Title: Electronic parts
Inventor: TOYODA HIROSHI
IPC: H01L21/8247
Filed: 1989-06-30
Abstract: PURPOSE:To prevent the crack generation of the ferroelectric substance film sandwiched by electrodes by forming a first ferroelectric film through an insulating layer on a silicon substrate, and providing at least one or more layers of second ferroelectric films, in the condition of being sandwiched by the electrodes, on the ferroelectric substance film. CONSTITUTION:This is made in such structure that a first ferroelectric substance film 3 is formed through an insulating layer 2 or a silicon substrate 1, and that at least one or more layers of second ferroelectric film 6 are provided, in the conditions of being caught by electrodes 5 and 7, on the ferroelectric substance film. Hereby, the difference of thermal expansion coefficient of the insulating layer 2 and the second ferroelectric substance film 6 by thermal effect can be approximated by suppressing it with the first ferroelectric film 2 formed on the insulating layer, so electric parts high in reliability can be obtained, in which the crack generation of the second ferroelectric substance film sandwiched by electrodes is prevented. Moreover, by providing an oxide layer, which has at least one kind among Mg and Zr for its main ingredient, as a ground layer for the first ferroelectric substance film, the composition changes of the first and second ferroelectric substance films are suppressed.

Filed: 1993-06-15
Abstract: PURPOSE:To achieve an efficient illumination with a compact device regardless of a large test pattern area by leading a flux of light from a light source with an optical fiber and then illuminating a test pattern with the flux of light from an emission surface. CONSTITUTION:Light from a light source lamp is gathered by a plurality of optical lenses. is led by an optical fiber 702, and is applied to a chart (test pattern) 701 with a slit which is projected by a lens to be inspected. At this time, a Y stage 703 and an X stage 705 are driven by an Y-axis DC motor 704 and an X-axis DC motor 706, respectively, thus moving the optical fiber 702 up and down and, to the left and right in reference to the surface of the chart 701. Therefore, since the light emission surface of the optical fiber 702 can move within a surface in parallel with the surface of the chart 701, the loss of quantity of light can be reduced and light can be applied to the surface of the chart 701 uniformly and efficiently without increasing the size of the entire device even if the area of the chart 701 can be increased.

Title: Fluid acting upon magnetic field
Inventor: EMIRU MEIYAA SHIYUTAAKUMAN
IPC: H01F1/44
Filed: 1990-06-27
Abstract: PURPOSE: To provide excellent lubrication by composing a fluid composition of a vehicle, e.g. mineral oil, silicon oil or CONOCOLVT oil, insulating reductive carbonyl iron and a dispersant, preferably entangled carbon fiber particles. CONSTITUTION: Carbonyl iron is produced by decomposing pentacarbonyl iron Fe(CO)5 . Spherical nonreductive particles, referred to onion skin tissue, are obtained from that process because trace carbon deposit is present in alternative layer. Content of carbon is about 18%. The nonreductive particles are reduced or decarbonized by exposing the particles to hydrogen atmosphere and then compressing the particles. Onion skin tissue is destroyed through the process to bring about a structure where fine iron particles are arranged randomly. Carbon content of the particle is about 0.075%. For example, the reductive particle is applied with an insulating coating in order to prevent inter-particle contact. The particle is physically soft, compressive and has spherical shape.
