Title: Suitcase with antitheft mechanism
Inventor: QI RUI CHENG
IPC: A45C5/03
Filed: 2018-06-07
Abstract: PROBLEM TO BE SOLVED: To provide a suitcase with an antitheft mechanism that eliminates the probability of attenuating acoustic energy and eliminates the probability of the antitheft mechanism being forgotten to be put in the suitcase.SOLUTION: When a suitcase becomes relatively apart from a portable terminal by a fixed distance (for example, 5 m) or more, a sound generation piece 22 generates warning sound. This warning sound is emitted to the outside while being hardly attenuated because the sound passes through holes of a porous plate 21 and passes through a through hole 36 of a lid shell 12. Supposing that an antitheft mechanism 20 is put in a suitcase in a tightly-closed state, warning sound is largely attenuated through the suit case, weakening a warning effect. With regard to this point, the warning sound is hardly attenuated, enhancing the warning effect. Because the sound generation piece and the like are normally provided on the lid shell, the possibility of forgetting to put the antitheft mechanism in the suitcase is eliminated.SELECTED DRAWING: Figure 3

Title: Coolant circulation device
Inventor: HIRATA TAKAYUKI
IPC: B24B55/03
Filed: 2018-06-12
Abstract: To provide a coolant circulation device which removes magnetic powders by a magnet separator from a coolant used for processing of a machine tool and supplies the coolant from which the magnetic powders are removed during processing of the machine tool, in which although sedimentation of sludge such as magnetic powders becomes slow and a storage tank which accumulates the coolant becomes large when foam is generated in the tank, down-sizing of the tank becomes possible by suppressing foam generation.SOLUTION: An outflow port 46 of a magnet separator 16, through which a coolant leaks into a clean tank 38, is so positioned as to be lower than a liquid level of the coolant in the clean tank 38 and to be immersed in the coolant. Thus, foam generation is suppressed when the coolant flows into the clean tank 38, and therefore, the clean tank 38 and a coolant circulation device 14 can be easily down-sized.SELECTED DRAWING: Figure 3
