Patent number: 10156218Abstract: An engine start system which may be employed in automotive idle stop systems. To start an engine, the system brings a pinion gear into engagement with a ring gear coupled to the engine and turns on an electric motor to rotate the ring gear through the pinion gear to crank the engine. When it is requested to start the engine during deceleration of the engine before stop thereof, the system thrusts the pinion into engagement with the ring gear and then turns on the motor to rotate the pinion gear, in other words, delays the activation of the motor until after the pinion gear has engaged the ring gear. This minimizes mechanical impact or noise arising from the engagement of the pinion gear with the ring gear and improves the reliability in engagement with the ring gear during the deceleration of the engine and durability of the system.Type: GrantFiled: July 2, 2015Date of Patent: December 18, 2018Assignee: DENSO CORPORATIONInventors: Mitsuhiro Murata, Hideya Notani, Shinji Usami, Mikio Saito, Yasuyuki Yoshida

Patent number: 10010834Abstract: A membrane separation device includes a separation membrane immersed in water to be treated and an air diffusion device positioned below the separation membrane, and provides treated water that has permeated through the separation membrane while diffusing air from the air diffusion device towards the separation membrane. A target value setting step sets a target value of an amount of diffusion air diffused from the air diffusion device based on a transmembrane pressure difference, and the air diffusion device is controlled such that the amount of the diffusion air becomes the target value. In the target value setting step, an absolute value of a change or a rate of change in the target value for increasing the amount of the air diffusion is set greater than an absolute value of a change or a rate of change in the target value for decreasing the amount of the air diffusion.Type: GrantFiled: September 25, 2014Date of Patent: July 3, 2018Assignee: Kubota CorporationInventors: Yasuyuki Yoshida, Yuji Ohtsuka
