Abstract: PAIRED LEAST RECENTLY USED BLOCK      REPLACEMENT ALGORITHM                   ABSTRACT OF THE DISCLOSURE           A set associative cache buffer organized with 2n blocks per set requires only 2n-1 age bits for determining the replacement block within a set.  When the cache buffer is addressed and the data sought is not found therein, the age bits determine which block of data in the set should be replaced with new data from the main memory.  The block replaced may be either the least recently used block or one of the two least recently used blocks.  The replacement logic is such that the buffer may be expanded from two to four blocks per set with minimal impact on the replacement logic. In addition, provision is made for disabling faulty blocks thus allowing the cache buffer and main memory behind it to be utilized in a degraded mode.

Abstract: HUMIDITY DETECTING APPARATUS     Abstract of the Disclosure This invention is directed to an apparatus capable of stably detecting humidity.  More particularly, to stably detect the humidity in the atmosphere where tem-perature, relative humidity or wind flow vary.  The humidity detecting apparatus converts the resistance variation, due to humidity, of a humidity-sensing resistor into voltage variations to draw out the voltage variations, thereby to differentiate the voltage variation with a differentiation circuit and thereafter to compare the differentiation output with a set value.  Therefore, steam leakage from a high pressure, high temperature steam supply pipe or the relative humidity inside a microwave oven can be easily, automatically detected.  The apparatus is quite simple in design and construction and can be manufactured quite inexpensively.

Abstract: THIN FILM MAGNETIC HEAD ASSEMBLY                  ABSTRACT OF THE DISCLOSURE     A thin film magnetic head assembly has a multi-turn electrical conducting coil, which is formed by depo-sition in an elliptical pattern.  By virtue of the elliptical pattern, the coil turn portions between the back gap closure and transducing gap of the thin film head are relatively narrow, whereas the coil turn portions furthest from the transducing gap are widest. Corners and sharp ends are eliminated.  Electrical resistance effects are thereby minimized and signal output is enhanced.

Abstract: ABSTRACT OF THE DISCLOSURE   This invention provides for methods and systems for measuring the dielectric constant of an earth formation.  In a preferred embodiment, an alternating current is passed through a portion of the formation and a reference resistor in series with the portion.  The capacitance and the di-electric constant of the portion may be determined from the phase difference between the voltage across the reference resistor and the voltage across the portion.  This phase difference may be obtained by generating a voltage which is in phase with the voltage across the reference resistor, but which has the magnitude of the voltage across the portion.  To obtain the phase difference by an alternate digital method, the voltage across the referenced resistor and the voltage across the portion are each transformed into a square wave signal.  The two square wave signals are then compared to obtain the sign and the magnitude of the phase difference between the two square waves.  In an alternate preferred embodiment, an alternating current is passed through the portion of the earth formation and through a capacitor and a resistor connected in series with the portion.  The first DC signal is generated by filtering out the high frequency components from the product of the voltages across the capacitor and across the portion.  A second DC signal is generated by filtering out the high frequency components from the product of the voltages across the referenced resistor and across the portion. The phase difference between the voltage across the portion and the current through the portion may be determined, from which the capacitance and the dielectric constant of the portion may then be calculated.
