Title: Intersection calculation system between sculptured surfaces
Inventor: SHINOHARA KATSUYA
IPC: G06T19/00
Filed: 1989-06-19
Abstract: PURPOSE:To dispense with the dynamic management of a memory and to heighten the parallelism of a processing in calculation by eliminating recursive split when performing the calculation of a straight line with an intersection, and factorizing a curved surface to curved surface patches represented in a single polynomial. CONSTITUTION:First and second natural number pair generating means 10 and 20 generate a pair of natural numbers (1,1), and sends them to a curved surface patch generating means 30. The generating means 30 finds the partial string of a knot vector corresponding to curved surface data and the natural number and 16 control points, and sends them to a mini/max box generating means 40, a comprehensive rectangular parallelopiped generating means 60, and an inter-patch intersection calculation means 80. The mini/max box generating means 40 finds the mini/max boxes of the 16 control points, and sends them to a box judging means 50. The judging means 50 judges the intersection of both sent mini/max boxes. When no intersection is obtained, the fact is informed to the second natural number pair generating means 20 and the inter patch intersection calculation means 80.

Title: Low-noise gear device
Inventor: MORIKAWA KUNIHIKO
IPC: F16H1/20
Filed: 1988-06-24
Abstract: PURPOSE:To decrease a gear noise by arranging each gear shaft in a manner, wherein a phase difference on a work line of meshing between 1 and 2-shaft gears and between 2 and 3-shaft gears is formed to a half of the transverse base pitch, in the case of a three-shaft parallel gear device having the 1 and 3-shaft gears of equal number of teeth. CONSTITUTION:Vibration by meshing a helical gear 1a of 1-shaft with a helical gear 2a of 2-shaft and vibration by meshing the helical gear 2a of the 2-shaft with a helical gear 3a of 3-shaft are generated. Since a changing period of spring rigidity of a tooth, causing these vibrations, corresponds to the transverse base pitch 7a, a phase difference on a work line of meshing between the gear 1a of the 1-shaft and the gear 2a of the 2-shaft and between the gear 2a of the 2-shaft and the gear 3a of the 3-shaft is set to 1/2 times the transverse base pitch 7a on the same work line 5b. In this way, also a waveform of spring rigidity of the tooth, causing the vibration, mutually generates a 1/2 period phase-shifted function, obtaining the waveform of reverse phase so as to mutually negate both the vibrations, and a gear noise is decreased as a device total unit.

Title: Sealing structure for vacuum vessel, etc.
Inventor: MASUDA YOSHIO
IPC: F16J15/06
Filed: 1990-06-15
Abstract: PURPOSE:To secure high sealability in either case; the initial stage of decompressing treatment and at time of the inside of a vessel kept in a high vacuum by installing both soft and hard gaskets in either of the vessel or sealed member or both separately. CONSTITUTION:At a stage where a dryout processing chamber 3 is being decompressed, first it is in such a state as shown in (a), but when decompressing treatment is slightly advanced, a soft gasket 16 installed in a flange 13 sticks fast to the side of a cover body 5, but a hard gasket 17 will not come into contact with this cover body 5 or if contacting with this cover body, it comes to such a state as not serving as a sealing action in substance. Consequently at the initial stage of decompressing treatment, only the soft gasket 16 conduces to this sealing action, and since its deformability is large enough, a high sealability is kept up. In addition, when the decompressing treatment is further advanced, the soft gasket 16 is further deformed, while the hard gasket 17 comes to stick fast to the cover body 5, thus still more sealability is made securable.
