Title: Preparation of propane sultone
Inventor: NAKAGAMI ATSUSHI
IPC: C07D327/04
Filed: 1982-11-17
Abstract: PURPOSE:To prepare the titled compound, in high yield, with simple operation, by converting the alkali metal salt of hydroxypropane sulfonic acid (abbreviated as HPS) to acid form using an ion exchange resin, and carrying out the dehydrative cyclization of the acid. CONSTITUTION:Pure sodium carbonate and sodium bicarbonate are charged together with water into a reaction vessel, and made to react with equimolar amount of sulfur dioxide gas blown into the vessel to obtain fresh sodium bisulfite. A reaction initiator is added to the product, and allyl alcohol is added dropwise thereto to obtain an aqueous solution of HPS sulfonic acid sodium salt almost free from inorganic salts. The solution is passed through a strongly acidic cation exchange resin such as Amberlite IR-12OB to obtain an aqueous solution of HPS. The objective propane sultone can be obtained by concentrating the solution with heat in a vacuum of <=40mm.Hg in a flow-down thin film evaporator made of glass, and subjecting the product to the dehydrative cyclization at 130- 150 deg.C.

IPC: H04L7/00
Filed: 1989-08-04
Abstract: PURPOSE:To prevent data slip at clock changeover by providing 2 stages of clock interrupt detection circuits and phase-locking an output of a system selected at present with an output of a system to be selected after that before the output of a current phase locked loop into the output of a standby phase locked loop. CONSTITUTION:When an active (N system) input clock is interrupted due to a fault of a transmission line or the like, a clock interrupt detection circuit 7 supplies a detection signal output to a SEL 8 and a CONT 13. The SEL 8 is switched from the clock input side of the N system into the output clock of the E system PLL 12. Moreover, the SEL 14 is switched from the input side of the PLL 9 (N system) into the input side from the PLL 12 (E system) and the output of the PLL 12 is outputted from the SEL 14. As a result, two stages of clock interrupt detection circuits are provided to phase-lock the output of the PLL 9 of the system (N system) selected at present into the output of the PLL 12 of the system (E system) going to be selected before the SEL 14 selects the output of the PLL 9 into the output of the PLL 12 thereby preventing the data slip at the clock switching in an opposite station.

Title: Person identification method and apparatus
Inventor: HARUTOUITSUHI EE RIYURU
IPC: G07C11/00
Filed: 1982-11-19
Abstract: A method and an apparatus are disclosed for identifying an individual through a combination of both speech and face recognition. The voice signature of an interrogated person uttering a key word into a microphone is compared in a pattern matcher with the previously stored voice signature of a known person uttering the same key word to obtain a first similarity score. At the same time, when a key event in the utterance of the key word by the interrogated person occurs, a momentary image of that person's mouth region onto which a grid pattern has been projected is optically recorded and compared with the previusly stored corresponding momentary image of the same known person to obtain a second similarity score. The two similarity scores are analyzed to verify that the identity of the interrogated person is that of the known person.

Title: Photosensitive body
Inventor: IINO SHUJI
IPC: G03G5/06
Filed: 1985-09-13
Abstract: PURPOSE:To provide an excellent charge transfer characteristic and charge holding power and to obtain a good image by having a plasma-polymerized PE film as a charge transfer layer. CONSTITUTION:Charge carriers are generated in a charge generating layer 3 and electrons neutralize surface charge when this photosensitive body is subjected to positive electrostatic charge, then to image exposing. On the other hand, holes are assured by the excellent charge transfer characteristic of the plasma-polymerized PE film 2 and are transferred to the substrate 1 side. a-Si which is not particularly subjected to a polarity adjustment is used for the charge generating layer and the plasma-polymerized PE charge transfer layer is preferably adjusted relatively to a P-type when the charge transfer layer is used with the positive charge. More specifically, the a-Si itself is of a weak N-type or is intrinsic and therefore, the a-Si prevents the injection of the positive charge from the surface. The plasma-polymerized PE film layer 2 adjusted to the P-type permits the easy transfer of the holes.

IPC: G01T1/29
Filed: 1986-08-30
Abstract: PURPOSE:To enhance detection sensitivity and a response speed, by forming an air stream going to an anode from the opening part of a cathode. CONSTITUTION:When a specimen S is arranged below the opening part 1a of a cathode and irradiated with ultraviolet rays, low speed electrons are dis charged from the surface of the specimen S. Said low speed electrons are carried by the air stream F generated by an air stream generator 15 to be sucked in the opening part 1a and attracted to an anode 4 by the action of the electric fields formed by the anode 4 and grid electrodes 7, 8 to generate discharge. Herein, the anode 4 generates potential drop and this potential drop becomes a pulse signal through a condenser 11 and is amplified by an amplifier 12 to be counted by a counter 16 and the generation frequency of the low speed electrons or the number thereof is displayed on a display device 17. Said pulse signal is inputted to the first and second pulse generators 18, 19 and the voltage from the generator 18 raises the potential of the electrode 7 to stop discharge and the cations in the vicinity of the anode are re-bonded to the electrons to be neutralized. A pulse is generated from the generator 19 to lower the potential of the electrode 8 and cations fly out from the opening part 1a to prevent the surface of the specimen S from receiving an impact.
