Patent EP-0232796-A2 (EP)
Inventor: MCDONOUGH KEVIN C
IPC: G11C17/12
Filed: 1981-11-10
Abstract: A single-chip microprocessor device of the MOS/LSI type contains an ALU, several interal busses, a number of address/data registers, and an instruction register with associated control decode or microcontrol generator circuitry. The device communicates with external memory and peripherals by a bidirectional multiplexed address/data bus and a number of control lines. The ALU, registers and busses along with the control ROM are constructed in an interrelated layout whereby minimum space is needed on the chip. Like bits in all registers and the ALU are aligned and in a regular pattern. The busses are metal lines overlying each of the strips of ALU/register bits. Controls are polysilicon lines perpendicular to the busses and aligned with columns of the control ROM. The control ROM is an array of rows and columns of potential MOS transistors, compressed by eliminating column lines which contain no transistors. The number of bits per column is a minimum to enhance compressability producing a wide configuration (long row lines) which allows the columns for control signals to align with the part of the ALU/register strip where the signal is to be used. 
     In addition to the main off-chip memory, a smaller on-chip memory (including both ROM and RAM) is provided which allows execution of instruction sequences to emulate complex instructions are indistinguishable from "native" instructions since all memory fetches and the like are generated exactly the same way, and long instruction sequences are interruptable. This on-chip memory does not effect the off-chip main memory map. Microprocessors are thus made more versatile and can be customized with little design effort. Also, off-chip access of another memory separate from the main memory allows emulator functions or special instructions.

Abstract: Responsive to a first and a second main data signal and a subdata signal, a multilevel modulator produces a composite modulated signal which comprises a quadrature amplitude modulated component modulated by the first and the second main data signals and represented by a radius on a phase plane and a phase modulated component modulated by the subdata signal are represented by a clockwise and a counterclockwise shift on the phase plane. A multilevel demodulator carries out an inverse operation to reproduce the composite modulated signal into first and second reproduced main data signal and a reproduced subdata signal.

Abstract: An improved computer controlled hydraulic system for a conventional toggle-type plastic injection molding machine of the type comprising an injection assembly and a mold clamping assembly. The hydraulic system comprises a first low volume pump and a second high volume pump connected between a reservoir of hydraulic fluid and a pressure and flow control manifold. The output of the pressure and flow control manifold is connected to an injection control manifold, in turn connected to and operating the instrumentalities of the injection assembly. The output of the pressure and flow control manifold is also connected to a clamping control mani­fold, in turn connected to and operating the cylinder of the clamping assembly. An isolation manifold is con­nected between the pressure and flow control manifold and the clamping control manifold. A third low volume pump is connected between the reservoir and the isolation manifold. The isolation manifold is also connected to the reservoir. When unactuated, the isolation manifold connects the output of the pressure and flow control manifold directly to the clamping control manifold and recirculates the third pump to reservoir, when the machine is to perform sequential cycles such as conven­tional injection molding or conventional coining. When actuated, the isolation manifold disconnects the clamping manifold from the pressure and flow control manifold and connects the third pump to the clamping control manifold, enabling the machine to perform a coining cycle with individual and simultaneous clamping and injection control, and precise and repeatable position and speed control of the coining step.

Abstract: A flat core (1) made of elastic material, for example plastic foam, is provided with continuous holes (2). Support beads (3) are placed loosely in these openings (2) and the latter are closed by elastic outer layers (4) which are bonded on on both sides. Thus a mattress is obtained in a simple manner which has a relatively large number of firm support bodies located in a central zone and soft elastic outer layers. On the outside, the mattress corresponds to a customary mattress and can correspondingly be used as any customary mattress. However, with the inserted support bodies, it causes an uneven, punctiform support of a person lying on the mattress with locally increased pressure, which brings about a desired massage effect and, additionally, due to a piston effect favours forced ventilation towards the top. <IMAGE>

Abstract: A solid polymer electrolyte is in the form of a gel comprising a complex of a solid polymer (e.g. poly(ethene oxide) and an alkali metal salt (e.g. LiCl0₄), the polymer being cross-linked to inhibit its transformation from an amorphous form to a crystalline form thereby to improve the alkali metal ion conductivity of the electrolyte at lower temperatures. The electrolyte may be made by irradiating (e.g. by gamma radiation or an electron beam) a solution, preferably aqueous, of the complex to cause the polymer to cross-link and form a gel. The electrolyte may be used as a component in a solid state electrochemical cell (e.g. for a rechargeable lithium battery), where the gel form of the electrolyte assists fabrication.
