IPC: D03D47/30
Filed: 1990-12-27
Abstract: The present invention relates to a control method and control apparatus for controlling jet pressure of a picking nozzle in a jet room. The control method detects a flying characteristic of a filling yarn and inhibits descending control of a pressure controller for controlling the jet pressure when the unevenness exceeds a set allowable value, to prevent occurrence of picking defects such as short picking, looseness, etc. due to excessively low jet pressure. 
     In the control apparatus according to the present invention, a pressure controller can be positively controlled as in the above method by an auxiliary controller provided with flying characteristic detection means, unevenness calculation means and comparison means.

Abstract: For screwing in elements with an internal or external thread which have no attachment surface for the application of a defined torque, such as cable ducts for shielded cables, a tool consisting of two part-tools, one part-tool of which has a counter-thread matching the thread of the element to be screwed in, is proposed. The two part-tools engage coaxially inside one another and are connected to one another via a ramp-shaped form closure which has a greater pitch than the thread of the element. In a tool for screwing in the element, the direction of the pitch is the same as that of the thread of the element, whereas in a tool for loosening an element, the direction of the ramp is opposite. As a result of the greater pitch of the thread, a slight detachment of the tool from the element occurs upon slackening. <IMAGE>

Abstract: A top end retainer (78) for an air spring sleeve (54) in an automotive strut suspension system includes a elliptical clamping flange (80) having a perimeter equal to the circumference of the top end of the air spring sleeve (54) so that the sleeve (54) fits over the clamping flange (80) without stretching. A bushing aperture (84) in a centre web (82) attached to the clamping flange (80) is offset to an end of the flange (80). A piston rod (34) of the strut (10) is received in the bushing aperture (84) through an elastomeric bushing (94) and the centre web (82) is connected to the sprung mass (12) for rotation so that the strut (10) and the air spring (46) are rotatable about a steering axis. The geometric centre of the elliptical flange (80) is further offset from the longitudinal axis (28) of the strut (10) than would be the case with a circular flange having a diameter equal to the diameter of the top end of the air spring sleeve (54) so that the top end retainer (78) according to this invention contributes to optimization of the inclination of the line (102) along which the air spring resultant force (F2) is directed.

Abstract: An injector (10) has a single tapered valve (22) controlling fuel flow to a plurality of outlet passages (20). The entrance to each outlet passage has an orifice (42a,42b,42c,42d,42e,42f) surrounded by a raised valve seat (28a,28b,28c,28d,28e,28f). Each valve seat (28a,28b,28c,28d,28e,28f) is separated from the other valve seats by a recessed space (38). The valve (22) pivots about one end thereof as it is displaced from the valve seats to allow fuel flow through the outlet passages, and is constrained against other motion within the injector. The valve seats (28a,28b,28c,28d,28e,28f) are clustered beneath the opposite, free end of the valve (22). The orifices are sized to compensate for the unequal lift of the tapered valve (22) from the valve seats (28a,28b,28c,28d,28e,28f).

Abstract: A drive apparatus is disclosed which is designed to switch/excite a plurality of excitation windings of a stepping motor in a predetermined order. The drive apparatus (2) includes means (30, 60) for adjusting currents flowing in a plurality of excitation windings (24 A  to 24 E ) so as to reduce the periodic velocity fluctuation of the stepping motor (1). In addition, the drive apparatus (2) includes a memory unit (50) for storing the intrinsic velocity fluctuation data of the stepping motor (1) which is obtained while the exciting currents are adjusted. While the stepping motor (1) is driven, the velocity fluctuation data stored in the memory unit (50) is read out by an arithmetic unit (60). The arithmetic unit (60) outputs a pulse train (P) having a pulse rate which fluctuation to have a phase opposite to that of velocity fluctuation obtained from the velocity fluctuation data. This pulse train (P) is used as switching timing signals for switching/exciting the plurality of excitation windings (24 A  to 24 E ) in the predetermined order.
