Then, after a capacity electrode 2 and a gate electrode 3 have been formed using a double-layer polycrystalline Si technique, an N<+> ion is implanted into the substrate using a thick inter-layer film and the gate electrode 3 as a mask and the connected layer 9, with which the surface and the buried layer are connected, is formed by performing a heat treatment. As the surface of the substrate is not occupied by the wide bit line area, the capacity area can be enlarged with the same area of the cells and this enables to be resistive against the alpha rays. Also, a high integration can be obtained by reducing the area required for the bit line.

Title: Surface coated reduced iron and oxidation preventing method for the same
Inventor: KAWAI TAKAO
IPC: C23F15/00
Filed: 1995-03-23
Abstract: PURPOSE: To prevent the oxidation of a reduced iron as much as possible by covering the surface of reduced iron with a CO2 generating material. CONSTITUTION: The surface of the reduced iron is covered with the CO2 generating material to prevent the oxidation of the surface. The infiltration of oxygen or moisture is prevented by the covering and, if the oxidation occurs locally at the defect part of the covering, CO2 is generated by the heat of the oxidation reaction to suppress the oxidation. The CO2 generating material is a carbonate of at least one kind of metal selected from a group consisting of Ca, Mg and Mn. The covering of the CO2 generating material is formed by applying a solution, which contains the CO2 generating material or in which the CO2 generating material is dispersed, on the reduced iron and drying. As a result, the decomposed residual component is separated on molten metal surface as a slag.

The member 91 is laid over the supporting shafts 82a and 83a of the gear 82 and the moving gear 83 and turned with the supporting shaft 82a as center. The rotating end of the member 91 is energized upward by force f2 by a spring 92 functioning as an energizing member. When paper jamming occurs near the fixing device at the fixing time, a main motor is stopped. Thus, the moving gear 83 is moved upward by the energizing force of the spring 92 and separated from the driving gear 84. Therefore, the driving gear 84 driving the fixing device is separated from the driving system of a photoreceptor drum, etc., and the jammed paper is removed.

Title: Extinguishing agent and extinguishing device
Inventor: KAWAI KENJI
IPC: A62C35/13
Filed: 1991-03-28
Abstract: PURPOSE:To allow the transportation of the extinguishing agent without generating clogging in the mid-way of a piping for transportation and the ejection thereof onto a distant firing surface by constituting the extinguishing agent of spherical particles having an insulating characteristic without having hygroscopicity and setting the grain sizes thereof to prescribed grain sizes within a 0.5 to 3.0mm range. CONSTITUTION:The extinguishing agent S is constituted of the spherical particles and has the insulating characteristic without having hygroscopicity. This agent has nonreactivity with metals, such as sodium. Namely, the agent is constituted of ceramic materials and sand, etc., alone or combinations of plural kinds thereof. Fired ceramic grains are particularly preferably used. The ejection distance from a nozzle part 8 to the firing point is short if the grain sizes of the ceramic particles are small and an effect of shutting off the air degrades if the grain sizes are set too large. Thus, the grain size is preferably set to a prescribed size in the range of 0.5 to 3.0mm. The surfaces of the ceramic particles are formed smooth by lowering the coefft. of friction in order to assure the easier flow. The generation of the clogging in the midway of the piping 7 for transportation is prevented in this way.
