Title: Condenser sea water leakage continuously monitoring method
Inventor: HORIKAWA MINORU
IPC: F01D25/30
Filed: 1994-03-31
Abstract: PURPOSE:To easily discover leakage of sea water early by providing a step of taking a sample from a boiler or a condenser, a step of separating the sample into a component to be detected and the other components by using eluate and separating column, and a step of detecting the separated component to be detected by a detector. CONSTITUTION:A sample water shut-out valve 5 is opened at the time of measuring for monitoring leakage of sea water, and sample water is taken out from a sample taking-out line by a sample taking-out pump 7. The sample water may be taken out from a condenser 6, a boiler feed water, and the like. The sample water is supplied into a sample taking-out apparatus 9 after suspended solid is eliminated by a filter 8. The sample water which is taken out in the sample taking-out apparatus 9 is supplied to a protect column 11 and a separating column 12, and separated into each negative ion. Chloride ion which is a component to be detected for sea water leakage is taken out from the separating column 12 earlier than the other negative ion. It is thus possible to easily discover leakage of sea water early, and it is possible to carry out early treatment for leakage of sea water.

Title: Superlattice avalanche photodiode
Inventor: WATANABE ISAO
IPC: H01L31/107
Filed: 1991-03-28
Abstract: PURPOSE:To obtain an avalanche photodiode which has photosensitivity in a wavelength band of 1.55mum, a high ionization ratio alpha/beta, low noise characteristics, and high speed response characteristics. CONSTITUTION:A tunnel barrier layer 23 for positive holes of about 25 A in thickness which is available for tunnel transmission of positive holes is arranged at a position of mean free path (20-30Angstrom ) on the multiplying electric field intensity of positive holes apart from a barrier toward the outlet side of positive holes 26 of a well layer 22 of a superlattice avalanche multiplying layer. In the vicinity of the positive hole outlet of an InA As/InGaAs based superlattice quantum layer, positive holes move by 50Angstrom  on account of tunnel transition and non-scattering transmission under an electric field of -400kv/cm. As a result, positive holes can pass a barrier by obtaining energy equal to valence band discontinuity amount Ev=0.2eV. Thereby the pileup of positive holes on the well layer is relieved, so that wide band characteristics of response cutoff frequency of 6-7GHz at multiplication ratio of 10 can be obtained together with low noise characteristics.

Abstract: PURPOSE:To correctly measure a maximum blood pressure value by extracting the sharpest positive peak in the positive peaks of pulse waves to be detected, and deciding the fluid pressure in the cuff corresponding to it to be the maximum blood pressure value. CONSTITUTION:When a maximum value PwM(n-1) of a pulse wave Pw3(i) is detected, a threshold Thbeta is executed from the PwM(n-1), and a point tU(n-1) to be crossed in the rising part of a Pw(i) and a point tD(n-1) to be crossed in the falling part are detected. A time T(n-1) from the tU(n-1) to the tD(n-1) is calculated, and it is stored. The time T(n-1) is a constant to evaluate the sharpness of the positive peak, and it indicates that the peak is sharper as the value is smaller. From Tm(1)-Tm(n-1) calculated so far, a minimum value is detected, and it is made into a TmMIN. A cuff pressure Pc(i) hourly corresponding to the TmMIN is made into a maximum blood pressure value PSYS. The maximum blood pressure value PSYS is displayed on a display 8 along with a minimum blood pressure value PDIA, a rapid exhaust value 5 is opened, and a subject above-elbow part is released from a pressurization. In such a way, the maximum blood pressure value can be correctly measured.

IPC: G06F17/22
Filed: 1986-03-22
Abstract: PURPOSE:To prevent the over-conversion of KANA (Japanese syllabary) into KANJI (chinese characters) by retrieving the KANA character strings emerging frequently out of a KANA character string store means and excluding them out of the KANJI conversion objects as a pre-stage where the KANA/KANJI conversion is performed after the retrieval of a word dictionary. CONSTITUTION:A character string written only in KANA characters and to be segmented is set and then the arrangements of KANA characters are sorted by the KANJI sounds against said character string. In case a KANJI sound plus KANJI sound, a KANJI sound plus KANA and KANA plus sounds excepting KANJI sounds are decided, the pre-processing is carried out with a HIRAGANA (cursive form of Japanese syllabary) character string (>=5 characters). That is, the corresponding KANA character string is extracted with the reference to a KANA character string memory 8. Then the existence of an additional work is checked and a character string to be retrieved by a dictionary is defined by the arrangement of the head and following KANJI sounds and KANA characters in case no additional word is decided. Thus the access frequency is decreased to the dictionary. In other words, both the processing load and processing time are reduced just by excluding a HIRAGANA character string (>=5 characters) out of the object of KANJI conversion.

IPC: G01N21/64
Filed: 1990-03-15
Abstract: PURPOSE:To correct the effect of condition of the surface of an underlying steel plate by projecting exciting light having a specified wavelength on the surface of the steel plate, and simultaneously picking up and analyzing the intensities in the fluorescent wavelength region and the exciting wavelength region of a reflected spectrum. CONSTITUTION:Luminous flux 2 with a specified exciting wavelength is projected on the surface of a continuously running steel plate 6 from a light source 1. The reflected light from the surface of the steel plate 6 is condensed with a condenser lens 3 and guided into a diffraction grating 7 through a slit 4 and a mirror 5. The intensity of the light which is split in the diffraction grating 7 is measured for every wavelength with a primary photodetector 8. The output of the detector 8 is operated in an operator 9, and the amount of applied oil is computed. The wavelength of the exciting light from the light source 1 is set within an appropriate range from the ultraviolet rays to the visible region. The wavelength range detected with the detector 8 is the flurescent wavelength region set by specifying the preset exciting-light-wavelength region and the applied oil on the surface of the steel plate. When the exciting light is set in this wavelength region, higher fluorescence efficiency can be obtained. Consequently, the photodetector receiving the generated flurescence is provided with a high detecting sensitivity.

Title: Card collating system

IPC: B41L47/46
Filed: 1994-03-09
Abstract: PURPOSE:To provide a simple card collating system with high security without using an online card collating system such as CAT. CONSTITUTION:A magnetic card possesor mentions information on a slip 10 by using the magnetic card 1 obtained by providing magnetic insulation information 6 which cannot visually be viewed and which is previously decided and a slip 10 to which magnetic insulation information 6 is copied. Magnetic insulation information which is provided on the magnetic card 1 and which is previously decided is copied and is visually displayed. Then, both information are collated. When individual information which the person himself can know such as the date of birth of the card possessor, for example, is decided as magnetic insulation information 6, a possibility that a third person can know insulation information is considerably small even if he illegally obtains the card. Even if he illegally intends to use the card 1, information similar to insulation information cannot be mentioned on the slip. Thus, both information are collated and whether they are matched or not is recognized. Thus, the illegal use of the card 1 can previously be prevented.
