摘要:
A dilurea grease composition contains a lubricant base oil and a thickener. The thickener essentially consists of a mixture of at least two diurea compounds each being represented by the following general formula (I) of: ##STR1## wherein R.sub.1 is a difunctional aromatic hydrocarbon residue, and A and B each stands for an amino group represented by the general formula (II) of R.sub.2 --NH--(where R.sub.2 stands for a cyclohexyl group, a group derived from cyclohexyl or an alkyl group) or an amino group represented by the general formula (III) of ##STR2## (where R.sub.3 R.sub.4 each stands for cyclohexyl group or a group derived from cyclohexyl). The ratio in percentage of the numbers of the amino groups (III) to the total numbers of the amino groups (III) plus the amino groups (II) ranges from 1 to 50%. The ratio of the numbers of the amino groups (II) wherein R.sub.2 is a cyclohexyl group or a group derived from the cyclohexyl to the numbers of the amino groups (II) wherein R.sub.2 is an alkyl group ranges from 174 to 4/1.

摘要:
The present invention provides an image processing apparatus and an image processing system which facilitate management against unauthorized use by creating a job log according to a usage status of a user. A creation section creates a different job log for each individual user. The job log has storage conditions of image data included in the job log set according to a storage level. The storage conditions are a color of an image, a resolution of the image data and whether or not necessary to create OCR data of the image data. To increase efficiency of a follow-up research by using such a job log, the storage level of the image data relating to the user having performed unauthorized use is raised.
摘要:
Mobile apparatuses capable of moving or acting autonomously, without contacting each other, in an environment where movements of the mobile apparatuses are not managed by a server are provided. In a robot functioning as a first mobile apparatus, it is recognized that an object corresponds to a second mobile apparatus, and based on this recognition, a target trajectory is searched for and determined. Further, the first mobile apparatus causes another robot functioning as the second mobile apparatus to recognize a part or a whole of the target trajectory. In the second mobile apparatus, the part or the whole of the target trajectory of the first mobile apparatus is recognized, and based on this recognition, a target trajectory that the second mobile apparatus should follow is searched for and determined. This allows the mobile apparatuses to move along their respective target trajectories to avoid contact with each other.
