Abstract: A friction material for dry brakes containing, as raw friction materials, a fiber substrate, a binder, an organic filler, and an inorganic filler, wherein porous silica including a plurality of pores with a central pore diameter of 1.0 nm or greater and 50.0 nm or smaller that absorbs liquid matter generated by thermal decomposition of an organic matter in the friction material at the time of brake braking is contained as the inorganic filler.

Abstract: A toner image is formed on a first sheet surface and then heated. A conveyance unit includes a first rotary member configured to contact the first sheet surface and a second rotary member configured to contact a second sheet surface opposite to the first sheet surface. A conveyance guide is provided with an opening through which air is blown to the first sheet surface. The conveyance guide includes a first surface part and a second surface part. The first surface part is disposed on a location in a width direction overlapping with a location in the width direction of the first rotary member. In at least a part of a range between the opening and the first rotary member in the sheet conveyance direction, the first surface part is protruded with respect to the second surface part in a height direction.

Abstract: An impact driver includes a hammer that is rotated by a motor and an anvil configured to be struck by the hammer to rotate the anvil about a rotational axis. A hammer case houses the hammer. Two or more bearings are provided inside the hammer case and support the anvil. To inhibit vibration of the anvil during operation, the bearings may be differing types, such as a regular ball bearing and an angular contact ball bearing, and/or the bearings may have different inner and/or outer diameters. A contact member, such as an O-ring, may be disposed in an insertion hole of the anvil to reduce vibrations that are transmitted to the tool bit.

Abstract: A method for producing an L-amino acid such as L-lysine is provided. An L-amino acid is produced by culturing a bacterium having an L-amino acid-producing ability, which has been modified so that the activity of a carotenoid biosynthesis enzyme is increased, in a medium, and collecting the L-amino acid from the medium.

Abstract: An image forming apparatus comprises a light-emission unit, a reflecting member, a light-receiving unit, a detection unit, a ventilation unit configured to send air to the reflecting member; and a control unit. The control unit adjusts at least one of an operation duration and an airflow rate of the ventilation unit, in accordance with a detection signal outputted by the light-receiving unit when a sheet is not at a position where light crosses a conveyance path.

Abstract: A jigsaw includes a main body having a grasping part configured to be grasped by a user, a blade projecting downwardly from a front part of the main body and configured to reciprocate up and down, and a base coupled to a lower part of the main body and configured to make contact with a workpiece. A rear end of a contact surface that is configured to make contact with the workpiece is located at a position that coincides with or is rearward of the rear end of the grasping part.

Abstract: An image forming apparatus and a lock mechanism including a toggle mechanism capable of eliminating the problem of abnormal noise before and after a lock member passes a neutral point are provided. A lock mechanism includes a toggle spring that rotationally biases a toggle lever toward a standby position when the lever is between a standby position and a neutral point, and implements switching in a direction of the rotational biasing toward a locking position after the lever passes the neutral point. A projection and a locked portion of an engagement member are sandwiched by a toggle base and the toggle lever to maintain a contact state before and after the toggle lever passes the neutral point.

Abstract: A power tool, for example, a portable circular saw, includes a fan, a motor configured to rotate the fan, an output part or shaft driven by the motor, a motor housing that houses the motor, a grip housing connected to the motor housing, a trigger associated with the grip housing, and a brake member configured to brake a rotation of the motor, the brake member being mounted inside the grip housing. The brake member may be a resistive element of a rheostatic braking system. The housing and fan are configured such that cooling air is directed to cool the brake member.

Abstract: A three-dimensional modeling apparatus 10, 11 includes a three-dimensional modeling unit 20, 40 and a control unit 15. The three-dimensional modeling unit 20, 40 is configured to stack unit layers ul made of a material solidified in a predetermined solidification pattern thereby to produce a three-dimensional object O. The control unit 15 is configured to correct a sectional pattern sp at each level in a model M along a lamination direction, allowing for deformation in modeling based on at least one of a material characteristic, a modeling condition, and a facility condition, thereby to determine the solidification pattern corresponding to the sectional pattern sp.

Abstract: A jigsaw includes a motor, a rod having a blade attached thereto, a power transmission portion that converts rotation transmitted from the motor to vertical movement of the rod to vertically move the blade, and a counterweight that moves vertically in a direction of the vertical movement of the rod outside a range of the vertical, movement of the rod and the blade. At least a part of the counterweight is disposed so as to cross an extended line of a trajectory of the vertical movement of the rod. The counterweight moves vertically independently of the vertical movement of the rod which is produced by the power transmission portion.

Abstract: According to an aspect, a device includes: a display unit for displaying a screen; a sensor for detecting an inclination of the display unit; an operating unit for detecting an operation; and a controller. The controller changes an orientation of the screen depending upon the inclination detected through the sensor and the operation detected through the operation unit.
