Abstract: A dynamic random access memory having a bit line precharge capability is provided with an internally gated RAS signal, such that bit line precharge operation does not being until an internal timing signal is issued indicating completion of the read/write internal timing chains. The external RAS signal is made to transition prematurely into an inactive (or precharge) state, so that the bit line precharge operation necessarily occurs immediately after the internal timing chains are completed. This occurs independent of any circuit fabrication variations or component tolerances.

Abstract: A system is disclosed for remote control of a driver's seat in a vehicle equipped with powder seats but without memory seats function. The system is controlled by remote RF transmitter and auto security system which are responsive to a remote control signal disarming the system. Upon receipt of such signal the system will position the driver's seat on a preselected mode to either initial easy access position or a driver position corresponding to the particular transmitter code. In the event an intrusion is detected while the security system is armed, the system automatically moves the driver's seat to an alarm position closest to the vehicle's dashboard to make it difficult or impossible for an intruder to drive the vehicle.

Abstract: A bubble blowing figure toy having a hollow torso configured with a head portion defining a mouth opening and a squeezable body portion. An operative device is arranged substantially within the torso of the figure toy for generating bubbles from a bubble forming liquid applied to the mouth opening. In response to squeezing of the figure toy, a stream of air is directed toward the mouth opening to facilitate bubble formation into either a large bubble or a series of generally uniform smaller bubbles. The operative device includes a mouthpiece, an air bladder, and an air duct. The mouthpiece is arranged at the mouth opening of the toy and to one end of which the bubble forming liquid is applied. The air bladder generates an air stream, and the air duct connects the air bladder with the mouthpiece. The air duct is configured to inhibit ingestion of bubble forming liquid into the air bladder. A valve in the air duct further facilitates bubble formation.

Abstract: A method of making a thermistor comprising the steps of making a layer of thermistor ceramic material comprised substantially of Mn.sub.2 O.sub.3, NiO, Co.sub.3 O.sub.4, Al.sub.2 O.sub.3, CuO, or Fe.sub.2 O.sub.3, having upper and lower surfaces. A first dielectric material comprised of low K Al.sub.2 O.sub.3 or the like is placed on the upper and lower surfaces of the layer, and then is cut into a plurality of elongated strips. The layer is created by blading a slurrey of the ceramic material to create a plurality of uncured sheets; placing the sheets in superimposed position, and then making the monolithic layers from the sheets by applying heat and pressure thereto, and then firing the monolithic layer with heat of increased magnitude. The strips are encapsulated in an envelope of the dielectric material, and terminal connections comprised of silver, Ni, Sn and Pb are imposed thereon. A thermistor chip or strip comprising an elongated ceramic thermistor body with an outside surface and opposite ends.

Abstract: A motion detecting device comprises an encoder for generating two signals of A phase and B phase, 90.degree. out of phase with each other, when a member being measured is subject to an inclination or swaying. A pulse generation section generates a positive pulse or a negative pulse, depending on the direction of the inclination, at each of the leading and trailing edges of the A phase and B phase signals. An up/down counter counts up or down the positive or negative pulses, respectively, and an inclination detection section outputs an inclination generation signal when the member being measured is sufficiently inclined, in either a positive or negative direction, so as to cause a counter value to be above a first set value or below a second set value.

Abstract: A data generator generates digital data at a sampling time interval .sub..DELTA. T (sampling frequency f.sub.s =1/.DELTA.T), and the three latest items of digital data V.sub.-1, V.sub.0, V.sub.+1 are repeatedly latched successively in three latch circuits every 3.multidot..sub..DELTA. T. A pulse response signal generator outputs unit pulse response signals of period 3.multidot..sub..DELTA. T at the time interval .multidot..sub..DELTA. T, and three multiplying-type DA converters multiply these three unit pulse response signals .phi..sub.0 (t+.sub..DELTA. T), .phi..sub.0 (t), .phi..sub.0 (t-.sub..DELTA.

The outputs of these multiplying-type DA converters are combined into an analog signal S.sub.A, which is delivered as an output.

Abstract: An anti-slagging apparatus for a furnace viewing system removes slag build up deposited on a closed circuit television camera lens tube by occasionally releasing a blast or large volume of air through specially designed ports surrounding the tube containing a furnace viewing lens system.

Abstract: A distraction device is comprised of a hollow container that is divided into a first chamber and a second chamber. An explosive charge capable of producing a loud sound and a brilliant flash of light fills the second chamber. A standard M201 hand grenade fuse is installed in the distraction device so that the fuse is in communication with the first chamber. The fuse initiates the sequential ignition of several combustible compositions in the distraction device. A first combustible composition generates a combustion gas of sufficient pressure in the first chamber to separate the expended fuse from the distraction device before the device explodes. The first composition also ignites a combustible time-delay composition, which in turn ignites a spark-producing composition that detonates an explosive output charge. Separation of the fuse from the distraction device before the explosive charge is detonated prevents the fuse from becoming a lethal projectile.

Abstract: A thermosensitive recording label includes a substrate, a thermosensitive color-forming layer disposed on one side of the substrate, a protective layer disposed on the thermosensitive color-forming layer, a pressure-sensitive hot melt adhesive layer disposed on another side of the substrate and a releasable backing sheet disposed on the pressure-sensitive adhesive layer. The use of a hot melt adhesive layer enables the thermosensitive label to be placed on plastic films without migration of plasticizers in the film from migrating into the color-sensitive layer. The hot melt adhesive not only prevents such plasticizers migration, but enables the labels to be placed on beef products without discoloration of the beef beneath the label.
