Abstract: A cutting fluid circulation device includes a tank reservoir, a drum filter, and a pump. The tank reservoir stores cutting fluid discharged from a machine tool. The drum filter is disposed in the tank reservoir. The drum filter performs as a primary filter that filters cutting fluid. The pump pumps up cutting fluid in the tank reservoir. An annular flow channel in which the cutting fluid filtered by the drum filter circulates is formed in the tank reservoir. A part of the cutting fluid pumped up by the pump is fed to the drum filter, used for cleaning the drum filter, and then returned to the annular flow channel, and a part of the remaining cutting fluid is fed to a secondary filter disposed outside the tank reservoir, filtered by the secondary filter, and then returned to the annular flow channel.

Abstract: Provided is a novel low-molecular-weight compound that suppresses production of induction type MMPs, particularly MMP-9, rather than production of hemostatic type MMP-2. The present invention relates to a compound represented by the following formula (I): wherein each symbol is as described in the DESCRIPTION. The compound has a selective MMP-9 production suppressive action, and is useful as a drug for the prophylaxis and/or treatment of autoimmune diseases such as rheumatoid arthritis and the like, inflammatory bowel diseases (ulcerative colitis, Crohn's disease) or osteoarthritis.

Abstract: A card processing apparatus includes a card insertion opening, and a card insertion detection sensor. A magnetic card is to be inserted in the card insertion opening. The card insertion detection sensor is configured to detect the magnetic card inserted in the card insertion opening. A magnetic head is provided near the card insertion opening and is configured to detect a change in an electromagnetic field and output a magnetic signal. A control unit is configured to: receive the magnetic signal from the magnetic head when the card insertion detection sensor detects the magnetic card; receive magnetic signal from the magnetic head when the card insertion detection sensor does not detect the magnetic card; acquire the magnetic signal when the magnetic signal includes a predetermined pattern; and discard the magnetic signal when the magnetic signal does not include the predetermined pattern.
