Title: Method of placing underwater concrete
Inventor: SUENAGA AKINORI
IPC: E02D15/06
Filed: 1984-01-31
Abstract: PURPOSE:To prevent deterioration in the strength of concrete, by a method wherein, after upper layer concrete is placed on an underwater bedrock, concrete is placed through the under part of the upper concrete layer to increase an amount of the concrete. CONSTITUTION:After upper layer concrete 4, which is mixed with the admixture of a non-ionic high molecular material having clay of about 40cps. is charged through a charge port 31 to fill a tremie 3 therewith, the valve of a discharge port 32 is opened to cause the upper layer concrete 4 to quietly flow out onto bedrock 1. Thereafter, the tremie 3 is lifted up little by little, and the upper layer concrete 4 is placed in a given thickness in forms 2 in a condition that the upper surface of the upper layer concrete 4 is held horizontally as much as possible. After driving concrete 5 is charged through the charge port 31 to fill the tremie 3 therewith, the discharge port 32 is opened to cause the driving concrete 5 to flow out therethrough.

Title: Production of tile
Inventor: TAMAOKI TOKUHITO
IPC: C04B18/10
Filed: 1989-01-24
Abstract: PURPOSE:To effectively utilize the resources and to produce natural stoneary(granite) tile by weight-mixing imitation stone consisting of coal ashes, etc., granulated to the prescribed grain size with a raw material of tile, molding and calcining the mixture. CONSTITUTION:Tile is produced by weight-mixing imitation stone (e.g. coal ashes are mixed with PVA and proper amount of water is added and the mixture is kneaded and the kneaded mixture is dried to form a rigid massive shape and then this is ground to obtain prescribed grain size) granulated to prescribed grain size with a raw material of tile (e.g. feldspar, 'GAIROME' clay and silica sand, etc., are blended at the prescribed ratio) consisting of plastic, nonplastic and fluxing materials and molding this mixture and calcining the molded body. By the above-mentioned method, grain size can be arbitrarily set in comparison with utilization of natural mica and also monotone of a spot pattern is eliminated and the produced tile can be approached to natural stone. Further sp. gr. of imitation stone for the raw material of tile is made low and therefore it is deposited in the vicinity of the surface layer of tile and thereby the amount of utilized imitation stone can be lowered. Furthermore since it can be uniformly mixed with the raw material, the tile product which bears comparison with strength and has fire resistance and weather resistance is produced at low cost.

Abstract: PURPOSE: To eliminate unbalance of a precharge level by making signal levels applied to respective MISFETs different when a digit line of a memory cell is precharged by using MISFETs.  
     CONSTITUTION: When precharging signals ϕ 1 ' and ϕ 2 ' are at the high level at time t 0  while Vϕ 2 '>Vϕ 1 ' and Vϕ 2 '>V cc , MISFETs Q 11 ' and Q 12 ', and Q 13 ' conduct and terminals N 11 ' and N 12 ' are charged up to Vϕ 1 '-VT (where VT is the threshold level of  Q 11 ', Q 12 ' and Q 13 ' and Vϕ 1 '-VT≤V cc ). As terminals N 11 ' and N 12 ' are  charged up to Vϕ'-VT, Q 11 ' and  Q 12 ' are turned off. Therefore, since Vϕ 2 '>Vϕ 1 ',  Q 13 ' stays conductive until N 11 ' and N 12 ' reach Vϕ 2 '-VT respectively. For this  purpose, setting Vϕ 2 ' and Vϕ 1 ' so that Vϕ 2 '-Vϕ 1 '>ΔVT eliminates the difference  in precharge level between N 11 ' and N 12 ' even if there is difference ΔVT in the  threshold level VT between Q 11 ' and Q 12 '.

Title: Paper feeder
Inventor: TANAKA EISUKE
IPC: B41J11/26
Filed: 1985-02-01
Abstract: PURPOSE:To enable a paper to be fed without generating jamming or the like, by a method wherein a pressing force exerted on a fanfold paper is released at least one time during one rotation of a platen roller to thereby set the paper into a free state and release the tension, in a recorder in which a fanfold paper is used. CONSTITUTION:When a fanfold paper is set in position and is fed by driving a stepping motor, a projected part 20a of a cam 20 is engaged to a projection 10a of an arm 10 one time in each rotation of the platen roller 1, whereby a pinch roller 8 is separated from the roller 1. At this time, the pressing force exerted on the fanfold paper 18 by the pinch roller 8 is released, so that the paper 18 is set into a free state according to the tension thereof. Accordingly, since the paper 18 is set into the free state even where an error is present in the synchronism between the roller 1 and a pin wheel 16 or an error in paper feeding quantity is generated due to thermal expansion of the roller 1, no irrational force is exerted on the paper, the paper is automatically set into a natural state, and is prevented from breakage at small holes or jamming.
