Title: Preparation of particulate polyvinyl alcohol
Inventor: OOISHI TSUKASA
IPC: C08F8/12
Filed: 1980-02-29
Abstract: PURPOSE: To make the particle diameter of PVA into a particle diameter with improved water dispersion, by dispersing a polyvinyl ester solution using a mixed solvent obtained by blending specific amounts of an alcohol and a given hydrocarbon as solvents into a liquid of a nonsolvent in particular state, followed by saponification.  
     CONSTITUTION: A polyvinyl ester is dissolved in a mixed solvent consisting of (A) 100pts.wt. alcohol or alcohol and methyl acetate and (B) 10W200pts.wt. 5W10C  hydrocarbon (hexene, etc.). The prepared solution of the polyvinyl ester in the  mixed solvent is dispersed into a nonsolvent liquid, e.g., liquid paraffin, etc. in a  particle state and saponified. The nonsolvent liquid has to be almost immiscible  with the solvent A and a liquid having a higher viscosity than that of the solvent B.  In spite of the enlarged particle diameter, practically no nonsolvent liquid is contained in the particles.

Title: Surface packaging type electromagnetic sounding body and its production
Inventor: KUWABARA MUTSUMI
IPC: H04R13/00
Filed: 1997-01-27
Abstract: PROBLEM TO BE SOLVED: To make it possible to surely package and fix a surface. packaging type electromagnetic sounding body to a printed circuit board by forming solder plating layers into the recessed parts formed at the cut end faces of electrodes for external connection of the terminals for surface packaging to widen soldering areas, thereby intensifying the solder fixing power to the printed circuit board. SOLUTION: The electrodes 4a to 7a for external connection of the surface packaging type electromagnetic sounding body 18 are fixed by soldering to the mother board, such as printed circuit board. In such a case, through-holes 17 are formed in, for example, the positions corresponding to the cutting surfaces of the electrodes 4a to 7a for external connection in order to form the recessed parts at the end faces of the electrodes 4a to 7a for external connection of the terminals for surface packaging. The solder plating layers 8 are formed on the inside surfaces of the through-holes 17 by cutting these through-holes 17 even if a press blanking and cutting stage is executed. Then, the surface areas for soldering are widened at the time of packaging the electrodes 4a to 7a for external connection by soldering to the mother board.  The solder is stuck to the inside surfaces of the through-holes 17 and the solder fixing power is intensified.

Title: Ferroelectric memory device
Inventor: TANAKA JUN
IPC: H01L21/8242
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of the ferroelectric film of a memory element of a structure, wherein the ferroelectric film is used as a capacitor insulating film by a method in which an organic film is used as an insulating film and a passivation film, which are formed on the upper part of a capacitor. SOLUTION: A ferroelectric layer 4 is used as a capacitor insulating film of a capacotpr 101 and at the same time, an organic film is used as an insulating film 6 and a surface protective film 8, which are formed in a process later than that of forming the layer 4. Since the internal stresses of the organic film can be made low and H atoms contained in polyimide molecules in the protective film are bonded strongly with other taoms, such as C atoms, by covalent bonds, hydrogen molecules and hydrogen atoms will not be generated from the polyimide molecules in the organic film after the organic film once is formed. Owing to this, hydrogen molecules and hydrogen atoms can be prevented from being generated from the films 6 and 8 and diffusing in the layer 4.  Moreover, since it is possible for the organic film to be formed by coating and annealing, the organic film can be formed at a low temperature and the thermal deterioration of the layer 4 can be prevented from occurring.

Title: Stochastic search system
Inventor: MARUYAMA TSUTOMU
IPC: G06F15/16
Filed: 1992-02-14
Abstract: PURPOSE:To more improve a speed acceleration factor through a parallel processing by excluding waiting in processings such as the exchange of partial resolutions or stochastic selection. CONSTITUTION:N pieces of arbitrary values are prepared, copied to a buffer and stored, and following processings are repeated to respective values Ai(1<=i<=N). The value Ai is stochastically changed. One of values in the buffer is stochastically selected, and one part of the value Ai is replaced with one part of the selected value. Next, the value Ai is evaluated and compared with the evaluated values of values stored in the buffer. When the evaluated value of the value Ai is relatively adverse, a value Bk having the much better evaluated value is selected out of values in the buffer with much higher porbability, and this value is defined as the new value Ai and stored in the buffer. At such a time, any sufficiently adverse value is stored as the evaluated value of the value Ai. The evaluated value of the value Bk in the buffer is decreased just for a fixed amount. When the evaluated value of the value Ai is relatively good, the value Ai is copied and stored in the buffer.
