Title: Dynamic semiconductor storage device
Inventor: OTA MASAKO
IPC: G11C11/401
Filed: 1989-06-30
Abstract: PURPOSE:To highly integrate a DRAM without damaging high-speed performance by arranging and laying out a pair of select gate MOS transistors between a pair of bit lines in a bit line direction between a bit line sense amplifier and a memory cell array block. CONSTITUTION:A select gate MOS transistor Q11 composed of source and drain diffusing layers 11 and 12 and a gate electrode 13 is inserted on bit line BL and a select gate MOS transistor Q12 composed of source and drain diffusing layers 21 and 22 and a gate electrode 23 is inserted to another bit line -BL. These select gate MOS transistors Q11 and Q12 are arranged parallelly in the bit line direction and formed with gate width over the two bit lines. Thus, the gate width of the select gate MOS transistor can be made almost double and the pitch of the bit line can be reversely reduced further. Thus, a shared sense amplifier system DRAM can be highly integrated without damaging the high-speed performance.

Title: Tightly sealed pickle steeper
Inventor: INO SHIGEKO
IPC: A23L19/20
Filed: 1979-12-25
Abstract: PURPOSE: Pickle steepers are piled up by putting the bottom inside the shoulder of another steeper respectively and the pickle solution substituted by the osmotic pressure is automatically drained through holes on the wall of the inside steeper which connects to the bottom surface to prevent the occurrence of foreign microorganisms and insects and to reduce bad smells, thus preserving the pickles cleanly.  
     CONSTITUTION: An inner steeper 2 is removed from an outer steeper 1 and simultaneously a vessel 7 for a weight stone 2 is taken out of the inner steeper. A root vegetable is covered with salt and put into the outer steeper 1 and inner one 2. The inner steeper 2 is inserted from the shoulder of the outer steeper 1. Then, the vessel 7 for a weight stone 7 is put in the inner steeper 2 and a weight stone 11 is placed on the vessel 7. As the system is tightly sealed with a packing 3, the pickle solution leached out of the vegetables is not stained with film-forming yeasts and yeastlike moulds and the pickles in the outer steeper 1 and inner one 2 are preserved cleanly from hygienic point of view. When the root vegetables shrink and the inner steeper and the weight vessel 7 sink down, the pickle solution in each steeper is forced by pressure to pass through hole 6 and outlet 8 through hoses 9, 9' until it is expelled outside.

The reverse electrolytic treatment is further accomplished under the conditions under which the value of the ratio O/Cr<ox> between the area O corresponding to the oxygen in the oxide film and the peak area Cr<ox> corresponding to Cr attains <= 1.45. The ratio of the insoluble oxide film converted to an oxo-compound is increased and the soluble component in the oxide film is decreased before the electrolytic chromic acid treatment by the above-mentioned method and therefore the tin-free steel having excellent resistance to high temp. water is obtd.

Title: Dc brushless motor having core
Inventor: MIZUTANI MINORU
IPC: H02K29/08
Filed: 1990-06-28
Abstract: PURPOSE:To improve energy efficiency and to reduce manufacturing cost by integrally molding the housing sections of core and stator yoke of a composite material in which a resin is admixed with iron powder. CONSTITUTION:When a stator 10 is integrally formed, a composite material is prepared by admixing a resin material such as polyimide with iron powder. When the stator 10 is produced through molding, fixing error is eliminated from each part and the accuracy of the stator 10 depends only on the manufacturing accuracy of mold. Since a highly accurate mold can produce a highly accurate stator 10, fluctuation of rotation or torque can be eliminated positively. Furthermore, manufacturing cost can be reduced through integral molding. When the resistivity of core is increased, eddy current is suppressed and heating is prevented resulting in considerable improvement of energy efficiency.

Title: Production of bubble element
Inventor: SEGAWA MIKIO
IPC: G11C11/14
Filed: 1982-09-29
Abstract: PURPOSE:To avoid the damage and deformation of a pattern due to discharging by providing a pattern close to the pattern of the remote side via a small gap with which the discharge is easily generated and generating the discharge at the discharging pattern part during an after-process. CONSTITUTION:Patterns 81 and 82 which generate discharge are provided at positions close to the terminal and avoiding a gate part where conductor patterns Cb and C11 overlap a ''Permalloy '' pattern. That is, the pattern 81 extending to the side of the pattern C11 is unified from the side of the pattern Cb. While a pattern 91 extending to the side of the pattern Cb is unified from the side of the pattern C11. The space between both patterns 81 and 91 is reduced less than a gap with which the discharge is generated most easily between the patterns Cb and C11. Thus the discharge is generated at all times between those patterns 81 and 91 when the sputtering process is applied to an SiO2 layer.
