Abstract: An electric power tool disclosed herein may include a motor; a power transmission mechanism connected to the motor; a housing that houses the motor and the power transmission mechanism; a tip tool holder connected to the power transmission mechanism; a cover covering the tip tool holder partially; a first locking mechanism configured to switch between a first locking state and a first unlocked state; and a second locking mechanism configured to switch between a second locking state and a second unlocked state. In the electric power tool, the cover may become detachable from the housing when the user performs the second unlocking operation on the second locking mechanism and the first unlocking operation on the first locking mechanism.

Abstract: A hand-held tool, such as a disc grinder, is used to perform work at a high work site, a countermeasure is taken to prevent the hand-held tool from falling by using a suspension tool, such as a tether strap. If a coupling part that couples the suspension tool to the hand-held tool is damaged, this fact is notified to a user. Thereby, an original function of the suspension tool can be reliably performed. If a large impact is applied to a coupling member via a suspension tool, the coupling member is displaced to a second position, due to the deformation of a first position retaining member. A conductive portion disengages from contacts to cause a power circuit to be shut off, thereby prohibiting a main body part from being activated.

Abstract: Provided is a multilayer heat-insulating material which reduces a deterioration in heat-insulating performance at the periphery of a mounting means for mounting on a mounting subject and which facilitates deformation into a desired shape. This multilayer heat-insulating material comprises a heat-insulating member (2) in which heat-insulating sheets (2a) and spacers (2b) are laminated, an engagement sheet (3) provided adjacent to the heat-insulating member (2), heat-insulating member engagement fixtures (5) for penetrating through and engaging the heat-insulating member (2) and the engagement sheet (3), and a mounting member (4) that is provided on the engagement sheet (3) and that can be removably attached to a mounting subject (9). Engagement of the heat-insulating member engagement fixtures (5) is such that the layers of the heat-insulating member (2) do not adhere to each other.

Abstract: A first current cut-off unit that cuts off a current input from a power-supply-voltage input terminal connected to an AC power source when a current value of the current exceeds a preset threshold, and a second current cut-off unit that cuts off a current output from the first current cut-off unit when a voltage value of a voltage applied from the power-supply-voltage input terminal exceeds a preset threshold are configured. A current cut-off element provided on a current path from the power-supply-voltage input terminal toward a DC output terminal, and a resistor that draws a current having passed through the current cut-off element toward a ground are provided as the first current cut-off unit.

Abstract: The BCA recording and reproducing apparatus performs recording of data onto an optical disc placed on a recording turntable, reproduction of data recorded on an optical disc placed on a reproducing turntable and ejection of an optical disc placed on an exchanging table and placement of a new optical disc on the exchanging table in parallel. A processing time is thereby shortened compared with the case of performing data recording, reproduction and exchange in series.
