Title: Forming method of semiconductor device
Inventor: MIYAZAWA SEIICHI
IPC: H01L21/203
Filed: 1995-10-19
Abstract: PROBLEM TO BE SOLVED: To prevent the removal of P which is liable to desorb from the surface, by cleaning the surface while it is irradiated with As and P of As/P supply ratio larger than that at the time of manufacturing a lower side semiconductor layer which is to be regrown, when a semiconductor film is regrown on a semiconductor layer having V group elements. SOLUTION: In the growth condition of an upper part light guide layer 5 (a substratum layer), TMI 10%, TEG 5%, PH3 7.7sccm, and AsH3 0.3sccm are added as supplying material for growth. As/P supply ratio is 0.039, but 0.5, a ratio larger than it, is selected as a cleaning condition, and the ratio of AsH3 is made large. When constituent elements come out from a flat part and defects are formed, characteristics of a device of the flat part are deteriorated. Especially vapor pressure of P is high, and it is the main reason of deterioration of characteristics. Then the surface is covered with As which is more stable on an InGaAsP surface as compared with P and hardly reevaporated. When the surface is covered with As by increasing the ratio of As, the removal of P which is liable to desorb from the surface can be prevented.

Title: Reduction method for flow water pipe's opening for side thruster in ship
Inventor: HORI TATSUO
IPC: B63H25/42
Filed: 1998-09-10
Abstract: PROBLEM TO BE SOLVED: To increase cruise speed and reduce wave shock by horizontally arranging a chord portion of a half-moon shaped disk, welding the upper part of an opening at an elliptic arc portion to block a part of the opening, welding a linear portion of a training wall's roof with the chord portion of the half-moon shaped disk, and welding it with the inner peripheral wall of a flow water pipe at an inner contact portion. SOLUTION: One-third to a half of area of an opening (suction/drainage opening) of both right and left gunwales of a flow water pipe 2 is downward horizontally closed by setting a chord portion of a half-moon shaped disk 5 comprising an elliptic arc portion and the chord portion, and the elliptic arc portion is welded to the upper portion of the opening. A roof is mounted so as to provide rising gradient from the bottom corresponding to the chord portion of the half-moon shaped disk 5 toward the inside of a cylinder of the flow water pipe 2. This roof, as a training wall's roof 6, turns water flow in the flow water pipe 2 from horizontal direction to slightly tilting downward direction, and reduces occurrence of surface flow. Thus, the reduction of the suction/drainage opening (opening) can shrinks a hole on an external plate of a hull, and the reduction of the area of the opening can increase shipping speed and mitigates wave shock.

IPC: B82B1/00
Filed: 1993-11-29
Abstract: PURPOSE:To provide the recording medium by which the highly densified recording can be realized by stably forming recording magnetic domains smaller than the light spot diameter. CONSTITUTION:This recording medium has the magnetic film 3 formed on the substrate 1 directly or through the dielectric layer 2 and on the surface of the substrate 1, flat part regions and fine, recessed and projecting part regions are formed alternately and adjacently to each other.
