Title: Charge-injection type semiconductor laser
Inventor: NOBUHARA HIROYUKI
IPC: H01S5/00
Filed: 1987-05-09
Abstract: PURPOSE:To execute a light-extinction operation (a pinch-off operation) at high speed by a structure wherein a carrier during its traveling gets over a barrier of a superlattice layer and is injected into an active layer so that the carrier is extinguished quickly. CONSTITUTION:While a potential difference is caused between an n-electrode (B) 19 and an n-electrode (A) 18, an electron travels from a disorder layer 16 through a superlattice layer 15 toward a disorder layer 17. The electron becomes a hot electron during traveling; it gets over a quantum barrier layer of the superlattice layer 15 and is injected into an active layer 14 under an electric field of a p<+> electrode 20 and between the n-electrode (B) 19 and the n-electrode (A) 18. It couples with a hole in the active layer, and the light is emitted. Because this semiconductor laser emits light only when an electric charge gets over the quantum well barrier layer and is injected, few electric charges remain in the active layer; when a signal is turned off, the carrier is extinguished so quickly; a light-extinction operation is executed at high speed.

Abstract: PROBLEM TO BE SOLVED: To surely prevent oil from blowing out or leaking by forming a breather chamber in a cover part fitted to the opening end part of a main body part, and forming an oil reflux passage communicating with a specified spot in the case where pressure is lowered. SOLUTION: A breather camber 29 is formed on the above position of the rotary axis of a ring gear 9 in a casing cover part 1. The vicinity of the outer circumferenctial part of the ring gear 9 is communicated to the breather chamber 29 through a small opening part formed on a deflector 30, and a space part A1 on a far place from the ring gear 9 is communicated to the breather chamber 29 through a communicating pipe 35. Consequently, air is exhausted through a breather 32, and pressure rise of the inner space A1 of a casing 1 is restrained. Meanwhile, because the bottom part of the breather camber 29 is communicated with the stop where pressure is lowered by a pump action accompanying rotation of a conical roller bearing 4 in the inner space A1 by an oil reflex passage 33, oil is sucked from the breather chamber 29, and reflux to the inner space A1 is promoted.
