Title: Spraying material and spraying using the same
Inventor: ARAKI AKITOSHI
IPC: C04B28/02
Filed: 1997-01-08
Abstract: PROBLEM TO BE SOLVED: To improve reduction in water-reducing properties and dispersibility, change in slump value with time and workability of the spraying material by using a cement composition contg. cement, gypsum, and a calcium salt of a (polyoxyalkylene alkenyl ether)-(maleic anhydride) copolymer. SOLUTION: This spraying material is quick-setting concrete which is used for preventing bare ground from being collapsed and for which the above cement composition is used. In this cement composition, the gypsum is mixed with cement in order to provide the resulting cement mortal with high strength and, as the gypsum, anhydrous gypsum is preferred on account of its strength-developing properties. The gypsum is used preferably in an amount to provide a 5 to 20 pts.wt. ratio to 100 pts.wt. of the cement used, and the gypsum and cement are used in the form of the cement mortar which is a mixture consisting essentially of the gypsum and cement.  Also, the accelerating agent is a calcium aluminate quick-setting agent and desirably used in the form of a mixture obtained by adding a 50 to 150 pts.wt. of the gypsum to 100 pts.wt. of the accelerating agent, in order to improve the long-term strength of sprayed concrete. The salt of (polyalkylene alkenyl ether)-(maleic anhydride) copolymer is used in a 0.02 to 0.5 pts.wt. ratio to 100 pts.wt. of the cement used and contributes to improvement in flowability and slump loss of the cement mortar and reduction in amount of water in the mortar.

Title: Method and device for low-nox combustion
Inventor: OYATSU NORIYUKI
IPC: F23C99/00
Filed: 1993-01-07
Abstract: PURPOSE:To reduce the discharging amount of NOx at the outlet port of a furnace by reducing NOx, coming from an air port (AAP) for supplying the mixed gas of air and exhaust gas into a combustion furnace, in the furnace as much as possible. CONSTITUTION:The amount of air supplied into a primary combustion area through an air port 3 and the amount of air supplied into a secondary combustion area through another air port 4 are distributed so that the reducing rate of NOx, produced by a burner 2 or exhaust gas from the air port 3, is maximized in the primary combustion area of a furnace 1. The NOx, supplied into the primary combustion area, and the NOx, produced by combustion, are reacted in a reducing atmosphere since an air ratio in said combustion area is less than 1.0 whereby the NOx is reduced into harmless N2 gas. Further, the reduction area is secured by determining the ejecting direction of air ports in the primary combustion area and the secondary combustion area so as to restrain the mixing of gas so that combustion exhaust gas of the primary combustion area in the furnace 1 is not mixed with the combustion exhaust gas of the secondary combustion area as much as possible.

Title: C-mos analog switch
Inventor: OKITAKA YOSHINORI
IPC: H01L29/78
Filed: 1983-01-08
Abstract: PURPOSE:To suppress the back gate effect of a P-MOS or an N-MOS and to suppress variation in on resistance due to variation in input voltage by equalizing the substrate potentials of the P-channel and N-channel MOS transistors (TR) of a switch to an input voltage. CONSTITUTION:The substrate potentials of the P-MOS and N-MOS TRs are equalized to the input voltage. An analog switch turns on when a signal phi is at a low potential (VSS) on the circuit, and high impedance is obtained between an input IN and an output OUT when the signal phi is at a high potential (VDD) on the circuit to turn off the switch. Then, the substrate potentials of TRs N1 and N2 become equal to the input voltage when a TRP1 or the TRN2 turns on. Assuming the input to be a source, the potential difference between the sources of the TRs N1 and N2, and the source due to variation in input voltage is eliminated, and the TRs N1 and N2 suppress the back gate effect.

IPC: H01L21/66
Filed: 1986-01-08
Abstract: PURPOSE:To measure the size of a pattern formed by ion implanting by utilizing a variation in a secondary electron detection signal generated due to the difference of secondary electron emission efficiencies of an ion implanted region and a non-ion implanted region. CONSTITUTION:An electron beam 1 of 150Angstrom  of diameter by 1.0kV of accelerating voltage and 5pA of current is moved along a scanning line 3 to cross an ion implanting pattern 5. Secondary electrons 2 emitted from the emitting point of the beam 1 are detected. Then, since the secondary electron emission efficiency of the ion implanted portion is larger than that of the non-ion implanted portion, the secondary electron current amount to be detected increases. The maximum value of a secondary electron signal 6 is 100% and the minimum value is 0%. A threshold value 10 is set at the position of 80%, and the widths 7, 9 of the ion implanted portions and the width 8 of the non-ion implanted portion from the crossing point of the signal 6 are measured. Thus, the size of the pattern 5 is measured.

Abstract: PROBLEM TO BE SOLVED: To make a device strong against injection of hot electrons and reduce leakage current by providing the process where a surface irregularity of poly Si film is reduced with the polishing process after laser annealing. SOLUTION: An amorphous Si film is formed by 100nm or less on an insulating substrate 1, then it is annealed to provide a poly Si film 2. Then, the poly Si film 2 crystallized by laser annealing is polished to flatten its surface.

Then, the obtained poly Si film 2 is etched to form a desired island, with a poly Si film 2a, after polishing, formed. Thus, the electric field concentration on a poly Si surface is reduced by flattening the poly Si surface, making it strong against injection of hot electrons to a gate insulation film, so a leakage current is reduced for a TFT of high reliability.
