In order to construct a brushless electric motor comprising a housing, comprising a rotor and comprising a stator, each stator unit including pole shoes, formed as claw poles, as well as a coil positioned following the rotor in the direction of the rotor axis, by means of which the pole shoes can be magnetized, at the lowest possible cost and as simply as possible, it is proposed that the stator unit has two pole shoe elements of which a first pole shoe element has a first pole shoe carrier as well as first pole shoes formed integrally onto this carrier and of which a second pole shoe element has a second pole shoe carrier as well as the second pole shoes formed integrally onto this carrier and that a bearing support made of plastics is molded onto the second pole shoe carrier of the stator unit and is thereby secured to it.

Disclosed is a closure arrangement for a can of the type which comprises a tubular body (10) having an open upper end (13) provided with a seat (16); and a plastic lid (20) comprising a sealing portion (21) and an axially breakable seal (25) formed by a lower skirt (25a) to be seated around the upper end (13) of the tubular body (10), and an upper edge (25b) internally incorporated to the sealing portion (21) by means of breakable radial bridges (26). The upper end (13) of the tubular body (10) presents a cross section contour that is substantially smaller than the largest cross section contour of the remainder of the tubular body (10), so that the contour of the lid (20) is maintained internal to said largest cross section contour of the tubular body (10), avoiding the mutual contact of the lids (20) of two adjacent cans disposed side by side.

A truck mounted attenuator (TMA) is constructed to minimize length during use in a horizontal position and height in a vertical transport position, as well as to minimize wind resistance and buffeting at highway speeds. A modular construction is employed, so that only damaged portions of the TMA can be removed and replaced in the field after a vehicle impact. The TMA comprises a plurality of outwardly curved tubular structural members which are designed to buckle upon application to the TMA of forces resulting from vehicular impact. The rigid tubes buckle at a high initial force, then proceed to crush at a lower force once the sides have buckled outwardly sufficiently to protect vehicle occupants during the critical first two feet of travel after impact. This design also provides increased protection for errant vehicles which impact the TMA device from an angle (i.e. “coffin corner” impact).

An earplug has an earplug body (12) with a front sealing portion (20) that seals to a person's ear canal, a body rear portion (22) that lies out of the ear canal, and a passage (26) that extends along the body axis and that allows environmental sound to flow into the ear canal when the passage is not blocked. The body rear portion has a lateral slot (30), and the earplug includes a blocking element (14) that is laterally (L) slidable along the slot. The blocking element can slide between a first position (14A) wherein a hole (32) in the element is not aligned with the passage to prevent sound from reaching the ear canal, and a second position (14B) wherein the hole is aligned with the passage to allow sound to reach the passage.

A security gate comprises a pair of posts fixed adjacent opposing sides of a gate opening. The gate includes a pair of first gate panels pivotally mounted on the posts and second gate panels pivotally coupled to the outer ends of the first gate panels respectively so that the second gate panels meet one another in the closed position of the gate. Each first gate panel and the respective second gate panel pivotally coupled thereto are moveable together between an open position folded adjacent the respective post and a closed position spanning across the gate opening. A drive linkage is coupled between each post and the inner end of the respective first gate panel pivotally coupled thereto to drive pivotal movement of the first gate panel between the open and closed position. A guide mechanism is coupled between the fixed post and the inner end of the second gate panel for guiding pivotal movement of the second gate panel between the open and closed positions responsive to movement of the first gate panel.

A digital microfluidics system manipulates samples in liquid droplets within disposable cartridges and has disposable cartridges each with a bottom layer, a top layer and a gap therebetween. A base unit with cartridge accommodation sites and at least one electrode array with electrodes works with a cover plate at the sites and a control unit for controlling selection of the electrodes and for providing them with voltage pulses for manipulating liquid droplets within the cartridges by electrowetting. The cover plate has an electrically conductive material that extends parallel to the array. A selection of disposable cartridges and a method for manipulating samples in liquid droplets that adhere to a hydrophobic surface can be used with the system.

A substrate adsorption device 1 includes: a stage 11 having an adsorption face 12 for holding a substrate 20; a plurality of adsorption ports 13 formed in a region of the adsorption face 12 of the stage 11; and a vacuum pump 14 connected to each adsorption port through an air discharge path 17. A pressure sensor 18 for detecting the pressure in the air discharge path 17 is provided, and a plurality of leak trenches 30 open to both the adsorption face 12 of the stage 11 and a side face of the stage 11 are formed in a region of the stage 11 except the region where the adsorption ports 13 are formed. With such a low-cost and simple structure, a foreign matter 15, which is a factor of inviting damage to the substrate 20, is detected, to prevent damage to the substrate 20.

An optical transmitting and/or receiving arrangement including an optical element mounted in an intermediate space between a base plate and a lens. The lens is supported by a structure that is mounted on the base plate, and a carrier element mounted on the base plate and has an end portion extending through an opening formed in the structure and into the intermediate space. The end portion of the carrier element is positioned adjacent to the optical element, and includes electrical feed lines that are connected to the optical element by wires or bands. A transparent casting compound is then injected through the opening into the intermediate space.

In a fitting confirmation construction, a lock arm is provided in a housing of a first connector. The lock arm includes a lock wall inclined and disposed at a front end of the lock arm in a direction from the first connector toward the second connector; a deflection space formed at a rear of the lock wall in the direction; and an operation plate disposed on the deflection space. A confirmation opening is provided in a rear wall of the housing, and has a height equal to a height of the deflection space. A lock projection is provided on a second connector to be brought into engagement with the lock wall. A rear end face of the operation plate is exposed to a rear outside of the housing of the first connector through the confirmation opening, only in a state where the lock arm is deflected.
