An ink circulation system includes: an ink-jet head in which a shared ink flowing route is formed, an ink tank, a supply flowing route for supplying ink from the ink tank to the shared ink flowing route, a reflux flowing rout for refluxing the ink from the shared ink flowing route to the ink tank, and a differential pressure generating unit for generating a differential pressure in the ink tank. The differential pressure generating unit is equipped with an impeller placed inside the ink tank, and a drive unit placed outside the ink tank. Then, the drive unit operates to turn the impeller, by means of remote driving, for generating a differential pressure between a supply port of the supply flowing route and a reflux port of the reflux flowing route so as to circulate the ink through the ink flowing route.

A method for manufacturing a junction semiconductor device, having a step for forming a first high-resistance layer, a step for forming a channel-doped layer, a step for forming a second high-resistance layer, a step for forming a low-resistance layer of a first conductive type that acts as a source region, a step for performing partial etching to a midway depth of the second high-resistance layer and the low-resistance layer, a step for forming a gate region below the portion etched in the etching step, and a step for forming a protective film on the surface of the region between the gate region and the source region. A gate region is formed using relatively low energy ion implantation in the surface that has been etched in advance to a height that is between the lower surface of the source area and the upper surface of the channel-doped layer.

A method of manufacturing a laminated structure capable of being patterned into a favorable shape by preventing side etching is provided. After an adhesive layer made of ITO or the like, a reflective layer made of silver or an alloy including silver, and a barrier layer made of ITO or the like are laminated in order on a substrate with a planarizing layer which is a base layer in between, a mask is formed on the barrier layer, and the adhesive layer, the reflective layer and the barrier layer are etched at once by using the mask to form a laminated structure. As an etching gas, for example, a gas including methane (CH4) is preferable. The laminated structure is used as an anode, and an insulating film, an organic layer including a light-emitting layer and a common electrode as a cathode are laminated in order on the laminated structure so as to form an organic light-emitting device. The laminated structure can be used as a reflective electrode, a reflective film or wiring of a liquid crystal display.
