Title: Method for quantifying pitch in manufacturing process of pulp or paper
Inventor: OTANI YASUTO
IPC: G01N21/35
Filed: 1990-02-16
Abstract: PURPOSE:To measure the quantity of pitch in a raw material and a process by performing colorimetry for the pitch in the manufacturing process by using one or more specified wavelengths within a specified range. CONSTITUTION:Light in the region of near infrared rays in the range of wavelengths 0.8 - 2.6 mu gives absorption spectrums peculiar to compounds. The light can be used for the identification and determination of a compound. The spectrums have overlapped absorption bands. Differentiated spectrums are used for processing the bands. Thus, gentle change due to the difference in surface properties, the difference in colors and the like can be erased from the complicated spectrums. The absorption peculiar to the component of pitch can be extracted. Each peak is proportional to the quantity of the component, and the quantity can be determined accurately. The absorption peculiar to the component of the pitch among the near infrared rays is indicated. The light having the wavelength whose quantity can be determined is selected. The correlation with respect to the absorbances of the spectrums and the peak intensities of the differentiated spectrums and the quantity of the pitch is obtained for one or more lights. This expression of the correlation is used, and the quantity of the pitch is determined based on the intensity of the peak.

Title: Protective bellows
Inventor: REMI BOWAYAN
IPC: B29K23/00
Filed: 1995-02-22
Abstract: PURPOSE: To provide a protective bellows of EPDM-polypropylene useful as a protective bellows for an automotive steering mechanism or the like. CONSTITUTION: This bellows comprises a fixing collar 12 for gripping the outside of a casing 18 of a steering mechanism, and a fixing collar 14 for gripping a surface 20 to be mounted with a steering rod 16. The bellows is manufactured of EDPM-polypropylene or similar thermoplastic material in a blow molding method. Compared to conventionally used material, it has a smaller elasticity, so an initial diameter of the fixing collar 14 is decided based on a ratio of a diameter of a boss 22 to the mounting surface 20 so that pressurizing force of the fixing collar 14 to grip the mounting surface 20 provides sufficient gas tightness initially and during an expected durable period of the bellows.

Title: Robot copying controller
Inventor: YABUKI AKIHIKO
IPC: G05B19/4093
Filed: 1990-02-16
Abstract: PURPOSE:To automatically set a work coordinate system in an on-line method in order to smoothly copy the surface of a work subject having an unknown shape by providing a press control means. CONSTITUTION:A press control means 19A controls the press of the robot fingers to a work subject at the start point of the copying work. A tentative target vector having the value ¦Forl¦t is commanded from the start point in the direction where the work subject exists, and the press control is performed in a state where the freedom degree of translation is stricted to '1' at the tip of a probe. This press operation ends when the component of the contact force Far detected by a force sensor is equal to ¦Forl¦t in the tentative target vector direction. IN this case, a subscript (t) shows the value of the translation vector. As a result, a work coordinate system is automatically set in an on-line method and the surface of a work subject having an unknown shape is smoothly copied.

Abstract: PURPOSE:To assure stability of continuous use and enhance photoelectric conversion efficiency by covering an organic solar cell with a protective layer for shielding a short wavelength light having a wavelength of specific value or less. CONSTITUTION:A thin organic photoconductive dispersive film 3 is sandwiched with a light transmissible electrode 2 from its upper side and with a counter electrode 4 from its lower side, and the electrode 4 is supported by a substrate 5.

The electrode 2 is covered with a protective layer 1 from its outside. The layer 1 must shield a short wavelength light having a wavelength of 450nm or less. The short wavelength light is shielded, thereby preventing a charge transport substance from absorbing the short wavelength light. When the absorption end of the layer 1 is lambda1 (nm) and the absorption end of the substance is lambda0 (nm), lambda0<=lambda1<=lambda0+50 is preferably satisfied.

Title: Printing sheet for preventing falsification
Inventor: UKO KEIICHI
IPC: B42D15/10
Filed: 1993-01-29
Abstract: PURPOSE:To provide a printing sheet in which the presence of falsification of information printed with toner can be discriminated visually and easily. CONSTITUTION:An undercoat layer 3 is placed on the surface of a sheet base material 2 by printing toner over the surface using a nonimpact printer, and character information 4 is printed on the undercoat layer 3 with a different kind of toner using the same nonimpact printer to make a printed sheet 1. Since the character information 4 and the undercoat layer 3 are printed with toner, they are bonded firmly to make it difficult to strip off the character information 4 from the undercoat layer 3. If the information is stripped off forcedly from the undercoat layer 3, the undercoat layer is also stripped off together with the information. The part of the sheet, from which the undercoat 3 is stripped off, appears different such as in color which is thinned as compared with other parts, thereby indicating falsification.

Title: Corona discharge detector in power installation
Inventor: SUENAGA KIYOYOSHI
IPC: H02H3/14
Filed: 1996-02-22
Abstract: PROBLEM TO BE SOLVED: To make it possible to analyze corona discharge without a stoppage in power, by detecting a position of noise generation and its conditions in corona discharge on the basis of a containing rate of a frequency factor that is twice the power supply frequency in strong and weak factors. SOLUTION: A direction of sound in discharge is discriminated by an acoustic direction detecting unit 10. An acoustic detecting unit 1 is turned to the direction of sound to receive the sound in discharge. The sound is amplified in a first stage amplifier 2, passed through a high-frequency passing filter 3 to remove noises, and amplified again in a second stage amplifier 4. After the sound signal without noises is rectified by a rectifier 5, the sound signal is subjected to envelope detection, and an analog signal as strong and weak factors of the sound is converted into a digital signal by an A/D converter 7. The digital signal is fed to a CPU 8, and fast Fourier transform is carried out to obtain a stable waveform with frequency twice the power-supply frequency.  As a result, the generating position of corona discharge can be judged from the acoustic signal and the conditions can be detected, and the analysis can be carried out without a failure in power.
