Title: Pyridoxamine type pyridinophane compound and production thereof
Inventor: KUZUHARA HIROMI
IPC: C07D515/08
Filed: 1985-06-04
Abstract: NEW MATERIAL:A compound expressed by formula I (R<1>-R<3> are H or acetyl). EXAMPLE:(S)-(-)-14-Hydroxy-15-aminomethyl-2, 8-dithia[9](2, 5)pyridinophaneS, S, S', S'-tetraoxide. USE:A synthetic reagent for optically active amino acids. PREPARATION:A compound expressed by formula II, e.g. (S)-(-)-15- aminomethyl-14-hydroxy-2, 8-dithia[9](2, 5)pyridin-ophane, is reacted with an acylating agent, e.g. acetic anhydride/pyridine, to give a novel compound expressed by formula III, which is then treated with an oxidizing agent, e.g. hydrogen peroxide and, as necessary, deacetylated. When the hydrogen peroxide is used, the reaction is carried out in the presence of a mixed solvent of dioxane and water and a catalyst, e.g. sodium tungstate-acetic acid.

Title: Optical switch
Inventor: WATANABE TAKAICHI
IPC: G02F1/1335
Filed: 1979-09-21
Abstract: PURPOSE:To obtain a perfect-operation optical switch that permits nearyl 100%  incident light to pass through liquid crystal, by providing a prism, lens, half-  wavelength plate, glass plate, and anisotropic crystal. CONSTITUTION:Parallel light passed through rod lens 21 is separated through anisotropic crystal 71 into polarized light P parallel to a paper face and perpendicular polarized light and polarized light S is converted by half-wavelength plate 81 into polarized light P, which strikes prism 31. On the other hand, polarized light P, having its optical path bent by anisotropic crystal 71, is incident to prism 31 by way of glass plate 91. Thus, polarized light of light incident to prism 31 all becomes polarized light P. While no voltage is applied to clear electrode 5, the light incident to liquid crystal 4 is totallt reflected. Then, polarized light P having passed through half-wavelength plate 81 and polarized light P having passed through glass plate 91 are both led to multimode optical fiber I3 and almost all incident light from multimode optical fiber I1 is taken out of optical fiber I3. Once a voltage is applied, it is led out of optical fiber I4.

Title: Measurement of resonance frequency
Inventor: JIEEMUZU DEII INGURISHIYU
IPC: G01H13/00
Filed: 1986-05-26
Abstract: PURPOSE:To measure resonance frequency of a resonator at high accuracy and at high speed by giving single frequency burst near resonance frequency to a resonator to be measured and measuring a signal outputted by the resonator to be measured when the energy source is taken off. CONSTITUTION:Frequency of a driving signal from a signal generator 10 is selected basing on resonance frequency that can be expected from design specification of a resonator 30 to be measured. For instance, in a resonator of 4MHz very high in Q, frequency is above 100Hz or below 4MHz. However, in a resonator of low Q, frequency is above several thousands Hz or below 4MHz. A switch 20 is closed first, and several cycle is supplied to the resonator 30 to charge the resonator. When desired cycle is supplied to the resonator 30, the switch 20 is opened by control of a cycle counter 50. At this time, the resonator 30 starts oscillation, that is, exponential ring-down. As the resonator consumes previously accumulated energy, the cycle counter 50 counts oscilation cycle, and measures resonance frequency.

Filed: 1989-05-16
Abstract: PURPOSE:To determine an appropriate threshold by generating plural kinds of multilevel patterns based on the plural different set values, and determining the threshold based on the feature quantity related to the arrangement of a picture element to constitute the multilevel pattern. CONSTITUTION:A binary pattern trial-generating part 4 generates and outputs binary picture patterns based on the plural different set values for an inputted signal pattern 2.

Abstract: PURPOSE:To selectively sense the ethanol in a soln. and to measure the concn. thereof by providing the cell membrane fraction of acetic acid bacteria as an immobilized film on an O2 electrode. CONSTITUTION:The sensor formed by mounting the immobilized film 2 of the cell membrane fraction of the acetic acid bacteria to the O2 electrode 1, enclosing the same further with a gas permeable membrane 3 and fixing the same with an O-ring is connected to a recorder 4. The electrode 1 is then inserted into a thermostatic vessel 5 and the inside of the vessel 5 is filled with water, etc. The water is stirred by a magnetic stirrer 6, etc. The output of the electrode 1 stabilizes as well when the dissolved oxygen of the liquid in the vessel 5 attains a specified state. The output current value of the electrode 1 in this stage is measured. The output current decreases when an ethanol soln. of a known concn. is added to the vessel 5. The current value when the output current attains the specified state is measured and the current decrease value is measured. The calibration curve indicating the relation between the ethanol concn. and the current decrease value is formed by repeating the similar operation. The current decrease value is thereafter determined by using a sample soln. of a known concn. and the concn. corresponding to the value obtd. is read from the previously formed calibration curve. The concn. of the sample liquid is thus known.

Abstract: PURPOSE: To perform complete combustion of fuel and generate stable flame by providing a weir within an air passage and opening an air blowing hole toward a draft tube at a part near the housing wall opposite to the fuel injecting direction.  
     CONSTITUTION: In the gun type burner, an annular air passage (a) is defined between the outer wall surface of a draft tube 7 and the inner wall surface of a fuel injecting chamber 2b. In order to close the air passage (a), there is provided the weir 17. Another air passage (b) is provided between a cover member 4 and the draft tube 7. Thus the air stream blown through a duct 2c into the annular air passage (a) is stopped by the weir 17 so that the dynamic pressure of the air is converted into static pressure. The air thus stopped enters into the air passage (b) and flows into the tube 7 making a strong whirling flow therein. This results in a stable and complete combustion of fuel.
