An automatic sampler for automatically sampling liquid samples to be introduced into apparatuses that analyze liquid samples, such as liquid chromatographs, includes a needle with a tapered tip end for suctioning and ejecting liquid, a mechanism for moving the needle in the horizontal and vertical directions, and an injection port having an insertion hole into which the tip end of the needle can be inserted. The outer diameter of the tip end of the needle is at least 0.1 mm and at most 0.6 mm. B...

A method and apparatus for operating an automatic transmission as a function of the engine rotational speed of a variable speed internal combustion engine. Upon a failure of the electronic control system, a return home of a motor vehicle under its own power is enabled. A delivery system delivers a working medium with which a transmission ratio adjusting device is actuated by a first control device that, in turn, is controlled by a pilot pressure that can be accurately changed by a second control...

A first embodiment of an automatic injector employs less material and fewer parts by eliminating an outer housing required in earlier automatic injectors. In a second embodiment, a manually operated sharps protector is provided. In a third embodiment, the sharps protector is deployed by a spring positioned internally of the sharps protector. In a fourth embodiment, the sharps protector is deployed by a spring positioned externally of the sharps protector. In all embodiments, removal of a safety ...

In an automatic transmission includes a main shaft and a counter shaft which are parallel to a crankshaft with the rotation of a torque converter on the crankshaft being transmitted to the main shaft through gears. A two-state speed change is conducted by gears provided on the main shaft and the counter shaft. An oil hydraulic clutch is operatively provided for connection and disconnection between the gear for reducing the spacing between the crankshaft and the transmission and to contrive a red...

An automatic transmission in a power unit with a torque converter and a hydraulic clutch to be engaged and disengaged for the switching of speed-change gears. Hydraulic pressure is applied to the clutch and is increased only when operating the clutch during acceleration of a vehicle. A pressure control valve is provided at a discharge port of an oil pump for supplying hydraulic oil to the hydraulic clutch. The pressure control valve includes a valve body, a valve element is axially slidably prov...

To measure a resistance value in a circuit by conventional method, one side of the resistor should be disconnected from the circuit, then an Ohmmeter is connected across the resistor. To measure a current through a component, one side of the component should be disconnected and an ammeter is connected between the 2 open terminals. As such mentioned above, measuring a resistance value or a milliamp current value is very inconvenient with a conventional multimeter. With the present invention, a vo...

System capable of being governed entirely by a computer, which permits the complete handling of a warehouse right from the entry of merchandise from suppliers up to its delivery to the customer, in the quantities and types of merchandise that may be specified. This requires the systems of storage and cargo breaking of the invention, which are interconnected in such a way as to permit the integrated handling of goods in the warehouse.

Multiple piezoelectric elements 35 are arranged in a row along the top of liquid level in a reaction vessel 11. An ultrasonic reflecting material 38 is installed on the bottom of the portion of the heat insulating bath 12 where heat insulating medium 13 is stored. A lateral ultrasonic wave 9b is generated on the lower side by actuation of the piezoelectric element 35. Wave 9b is reflected by the ultrasonic reflecting material 38. As lower ultrasonic wave 8 advances along the wall surface of the ...

The automatic transmission for motor vehicles, especially with transverse drive with six gear steps, has a main wheel train (2), a front-mounted wheel train (1) and five wet running clutches and brakes (A to E) and is connected to the output shaft of an internal combustion engine via a torsional-vibration damper; the front-mounted wheel train (1) located in force flow direction before the main wheel train (2) is spatially situated behind the main wheel train (2).

In an longitudinal type automatic transmission having an input shaft having driving gears, an output shaft having driven gears that are engaged with the driving gears to constitute transmission gear trains, and changeover mechanisms for selecting into a transmission gear train for transmitting a power, the automatic transmission is constructed to have the input shaft, the output shaft, and a driving shaft coupled to a final reduction gear, and has a bypass clutch that is arranged over the final ...
