Title: Manufacture of semiconductor device
Inventor: ITOU TOSHIYO
IPC: H01L21/033
Filed: 1987-02-24
Abstract: PURPOSE:To set a sufficiently small inter-junction distance without causing the deterioration, etc., of element characteristics by forming a third film into a fourth trench section shaped by a second side wall. CONSTITUTION:A first side wall 8 is formed onto the side wall of a first trench section 6 shaped to a first film 5, and a second film 11 is formed into a second trench section 10 shaped by the side wall 8. The first side wall 8 is removed, and a second side wall 13 is formed into a third trench section 12 shaped by the first and second films 5, 11. Lastly, a third film 15 is formed into a fourth trench section 14 shaped by the second side wall 13. That is, when a first semiconductor region is formed under the second film 11 and a second semiconductor region is shaped under the third film 15, the inter-junction distance of these two semiconductor regions is specified by the width of the second side wall 13. Consequently, the width of the side wall is easily controlled at a small value. Accordingly, the inter-junction distance of the two semiconductor regions can be reduced.

IPC: B01J19/24
Filed: 1980-03-28
Abstract: PURPOSE: To prevent the formation of drain and perform effective soot blowing by discharging the drain to the outside of the reaction apparatus prior to soot blowing by means of the drain removing conduits provided at both ends of a steam injection pipe and injecting steam to the catalyst layer from the injection nozzles of the multiple holes, thereby rescattering and removing the stuck material.  
     CONSTITUTION: In the state that an injection pipe 10 is put in a housing chamber, high-pressure steam 5 is passed through a feed pipe 6 to discharge drains 17, 17' to the outside of the reaction apparatus from drain-removing conduits 13, 13'. Then, the injection of injection nozzles 7, 10 having multiple holes is started to inject the high-velocity current 4 of the steam ejected from the nozzles 7 uniformly to the catalyst surface 1 so that the solids in the gas inlet end faces and the catalyst  through-holes are rescattered to gas outlets and are removed. The injection pipe 10 reiteratively moves over the entire width of the catalyst layer 1 in an arrow 8 direction, thereby blowing the high-velocity gas current 4 over the entire surface of the water gas inlets of the catalyst layer 1. Upon completion of soot blowing, the injection pipe 10 is put into the housing chamber.

Filed: 1991-02-08
Abstract: PURPOSE:To efficiently fractionate and purify an anti-viral activity substance from the aqueous extract of a cultured product obtained by culturing a shiitake (mushroom) fungus in a medium containing bagasse and rice bran. CONSTITUTION:The aqueous extract of a cultured product obtained by culturing a shiitake fungus in a medium containing bagasse and rice bran is subjected to an ultrafiltration using a tangential type device or a hollow fiber member- using device, and the filtrate is collected. The filtrate is preferably further subjected to a hydrophobic chromatography using as a carrier a cellulosic resin having octyl or phenyl groups as functional groups to extremely efficiently fractionate or purify an antiviral substance from the aqueous solution. The preliminary filtration of the aqueous extract using a 0.1-0.45mum thick ultrafiltration membrane permits to greatly improve the workability of the ultrafiltration. The active ingredient adsorbed on the hydrophobic resin can be eluted with water, while unnecessitating an operation for removing a solvent except water from the elution solution.

Title: Matrix of fuel cell with phosphoric acid
Inventor: ENOMOTO HIROBUMI
IPC: H01M8/02
Filed: 1993-03-02
Abstract: PURPOSE:To enhance the electrolyte retention, internal resistance, and mechanical strength of a phosphoric acid type fuel cell matrix. CONSTITUTION:Scale-form boron nitride 1 having a means particle size between 0.1-1.0mum is uniformly mixed with cubic crystalline boron nitride 3 having a means particle size between 1-10mum, each of which should be contained no less than an amount 1/3 of the total weight. while the remainder consists of PTFE 2 which serves for enhancing the mutual bond. With this matrix produced, the scale-form boron nitride having smaller particle size enhances the electrolyte retaining performance and enables embodying in thin film structure to lead to maintaining the internal resistance low, while the cubic crystalline boron nitride having larger particle size heightens the mechanical strength of the matrix in thin film form to ensure prevention of crack initiation. Thus the performance required of a matrix can be enhanced synthetically by combination of two types of boron nitrogen in different forms, and the characteristics of the resultant phosphoric acid type fuel cell are improved.

Abstract: PROBLEM TO BE SOLVED: To execute simple density control to shorten a density control time and to obtain a stable image with the same density before/after exchange by detecting a characteristic mark with a mark detecting means and providing a density setting control means for controlling set conditions for changing the image density. SOLUTION: The characteristic mark of an intermediate transfer body after exchange is detected by a mark detecting element and a signal on the detection value is transmitted to the mark detection value storage part 5a of the density setting control part 5 and stored. In a comparing part 5c, the mark detection value of the characteristic mark of the intermediate transfer body before exchange is taken out from a precious mark detection value storage part 5b and compared with the after being exchanged. Consequently, when a difference exists, it is judged that the intermediate transfer body after exchange is not the one before exchanged and the information is transmitted to a correction value predicting part 5d. This predicting part 5d predicts a correction value with respect to the set conditions and in a correction value setting part 5e, the correction value is set.  Further, the correction value is outputted to a fixed place by a correction value output part 5f.
