Patent DE-19631113-A1 (DE)
Title: Single phase locked loop circuit for radio communications system
Inventor: HA JI-WON
IPC: H03L7/10
Filed: 1996-08-01
Abstract: The circuit synchronises a single oscillation frequency with a modulation frequency in a transmission mode, and with a demodulation frequency in a reception mode. The circuit contains a voltage controlled oscillator (VCO) (40), and a variable frequency divider (60) for the VCO output. There is also a phase comparator (20) to compare an output of the frequency divider with a reference oscillation frequency, a low pass filter (30) for the phase difference signal, a power supply, an adder and a controller (50). The power supply provides a first reference voltage in the transmission mode, and a second reference voltage in the receive mode. The adder combines a filter output voltage with the reference voltage, and the controller determines the frequency division ratio according to the mode selected. The VCO generates a modulation or demodulation frequency corresponding to an adder output.

Title: Synchronous semiconductor DRAM apparatus using e.g. 200 MHz clock signal
Inventor: TAKAI YASUHIRO
IPC: G11C7/10
Filed: 1996-08-26
Abstract: The apparatus includes a column address buffer memory (1), two column decoders (2,2') connected to the buffer memory, two read amplifiers (3,3'), and a data amplifier. Two first stages (4,4') of the data amplifier are respectively connected to two read busses (RIO1,RIO2). A data intermediate circuit (7) is connected to the second stage of the data amplifier (6). Provided with the address buffer is a burst counter and two address signals (YADD1,YADD2) are produced synchronously with every second clock signals.  The two decoders receive respective buffer signals synchronously with each second clock signal. Data signals compatible with respective column switch signals (YSW1,YSW2) of the respective column decoders are received by the read amplifiers and applied to the read busses. The read amplifier stages amplify voltages on the read busses and transfer them to a read/write bus (RWBS1) at every second clock signal, the stages being multiplexed so that signals from each first stage are alternately applied to the amplifier second stage (6) via the read/write bus. The intermediate circuit outputs data from the amplifier second stage with every single clock pulse.

Title: Method of controlling fuel-air mixture composition for IC engine with 3-way catalyst
Inventor: HUETHWOHL GEORG DR ING
IPC: F02D35/00
Filed: 1996-11-07
Abstract: The method involves detecting the engine (8) revs rate and operating temp. and the oxygen partial pressure in the exhaust gas flow. An additional air quantity to be added to the carburettor mixture is determined according to the detected data, the maximum being related to the detected engine speed. An air valve (7) with an opening limit is controlled to deliver the air quantity to the fuel-air mixture. The valve is opened for a given throughput in the absence of an oxygen partial pressure measurement signal on engine start-up. The valve is closed irrespective of further control when the engine speed falls below a defined minimum value and changes in the negative direction by more than a defined amount.

Title: Brake control/monitoring method for heavy motor vehicle
Inventor: BIEBER GEROLD
IPC: F16H61/02
Filed: 1996-11-20
Abstract: A heavy vehicle, such as a freight vehicle or lorry with automatic transmission control, has a brake system monitoring control which computes the total weight of the vehicle from the brake reaction and from the traction control. This computed value is compared with a threshold value, and if it exceeds that value a warning is given to the driver and the transmission is set to a low ratio i.e. the vehicle is operated in a more stable condition.  The weight of the vehicle is used to modify the braking/traction control, and the vehicle weight is periodically computed and a mean value derived. The computation is performed at zero gradient and with low acceleration.

Title: Sun protection parasol with ventilation
Inventor: RASCH BODO DR
IPC: F24F5/00
Filed: 1997-02-14
Abstract: The parasol has a vertical mast, with radially projecting parasol arms carrying solar radiation screens, and a ventilator unit. The arms (13) form part of the ventilator unit and are able to rotate about the longitudinal axis of the mast (12). The energy required to rotate the arms is generated by photo-voltaic elements, which are positioned on the upper surface of the flat solar radiation screens. The arms can be folded down to lie along the mast, and with increasing rotational speed, the arms are folded upwards. When a set speed has been exceeded, the arms lock into a rigid, fully extended position, and remain in this position even if the speed drops.
Patent DE-19706105-A1 (DE)
Inventor: WOLF THOMAS DR ING
IPC: G05B19/19
Filed: 1997-02-17
Abstract: According to the invention, the control method is used to produce a manipulated variable (y) to control a hydraulic mechanism (HA). To this end, at least one desired value (vs) for the speed of the hydraulic mechanism (HA), a first parameter (K1) which emulates the transmission procedure (KV, AO) of the hydraulic mechanism (HA), and a second parameter (K2) which emulates the internal resistance (KD, AK, AO), set against the hydraulic mechanism (HM) by the technical process (TP), are taken into account. One advantage is that non-linear sensitivities of the hydraulic mechanism can be taken into account to produce the manipulated variable (y) which controls the hydraulic mechanism (HA), thereby providing the added advantage of avoiding technically complex sensor technology. In one embodiment, the inventive control method is particularly useful for non-linear control of a plastic injection moulding machine.
