The image display device (100) provides images perceivable from the area of the eye box (E), and includes a light source unit (110), a screen (140), a scanning unit (130) and an optical system (155). The screen (140) has a single micro lens array (1) on which multiple micro lenses (3) are arranged. The scanning unit (130) includes a mirror (130a) to reflect beams emitted from the light source unit (110), and swings the mirror (130a) around a pivot center (130c) to scan the beams thereover, thereby generating images. The optical system (155) brings the images formed on the screen (140) to the eye box (E). An angle (θout) formed between a zero-order diffracted beam and a first-order diffracted beam, which are among a luminous flux of beams diffracted by the screen (140) and pass through the center of the eye box (E), is smaller than a minimum visual angle (Vmin).

The invention relates to dyeing devices, in particular to a leather level dyeing device. The leather level dyeing device has the technical effects of fast air-drying and level dyeing. In order to achieve the technical effects, the leather level dyeing device provided by the invention comprises a bottom plate, a dye box, a left support, a first support, a right support, a water pump, a first hard tube, a table top, a hard sponge, a dipping box, a top plate, a left-right moving device and the like. The top of the bottom plate is provided with the dye box, the left support, the first support and the right support in sequence from left to right. The top of the left support and the top of the right support are connected with the table top. The first support is located on the rear portion of the table top. The top of the table top is provided with the hard sponge. The left side of the table top is connected with the dipping box. The leather level dyeing device achieves the effects of fast air-drying and level dyeing. Blades can be used for stirring dyeing agents in the dye box. A soft brush is used for painting dyeing agents onto leather back and forth, so that the leather is painted more uniformly.

Several genes encoding subunits of the neuronal nicotinic acetylcholine receptors have been cloned and regulatory elements involved in the transcription of the ∝:2 and ∝:7-subunit genes have been described. Yet, the detailed mechanisms governing the neuron-specific transcription and the spatio-temporal expression pattern of these genes remain largely uninvestigated. The β2-subunit is the most widely expressed neuronal nicotinic receptors subunit in the nervous system. We have studied the structural and regulatory properties of the 5′ sequence of this gene. A fragment of 1163 bp of upstream sequence is sufficient to drive the cell-specific transcription of a reporter gene in both transient transfection assays and in transgenic mice. Deletion analysis and site-directed mutagenesis of this promoter reveal two negative and one positive element. The positively acting sequence includes one functional E-box. One of the repressor elements is located in the transcribed region and is the NRSE / RE1 sequence already described in promoters of neuronal genes.
