Abstract: The apparatus comprises a vessel to hold fiber to be dyed, the vessel being formed of a gas tight pressure resisting sealed construction and having a lid member to seal the vessel, the lid member being provided with a pressure control valve to control the internal pressure of the vessel, and the vessel being formed in cylindrical shape and being provided with a ring body integrally on its outer periphery; a flatcar for mounting the vessel which includes a pair of rotary shafts on an underframe, and the rotary shafts being rotatably connected to an output shaft of a geared motor by means of a chain, and the rotary shaft having a slip stop ring to position the rotary ring body of the vessel; and a microwave oscillating device having a radiation chamber connected to a microwave oscillator by means of a waveguide, and the internal pressure of the vessel being set at pressure above one atmosphere of pressure, and the microwaves are used to generate heat and the fiber is dyed by a boiling phenomenon at a boiling te

Abstract: Synthetic suede leather is produced by casting a mixture containing polyurethane elastomer and a solvent therefor between two sheets of a substrate fabric, immersing the resulting structure in a liquid which is a nonsolvent for polyurethane elastomer but miscible with said solvent, splitting said structure into two sheets at middle of the cast layer before it is fully gelled, and re-immersing the resultant sheets in said nonsolvent to allow complete gelation of said mixture.

Abstract: In a vehicle an alarm issues a warning signal just before actuation of an automatic emergency brake which operates in response to the relative speed and relative distance beween the vehicle and an obstacle in the vehicle's path.

Abstract: A rotary type hydraulic servo-mechanism constructed with a hollow-cylindrical casing, an input shaft extending through the casing, a driven output member slidably mounted on the casing, a servo-valve mechanism formed in the surface of the input shaft which slides on the driven output member, a hydraulic fluid chamber to generate a resisting torque against rotational force of the input shaft, and a passage to connect this hydraulic fluid chamber with the servo-valve mechanism, and hydraulic drive chambers defined by a space between the inner wall of the hollow cylindrical casing and the outer periphery of the driven output member.
