Title: Semiconductor light emitting device and method of fabricating the same
Inventor: INABA YUICHI
IPC: H01S5/00
Filed: 1996-07-10
Abstract: PROBLEM TO BE SOLVED: To fabricate a ridge waveguide semiconductor laser by a simple process. SOLUTION: On an n-Inp substrate 101, an n-InGaAsP waveguide layer 102, a multi-quantum well active layer 103 constructed by an InGaAsP well layer and an InGaAsP barrier layer, a p-InGaAsP waveguide layer 104, and a p-InP cap layer 105 are sequentially epitaxial grown by using the metal organic vapor phase epitaxial growth method, thereby forming a semiconductor multilayer structure. An SiO2 film is deposited on the p-InP cap layer 105 by the CVD and is patterned. An insulating film mask 106 is formed by wet etching. On the n-InP substrate 101 provided with the insulating film mask 106, a p-InP cladding layer 107 and a p-InGaAs contact layer 108 are sequentially epitaxial grown. Further, the p-InP cladding layer 107 and the p-InGaAs contact layer 108 are grown only in a region of the opening part of the mask.  Consequently, the ridge waveguide semiconductor laser is automatically formed. In the method of fabricating the laser, since the width of the ridge can be accurately specified, ridge formation with high uniformity can be realized.

Abstract: PURPOSE:To enable a work of transferring a subject between a stretcher and a top plate of examination table to be carried out easily and safely by fitting an auxiliary top plate, which have a shape for covering a clearance between the stretcher and the top plate of examination table, to the examination table. CONSTITUTION:An auxiliary top plate 6 is housed under a foot side of top plate 1 except for a time of transferring a subject so that it does not come into an X-ray field during X-ray examination. At that time, a linear movement along a bearing 8 of a guide shaft 7, which is fixed to the auxiliary top plate 6, is at the most contracted position, and one end of the auxiliary top plate 6 is held by a stopper 9, so that a rotation of the guide shaft 7 is kept stopping while the auxiliary top plate is housed. When the auxiliary top plate 6 is pulled out to a maximum, the holding of the auxiliary top plate 6 by the stopper 9 is taken away and the rotation of the guide shaft 7 is set free. Then, the guide shaft 7 is rotated so as to make one side face of the auxiliary top plate 6 put on an edge of the breast-belly part side face of the top plate 1. It is possible to carry out a work of transferring the subject easily and safely by using this equipment.

Title: Gate circuit
Inventor: SUGIMOTO MASUNORI
IPC: H03K17/687
Filed: 1986-07-31
Abstract: PURPOSE:To suppress hot carrier effect without lowering a source voltage and to prevent an operation speed from decreasing by connecting MOSFETs in specifie connection constitution. CONSTITUTION:When an input to an input terminal 13 varies to turn on an MOSFET 3, a current flows from an output terminal 14 to a voltage source VSS through MOSFETs 3, 4, and 5 and the potential at the output terminal 14 varies toward the VSS. When, however, the threshold voltage of the MOSFET 4 is denoted as VT4, the MOSFET 4 is turned off if the potential at a connection point 11 is held at SSS+VT1 and the potential at the outpnt terminal 14 does not vary any more. Then, when the MOSFET 3 is turned off with a potential applied to the input terminal 13, a current flows from a power source VDD to the output terminal 14 through the MOSFETs 1 and 2 and the potential at the output terminal 14 varies toward the VDD. When, however, the potential at the output terminal 14 rises up to V1-VT2, the MOSFET 2 is turned off, so the potential does not rise any more.
