Title: Recovering device of water surface floating oil mass
Inventor: ISHIDA MICHIHIKO
IPC: E02B15/10
Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To take a floating oil mass to the inner part and facilitate the recovery by installing a recovering bag within a bucket having an oil suction port, and arranging a draining screw within a drain port, and holding the bucket upper part by a float in the state floating on the water surface. SOLUTION: When a bucket 2 is lowered from a working vessel to the floating position of an oil mass O with a recovering shoot 5 being turned thereto, water is penetrated from a drain port 4 to submerge the bucket 2, and the upper part from a float 14 is exposed and floated on the sea surface. The oil mass O containing sea water is sucked into the bucket 2 by the water flow heading for the bucket 2 inner part from the recovering shoot 5, and only the oil mass O is accumulated in a recovering bag 9. When the recovering bag 9 is filled with the oil mass O, the bucket 2 is lifted up onto the working vessel, a ring 12 is released, and the oil mass O is housed in an exclusive vessel together with the recovering bag 9. Further, a new recovering bag 9 is installed to the bucket 2 to perform the recovering work again.  Thus, the oil mass O is sucked into the bucket 2, and accumulated in the recovering bag 9, whereby the recovering can be easily repeated.

Title: Commutator device of rotary electrical machine
Inventor: SONOBE TADASHI
IPC: H01R39/32
Filed: 1979-04-09
Abstract: PURPOSE: To decrease the vibration stress occurring from risers by tight binding the adjacent two risers alternately with an insulated tight binding material so that the spacing between the adjacent risers is lesened, and by forming almost deltoid spaces on both sides of the tight binding material.  
     CONSTITUTION: The commutator risers 30 adjoining each other are tight bound alternately with a tright binding material 40 almost at the central point of longitudinal direction. In this case, an insulating spacer 14, having the smaller thickness than the adjoining riser spacing P, is inserted between the risers to be bound, and the two risers are firmly bound so that the thickness of them bicomes smaller than the spacing P, thereby forming deltoid spaces ga and gb on the upper and the lower sides of the boundary line placed at the bound section. In case an inertia force F (t) acts on the risers 30, reaction forces R and Ra are generated due to the effect of truss to the risers, thereby generating a reaction force R6 at the base of the risers. Due to the above reaction force, together with the micro elastic displacement at this section, a damping effect arising from the disappearance of energy, appears at the base of the risers. Therefore, the vibration stress is decreased and the reliability of the machanical strength can be raised.

Filed: 1987-02-24
Abstract: PURPOSE:To vapor-deposit high hardness films of a metallic carbide or nitride on the cutting edges of many cutting tools made of a metal with superior productivity in a high yield of starting materials, by piling up the edged tools so that the cutting edges are lined up and by treating the cutting edges. CONSTITUTION:Many cutting tools 3 are piled up at regular intervals through spacer 7 so that the cutting edges 31 are lined up, the piled-up cutting tools 3 are fitted to a holder 4 in a vacuum vessel 1 and a cathode 2 is fixed on the holder 4. The vessel 1 is evacuated and vapor of a metal such as Ti, Cr or Ta from an evaporating source 5 is blown on the cutting edges 31 in the form of metal ions to ion-clean the cutting edges 31. A gas such as N2 or C2H2 is then introduced into the vessel 1 from a pipe 6 and reacted with vapor of the metal such as Ti, Cr or Ta from the source 5 to deposit the hard nitride or carbide of the metal on the cutting edges 31 by ion plating. Since the carbide or nitride does not deposit on the parts excluding the cutting edge 31, many edges can be simultaneously treated in a high yield of starting materials.

The heavy fraction is removed from a zone near of the sidewall; the light fraction is removed from a zone nearer of the longitudinal axis of the chamber, than the heavy fraction outlet and if desired, an intermediate fraction may be removed from at least one separate intermediate zone between the light fraction outlet and the heavy fraction outlet. The apparatus comprises a separation chamber having a longitudinal axis, sidewalls and two ends; inlets through the first end for introducing suspension and auxiliary fluid; rotating means for deviating suspension and auxiliary fluid towards the sidewalls outlets for the heavy and the intermediate fractions in the second end of the separation zone; rotating means to collect the effluents from areas nearer the sidewalls to their respective outlets; and a light fraction outlet is provided in the first end of the separation chamber and is colinearly aligned with the longitudinal axis. Rotating means are provided to rotate the separation chamber around its longitudinal axis. Numerous alternative embodiments are described.

Abstract: PURPOSE:To simplify the formation of a mass damper and to effectively actuate it from small vibration by supporting a heavy weight having weight above buckling load being horizontally movable at the upper end of a column, and attaching a spring between the heavy weight and a floor to interpose a horizontal damper. CONSTITUTION:A heavy weight 3 is supported on a column 2 vertically provided on the housetop of a building 1, and a spring 5 is arrangedly provided between the heavy weight 3 and a buttress 4 vertically provided on a housetop floor to prevent a lateral slippage.
