Abstract: Sealability between a helmet and a shield is improved. The helmet includes a main hat body, a shield, and a seal member. The main hat body is substantially spherical and includes an aperture window that opens forward to provide a field of view to a wearer. The shield is connected to a pair of turning mechanisms protruding from two side faces of the main hat body, and is movable between a closed position at which the shield is located so as to close off the aperture window and an open position at which the shield is located so as to open the aperture window. When the shield is at the closed position, the seal member seals a gap between an upper edge of the shield and an upper edge of the aperture window of the main hat body from a vicinity of one of the turning mechanisms to a vicinity of another of the turning mechanisms. An upper end portion of the shield is inflected toward the main hat body at least at upper edges of left and right end portion vicinities of the seal member.

Abstract: A good fitting sensation of a lens unit is obtained by performing fine adjustment of the position and angle of the lens unit. A lens unit attachment mechanism includes a frame member supporting a pair of lenses, side frame members extending rearward of the lenses from left and right end portions of the frame member, an angle adjustment member coupled to the lens unit and having two rotation pivot points, and a position adjustment retention member retaining the angle adjustment member so as to allow extending and retracting. The lens unit attachment mechanism adjusts the position and angle of the lens unit flexibly.

Abstract: An aerodynamic control device includes a void opening. The void opening decreases a resistance of a turbulence generated by a component part located behind a center of a longitudinal width of a helmet and is formed so that one end is connected to the helmet and the other end protrudes backward from the helmet.

Abstract: Provided are an electrode manufacturing apparatus and a method of manufacturing an electrode in which an electrode capable of preventing the occurrence of an internal short circuit is manufactured. A current collector is passed through a coating position in a downward direction by a reference roll. Thereby, just after coating of a mixture is interrupted, a built-up mixture between the current collector and a coating outlet is pulled in a downward direction by the current collector, so the position of the built-up mixture is lower than the position of the coating outlet. Therefore, the adhesion of the mixture to the coating outlet can be prevented, and as a result, a non-forming region where no mixture is formed can be prevented from being coated with the mixture.

Abstract: A helmet in which a subsidiary cap portion hardly pivots forward about an axial support means thereof as a fulcrum to undesirably move upward accidentally when a comparatively large impact acts on the helmet. A subsidiary cap portion locking mechanism which locks the subsidiary cap portion at a lower position includes a lock pin on a main cap portion and a locking recess for a lock lever on the subsidiary cap portion.

Abstract: To provide a method of manufacturing a battery capable of providing an equal amount of electrolyte in each battery and of enhancing productivity and coating machines employed thereof. The sensor detects a boundary from the collector exposed region C of the belt-shaped positive electrode to the positive electrode mixture layer exposed region B, on the basis of the detection timing, the shutter is withdrawn to open the flowing path and the proportioning pomp is driven. Following this, when the sensor detected a boundary from the positive electrode mixture layer exposed region B to a collector exposed region C, and on the basis of the detection timing, the shutter is protruded inside the flowing path to close the flowing path and the proportioning pump stops. As a result of this, the electrolyte stops to be delivered from the nozzle. The electrolyte layers are intermittently formed by repeating the same procedures.
