Title: Microcomputer system employing address offset mechanism to increase the supported cache memory capacity
Inventor: BEGUN RALPH M
IPC: G06F12/08
Filed: 1990-05-09
Granted: 1996-04-09
Abstract: The capacity of cache memory supported by a cache controller can be increased by offsetting the relationship between CPU address output terminals and address input terminals of the cache controller and correspondingly doubling the cache line size. In some cases, additional logic generates a hidden memory cycle so as to fetch from memory that number of bytes equal to the new line size regardless of the width of the data bus.  The hidden memory cycle is initiated by a read miss and further logic generates a memory address which is not generated by the CPU. The hidden memory cycle is maintained transparent to the CPU and cache controller by inhibiting the change in a READY signal until completion of both the normal memory cycle and the hidden memory cycle.

Title: Piezo electronic horn
Inventor: BUYAK WILLIAM P
IPC: G08B3/10
Filed: 1991-02-01
Granted: 1995-05-16
Abstract: The invention provides an electronic horn for an alarm circuit of the type in which the d.c. power supply for the horn will be of a particular polarity to indicate an alarm condition. The circuit provides a piezo sounder connected across the terminals of the power supply, an inductor connected in parallel with the piezo sounder to form a tank circuit therewith and current modifying means connected in series with the tank circuit to modify the current through the tank circuit in response to the output of an R/S flip-flop which is periodically set by a clock signal at a frequency corresponding to the frequency desired for the fundamental audible tones of the sounder. The duration of the clock output pulse which makes the modifying means conductive must be such that the capacitance of the sounder is charged by the supply before the output of the clock permits a change of state in the flip-flop to make the modifying means nonconductive. A source of reset signals is connected to detect the current in the series circuit and is operable to produce a reset signal which will cause the change of state to thereby cut off the current through the tank circuit when the current detected exceeds a predetermined value after charging the sounder capacitance, at which time the tank circuit will go into a decaying oscillation to provide overtones in the sound output.

Abstract: In an optical amplifier for amplifying a signal light by propagating the signal light and a pumping light in a rare earth element doped fiber (2) doped with a rare earth element, a diameter of a rare earth element doped portion of the rare earth element doped fiber (2) is gradually reduced in a direction of propagation of the pumping light.  With this construction, an adverse rare earth element doped area which does not contribute to optical amplification but rather attenuates the pumping light can be eliminated to thereby provide an optical amplifier suitable for an increase in amplification efficiency.
