Provided is a refrigeration device which can, independently of outside air temperature, ensure stable refrigeration performance when the high-pressure side has a supercritical pressure, and which can improve cost and the easiness of construction. A refrigeration device is provided with: a pressure regulating throttle means which is connected to a refrigerant circuit which is located downstream of a gas cooler and upstream of a main throttle means; a decompression tank which is connected to a refrigerant circuit which is located downstream of the pressure regulating throttle means and upstream of the main throttle means; a split heat exchanger which is provided in a refrigerant circuit which is located downstream of the decompression tank and upstream of the main throttle means; an auxiliary circuit which allows a refrigerant within the decompression tank to be sucked into the intermediate pressure section of a compressor after causing the refrigerant to flow to a first flow passage in the split heat exchanger through an auxiliary throttle means; and a main circuit which allows a refrigerant to flow out from the lower part of the decompression tank, causes the refrigerant to flow to a second flow passage in the split heat exchanger, subjects the refrigerant to heat exchange with a refrigerant flowing through the first flow passage, and then causes the refrigerant, having been subjected to heat exchange with the refrigerant flowing through the first flow passage, to flow into the main throttle means.

Diaphragm device of a lens includes a click mechanism with a locking portion disposed in one of a stationary tube and a diaphragm setting ring, the locking portion having an elastically supported locking element, and an entrapment body disposed on the other of the stationary tube and the diaphragm setting ring. The entrapment body having an entrapment surface wherein a plurality of entrapment portions are formed for catching the locking element pressed against the entrapment surface at one of a plurality of aperture numbers when the diaphragm setting ring is turned. A mode select mechanism for switching between a click mode wherein the locking element is pressed against the entrapment surface and a non-click mode wherein a click function is deactivated with the locking element and the entrapment surface separated from each other by altering the position of at least one of the locking portion and the entrapment body.

The invention provides a wire grid polarizer and a manufacturing method thereof. The wire grid polarizer comprises an absorbing layer and a metal wire grid, wherein the absorbing layer comprises a base plate, multiple first bulge parts arranged on the upper surface of the base plates at intervals, aluminium wires arranged on the surfaces of the first bulge parts, and silicon dioxide layers; the metal wire grid comprises flat layers, aluminium layers arranged on the flat layers, and second bulge parts arranged on the upper surfaces of the aluminium layers at intervals; the surfaces of the silicon dioxide layers are coated with the flat layers; the second bulge parts are adopted to etch the aluminium layers so as to form a grating structure. Compared with the prior art, the overlapped double-grating structure can improve the visual angle defects of the existing wire grid polarizer and also can eliminate the bad situation of dark state light leakage.

The present invention relates to a method for manufacturing a pad for a touch panel and to a pad for a touch panel manufactured by same, wherein the method comprises the steps of: preparing a pad, which includes a light-transmitting insulator layer made of an organic insulator or an inorganic insulator, a light-transmitting conductor coating layer formed at a top of the light-transmitting insulator layer, and a metal coating layer formed at a top of the light-transmitting conductor coating layer, for manufacturing a touch panel; etching, from the metal coating layer of the pad for manufacturing the touch panel, at least a portion of the metal coating layer corresponding to a window, while leaving a portion of the metal coating layer corresponding to a lead line unetched; and etching the etched pad for manufacturing the touch panel to form the lead line and a touch pattern.; Through such operations, residual defects, consisting of metal dots left due to defective etching of the metal coating layer, are removed from a window portion, which is required to be transparent without blemishes when the pad is coupled to a display device such as an LCD, and thus the manufacturing yield of the pad for a touch panel can be improved.

The invention provides an external part structure which can eliminate the poor condition when the external part structure is used with other parts. A part main body (41) of a front protection device (1) is made of transparent resin, a surface (42) is provided with a surface side coating layer (43) which has the same color as a front bumper (12) and is nonopaque. The back (51) of the part main body (41) is provided with a mark forming part (52), and the part except the mark forming part is provided with a back layer (53). The back layer (53) includes a back side coating layer (61) which is laminated on the back (51) of the part main body (41) and a shading layer (62) which is laminated on the back side coating layer (61). The back side coating layer (61) has the same color or tone as the surface side coating layer (43). The back of the front protection device (1) is provided with a light source unit (71) which illuminates the mark forming part (52).
