Patent JP-H05258580-A (JP)
Title: Nonvolatile semiconductor memory
IPC: G11C16/02
Filed: 1992-03-16
Abstract: PURPOSE:To prevent a penetrating current from a writing circuit to write verifying controller circuit by controlling to supply a second voltage to a word line after the writing circuit becomes inactive by the write verifying controller circuit. CONSTITUTION:At the time of writing, since a verifying signal is set on an L level and PGM signal is set on an H level, an nMOS transistor Tr 9 is turned on and a voltage required writing is supplied to the word line. Even if the verifying signal is changed to an H level in this state, nMOS Tr 17 keeps the OFF state since the write verifying control signal SC maintains the L level. When the PGM signal is changed to the L level and nMOS Tr 9 is turned off later, the write veryfying control signal SC becomes to the H level, nMOS Tr 17 is turned on and the voltage necessary for write verification is supplied to the word line. Thus, the nMOS Tr 9 and nMOS Tr 17 are prevented from turning on simultaneously by means of the write verifying controller 22.

Title: Mold for molding plastic and its production
Inventor: WATABE ROKURO
IPC: B29C33/38
Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To enhance the durability of a mold and the water repellency of the surface of the mold and to easily release a molded product by successively stacking chromium, silicon trioxide, silicon monoxide and polyfluoroethylene fibers on the substrate of the mold. SOLUTION: A chromium layer 2 with a thickness of 10-15nm, a silicon trioxide layer 3 with a thickness of 8-12nm, a silicon monoxide layer 4 with a thickness of 8-12nm and a layer with a thickness of 5-10nm of polyfluoroethylene fibers 5 are successively stacked on the cavity surface of a mold substrate 1 constituted of a ferrous material or nickel. When a mold is produced by a physical vapor deposition method, the mold substrate 1 is degreased and washed to be put in a vacuum tank and the vacuum tank is evacuated to successively stack the respective layers on the mold substrate by vapor deposition. The control of respective film thicknesses at this time is performed by a quartz vibrator in order to expect accuracy.  As a result, by forming polyfluoroethylene fibers 5 good in water repellency to the uppermost layer, a molded product can be easily released and the surface contamination thereof can be simply removed. Since these laminated layers are mutually good in close adhesiveness, the durability of the mold is enhanced.

Title: Method and device for granulating in fuidized bed
Inventor: OWAKI TAKAYUKI
IPC: B01J2/00
Filed: 1992-02-14
Abstract: PURPOSE:To uniformalize the particle diameter of granulated substance by raising the pressure-loss resistance of a dispersion plate in a granulator for a fluidized bed. CONSTITUTION:The pressure-loss resistance of a dispersion plate 4 in a granulator for a fluidized bed are raised. In other words, when the air quantity fed into the granulator for the fluidized bed is 2-6m<3>/min, the upper limit of the pressure-loss resistance of the dispersion plate 4 is regulated to the value exceeding 250-1800 pascal and the lower limit is regulated to the value exceeding 150-1000 pascal. As a concrete means for raising the pressure-loss resistance, a means for thickening the part of passing air in the dispersion plate and a means for diminishing the network of the dispersion plate are adopted. Further, as a simple method, such a means is adopted that at least two sheets of ordinary dispersion plate are overlapped and used. As a result, bubble diameter in the fluidized bed is diminished and granulation is uniformly performed in the fluidized bed.

Abstract: PURPOSE:To shorten a painting-out time by moving along the sides of a polygon, projecting the respective sides on X and Y axes, and deciding a convex polygon based on the number of times of changes in the moving direction on the axis. CONSTITUTION:A process move along a polygon 1 in the sequence of apexes P1, P2, P3,... PN, and P1, and the respective sides are projected on the X and Y axes. Next the number of times of changes in the moving direction of the sides projected on the X and Y axes is checked, when the number of times of the changes is, for example, <=2 for the both X axis and Y axis, the graphic is decided as the convex polygon in the painting-out processing.
