IPC: B02C23/32
Filed: 1988-04-11
Abstract: PURPOSE:To prevent interruption of flow of particles and wear of blades as well, by providing an annular body which connects blades around the center of rotation. CONSTITUTION:Blades 1 are connected to a lower cone 5 constructed on a rotor 7 in a framework manner and on the peripheries of upper spokes 6 through lower fixing plates 3 and upper fixing plates 4 for blades respectively approximately in vertical direction so as to encircle the rotor 7, wherein a reinforcing ring 2 passes horizontally through the middle part of each of the blades 1 to connect them with each other. When the rotor 7 rotates, centrifugal forces acting on the blades 1 exert outward loads thereon so as to cause deflection in the central portion of the blade; however, such deflection is avoided by the reinforcing ring 2. Consequently, area of the opening between adjacent blades 1 in the direction of flow of particles can be made greater, resulting in improved classification property.

Title: Flattened seat structure of automobile
Inventor: ARAI TOMIJI
IPC: B60N2/36
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To flatten a seat even if there is no space in front of the seat. SOLUTION: When a seat cushion 7 rotates centered on a front end part fulcrum P2, the front end part fulcrum P2 itself moves backward using a fixed fulcrum P1 as a reference. An amount of forward protrusion when the seat cushion 7 becomes a substantially horizontal inversion condition moves backward by double an interval L between the front end part fulcrum P2 and the fixed fulcrum P1. Consequently, the seat structure can be applied even to an automobile having no space in front of a seat.

Filed: 1983-05-17
Abstract: PURPOSE:To enable the distinguishing of actual defects from false ones by generating inspection signals from the surface to be inspected under blowing condition to compare the inspection signals in the same scan line, provided that they are the same in the scanning direction but different in the scanning timing. CONSTITUTION:A scanning means scans a surface to be inspected of a sample reciprocally by a scan light and a blowing means blows air against the surface being inspected to remove floating dust or the like attached thereto during the inspection. In addition,an inspection signal generating means 4 generates an inspection signal for voltage corresponding to the intensities of reflected lights and transmission lights from the surface being inspected. Decision means 13-16 decides that a defect exists on the surface being inspected when two inspection signals in the same scan line from the surface being inspected coincide by comparison, provided that they are the same in the scanning direction but different in the scanning timing. Thus, actual defects and can be distinguished from false defects due to floating dusts attached to the surface during the inspection.

Filed: 1989-04-10
Abstract: PURPOSE:To heighten reliability of a wiring layer while improving a coating property by using a compound of Al, Ti and Si between diffusion layer and a wiring layer as well as between the lower and upper wiring layers. CONSTITUTION:A contact hole 4 is made through an insulating layer 3 of a diffusion layer 2 of an Si substrate 1. This contact hole is covered with a polysilicon film 5 by reduced pressure CVD while piling up Ti 6 and Al 7 by sputtering. Leaving lamination only in the position of the hole 4, the other part is removed by plasma etching. When polysilicon 5, Ti 6 and Al 7 are treated at 470 deg.C for 90min for being alloyed, volume is contracted to form Ti7Al5Si12 or the like so that alloying can be easily performed to an oblong contact hole 4. Reaction of Al 10 to an alloy layer 8 is prevented by covering with TiN 9 for being protected by Si3N4 11 to be finished. By this constitution, the Al film 10 is excluded from becoming a thin film at a part of the contact hole 4 so that reliability of wiring is improved besides a coverage of the protective film 11 is improved while preventing infiltration of an impurity from outside to improve reliability of a semiconductor element.
