Abstract: There is provided a helmet with an improved cradling function and fitting comfort, while also making the helmet easier to put on or take off. The invention comprises an attaching member and a cushion member. The attaching member has a base member mounted in contact with a shell, and a form-maintaining member disposed at an inner lower section of the base member, there being a space left with respect to the base member. The form-maintaining member, while simultaneously keeping a surface corresponding to the cushion member in a profile following the cheek to the chin portion of a wearer, causes the space to contract as a result of being outwardly displaced in the thickness direction in response to greater-than-normal force applied when a helmet is put on and taken off; and, following the displacement that causes the space to contract, is restored so as to return to an original location under normal circumstances, and kept there.

Abstract: A display apparatus is capable of performing a gradation display and a high-speed low-power-consumption display by controlling the colored state of each pixel to an appropriate state. A driving method for the display apparatus displays images through deposition and dissolution of a metal by impressing a predetermined voltage on each pixel. A voltage pulse or AC voltage having an amplitude of not more than a threshold for deposition of the metal is impressed, and a writing pulse or an erasing pulse is controlled according to the resultant current. Alternatively, an additional writing pulse is impressed when the current is lowered to or below a predetermined value, after the writing. Further, the state of the pixel is detected through the current, and a rewriting operation is selected according to the detected state.

Abstract: A lens layout block device comprising a seal feeding device that supplies an elastic seal to a seal sticking position (A5). The elastic seal is loaded in a tape loading part in the form of a seal tape covered by a mount and a protective sheet and wound in a roll shape and fed by driving a motor. The protective sheet is separated by a protective sheet separating mechanism. At the seal sticking position (A5), a sensor detects the leading edge of a positioning hole in the mount and stops the conveyance of the seal tape after the seal tape is fed from the detection position for a specified time. The stop position is determined as the reference sticking position of the elastic seal and a lens holder is pressed against the elastic seal from above. The mount is pulled down by the seal separating mechanism to separate the mount from the elastic seal.
