Abstract: An electrically alterable non-volatile memory device is disclosed. In the device architecture of the memory device, control gates are formed, divided corresponding to the blocks and interconnected independently within each block, to further be connected to a metal gate line through block select MOS transistors which are formed on a semiconductor substrate between the blocks. All gate electrodes of the block select MOS transistors which are connected to the control gates interconnected as above within each block are further connected each other. These block select transistors can be controlled by applying erase block signals such as, EBS0, EBS1 and so on, to respective transistors. In addition, the control gates are further connected to a decoder such that some of these control gates may be selected through metal control gate lines.

Abstract: A semiconductor memory device includes a plurality of memory arrays which are provided on a semiconductor chip, the memory arrays including a predetermined memory array. A plurality of bias-voltage supply circuits respectively supply operating voltages to the memory arrays, the bias-voltage supply circuits including a predetermined supply circuit which supplies an operating voltage to the predetermined memory array. A control circuit controls the bias-voltage supply circuits respectively when a command is externally transmitted to the control circuit. The control circuit outputs a disable signal to the predetermined supply circuit in response to a partial-sleep-mode set command externally transmitted thereto, the disable signal causing the predetermined supply circuit to stop supplying the operating voltage to the predetermined memory array.

Abstract: A rescue aiding apparatus carried by a lost person includes a radio receiver for receiving a radio signal, a radio transmitter for transmitting a radio signal, and a power supply for supplying working power. When the radio receiver receives a radio search signal transmitted from a search party, the power supply supplies operating power to the radio transmitter. The apparatus thereby becomes fully operable, and the radio transmitter transmits a radio signal as a response signal for enabling a search for the lost person needing protection. Even when the lost person is unable to make a rescue request, the search party can, on their own will, place the rescue aiding apparatus carried by the lost person in a fully operable state to notify the search party of a current position of the lost person.

Abstract: A method for testing causative bacterial species of food poisoning which is characterized by using two oligonucleotide primers that hybridize to opposite strands of bacterial DNA specifically, and flank a unique region in the target DNA and amplifying the specific fragment of the bacterial DNA, comprising the steps of:(a) hybridizing the primer to specific gene sequence of bacteria in a sample, extending the hybridized primer with deoxynucleotide triphosphates (dATP, dCTP, dGTP, and dTTP), and resultantly making the double strand nucleotide;(b) where the primer extension products are cleaved into each single strand of nucleotide by certain external force such as heat, pH and so on, one single strand functioning as a template for nucleotide extension with a primer of the other strand;(c) repeating a series of cycles involving cleavage of primer extension products, primer hybridizing, extension of the hybridized primers to amplify the specific fragment of DNA, and detecting the amplified DNA fragment; and(d) as
