  • Patent number: 9159255
    Abstract: Provided is a device which can present three dimensional information by a simple structure and in which the information can be viewed with the naked eye. A plurality of rotary line-light-source units are arranged. The line-light-source units provide different pieces of image information in different directions, in order to produce a parallax between both eyes. A three-dimensional image control unit performs a control to provide thinned image information at corresponding positions to the plurality of line-light-source units and successively present the entire three-dimensional image information by scrolling. As a result, a viewer can recognize the three-dimensional image moved and presented by the scroll control.

  • Patent number: 8267070
    Abstract: High pressure regions (31H to 35H) and low pressure regions (31L to 34L) are created based on the exhaust gas flow at curves in an EGR pipe (30), thereby enabling the exhaust gas pressure at inlets (21b to 26b) of gas introduction passages (21a to 26a) to be adjusted. Accordingly, regardless of the number of cylinders or whether the lengths of the flow paths of the EGR pipe (30) are the same, the exhaust pressure at the inlets (21b to 26b) of the gas introduction passages (21a to 26a) can be appropriately adjusted so any difference in pressure of exhaust gas introduced into branch pipes (21 to 26) can be reduced. In this way, the EGR rates of the cylinders can be made closer or the same such that stable combustion can be achieved, thus enabling stable engine operation to be maintained. The EGR pipe (30) is arranged weaving closely between the branch pipes (21 to 26) so space efficiency can be improved and a sufficient amount of exhaust gas can be introduced evenly into the cylinders.
