A firearm magazine loader (30) comprises a body (32) coupled to a movable press (40), a plunger (20) extending out of the press towards the body, and a magazine aligner (52). The body is hollow and adapted to fit and slide over an open side of a magazine (10). A spring (48) is positioned between the body and the press to force them apart. To load the magazine, the user squeezes the press towards the body such that plunger is over a topmost round (12) in the magazine, and then presses down the loader, causing the plunger to force the topmost round further into the magazine to form a vacant space below lips (14) of the magazine. This enables a new round (13) to be rearwardly, case first, loaded inside the vacant space. The user then eases the down force on the loader allowing the spring (16) of the magazine to force up all the rounds in the magazine towards the lips while releasing the press for allowing the spring of the press to force the press and plunger back to their original position. The magazine aligner is positioned inside the body for centering the open side of magazines of different widths and depth mounted in the loader in line with the plunger.

A transport roller is provided in a transport path in order to transport paper, the transport roller transporting the paper downstream in the transport path by making contact with the paper, and At least one contact portion that makes contact with the paper is provided in the transport roller. The contact portion is deformable in a direction that releases pressing force received from the paper when transporting the paper.

The invention relates to a switch mechanism of an electric tool. The switch mechanism is arranged on a motor housing of the electric tool, and comprises a switch button, a sliding bar and a stop mechanism used for preventing the sliding bar from moving to the rear end of the motor housing, wherein the sliding bar is slidingly arranged in an inner side channel arranged on the motor housing, so that the sliding bar can be contacted with a trigger switch on a power supply line; the sliding bar tends to move to the rear end of the motor housing under the action of an elastic force to release pressing on the trigger switch; the switch button is mounted at the front end of the sliding bar in a pivoted manner; an elastic device is arranged between the switch button and the front end of the slender sliding bar; and the elastic device tends to allow the switch button to pivot around a longitudinal axis of the motor housing, so that one side part of the switch button is far away from the motor housing and the other side part of the switch button pushes against the motor housing. The invention further relates to the electric tool comprising the switch mechanism. According to the switch mechanism and the electric tool, a fatigue feeling of an operator can be alleviated, and the safety of the electric tool can be improved.

A method of transporting a semiconductor wafer having a ring-shaped stiffening portion can include the steps of pressing the semiconductor wafer from the back surface side to the front surface side thereof on a place different from a place at which the semiconductor wafer is to be held, the step of pressing the semiconductor wafer being conducted before holding the semiconductor wafer having the ring-shaped stiffening portion. The method can include releasing the attachment by suction of the front surface of the semiconductor wafer by supplying a positive pressure onto the chuck table, releasing pressing the semiconductor wafer from the back surface side to the front surface side thereof on the place different from the place at which the semiconductor wafer is to be held and picking up the semiconductor wafer having the ring-shaped stiffening portion from the chuck table while holding the semiconductor wafer.

A liquid cosmetic case includes a discharger (20) which discharges and seals liquid cosmetic by having a brush (30) at the upper side of a tube-shaped container (10), a supporting cap (50) and a cap (60) by forming a non-return valve (40) at one side of the upper part of the tube-shaped container (10). When used, if the tube-shaped container (10) is pressed, only a necessary amount of liquid cosmetic is discharged through the discharger (10) for easy use, and if the press is released by the non-return valve (40) formed at one side of the tube-shaped container (10), as the valve hole (41) formed at the non-return valve (40) is opened and closed, the air flows into the tube-shaped container (10) or the air is blocked, so that the contraction and the restoration of the tube-shaped container (10) can be done easily, making the repeated presses of the tube-shaped container (10) easy and the use of liquid cosmetic easy.
