Title: Format identification method and character recognition device
Inventor: GOTO HIROHISA
IPC: H04M11/00
Filed: 1997-06-17
Abstract: PROBLEM TO BE SOLVED: To provide a recognition device which can use a document where an ID number is not described and which can precisely identify a format at high speed by identifying the format corresponding to calling source data through the use of calling source data. SOLUTION: A reception part 12 receives the picture signal of a facsimile signal transmitted through a communication line and the telephone number of the calling source as calling source data specifying the calling source of the picture signal. The reception part 12 stores the picture signal in an inner image memory and sends the telephone number to a format identification part 14. The format identification part 14 selects and identifies the format corresponding to the telephone number of the calling source from the registered format. A control part 18 calls the format control program of the identified format from a format control program storage part 16 and sends it to a character segmentation part 20. The character segmentation part 20 segments the character from the picture signal and a character recognition part 24 recognize the character.

Title: Thrust protecting apparatus of steam turbine
Inventor: KATAYAMA AKIRA
IPC: F01D21/16
Filed: 1989-06-22
Abstract: PURPOSE:To prevent malfunction of a thrust protecting apparatus when an earthquake occurs by a method wherein the output from a signal determining unit to which the output from an earthquake sensing circuit and trip signals from pressure switches are input is regarded as final trip signal. CONSTITUTION:Trip signals Pa, Pb generated by pressure switches 14a, 14b are input to a signal determining unit 20 via an OR circuit 23. An output signal T from an earthquake sensing circuit 22 is input to the signal determining unit 30 as a NOT signal T' via a NOT circuit 24. The signal determining unit 30 comprising an AND circuit 21 determines operation of a thrust protecting apparatus with the trip signal Pa or Pb as a final trip signal only when the trip signal Pa or Pb is output and the NOT signal T' is ON. Thus misoperation of the thrust protecting apparatus to trip a turbine due to deformation of a thrust protecting apparatus installing face or transitional movement of a turbine rotor shaft 16 when an earthquake occurs during plat operation can be securely prevented.

The produced amount of sulfate ions is maximum in a first block 4-I wherein offensive gas is firstly brought into contact with the layers 5 of fillers and gradually reduced toward a fifth block 4-V. Therefor, the respective flow rate controlling valves 12 are adjusted and the amount of washing water sprayed to the layer 5 of filler of the first block 4-I is made maximum. The amount of washing water sprayed toward the fifth block 4-V is successively reduced.

Title: Apparatus for estimating running position of vehicle
Inventor: NASUDA ATSUSHI
IPC: G01C21/00
Filed: 1994-07-14
Abstract: PURPOSE:To provide an estimating apparatus for estimating a running position of a vehicle whereby the kind of a road on which the vehicle is running is estimated more properly with the effective utilization of estimation materials such as a vehicle velocity, etc. CONSTITUTION:Supposing that a vehicle velocity V is larger than or equal to 60km/h and an expressway is included in a proposed road, a predetermined probability of 'coefficient X 1' is set for the expressway after a running distance D becomes larger than or equal to 500m. While D<500m is maintained, a continuous value shown in the graph is set between 0 and 1 to obtain a probability as a multiplied value of the coefficient, and the continuous value. As the D is longer, the probability is gradually approximated to the predetermined probability 'coefficzient X 1'. A running state of V>=60km/h is hence added to make the estimation and evaluation of a running position in accordance with the running distance before the running distance D reaches 500m. Therefore, an effective data to estimate the running position of the vehicle that the vehicle runs at high speeds is made use of in accordance with the state of data, so that an erroneous estimation is lessened.
