Patent number: 8718518Abstract: A development roll for electrophotographic equipment includes a shaft body, a rubber elastic layer formed by molding on an outer circumference of the shaft body and having many convex portions formed by transfer molding on the outer circumferential surface thereof, and a coating layer disposed on an outer circumference of the rubber elastic layer. The coating layer is composed of a cured body of a coating material containing (A) a thermoplastic urethane having a number-average molecular weight in the range of 50,000 to 200,000, (B) a polyol having a number-average molecular weight in the range of 500 to 4,000, and (C) a curing agent. The mass percentages a, b, and c of the components (A), (B), and (C) satisfy the following expressions: a+b+c=100, 40?a?75, 5?b?20, and 20?c.Type: GrantFiled: August 6, 2012Date of Patent: May 6, 2014Assignee: Tokai Rubber Industries, Ltd.Inventors: Shuichi Egawa, Masanari Umeda, Yousuke Hayashi

Patent number: 8545365Abstract: An apparatus comprises a changeover mechanism which is able to change a connection state of an electric motor output shaft to any one from alternatives consisting of “an IN-Connection State” in which a power transmission path is provided between a transmission input shaft and the electric motor output shaft, “an OUT-Connection State” in which a power transmission path is provided between the transmission output shaft and the electric motor output shaft, and “a neutral connection state” in which no transmission path therebetween is provided. The changeover is carried out based on a combination (area) of a vehicle speed V and a required driving torque T. As for the changeover, an (first, second) IN-connection area is more enlarged and the OUT-Connection area and the neutral connection area are more narrowed, as a temperature of a lubricating oil is lower.Type: GrantFiled: March 10, 2010Date of Patent: October 1, 2013Assignee: Aisin AI Co., Ltd.Inventors: Takeshige Miyazaki, Hiroki Hatori, Kan Sasaki, Toshio Tanba, Yousuke Hayashi

Patent number: 8480535Abstract: A hybrid-type power transmission in which an internal combustion engine and an electric rotating machine are used as a source of power for driving an output shaft through a change-speed mechanism. In the hybrid power transmission, the operation of the electric rotating machine is controlled in such a manner that the rotation speed of a rotor-side rotary member is synchronized with the rotation speed of an input-side or output-side rotary member when the rotation speed of the rotor-side rotary member becomes higher in a predetermined difference than the rotation speed of the input-side or output-side rotary member in shifting operation of a sleeve coupled with the rotor-side rotary member.Type: GrantFiled: February 3, 2010Date of Patent: July 9, 2013Assignee: Aisin Ai Co., Ltd.Inventors: Toshio Tanba, Kan Sasaki, Yousuke Hayashi, Yuichi Fukuhara

The changeover is carried out based on a combination (area) of a vehicle speed V and a required driving torque T. As for the changeover, a neutral area is enlarged so that a possibility of selecting the neutral state becomes higher, as a battery temperature is higher, or as an electric motor temperature is higher, or as a remaining battery level is larger.Type: GrantFiled: March 10, 2010Date of Patent: March 5, 2013Assignee: Aisin AI Co., Ltd.Inventors: Takeshige Miyazaki, Hiroki Hatori, Kan Sasaki, Toshio Tanba, Yousuke Hayashi

Patent number: 8352139Abstract: An apparatus comprises a changeover mechanism which is able to change a connection state of an electric motor output shaft to any one of “an IN-Connection State” in which a power transmission path is provided between a transmission input shaft and the electric motor output shaft, “an OUT-Connection State” in which a power transmission path is provided between the transmission output shaft and the electric motor output shaft, and “a neutral state” in which no transmission path therebetween is provided. When a kick-down-condition is satisfied, a changeover operation for changing an electric motor connection state to the OUT-Connection State is firstly performed. Thereafter, a gear position shifting operation for increasing a transmission reduction ratio is performed. After the kick-down-condition satisfied, an E/G side output torque Te and a M/G side output torque Tm is adjusted in such a manner that a sum Ts of Te and Tm continues to increase.Type: GrantFiled: April 6, 2010Date of Patent: January 8, 2013Assignee: Aisin AI Co., Ltd.Inventors: Hiroki Hatori, Takeshige Miyazaki, Kan Sasaki, Toshio Tanba, Yousuke Hayashi
