Title: Planarization of integrated circuit surfaces through selective photoresist masking
IPC: H01L21/762
Filed: 1975-06-12
Abstract: An integrated circuit substrate surface, particularly a surface of electrically insulative material, having a pattern of elevated areas and a complementary pattern of unelevated areas is planarized by forming the photoresist pattern in registration with the pattern of unelevated areas, the photoresist pattern having narrower lateral dimensions than said elevated pattern whereby registration is facilitated, flowing the photoresist pattern to laterally expand the photoresist to cover and thereby mask the unelevated areas, and etching to lower the elevated areas which remain uncovered by the photoresist.

Title: Method and apparatus for executing sequential data processing instructions in function units of a computer
IPC: G06F7/00
Filed: 1976-05-12
Abstract: In a computer which includes function units interconnected by a bus system there is a first type of instruction which selects one function unit and orders the performance of an internal function and a second type of instruction which selects two function units for the interchange of data through the bus system and orders the data receiving function unit to perform an internal function using the transferred data. The execution period of the second instruction type has a first part during which the first function unit is ordered to transmit data, a second part during which the data are transferred to the bus system and a third part during which the other function unit receives the transferred data. The design of the bus system makes possible the simultaneous performance of the second and third parts. The instructions are successively obtained by a fixed-cycle reading of an instruction memory and are transferred therefrom through the bus system to the function units. The execution period for an instruction of the first type and for the first part of an execution period part of the second type, respectively, are finished during the read phase of that instruction. The simultaneous performance of the second and third part of an execution period for an instruction of the second type are finished during the read phase of the following instruction.
Patent ES-448412-A1 (ES)
Title: Phase imbalance detection circuit
IPC: H02H3/12
Filed: 1976-05-31
Abstract: A phase imbalance logic module for a solid state motor protection system for a three-phase motor. Three-phase line currents are converted to corresponding voltages and rectified. The resultant output voltage is a poorly regulated DC voltage having a ripple of approximately 4% during normal operating conditions. In the event of a phase failure, even if not total, the corresponding ripple percentage increases. The phase imbalance logic network senses ripple and provides an output signal to trip a protective circuit breaker if the component of ripple becomes significantly large.

Title: Sulfolanyl-bearing organosilicone polymers
IPC: C07F7/08
Filed: 1976-06-28
Abstract: A particular class of sulfolanyloxyalkyl-substituted organosilicone polymers are provided which comprise chemically combined monofunctional siloxy units (Mo) and difunctional siloxy units (Do) and, for every two moles of Mo, an average of from about two to about 100 silicon-bonded sulfolanyloxyalkyl groups (Q) and an average of from about 2 to about 30 silicon-bonded E DEG groups where E DEG is hydrogen or a polyoxyalkylene block (E). When E DEG is hydrogen, the polymers are sulfolanyloxyalkyl-substituted polyalkylsiloxane hydrides and, when E DEG is E, the polymers are sulfolanyloxyalkyl-substituted polyalkylsiloxane-polyoxyalkylene copolymers. The monofunctional siloxy units encompassed by Mo have at least two alkyls bonded to the respective silicon atoms thereof and the difunctional siloxy units encompassed by Do have at least one alkyl bonded to the respective silicon atoms thereof, the remaining group bonded to silicon of said Mo and Do units being alkyl, Q or E DEG . The sulfolanyloxyalkyl-modified polyalkylsiloxane hydrides are especially useful as hydrosilation and condensation agents such as in forming the correspondingly modified polyalkylsiloxane-polyoxyalkylene copolymers of the invention. The copolymers in turn find particular application in the manufacture of cellular urethane products including urethane foam containing a flame-retardant.

Patent ES-459317-A1 (ES)
Title: Fast acting two-way valve
IPC: F16K11/16
Filed: 1977-05-31
Abstract: A valve assembly having a small volume cavity formed therein which communicates with two valves, one of which is closed completely before the other one is opened and vice versa. An actuating mechanism holds a valving member in one of the valves in an opened condition to thereby maintain a fluidic path through the one valve and the cavity. The other valving member at this time lies in a closed position preventing communication between this valve and the cavity. The actuating mechanism when actuated moves away from the valving member in the open valve allowing the open valve to close completely. The fluidic path through the one valve is thereby broken. A second fluidic path is made when the actuating mechanism moves the other valving member to an opened position.
Patent ES-461343-A1 (ES)
Title: Stylus printer impact energy control
IPC: B41J2/30
Filed: 1977-08-04
Abstract: In a magnetically operated matrix printer a circuit makes a decision when a magnet is actuated. The decision is whether or not the relevant magnet has already been actuated during the printing of the previous column of the matrix character being printed. When it has not been actuated, it is actuated with a larger quantity of energy (longer pulse). Thus the operation of the printer is in "resonance" with the mechanical movements of the magnet armature.

Patent ES-8202984-A1 (ES)
Title: Rotary switch with an automatic re-setting mechanism
IPC: H01H83/12
Filed: 1981-04-23
Abstract: A rotary switch has a control shaft (8) controlling electrical contacts (not shown). On being moved from the "OFF" position as illustrated towards an "ON" position by turning clockwise (arrow 9), a ramp (21) on a cam (2) engages a cam follower (41) mounted on a first lever arm (3). The first arm is held in position against the thrust of the cam follower's bias spring (42) by a catch (31) engaging a bearing surface (51) of a second lever arm (5). Similarly the second lever (5) is held in position by a spring (52) urging it against the moving part of an electromagnet (7). The electromagnet is shown in its powered position with spring (61) compressed thereby. Turning the shaft also winds up a return spring (not shown) tending to urge the shaft towards the "OFF" position. The shaft is held in the "ON" position by the cam follower (41) engaging in a notch (20) in the cam. When power to the electromagnet fails (i.e. normally the power that is switched by the switch), its moving part is thrust by the spring (61) in the direction of arrow 91. This disengages the catch (31) from the bearing surface (51), allowing the first lever to move away from the shaft, and hence disengaging the cam follower from the notch (20). The shaft is then free to return to its "OFF" position under the action of its return spring.
