Title: Rotor shaft
Inventor: SEKINE YUUJI
IPC: F16C13/02
Filed: 1984-07-06
Abstract: PURPOSE:To prevent cracks caused at both end portions of a cladding by welding portion by forming a notch groove at the end portion of a journal surface, forming a concave portion with a land left between the inner edge of the notch groove and the concave portion, and cladding by welding low-alloy steel in the concave portion. CONSTITUTION:A journal 2 and a flange 3 are integral with a rotor shaft 1. In this case, peripheral notch grooves 5 for intercepting transmission of stress are formed on both ends of the journal 2. A circular concave portion 6 is formed on a journal surface 2a of the journal 2, with lands 7 of an axial length from the inner edge 5a of the notch groove 5 left. A low-alloy steel 8 is cladded by welding in the concave portion 6. It is the inside surface B of the notch groove 5 that causes the maximum value of stress. As the inside surface B is not the end portion of the cladding by welding portion 8, but a strong portion of base metal of the rotor shaft 1, even if the maximum stress is caused, it is safe, and no crack is caused in the cladding by welding portion 8.

Title: Full-color projection device
Inventor: SHIMOMURA HIDEAKI
IPC: G02B27/18
Filed: 1995-06-07
Abstract: PURPOSE: To reduce astigmatism by arranging exit lights from respective optical modulation elements for R, G, B so as to enter dichroique mirrors for three color synthesis at incident angles smaller than a specific value. CONSTITUTION: Three color separating dichroique mirrors 6, 7 are set and arranged at incident angles smaller than 45 degree, for example, at almost 30 degrees with respect to incident lights. Projection lights of respective colors which are reflected and emitted after being modulated with modulation elements for respective colors are made incident on a three color synthesizing optical system by a Schlieren optical system in the optical system different from that of incident lights. The projection light emitted from the modulation element 1G is subjected to a two color synthesis with the projection light emitted from the modulation element 1R in the dichroique mirror 7 and the synthesized light is subjected to a three color synthesis with the projection light emitted from the modulation element 1B in the dichroique mirror 6.  The three color synthesized light is converged via an aperture 8 by a lens 4' to be projected on a screen 10 by a lens 4". Thus, the optical path difference between a meridional luminous flux and a sagittal luminous flux is made small and astigmatism is made small by setting the incident angles to the dichroique mirrors 6, 7 smaller than 45 degrees.

Title: Vane for compressor, and its manufacture
Inventor: OYA MASANORI
IPC: C23C14/32
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To obtain a film which shows the excellent wear resistance to the slide of a vane for a compressor and is free from any peels or chips by providing the vane of the composite structure which consists of the metallic chromium and CrN type chromium nitride, and in which the metallic chromium is distributed all over the film. SOLUTION: The probability of colliding of the metallic chromium ion particles evaporated from a first target 16 with the nitrogen molecules to be introduced from a reactive gas inlet 12 is low since the distance from the first target to the surface of a work body 21 is small, and the metallic chromium can be precipitated on a work in the metallic condition by appropriately selecting the gas pressure and the distance. The probability of colliding the metallic chromium ion particles evaporated from a second target 18 with the nitrogen molecules is high because the distance from the second target to the surface of the work body 21 is large, and the mixture of CrN type chromium nitride can be precipitated.  The film is formed by selecting the gas pressure to fix the second target 18 at the distance where chromium nitride is formed, and to fix the first target 16 at the distance where the metallic chromium is precipitated.
