Title: Reflection-type light-emitting diode
Inventor: SUEHIRO YOSHINOBU
IPC: H01L33/62
Filed: 1994-07-22
Abstract: PURPOSE:To make it possible to control almost all the directions of light beams emitted from a light emitting element, by defining one point located near to an intersection of a curve and a focus passing line in parallel with an axis and the other point of intersection on the focus side from the axis, and forming a concave reflection face in a way that a line between these points is turned around the axis. CONSTITUTION:A reflective face 14 is formed around a light emitting element 11. A point (X) on a light emitting face is defined as a point located near to an intersection of a parabola and a parallel line with an axis (Z) at a center (O) of the light emitting face. The point (X) passes a point (f) formed in a place other than the location of an electrode. On the other hand a point (X') is defined as an intersection of a parabola and an almost vertical line to the central axis (Z). The point (X') is located on the point (f) side from the central axis (Z). The reflection face with a concave shape is formed in a way that a line between X to X' is rotated around the axis (Z). As a result, almost all emitting directions of light beams from the light emitting element 11 can be controlled and the intensity of light at the central axis can be increased.

IPC: B41J2/175
Filed: 1987-07-31
Abstract: PURPOSE:To provide a miniaturized and light-weight accumulator by arranging an elastic container in an ink passage or a hermetically sealed space connected to the former. CONSTITUTION:Ink in an ink chamber 45 is energized by a pump 46 and then is supplied to an ink jet recording head 51 through an accumulator 49.

Abstract: PURPOSE:To shorten the time for mixing, agitating, etc., powder by providing a treatment tank which is rotationally driven by a floating frame, supporting means which supports the supporting frame freely rotatably, rotational driving means which rotates the supporting frame to the supporting means, etc. CONSTITUTION:The raw materials in the treatment tank 36 repeat the motion of large and small circles and the mixing of the raw materials is executed when the treatment tank 36 is continuously rotated in 2 deg. of freedom as shown by an arrow H and arrow I. The raw materials in the treatment tank 36 are mixed while the sizes and directions of the rotating motion are successively changed. The materials which are large in specific gravity and have the tendency to stagnate on the lower side of gravity or the outer side of centrifugal force are prohibited from staying at one place. As a result, even the raw materials having large differences in the specific gravity are homogeneously mixed. Since the region acting on the raw materials extends over approximately the entire inside surface part of the treatment tank 36, the raw materials are efficiently and thoroughly mixed.

Abstract: PURPOSE:To dissipate heat yielded in a semiconductor element through both a heat sink and a cap, by linking the heat sink and a cap part with heat conductors having excellent heat conductivity. CONSTITUTION:A heat sink serves a role of a stage part, on which a semiconductor element 10 is mounted.
