Abstract: PURPOSE: To enhance reliability in memory function by making output voltage for driving a memory word line about 2Vdd in DRAM. CONSTITUTION: Capacity 15 is charged to Vdd-Vth in the initialization of actuation through N type FET diode 16. In observing the switching circuit and the waveform of clock ϕ of capacity 27 on the left side of the diode 16, FET 23, 25 are turned on when ϕ1 and ϕ1 <+> are 'H', with the capacity 27 charged to Vdd. Then, FET 23, 25 are turned off at the end of ϕ1 . After a discontinuous time, ϕ2 and ϕ2 <+> become 'L', with FET 24, 26 turned on. The terminal of capacity once connected to Vdd is connected to an output terminal 19, with the negative terminal of the capacity connected to Vdd. If the capacity 15 is 0V, the voltage grounded at the terminal 19 is 2Vdd in which Vdd for ground is added to the initial voltage of the capacity 27.  However, the capacity 15 having a large value, with the value of the capacity 15, 27 made CR, CS, a node 19 is provided with a voltage of [CS/(CS+CR)] (2Vdd-Vpp). Thus, the pump attains a maximum level 2Vdd.

Title: Method and apparatus for shaping refrigerated mold
Inventor: NAKASHIMA JIYUNSAKU
IPC: B22C9/02
Filed: 1978-06-17
Abstract: PURPOSE:To shape the mold in a short time, and to prevent the generation of collapse of the  mold at rapping operation, by filling the precooled molding sand into the pattern while applying  moisture to the surface of the sand particles. CONSTITUTION:The first valve hole 7 is closed by the valve body 9, and twice or more times of  the amount of molding sand S for one process are charged into the primary cooling room 2. The  second valve hole 11 is closed by the valve body 12, and the cooling medium R is horizontally,  radially injected from the cooling nozzle 14.

Next, by lifting the valve body 9, the sand S falls down into the secondary cooling room 3, and is  formed into a cylindrical thin curtain by the guide cone 13, and is cooled so far as its core by the  cooling medium R. After the desired amount of the sand S is accumulated in the room 3, the  supply of the colling medium R is stopped, the valve hole 7 is closed, and the valve hole 11 is opened. The moisture W being injected just under the guide cone 18 of the moisture supply room  4, is applied to the surface of the sand S; after that, the sand S is filled into the pattern through  the sand discharge port 17. At this point, the moisture on the surface of the sand S freezes, so  that the sand S automatically solidifies within the pattern.

Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To provide an image forming material being suitable for a lithographic printing plate, which is excellent in image forming properties (a sensitivity, a development latitude). SOLUTION: This image forming material contains a polymer binder which is water-insoluble and soluble with an alkali aqueous solution, and an infrared ray absorber having a thermally decomposable sulfonate group. At unexposed parts, the infrared absorber having the thermally decomposable sulfonate group reduces the melting speed of an alkali-soluble polymer binder, and at exposed parts, a sulfonic acid of a coloring matter which is generated by a decomposition of the infrared ray absorber, increases the melting speed of the alkali- soluble polymer binder. By this method, a difference between both parts becomes larger, and a favorable image formation becomes possible.

Title: Method for preventing corrosion of metallic material
Inventor: NAKAHARA MASAHIRO
IPC: C23F11/18
Filed: 1983-04-28
Abstract: PURPOSE:To prevent the corrosion of a metallic material due to a non-oxidizing acid when the metallic material which is passivated with an oxidizing acid is brought into contact with the nonoxidizing acid, by adding a heteropolyacid to the nonoxidizing acid. CONSTITUTION:A metallic material which is passivated with an oxidizing acid, e.g., stainless steel is extremely corroded when it contacts a nonoxidizing acid such as dil. sulfuric acid or formic acid. The corrosion of stainless steel due to the nonoxidizing acid is prevented by adding a small amount of a heteropolyacid such as phosphomolybdic acid as an oxidizing acid to the nonoxidizing acid. Accordingly, inexpensive stainless steel can be used as the material of a vessel for a nonoxidizing acid.
