Title: Horizontal type cyclone
Inventor: YOKOOOJI MAKOTO
IPC: B04C3/00
Filed: 1982-01-12
Abstract: PURPOSE:To provide a horizontal type cyclone which has high dust collection efficiency and small pressure drop, by the constitution wherein an inlet duct for dusty gas is provided to the end face in the small diameter part of a hollow cylindrical body of a truncated circular cone shape having a horizontal shaft, and a dust collection channel and a gas discharge dust are provided in the large diameter part, respectively. CONSTITUTION:A dusty gas is introduced into a cylindrical cyclone body 1 assuming a hollow truncated circular cone shape having a turning shaft in a horizontal direction through an inlet duct 3 for dusty gas connected to the end face 2 in the small diameter part of said body 1 in the direction tangential thereto. While the gas swirls along the inside wall of the body 1, and advances toward an end face 4 in the large diameter part, whereby the dust is separated. The gas is discharged through the end face 4 and through a gas discharging dust 7 connected to a suction port 8 for waste gas projected in the body 1. The dust is discharged from a discharge chute 6 for dust through a dust collection channel 5 of an inverted triangular shape which touches externally the end face 4. Since the flow of the gas in the body 1 is made circular and unidirectional, the efficiency of dust collection is improved and the pressure drop is decreased.

Title: Treating method of permanent mold
Inventor: SUGITANI JIYUNICHI
IPC: B22C23/02
Filed: 1979-01-12
Abstract: PURPOSE: To obtain the cast pipe free from shrinkage cavities in the inside surface by coating refractory slurry on the inside surface of the preheated permanent mold, drying the same through vacuum degassing then further sealing inert gas in the mold and performing pouring of molten metal.  
     CONSTITUTION: While the preheated permanent mold is being rotated, slurry-form refractory coating liquid is coated through a coat injection nozzle which makes reciprocating motion in the axial direction. When the film of the specified thickness is formed, the mold is put in a vacuum box and is degassed for 20W60min in a vacuum of about 1W10 Torr to allow the moisture and volatile component interposing in the film inside surface to evaporate and desorb. Thence, inert gas such as Ar gas is gradually injected into the box to restore the atmospheric pressure in the box inside, in which state the mold is taken out from the box. This treatment makes it possible to prevent the phenomenon of producing shrinkage cavities owing to oozing of the volatile components on the inside surface of the casting when molten metal is poured into the rotary mold.

Title: Electromagnetic type fuel injection valve
Inventor: TAKAHASHI IKUO
IPC: F02M61/18
Filed: 1986-01-13
Abstract: PURPOSE:To reduce the variation of the injection quantity due to the negative pressure by forming a recirculation flow feeding port which communicates to the contact electrode side on the outer peripheral surface of a ball valve body onto the inner peripheral surface of a guide hole on a nozzle body, thus suppressing the influence of the foams for the valve closing response time. CONSTITUTION:On the inner peripheral surface of a guide hole 10 on a nozzle body 9, a fuel feeding port 19 is opened at the position between the outer peripheral part 16 of a valve body 15 and a valve seat 14 and a recirculation flow feeding port 20 is opened on a contact electrode 8 side. The recirculation flow feeding port 20 is formed along the tangential direction to the inner peripheral circle of the guide hole 10 and in the same direction to the fuel turning direction. A portion of the fuel supplied from the fuel feeding port 19 passes through the longitudinal groove 18 of the ball valve body 15 and is recirculated to a pressurized fuel feeding source with the fuel which performs the turning movement at the recirculation flow feeding port 20 from a fuel return port 23 and a fuel discharge conduit 24. The sufficient recirculation is generated in the vicinity of the valve seat 14 because of the formation of the recirculation flow feeding port 20, and since the foams which grow as the increase of the negative pressure can be released, the influence of the foams for the valve closing response time is reduced.
