Abstract: An electric power tool of the present invention includes a motor used as a drive source housed in a dual-separated type housing and includes a bearing support member that covers the outer circumferential surface of a bearing of the motor and supports the bearing from outside in the radial direction, and is configured such that the bearing and one end of the bearing support member in the axial direction are inserted in a tool component disposed coaxially, and a protruding portion that is the other end of the bearing support member and axially protrudes from the tool component is supported by receiving portions of a pair of housing parts.

Abstract: The fixing device includes: a fixing member that includes a conductive layer capable of heating by electromagnetic induction; a magnetic field generating member that generates an alternate-current magnetic field intersecting with the conductive layer of the fixing member; plural magnetic path forming members that form a magnetic path of the alternate-current magnetic field generated by the magnetic field generating member; a support member that supports the magnetic field generating member; an elastic support member that is arranged between the magnetic field generating member and the plural magnetic path forming members so as to be in contact with the plural magnetic path forming members; and a pressing member that presses the plural magnetic path forming members toward the magnetic field generating member.

Abstract: The brewing vinegar produced by zymolysis and alcohol fermentation in the bean jam particle of sloppy legumes such as adzuki bean in paraellel, and subsequently its acetic acid fermentation and its manufacturing method. By this manufacturing method the alcohol fermentation in the product by zymolysis is performed immediately, which shows the effective prevention of corruption by pest bacteria. Brewing vinegar containing abundant polyphenol is produced by the acetic acid fermentation performed sequentially.

Abstract: It is an object of the invention to provide an effective technique for making compact power tool having an electric motor. A representative power tool may include a tool bit, housing and an electric motor. The electric motor is housed in the housing and drives the tool bit. The electric motor includes an output shaft, a commutator, an armature, brushes, brush holders, a brush holder base, a cooling fan and a cooling-fan facing surface. The cooling-fan facing surface is formed on the brush holder base. The cooling-fan facing surface faces the cooling fan and extends flat in the centrifugal direction to guide the discharged cooling air from the cooling fan in the centrifugal direction. Because the brush holder base not only secures the brush holder but also smoothly guides the cooling air by means of the cooling-fan facing surface, the size of the electric motor in the axial direction of the output shaft can be reduced.
