    • A hydraulic control system comprising a hydraulic actuafor (20) having opposed openings (A, B) adapted to alternately functions as inlets and outlets for moving the element (21) of the actuator (20) in opposite directions and a variable displacement pump (22) with load sensing control for supplying fluid to said actuator. A pilot operated spool type meter-in valve (27) is provided to which the fluid from the pump (22) is supplied and a pilot controller (23) alternately supplies fluid at pilot pressure to the meter-in valve (27) for controlling the displacement of the meter-in valve spool (51) and the direction and velocity of the actuator (20). A pair of lines (32,33) extends from the meter-in valve (27) to the respective openings (A, B) of the actuator (20) and a pilot operated meter-out valve (34, 35) is associated with each line (32,33) of the actuator (20) for controlling the flow out of the actuator (20) when that line (32, 35) to the actuator (20) does not have pressure fluid from the pump (22) applied thereto. Pressure of fluid in the line (32, 33) to the actuator, which does not have pressure fluid from the pump, is applied to the meter-in valve (27) to apply a centering force which aids the pressure compensating flow forces to keep the flow constant.

    • Endotube intended particularly to be placed in the oesophagus and comprising at one end a funnel-like widening (1), a tube-like central part (2), and at the other end a bulging which widens towards the the central part (2), and which makes difficult to withdraw the endotube after its insertion through a narrowing. Said bulging is comprised of two thin walled hollow linings (3) which open to the inside of the central part (2) on which they make a projection and in the direction of which they raise and are terminated by a steep slope (4). It is thus possible, even in the case of the insertion of an endoscope intended to be placed into the endotube, to fold completely the linings (3) so as to easily guide them through a narrowing. The configuration of the funnel-like widening (1) enables to obtain, in association with an inserted placing tube, a torsion resistent connection.
    • 内管特别地意图放置在食管中并且在一端包括漏斗状加宽部(1),管状中心部分(2),并且在另一端包括朝向中心部分(2)变宽的凸出部, ,并且在其通过变窄插入之后使内管难以收回。 所述鼓起由两个薄壁空心衬里(3)组成,所述空心衬里在中心部分(2)的内部开口,在所述中心部分(2)上形成突起并在其方向上升高并且以陡坡(4)终止。 因此,即使在插入想要放入内管的内窥镜的情况下,也可以完全折叠衬垫(3),以便容易地引导它们通过变窄。 漏斗状加宽结构(1)能够与插入的放置管相关联地获得抗扭连接。

    • A semiconductor pressure transducer for detecting a pressure applied to a diaphragm. The pressure transducer comprises a diaphragm and a pressure detector including a Si single crystal which is so formed as to have a crystal face of {110} as the surface to which a compression force is applied, and which is attached to the pressure detector such that the crystal face is parallel to the diaphragm, a first pair of opposing electrodes provided on the Si single crystal in the direction having an angle of 45 degrees with the direction of on the crystal face of {110} and a second pair of opposing electrodes provided on the Si single crystal in the direction having an angle of 45 degrees with the direction of of the Si single crystal, either of the first or second pair of electrodes serving as output electrodes and the other pair serving as input electrodes and composite seat with one end thereof bonded to the crystal face of {110} of the Si single crystal so as to transmit the pressure applied to the diaphragm perpendicularly to the crystal face of the Si single crystal as a compression force. The pressure applied to the diaphragm acts perpendicularly to the crystal face of the Si single crystal as a compression force and the output electrodes output a voltage corresponding to the compression force.
