Abstract:
A prior simulation of a velocity field and a temperature field is carried out, and snapshot data of the velocity field and that of the temperature field are collected during the prior simulation. Then principal component analysis on the collected snapshot data obtains velocity-field and temperature field dimension transformation matrixes, on the based on which the analysis models of the velocity field and temperature field having respective first degrees of freedom are converted into reduced degree-of-freedom models. Consequently, a simulation of the velocity field and the temperature field is carried out using models having respective reduced degrees of freedom (i.e., second degrees of freedom).
Abstract:
A battery device that functions as a power source of a tool main body and is attachable to a body of a user may include a battery housing that is capable of removably receiving at least one rechargeable battery and capable of being electrically connected to the at least one battery, an adaptor that is capable of being electrically connected to the tool main body, and a cable electrically connecting the battery housing and the adaptor. The battery housing comprises a housing body that is constructed to be attached to the body of the user and is capable of receiving the at least one battery therein, and a cover member that is openably and closably attached to the housing body. The housing body and the at least one battery are connected to each other via a male-female engagement device. The male-female engagement device has an engagement release portion that is positioned so as to be exposed when the cover member is opened relative to the housing body.
Abstract:
An apparatus and method for supporting harness design. Harness information including a pass position of a harness is set on a three-dimensional model. Then, it is determined whether the harness whose position is decided so as to pass through the set pass position interferes with a mechanical part that is read from a storing unit that stores therein three-dimensional model data on the mechanical part through which the harness passes. When it is determined that the harness interferes with the mechanical part, from among a plurality of surfaces of the mechanical part, a surface that has not been selected is selected, and a pass position of the harness is set outside the selected surface. Then, a position of the harness that passes through the set pass position is decided. These processes are repeated until it is determined that the harness does not interfere with the mechanical part.
Abstract:
A fluorine-containing polymer comprising a fluoroalkyl alcohol (meth)acrylic acid derivative represented by a general formula, CnF2n+1(CH2CF2)a(CF2CF2)b(CH2CH2)cOCOCR═CH2 (in the formula, R is a hydrogen atom or a methyl group, n is an integer of 1 to 6, preferably 2 to 4, a is an integer of 1 to 4, b is an integer of 0 to 3, and c is an integer of 1 to 3) containing in 5 to 100 wt % as a polymerization unit. A organic solvent solution or aqueous dispersion of the fluorine-containing polymer is effectively used as, for example, a surface-modifying agent such as a water- and oil-repellent or an oil barrier.
Abstract:
A biopolyester which is poly(3-hydroxyalkanoate) or poly(3-hydroxyalkanoate) copolymer and has a reduced calcium content. It has improved thermal stability due to the reduced calcium content.
Abstract:
In the event of modifying analysis condition, after the simulation of a first time step carried out when the analysis condition is modified finishes and before the simulation of a second time step next after the first step starts, the modified analysis condition is referred and the simulation based on the modified analysis condition is carried out in the next time step.
Abstract:
An object is to provide a liquid level sensor device for liquefied gas enabling measurement on a liquid level of liquefied gas having a boiling point in the vicinity of 21 K, e.g. liquid hydrogen, accurately and with good reproducibility and enabling simple production with good reproducibility. The present invention is a liquid level sensor device for liquefied gas including compound containing magnesium and boron arranged in succession in the longitudinal direction over the entire or a part of surface of a linear conductor made of metal and a portion of the compound thereof dipped in liquid is in a superconductive state at liquid level measurement.
