Title: Hydraulic machine provided with electrically operated servo-motor
Inventor: KUWABARA HISAO
IPC: F03B15/18
Filed: 1982-05-24
Abstract: PURPOSE:To aim at enhancing the safety of a hydraulic machine, by controlling the closing operation of guide vanes, upon the running speed of the hydraulic machine being abnormally increased, with the use of a flow regulating valve for a damper. CONSTITUTION:When an emergency closing instruction signal is generated by the operation of a protecting circuit due to abnormal increase in the running speed of a hydraulic machine, a clutch 7 is at first disengaged so that restraint force is released. A solenoid valve 11 in a bypass line 12 for a damper 8 is automatically closed at the step of deenergization of a control power source, and therefore, the damper 8 is in the condition of ''alive''. Accordingly, guide vanes initiate their closing operation by being subjected to hydraulic pressure in the closing direction under the stable condition when the clutch 7 is disengaged, and the closing speed of the guide vanes is controlled by a flow regulating valve for the damper 8, thereby the safety of the hydraulic machine may be enhanced.

IPC: G01J1/00
Filed: 1982-05-21
Abstract: PURPOSE:To permit to attain photoelectric output by obtaining luminous intensity on the surface of photoelectric converter and an exposure amount conversion factor. CONSTITUTION:Radiation from a reference light source 1 is separated into its spectral components by a monochromator 2 for each unit wave length and then converted to an electrical signal by a tested photoelectric converter 3. This photoelectric output for each unit wave length is transmitted to a tested photoelectric converter spectral sensitivity storing section 10. A measuring light amount arithmetic section 4 receives the data from a tested light source spectral radiation intensity storing section 7 and a reference light source spectral radiation intensity storing section 8 to multiply those data together for each unit time. Similarly, a radiation amount arithmetic section 5 multiplies the data from the storing sections 7, 8 and 10 together for each wave length. Next, outputs from the arithmetic sections 4, 5 are sent to an exposure amount conversion factor arithmetic section 6, where the ratio of outputs from both arithmetic section 5 and 4 are calculated to obtain an exposure amount conversion factor.

Abstract: PURPOSE:To obtain a (di)chromate ion adsorbent excellent in strength and expansion-contraction resistance, by a method wherein a fine powdery solid substance carrying a polymerization initiator is adsorbed by the vapor of vinyl pyridine and a crosslinkable vinyl monomer to directly carry out polymerization. CONSTITUTION:A polymerization initiator such as azo-bis-isobutylonitrile is preliminarily carried by a fine powdery solid substance such as zeolite. Vinyl pyridine such as 4-vinyl pyridine and a crosslinkable divinyl monomer such as divinyl benzene are brought into contact with the surface of said solid substance in a vapor state and these monomers are homogenously adsorbed by the surface of the solid substance. In the next step, these monomers are subjected to polymerization reaction in the absence of a solvent under an inert gas atmosphere to form a strong resin film on the surface of the solid substance particle. The adsorbent obtained by this method is excellent in mechanical strength, expansion-contraction resistance and durability, high in the adsorbing speed of a (di)chromate ion and easy in regeneration.

Title: Plasma apparatus
Inventor: ARAKI YOICHI
IPC: H05H1/46
Filed: 1992-04-08
Abstract: PURPOSE:To prevent sputtering to a material to be processed by drawing electrons from a plasma of a helicon wave, accelerating it to be guided to a reaction chamber, and generating a plasma of reaction gas by the accelerated electrons to process the material to be processed. CONSTITUTION:When high frequency power is applied to a helicon wave generating antenna 2 to excite a helicon wave in a discharge tube 18, a plasma is efficiently generated, electrons in the plasma are drawn to an accelerating space 3 by electrodes 9, 10, accelerated by the accelerating electrode 10, and guided to a reaction chamber. On the other hand, reaction gas is introduced from a gas inlet tube 14 to the chamber 4, the gas is dissociated by the accelerated electrons to generate an active species, thereby etching a wafer. Thus, since a plasma generating electrode is not used, sputtering of a material to be processed due to ions of a cathode electrode and metal contamination due to vaporization of a material upon rising of a temperature of an anode electrode can be eliminated.

Abstract: PURPOSE: To prevent the rash by ammonia gas by spraying a diluted solution obtained by diluting purified wood vinegar obtained from broadleaf trees with purified water to a diaper, or dipping the diaper therein followed by drying. CONSTITUTION: When a diluted solution with purified water of purified wood vinegar obtained from broadleaf trees is used, a gas adsorptive effect such as ammonia gas is enhanced.

Title: Analog-to-digital conversion method
Inventor: MANABE TSUTOMU
IPC: H03M1/12
Filed: 1985-04-24
Abstract: PURPOSE:To obtain the display data just with the binary-decimal conversion by performing the initial control so as to obtain the 2<n> output when the analog quantity of 2<n> is applied to an n-bit A/D converter and then multiplying 2<n> obtained by multiplying said analog quantity by 1/2<m> and applying it to the A/D converter by 2<m> when the analog quantity 2<n>X2<m> is measured. CONSTITUTION:The initialization is carried out so that the output of '1' is obtained with all (n) bits when the analog quantity of 2<n> is applied to an n-bit A/D converter 2. Then, the analog quantity of (2<n>X2<m>) is multiplied by 1/2<m> when this analog quantity is measured. Thus the output of 1 is obtained with all (n) bits by the converter 2. These outputs are shifted up or down by (m) bits and therefore the binary data of '1' is obtained with all (n+m) bits. The binary-decimal conversion is given to the binary data to obtain the display data corresponding to the original analog quantity. In other words, an analog quantity is obtained just with the binary-decimal conversion and with no use of a conversion table. This reduces the cost and also shorten the data converting time.

Abstract: PURPOSE:To efficiently and simply treat waste water within a short time by a method wherein an additive based on highly active quick lime is added to waste water to be mixed and reacted therewith under stirring and a solid component is separated from the obtained slurry and, after the pH of the slurry is controlled, water treatment is performed. CONSTITUTION:An additive based on highly active quick lime high in the content of calcium oxide (desirably 95% or more), having a porous structure and a wide surface area and specific surface area and highly developed in its pore structure is added to waste water and reacted therewith to separate a solid component. Since the separated solution is made alkaline by the addition of the additive, neutralization is necessary. This pH control is reduced corresponding to the addition ratio of the additive. After pH control, solid-liquid separation employed in a conventional water treatment system and post-treatment used in general are performed. Since a phosphorus compound is effectively treated by this treatment, the load of post-treatment is markedly reduced.
