Patent number: 6537181Abstract: A clutch control device of a continuously variable transmission is provided with a clutch control part, which controls the engagement state of a clutch. The minimum engaging force, which is capable of maintaining the completely engaged state of the clutch, is predetermined to increase according to an increase in engine torque. The clutch control unit has an engaging force setting part, which sets the target engaging force for the clutch to a higher value than the minimum engaging force by a predetermined value. The clutch control unit controls the engagement state of the clutch so that the actual engaging force for the clutch can be higher than the minimum engaging force by the predetermined value. Therefore, the clutch control device can improve the fuel economy and prevent a shift shock when there is a rapid increase in the engine torque.Type: GrantFiled: March 8, 2001Date of Patent: March 25, 2003Assignee: Mitsubishi Jidosha Kogyo Kabushiki KaishaInventors: Hiroki Asayama, Kaoru Kondo, Toru Hashimoto, Minoru Shouichi

Patent number: 6533702Abstract: A shift control system of a hydraulic CVT for an automotive vehicle with which it is possible to control a speed ratio to a target value with certainty while maintaining a required primary pressure, even when the vehicle is substantially stationary. Normally, a speed feedback control means sets a target speed of a rotating element on the basis of the vehicle speed and the load on the vehicle engine. The speed feedback control means feedback-controls a hydraulic pressure control means of the rotating element so that the actual speed approaches the target speed. When the vehicle becomes substantially stationary, control of the hydraulic pressure control means is switched from the speed feedback control executed by the speed feedback control means to pressure feedback control executed by a pressure feedback control means. That is, the actual hydraulic pressure acting on the rotating element is detected by a hydraulic pressure detecting means.Type: GrantFiled: November 22, 2000Date of Patent: March 18, 2003Assignee: Mitsubishi Jidosha Kogyo Kabushiki KaishaInventors: Hiroki Asyama, Kaoru Kondo, Toru Hashimoto, Minoru Shouichi

Patent number: 4809885Abstract: A highly-viscous material coating apparatus for use, e.g. in an automobile coating process, to coat a joint of a workpiece, may be mounted on a robot. It provides improved operation where the workpiece provides a reference surface parallel to the joint, where the workpiece provides a reference surface displaced from the joint at varying distances along the length of the joint, and where the workpiece provides no reference surface. Where a reference surface is available, an extendable spring-biased guide pin of the apparatus moves along the reference surface, and any positional errors are compensated-for by action of the spring. If the distance between the reference surface and the joint varies, the varying distance may be compensated for by various disclosed practices. The apparatus also can be used where no reference surface is provided by retracting the guide pin with respect to the nozzle and by controlling the robot so as to direct the nozzle to the joint.Type: GrantFiled: September 17, 1987Date of Patent: March 7, 1989Assignee: Toyota Jidosha Kabushiki KaishaInventors: Sensuke Hayashi, Yasuo Tokushima, Kouji Ota, Hirofumi Hashimoto, Kajuyosi Utiyama, Masahiro Umeda, Kaoru Kondo, Yosifumi Kaji
