinding can be prevented owing to the effect of the step parts (e) and (f), and the highly reliable compact can be obtained at the high yield.
