A surgical instrument may comprise a chassis, a shaft coupled to the chassis at the proximal end of the shaft, an end effector coupled to the shaft at the distal end of the shaft, a force transmission mechanism coupled to the chassis, and an actuation element connected between a lever arm of the force transmission mechanism and the end effector. The force transmission mechanism includes a worm drive, and the lever arm comprising a first end and a follower member at the first end of the lever arm, wherein the follower member is engaged with the worm drive and is configured to be driven by the worm drive. Rotational movement of the worm drive imparts translational movement to the actuation element via the lever arm, and the lever arm slides along a generally linear direction relative to the chassis to impart the translational movement to the actuation element.

Drive of a seat adjusting device, especially for motor vehicles, with a spindle that is fastened on a first of two rails, which are adjustable with respect to each other, by means of at least one mounting located at the end of the spindle and with a transmission driven by a motor that is mounted on the second rail, whereby the mounting has one part as a base plate, from which two walls at a distance from each other extend upward and that at least one end of the spindle is fastened between these two walls.

A mechanism 21 for converting rotating motion to rotating and reciprocating motion and/or vice versa. The mechanism has a housing or support 22, a first member 23 rotatable about a first axis and reciprocable along the first axis, and a second member 2 rotatable about a second axis spaced from the first axis. Rotation of the first member 23 or the second member 25 causes rotation of the other member. A guide 29a, 29b is configured to contact a cam surface 27a, 27b. The cam surface or the guide is provided on the first member 23. The cam and guide are configured to cause the first member 23 to rotate upon movement of the first member along the first axis, or to move along the first axis upon rotation of the first member 23.

Surveillance networks are used to observe large areas, like public places, streets, public buildings or private houses, privates premises etc. The surveillance networks often comprise a plurality of surveillance cameras. Such surveillance cameras should be small, robust, trouble-free and have low-maintenance requirements. Subject-matter of the invention is a linear actuator (8) for a linear motion of a component of a camera (1), the linear actuator comprising a supporting structure (6), a motor (10) arranged on the supporting structure for generating a rotational movement, a component carrier (7) for carrying the component and for performing the linear motion relative to the supporting structure, a gear mechanism (11) for transmitting the rotational movement, whereby the last gear of the gear mechanism before the component carrier is a transfer gear (20), whereby the transfer gear comprises a guide way (23a, b, c) extending in rotational direction of the transfer gear with a slope along the guide way whereby the component carrier is coupled with the guide way by resting means (24a, b, c), so that the component carrier is displaced in the linear direction (9) by a rotational movement of the transfer gear due to the slope of the guide way.

A handle arrangement includes a handle transitionable between an undrawn configuration and a drawn configuration. A handle lever can be coupled to a rotational member and configured to rotate the rotational member as the handle is transitioned to the drawn configuration. The rotational member can be configured to actuate a cam lever. The cam lever can be configured to actuate a latch cam between a first position corresponding to the undrawn configuration of the handle and a second position corresponding to the drawn configuration of the handle. The latch cam can be configured such that transitioning the handle between the undrawn configuration and the drawn configuration causes the latch cam to transition from the first position to the second position. The latch cam can initially move in a direction away from the second position before arriving at the second position.

A robot includes a base; a trunk linked to the base; a multi-joint robot arm rotatably linked to the trunk; and an elevating mechanism capable of bringing the trunk to a low position and a high position higher than the low position, and a time taken when a tip of the multi-joint robot arm is moved by a predetermined distance when the trunk is at the high position is longer than a time taken when the tip of the multi-joint robot arm is moved by a predetermined distance when the trunk is at the low position.

A device for securing a support element to an actuating lever of a valvetrain of an internal combustion. The actuating lever having a socket dome to accept a socket end of the support element and a roller pocket, with the securing device seated on the socket dome, extending through the roller pocket and splitting into two arms that extend on opposite ends of a circumferential groove below the socket end of the support element.
