Patent number: 10914422Abstract: A grease discharge device includes a motor, a plunger, a grease supply unit, a pump, a check valve, and a relief valve. The plunger reciprocates by driving of the motor. The grease supply unit supplies grease to a forward movement side with respect to a backward movement side dead center of the plunger. The pump performs a discharge behavior of the grease by the reciprocation of the plunger. The check valve is disposed at a downstream side with respect to a forward movement side dead center of the plunger in a discharge path of the grease inside the pump. The relief valve is disposed between a supply portion of the grease by the grease supply unit and the check valve. The relief valve releases the grease inside the discharge path to the grease supply unit side according to a pressure rise inside the discharge path.Type: GrantFiled: April 26, 2018Date of Patent: February 9, 2021Assignee: MAKITA CORPORATIONInventors: Tomofumi Kawai, Akihito Hara, Koji Tanaka, Yuki Miwa

Patent number: 10584894Abstract: Air-blowing from a second air outlet is effectively used. An air conditioner includes a main body unit and an auxiliary housing. The main body unit forms a first air outlet which blows out a cool or warm airflow. The auxiliary housing is attached to at least one side of the first air outlet to be freely movable, and forms a second air outlet which blows out taken-in indoor air. A control circuit blows out the indoor air from the second air outlet at a wind speed which is higher than the wind speed of cool air or warm air that is blown out of the first air outlet.Type: GrantFiled: December 27, 2013Date of Patent: March 10, 2020Assignee: FUJITSU GENERAL LIMITEDInventors: Syun Iwano, Tomofumi Kawai, Satoru Tokuda
