Title: Scroll gas compressor provided with check valve gear for differential pressure oiling
Inventor: FUJIO KATSUHARU
IPC: F04C27/00
Filed: 1987-07-27
Abstract: PURPOSE:To improve the extent of compression efficiency by opening or closing an oil feed passage between an oil sump and an inlet chamber by means of a check valve gear in the midway of an injection passage lying between a discharge chamber and a compression space. CONSTITUTION:An interval between a first compression space 39b and an oil sump 18 is interconnected by an injection passage consisting of an oil suction hole, a non-return valve gear 17, a punched groove 45 and an injection hole 30b. An interval between the oil sump 18 and an inlet chamber 33 comes to a lubrication passage leading to bearing 49, 51 by way of an oil hole 46. A reed valve 53 of the non-return valve gear 17 and a reed valve 54 of a check valve 16 both are formed after punching a part of a valve plate. Consequently, the non-return valve gear comes to double as an on-off valve for the oil feed passage, thus space saving is well promotable.

Title: Rolling method by edger
Inventor: KOKUBO ICHIRO
IPC: B21B13/06
Filed: 1984-09-05
Abstract: PURPOSE:To prevent the buckling of a rolling material by restraining the increase of its deformation due to edging, and to increase the rolling reduction in the width direction, by biting the material to vertical rolls while producing its deformation by slightly raising its both ends as well as supporting its central part by a roll table, in rolling a material by using an edger. CONSTITUTION:A pair of vertical rolls 3 is vertically installed at both sides of a roll table 2 used for conveying a rolling material S; and the lower end of a slant part 5 of roll 3, formed by continuously unifying a lower-side flange 4 and the slant part 5, is positioned on the same level as that of the pass line of material S or on the level of the lower side of material S. Therefore, the lower edges of both side ends of material S collide against the parts 5 during rolling, and said both side ends are raised to the small-diam. parts of parts 5 to deform the material S into a downward projecting form. This deformation tends to increase when the material S' is edged in this state, but the increase of this deformation is restrained and the deflection of material S' is limited because the central part of material S' is supported by the table 2.
