Abstract: A device having a number of general registers each allocated an input<sup>/</sup>output port and a number internal "buried" state registers. A user-controlled signal permits observation of the contents of the buried state registers at an input/output port although these registers are not allocated an input! output port. Each register is connected to a logic circuit internal to the device by a dedicated feedback path so that all registers can be used to specify states in a state machine sequencer. A fuse-programmable XOR gate permits a user to control generation of signals at the ports by permitting enabling and disabling of an inverting output buffer. Asynchronous reset and synchronous preset of the registers is prov ided. In addition to the dedicated feedback paths, programmable feedback paths are provided. An output inverter can selectably be enabled from internal signals or from an external pin. The input/output circuit can be deployed in banks, each bank selectably receiving the same or a different clock. The registers can be preloaded via an internally-generated signal or from the external pins. In an alternative embodiment, a programmable AND array and a pair of programmable OR arrays, each serving one of the banks, provides a flexible programmable logic array device with observable buried states.

Granted: 1992-03-18
Abstract: Des circuits hydrauliques de commande d'embrayage possédent normalement des soupapes de sûreté modulatrices contribuant à un embrayage sans à-coups. Il convient également de s'assurer que la pression du circuit est réduite à un niveau faible de sorte que le piston de charge est entièrement remis en place avant l'engagement initial de l'embrayage nouvellement rempli. Dans le présent agencement, dans le but de garantir que le piston de charge a complètement repris sa position initiale, il est prévu un mécanisme (120) qui établit un rapport entre la pression du fluide dirigé vers l'embrayage (12/14/16/18) et la pression du fluide agissant sur le piston de charge (100) de la soupape de sûreté modulatrice (50), de sorte que le fluide sous pression agissant sur le piston de charge pendant le remplissage de l'embrayage est déchargé vers le réservoir (22) en vue de permettre au piston de reprendre sa position initiale même si la pression du fluide arrivant à l'embrayage est encore à un niveau de pression supérieure. Le mécanisme à soupape de rapport (120) est situé à l'intérieur du boisseau de clapet (80) de la soupape de sûreté modulatrice (50), assurant ainsi un mécanisme à soupape simple et compact, qui réduit l'encombrement total du système et élimine d'autre part des conduits et/ou des canalisations supplémentaires.

Title: Toggle type die-fastening apparatus
IPC: B29C45/68
Filed: 1987-09-29
Granted: 1992-08-12
Abstract: Disclosed is a toggle type clamping apparatus having a construction wherein a fixed platen, to which one of half of a mold is fitted, supports and guides amovable platen having the other half of the mold fitted to a plurality of tie bars one of the end of which is fixed and the other end of which is supported by a toggle support, and the half mold of the movable platen is pushed to the half mold of the fixed platen by a toggle mechanism fitted between the toggle support and the movable platen. A clamping force adjustment nut for receiving the reaction of the clamping force by the toggle mechanism mates with the end of each tie bar on the toggle support side, and an adjustment cylinder connected to a hydraulic circuit is formed at this mating portion. Since the pressure inside each adjustment cylinder is controlled by a pressure regulation valve so as to match with the clamping force set by a setter, all the tie bars can receive an equal clamping force and imbalance of clamping force of tie bars resulting from a change in thermal equilibrium during the operation of the molding machine can be eliminated. <H0> ABSTRACT </H0> A toggle-type die-fastening apparatus has a movable platen that carries one mold part and is supported by and guided along a plurality of tie bars whose one ends are fixed to a fixed platen on which another mold part is mounted. The other ends of the tie bars are supported by a toggle support, and a toggle mechanism is disposed between the toggle support and the movable platen for pressing the mold part carried by the movable platen against the mold part mounted on the fixed platen. A die-fastening force adjusting nut is threaded onto the end portion of each tie bar that is closer to the toggle support so as to bear the reaction of the die-fastening force generated by the toggle mechanism. An adjusting cylinder is formed in this portion, and it is connected to a hydraulic circuit so that the pressure within each of the cylinders is controlled by a pressure adjusting valve in such a manner as to correspond to a die-fastening force set by a setting device. Therefore, the die-fastening forces of all the tie bars can be made the same, thereby eliminating any imbalance between the die-fastening forces of the tie bars caused by changes in thermal balance during the operation of the molding machine.
