Patent JP-H04172672-A (JP)
Title: Optical information disk
Inventor: OKADA NORITOMO
IPC: G11B7/24097
Filed: 1990-11-05
Abstract: PURPOSE:To prevent the occurrence of double refraction in a disk caused by a residual stress and the occurrence of cracks in a stuck section due to a residual solvent by inserting the projecting section of a face-A hub into the joining projecting section inserting hole of a disk substrate and putting the recessed section of a face-B hub on the projecting section from the opposite side of the disk substrate, and then, sticking the recessed and projecting sections to each other with a quick-drying solvent. CONSTITUTION:After the joining projecting section of a face-A hub 3 is inserted into the joining projecting section inserting hole of a disk substrate 2, the joining recessed section of a face-B hub 4 containing a quick-drying solvent put in the recessed section in advance is put on and stuck to the fitting section of the joining projecting section protruded from the substrate 2. Any kind of quick- drying solvent which can dissolve the used resin, such as 1,2-dichloroethane, can be used as the quick-drying solvent. Therefore, the occurrence of double refraction in the disk 2 caused by a residual stress can be prevented, since the hubs 3 and 4 are not stuck to each other for forming the disk substrate 2, and the occurrence of cracks or a decline in the adhesive strength can be prevented, since no residual solvent is produced.

Title: Method for obtaining pressure distribution in fluid
Inventor: KAWAMOTO SHINJI
IPC: G06F17/10
Filed: 1994-11-09
Abstract: PURPOSE: To improve the accuracy for estimating the pressure distribution without increasing calculation costs (calculation time) by decreasing the energy of a turbulent flow of a fluid with the use of an anisotropic rate by which anisotropic data related to the turbulence of the fluid are moved. CONSTITUTION: An anisotropic rate ϕ is a variable that can vary from 0 to 1 indicating how much a production term of a turbulence energy (k) in a transportation equation ((k) equation) representing the turbulence energy (k) by a fluid shifts from a standard model of k-ε (ε is a lost ratio of the energy (k)). When a new transportation equation representing the anisotropic rate ϕ(ϕ equation) is used, the production term of the turbulence energy (k) in the (k) equation is adjusted and a value of the turbulence energy (k) is decreased. Moreover, when the anisotropic rate ϕ is multiplied by the sum of vertical stress components and shearing stress components in the production term of the turbulence energy (k), errors are removed and the turbulence energy (k) close to an actual value can be obtained.  Accordingly, an estimated value of the pressure distribution close to an experimental value can be obtained even in an area of a butting flow, a normal pressure gradient flow and an inverse pressure gradient flow.
