摘要:
An antenna having an antenna element bent in a predetermined shape. The antenna element has a plurality of line conductors that are arranged in parallel and are sandwiched by two insulation films. A method of making an antenna has the steps of: arranging in parallel a plurality of line conductors, each of which having a width of 0.04 mm or less, at intervals of 10 times or more the width of each of the line conductors; discharging continuously the plurality of line conductors such that visibility of the line conductors is reduced; and sandwiching continuously the discharged line conductors by planar transparent insulation films with a sticking or adhesion layer to have an antenna element.

A full-length cDNA encoding a human-derived G protein-coupled receptor protein is isolated by screening a human hippocampus library. Also, a rat-derived cDNA corresponding to the human-derived cDNA is isolated. Proteins encoded by these cDNAs have an activity of lowering intracellular cAMP concentration under stimulation with histamine. These proteins are usable as tools in screening ligands thereof or in screening candidate compounds for drugs capable of regulating signal transduction from the above proteins.

A safety needle assembly includes a hub having a proximal end for connection to a syringe and a distal end, a cannula provided with a lumen and having a proximal end connected to the distal end of the hub and a beveled distal end, and a collar formed separately from the hub and mounted on the hub in a rotationally fixed manner, with the collar including a sheath mounting portion. A removable protector is positioned over the cannula and covers the beveled distal end of the cannula. A sheath having an opening is pivotally connected to the sheath mounting portion of the collar and is positioned outside the protector when the protector is positioned over the cannula. The sheath is pivotally connected to the sheath mounting portion of the collar to be pivoted, after removal of the protector to expose the cannula, towards the cannula so that the cannula passes through the opening in the sheath and is covered by the sheath.

A safety needle assembly includes a cannula connected to a hub, and a protector positioned over and covering the cannula. The protector is provided with an opening and is axially movable between a covering position and an uncovering position. A sheath provided with a channel is pivotally mounted with respect to the hub and is positioned in an initial position in which the through opening in the protector is closed by the sheath. The sheath is adapted to be pivoted away from the cannula towards an intermediate position and is adapted to be pivoted back towards the cannula to a cannula covering position in which the cannula is located within the channel. An engaging part of the protector engages the sheath during movement of the protector from the covering position to the uncovering position to cause the sheath to automatically pivot away from the initial position.
摘要:
A developing device 3 has a cover member 14 for covering an upper part of a developing roller 11. A seal 16 at a front end of the cover member 14 is brought into contact with a peripheral surface of a photosensitive drum 1. When toner particles are accumulated in the vicinity of a front end of the seal 16, the toner particles adhere to the photosensitive drum1, so that an undesirable black strip appears. Therefore, a voltage in a range from a developing bias to a potential at which the photosensitive drum 1 is charged is applied to a cover plate 15 of the cover member 14. The seal 16 is at a high potential which is the same in polarity as the potential at which the photosensitive drum 1 is charged. Accordingly, no toner particles are accumulated at a front end of the seal 16, so that no black stripe appears.
