A slotted pin tool, a delivery system containing the pin tool, a substrate for use in the system and methods using the pin tool and system are provided. The slotted pin tool contains a plurality of pins having slotted ends designed to fit around each loci of material deposited on a surface, such as a microarray, without contacting any of the deposited material. Sample is delivered by contacting the pin tool with the surface; the amount delivered is proportional to the velocity of the pin tool as it contacts the surface or the velocity of the liquid when movement of the pin is halted.

A semiconducting gas sensor includes a gas-sensitive layer, a heater for heating the layer to a defined measuring temperature, and contact electrodes for measuring the electrical resistance of the gas-sensitive layer enclosed within a microchamber, in which the gas-sensitive layer is arranged. The chamber can be sealed from the outside, and is constructed so that the chamber volume is small enough to allow at least one component of the gas or gas mixture that is to be analyzed to be at least largely exhausted via conversion on the gas-sensitive layer, within a predetermined measuring interval. With the limited gas store and the conversion of a component of the gas during the measurement process, gases or gas mixtures comprising several components can be analyzed. In this, the measuring signal is reexamined following the conversion of at least one component. Within the chamber, several sensor elements may be arranged with gas-sensitive layers, and may be operated at different temperatures. One gas sensor system, for example, is comprised of at least two semiconducting gas sensors having microchambers, which are arranged within a system of gas lines and valves, and can be filled individually.

A UV curing system includes a light source, which produces UV light and non-useful light (heat energy), a shade member having a lamp-side surface that reflects light and provides thermal insulation to the target substance, and a housing having an internal reflecting surface. The shade member is situated between the light source and the target substance so that all, or most, light from the light source does not directly strike the target substance. The housing is situated on the opposite side of the light source from the barrier and partially encloses the light source. The shape of the internal reflecting surface of the housing, the shape of the shade member, and the location of the internal reflecting surface of the housing, the shade member and the light source with respect to each other are selected so that at least some of the UV light emitted by the light source is reflected onto the target substance after striking the shade member and/or the internal reflecting surface of the housing and non-useful light emitted by the light source is attenuated (by path length increase, physical blockage, insulating properties of the shade member and/or dichroic filter action) thereby keeping the target substance cooler during a curing process than it would otherwise have been without the presence of the shade member.
摘要:
A coaxial drive shaft system is provided with an overload shearable coupling for driving multiple outputs from a single input. A pair of coaxial, telescoped drive shafts are provided as independent outputs to a pair of driven devices. A singular input shaft is coupled to the drive shafts by a gearbox for simultaneously rotating the drive shafts. A shear section is formed in one of the drive shafts for rupturing the one drive shaft in response to an overload condition thereon, while the other coaxial, telescoped drive shaft continues to be rotated by the singular input shaft.
摘要:
A method for operating a valve actuated with the aid of an actuator, in particular, an injection valve of an internal combustion engine of a motor vehicle, where the actuator is activated using an activation signal characterizing a desired opening duration of the valve. The activation signal characterizing the desired opening duration is corrected as a function of a valve delay time, in order to obtain a corrected activation signal for activating the actuator; the valve delay time representing a temporal deviation between the activation signal and an actual change of an operating state of at least one component of the valve, in particular, of the valve element of an electromagnetic actuator, or of a valve needle.

The invention relates to a hoop lock for two wheelers, wherein the hoop lock has a lock body and a substantially U-shaped hoop. The hoop is selectively releasable from the lock body or latchable to the lock body. The hoop has at least two wire sections which extend along the U-shape of the hoop alongside one another, and which are surrounded, at least regionally, by a sleeve.

The invention relates to a cylinder lock of the type of a disk tumbler cylinder having a cylinder housing and a cylinder core rotatable therein, with a plurality of blockable disk tumblers being provided in the cylinder core which have at least one respective engagement section. The disk tumblers are movable between an unlatched position and a latched position and are biased along a respective direction of bias into the latched position. In the latched position, the respective engagement section engages into an associated cut-out in the cylinder housing to block the cylinder core against a rotary movement relative to the cylinder housing. The cylinder core is rotatable in a rotary opening direction relative to the cylinder housing when the disk tumblers are in the unlatched position. At least one of the disk tumblers has a toothed zone which can be brought into engagement with a counter-toothed zone of the cylinder lock such that the disk tumbler is blocked against a movement opposite to the respective direction of bias when the disk tumbler is in the latched position and a torque is exerted onto the cylinder core in the rotary opening direction.
摘要:
A fuel injection system having a high-pressure side which includes at least one high-pressure reservoir, in which fuel is stored at injection pressure, and at least one injector communicating with the high-pressure reservoir for fuel injection at a cylinder of the engine. The fuel injection system moreover has a low-pressure side which communicates at least indirectly with a fuel tank. The high-pressure side has a communication with the low-pressure side, which communication is controlled as a function of the fuel temperature in the high-pressure side and at a high fuel temperature is at least substantially closed, so that the high-pressure side is disconnected from the low-pressure side, and that is open at a low fuel temperature.
