Title: System and method for interpolating curved surface
Inventor: MIURA KENJIRO
IPC: G06T19/00
Filed: 1995-02-10
Abstract: PURPOSE: To interpolate a rectangular area adjacent to an nth-order meromorphic Bezier patch so that a curvature can be continued by judging whether the conditions for continuing a contact plane and the curvature are satisfied or not concerning that rectangular area and performing the interpolation of a curved surface patch and the deformation processing of a boundary corresponding to the result. CONSTITUTION: Concerning the rectangular area adjacent to the nth-order meromorphic Bezier patch, the conditions for linking the contact planes are judged (11). Next, when it is judged that those conditions for continuing the contact planes are satisfied, one part of curved surface patch is interpolated (12). Continuously, the conditions for continuing the curvatures are judged (13) and when it is judged that those conditions are satisfied, the remaining part of curved surface patch is interpolated (14). When it is judged that the respective conditions of contact plane continuation and curvature continuation are not satisfied, the deformation processing of a border curved line is performed (15 and 16). Therefore, the rectangular area adjacent to the nth-order meromorphic Bezier patch can be easily interpolated so that the curvature can be continued.

Title: Erosion resistant member for molten aluminum
Inventor: KAMATA KEIICHI
IPC: C23C2/12
Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To improve the erosion resistance and impact resistance of the member by oxidizing the surface of a ferrous alloy material contg. a specified amt. of Si and controlling the depth of an oxidized film layer to the specified one. SOLUTION: The surface of a ferrous alloy or ferrous alloy material build-up welding layer contg. 2 to 10 wt.% Si is oxidized by 2 to 20 μm. In this way, a coating of silicon oxide is formed, which prevents erosion caused by molten aluminum to improve its erosion resistance. Moreover, the silicon oxide is excellent in impact resistance as well. As for the content of Si in the ferrous alloy or the like, in the case of being below the lower limit value, erosion can not be prevented, and, in the case of being above the upper limit value, the oxidized film in the surface is made easy to be cracked. Furthermore, as for the depth of the oxidized film, in the case of being below the lower limit, erosion can not be prevented, and, in the case of being above the upper limit value, its impact resistance is made inferior.  The formation of the oxidized film onto the ferrous alloy or the like can be executed by heating at 650 to 900 deg.C for about 0.5 to 3 hr in the air or in an oxidizing atmosphere or by heating by a gas burner in the case of a small-sized member.

Title: Go-ahead/go-astern switching device for inboard/outboard motor
Inventor: OSHIRO KENJI
IPC: F02B61/04
Filed: 1993-01-18
Abstract: PURPOSE:To instantly feed the comparatively plenty of pressure oil to an oil passage by connecting an accumulator to the oil passage connecting a hydraulic oil chamber which intermittently connects two clutches for going-ahead and going-astern, to an oil pump. CONSTITUTION:When the go-ahead/go-astern switching lever 48 of a go-ahead/ go-astern switching device 20 is in a neutral position, a hydraulic changeover valve 45 allows almost all the amount of working oil to be recirculated to a tank through a pressure adjust valve. When the go-ahead/go-astern switching lever 48 is in a position for either going-ahead or going-astern, working oil delivered out of a hydraulic pump 38 is fed to either one of multi-plate clutches 30a and 30b for going-ahead or going-astern. In this case, since the plenty of working oil must be instantly fed to the multi-plate clutches 30a and 30b, hydraulic pressure at the delivery side of the hydraulic pump 38 becomes low, therefore, a part of pressure oil accumulated in an accumulator 50 is fed to the multi-plate clutches 30a and 30b. The hydraulic pump is therefore, not necessarily of a great capacity, the aforesaid constitution can contribute much to the success of making the device light in weight.
