IPC: B05D5/00
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To make it difficult to stain the substrate surface of a structure body of a railway car and make it easy to clean the surface by forming a top coat layer which comprises a photo-semiconductive layer and of which the surface is made to have a specified value of water wettability corresponding to photo-excitation by irradiation with light rays with the wavelength to excite photo-semiconductive oxides or shorter. SOLUTION: A layer containing a photo-semiconductive layer is formed on a substrate surface of a railway car either directly or through a base coat layer and a top coat layer of which the surface is made to have wettability to water 10-degrees or lower based on the contact angle to water responding to photo-excitation by light irradiation is further formed.  At that time, the level of the lower end of the conduction band energy of the photo-semiconductor is made to be a positive value in the case the hydrogen production level is set to be 0eV or a substance to inhibit the photolytic redox reaction of the photo-semiconductor is added to the photosemiconductive layer, so that the photo-semiconductive layer is changed to be hydrophilic responding to photo-excitation by irradiation with light rays having wavelength to excite the photo semiconductor or shorter at 1mW/cm<2> illuminance or lower. One or more substances selected from alkali metals are used as the substance to inhibit the photolytic redox reaction.

Title: Step motor driving method
Inventor: TAMAOKI SHUNPEI
IPC: H02P8/22
Filed: 1990-05-29
Abstract: PURPOSE:To maintain the displacement of load approximately constant even in the case of 1-2 phase excitation by setting the conduction current control level, in an exciting step where the number of motor coil to be conducted is high, lower than that in an exciting step where the number of motor coil to be conducted is low. CONSTITUTION:A driver control section 1 perform constant current control based on two conduction current control values, i.e. control currents, I1, I2 for one-phase excitation and two-phase excitation in 1-2 phase excitation driving. When switching is made such that the conduction current control value (control current I2) in an excitation step (two-phase excitation) where the number of motor coil to be conducted is high is smaller than the conduction current control value (control current I1) in an excitation step (one-phase excitation) where the number of motor coils to be conducted is low, outputtorque of motor in one-phase excitation and two-phase excitation are approximately equalized thus suppressing fluctuation of feeding amount (displacement) of motor with respect to a load in 1-2 phase excitation driving.

Title: Purification of acetic acid
Inventor: YASUDA KIYOSHI
IPC: C07C67/00
Filed: 1978-11-06
Abstract: PURPOSE: To improve the quality of acetic acid economically, in an industrial scale, with single procedure, by treating a crude acetic acid with an ozone-containing gas.  
     CONSTITUTION: A high quality acetic acid having long color retention time by KMnO 4  test and low ApHA value by H 2 SO 4  test, is prepared by introducing an ozone-containing gas into acetic acid to be purified. The process can be applied to any acetic acid produced by industrial processes, however, it is not desirable to apply to a crude acetic acid containing too much impurities, because it consumes a large amount of the ozone-containing gas. It is most preferably applied to acetic acid having a purity of ≥99%, e.g. prepared by distilling the above crude acetic acid. The ozone-containing gas is prepared by ozonizing air or oxygen with a commercial ozonizer. Since the purification process of this invention can be carried out at room temperature under atmospheric pressure without using a distillation process, the heat energy is saved. As the post-treatment of the product is not necessary, there is no trouble of environmental pollution or safety. The process can be easily made continuous and automatic.

Title: Three-phase system photocurrent sensor
Inventor: KATSUKAWA HIROYUKI
IPC: G01R29/16
Filed: 1988-06-03
Abstract: PURPOSE:To make it possible to detect a zero-phase current highly accurately by attaching insulators with sensors each having a Faraday element and a magnetic field adjusting mechanism to three-phase conductors, and connecting the Faraday elements with optical fibers in series. CONSTITUTION:Each insulator 2 with a sensor houses optical fibers 3 in an insulator main body 4. Three conductors 1 in three-phase lines are clamped with conductor clamps 5. A Faraday element 6 which is attached in the clamp 5 detects a magnetic field which is generated with the current through the conductor 1 with a photocurrent. An optical signal is sent through optical fibers 3 from a light emitting element 12 in a converter 10. The optical signal is made to pass three elements 6 sequentially. Then, the optical signals caused by the currents in three phases are synthesized. The optical signal corresponding to the zero-phase current is taken out of a photodetector 13. Even if there is dispersion in sensitivities of the elements 6, each element housing part 8 is moved back and forth in a screw hole 7 with a magnetic field adjusting mechanism 9. Thus, the intensity of the magnetic field passing through each element 6 is adjusted. Therefore, the slight fluctuation of the zero-phase current value can be positively detected.
