Abstract: A method for manufacturing a light-emitting element includes exposing a portion of an insulating layer from under a metal layer and a semiconductor layer by removing, through an opening of a resist layer, a portion of the metal layer and a portion of the semiconductor layer by wet etching using a first etchant, etching rates of the first etchant for the metal layer and the semiconductor layer each being higher than an etching rate of the first etchant for the insulating layer; removing the resist layer by wet etching after the removing of the metal layer portion and the semiconductor layer portion; and after the removing of the resist layer, removing a remaining portion of the metal layer while causing the insulating layer exposed from under the metal layer and the semiconductor layer to remain. The opening of the resist layer is positioned directly on the conductive layer.

Abstract: A towing tractor includes a tractor body, a motor, a controller, a cable electrically connecting the motor and the controller, an axle housing integrally mounted with the motor, and a suspension through which the axle housing is supported by the tractor body. The controller is fixed to the tractor body. The length of the cable is greater than the shortest distance between the motor and the controller. The suspension allows vertical movement of the axle housing and the motor relative to the tractor body. The controller, the axle housing and the motor are arranged in this order in longitudinal direction of the tractor body. The controller is located above the axle housing and the motor. The cable led out from the motor extends below the axle housing and then upward toward the controller. The part of the cable between the axle housing and the controller forms an extra length portion.

Abstract: The present invention relates to an automotive interior member placed on a part that receives sunlight (R) entering through a window (2) of an automobile (1). A corrugated sunlight-receiving surface (6) receives the sunlight (R). The corrugated sunlight-receiving surface (6) comprises a first slope (8), which receives the sunlight (R) entering through the window (2), and a second slope (9), which is disposed on a part where the sunlight (R) is blocked by the first slope (8), i.e., which faces the inside of an automotive compartment (1a). A cooling air passage (10) that extends along the underside of the sunlight-receiving surface (6) is provided in the interior member, and a blowing means (13) is provided in an air duct (12) that communicates with the cooling air passage (10).

Abstract: The safety of a load carrying device has been enhanced by providing interactive mechanisms to ascertain the operations in predetermined manner. The enhanced safety mechanisms interactively force the operator to ascertain safety while an object such as a battery is loaded onto or unloaded from a predetermined structure such an industrial vehicle. The carrying device is engaged with the industrial vehicle during the loading or unloading task. In addition, the object is locked during the transportation. These safety features are mechanically ascertained.

Abstract: A towing device for selectively locking a towing load has a support member that pivotably supports a link member at a first pivotal point near the first proximal end. A stopper is located on the support member for regulating a pivotal movement of the link member. A joint member is pivotably coupled to the link member near the first proximal end at a second pivotal point and has a tendency to pivot about the second pivotal point toward the first pivotal point to contact the stopper as the first proximal end pivots toward the stopper about the first pivotal point. A coupling member is connected to the second distal end of the joint member. An interference avoiding unit is located near the joint member for guiding the joint member to maintain a certain distance from the stopper as the link member pivots about the first pivotal point.

Abstract: A structure of a backrest assembly for a standing ride type driver's platform in an industrial vehicle which an operator drives and controls while standing, includes a backrest pad and a backrest height adjustment mechanism. The backrest pad is installed in the driver's platform, and includes a backrest portion for supporting the operator's back and a seat portion that protrudes forward from the backrest portion for supporting the operator's buttocks. The backrest pad is installed in the driver's platform through a backrest height adjustment mechanism.

Abstract: A battery holding mechanism in an industrial vehicle that has a vehicle body includes a battery compartment provided adjacent to a driver's platform for installing a battery for accommodation therein from an opening formed in a side surface of the vehicle body. Also, the battery holding mechanism includes a battery stopper and a stopper operating member. The battery stopper is located adjacent to the opening for blocking the opening to hold the battery in the battery compartment and for opening the opening to allow the battery to be taken out from the battery compartment. A stopper operating member moves in conjunction with the battery stopper when the battery stopper opens the opening, such that at least a part of the stopper operating member is exposed to the driver's platform.

Abstract: The object of the present teachings is to provide an improved battery-operated towing tractor. A representative towing tractor is operated by means of battery and the battery may be installed to and removed from the battery storage chamber of the towing tractor by using an opening disposed at the side surface of the battery storage chamber. Because the battery is installed and removed through the side surface of the battery storage chamber, the tractor surface can be effectively used.
