Patent DE-19711326-A1 (DE)
Title: IGBT circuit with current limiting circuit
Inventor: OTSUKI MASAHITO
IPC: H01L29/78
Filed: 1997-03-18
Abstract: The current of a first conductivity IGBT sensor is controlled by the gate voltage, while the sensor is parallel-connected to the first IGBT. A second first conductivity IGBT has its current controlled by the gate voltage, and is parallel-connected to the first IGBT. A current-voltage converter acts on a rise or drop of a collector current of the sensor to provide voltage rise or drop. An active device current is controlled to conversion voltage for (dis)charging a gate capacitor, as monolithic chip of gate terminal. The first IGBT threshold voltage is higher than that of second one.
Patent DE-19718415-A1 (DE)
IPC: A23P1/00
Filed: 1997-04-30
Abstract: Apparatus for molding formable materials, comprises supply manifold(s) (44) for receiving formable material; plungers (52) for applying pressure to the material within the manifold; a mold plate (24) having at least one mold cavity (26) and driven between fill and discharge positions, the mold cavities being selectively exposed to the supply manifold when in the fill position; a clamp member (204) positioned adjacent the mold plate (24) in the fill position, and apply pressure on the clamp member to clamp the mold plate against the supply manifold compensating for deflection of the structural members to maintain the mold plate in firm clamping relation to the supply manifold. The arrangement eliminates the need for a thick or heavy clamp plate and a mold plate and clamp member of relatively thin section is utilized, to allow a machine having significantly increased width to be realized. The increased width of the machine increases capacity, and allows compatibility with other processing equipment. A mold plate knife assembly (35) cuts the formable material adjacent the mold cavities after filling to facilitate formation of precise portions of the formable material, and also functions to seal off the supply manifold prior to movement of the mold plate.

Patent DE-19751072-A1 (DE)
Inventor: JENTSCH KLAUS D
IPC: C07K14/71
Filed: 1997-11-18
Abstract: The invention relates to a blood withdrawal device having a receiving device on which a blood bag or a blood withdrawal vessel is placed during blood collection. A weighing device connected to the receiving device weighs the content of the blood bag and outputs corresponding data. A sensing device acquires the data output from the weighing device. In addition, a voice entry device is provided whose data can be input by voice. This voice data is converted into data having a processable data format by a converting unit and is likewise acquired by the sensing device. A corresponding possibility exists in which required data is input into the blood withdrawal device per voice entry thus leading to a higher flexibility with regard to an input of any large amount of data. In addition, the data can be reliably produced since it is no longer dependent on writing errors and the like made by an operator. The voice entry also allows for a simple manipulation of the blood withdrawal device.

Patent DE-19826687-A1 (DE)
Inventor: BOEHM JUERGEN
IPC: B60T7/08
Filed: 1998-06-16
Abstract: The invention relates to an electrically controlled braking system and its associated control method. Said system and method are characterised in that the service braking system can be activated by two service brake controls (4, 6) which can be actuated independently from each other by the driver. The main advantage of the present invention is that in case of a faulty service brake control (4), e.g. a brake pedal module, vehicle braking can be implemented with the aid of the service braking system through the second service brake control (6). Additional functions for the braking system, such as anti-blocking system and antiskid system, dynamic translation regulation, braking force amplifier, etc. can be implemented. The redundant design of the actuation system for said service braking system provides a high degree of operation safety, since full braking functionality can be maintained even in case of emergency braking.

Inventor: BRUCK PETER
IPC: G05D16/10
Filed: 1998-07-01
Abstract: The invention relates to a pressure control valve (1) comprising a control piston (3) which is able to slide in a valve hole (4). Under the effect of an energy accumulator (5) said piston in one direction of displacement connects a pump connection (23) with a consumer connection (24) and in the other direction of displacement connects the consumer connection (24) with a tank connection (21) such that the pump connection (23) is closed off. The aim of the invention is to provide a pressure control valve which functions reliably and in a stable manner even in case of elevated control dynamics.  To this end, independently of the direction of displacement of the control piston (3) a minimum volume flow present between the piston and the valve hole (4) dampens the displacement of the control piston (3).
