Patent number: 11256282Abstract: A control lever device of an industrial vehicle includes a control lever that is tiltable forward and rearward relative to a vehicle body of the industrial vehicle and that includes a control knob, a switch button that is provided on the control knob and adapted to be pushable while the control lever is operated. The switch button has a movement axis indicating a movable direction of the switch button. The movement axis is inclined forward relative to a direction orthogonal to an extending direction of the control knob so that a pushing direction of the switch button is directed rearward from the direction orthogonal to the extending direction of the control knob.Type: GrantFiled: June 26, 2020Date of Patent: February 22, 2022Assignee: KABUSHIKI KAISHA TOYOTA JIDOSHOKKIInventors: Kenichiro Kawaguchi, Hideki Nakashima, Kazushi Kamiya, Nobuaki Kawabata

Patent number: 5049186Abstract: Water-based compositions of the water-based wax emulsion type for protecting coating films are provided by emulsifying and dispersing, as essential components, [A] a disperse phase component and [B] an emulsifier component in water. The disperse phase component [A] is formed of (a) a petroleum fraction wax having a melting point of 50.degree.-90.degree. C., (b) an oxygen-containing wax having an oxygen content of at least 3.0 wt. % and a melting point of 50.degree.-85.degree. C., (c) an ethylene/.alpha.-olefin copolymer having a number average molecular weight of 2,000-20,000, and (d) a higher fatty acid metal salt and/or a metal-modified hard wax. The compositions can form, without the need for a solvent, strong barrier coats which are resistant to rain, moisture, sunlight and air pollutants even under severe environmental conditions. After these barrier coats are used, they can be easily removed with warm water containing a small amount of a solvent or steam.Type: GrantFiled: March 16, 1990Date of Patent: September 17, 1991Assignee: Nippon Oil Co., Ltd.Inventor: Nobuaki Kawabata
