Patent DE-3817895-A1 (DE)
Title: Insert-shaped body
Inventor: SATO YOSHITAKE
IPC: H01H1/58
Filed: 1988-05-26
Abstract: The invention relates to an insert-shaped body, comprising a metal part (17), a part of resin material, into which the metal part is moulded, and a sealing material (20), in order to provide a reliable seal between the metal part and the resin material. The sealing material is permeable and flexible and has affinity. The sealing material may be applied beforehand to a surface of the metal part, which is for example present in the form of a connection. The sealing material covers over any slight irregularities in the surface of the metal part or fills them. The applied sealing material shrinks with the shrinking of the resin material during the moulding operation along a surface of contact between the metal part and the part of resin material, which is a connection frame if the metal part is a connection. The sealing material may be a liquid rubber seal of a semi-dry viscoelastic type, which is predominantly composed of a special synthetic rubber. <IMAGE>

Patent DE-3818946-A1 (DE)
Title: Method for operating a drum screening machine
Inventor: BACH VOLKER
IPC: B01D33/073
Filed: 1988-06-03
Abstract: Drum screening machines impinged from the outside have a scraper strip which is positioned at an angle against the direction of rotation and which is pressed on by spring suspension. During operation with heavy material to be screened, blockages occur on the scraper edge which can extend into the screening gap and can lead to lifting of the scraper strip. According to the innovation, a method remedies this which is characterised in that the screening drum is driven in reverse direction of rotation at certain intervals. The duration of the reverse run is only brief and extends to less than one complete revolution, preferably half a revolution.

Title: Non-volatile semiconductor memory with NAND cell structure
Inventor: MOMODOMI MASAKI
IPC: G11C16/30
Filed: 1988-09-16
Abstract: The invention concerns an erasable, programmable read-only memory with NAND cell structure, which includes NAND cell blocks (B11, B12, ...), each of which has a selection transistor (Qs) which is connected to the relevant bit line (BL1), and a series arrangement of memory cell transistors (M1, M2, M3, M4). Each cell transistor has a floating gate and a control gate. Word lines (W11, W12, ...) are connected to the control gates of the cell transistors (M1, M2, M3, M4). In data writing mode, a selection transistor (Qs) of a particular cell block (B1) which contains a selected cell is set conducting, so that this cell block (B1) is connected to the relevant bit line (BL1). In these conditions, a decoder circuit (14, 16) stores a desired data unit in the selected cell, by applying a high-level voltage ("H") to the bit line (BL1), and a low-level voltage ("L") to the word line which is connected to the selected cell, applying a high-level voltage to one or more memory cells between the selected cell and the bit line (BL1), and applying the low-level voltage to one or more memory cells between the selected cell and earth. <IMAGE>

Title: Tachometer having a dual display for a motor vehicle
Inventor: KIMURA SHYOUJI
IPC: G01P1/08
Filed: 1988-10-07
Abstract: In a tachometer having a dual display for a motor vehicle, the dial (20) is provided with scale markings (20S), which are switched on when an ignition key is turned on, with numerical values (20L) for low speed, which are used for a low speed range and are illuminated when the vehicle speed varies, for example, from 40 to 140 km/h, and with numerical values (20H) for high speed, which are used for a high speed range and are illuminated when the vehicle speed varies, for example, from 140 to 280 km/h. The current vehicle speed is compared with a reference speed (for example, 140 km/h) in the form of a voltage, and the numerical values are subsequently selectively illuminated in order to display the low or high speed. Furthermore, the pointer (14) is preferably rotated at a rate of 10 km/h per scale marking interval in the low speed range but at a rate of 20 km/h per scale marking interval in the high speed range. <IMAGE>

Patent DE-3844418-A1 (DE)
Title: Adhesive web for sowing, and method of sowing and pregerminating
IPC: A01C1/04
Filed: 1988-12-30
Abstract: The invention provides means and method for improving the sowing process of an expected number of seeds which are spaced as required, and for rapid sowing.

Patent DE-3902071-A1 (DE)
Inventor: BAUMGARTEN PETER
IPC: B60S1/34
Filed: 1989-01-25
Abstract: In a windscreen wiper system, the windscreen wiper (11) moves back and forth along a guide channel (25). The windscreen wiper is fastened to a driver (30) driven by a flexible element (27) which transmits the movement in such a way that its line of action extends laterally with respect to the median line of the guiding region of the driver, which is perpendicular to the direction of displacement. The windscreen wiper can thus reach and clean the outer edge of a headlight glass even within the confined space in which a motor vehicle headlight is mounted.

Patent DE-3937158-A1 (DE)
Inventor: ODENDAHL ALFRED DR ING DR
IPC: H02J7/00
Filed: 1989-11-08
Abstract: Proposed is a control unit for a battery-powered device, the unit detecting, using an existing connection as a test connection, an overload condition in the battery and/or electrical device. This is done by using the charging control connection of a temperature-dependent resistance which is in thermal contact with the rechargeable battery. This connection, which is usually used to control a charging unit, is utilized during battery-powered operation of the device as the test output for monitoring the battery temperature. Since the temperature gradient is also determined, this signal can also be used to monitor the electrical device, for instance an electric motor, for an overload condition.
