Title: Manufacture of embedded type semiconductor laser element
Inventor: MATSUBARA KUNIO
IPC: H01S5/00
Filed: 1988-10-03
Abstract: PURPOSE:To realize a manufacturing method which is shorter than a conventional one in a manufacturing process by a method wherein a current constriction layer is formed in such a manner that it is made not to grow up to the surface of a contact layer but made to stop growing at a halfway point of the thickness of the contact layer, and a second contact layer is made to grow in succession. CONSTITUTION:A first clad layer 2, an active layer 3, a second clad layer 4, and a contact layer 5a are formed in this order on a substrate 1. Next, the surface of the laminated body is selectively etched in a thicknesswise direction up to a halfway point of the second clad layer 4 through a photolithography method, in which an SiO2 film 7 is attached to the surface of the laminated body and resist is applied, for the formation of a stripe-like mesa which has a specified width and is composed of the second clad layer 4, the contact layer 5a, and the SiO2 film 7, and the resist is removed. Then, a current constriction layer 6 is so formed on both the side faces of the mesa on the laminated body as to make its upside level with a halfway point of the thickness of the contact layer 5a, in succession a contact layer 5c is formed on the current constriction layer 6 as being in contact with the contact layer 5a in one piece at both the side faces of the mesa, and the SiO2 film 7 left on the surface is removed.

Title: Space drawing method, virtual space drawing device, and storage medium
Inventor: KATAYAMA AKIHIRO
IPC: H04N13/04
Filed: 1999-09-02
Abstract: PROBLEM TO BE SOLVED: To obtain drawing of high real time property by storing space data in 1st format in a 1st memory, downloading space data of a virtual object within a predetermined range from a detected current viewpoint position from the 1st memory to a 2nd memory when the space data are not present in the 2nd memory, and drawing a virtual space according to the space data in the 2nd memory. SOLUTION: When ray space data corresponding to a viewpoint position are not present in a memory 27 yet, billboard image are used instead. The ray space image, however, is given priority to the billboard. Namely, a virtual image of an arbitrary viewpoint position can be generated with high precision on the basis of the ray space data from specific viewpoint position. Therefore, when the ray space data are present in the memory 27, the virtual image is generated according to the current viewpoint position and presented on a CRT.

Abstract: PURPOSE:To prevent shortening the life of a copper converter caused by the errosion of tuyere bricks, by specifying the oxygen pressure of a top-blown lance and the distance between the front end of the lance and the surface of a molten metal when blowing air from a tuyere and oxygen from the top-blown lance into the molten metal. CONSTITUTION:In a copper converter 1, ordinary air is blown into a molten metal 3 from a tuyere 2 and, at the same time, oxygen or air enriched in oxygen is blown from a top-blown lance 4 into the molten metal 3. When the air and oxygen are blown, the distance between the surface of the molten metal measured when the molten metal is rested before starting the blowing and front end of the lance 4 is set at <=0.4m and, at the same time, pressure for supplying the oxygen, etc., to the lance 4 is set at >=1kg/cm<2>. Moreover, by adjusting the average oxygen density of the mixture of the air from the tuyere 2 and air enriched in oxygen or oxygen blown from the top-blown lance 4 in such a way that the average oxygen density is made higher at the initial stage of the matte concentrating period and lowered as time goes on, enlargement of the material adhering to the lance can be prevented.

Filed: 1989-09-28
Abstract: PURPOSE:To record a high quality character by a method wherein a thickness of a line of character information is corrected based on reflected density of a recording part and a non-recording part on a recording material. CONSTITUTION:A recorder 10 reads an appropriate outline data from an out-line font 12 by a command from a host computer 15, and expands it to a bit data inside a control circuit 11, which is printed with a recorder unit 13.
