Title: Method for desulphurizing exhaust smoke
Inventor: UKAWA NAOHIKO
IPC: B01D47/00
Filed: 1991-06-17
Abstract: A method for desulphurising an exhaust smoke which comprises the steps of leading the exhaust gas containing fly ash to a gas absorbing step (1), removing SO₂ and the fly ash from the exhaust gas by use of an absorbing solution slurry containing calcium carbonate as an absorbent in the gas absorbing step, and blowing air into the absorbing solution slurry circulating through the gas absorbing step (4) to oxidise it and to thereby produce gypsum. The method is characterised by drawing a portion of the absorbing solution slurry and directing it to a magnetic field to separate and recover the fly ash from the absorbing solution slurry, and then returning to the gas absorbing step a portion or all of the absorbing solution slurry from which the fly ash has been separated. 
     The invention sets out to reduce the amount of fly ash and hydrogen fluoride in an exhaust gas, whilst maintaining the activity of calcium carbonate as an adsorbent. In addition, the invention sets out to allow a high-purity gypsom to be recovered.

Abstract: A receiver is mounted on an automobile telephone or similar mobile station which is included in a cellular mobile radio communication system. The receiver has a high frequency amplifier (3) for amplifying a received input wave, and a mixer (5,10) for converting the received input wave to an intermediate frequency. The gain of the amplifier (3) or that of the mixer is changed on the basis of the level of the field strength (14) of the received input wave and whether or not the mobile station is communicating with a base station. The receiver enhances the reception sensitivity characteristic at locations where the reception field strength is low or the intermodulation distortion characteristic at locations where the field strength is high and intermodulation distortions occur.

Abstract: An exploding foil bubble activated detonator, adapted for use in a perforating gun, includes an exploding foil (20b), the exploding foil (20b) including a neck section (20b2) which vaporizes when a current of sufficient magnitude and duration flows therethrough, a layer (22) of polyimide material deposited over said foil (20b), and a spacer layer (24) deposited over said layer (22) of polyimide material, the spacer layer (24) including a guiding hole (24a) disposed directly over the neck section (20b2) of the foil (20b). When the current flows through the neck section (20b2) of the foil (20b), a turbulence is caused to occur directly above the neck section (20b2). This turbulence causes a portion of the polyimide material to expand to form a bubble (22a). The bubble (22a) is shaped and sized by the guiding hole (24a) in the spacer layer (24) which is disposed directly over the neck section (20b2) of the foil (20b). The shaped and sized bubble (22a) in the polyimide material impacts an explosive (26b) thereby detonating the explosive (26b). A selective gun firing system may include the bubble activated detonator and functions to allow an operator to selectively fire, in a predetermined sequence, a plurality of perforators in the perforating gun, such as from bottom gun to top gun. A hall effect sensor disposed in a well truck is connected to a wireline to which the perforating gun is connected and senses a current in the wireline. A novel safety barrier is inserted into a hole in a barrel of a prior art exploding foil initiator (EFI) detonator for blocking a flying plate flying in the hole and thereby preventing accidental detonations of the EFI detonator.

Abstract: Improved methods of programming floating gate memory devices such as MOS EPROMs having a gate, a floating gate, a read channel, and a write or programming channel. Potential is applied to the read channel (which is normally inactive during programming) in order to increase the voltage induced on the floating gate by the programming voltage applied to the gate. This makes it possible to reduce the programming voltage which must be applied to the gate, to reduce the time required to program the device, or to achieve some measure of both of these benefits.

Abstract: In a first processing mode for a first communication request, a communication processing unit (20) responds to a communication request signal from a communication terminal (10) to acquire an authentication key Ka corresponding thereto from a storage (30), generates pieces of enciphered authentication information Xai and Xbi enciphered by the authentication key Ka of the communication terminal and an authentication key Kb of the communication processing unit, respectively, and random information Yi and transmits these pieces of information Xai, Xbi and Yi as an authentication request signal to the communication terminal. The communication terminal sends, as an authentication response signal, information Ka[Yi] obtained by enciphering the received random information Yi with the authentication key Ka, back to the communication processing unit, and at the same time, the communication terminal stores the received enciphered pieces of authentication information Xai and Xbi. The communication processing unit verifies the authentication response signal by use of the authentication key Ka. 
     In a second processing mode, the communication terminal transmits previous enciphered authentication information Xb(i-1) as a communication request signal to the communication processing unit and deciphers previous information Xa(i-1) to generate an authentication key Kci. The communication processing unit deciphers the received enciphered authentication information Xbi to generate a deciphered authentication key Kci and transmits to the communication terminal an authentication request signal containing newly generated pieces of enciphered authentication information Xai and Xbi and the random information Yi. The communication terminal stores the received pieces of enciphered authentication information Xai and Xbi and enciphers the random information Yi by the authentication key Kci and sends it as an authentication response signal Kci[Yi] to the communication processing unit, which verifies the authentication response signal by the deciphered authentication key Kci.

Abstract: A digital video tape recorder operates in either a standard mode or a long play mode. In the long play mode, the tape speed is reduced so that longer recordings may be made than in the standard mode. In order to overcome the problem of crosstalk between tracks on the tape, which arises if the tape is merely slowed, video signals to be recorded are compressed by a factor corresponding to the speed reduction of the tape and also, the rotational speed of the head drum (100) is reduced by the same ratio as the tape speed. As a result, the widths of the tracks on the tape are the same in both the standard and long play modes.
