IPC: G11C16/06

Abstract: A novel circuit for initiating a first read cycle when power is first applied to the memory device is disclosed. The circuit compares the ramping up of the word line voltage signal to a stable reference voltage using a comparator. Once the word line voltage reaches a predetermined level, but before it reaches its maximum value, the comparator trips. The transition of the comparator output is sensed by an address transition detection circuit which subsequently triggers a read cycle of the memory, thus creating a dummy read access without any requirement that the input address actually make a transition. A memory access time later, valid data is available at the output of the memory array. A voltage divider is used to divide the word line voltage to a suitable level for input to the comparator. The stable reference voltage serves as the source of the word line signal, besides being input to the comparator. A voltage multiplier is utilized to generate the word line signal from the voltage reference. Alternatively, the word line voltage may be supplied by an external source such as the supply voltage. Both the voltage multiplier and the voltage divider include programmable trimming transistors which allow tuning of their respective outputs. In addition, enable circuitry is included which disables the first read cycle circuitry in order to reduce power consumption after the first read cycle is initiated.

Title: Striking plate
Inventor: BRAND HORST
IPC: E05C17/16
Filed: 1997-06-09
Abstract: The plate has a bar which forms an opening (6) for a locking pin at one end, and which can pivot on the plate at its other end. The opening lies in a defined position relative to the edge of the plate when the bar is swung in, and this position can be adjusted. The adjustment may be achieved using a stop (13) against which the edge region of the opening acts under gravity, when the bar swings in. The edge of a shoulder which surrounds the opening may rest on a slope (11) or recess, in order to ensure this gravity action.

Abstract: A multilayer, liquid-tight nonwoven fabric (10) in the form of a composite material with at least two layers comprises spun-bonded fabric (12, 16) and melt-blown fabric (14), bonded/welded together by thermobonding at discrete points. The starting material for both components consists of polymer granules which are processed to give a liquid melt from which the fibres/filaments for the layers are made. The fibres (18) contain layer(s) of additives (20, 22) which reduce the wettability of the fibre surface by liquids with a surface tension so low that their contact angle without the additives would be from above 0 to below 90 degrees , thus preventing penetration of fabric (10) by liquid. Additives (20, 22) are distributed throughout the fibre cross-section, and also on the fibre surface (18) as a result of diffusion. Also claimed is a process for the production of spun-bonded or melt-blown layers for this fabric, comprising (a) production of additive granules containing "FX 18 01" (RTM: fluorocarbon compound), (b) mixing these with pure polymer granules and (c) processing the mixture to obtain the required melt liquids.

Abstract: A hydraulic power steering apparatus includes a pump
(1) for discharging pressurized operation fluid, a power
cylinder (4) for generating assisting force, a control valve
(3) connected to the pump (1) via a fluid path for receiving
the operation fluid from the pump (1) and adapted to supply
the operation fluid to the power cylinder (4) in accordance
with operation of a steering wheel, a rubber hose (6)
disposed in the fluid path. A check valve (2) is disposed
between the rubber hose (6) and the control valve (3). Since
reverse flow of the operation fluid due to input of kick-back
force is prevented, tires to be steered are prevented from
undesirably steered against the driver's intention. Further,
a pressure relieving mechanism (16a, 18, 8, 9a, 9b or 15f) is
provided to relieve part of the operation fluid when the
check valve (2) operates. Therefore, the oil pressure within
the power cylinder (4) and the control valve (3) is prevented
from increasing excessively, so that the oil pressure within
the pump (1) does not reach a preset relief pressure.

Abstract: The drive incorporates a motor (3) and a controller (2) with pluggable connectors (4,5) and a microprocessor (6) timing the operation of switches (S1-S4) in an H-bridge circuit (7). A time-constant circuit (8) is wired to a fixed resistor (RX) whose value is uniquely related to the type of motor. The time constant determined by capacitance (CK) and resistance (RK) is much greater than either of the switching times (T1,T2). This enables the microprocessor to identify the motor unambiguously from the voltage (UMX) measured at its connector (5).
