Title: Offset structured mos transistor and manufacturing method thereof
Inventor: YAMADA MAKOTO
IPC: H01L29/78
Filed: 1992-06-10
Abstract: PURPOSE:To avoid the deterioration in operational performances of the MOS transistor by a method wherein the extension of a depletion layer to an offset region is facilitated for adjusting the high voltage applied on a gate end when a high voltage is applied on a drain region while suppressing the stiffening resistance in an offset region. CONSTITUTION:This offset structured MOS transistor 1 provided on a semiconductor substrate 11 is formed of an offset region 16, the first impurity diffused region 20 in lower concentration than that of a drain region 17 and the second impurity diffused region 21 formed on a part of the upper layer of said region 20 in the impurity concentration between the first impurity diffused region 20 and the drain region 17 in the connecting state to the drain region 17.

Title: Gas sensor
Inventor: KANAMORI MASAAKI
IPC: G01N27/12
Filed: 1993-06-24
Abstract: PURPOSE:To increase the gas sensitivity of a sensor by forming a sensitive section containing an added catalytic substance on a substrate at a position away from the surface of a metal oxide sensitive film by a distance equal to or more than the prescribed value along the depthwise direction of the substrate. CONSTITUTION:A tin oxide film is generally formed on a substrate such as an alumina substrate and a heat resistant glass substrate. A catalytic substance, for example, Pd is added to a sensitive section so formed, thereby forming a Pd added tin oxide film. In this case, the film formation is so made that the position thereof is equal to 1/2 or more of total thickness from the surface of the sensitive film in a depthwise direction, and the film is formed into thickness approximately between 20nm and 30nm. When a metal oxide layer containing a catalyst is formed at such a position, the dissipation ratio of combustible gas (gas to be detected) in the atmosphere of a sensitive film surface layer is lowered, and much combustible gas can be made to arrive at the inside of the combustible gas sensitive film. Consequently, the resistance value of the whole of the sensitive film effectively drops, depending upon the concentration of ambient combustible gas, and the sensitivity thereof as a gas sensor can be increased.

Title: Device for movement of polarization pattern
Inventor: FUUBERUTO ZAIBERURE
IPC: G02B5/30
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To manufacture linear polarization in different polarization directions, band by band, by employing constitution having bands which are mutually limited on a light output side and have at least intermittently different polarization directions. SOLUTION: This device has the constitution having the bands which are mutually limited on the light output side and have at least intermittently different polarization directions. Namely, incident light with which a liquid crystal layer is oriented, band by band, in different directions after passing through the liquid crystal layer is polarized and changes in its plane of polarization according to an oriented pattern. Preferably, the bands have different forces of optical rotation like the plane of polarization of the incident linear polarized light rotates at various angles. It is better to understand that the rotational forces represent the capability to rotate the polarization direction with the light of twisted liquid crystal and the capability to generate various polarization directions by double refraction.  The orientation of the liquid crystal layer can be determined permanently by a corresponding structured oriented layer or dynamically by a liquid crystal cell having an electrode.

Abstract: PROBLEM TO BE SOLVED: To reduce tritium inventory and also reduce the permeability to a cooling channel to improve the safety by changing the atomic tritium flying to a plasma opposed surface into molecular form. SOLUTION: A composite membrane 13 and an armature 8 are arranged with a small space on the surface opposed to plasma of a nuclear fusion device, and the membrane 13 is formed of a surface layer 9 of a material having a high hydrogen dissociation potential such as carbon, a diffusion layer 10 of a material having a dissociation potential lower than the layer 9 such as niobium, and a bonding layer 11 of a material having a further lower dissociation potential such as niobium oxide.
