Abstract:
The purpose of the present invention is to provide a method for producing a high quality biodiesel fuel having excellent oxidation stability and few low-temperature deposits. This purpose can be achieved by the following: hydrogenating a biodiesel fuel so as to selectively convert unsaturated fatty acid monoglycerides and then removing fatty acid monoglycerides through precipitation; or using an adsorbent to further remove fatty acid monoglycerides to a high degree from the biodiesel fuel produced using the method mentioned above.

Abstract:
To provide: a package suitable for housing a precision mechanism such as a micro-electrical-mechanical system (MEMS) in a hollow-sealed interior space; and a method for forming the package. This invention includes a sacrificial thin film formation step for chemical-mechanical polishing a temporary substrate made of a readily polishable material and sputtering a metal thin film along the smoothly polished surface, and a first bonding step for forming a sealing frame obtained by bringing at least a noble metal on the metal thin film and bonding a substrate on the sealing frame. This invention also includes: a temporary substrate removal step for then removing the metal thin film along with the temporary substrate and exposing a new surface at the tip of the sealing frame; and a second bonding step for sputtering a noble metal thin film around a precision machine element on the machine substrate, bringing the new surface of the sealing frame into contact onto the noble metal thin film and bonding the new surface of the sealing frame onto the noble metal thin film at room temperature. A package obtained using this method can maintain an internal vacuum state of at least 10 -4 Pa for six months.
Abstract:
An angle detecting device with a self-calibration function is also provided with an axis run-out measuring function, so that various kinds of setups to an engine, a drive shaft of an automobile, and the like, can be made readily. The angle detecting device with the self-calibration function is used, in which a plurality of sensor heads is provided with an equiangular interval at a circumference of a scale disc fixed to a rotating shaft, and when one of the sensor heads is selected as a reference sensor head, a sum of measurement differences between the reference sensor head and the other respective sensor heads, and this sum is divided by the number of sensor heads, to determine an average value, whereby a self-calibration value is obtained. Further, a sensor head selected as the reference sensor head is changed to another sensor head in order, and each of the self-calibration values for all the sensor heads is obtained where each of all the sensor heads is adopted as the reference head. Then, each of the self-calibration values is deviated by an angle in terms of arrangement with respect to a particular sensor head, and a phase is aligned to a self-calibration value where the particular sensor head is adopted as the reference head. Then, an average value for all the calculation results of the phase converting is obtained, and the average value is subtracted from each of the calculation results having been subjected to the phase conversion, to obtain only asynchronous angular errors.
Abstract:
An object of the present invention is to improve durability of a pressure vessel for blasting an article to be treated such as hazardous substance or explosive therein. The pressure vessel 10, means for achieving the object, has an external vessel 31 and an internal vessel 32 installed in the external vessel 31. The external vessel 31 has a strength for retaining pressure caused by blasting the article. The internal vessel 32 receives fragments of the treated article 100 to protect the external vessel 31 against the fragments. The internal vessel 32 preferably covers almost entire internal surface of the external vessel 31.

Abstract:
In this production method, to produce a carbon particle via the detonation method, an explosive substance having a detonation velocity of 6300 m/s or faster is disposed around a raw material substance containing an aromatic compound having two nitro groups or less, and the explosive substance is detonated. This production method allows carbon particles containing nano-scale graphite carbon and diamond to be produced via a detonation method using a non-gunpowder raw material. In addition, the obtained carbon particles have a G/D mass ratio of 2.5 or greater, where G is the graphite carbon mass and D is the diamond mass.
