Abstract: Two nucleotide sequences encoding two different polypeptides found in yeast trehalose synthase have been isolated and cloned. The coding sequences can be inserted into suitable vectors and used to transform host cells. The transformed cells will produce increased amounts of trehalose compared to the untransformed wild types and have increased tolerance to a variety of stresses, in particular to decreased availability of water. The invention may be used to improve the stress tolerance of organisms, to increase the storage life of foodstuffs and to produce trehalose economically on an industrial scale in an organism (e.g, baker's yeast) that is a traditional and safe foodstuff.

Abstract: Method and apparatus are disclosed for reproducing digitized voicemail (verbal) message signals destined for a recipient at various different text reproducing devices. Upon accessing a mailbox storing a voicemail message and providing a predetermined feature access code, the recipient is able to have a digitized voicemail message signal converted into an ASCII text signal and reproduced at an electronic display device, a printing device, and/or a facsimile device. The voicemail apparatus includes a voicemail messaging system for receiving and storing voicemail messages received from a public/private voice network, a voice-to-text processing system, a file server, and a variety of different text reproducing devices. The voice-to-text processing system converts a voicemail message from a digitized voice message signal into an ASCII text message signal which is stored in the file server. The file server distributes each stored text message signal to the proper text reproducing device in response to a user of the voicemail apparatus entering a predetermined feature access code associated with that text reproducing device either to the voice messaging system or the file server. The apparatus can also be arranged to automatically reproduce each voicemail message for a predetermined recipient at a predetermined one of the text reproducing devices. <IMAGE>

Abstract: Pulse frequency modulation is used to control brakes and clutches 10 which are operated by fluid pressure actuators 22 controlled by electrically actuated solenoid valves 28. Short pulse periods for all duty cycles are generated by feedback from the solenoid valve 28 or from the actuator 22. In one circuit an electrical control 30 triggers a flip-flop 38 which starts solenoid current. Solenoid movement results in back-emf and its effects on the solenoid flux field or current is detected and used as a feedback signal to reset the flip-flop 38 to thereby turn off the current as soon as the valve 28 is operated. In another circuit, a computer control 30' emits a command for a certain pulse period. Actuator pressure or position is monitored to produce a feedback signal to the computer. If the signal is not received, the pulse period is increased for the next pulse command so that a sufficient pulse period will be found. If the magnitude of the actuator response exceeds a threshold, the pulse period is decreased for the next pulse command. Pulse width modulation may also be improved by the same technique for minimizing the pulse period at the lowest duty cycles and yet assuring actuation. <IMAGE>

Abstract: A method of reducing the nitrogen oxide level in the flue gases issuing from combustion units by introduction of reducing agents into contact with gases containing nitrogen oxides in first and second reducing stages, is provided. The first reducing stage is a non-catalytic stage (e.g. at temperatures over 800 DEG  C.), while the second stage is a catalytic stage (e.g. at temperatures of about 300 DEG -400 DEG  C.). A steam generation boiler with improved nitrogen reduction facilities is also provided. The amount of nitrogen oxides in the hot gases is reduced in the combination of the first and second reducing stages while producing steam in a steam generation boiler system, thus resulting in gases essentially free from nitrogen oxides while eliminating the possibility of NH3 (or other reducing agent) slip in the exhausted flue gases. Heat transfers in a convection section as used to establish stabilized temperature conditions for catalytic reduction.

Title: 'terminal repeat'- amplifikation

Granted: 2001-11-08
Abstract: This invention relates to a process for amplifying a specific nucleic acid sequence or its complement at a relatively constant temperature and without serial addition of reagents. The process provides in a single reaction medium an RNA polymerase, DNA polymerase, a ribonuclease that hydrolyses RNA of an RNA-DNA hybrid without hydrolysing single or double-stranded RNA or DNA, and ribonucleoside and deoxyribonucleoside triphosphates. The process then provides an RNA first template in the reaction medium. The RNA first template comprises a sequence complementary to a specific nucleic acid sequence, minus-sense sequences for a promoter and initiation site that are recognized by the RNA polymerase, and a 5'-terminal sequence that is complementary to at least the minus-sense sequence of the initiation site. Thus, the RNA first template has an inverted repeat sequence which could fold into a 5'-terminal stem-loop structure. The DNA polymerase uses the RNA first template to synthesize a DNA second template that together comprise an RNA-DNA hybrid. The DNA second template has plus-sense sequences of the promoter and the initiation site, and a 3'-terminal priming sequence that is complementary to the plus-sense sequence of the initiation site. The ribonuclease then hydrolyses an RNA which comprises the RNA-DNA hybrid, allowing the 3'-terminal priming sequence to hybridize to the plus-sense sequence of the initiation site in the DNA second template. The DNA polymerase then uses the DNA second template to synthesize the promoter by extending the 3'-terminal priming sequence of the DNA second template. The resulting partially double-stranded DNA has a promoter oriented toward the apex of a stem-loop structure. The RNA polymerase then recognizes the promoter and transcribes the DNA second template, thereby providing copies of the RNA first template. The process thereafter maintains the reaction conditions for a time sufficient to achieve a desired amplification of the specific nucleic acid sequence or its complement. This invention includes a kit containing the reagents of this invention.

Abstract: A buried layer which is highly doped and implanted with high energy in a lightly doped isolated well in which an array of flash EPROM cells are provided. The buried layer is doped with the same conductivity dopant as the well in which it is provided, for example a p<+>- type buried implant is provided in a p-type well. The buried layer enables channel size of the flash EPROM cells to be reduced providing a higher array density. Channels of the flash EPROM cells are reduced because the buried layer provides a low resistance path between channels of the flash EPROM cells enabling erase to be performed by applying a voltage potential difference between the gate and substrate of a cell.

Abstract: A motorcar having a man power driving system in which a driving force by man power is applied through a change gear (25) to a wheel to rotate, and a motor driving system in which the wheel is directly rotated by a driving force of a motor (49). The man power driving system is equipped with a torque detector (44) for detecting a man power driving force so as to drive the motor according to a magnitude of the man power driving force detected by the turque detector. A particularly durable change gear is not required to use, and thus a common change gear for bicycle can be used, thereby exhibiting an effect such that construction is made simplified.
