A level including an elongate hollow frame with two sidewalls and a topwall extending therebetween, a topnotch defined by the walls which have notch-defining edges including non-vertical surfaces, and a vial within the topnotch. A vial-mounting structure includes a vial-holding member and a locking member movably secured with respect to the vial-holding member. The vial-holding member is configured for resting on the non-vertical notch-edge surfaces. The locking member includes frame-engaging portions which press upwardly against a frame inner surface to pull the vial-holding member downwardly against the non-vertical notch-edge surfaces, thereby securing the vial-holding member to the frame. A method for securing a vial-mounting structure to the level by providing the vial-mounting structure, which includes the vial-holding member, and pulling the vial-holding member downwardly against the non-vertical notch-edge surfaces by a force from inside the frame, thereby securing the vial-holding member to the frame.

In a connection between a motor and a position detector that together constitute a motor actuator, a connection shaft of the position detector is engaged with an outer peripheral surface of a motor output shaft, and a shaft portion of the connection shaft is engaged with an inner peripheral surface of the motor output shaft. Furthermore, radial recesses are provided to be radially outwardly recessed from the inner peripheral surface of the motor output shaft, and one of radial recesses of the motor output shaft engages with a single radial projection of the shaft portion of the connection shaft. Thus, the motor output shaft and the connection shaft are non-rotatably connected with each other, readily accurately.

The invention discloses a structure and method for installing a perpendicularity sensor on an ultralong tubular pillar. The structure comprises a laser gradiograph, a coarse adjusting bolt assembly, a fine adjusting bolt assembly, a light target, an installing bottom plate, an adjusting plate and a right-angle bent plate, and the perpendicularity sensor and a laser transmitter are arranged in the laser gradiograph. The perpendicularity sensor can measure the included angle between a measuring datum line and a natural vertical line. The laser of the laser transmitter is parallel to the measuring datum line of the perpendicularity sensor. The position of the adjusting plate is adjusted through the coarse adjusting bolt assembly and the fine adjusting bolt assembly so that when the light target is installed on different datum lines, the position of the laser on the laser target cannot be changed, and the laser transmitted after the laser gradiograph is installed and fixed is parallel to the axis of the tubular pillar. The problem of installing and positioning of the perpendicularity sensor on the ultralong tubular pillar is solved, it is ensured that the laser transmitted by the laser gradiograph is parallel to the axis of the tubular pillar, the measuring precision of the laser gradiograph is guaranteed, and the perpendicularity adjusting construction of the tubular pillar is more convenient and accurate.

The present invention corrects sash sag in casement windows by implementing an adjustable hinge. The adjustable hinge includes a sash arm, a support arm, a retaining clip and an adjustment mechanism. The adjustment mechanism serves a twofold purpose. First, it allows one to adjust the hinge for sash sag, and it also secures the support arm to the track of the adjustment hinge. The adjustment mechanism includes a threaded support post and a threaded member. The threaded support post has a circumferential groove which is used to receive the arms of a retaining clip. The sash arm is mounted to the track of the adjustable hinge via a shoe block. The sash arm has a protrusion located on its bottom surface. The protrusion serves as a movement restrictor.
