Title: Removal of hydrogen sulfide
Inventor: TERASAKI TAJIROU
IPC: B01D53/34
Filed: 1981-04-23
Abstract: PURPOSE: To prevent the generation of sulfur scale and to attain to enhance a desulfurising ratio by contacting an aqueous solution containing a mixture of an iron chelate compound and a nonionic surfactant with a hydrogen sulfide containing gas.  
     CONSTITUTION: In an absorbing tower 2, the hydrogen containing gas 1 from a viscose preparing process or a sewage treating plant is subjected to gas-liquid contact with an aqueoue solution containing a mixture of iron chelate agent as a catalyst such as nitrilotriacetic acid or ethylene-diamine-tetraacetic acid and a nonionic surfactant which is a polyoxyalkylene alkyl ether type compound.

Title: Wedge like phase plate
Inventor: MORIZAKI SUMIKO
IPC: G02B5/30
Filed: 1986-03-20
Abstract: PURPOSE:To obtain a required phase difference while observing the phase difference of transmitted light by forming a wedge like plate by a plane obtained by inclining a double refractive crystal from an optical axis and displacing a light transmitting position in a thickness changing direction. CONSTITUTION:Incident light from an optical fiber 12 is converted to a linearly polarized light by a polarizer 13 and then converted to 9 circularly polarized light by a 1/4 wavelength plate 11. The light senses a refractive index proportional to a voltage impressed via an electrode 15 in its passage through a photoelectric crystal 14 and generates a phase difference so as to form an elliptically polarized light. The elliptically polarized light is converted into a change in light quantity through an analyzer 16. Since the optical phase bias of pi/2 is applied by the 1/4 wavelength plate 11, light is positively and negatively changed with high linearity in accordance with the positive/negative change of the impressed voltage. Thereby, the phase difference can be easily adjusted so as to obtain the phase difference of 1/4 wavelength by displacing the wedge-like phase plate 11 in the thickness changing direction and finely adjusting the thickness of a position where light is transmitted.

Abstract: PURPOSE:To effectively access to a DRAM provided with various storage areas such as PCM waveform data, control programs, etc., of an SCPU. CONSTITUTION:A PCM circuit 23 generating a musical sound such as a musical sound signal and an effect sound signal, etc., of a BGM accesses to the DRAM 13 frequently since it generates a sound signal based on the PCM waveform data.
