Title: Semiconductor laser
Inventor: SUZUKI MASAMITSU
IPC: H01L21/316
Filed: 1986-12-16
Abstract: PURPOSE:To enhance the luminous efficiency of a semiconductor laser by using a high resistance oxide layer as the buried layer of a buried double hetero junction semiconductor laser to completely confine a current passage in an active layer region so that all currents contributes to laser light radiation. CONSTITUTION:When a positive voltage is applied by an electrode 27 ohmically contacted with a cap layer 25 and a negative voltage is applied by an electrode 28 ohmically contacted with an N-type InP substrate 26 to supply a current, electrons and holes recombine in an active layer 22, and light is radiated. An oxide layer 21 is of a high resistance insulator, and no current flows, but currents supplied externally all concentrate in the layer 22. Thus, a high luminous efficiency can be obtained. Further, since approx. 1.7 of the refractive index of the layer 21 is smaller than approx. 3.2 of the refractive index of the layer 22, the light radiated from the layer 22 is totally reflected on a boundary between the layers 22 and 21, and confined in the active layer. Thus, they can be all produced as effective laser light, thereby improving the luminous efficiency.

IPC: F24D17/00
Filed: 1988-11-25
Abstract: PURPOSE:To prevent the valve from sticking in a flow control valve for controlling the hot water supply so as to prevent an increase of the starting torque by providing two closing position detective means and a timer which outputs a signal after each time that a certain time has passed following the closing of the flow control valve in a setup to drive the valve between the two closing positions. CONSTITUTION:There are provided a first closing position detective means 11 and a second closing position detective means 12 both for detecting closing positions of a flow control valve 5 for controlling the hot water supply and a timing means 13 which outputs a signal after passage of a set period of time following the closing of the flow control valve 5. A control means 9 drives a mixing valve 3 by means of a mixing valve-driving means 4 according to signals from a temperature-setting means 8 and a temperature detective means 7 so as to eliminate a temperature difference therebetween. Therefore, it does not occur for the packing at the water-stopping part in the flow control valve 5 to be squeezed tight for a long time. As a result, the start does not require an increase in the torque and the temperature of the water-hot water mixture can always be maintained at a prescribed point.
