Title: Ordered packing checking appts. for electric components esp. integrated circuits
Inventor: HAUEIS NORBERT
IPC: H05K13/08
Filed: 1996-03-14
Abstract: The device checks that the electric components (2) are correctly packed in an ordered arrangement at the end of a production line. The production line has a handler (1) which feeds the prepared, assembled and marked electric components (2) to a packing station (23). The packing station (23) has an image processing system (40).

Inventor: VIEHMANN HANS-HEINRICH ING GRA
IPC: H02M3/07
Filed: 1996-03-28
Abstract: A power supply circuit arrangement supplies a high electric voltage to an electronic load circuit. The value of the electric voltage is higher than the value of a supply voltage (Vdd) for the disclosed circuit arrangement. The disclosed circuit arrangement has a pumping circuit (2) electrically connected to the load circuit and which transmits the high voltage to the load circuit depending on an internal switching signal (3), with a predetermined pumping frequency, so that the electric pumping power of the pumping circuit (2) absorbed by the load circuit is substantially dependent both on the value of the supply voltage (Vdd) and on the value of the pumping frequency of the switching signal (3) of the pumping circuit (2). The circuit arrangement has a control circuit (4) associated to the pumping circuit (2) and supplied with a voltage which is derived at least from the supply voltage (Vdd) of the pumping circuit (2). Depending on a control signal (5) which depends on the value of the supply voltage (Vdd), the control circuit (4) transmits to the pumping circuit (2) a switching signal (3) which acts on the pumping frequency used to generate the high voltage transmitted to the pumping circuit (2), so that the value of the pumping frequency of the switching signal (3) is indirectly proportional to the value of the supply voltage (Vdd).

IPC: B29C70/52
Filed: 1996-06-18
Abstract: Vehicle frame components (20) are manufactured using pultrusion techniques in which fibrous material is supplied from one or more sources (11) to a bath (13) or similar structure for applying a resin material to the fibrous materials (12), after which the fibrous materials (12) are pulled through a die (14) having an opening therethrough which corresponds in shape to the desired cross sectional shape of the vehicle frame component to be manufactured to conform to the shape of the opening formed therethrough and then the formed pultrusion (15) is pulled through a curing oven (16) which heats the resin to a predetermined curing temperature, causing it to harden into a rigid condition. As a result, the pultrusion (15) as a whole acquires a desired rigidity. Movement of the fibrous materials (12) and of the pultrusion (15) is effected by means of a pulling device (17). Following passage through the pulling device (17), the pultrusion (15) is cut to desired lengths by a conventional cutting machine. Additionally, openings of desired sizes and shapes may be formed in the pultrusion (15) by a conventional perforation machine. Pultrusions (15) of different shapes and sizes may be used to form side rails (21, 22) which are permanently joined together by transversely extending cross members (23, 24) by adhesive to form the vehicle frame component (20).

Patent DE-19637013-A1 (DE)
Inventor: HARRIS COLIN
IPC: H03K19/094
Filed: 1996-09-12
Abstract: A tri-state output driver comprising a pair of complementary field effect transistors (CMOS FETs) 1, 3 having sources and drains connected in a series circuit between a voltage rail VDD and ground GND has a third FET 2 in series between the pull-up FET 1 and output terminal OUT. In a high impedance state FET 2 protects the pull-up FET from high voltages at the output terminal which would otherwise cause it to conduct. The voltage at node N1 is maintained at less than a lower of an FET threshold of conduction voltage or diode turn-on voltage greater than the voltage of the voltage rail by connecting the gate of FET 2 through FET 5 to the output terminal when in a high impedance state. Node N1 is pulled to a low logic level by FET 6 so that it does not float. The circuit can be used with either 3.3V or 5V logic and voltage supply and can drive logic high or low levels into 3.3V or 5V CMOS inputs.

Title: Variable gain semiconductor amplifier circuit
Inventor: OKADA TORU
IPC: H03G1/00
Filed: 1997-03-17
Abstract: The control signals for both circuit types (1-1 to 1-n; 2-1, 2-2 to 2m) are generated in a control signal generating unit (3), using an attenuation value control signal in response the control.  This is such as to show a large amplification so that the first circuit type effects an amplification reduction, while the second circuit type generates a constant amplification.  When the attenuation control signal drops within the other variation range with a low amplification, the two control signals are generated so that the first circuit is saturated without amplifying any change, while the second circuit amplification is reduced accordingly.
