Abstract: Method for the treatment, particularly for the sterilization and/or pasteurization, of biological, food and non-food products containing bacterial and spore loads, which involves subjecting each product to an alternating electromagnetic field of predetermined frequency and specific power, for a set time, in which said parameters are determined as a function of the composition and percentage of the loads, so as to destroy them in a substantially complete and uniform manner, keeping the organic and organoleptic properties of the product treated essentially unchanged. Equipment for performing the above-mentioned method comprises means 3; 30; 50 for confining a determinate amount of product (P) to be treated between the armatures 14, 15; 30, 31; 42, 43, 46 of a high-frequency electromagnetic oscillator of a type known per se, and means 20, 60 for regulating the frequency (f) and specific energy of the electromagnetic field generated by the oscillator, as well as the exposure time (t) of the product to the electromagnetic field. <IMAGE>

Title: A data sense circuit for dynamic random access memories
Inventor: KIRIHATA TOSHIAKI
IPC: G06F13/368
Filed: 1996-01-22
Granted: 1996-09-21
Abstract: An improved data sense for a DRAM. Each bit line pair is coupled through a pair of high-resistance pass gates to a sense amp. During sense, the high-resistance pass gates act in conjunction with the charge stored on the bit line pair as, effectively, a high-resistance passive load for the sense amp. A control circuit selectively switches on and off bit line equalization coincident with selectively passing either the equalization voltage or set voltages to the sense amp and an active sense amp load. Further, after it is set, the sense amp is selectively connected to LDLs through low-resistance column select pass gates. Therefore, the sense amp quickly discharges one of the connected LDL pair while the bit line voltage remains essentially unchanged. Thus, data is passed from the sense amp to a second sense amplifier and off chip. After data is passed to the LDLs, the control circuit enables the active sense amp load to pull the sense amp high side to a full up level.
