  • Patent number: 11058280
    Abstract: Disclosed herein is useful as a stored object detector and a method of detecting stored objects configured to capture an image a movable storage portion, and objects stored in the storage portion, and configured to acquire storage information including at least one of position, size and quantity of the stored object based on the captured image. In addition, disclosed herein is a dishwasher configured to identify at least storage area of dish stored in a dish storage basket. It is possible to estimate a position of a basket, although the number of feature points is small. Therefore, when installing a detection indicator corresponding to the feature point, which is separated from the general configuration, to the basket, it is not required to install a large number of detection indicator, and thus it is possible to improve the appearance of the dishwasher.

  • Patent number: 7858348
    Abstract: The present invention provides genes that encode the N-acetyl-(R,S)-?-amino acid acylases. The N-acetyl-(R,S)-?-amino acid acylases were isolated and purified from bacterial cells and the nucleotide sequences were determined. A host, such as Escherichia coli, was used to construct a high-expression system for these genes. The N-acetyl-(R)-?-amino acid acylase produced by Burkholderia sp. AJ110349 (FERM BP-10366) includes, for example, the protein having the amino acid sequence shown in SEQ. ID. NO. 8. The gene encoding this enzyme includes, for example, the DNA having the nucleotide sequence as shown in SEQ. ID. NO. 7. The N-acetyl-(S)-?-amino acid acylase produced by Burkholderia sp. AJ110349 (FERM BP-10366) includes, for example, the protein having the amino acid sequence shown in SEQ. ID. NO. 10. The gene encoding this enzyme includes, for example, the DNA having the nucleotide sequence shown inshown in SEQ. ID. NO. 9. The N-acetyl-(R)-?-amino acid acylase produced by Variovorax sp.
