Title: Production of single crystal film
Inventor: IWAMATSU SEIICHI
IPC: H01L21/208
Filed: 1988-04-22
Abstract: PURPOSE:To enable the production of a single crystal film having little crystal defects at a high speed, by forming a polycrystalline or amorphous Si film on a single crystal growth seed or insulation film of the edge of a single crystal Si substrate or other regions and converting the Si film to single crystal with an energy beam. CONSTITUTION:A specimen is placed on a carbon heater 1 heated at a specific temperature by electric current. The specimen is composed of a single crystal Si substrate 2 coated its major part with an insulation film such as SiO2 film, Si3N4 film or their double-layer structure film and a part of the insulation film 3 is etched to open a window through which the substrate 2 is exposed at the edge part. The exposed part of the substrate is used as a growing seed part 4 for single crystal Si and the surface of the part is made to form nearly a plane with the surface of the insulation film 3. A polycrystalline Si film 5 is formed on these surfaces by CVD process, the part of the growing seed 4 connected with the substrate 2 contacting with the film 5 is linearly irradiated with energy beam 6 such as electron ray in the direction of X and the film is transferred in the direction Y under partial melting. The part of the polycrystalline Si converted to single crystal during the cooling process grows continuously in the direction Y to form a single crystal Si film having nearly flat surface over the whole surface.

Title: Slide face constituting body
Inventor: DOUSAKA KENJI
IPC: F02F1/00
Filed: 1995-03-31
Abstract: PURPOSE: To provide a slide face constituting body capable of reducing a friction loss even when the viscosity of lubricant is high. CONSTITUTION: This slide face constituting body is formed with an aggregate of metallic crystals. The area ratio of the rounded pyramidal metallic crystal 6 on the slide face is controlled to 40 to 100%. Each ridgeline 7 on the crystal 6 is projectingly arched, and each region 8 corresponding to a slope between the adjacent ridgelines 7 consists of two strip regions 9 each as a slope on one side constituting the ridgeline 7 and a V-grooved region 8 extended to both strip regions 9 and with the opening width gradually decreased from the bottom side 10 toward the top side 11. When such a crystal 6 is placed on a slide face, the flow resistance of a viscous lubricating oil is decreased on the slide face, and the lubricating oil flows smoothly. Consequently, the shear resistance of the lubricating oil film formed on the slide face is decreased, and the friction loss is reduced.

Filed: 1993-06-09
Abstract: The present invention relates to an image analysis method for determining the interior points of an object in a background when the contour, or perimeter points, of the object are known. By accessing the interior points of an object, textural and color information can be derived, thereby allowing for object recognition. Further, the ability to determine interior points of an object allows for complete identification of all objects in an image. By determining the interior points, one may "blacken out", or effectively remove previously identified objects from an image, creating a remainder image for further searching.
