Publication number: 20150081466Abstract: To reduce bothers related to back-in-stock notification of an item. Arrival notice request receiving means of a notification control system receives from a user a request for an arrival notice of an item. In a case where the item arrives, arrival notifying means notifies the arrival to the user whose arrival notice request has been received. Stock determining means determines whether or not the item is in stock in the case where the user whose arrival notice request has been received accesses an item page of the item after the item arrives. Back-in-stock notification control means controls back-in-stock notification of the item to the user whose arrival notice request has been received, based on the result of the determination by the stock determining means.Type: ApplicationFiled: August 5, 2013Publication date: March 19, 2015Inventor: Yusuke Sakurai

Patent number: 6193488Abstract: In a scroll type compressor, the center and outer periphery portions of the spiral elements are provided with relief for preventing the mutual contact of the spiral elements. Both of the spiral elements come to contact with each other at the intermediate portion thereof. The relief at the center portion is formed within the range defined by the winding angle Y=32(X−1) where X is the winding turn of each of the spiral elements. The range of the intermediate portion is 380°. This construction serves to prevent the excessive pressure increase of the operation chamber at the center portion so that the brake down of the spiral elements may be prevented without lowering the efficiency of the compressor.Type: GrantFiled: June 9, 1999Date of Patent: February 27, 2001Assignee: Denso CorporationInventors: Haruo Kamiya, Yusuke Sakurai, Tsuyoshi Takemoto, Kimihiko Sato
