PURPOSE:To prevent the abrupt starting of car running, rapid increase in car speed, and the occurrence of instability in the number of engine revolutions by making gradual increase in the transmission torque of a car clutch in starting backward running less than that in starting forward running. CONSTITUTION:In starting forward car running, the transmission torque of a car clutch is gradually incr...

PURPOSE:To prevent the occurrence of a shock due to a shaky strike caused by a backlash or the like by controlling transmission torque of a car clutch so that its very small amount may be transmitted from an engine to a power transmitting mechanism during the coasting of a car. CONSTITUTION:A powder clutch 12 is perfectly disengaged in stopping a car, and an engine 10 therefore becomes into an unl...

PURPOSE:To prevent increase in a driving loss of a pump due to the excess pressure rise of line oil pressure by providing a correcting means for actuating signal to correct the actuating signal to a value smaller than its actual value when the actuating signal becomes larger than a predetermined definite value. CONSTITUTION:Hydraulic oil returning through a return passage to an oil tank 38 is draw...

PURPOSE:To prevent a belt slip by providing a flow control valve before a reducing valve to fix an oil flow rate, and thereby preventing an excessive oil from draining through the reducing valve. CONSTITUTION:An oil passage 31a is branched from a line pressure oil passage 22 to function as a circuit to generate a fixed base pressure, and communicates with a reducing valve 60 through a pressure com...

PURPOSE:To automatically lighting up a lamp by effectively utilizing the wind power by installing a fan in the front part of a buoy body formed into an aeroplane trunk form and installing a power generator inside and a lamp in the rear part and supporting a buoy body in rotatable ways onto a buoy. CONSTITUTION:A buoy body 4 is formed to an aeroplane trunk body form having a vertical rudder 2 at th...

PURPOSE:To enable the effect of engine brake to be exercised satisfactorily by expedit ing the change-over from a high-speed mode to a low-speed mode at the time of an engine brake control, while, an auxiliary transmission device and a continuously vari able transmission device are controlled automatically. CONSTITUTION:By combining a continuously variable transmission device 30 with an auxiliary ...

PURPOSE:To prevent a shock of speed-change from being generated in an automatic transmission of the type, in which a non-stage transmission is directly connected with a staged sub-transmission by controlling the flow of hydraulic oil at the time of a power-on down-shift and a power-off down-shift most suitably. CONSTITUTION:This automatic transmission for vehicles is designed in such a manner that...

The invention relates to a transferable paint film which has a silicone layer serving as a separating layer, said silicone layer being highly cross-linked and of the alkenyl-group-containing polyaddition type and including an adhesive layer as well as a paint layer. The paint layer can be peeled off along with the adhesive layer by hand, and stuck on a surface to be treated with paint.

The transmission ratio of a continuously variable transmission [100] is controlled by varying the effective diameters of driver and driven pulleys [H, K] mounted respectively on input and output shafts [G, J] with a V-belt [I] trained around the driver and driven pulleys [H, K]. The effective diameter of the driver pulley [H] is increased according to a signal [Pg] proportional to a vehicle speed ...

A system for a continuously variable transmission has a line pressure control valve (40) having a spool (42), a first hydraulic circuit having a pump (21) for supplying oil to the transmission through the line pressure control valve (40). A second hydraulic circuit is provided for supplying oil to the line pressure control valve (40) so as to shift the spool (42). A flow rate control valve (80) is...

Ein optischer Körper aus vernetzten Polymeren wird durch ablative photochemische Zersetzung bearbeitet. Hierzu wird das vernetzte Polymer einer gesteuerten, kohärenten Strahlung ausgesetzt, deren Photonenenergie wesentlich höher ist als die Dissoziationsenergie der kovalenten Bindungen im Polymer und deren Fluenz ausreicht, die resultierenden Zersetzungsprodukte abzutragen.; An optical element mad...

A system to ensure continuous thread feed from a series of spools carrying finite lengths of thread comprises a yoke or belt with spindles to carry at least two spools near guides to lead their threads on parallel paths opposite a device for entwining the leading end of one yarn with the trailing end of the other, when appropraite. The emptied spool is discarded for replacement or reloading. Activ...

The multilayered composite wound dressing comprises of a semipermeable membrane, a permeable supporting and reinforcing layer, and a non-stick, self-sealing biodegradable tissue interface. The semipermeable membrane may be a synthetic collagen, an alginate or a biocompatible polymer and it controls the rate of water vapour transmission from the wound surface. The permeable supporting and reinforci...

The solid-bowl centrifuge drum 1 is equipped with a weir 3 which is formed by two weir plates 5, 6 which are arranged at a distance from one another. The weir plate 5 which is directed towards the interior 2 of the drum has a larger internal diameter than the weir plate 6 which is directed towards the skimming chamber 4. Between the weir plates 5, 6 there is a discharge channel 7 which can be clos...

The invention is directed to a stand for an x-ray examination apparatus comprising a telescoping column that, for example, guides an x-radiator adjustably in the direction of its longitudinal axis and comprises at least three tubular telescope parts joined inside one another, whereby the telescope parts are coupled such to one another that, given adjustment of the x-radiator, the same relative dis...

An optical element made from crosslinked polymers is worked by ablative photochemical decomposition. To this end, the crosslinked polymer is exposed to controlled, coherent irradiation whose photon energy is significantly higher than the dissociation energy of the covalent bonds in the polymer and whose fluency is sufficient to remove the resultant decomposition products.

It was previously thought that brewers' yeast, Saccharomyces cerevisiae, was incapable of employing mannitol or sorbitol as a source of carbon during propagation in a catabolite derepressive mode. The invention is based on the discovery that many strains of S. cerevisiae can in fact employ mannitol and/or sorbitol in this way. Simple tests reveal those strains that are suitable. Positive action is...
