Title: Voice controlled dialer having memories for full-digit dialing for any users and abbreviated dialing for authorized users
Inventor: FUJISAKI HISASHI
IPC: H04M1/27
Filed: 1988-10-11
Granted: 1992-01-07
Abstract: "Voice Controlled Dialer Having Memories for Full-Digit Dialing for Any Users and Abbreviated Dialing for Authorized Users"     ABSTRACT OF THE DISCLOSURE A voice controlled automatic dialer comprises a speech analyzer for generating a signal representative of characteristic patterns of an input utterance entered through a microphone, and a first memory for storing a plurality of reference signals representative of predetermined characteristic patterns of utterances of dialing numbers and command words, the predetermined characteristic patterns being representative of utterances common to any users. A second memory stores a plurality of reference signals representative of specific characteristic patterns of utterances of dialing names which are defined by authorized users. The output signal of the speech analyzer is compared with the reference signals stored in the first and second memories and an output is generated as representative of least distances between the characteristic patterns of the input and the stored patterns. The result of the comparison is indicated by a synthesized speech or a multifrequency tone to permit users to confirm the validity of the input utterances. A manually operated switch couples the output of the speech analyzer to the second memory when it is desired to store a user-specific dialing name into the second memory after a training process.

Title: Apparatus for shift control in an automatic  transmission
Inventor: AOKI TAKASHI
IPC: F16H61/00
Filed: 1989-02-09
Granted: 1992-09-08
Abstract: Abstract An  apparatus for controlling gear shifting in an  automatic transmission  on a motor vehicle has maximum speed range  cut-off switch  which can manually be turned on and off selectively,  the arrangement being such that the setting of a maximum speed  range in  each  of  the shift ranges is prohibited by  turning  on  the maximum speed range cut-off switch.    When the maximum-speed range cut-off switch is turned  off, speed range shifting is automatically performed dependent on  the traveling states of the motor vehicle in one of the shift  ranges which  is selected by the shift lever shifted to a  corresponding shift  position.  When the maximum speed range cut-off switch  is turned  on, the setting of the maximum speed range is  prohibited in  each of the shift ranges.  In each shift range,  speed  range shifting  is curried out automatically between  the  lowest-speed range and a speed range which is one range lower than the maximum speed  range  dependent  on the traveling  states  of  the  motor vehicle.

Abstract: PREVENTION OF FORMATION OF NICKEL SUBSULFIDE IN PARTIAL     OXIDATION OF HEAVY LIQUID AND/OR SOLID FUELS                  (D#79.140 -F) ABSTRACT     A sulfur-containing heavy liquid hydrocarbonaceous fuel and/or solid carbonaceous fuel with a nickel, vanadium, and silicon containing ash is mixed with a silicon-containing material,  and a copper and/or cobalt-containing material. The mixture is reacted by partial oxidation in a down-flow-ing  free-flow  unobstructed  vertical  reaction  zone  with refractory lined walls at a temperature in the range of about  1800°F  to  2900°F.

Abstract: Methods and compositions are provided for preparing stabilized interferons and for combining stabilized interferon with cigarettes. Special domains of the interferon molecule are recognized by methods which are described. A means for constructing these domains by recombinant DNA technology is detailed. A method for stabilizing natural interferons is also described. A process for combining the stabilized interferon with cigarettes is presented. The combination of interferons and cigarettes is synergistic, especially because interferon effects are magnified at elevated temperatures and because interferon has a preferential effect on tumor cells, but for other reasons as well. The process is not obvious and will be beneficial to a large segment of mankind; those who use tobacco products.

Abstract: In escalators or moving stairways there exists, between the moving step and the fixedly positioned skirt guard, a latent risk of entrapment or catching of the shoe of the passenger, especially when wearing light footwear. The inventive warning devices are arranged at the side uprights or plates of the step of the escalator and induce the user or passenger, by means of a physically and, possibly additionally, by means of an acoustically perceptible signal, to leave the stepped-on danger zone. Each of the warning devices comprising, for example, two swivelingly or pivotably mounted segments is held in a projecting readiness position, through the force of a spring, in relation to the tread surface and the front surface of the step. When the warning device is stepped upon by the passenger, this warning device is pressed into a flush position with respect to the tread surface of the step and in which position a pin, positioned on one of the segments, is pressed against a profiled guide edge of the related skirt guard. The pin thus glides over the profiled guide edge, during the movement of the step, and causes the step to vibrate. Depending upon the shape of the profiling of the guide edge, an additional acoustically perceptible sound or clatter can be generated.
