Title: Semiconductor device
Inventor: IIJIMA TETSUO
IPC: H01L29/423
Filed: 1988-01-27
Abstract: PURPOSE:To improve a device in breakdown strength and micronize a cell in size by a method wherein a trench is provided so as to reach a drain region, a gate oxide film is provided onto the inner wall of the trench, and a high concentration reach-through layer is provided. CONSTITUTION:A first conductivity type low concentration layer 3 is formed on a primary face of a semiconductor substrate 2. A trench (deep groove) 11 is provided along a center of a source region 6. The base of the trench 11 reaches to a low concentration layer 3 or a superficial layer of the semiconductor substrate 2 penetrating a channel forming layer 20. A device of this design is formed in such a structure that a gate oxide film 7 is formed on a side wall of the trench 11 and a gate electrode is buried in the trench 11, so that a cell can be decreased in size. On the other hand, a reach-through layer 18 is provided between the substrate 2 and a low concentration layer 2b. Consequently, a device can be preset so as to yield to a breakdown at a required voltage before the base corner of the trench 11 yields to a breakdown.

Title: Optical waveguide, light beam spot converter and optical transmission module
Inventor: KAWAMOTO KAZUTAMI
IPC: G02B6/122
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To obtain an inexpensive small-size optical waveguide and a light beam spot converter which can be disposed between almost any optical parts by forming a clad layer of at least two layers having different refractive indices and forming a core part as discontinuous in the direction along the optical axis. SOLUTION: The core 11a is partially removed in the direction along the optical axis and the removed part is embedded with a clad material 12. Namely, by forming a segment core, the region with weak confinement of light in the core 11a is formed and the length of the core in the y-axis direction in contact with the clad layer having lower refractive index is increased so as to obtain a so-called rib core 11b. The first clad 12 and the second clad 13 are formed as layers having different refractive indices N1, N2, respectively. In this constitution, light in weak confinement bleeds out to the outside of the core and attracted by the clad 12 having higher refractive index. The light is attracted by the rib core 11b to the opposite side to the y-axis. Thus, the beam spot can be enlarged not only in the y-axis direction but in the x-axis direction.

Title: Recovery of tantalum from scrap containing tantalum
Inventor: ENDOU HIROSHI
IPC: C22B34/24
Filed: 1980-02-15
Abstract: PURPOSE: After brought into contact with an inorganic acid solution of scrap containing tantalum, the anion exchange resin is rinsed with a strong acid eluting solution including hydrogen fluoride and additionally rinsed with a specific aqueous solution mixture, whereby high-purity Ta 2 O 5  is recovered from scrap in high yield.  
     CONSTITUTION: Scrap containing tantalum is dissolved in an inorganic acid and the resultant solution is brought into contact with an anion exchange resin. Then, the resin is rinsed with hydrogen fluoride or a strong acidic medium as an eluting solution. During this operation, tantalum forms together with hydrogen fluoride a complex ion TaF 7   2- , which is adsorbed on the resin, meanwhile other metal cations are eluted. At this stage, silicon and niobium also form fluorine complexes, however, the distribution coefficients are so small that they are removed along with other metals. The ion exchange resin is rinsed with an aqueous solution mixture containing hydrogen fluoride, ammonia and an ammonium salt to elute tantalum. The tantalum elute solution is adjusted to 6.0 or higher pH to precipitate Ta(OH) 5 , which is dehydrated with strong heat to form Ta 2 O 5 .

Title: Method for evaluating performance of organic composite steel plate
Inventor: TEJIMA SHIHO
IPC: G01N24/08
Filed: 1995-01-10
Abstract: PURPOSE: To quickly evaluate the performance of an organic composite steel plate without manufacturing an organic composite steel plate by measuring the change in nuclear magnetic relaxation time that is obtained by analyzing a paint for organic film through the NMR for hydrogen nucleus. CONSTITUTION: The relation between the performance of an organic composite steel plate and the property of a paint for organic film shows a correlation that the diffusion state of the paint causes a change in magnetic relaxation time and the performance of steel plate is good in a mixing condition where a paint whose magnetic relaxation time value obtained through the NMR analysis is within a specified range. Therefore, the nuclear magnetic relaxation time reflecting the mobility of molecule is used to judge the diffusion state of paint element that is one condition necessary for the performance of the organic composite steel plate. Namely, when an anti-corrosive additive is added to a melted main resin, it acts on the main resin and changes the molecular movement.  The diffusion and mixing state of the additive at this time gives influence to the mobility easiness of molecules of the main resin in a solvent. As a result, the change in mobility thereof by adding the anti-corrosive additive is detected as the change in nuclear magnetic relaxation time.
