Patent number: 8722602Abstract: Grease which includes a base oil containing at least 50% by mass of a specific diester compound of a glycol with a branched carboxylic acid, and a specific diurea compound as a thickener. The grease is excellent in low-temperature performance and has low oil separation tendency. In particular, when used in a rotation transmission device having a built-in one-way clutch, the grease can provide satisfactory clutch engagement performance (intermeshing) at low temperatures and is less apt to cause oil separation under high centrifugal force.Type: GrantFiled: October 24, 2007Date of Patent: May 13, 2014Assignee: Idemitsu Kosan Co., Ltd.Inventors: Yukitoshi Fujinami, Hitoshi Hata, Shinya Nakatani, Atsushi Yokouchi

Patent number: 8221346Abstract: The present invention relates to a blood sugar level control system equipped with an insulin dispensing device 2 and a blood sugar measuring device 3. An attachment mechanism 4 is provided which serves to couple the insulin dispensing device 2 and said blood sugar measuring device 3 in a relatively movable manner. Preferably, the attachment mechanism 4 is constructed so that the blood sugar measuring device 3 is movable or slidable with respect to the insulin dispensing device 2. A blood sugar level control system can be provided which includes a blood sugar measuring device and an insulin dispensing device without using an adapter. Accordingly, it is possible to avoid a cost rise due to an increase in the number of parts as required. In addition, it is possible to prevent the blood sugar level control system from being unable to be used due to the loss of an adapter in the form of a different part.Type: GrantFiled: April 24, 2009Date of Patent: July 17, 2012Assignee: Arkray, Inc.Inventors: Tetsuya Sakata, Yoshiharu Uehata, Hitoshi Hata
