摘要:
The present invention relates to an ironing board cover with at least three layers (18, 20, 22) that are arranged on top of each other, wherein one of the layers (18, 20, 22) is a heat resistant cover layer (18) that is permeable to steam (26), another one of the layers (18, 20, 22) is a porous layer (20) that is at least partially permeable to steam (26) and heat, and a further one of the layers (18, 20, 22) is a water proof layer (22) that is impermeable to steam (26) and/or liquid, wherein the porous layer (20) is arranged between the cover layer (18) and the water proof layer (22).
摘要:
A showerhead that injects two process gases into the processing chamber via separate sets of holes. The showerhead is constructed of upper plate and lower plate. Upper plate has a first set of holes. The lower plate has two sets of holes: one set is aligned with the holes in the upper plate, while the second set has no corresponding holes in the upper plate. Both sets of holes in the lower plate are made to have two different diameters: a larger diameter extending from the top surface of the lower plate, while a smaller diameter extends from the bottom surface and meets with the larger diameter. A set of pipes are inserted through the holes in the upper plate and the corresponding holes in the lower plate, and are sealingly brazed to both plates. Cooling channels may be provided in the lower plate.

A steaming system (100) comprises a steam generator (120), a removable water tank (130) for holding and supplying water to the steam generator (120); and a dosing device (140) for supplying an amount of a water treatment agent to the water tank (130). The dosing device is configured to be triggered by a movement of the water tank (130) relative to the steam generator (120).
摘要:
A method and a device for reducing a signal peak value are adapted to solve a problem that overall performance of a system is significantly degraded caused by allocating a same weight to each sub-carrier so as to averagely distribute a peak clipping noise to each sub-carrier. The method includes: receiving a signal (21); and performing a peak clipping processing on the received signal by using a peak clipping signal (25). The peak clipping signal is formed according to a peak clipping weight factor and the received signal, or according to a frequency domain error vector magnitude (EVM) and the received signal. In the method, a weight of each sub-carrier is set according to the peak clipping weight factor or the frequency domain EVM during the peak clipping processing, thereby improving the overall performance of the system.
摘要:
A garment de-wrinkling device (1) comprises an enclosure (10) for moistening garments (20). An ironing board (40) and an adjacent standby area (41), which are both permeable to steam, are arranged on top of the enclosure (10). During operation of the device (1), the ironing board (40) and a steam iron (30) are used to iron garments (20) which have first been moistened inside the enclosure (10). In the process, steam released by the iron (30) penetrates the garments (20) and enters the enclosure (10) through the ironing board (40). In this way, both the garments (20) on the ironing board (40) and those inside the enclosure (10) are treated by means of steam that is released by the iron (30), and steam is used in an efficient manner. A pressed look is obtained in that the garments (20) are subjected to a moistening process and a subsequent steam ironing process.
