Patent JP-H11345961-A (JP)
Title: Hetero-junction field-effect transistor
Inventor: ANDO YUJI
IPC: H01L21/338
Filed: 1998-06-02
Abstract: PROBLEM TO BE SOLVED: To provide a heterojunction transistor(HJFET), which can decrease a source resistance and a drain resistance without alloy processing. SOLUTION: An InGaAs channel layer 12, an undoped InAlGaAs spacer layer 13, InAlAs electron feeding layers (14A and 14B), an undoped InAlAs Schottky layer 14C, InAlAs first cap layers (14D and 14E), an InAlGaAs second cap layer 15 and an n-type InGaAs cap layer 16 are sequentially formed. Thus, by utilizing the fact that the conducting-band offset of the InAlGaAs/InGaAs interface is lower than the case when InAlAs an InGaAs are directly connected, the electronic barrier formed at the hetero interface (between 16-15 and between 23-12) is lowered. At the same time, the tunnel probability when the electrons are transmitted between the cap layer and channel layer is increased. This is the heterojunction transistor(HJFET) wherein the source resistance and the drain resistance are lowered oven without the alloy processing.

Title: Formation of silica film
Inventor: AZUMA SEIJI
IPC: C23C16/42
Filed: 1998-06-02
Abstract: PROBLEM TO BE SOLVED: To suppress the generation of fine silica powder in film formation by incorporating steam into a starting material contg. silane and oxygen and carrying out a thermal vapor phase reaction. SOLUTION: Among various radicals such as SiH3 and Si(OH)2 formed in a reaction process, an initial polymer of SiO[(SiO)n ] causes the formation of fine silica powder. When steam is incorporated into the gaseous starting material in a steam to silane molar ratio of >=0.5 and film formation is carried out under atmospheric pressure, the formation of (SiO)n is suppressed independently of the concn. of oxygen. In accordance with the increase of the steam to silane molar ratio under conditions which generate fine silica powder in large quantities (350 deg.C reaction temp., 1 atm. pressure and an oxygen to silane molar ratio of 0.5), the selectivity of HSi(OH)3 as a film forming effective component increases, the selectivity of (SiO)n decreases and (SiO)n formation suppressing effect is remarkable in the case of a steam to silane molar ratio of >=0.5.  By the suppressed generation of fine silica powder, labor for the maintenance of an apparatus is reduced and pinholes in a formed silica film are diminished.

Title: Wound treating device
Inventor: TOOMASU DEII UERUDON
IPC: A61B17/03
Filed: 1994-07-05
Abstract: PURPOSE:To easily and rapidly treat the wound of a blood vessel, etc., without requiring skill. CONSTITUTION:Terminals 32, 74 of pipes 28, 72 having an internal cavity 34 are provided with diaphragms 36, 84. These diaphragms are movable between the retreat position in the internal cavity and the expansion position where the diaphragms are expanded like a balloon. A treating agent 38 can be housed in the diaphragms when the diaphragms exist at the retreat position. This treating agent is added to the wound A of the blood vessel F by inserting the terminals of the pipes near to the wound of the blood vessel, then expanding the diaphragms by pressurized fluid. The outflow of the blood from the wound is prevented by the diaphragms expanded like the balloon. The treating device is thus held in this position. The terminals of the elastic diaphragms are inserted to the inner side of wound of the blood vessel at the time of using a flow rate controller having the tubular members and the elastic diaphragms at their terminals. The elastic diaphragms are then expanded and the wound of the blood vessel is closed by the elastic diaphragms expanded like the balloon. The inflow of the treating agent into the blood vessel is thus prevented and the wound is rapidly treated.

Inventor: TABATA KUNIAKI
IPC: H04N1/04
Filed: 1982-09-06
Abstract: PURPOSE:To facilitate picture magnification and reduction by storing and referring to a periodic train of the coordinates changes in the lattice points of a new picture obtained by magnifying and reducing a two-dimensional picture in a lattice array and the periodic train of the coordinates differences in the new lattice points and in the old lattice points surrounding the new one. CONSTITUTION:A two-dimensional picture in a lattice array is magnified or reduced and the coordinates of the lattice are converted from a system Pij to a system Qmn. When a picture element is coincident with a lattice point Qmn or the right upper closest one is denoted as PXmYn, the Qmn is included in the lattice area formed on four points PXmYn, PXm+1Yn, PXm+1Yn+1, and PXmYn+1. The longitudinal and the lateral coordinates of Qmn based upon the original picture are um and vn. The periodic train of DELTAXm and Yn and the periodic train of um and vn, When DELTAXmidenticalXm+1-Xm and DELTAYnidenticalYn+1-Yn are defined, are stored in a memory previously. The conversion from the system Pij to the system Qmn is carried out by referring to those periodic trains to calculate the density of the picture elements on the same column. Thus, the calculation of every picture element is unnecessary and high-speed processing is realized.
