Filed: 1996-07-30
Abstract: PROBLEM TO BE SOLVED: To increase the freedom in layout by covering the top of the first wiring layer buried in the groove made in an insulating layer with insulating material of different kind from the insulating layer, as a cap insulator, and arranging a second wiring layer on the cap insulator. SOLUTION: A groove 18 to form buried wiring is made in an insulating layer 2. Next, after exfoliation of resist 17, a polycrystalline silicon film doped with a large quantity of phosphorous impurities is accumulated as the first conductor film all over the surface. Next, the whole face is etched back by anisotropic dry etching, and etch back is performed in such a way that the polycrystalline silicon film remains within the groove 18 so as form buried pit wires 3 and 3a in the groove 18. Next, a silicon oxynitride film is accumulated all over the face as the second insulating film so as to form an insulating film 19 for a cap. Then, the groove 19 wherein the buried bit wires 3 and 3a are buried is filled up completely with an insulating film 19 for a cap. Hereby, the formation of the insulating film to insulate the buried wiring from the silicon substrate 1 becomes needless.

Filed: 1995-08-07
Abstract: PROBLEM TO BE SOLVED: To eliminate delayed control and increase following property when the height of a fluidized bed is reduced upon reducing a load. SOLUTION: The height of the layer of a pressurized fluidized bed combustion device is controlled upon reducing the load thereof by a method wherein the amount of transfer of fluidized medium, transferred from the pressurized fluidized bed furnace into a pressurized fluidized medium vessel, is controlled by a flow rate regulating valve of air for fluidizing and transporting and a pressure reduction regulating valve 21, provided at the air outlet port of the pressurized fluidized medium vessel, to lower the height of the fluidized bed of the pressurized fluidized bed furnace.  In such a method, the pressure reduction regulating valve 21, provided at the air outlet port of the pressurized fluidized medium vessel, is opened and closed in accordance with a difference between the objective fluidized bed height of the pressurized fluidized bed furnace and a detected layer height signal 35 or a layer height difference 36.

Title: Gas laser generator
Inventor: MERA KAZUO
IPC: H01S3/139
Filed: 1983-10-28
Abstract: PURPOSE:To suppress the variation at the output mirror side of a generator body by providing position suppressing means between the optical supporting plate of the output side and the body. CONSTITUTION:While an oscillator body 1 is operating, an internal temperature rises by a glow discharge 5 between electrodes, and the body 1 particularly extends in a direction of a laser optical axis 13. Thus, a slide roller 17A moves in directions of both optical supporting plates 11A, 11B along the interior of V-shaped groove 16, but the movement of the slide roller 17A at the output mirror 10 side is prevented by the position suppressing lever 22. When small output is used from this state, the inner temperature in the body 1 decreases to contract, but the movement is stopped by a position suppressing lever 22 at this time. This is similar in case that the body 1 elongates or contracts in lateral direction of the flowing direction of mixture gas flow 7, the movement of the direction of the optical axis 13 is stopped, thereby reducing the variation in the position of the mirror 10.

Title: Production of polysaccharide
Inventor: ITOU HAJIME
IPC: C08B37/12
Filed: 1981-12-15
Abstract: PURPOSE:To effect efficient and smooth production of a polysaccharide from its solution with the aid of a hydrophilic organic solvent and, to enhance the efficiency of purification and dewatering of polysaccharide. CONSTITUTION:In the first stage, a hydrophilic organic solvent (e.g. isopropyl alcohol) is added to an aqueous polysaccharide solution agitated under high shear conditions in an amount corresponding to 50-80% of the amount necessary to precipitate the polysaccharide (e.g., carrageenan, furcellaran, agar). Thus, there is obtained a uniform solution of a polysaccharide in a mixed solvent  containing the hydrophilic organic solvent and water. This makes it possible to avoid disadvantages, such as formation of crumbs due to non-uniformity of the  system caused by the addition of a water-soluble organic solvent in the subsequent stage. Then, in the second stage, the above solvent is added to said solution, with agitation, so as to provide the amount of the hydrophilic organic solvent necessary to precipitate the polysaccharide. In this state, the polysaccharide begins precipitation and it can predipitate in a very uniform manner because of an extremely slow change in solvent composition.

Title: Hydraulic elevator
Inventor: KOBAYASHI SEI
IPC: B66B1/26
Filed: 1989-08-02
Abstract: PURPOSE:To reduce a neutral zone in the vicinity of zero with a flow of fluid in a flowmeter in a fixed direction by arranging the flowmeter between a flow control valve and a fluid pressure generating device and controlling a speed signal, for a riding cage to run, and an output signal of the flowmeter. CONSTITUTION:In a control device 22, a flow control valve 6 is controlled by a speed command and an output of a flowmeter 20. Here, in up-running, because the speed command and the output of the flowmeter 20 are provided with a reverse pattern, a delivery amount from a fluid pressure pump 18 is subtracted from a flow signal of the flowmeter 20 with positive-negative inverted and fed back, and the control valve 6 is controlled by a deviation signal from the speed signal with a cage 2 up lifted by a fluid pressure cylinder 4. While at the time of down-operation, similarly a flow control valve 10 is controlled. Thus, a flow of fluid in the flowmeter is in a fixed direction possible to compensate an influence of a neutral zone in the vicinity of zero further to shorten a start delay.

Filed: 1982-11-16
Abstract: PURPOSE:To form a rolled steel plate having different widths wherein the width of the narrow part of a final rolled material is the same as the width of a slab at a good yield by changing a rolling reduction during forming and rolling pass to form the rolled material regulated of a difference in wall thickness in the rolling direction, turning 90 deg. the rolled material and subjecting the material to cross rolling then to finish rolling. CONSTITUTION:A difference in thickness (DELTAt+DELTAt') is given in the rolling direction, as shown in the figure, in a forming and rolling stage for a thick steel plate whereby a rolled material A is formed. The material A is turned 90 deg. and is rolled down only in the thick walled part in a cross rolling stage, whereby a rolled material B having a prescribed width W1 (the same width as the width of the slab) and W2 (the width larger than the width of the slab) is obtd. The material A is rolled down in the difference DELTAT in thickness larger by DELTAt' than the difference DELTAT necessary for the rate of changing the width. Therefore even if the actual rolling load is smaller than the predicted value, the thin walled part is not rolled down and is maintained at the slab width. The material B is again turned 90 deg. and is rolled down to a required thickness in a finish rolling stage, whereby a final rolled material C is obtd.
