Patent JP-2002241192-A (JP)
Title: Method for producing semiconductor crystal and semiconductor light emitting element
Inventor: NAGAI SEIJI
IPC: C30B25/18
Filed: 2001-02-14
Abstract: PROBLEM TO BE SOLVED: To obtain a high quality semiconductor crystal nearly free from dislocations. SOLUTION: When a substrate layer (a desired semiconductor crystal) of a group III nitride-based compound is grown on a ground substrate having a plurality of projection parts, cavities where no semiconductor crystal is deposited are formed at each of spaces between the projected parts, depending on the size of each projected part, the distance between the projected parts, crystal growth conditions, or the like. Therefore, when the thickness of the substrate layer is made sufficiently larger than the height of the projected parts, an internal stress or an external stress tends to act on the projected parts in a concentrated manner. These stresses act especially on the projected parts as the shear stress, and when the stresses become large enough, fracture occurs at the projected parts.  Accordingly, it becomes possible to easily separate the ground substrate and the substrate layer by the use of these stresses and to obtain the semiconductor crystal independent from the ground substrate. The stresses are more easily concentrated on the projected parts as the sizes of the cavities become larger, and it becomes possible to separate the substrate layer from the ground substrate without failure.

Title: Needle selector for knitting pattern in circular knitting machine and knitting needle used therefor
Inventor: WATANABE HIROYUKI
IPC: D04B15/82
Filed: 2001-02-14
Abstract: PROBLEM TO BE SOLVED: To provide a needle selector for a knitting machine improved in the invention of Japan Patent publication number 47-50350. SOLUTION: Since the fixation of a machine screw is made unnecessary by setting a stopper (9a) on the head of a cam set piece (9) to engage with a holding frame (2), the exchange of a casset cam becomes easy. A first key groove (14) to be connected to the cam set piece and a second key groove (15) to be connected to a projection on the holding frame are arranged on the side of the middle part of the cassette cam, further, the first and second key grooves have different shapes from each other, thus the mistake between the front face and the back face caused by a worker can be avoided. Since a plurality of the cassette cams are used in a block, processing accuracy and assembling accuracy are further increased than that of the case where the cassette cams are stacked one by one, and the processing cost also can be reduced.
