3313 results about "Changeover" patented technology

In manufacturing, changeover is the process of converting a line or machine from running one product to another. Changeover times can last from a few minutes to as much as several weeks in the case of automobile manufacturers retooling for new models. The terms set-up and changeover are sometimes used interchangeably however this usage is incorrect. Set-up is only one component of changeover. Example: A soft drink bottler may run 16oz glass bottles one day, perform a changeover on the line and then run 20oz plastic bottles the next day.

Starter for an internal combustion engine

PCT No. PCT/DE97/01663 Sec. 371 Date Sep. 22, 1998 Sec. 102(e) Date Sep. 22, 1998 PCT Filed Aug. 7, 1997 PCT Pub. No. WO98/20252 PCT Pub. Date May 14, 1998The starter apparatus for an internal combustion engine (2) includes a starter-generator including a device for rotating a flywheel (5) to a predetermined rotational speed and a device for rotating the crankshaft (3) of the engine to directly start the engine; at least one clutch (6, 7) for directly coupling or disengaging the flywheel (5) with the crankshaft (3) of the engine (2) so that the flywheel (5) starts the engine (2) with the rotational energy stored in the flywheel (5) by the starter-generator in an impulse starting method and a changeover device (11) for changing between the impulse starting method based on engagement of the flywheel (5) with the engine (2) and a direct starting method in which the starter-generator (4) is directly coupled to the engine, wherein the changeover device switches between the direct starting method and the impulse starting method as a function of a temperature of the engine (2) so that the impulse starting method is used at comparatively lower temperatures and the direct-starting method is used at comparatively higher temperatures. The starter apparatus also includes a device for adaptively determining the threshold for changeover between impulse starting and direct starting.

Differential circuit, amplifier circuit, driver circuit and display device using those circuits

A differential circuit and an amplifier circuit for reducing an amplitude difference deviation, performing a full-range drive, and consuming less power are disclosed. The circuit includes a first pair of p-type transistors and a second pair of n-type transistors. A first current source and a first switch are connected in parallel between the sources of the first pair of transistors, which are tied together, and a power supply VDD. A second current source and a second switch are connected in parallel between the sources of the second pair of transistors, which are tied together, and a power supply VSS. The circuit further includes connection changeover means that performs the changeover of first and second pairs between a differential pair that receives differential input voltages and a current mirror pair that is the load of the differential pair. When one of the two pairs is the differential pair, the other is the current mirror pair. In a differential amplifier circuit, there is provided an added transistor connected in parallel to a transistor, which is one transistor of a differential pair transistors, whose control terminal is a non-inverting input terminal. The added transistor has a control terminal for receiving a control voltage which is set so that, when an input voltage applied to the non-inverting input terminal is in a range in which the transistor whose control terminal is the non-inverting input terminal is turned off, the added transistor is turned on.

Device and method for testing linear reciprocating sliding friction and abrasion

The invention discloses a device and a method for testing linear reciprocating sliding friction and abrasion; the device consists of a transducer, a workbench, a sample table, a dragging frame, a force sensor, a changeover switch, a counter, a locking device, a guideway, a baffle, a cable wire, a reducer, a peak value stabilizer, a control part and an auxiliary component; the equipment can automatically complete the abrasion test of an arranged period and can manually complete the test to friction coefficient. The testing method comprises the following steps of: leading the friction block and the sample to reciprocate to slide horizontally with constant pressure, obtaining an abrasion weight loss rate after abrading, keeping a certain positive pressure and leading the sliding block to move from stillness to uniform movement, thus obtaining the maximum static friction coefficient and the sliding friction coefficient. The device and the method can realize uniformly linear and reciprocating relative sliding abrasion in long unidirectional journey, test the maximum static friction coefficient between two bodies and the maximum static friction coefficient, the speed, the load and the adjustable journey with other materials, and can be widely applied to the detection of various samples of different materials and different structural forms.
