IPC: H01S5/024
Filed: 1997-10-27
Abstract: The high-power diode laser comprises a laser bar (1) that is provided with breaking locations (7.1, 7.2) at predetermined positions. The laser bar is soldered to a heat sink (2) having a smaller thermal expansion coefficient. After being soldered and during cooling, the breaking locations defined by grooves (5.1, 5.2, 5.3) cause the bar to break at defined locations between the single laser diodes (6.1, 6.2, 6.3 and 6.4). As a result of the physical division of the laser bar (1), it is possible to use a solder (8) such as gold/tin which has low ductility at room temperature, since destruction of the single laser diodes (6.1, 6.2, 6.3 and 6.4) of the laser bar (1) as a result of mechanical stresses can be ruled out. The heat sink (2) may comprise diamond.

Title: Improved hair straightening emulsion
Inventor: DARKWA ADU GYAMFI
IPC: A61K/
Filed: 1996-08-22
Abstract: An improved highly alkaline hair straightening emulsion and a two component system for preparing the emulsion are provided. The emulsion employs a combination of strong nitrogenous organic base and alkali metal hydroxide in the presence of an alkaline earth metal cation. Neither the amount of the alkali metal hydroxide nor the amount of organic base present in the emulsion is sufficient by itself to effectively permanently straighten naturally curly hair. Alkaline earth metal hydroxides are characteristically ineffective as permanent hair straighteners. However, surprisingly, the combination is effective for achieving permanent straightening of hair within a treatment time of not more than about 30 minutes. In use, the emulsion also substantially avoids scalp skin irritation. Also, hair discoloration and hair breakage are minimized.
