Patent JP-H0637387-A (JP)
Title: Semiconductor laser device and its manufacture
Inventor: KATO YOSHIAKI
IPC: H01S5/00
Filed: 1992-07-15
Abstract: PURPOSE:To stabilize an operation current and characteristics of a buried crescent laser. CONSTITUTION:A stripe 20 having a certain width is formed on the main surface of a semiconductor substrate 1 and n-type buried layers 21 which are to be current blocking layers are formed on both the sides of the stripe 20. The stripe 20 is used as a current path region and an operation current can be stabilized. Then a p-type InP layer 22 and a cap layer 23 are built up and etched to form a trench 24 whose bottom reaches the stripe 20. After that, a lower buried layer 27, a crescent active layer 28, an upper buried layer 29 and a cap layer 30 are successively formed on the substrate main surface side. The purpose of the lower buried layer 27 is to prevent the active layer 28 from being brought into electrical contact with the n-type InP buried layer 21 and its thickness can be small. The variation of the thickness can be reduced by the reduction of a treatment time for forming the layer. As the active layer depends upon the thickness of the lower buried layer, the variation of the thickness of the active layer is also reduced, so that the characteristics can be stabilized.

IPC: F01L1/18
Filed: 1981-11-24
Abstract: PURPOSE:To reduce the frictional sound and friction loss of the titled gear by providing a rotatable tappet on one end of a locker arm, in the valve gear in the internal combustion engine using the locker arm. CONSTITUTION:The locker arm 12 rotatably supported by the locker shaft 12 has a tappet 14 at its one end 12a on the side of a cam 13, and another end 12b making contact with an end of a valve stem similarly as the conventional device. The tappet 14 comprises a disc-shaped head, a seat 16 and a shaft 17.  When the cam 13 is rotated and driven, the tappet 14 is rotated in accordance  with the movement of the cam 13.
