Inventor: UCHINAMI AMANOBU
IPC: B60R16/023
Filed: 1993-07-29
Abstract: The control device monitors the load current of the supplied electrical load, coupled to the dynamo and compares the load current gradient with a threshold level, to reduce the current fed to the dynamo energising winding to a given level for a defined time interval. Pref. the load current detector is activated to monitor the current gradient when the engine is in the idling condition, with the engine air intake rate increased when the detected gradient is above the threshold level, the defined time interval corresponding to the delay time for the engine revs to increase in response to the increased air intake level. ADVANTAGE - Maintains stable idling revs. when electrical load is switched in.

Patent DE-4405729-A1 (DE)
Inventor: LONMORE DAVID BEST
IPC: H05B37/02
Filed: 1994-02-23
Abstract: A lighting strip is disclosed which has a pair of power supply lines (12, 14) extending along the strip, and at least one lighting device (16) connected between the power supply lines (12, 14), and includes a power control device (18, 22) for controlling the electrical power supplied to the at least one lighting device.

Title: Device for increasing the bandwidth of an oscilloscope
Inventor: MOTTAGHIAN-MILANI DARIUS-KARIM
IPC: G01R13/32
Filed: 1994-02-24
Abstract: Device for raising the bandwidth of an oscilloscope into the UHF range. In this case use is made of the fact that, when representing the amplitude profile of a high frequency, it need not itself be amplified. It is in any case not resolved by the time base. The HF signal is represented by a substitute frequency which generates a chopper. It is thus possible, for example, to observe the modulation of a HF signal, inclusive of all DC and low-frequency components. In the exemplary embodiment, a device is described which makes it possible to represent a video line with all chrominance components on a 180 kHz audio oscilloscope. The outlay on circuitry is very low and inexpensive.

Abstract: A lock locates a connecting bar for a door or window. With the action of a single operation of the latch from the first to the second position, the latch is returned to the first position via the action of a spring. The connecting slide (13) to the connecting bar stays meanwhile in its locked position, and is only returned to the neutral position by once more operating the latch into the second position. A key actuated bolt (4) is only pre-closed in the locking position and is blocked in all other positions of the slide to the connecting bar. <IMAGE>

Title: Controlling switch-off of voltage-controlled IGBT power semiconductor switch
Inventor: BRUCKMANN MANFRED DIPL ING
IPC: H02M7/48
Filed: 1994-08-12
Abstract: A voltage-controlled IGBT power semiconductor switch (T2) has a reverse diode (D2).

Patent DE-4433314-A1 (DE)
Title: Control method and device for substances escaping from tanks in internal combustion engines
Inventor: NEMOTO MAMORU
IPC: F02D41/00
Filed: 1994-09-19
Abstract: According to one embodiment of the invention the quantity of substance escaping is controlled according to the intake air quantity of an internal combustion engine. During normal operation of the engine an air-fuel ratio for the substance escaping is calculated according to a rate of escape and a value for the air-fuel feedback control. During non-steady engine operation a set point for the feedback control of the air-fuel ratio is calculated according to the rate of escape and the air-fuel ratio of the substance escaping. If the difference between the value of the feedback control for the air-fuel ratio and the set point for the feedback control for the air-fuel ratio exceeds a predetermined value, the value for the feedback control of the air-fuel ratio is corrected. An undesirable fluctuation of the air-fuel ratio of a fuel mixture fed to the cylinders, which occurs in the event of rapid fluctuations of the rate of escape, can be suppressed.

Title: Mains-operated phase-angle controller e.g for lighting or motors
Inventor: KULLIK GUENTER R J
IPC: H05B39/04
Filed: 1994-10-05
Abstract: A mains-operated control unit for electrical loads is developed as a phase-angle or phase-chopping controller, a phase controller or a pulse-group chopper and has an electronic or electro-mechanical switch for the load, which is triggered (off or on) by one or more integrated control circuits or a microcomputer either in each half wave or in an established mark-space ratio relative to the zero crossing point of voltage or current.  The change of switching instant is dependent on whether a pulse sequence generated as a subsidiary function of the control circuit(s) is received or not at the input of the control circuit. The pulse sequence is applied through an input resistance and can be short-circuited by a button.

The connector can be variably spaced from the hub and the disc bearing is of the friction-free or sliding type. The shaft and baby seat etc. move up and down at the periphery so the shaft rotates to give the desired rocking motion.
