Title: Method for measuring continuously concentration of caco3 and concentration of caso3 in slurry
Inventor: TATANI ATSUSHI
IPC: G01N31/00
Filed: 1984-01-25
Abstract: PURPOSE:To enable exact continuous measurement of the concns. of CaCO3 and CaSO3 in the absorbent slurry in wet lime method desulfurizer for stack gas for a long period of time in a method for measuring continuously said concns. by mixing sulfuric acid or hydrochloric acid with the air to be used for discharging the gas formed by reaction and blowing the mixture into a reaction vessel. CONSTITUTION:A slurry A contg. CaCO3 and CaSO3 or either thereof is continuously drawn at a specified rate and is supplied to a stirring type continuous reaction vessel 5 isolated from the outdoor air. The air B controlled to a required flow rate by a flow rate controller 11 is mixed with the hydrochroric acid (or sulfuric acid) fed from a micropump 28 driven by the signal of a pH controller 15 controlling the pH of a stagnating liquid 6 via a flow rate indicator 17 and is then blown via an air blow pipe 8 into the stagnating liquid 6 in order to discharge smoothly the CO2 and SO2 generated by adding sulfuric acid or hydrochloric acid C to the vessel and bringing the same into reaction with the CaCO3 and CaSO3 in the slurry. The decrease in the measuring accuracy of the concns. of the CaCO3 and CaSO3 owing to scale formation is thus prevented and the continuous and exact measurement of the concns. over a long period of time is made possible.

Title: Current controller for electric vehicle
Inventor: IKUI SHIYUUICHI
IPC: B60L15/20
Filed: 1979-02-02
Abstract: PURPOSE: To prevent low-frequency oscillation from being caused, by synchronizing the AC power source of a direct current transformer with that of an electric vehicle line in acceleration but with brake control frequency in braking.  
     CONSTITUTION: A current pattern signal 1 corresponding to an accelerating current limit and a feedback signal 2 of a closed circuit control system proportional to an accelerating current are compared with each other by a comparison amplifier 3. The difference between both the signals is amplified and then transmitted to a phase controller 4. A power converter 7 is connected through an electric vehicle line 5 and a transformer 6 and receives the output of the phase controller 4 so that DC power corresponding to the speed of an electric vehicle is supplied to a motor circuit 11. A direct current transformer 13 receives AC power through the electric vehicle line 5, the transformer 6 and a contact P of a changeover circuit 31 in acceleration but receives AC power 14 synchronized with power, which determines brake control frequency, in braking. As a result, both in acceleration and in braking, the AC component of the output of the direct current transformer is synchronized with control power and a current beat phenomenon due to frequency difference is prevented.

Title: Avalanche photodiode
Inventor: TORIKAI TOSHITAKA
IPC: H01L31/107
Filed: 1989-01-18
Abstract: PURPOSE:To enhance sensitivity by making valence band discontinuity amount in the band discontinuous part of an oblique type periodic structure larger than a conduction band discontinuity amount. CONSTITUTION:A semiconductor material in which conduction band discontinuity DELTAEv is increased larger than conduction band discontinuity DELTAEc in an oblique type periodic structure such as InGaAs, GaAsSb/InP is selected. Thus, since large DELTAEv is provided so that hole carrier generated by an incident light is obtained excessively by DELTAEv in the valance electrons discontinuity part, ionization more easily occurs. On the contrary, since electron carrier loses small DELTAEc or by DELTAEc of energy in a conduction band discontinuity part, ionization scarcely occurs. Thus, sensitivity can be enhanced.

Abstract: PURPOSE:To generate water currents suitable for regular cloth circulation state corresponding to the amount of cloths by a method wherein the cloth circulation state is always detected by the counter electromotive force of a motor via a rotary impeller, and the reversional intervals at the next time are controlled according to the number of waveforms or the magnitude of voltage of the counter electromotive force. CONSTITUTION:Measuring of counter electromotive force of a motor is started from points (a) and (b) immediately after the completion of clockwise and counter clockwise revolutions of a rotary impeller to detect the magnitude of the number of waveforms of the counter electromotive force, and a reference cloth circulation waveforms at a certain water level, for example, at a medium water level, is previously set. When the number of waveforms is larger than that of the reference waveforms, the rotational frequency of the agitator impeller is changed by changing the capacity of a motor start-up capacitor to change the torque, and the rotational frequency of the motor itself is reduce by inverter control. Wen the number of waveforms is less than that of the reference waveforms, the rotational frequency is increased by increasing the capacity of the capacitor or by inverter control. Thereby, a stable cloth circulation state with a regular water current can be maintained, resulting in prevention of damages on cloths.

Abstract: PURPOSE:To produce the aluminum foil for electrolytic capacitors with which excellent etching performance and the high electrostatic capacity are obtainable and which is free from the fluctuation in the electrostatic capacity in a transverse direction. CONSTITUTION:An aluminum slab having >=99.9% purity is used and before the slab is subjected to final finish rolling after hot rolling, the aluminum foil base is subjected to at least one pass of washing for removing the surface layers, by which the flaw-like recessed parts and inclusions, such as Al oxides and carbon, on the foil surfaces are removed. As a result, the generation of the coarse etching pits by the unavoidable local concn. of these recessed parts and inclusions is obviated and the uniform etching pits are formed. In addition, the aluminum foil is subjected to a low-temp. heating treatment in an atmosphere of <=0.05kg/kg moisture content prior to final annealing after foil rolling and, therefore, the thickness in the transverse direction of the oxide films formed on the surfaces of the aluminum foil is previously uniformalized and the fluctuation in the electrostatic capacity is prevented prior to final annealing.
