Filed: 1992-05-11
Abstract: PURPOSE:To obtain a buffer material which does not cause environmental pollution and which can be returned to the earth after use, by integrating a lot of swelled grains and molding them to form an appropriate shape. CONSTITUTION:Food grains such as coan, rice, many kinds of barley, soybeans, red beans, etc., for instance which retain appropriate water and swell and foam by the steam pressure on heating are utilized. Swelling is a phenomenon that the water content in the structure of the sereals is evaporated when they are suddenly released to a lower pressure after they are retained in a high temperature and pressure vessel until the temperature is sufficiently raised and the structure swells by the expansive pressure of the steam at the moment and the swelling is carried out by means of devices like a batch type buff gun. The grains swelled in such a way are integrated by use of an adhesive like gum arabic to obtain a required degradable buffer material by molding them with a mold frame 2 comprising upper and lower frames 3, 4.

Title: Method and apparatus for inspection of abnormal sound of rotating machine
Inventor: KURIKAWA YOSHIHARU
IPC: G01M99/00
Filed: 1996-06-21
Abstract: PROBLEM TO BE SOLVED: To acquire required data inside a simple soundproof chamber into which the background noise of a factory does not creep by a method in which it is judged that a noise is mixed when a change in the statistical amount of data on an operating sound exceeds a prescribed threshold value. SOLUTION: A noise detection means 6 detects a noise, other than an operating sound, on the basis of sample data to be input from an A/D converter 5, and the data is excluded from a sample when the noise is detected. That is to say, a rotation-cycle estimation means 14 estimates the rotation cycle of a compressor (a rotating machine), and a computing means 15 computes a change in the statistical amount of data on the operating sound of the compressor. In addition, a discrimination means judges that a noise is mixed when the change in the statistical amount exceeds a prescribed threshold value. A frequency analysis means 7 executes a frequency analysis to the sample data so as to be expressed as a power spectrum.  In this manner, the noise which is generated suddenly so as to influence its discrimination is detected so as to be discrminated from the operating sound, and an abnormal sound can be detected surely and automatically.
