Title: Operation of rotary kiln for reduction roasting iron and steel dust
Inventor: TSUZUKI KOJI
IPC: F27B7/42
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To stably recover Zn which further efficiently adds carbonaceous material, lowers Zn level remained in reduced iron pellet and restrains this variation, by changing adding ratio to iron and steel dust according to reactivity of the carbonaceous reducing agent. SOLUTION: The reactivity at 1000 deg.C quickly increasing reaction speed of the reaction, of cake as the carbonaceous material according to a reactivity test of solution loss reaction of the coke with JIS-K2151, the reactivity at 1000 deg.C radially is evaluated. Therein, the reactivity is defined as gasified C quantity per one hr, i.e., a coefficient of active reaction of the coke and shown with the equation. Since the reactivity of the coke is intensely dependent on grain diameter, it is desirable to grade the grain diameter as much as possible. The adding quantity of carbonaceous material is decided so that the C equivalent to metallize Fe2 O3 and ZnO becomes 1.0-1.5 times of the C equivalent obtd. by defining as the total fixed carbon quantity/the coefficient of effective reaction = the actual effective C quantity.

Title: Capacitive type sensor having linear responsiveness and method of obtaining linear responsiveness
Inventor: DANIERU EICHI GURANSAMU
IPC: H01L29/84
Filed: 1990-02-28
Abstract: PURPOSE: To provide a capacitive type sensor whose center part is displaced linearly while held in a plane shape by providing a hinge outside a diaphragm and surrounding the center part, and making the hinge thinner than the center part. CONSTITUTION: The hinge 311A is arranged in the circumferential direction nearby the outer peripheral edge of the Si diaphragm 311. The thickness of the center part of the diaphragm 311 is so selected that no curvature deformation is caused with load pressure within the constant measurement range of a pressure sensor 300 and the thickness of the hinge 311A, on the other hand, is so selected that curvature deformation is caused with the load pressure. For example, a pressure sensor 311 of 0 to 50 psi in pressure has a 0.19 inch external diameter, a 0.025 inch center thickness, a 0.02 inch hinge width, and a 0.003 inch thickness. With this constitution, the hinge 311A deforms by variation in the load pressure and the center part of the diaphragm is displaced linearly while held plane.  The displacement of the center is proportional to the load and the electrostatic capacity is in inverse proportion to the distance between the diaphragm and a substrate 312, so the output response of the sensor is represented as a linear function to loaded physical operation.

Title: Production of foamed synthetic resin
Inventor: KAIHARA KAZUTOSHI
IPC: C08J9/12
Filed: 1979-04-24
Abstract: PURPOSE: "Halon"  gas with high chemical extinguishing effect is used as a foaming agent for synthetic resins to fill the foams with the halon gas, thus increasing fire-resistant and fire-proofing properties of the resins.  
     CONSTITUTION: "Halon" gas, a kind of halgenated hydrocarbon containing bromine atoms and boiling at low temperatures, such as CF 3 Br, alone or a mixture thereof with another foaming agent such as Flon gas is used as a foaming agent for combustible foamed synthetic resins to produce the objective resin having negative catalytic effect on burning. The concentration of the "Halon" gas is 5% based on the air in the room. "Halon" gas is thermally decomposed during the chain reaction of burning to form bromine radical, which combines with hydrogen radicals acting as the chain reaction factor to stop the chain reactions and extinguish the fire. The  resulting hydrogen bromide combines with another chain reaction factor (i.e.  hydroxyl rodical), to regenerate bromine radical, which repeats to extinguish fire.

Title: Method for injection compression molding
Inventor: KAYAHARA TOSHIHIRO
IPC: B29C45/56
Filed: 1997-03-05
Abstract: PROBLEM TO BE SOLVED: To prevent a burr from generating and suppress the thermal shrinkage due to short resin amount by a method wherein an injection comes to an end when the injection amount, which is just enough for molding a molded article, is metered and, at the same time, a gate is brought to a clogged state. SOLUTION: When an injection amount, which is just enough for molding, is metered, the injection of a melted resin is brought to an end. At the same time, by actuating a gate cut 16, a gate is shut off. After that, by actuating a pressurizing means, a core mold 11 is displaced upwards so as to reduce a cavity, which is formed thicker than an optical disk, to a mold clamping direction in order to compression-mold a resin in the cavity. Thus, the uniformalization of molecular orientation is contrived and, at the same time, the transfer factor of information from a stamper 5 is also improved. No burr due to the efflux of melted resin from the cavity develops.
