Title: Manufacture of thin film transistor
Inventor: KOUDEN MITSUHIRO
IPC: H01L29/78
Filed: 1986-05-23
Abstract: PURPOSE:To improve TFT characteristics by causing transparent conductive films to be shaped as patterns and forming a source interconnection consisting of a metallic film after etching the transparent conductive films and n<+>-a-Si films by using negative type regists as masks. CONSTITUTION:Negative type regists are exposed from the side of a glass substrate 1 and are themselves adjusted to a gate electrode 2 to form negative type regist films 9 which are shaped as patterns. A total film thickness of a -Si semiconductor film 4 and n<+>-a-Si film 7 is less than 1000 Angstrom  in order to easily attain a rear exposure. And then, the negative regist films 9 is used as masks and after transparent conductive films 8 and n<+>-a-Si films 7 are shaped as the patterns by etching, the negative type regist films 9 are peeled off. Subsequently, the transparent conductive films 8 are shaped as the patterns in given forms to form a source interconnection 10, resulting in the formation of a source electrode 11 and drain electrode 12. The above electrodes 11 and 12 are connected by ohmic contact to the a-Si film 4 consisting TFT semiconductor film through n<+>-a-Si films 7 which are left at respective interfaces. Thus, the above arrangement for interconnection improves TFT characteristics.

Abstract: PURPOSE:To reduce a capacitance between a base and a collector by reducing an area of a base region and to improve a high-frequency characteristic by a method wherein outer base regions at both ends of an intrinsic base region are connected by a P-type diffusion layer under an insulator layer. CONSTITUTION:An N-type buried diffusion layer 2 and a P-type buried diffusion layer 3 are formed selectively on a P-type singlecrystal silicon substrate 1. In addition, an N-type epitaxial layer 4 is formed on them. In addition, a P-type insulating isolation diffusion layer 5 is formed by a selective diffusion operation from the surface of the N-type epitaxial layer 4; the P-type buried diffusion layer 3 and element regions such as transistors, resistances and the like are insulated and separated. In addition, the surface of the layer 4 is oxidized selectively; thereby, an insulator layer 6 composed of silicon dioxide is formed. During this process, a P-type diffusion layer 20 is formed selectively in one part under the insulator layer 6 so as to be aligned with the insulator layer 6. In addition, a P-type intrinsic base region 7 and P-type outer base regions 8, 8' are formed in the element regions decided by the insulator layer 6. When this P-type diffusion layer 20 is formed, it is not required to form a contact hole to be connected to an outer metal wiring part with reference to the second P-type outer base region; an area can be reduced by this elimination.

Abstract: PROBLEM TO BE SOLVED: To eliminate the need of a heat treatment for forming a layer type perovskite after an upper electrode is formed by a method wherein after a bismuth layer type compound precursor layer is formed, the precursor layer is rapidly heat-treated. SOLUTION: A coating film 12 is formed on a substrate 11 and thereafter (S1), the film 12 is dried to form (S2) an StBi2 Ta2 O9 precursor layer 13. After that, the layer 13 is heated by an RTA in an oxygen atmosphere.

Abstract: PURPOSE:To obviate alignment work of holes for fitting a guide vane stem and make easy the fitting work thereof by supporting the lower stem of the guide vane on a groove formed on the lower cover via a bearing and pouring a curing agent into a space between the groove and the baring. CONSTITUTION:In assembling a guide vane 1, an upper stem 1B, a bearing 4 and an upper cover 2 are first assembled. Then, a lower stem 1A is assembled into a bearing 5 and positioned in a groove 10.

In this state, a curing agent is poured into a space between the groove 10 and the bearing 5, and cured. At this stage, each of the aforementioned bearings 4 and 5 falls in an automatically aligned state, due to the weight of the guide vane 1 and this vane 1 is supported in that state, thereby making it not always necessary to carry out the co-alignment machining of the grooves of upper and lower covers 2 and 3, and obviating the alignment of upper and lower holes for guide vane stem assembly.

Title: Image display device
Inventor: ONISHI IKUO
IPC: G02F1/1335
Filed: 1992-04-14
Abstract: PURPOSE:To reduce the lowering of picture quality due to a state where a picture element is observed in point shape and discontinuously and to display high resolution feeling by arranging an optical low-pass filter consisting of a one-dimensional diffraction grating on the display route of a liquid crystal display panel. CONSTITUTION:This device is equipped with the liquid crystal display panel 1 on which a large number of picture elements 4 of dot shape are arranged in two-dimensional fashion, and the optical low-pass filter 2 consisting of the one-dimensional diffraction grating is installed at the display route of the image display part of the liquid crystal display panel 1. A high frequency component in one direction on the liquid crystal display panel 1 is blocked by the optical low-pass filter 2 consisting of the one-dimensional diffraction grating, which blurs the dot of the picture element. Therefore, it is possible to reduce the lowering of the picture quality due to the state where the picture element of the liquid crystal display panel 1 is observed in point shape and discontinuously. Also, since the optical low-pass filter 2 is of one-dimensional, no blurring occurs in the dot of the picture element in another direction where the high frequency component is not blocked, therefore, the lowering of the picture quality due to the blurring can be reduced as a whole.

Title: Improvement in flow flux of ultrafiltration
Inventor: TANEKAWA TETSUO
IPC: B01D61/14
Filed: 1982-07-13
Abstract: PURPOSE:To enhance the permeability of an aqueous solution, by a method wherein an aqueous solution containing a high molecular substance such as protein is preliminarily subjected to heat treatment and said high molecular substance is modified and coagulated to prevent the clogging of an ultrafiltration membrane. CONSTITUTION:For example, 48l glutamic acid fermentation liquid is subjected to heat treatment at 60-70 deg.C for 10min to be subjected to ultrafiltration by using a hollow yarn comprising a polysulfone membrane with a ultrafiltration limit M.W. of 6,000. When heat treatment is not carried out, the rapid reduction in a flow flux is recognized directly after ultrafiltration is started but, in the case of heat treatment, the lowering in flow flux is extremely low. As the result, in a filtration time until the amount of a filtered liquid reaches 38l, 5hr is required in the case of untreatment but, in the case of treatment 3hr is required. As apparent from the forgoing, by preliminarily carrying out heat treatment of a solution in the case of ultrafiltration treatment of a microbiological fermentation liquid of amino acid, the flow flux of the solution, that is, the filterability of a membrane can be remarkably enhanced and efficient treatment thereof can be carried out.
