  • Publication number: 20220278249
    Abstract: Provided are: a near infrared light-emitting semiconductor element that does not contain any harmful elements and that makes it possible to obtain near infrared light of a stable wavelength in a narrow band regardless of the operating environment; and a method for producing the near infrared light-emitting semiconductor element. GaN is used in the method for producing a near infrared light-emitting semiconductor element, and an active layer added in order to substitute Tm with Ga is formed on GaN in a reaction container at a growth rate of 0.1-30 ?m/h without removal from said reaction container using an organometallic vapor phase growth method under temperature conditions of 600-1400° C. in a series of formation steps including formation of a p-type layer and an n-type layer. GaN is used in the near infrared light-emitting semiconductor element, and said near infrared light-emitting semiconductor element includes an active layer sandwiched between an n-type layer and a p-type layer on a substrate.

  • Patent number: 7452301
    Abstract: A torque-coupling device comprising a hydraulically actuated friction clutch pack and a gerotor pump provided for generating hydraulic pressure actuating the friction clutch pack. The gerotor pump is selectively actuated by a device external to the gerotor pump and the friction clutch pack, such as an electric motor, friction brake, electro-magnetic clutch, friction mechanism utilizing a magneto-rheological fluid, electro-magnetic brake, etc. The externally driven gerotor pump may be further provided with torque-multiplication gearing, and/or an electronic controller to modulate the actuation of the pump in order to provide flexible control of the hydraulic pressure generated by the gerotor pump.
