Title: Rubber-based foam
Inventor: MATSUMOTO MITSUO
IPC: C08L23/16
Filed: 1999-12-01
Abstract: PROBLEM TO BE SOLVED: To develop a rubber-based foam hardly causing fogging on glass or the like by a volatile or sublimable substance at a high temperature without deteriorating sealing properties and the like. SOLUTION: The rubber-based foam comprises a vulcanized foam of a mixture comprising as ingredients at least an ethylene/propylene-based rubber, azodicarbonamide and a zinc-containing blowing auxiliary. The above mixture permits a vulcanization treatment at a lowered decomposition temperature of azodicarbonamide using the zinc-containing blowing auxiliary instead of a urea-based blowing agent and gives the rubber-based foam exhibiting high sealing properties owing to excellent cushioning properties and compression properties of the ethylene/propylene-based rubber foam and hardly generating contaminants by volatilization or sublimation or causing fogging even at a high temperature.

Title: Manufacture of dot wire and mold used therefor
Inventor: KUBOTA HIROSHI
IPC: B41J2/235
Filed: 1989-12-29
Abstract: PURPOSE:To prevent the occurrence of such a deformation of a tungsten wire as bending caused by the pressure of a resin by a method wherein a wire is inserted into two cavities through a runner to be molded. CONSTITUTION:A mold for insert-molding a dot wire is provided with a runner 3 and a gate 4 on the rear bent part of a needle part 6 made of a tungsten wire 2 bent in a U shape. A melt resin to flow into the mold is injected from the gate 4 and cooled to be set, whereby the tungsten wire 2 is securely fixed. Because the melt resin is made to flow into the mold in which the rear end of the wire is inserted through the runner, the pressure of the melt resin acts to the U-shaped tungsten wire in a balanced state. In this manner, such a deformation of a tungsten wire as bending to a head part never occurs. Since a single U-shaped tungsten wire 2 is inserted through a pair of cavities, the runner and the tungsten wire are cut after the completion of the injection and dwell of the resin.

Title: Relay iron core
Inventor: HORI MASAMI
IPC: H01H50/36
Filed: 1992-12-22
Abstract: PURPOSE:To provide a matching tolerance with a spring load and enhance magnetic characteristic.

Title: Method of measuring thickness of slug in hot state
Inventor: KAWASAKI YASUHIRO
IPC: B22D11/16
Filed: 1989-12-27
Abstract: PURPOSE:To continuously and statically measure the thickness of a slug by measuring the total height of molten steel and the slug within a container and the temperature of the molten steel, and obtaining the weight of the molten steel on the assumption that the total height is for the case where the steel in the container is totally melted. CONSTITUTION:A distance sensor 4 measures the height of an upper part of a slug 5 within a turn dish 2, and obtains the total height of a molten steel 6 and the slug 5 based on the measuring value and further the total volume S1 of the molten steel 6 and slug 5 from the total height. A temperature sensor 7 measures the temperature of the molten steel 6, and the density of the molten steel 6 based on the measuring temperature. The weight M1 on the assumption that the total height is obtained for the case where the steel is totally melted is obtained by multiplying the density with the volume S1. A weight sensor 8 measures the weight of the tundish 2 and obtains the total weight M'2 of the molten steel 6 and slug 5 by subtracting the known weight of the tundish 2 from the measured tare Mf2. The total weight M'2 is subtracted from the weight M1, the result of which is divided by a value S1 obtained by multiplying the difference of the density between the molten steel and slug with the lateral cross sectional area S of the tundish 2, whereby the thickness of the slug is obtained.

Title: Thermally-actuated steam trap
Inventor: YUMOTO HIDEAKI
IPC: F16T1/10
Filed: 1993-12-21
Abstract: PURPOSE:To enable intermittent opening/closing valve operation and suppress the wear of a valve and a valve seat without mistaking the discharge of condensate for the leakage of steam at the time of discharging condensate by providing an orifice, smaller in opening area than a valve port, downstream of the valve port in a lead-out passage. CONSTITUTION:In the case of a low temperature fluid flowing in from an inlet 2, an expansion medium filled in a storage chamber 20 partitioned between an upper wall member 18 and a diaphragm 21 in a temperature control element 16 is contracted, so that the diaphragm 21 is displaced upward, and a valve member 23 is separated from a valve seat 9 to open a valve port 10. Low temperature condensate and air from the inlet 2 are thereby discharged to an outlet from a lead-out passage 8. At this valve opening time, pressure in the valve port 10 becomes high pressure close to the pressure on the inlet 2 side by the action of an orifice 12, formed into smaller diameter than the valve hole 10, between the valve port 10 and a through hole 11, so as to increase the force of energizing the valve member 23 in the opening direction by fluid pressure. In the case of a high temperature fluid flowing in, the valve member 23 is seated on the valve seat 9 to prevent the leakage of steam.
