Abstract: PURPOSE:To improve the sealing for a II-VI compound shortwavelength semicon ductor laser which uses III-V semiconductor as the substrate material or the electrode contact material by reducing the voltage reducing the voltage drop at the electrode part and increasing the band gaps between an active layer, guide layer and a clad layer. CONSTITUTION:Guide layers 45 and 47 formed of CdxZn1-xSySe1-y four-element mixed crystal are formed to sandwich an active layer 46, and clad layers 44 and 48 formed of Mgx'-Zn1-x'-Sy'-Se1-y' four-element mixed crystal are formed on the planes opposite to the active layer 46 among the top and bottom planes of the guide layers 45 and 47. A short-wavelength light emitting element is formed on the planes opposite to the guide layers 45 and 47 among the top and bottom planes of the clad layers 44 and 48. Thus, the element has a hetero barrier relaxation layer 50 which reduces the energy band gap step by step or continually as it goes far from the active layer 46 and an electrode 54 which is connected to the hetero barrier relaxation layer 50 directly or through a III-V semiconductor layer 51.

Title: Polarization control element and solid laser device
Inventor: HIUGA HIROAKI
IPC: G02B5/30
Filed: 1992-10-16
Abstract: PURPOSE:To obtain the polarization control element which linearly polarizes a solid laser beam and suppresses the insertion loss of a resonator as much as possible by cutting birefringent crystal at an angle. CONSTITUTION:The birefringent crystal has its light incidence and projection end surfaces cut at an angle to its optical axis and is so adjusted in thickness and end surface reflection factor so as to have function as Fabri-P'erot etalon. When the laser beam 10 is made incident on the polarization control element 15 which is thus cut at the angle, the laser beam is split into an ordinary light beam 16A and an extraordinary light beam 16B. The solid laser device which has the polarization control element in the resonator selects and oscillates only one of the two light beams 16A and 16B according to the position of a resonator mirror 14. Consequently, the laser beam 10 emitted from the resonator is linearly polarized.

Title: Fuel cell feed system
Inventor: MIZUGUCHI KENICHI
IPC: H02M3/00
Filed: 1988-11-04
Abstract: PURPOSE:To effectively use a fuel cell by supplying the rated output of the fuel cell to a load device from the fuel cell and supplying the shortage from a rectifier, to which the output of a DC output power source like a commercial power source or an engine generator of another system is inputted, at the time when the load device consumes power beyond the rated output of the fuel cell. CONSTITUTION:When the total current I0[A] supplied to two load devices 3 is larger than an output current I1[A] of a DC-DC converter 2 by DELTAI0[A] because the power consumption of a load is increased, the output current I1[A] of the DC-DC converter 2 is scarecely changed and the output current of a rectifier 5 takes charge of DELTAI0[A]. Consequently, I0[A]=I1+I2[A] is true, and they properly take charge of the load. That is, the output of a fuel cell 1 is kept at the rated value, and the increment of the power consumption of the load is supplied from a commercial power source (or an engine generator) 4. Thus, the rated output is supplied to load devices 3 from the fuel cell 1, and the other shortage is supplied from the DC output power source of another system.
