Title: Manufacture of composite oxide material for ferrite
Inventor: NOMURA TAKESHI
IPC: H01F1/34
Filed: 1992-12-24
Abstract: PURPOSE:To enhance the quality properties of a ferrite core by adding zinc oxide and manganese oxide or carbonate to an aqueous solution which contains ferric chloride, and spraying and calcinating this slurry. CONSTITUTION:Iron is added to 15 to 22% HCI aqueous solution obtained as hydrochloric acid pickling waste liquid for steel plates or the like and 50 to 100g/l iron chloride aqueous solution so that Fe ion equivalent amount in the aqueous solution may approach Cl<-> equivalent amount. Then, at least one type of manganese oxide or carbonate is injected into this aqueous solution so that the Fe:Mn ratio in the aqueous solution may be a specified amount ratio and controlled so that the metal ion equivalent amount in the aqueous solution may be virtually identical to the chlorine ion equivalent amount. Then, the slurry solution obtained by injecting Zn into the solution is sprayed into a spray calcinating operation so that it may be oxidized and calcinated. Microadditives are added to the thus obtained composite oxide powder and mixed and molded and then sintered at a high temperature in calcinating furnace. This construction makes it possible to obtain a composite oxide which minimizes the vaporization of P contents and zinc portions.

Title: Restriction adjusting device
Inventor: NOMURA YURIKO
IPC: G06N5/04
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To enable a system user to set an evaluated value in an easy-to- understand style by making the user specify restrictions from restriction information that a system shows and input qualitative data, and quantizing them and automatically correcting an evaluation expression. SOLUTION: A system engineer generates restrictions by using an evaluation framing write part 5 for system structuring. A restriction supplement device 3 is actuated to obtain an evaluated value. When the restrictions need to be adjusted as to the evaluated value, a system user inputs qualitative data regarding restriction adjustment by using a concrete example input part 8. Further, the data are quantized by using a data extraction part 9, and coefficients of the evaluation expression are determined by an approximate expression generation part 10 and written back to restriction information by using an evaluation expression generation part 11. Consequently, the system user need not understand the mechanism of evaluated value calculation in restriction inference and the contents of individual evaluation expressions.

Title: Energy absorption device
Inventor: KOJIMA NOBUYUKI
IPC: F16F9/30
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To obtain constant vibration energy absorptivity by forming projecting bodies projected at intervals in the axial direction and setting the ratio of height to a space in the mutually adjacent projecting bodies in a specified value or less. SOLUTION: A cylinder 2 is connected to one structure. A rod 3 is coupled with the other structure. When vibrations are generated between the rod 3 and the cylinder 2, lead 7 is fluidized plastically into space 6 between the outer circumferential surface 5 of the rod 3, to which projections 41 are formed, and the inner circumferential surface 4 of the cylinder 2, and vibration energy is absorbed by the displacement of lead 7. Since the plastic fluid of lead 7 is dispersed at that time, the absorption of vibration energy is also dispersed, and heat generation in the vicinity of the projections 41 is also dispersed. Consequently, plastic fluid resistance is not lowered by the temperature rise of lead 7. The ratio H/D of the height H of the mutualy adjacent projecting bodies to axial spaces D is set in 0.25 or less, preferably 0.2-0.25, more preferably 0.15-0.2 at that time.  Accordingly, constant energy absorptivity can be ensured during a time when vibrations are continued.

Title: Chemical treatment and device
Inventor: TAKANO MICHIAKI
IPC: G03F7/30
Filed: 1992-12-31
Abstract: PURPOSE:To apply simultaneously a chemical on the whole surface of a substrate to be treated and lessen an irregularity in the dimension of a pattern by a method wherein a flat nozzle provided with a multitude of discharge ports is made to approach the substrate or is brought into contact to the substrate to treat the substrate. CONSTITUTION:A mask 2 which is a substrate to be treated is horizontally placed on a stage 1 in such a way as to oppose to a flat nozzle 3. A chemical tank 4 is pressurized, a valve 5 is opened to discharge a developing solution MIBK through the nozzle 3 and the MIBK is applied on the mask 2 as shown in 6. An arm 12 on the nozzle 6 is coupled with a motor 14 by a coupling 13 and the nozzle 3 is vertically actuated by the rotation of the motor 14. The developing solution is applied through the discharge ports 8. As the MIBK, from which a void 10 is evaporated by making the nozzle 3 approach the MIBK 6 applied on a discharge surface 9 of the nozzle 3, is saturated, vaporization of the MIBK is inhibited and a temperature change is decreased. Accordingly, the evaporation loss of the MIBK is decreased compared with that at the time of the open valve. Thereby, a chemical can be simultaneously applied on the whole surface of the substrate.
