Patent EP-0471932-A2 (EP)
Inventor: CHAPPELL BARBARA ALANE
IPC: G06F12/0855
Filed: 1991-06-07
Abstract: A virtual multi-port RAM (VMPRAM) structure has automatic port sequencing and single-port array density and speed. VMPRAM employs input-triggered, self-resetting macros in a pipelined architecture to provide multiple self-timed on-chip cycles during one machine cycle. The VMPRAM incorporates an SRAM segmented into many input triggered, self-resetting, fast cycling blocks. A timing signal is derived from a selected SRAM block for releasing the next select signals and data to the SRAM blocks. The SRAM block inputs are only the data input bus and the decoded signals needed to select a wordline and a bitline pair, and the SRAM block cycle is only the time needed to provide adequate pulse width for word lines and bitlines. Each SRAM block, and all the circuit blocks in the path to access the SRAM blocks, are input-triggered and self-resetting. The multiple address (35, 37, 39) and data input latches (55, 57, 59) are multiplexed at the driver to the true and complement buses to the SRAM segments, and those buses are self-resetting. Similarly, the selected SRAM block reads data out onto a self-resetting bus (63), and address (24, 26, 28) and data inputs (44, 46, 48) are latched in blocks that are set up for the release signal by the release of the adjacent block, and these blocks are all self-resetting.

Abstract: For controlling a solenoid actuator in PID control mode in response to input control information, the temperature of the coil of the solenoid actuator is detected or estimated, and the constant or constants necessary for PID control calculation are determined taking into account the resulting temperature. The input control information is subjected to the processing operation for PID control operation by the use of the determined constant or constants, whereby desired PID control characteristics can be obtained irrespective of changes in the temperature of the coil of the solenoid actuator. As a result, in particular, the step response and other dynamic characteristics can be improved.

Abstract: Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum elektroerosiven Abrichten von Schleifscheiben mit elektrisch leitender Bindung. Das Abrichtwerkzeug besteht aus einer in sich zweigeteilten, zylindrischen Elektrode, deren Elektroden (2, 3) eine unterschiedliche Polarität aufweisen und durch eine Isolierung (4) voneinander getrennt sind. Ein Spannungskreis wird über beide Elektroden (2, 3) geführt. Die Spannung kann entweder eine Gleichspannung oder eine Wechselspannung sein. Das Abrichtwerkzeug rotiert und wird mit konstanter Kraft an die Schleifscheibe (1) angedrückt. Die beiden Abrichtelektroden (2, 3) werden über Bürsten (5, 6) aus einem Generator (7) so mit Strom versorgt, daß er durch die Elektrode (3) in die Schleifscheibe (1) und von dieser in die andere Elektrode (2) zurückfließt. Die kommutadorähnliche Anordnung der beiden Elektroden (2, 3) und der Bürsten (5, 6) ruft bei einer Drehung einen periodischen Wechsel der Polarität der angelegten Spannung hervor, der auf einfache und effektive Weise ein gleichmäßigeres Abrichten ermöglicht. <IMAGE>

Abstract: An IC card of the present invention is capable of preventing an internal battery from being rapidly consumed and internal data from being volatilized due to frequent use or erroneous starts caused by external noise. The number of starts of the card and the number of erroneous starts thereof are respectively counted by registers formed in an RAM (4). When one of these start numbers reaches a set value, the receiving circuit (11) selected is switched to another receiving circuit (12) having a higher threshold value and requiring no bias current, or the threshold value of the receiving circuit is increased by an inhibit circuit so that the internal power consumption of the card is suppressed, and the card is not affected by external noise. In addition, when the value of one of the registers reaches a set value, the external device informs the user of the fact that the value reaches a set value, using sound or a display.

Abstract: A method for optimizing the pacing and processing of inbound calls and outbound calls. Statistics are generated concerning inbound calls and outbound calls, and concerning the performance of each agent for inbound calls and outbound calls. Separate statistics concerning inbound calls and outbound calls allow a more accurate prediction of call pacing and handling requirements and of the availability of an agent so as to maximize the productivity of each agent and control the on-hold time of inbound and outbound calls. Each trunk line is designated for inbound calls or outbound calls and the status of each trunk is monitored. If all of the trunks allocated to inbound service are in use then some of the trunks designated for outbound service are redesignated for inbound service. If more than a predetermined number of trunks designated for inbound service are not in use then some of these trunks will be redesignated for outbound service. Therefore, the rate of answering of inbound calls and the rate of placement of outbound calls, and the allocation of trunks between inbound calls and outbound calls are driven by the frequency, duration and number of calls and user-selectable options.

Abstract: An electrical power converter (10) includes both DC and AC power terminals (26,27; 19) which are respectively connected to a DC current source (42) and an AC voltage source (16), the latter comprising the grid of an AC power utility. A capacitor (24) is coupled to the AC terminals along with a load (22). A control and gating circuit (30) is coupled to the converter for supplying control signals for the thyristors (11) of a converter bridge included in the polyphase converter. When disconnected (at 20) from the utility grid, a relatively fast acting control loop (44) is coupled to the control and gating circuit and is responsive to the current flowing in the capacitor and an AC reference voltage (at 52) to accommodate the current source characteristics of the converter for maintaining an output voltage of substantially constant amplitude across the AC terminals. A second and relatively slower acting control loop (46) is also coupled to the control and gating circuit via the fast acting control loop and is responsible to the AC voltage across the capacitor and the load for providing regulation of the voltage across the AC terminals during steady state operation. <IMAGE>

Abstract: Contacts to the gate electrode (7) of a first field-effect transistor and the source/drain region (5) of a second field-effect transistor are formed by forming four insulating layers (9,11,13,15), adjacent layers having different etching characteristics (e.g. alternative oxide and nitride layers) etching windows in the top two layers (13,15), forming sidewalls (21) on the windows, etching windows in the next layer (11), using the sidewalls as a mask, and then etching windows in the bottom layer (9) using the previously etched layer (11) as a mask. A conductor layer (e.g. polisilicon or silicide) is then put down and makes contact through the windows. The size of the windows formed in the bottom layers, and thus of the contacts, is smaller than the size of the windows etched in the upper layers, and may be smaller than the lithographic limit.

Filed: 1991-09-13
Abstract: A latch circuit employs a feedback arrangement comprising a transmission gate circuit (123) that conducts only when the output node (122) is in a mid-voltage state. At the onset of a metastable state, the feedback arrangement forces a receiving node (102) into its previous stable state, thereby forcing the output node into a stable state. This eliminates or reduces the possibility that the latch could remain hung for an indefinite period in a metastable state.

Abstract: The present invention describes a method of controlling the head pressure in a refrigeration or air conditioning system in order to maintain the internal discharge pressure and discharge line pressure substantially equal. The method consists of the steps of measuring the suction pressure of the working fluid with pressure sensing device (116), calculating the internal discharge pressure of the working fluid by multiplying the suction pressure by the internal pressure ratio of the compressor (100), measuring the discharge line pressure of the working fluid with pressure sensing device (122) and then comparing the internal discharge pressure to the discharge line pressure. If the difference between the internal discharge pressure and discharge line pressure is greater than some allowable tolerance, the capacity of the condenser (104) is adjusted by controller (128) to equalize these two pressures.
