摘要:
An image display apparatus for displaying an image of an object on a screen by using a projector includes a three-dimensional image display unit having a plurality of screens overlaid but spaced apart from one another, each of the screens diffusing and reflecting part of the light incident thereon and transmitting the remainder of the light, and an image projection unit having a plurality of projectors, each of the projectors is assigned to the corresponding one of the screens and projects an image of the object on the screen. The image projection unit displays a three-dimensional image of the object in the three-dimensional image display unit by projecting on the screens the shapes of the object in sectioning positions corresponding to the positions of the screens.

A polyolefin resin composition comprising (A) an ethylene-based polyolefin having a density of 0.865 to 0.980 g/cm3 and MFR of 0.01 to 50 g/10 min, (B) a phosphorous compound, and (C) at least one heat stabilizer selected from the group consisting of a phenol-based heat stabilizer and a tocopherol-based heat stabilizer. The polyolefin resin composition has excellent heat resistance, moisture resistance and discoloration resistance, and also when used as a packaging material, does not impair the taste of contents to be packaged, such as flavor or odor, and therefore does not impair the taste of the contents.

The present invention relates to a heater unit for the automobile air conditioner. The heater unit comprises a sensor group consisting of a plurality of sensors, mode selecting means for selecting one from at least two D/F modes above-mentioned, and control means for obtaining "target blowout tempeature (Tm)" based on input data from said sensor group and for selecting one out of said two D/F modes in which the rate of air through said foot outlet is greater, in the case where ambient air temperature taken by said sensor group is lower than the specified point corresponding thereto. In virtue of this, it contributed to improving air heating performance with window clouding prevented, in accordance with in- and out-car conditions.

This reed for weaving is characterized in that a plurality of reed dents each having a hollow portion in a front edge section are arranged such that the hollow portions are communicated with each other so as to form guide grooves for the weft, the depths of the hollow portions of the reed dents located at least at one end portion are made larger than the depths of the hollow portions of the other reed dents, and that the nearer the central side in the weft insert direction, the smaller the depths of the hollow portions of the reed dents are made so as to become approximate to the depths of said hollow portions of the other reed dents, and further, areas including portions corresponding to the hollow portions in the rear edge section of the reed dents are projected backward.

A tack-in apparatus is provided wherein injection ports are arranged at upper and lower sides of a weft yarn path, respectively. The injection ports inject currents for folding back an end portion of a cut weft yarn into a warp yarn opening on the weft yarn path which the weft yarn passes by a beating operation. Air guides projecting toward the warp yarn opening are formed at circumferential portions of the injection ports between the weft yarn path and the injection ports. The surfaces of the air guides which are on the sides of the injection ports are inclined toward the weft yarn path at front end portions of the air guides. In order to tack in the weft yarn end, the injection air currents are directed to the central portion of the warp yarn opening. This enables the weft yarn end to be transferred reliably, the tack-in operation to be carried out reliably, and the turbulence of the warp yarn to be reduced.

Disclosed is a polyethylene resin composition for heavy-duty packaging bag, which has a specific MFR, a specific density and a specific melt tension and which comprises (I) a linear low-density polyethylene resin prepared from ethylene and an .alpha.-olefin of 4 or more carbon atoms and having a specific MFR, a specific molecular weight distribution and a density of 0.900 to 0.918 g/cm.sup.3, (II) a linear medium or high-density polyethylene resin having a density of 0.935 to 0.970 g/cm.sup.3 and (III) a high-pressure low-density polyethylene resin having a density of 0.915 to 0.924 g/cm.sup.3, in a specific ratio of components. Also disclosed is a polyethylene resin film prepared from said composition. The composition is able to provide a film which is excellent in low-temperature properties such as low-temperature drop-bag strength and can be advantageously used for a heavy-duty packaging bag even in a cold district of below-freezing temperature. The polyethylene resin film exerts the above-mentioned effects.
