In one embodiment, an air guiding plate is attached to an enclosure with a plurality of vents defined therein. The air guiding plate includes a plurality of guiding holes defined therein. Each of the guiding holes is surrounded by a plurality of walls and includes an inlet with a large size, and an outlet with a small size. The outlets are in alignment with the vents of the enclosure. A size in cross section of each of the walls gradually decreases along a direction from the inlet to the outlet.

The invention relates to a device for partitioning the plastic parisons to give at least one semifinished open-surface product (6), where the device encompasses at least one means of partitioning (3) the plastic parison and one means of drive (2). The means of drive may be composed of one, but preferably of two, driven rolls. It has been found that use of the device of the invention can reduce or prevent the production of creasing and irregularity at the margins, i.e. at the cut edges, of the pa...

A synchronous spacer with a guiding block comprises strip-shaped links, a plurality of spacer elements, and a guiding block fixed at the end of the links. An arch-shaped surface is formed on the guiding block and is located correspondingly to inner surface of the track of the linear guideway, the guiding block is larger than spacer element of the synchronous spacer but is smaller than the rolling elements. With the guidance of the guiding block, the synchronous spacer is prevented from impacting...

The invention relates to a method of determining the position of a catheter introduced along a guide wire inserted into a body, in which method an image of the guide wire and the body region at the area of the guide wire is acquired by means of an imaging method, the distance traveled by the catheter on the guide wire is measured and the position of the catheter in the body is determined on the basis of the measured distance. The invention also relates to a device for determining the position of...

A light-guiding structure includes a light-guiding plate, and an LED set matched with the light-guiding plate. The characteristic is that the light-guiding plate has a light-entering surface, and there are a plurality of ditches on the light-entering surface. A light-entering interface is formed between two adjacent ditches. The LED set corresponds to the light-entering surface of the light-guiding plate, and each of the LEDs of the LED set corresponds to one light-entering interface. By utilizi...

Optical devices for guiding illumination are provided each having a body of optical material with staircase or acutely angled ramp structures on its top surface for distributing light inputted from one end of the device from the front exit faces of such structures along certain angular orientations, while at least a substantial portion of the light is totally internally reflected within the body until distributed from such front exit faces. Optical devices are also provided each have a body of o...

A material-guiding device in a mower-conditioner surrounds an upper front region of a crop processing rotor and is composed of an upstream-situated portion and a downstream-situated portion. The downstream-situated portion is adjustable relative to the upstream situated portion and is connected thereto such that the adjustment of the upstream-situated portion simultaneously leads to an adjustment of the downstream-situated portion, such that an adjustable angle .alpha. present between the two po...

A guiding assembly is described for guiding a manually controlled cutting tool relative to a lathe axis. The guiding assembly includes a longitudinally extending tool rest (12) which can be fixed to a lathe by mounting spigots (17,18) and which is fixed to a longitudinally extending guide (13) along which a cutting tool mount (42) can freely slide. The cutting tool (27) slides freely within the mount (42). A follower (29) is attachable to the cutting tool to follow a template (16) mounted on the...

A destination navigation method is disclosed, which includes locating present position and destination, searching route to the destination. The method includes giving driving guidance along a route set on basis of a predetermined evaluation index or selection of driver and further determining whether searched route contains a short distance lane change section, where a road having many lanes and distance between an entryway to the road having many lanes and a junction (exit way) is short in orde...
