PURPOSE:To aim at ensuring rapid and precise responsiveness, by controlling the opening degree of a throttle valve so that a pressure or an amount of intake air which is calculated in accordance with a desired torque obtained from a desired horse power is made to coincide with an actually measured value in order to carry out drive control with the use of a CVT. CONSTITUTION:In order to carry out d...

PURPOSE:To aim at ensuring rapid and precise responsiveness, by compensating the gain of feed-back in accordance with the opening degree of a throttle valve and the rotational speed of an engine in order that the feed-back control of the throttle valve is carried out by computing a desired intake-air pipe pressure in accordance with a desire torque. CONSTITUTION:A control circuit 60 carries out th...

PURPOSE:To aim at ensuring precise responsiveness, by adding a feed-forward term during abnormal operation in which the difference between a desired intake-air pipe pressure and an actually measured intake-air pipe pressure is greater than a predetermined value and to forth, in order that feed-back control is made to the opening degree of a throttle valve in accordance with the desired intake-air ...

PURPOSE:To enhance the load followability of a governor free control device, by setting an affection with which a plant is influenced by output variations due to governor free operation during the system frequency varies, within an allowable range, by suitably controlling the range of the output variation and the variation rate of the output during the governor free operation. CONSTITUTION:Either ...

In a yarn splicing process comprising steps of allowing a yarn from a bobbin and a yarn leading to a package to intersect with each other in a yarn splicing device; cutting off yarn end portions extending from the yarn splicing device; splicing the cut yarn ends; and re-starting the winding operation for winding up a yarn on a package from a bobbin, the process further includes steps of clamping t...

Ethylene glycol is prepared by a process in which ethylene oxide is extracted from an aqueous solution with near-critical or super-critical carbon dioxide. Thereafter an ethylene oxide-carbon dioxide-water mixture is contacted with a catalyst to form ethylene carbonate, which is then hydrolyzed to ethylene glycol in the presence of the same catalyst. The ethylene glycol is separated as product and...

Cross-cutter for cutting web material, in particular corrugated cardboard, comprising a pair of knife shafts which are tubularly supported for rotation on a core secured in the machine frame and commonly driven by a drive means, the knives temporarily contacting each other during the cutting operation under bias, if necessary, at least one end of at least one core having associated therewith a pow...

To mount the bobbins on the bobbin plates of two-for-one twisting machines, the bobbin plates conventionally have mandrels, onto which the bobbins are slipped. This necessitates a particular constructional height of the two-for-one twisting spindle, since the bobbins have to execute an axial movement in order to be slipped on. To avoid this, the tubes are provided with tabs (56) on a circumferenti...

In a centrifuge, the kinetic energy contained in the separated fluid is recovered to a great extent by removing the fluid from the circulating layer of fluid by means of one or more skimming tubes (19) and is conducted directly or after intermediate storage in a high-level tank (23) to drive elements of a fluid flow engine (27). The drive elements can be used to drive, for example, the centrifuge ...

The invention relates to an X-ray diagnostic apparatus with a support arm (12) supporting at its one end (11) a monitor (10), and with a patient-supporting bench (5), the monitor (10) being displaceable relative to the patient-supporting bench (5) by means of the support arm (12). The monitor (10) can be moved along the patient-supporting bench (5) and can be driven into a park position situated a...

A method of preventing the yellowing of the outermost coating of a multicoat coating system is disclosed. The method comprises initially depositing onto a conductive substrate by cathodic electrodeposition a primer coating comprising at least one layer of an amine-epoxy resin adduct and a cross-linking agent, and then curing said primer to a hard, durable film. Then, depositing a second coating on...

PURPOSE:To detect the fine unevenness of the entire surface of a body to be inspected easily for the inspection of the surface, by inspecting the illuminance distribution of a spatial image of reflected light from the body to be inspected by shifting the focal point of a convex lens which focuses and image-forms said reflected light. CONSTITUTION:Light from a light source 11 is collimated by a len...

1. High-molecular polyester, consisting substantially of chain members of the Formula -(-O-X-O-Y-)- , which in these chain members as member X substantially has the structures see diagramm : EP0064972,P9,F1 or see diagramm : EP0064972,P9,F2 and as member Y substantially has the structure see diagramm : EP0064972,P9,F3 characterized in that the polyester has an inherent viscosity of greater th...

The invention relates to a process for the lamination of metal sheeting having a double layer comprising hydrated chromium oxide as the upper layer and chromium as the lower layer, with a biaxially oriented polyester film which has been coated with an epoxy resin containing a curing agent. The laminate has excellent corrosion resistance and adhesion of the polyester film to the base material, even...

A ski binding includes a base plate adapted to be secured to a ski, a cover plate supported on the base plate for pivotal movement about a vertical axis, and an adjustable release arrangement for yieldably resisting pivotal movement of the cover plate in either direction away from an initial position. The release arrangement can be adjusted from a side of the binding. Front and rear holding mechan...

A heat resistant vessel having an improved colorant contamination resistance is made of a thermoplastic polyester resin having a crystallinity of 20% or more by forming an inorganic coating layer comprising a silicon compound or a metal oxide-containing silicon compound of at least one of an oxide and hydroxide of mainly silicon on a surface of the polyester resin. Formation of the inorganic coati...
