Abstract: A reflective liquid crystal lighting device includes a light source, a tabular transparent light guide for receiving light emitted from the light source at a side surface and for emitting illuminating light from the back surface thereof, and a transparent material filled between the light guide and the reflective liquid crystal provided at the back side thereof. The reflective liquid crystal is viewed from the side of the front surface of the light guide through the transparent material.

Abstract: The temperature and flow rate of steam introduced to a gas turbine and a combustor is controlled properly through mixing intermediate-pressure steam and high-pressure steam. Thus, two different requirements; i.e., adjustment of steam temperature and securing of a sufficient steam flow rate, can be satisfied simultaneously. As a result, it becomes possible to simultaneously achieve control of the clearance of the blade ring of the gas turbine by means of steam and cooling of the combustor by means of steam.

Abstract: A bicycle is provided with a frame and a drive portion. The frame is at least partially hollow, and at least part of the drive portion is disposed in an interior of the frame. The drive portion includes a crank and a plurality of transmission means, in which one of the transmission means rotates another transmission means at a rotational speed higher than a rotational speed of the crank, which in turn rotates the rear wheel of the bicycle.

Abstract: The frame (2) for a collapsible bicycle of the present invention includes a head tube (10), a front frame (11), a rear frame (12), a handlebar locking mechanism (14)and a frame locking mechanism (17). On the head tube (10) the front fork (4) is mounted to support the front wheel (5). The front frame (11) is coupled to the head tube (10) in a manner that allows the leading edge to freely rotate perpendicular around the axis using a bearing (13). The rear frame (12) is coupled to the front frame (11) in a manner that allows the leading edge to freely rotate perpendicular around the axis using a hinge (16) as well as be able to support the rear wheel (6) on other edges. The handlebar locking mechanism (14) locks and freely releases the head tube (10) and front frame (11). The frame locking mechanism (12) locks and freely releases the front frame (11) and rear frame (12).
