Title: Production of glauber's salt
Inventor: SHINOZUKA KIYOSHI
IPC: C01B7/03
Filed: 1985-04-26
Abstract: PURPOSE:To produce economically Glauber's salt, by crystallizing the Glauber's salt from iron sulfate and inexpensive rock salt or industrial salt as a raw material utilizing the solubility difference at the temperature of the Glauber's salt without using the crystallization step of the Glauber's salt depending on concentration of a Glauber's salt solution. CONSTITUTION:Iron sulfate is mixed or granulated with sodium chloride, and the granulated material is then roasted at >=400 deg.C in the presence of oxygen and steam to give a roasted material consisting essentially of iron oxide and Glauber's salt. The roasted material (A) from a roasting furnace 1 is cooled in a cooler 2, and then charged into a leaching tank 3. The Glauber's salt in the roasted material is dissolved in a separating solution cooled in a cooler 9 and additional water (B) to form a Glauber's salt solution slurry of iron oxide. The leaching tank 3 is kept at 33-35 deg.C at which the solubility of the Glauber's salt is highest. The iron oxide (C) is then separated from the above-mentioned slurry in a filter 4. The formed Glauber's salt mother liquor (D) is fed to heaters 5 and 6 and heated at 60 deg.C to crystallize the Glauber's salt. The complete deposition of crystals and concentration are carried out in a crystallization tank 7 to separate the crystals in a separator 8. The separated solution (F) of the crystallization tank 7 and separated solution (G) of the separator 8 are subjected to heat exchange with the mother liquor (D) in the heater 5 passed through the cooler 9 and then returned to the leaching tank 3.

Filed: 1993-03-25
Abstract: PURPOSE:To project a seal shape material from a panel main body and prevent the generation of a big impact sound when the seal shape material is collided against the surface of a ceiling by installing a buffering device which reduces a projection speed of the panel main body of a movable partitioning device. CONSTITUTION:When moving a panel main body, at first, a seal shape material, which operates housing drive mechanism 52, 38 and 46 with a steering handle, is housed in a panel main body. In this state, the seal shape material is held in a housing state. Stopper mechanisms 53, 62a and 64 hold the seal shape material in this housing state and move the panel main body to a desired position in this state.

Title: Steering device for vehicle
Inventor: NEZU KOUTA
IPC: B62K21/00
Filed: 1991-01-29
Abstract: PURPOSE:To permit the steering even in the case where a driver drives a vehicle at the low attitude of center of gravity by allowing an elastic plate to be tension-deformed in the lateral direction by the force generated in the axle direction of a steered wheel by tilting a car body frame in the lateral direction and allowing the steered wheel to be steered by the generated longitudinal difference on a revolution shaft. CONSTITUTION:When a driver D shifts the center of gravity during traveling and tilts a car body frame F leftward, the force Pc of component of the resistance force Pa acts in the axle direction of a steered wheel W from the ground surface. Though a wheel frame Fw tends to be pushed out to the right outside from the center of the car body, an elalstic plate 1 is torsion-deformed so as to intrude to the rear part from the center of the car body, since the revolution shafts 2 and 2' are restrained in turnable manner by the outer pipes 3 and 3' fixed at the front edge parts of the elastic plates 1 and 1', and the elastic plate 1' is torsion-deformed so as to extend towards the outside front part of the car body. Accordingly, a longitudinal difference is generated on the revolution shafts 2 and 2', and the wheel frame Fw is steered leftward, and the steered wheel W is steered leftward.

Abstract: PURPOSE:To continuously cast an ingot without central segregation by specifying an ingot size, setting the final solidifying position of the ingot at the level higher than the molten steel level in a casting mold and recuperating the final solidifying part to>=1250 deg.C. CONSTITUTION:The molten steel from a ladle 1 is poured into the casting mold 4 and is formed to a solidified shell 7 by an ingot guiding device 5. The ingot is continuously drawn through a holding furnace 8. The ingot size in this stage is specified to>=4 L/t and<=200 t when the width is designated as Lmm and the thickness as tmm. A crater end (solidifying end) 9 is positioned upper than the molten steel level in the casting mold and the surface of the final solidifying part is reheated to 1250 deg.C in the holding furnace 8. The suction flow of the thickened molten steel and the body bulging of the ingot by the static pressure of the molten steel are thereby prevented and the central segregation is prevented. The shrinkage cavities on solidification, etc., by reheating are eliminated and the continuous casting of the ingot is executed.
