Title: Alumina dispersant and alumina dispersion
Inventor: KAWADA KENJI
IPC: C09D11/00
Filed: 1998-10-06
Abstract: PROBLEM TO BE SOLVED: To obtain a stable alumina dispersion excellent in dispersibility without causing flocculation by using an alumina dispersant based on a nitrogen- containing monocarboxylic acid such as nicotinic acid, picolinic acid, proline or glycine, alumina and an aqueous dispersive medium. SOLUTION: An alumina dispersant comprising 50-100% monocarboxylic acid containing at least one nitrogen atom in one molecule, an auxiliary dispersant, an oxycarboxylic acid, an inorganic acid, other organic acid, etc., is added to an aqueous dispersive medium containing about 10-60% alumina to obtain the objective stable alumina dispersion which does not cause thickening and the flocculation and precipitation or gelling of alumina. The nitrogen- containing monocarboxylic acid is preferably added by about 0.5-10 pts.wt. based on 100 pts.wt. alumina. The monocarboxylic acid is preferably an amino acid or a heterocyclic compound in which a carboxylic acid group bonds to a heterocycle containing a nitrogen atom as a hetero atom, in particular nicotinic acid or the like which is readily dissolved in an aqueous solvent and exhibits acidity or neutrality.

Title: Memory circulating application system
Inventor: KONDO YOICHI
IPC: G06F9/46
Filed: 1987-11-10
Abstract: PURPOSE:To extremely improve the reliability of the title system by using a means which shows where a section is busy or not, a means which selects an unused section and displaying the busy mode of said section, and a means which makes said unused section wait for a fixed time. CONSTITUTION:An individual part where an application display flag 12 of a data table 10 is kept turned off is researched at and after the head of the table 10. If all flags 12 are turned on under such conditions, the storage of new data is inhibited before a receiver side task 15 turns off the flags in a state where data are stored in all individual parts. Thus a transmitter side task 14 stops a program for a fixed period of time and researches the table 10 again at and after its head. When an individual part where the flag 12 is kept turned off is detected, the flag 12 is turned on. Then the data desiring the transmission of information is stored in a data storing part 13. Finally an area of a desired size is secured out of an inter-task information transmitting memory area and the individual part number 11 that set data is stored. Then the inter-task information is transmitted to the task 15.

Title: Flow control valve
Inventor: OKUMURA YOSHIHIKO
IPC: F16K11/072
Filed: 1996-10-29
Abstract: PROBLEM TO BE SOLVED: To suppress the generation of a poor sealing owing to the invasion of foreign matters such as a casting sand, as well as to suppress the generation of a water flowing sound in an area of a valve element where the opening area is relatively small. SOLUTION: The generation of a water flowing sound in an area of a valve element where the opening area is relatively small is resulting from a sudden contraction and a sudden curving of the flow of the warm water. Consequently, circular arc form parts are formed at the openings 171 and 17a at the warm water inlet side of the valve body 4a, as a passage form to reduce the sudden contraction and the sudden curving of the warm water flowing, to eleminate the edge of an opening edge, so as to suppress the generation of a water flowing sound. The circular arc form parts are formed also at a bypass side opening 172, and the outlet side openings 173 and 173a, to eliminate the edges of the opening edges, so as to suppress the damages of elastic seal parts 40 to 42, and the invasion of foreign matters.  As a result, sealing function by using the elastic seal parts 40 to 42 is secured for a long period.

Title: Superlattice structure of pbsnte crystal
Inventor: NISHIJIMA YOSHITO
IPC: H01S5/00
Filed: 1985-12-20
Abstract: PURPOSE:To improve implanted carrier confinement rate to a well layer by making the impurity density of a well layer lower than that of a barrier layer and making an impurity density in a region near a boundary to the well layer larger than that of a region separated from the boundary. CONSTITUTION:More impurity (e.g., Tl) than that of a well layer 1 is doped in a barrier layer 2, and much more impurity than a region 5 separated from a boundary of the layer 2 is doped in a region 4 near the boundary to the layer 1. A carrier density near the boundary 3 is increased by doping the more impurity than a region farther from the region, i.e., the center of the layer 2 on the region near the boundary from the layer 1, and diffused in the layer 1. Thus, a band bending effect in the layer 2 occurs strongly near the boundary 3, and is alleviated therein. Thus, a region which becomes lower Ec near the boundary in the layer 2 than that of the well layer, i.e., vacant level number is reduced, thereby increasing implanted carrier confinement rate to the well layer 1.

Abstract: PURPOSE:To reduce losses caused by fluid leakage from rotor blade ends and to improve the total system performance by providing a stationary part which is offset to the direction of the deflection by a distance equivalent to the rotor deflection onto the inside of a casing opposite to the rotor blade tips. CONSTITUTION:A stationary part opposite to the tip of blades 13 of a rotor 12 consists of a ring-shaped segment 14 which is assembled in a radially adjustable manner relative to a body part 11a of a casing 11. The tip clearance deltaL on the deflection side of the actual rotor and the tip clearance deltau on the opposite deflection side are set equal by offsetting this segment 14 to the deflection side by the deflection delta5 of the rotor 12. The upper clearance deltau of the rotor blade tip can be made smaller by the rotor deflection delta3 compared with the conventional arrangement. Losses caused by the fluid leakage from the rotor blade tip clearance are reduced compared with the conventional design, resulting in improvement of the performance at each turbine stage and improvement of the total system performance.
