A chainsaw, comprising: a guide bar, a cutting chain and a driving unit arranged to drive the cutting chain around the guide bar. The guide bar defines a first longitudinal axis extending along a centre of the guide bar. The chainsaw further comprising a handle section for carrying and operating the chainsaw, wherein the handle section includes a control portion disposed on the upper side of the chainsaw. The control portion in turn includes a throttle lever for controlling the speed of the driving unit and the control portion has a left and a right side. The control portion defines a second longitudinal axis substantially extending along an upper side of at least a part of the control portion. An angle, A, between the first and the second longitudinal axes is between 14° and 45°.

This invention relates to an orthopaedic composition comprising porous chitosan particles suspended in a liquid medium wherein the liquid medium further comprises a biocompatible polymer. The invention also provides a process for preparing a solid or semi-solid orthopaedic material by drying the orthopaedic composition. The resulting solid or semi-solid orthopaedic material finds use as a bone-replacement material, a bone cement and a tissue scaffold. A process for preparing suitable porous chitosan particles for the present invention by incorporating a porogen capable of including crystallinity is also described.
摘要:
The invention discloses an electronics device for personal use, comprising at least a first main surface, and at least a first antenna for communication via electromagnetic waves between the device and a second party. The antenna is an array antenna comprising at least a first and a second antenna element, and is arranged on said first main surface. Suitably, the electronics device is a portable computer comprising a lid which may be opened or closed, said first main surface being the lid, so that the antenna is arranged in the lid of the portable computer.

A field controlled semiconductor device of SiC has a drain, a highly doped substrate layer on top of the drain and a low doped n-type drift layer on top of the substrate layer. A p-type base layer is located on the drift layer and a vertical trench extends through the base layer. In the trench an n-type channel region extends vertically along a wall of the trench and connects a source region layer to the drift layer. A gate electrode is arranged in the trench to be on the opposite side of the channel region with respect to the base layer.

Distributor device comprises at least one lower and/or one upper stationary distributor device for distribution of fuel in the form of gas and particles in a fluidized bed and is arranged above fuel feed nozzles in the bed, or at or above the upper limit of the bed. The task of the distributor device is to spread fuel, rising upwards in the bed, more evenly over a large area in the bed and to create turbulence above the bed. This is achieved by designing the distributor device with a mid-portion and upwardly-inclined wing-like members or the cone to bring about even distribution of fuel by forcing the fuel to follow an outwardly-directed horizontal or obliquely upwardly-rising flow of fuel.
