Title: Incineration ash treatment method
Inventor: IMAMURA TOSHIHIDE
IPC: B09B3/00
Filed: 1995-03-24
Abstract: PURPOSE: To implement stabilization treatment to the inside of smoke dust particles of incineration ash etc., and to stabilize the effect for preventing harmful metal elution by kneading a mixture in which incineration fly ash is mixed with a heavy metal stabilizing agent and a surfactant. CONSTITUTION: In treating incineration ash and smoke dust of city waste etc., containing harmful heavy metals, a mixture is kneaded in which incineration ash etc., containing harmful heavy metals are mixed with a heavy metal stabilizing agent and a surfactant. In this process, the heavy metal stabilizing agent and a coagulant can be added. Heavy metals in incineration ash etc., containing harmful heavy metals are stabilized by the heavy metal stabilizing agent to decrease the solubility. When the surfactant is added into this, hydrophobic treatment reaches the pore inner wall of fly ash to hinder the elution of heavy metals from the pore inner wall. When the coagulant is added to the fly ash in which heavy metals are stabilized by the heavy metal stabilizing agent, the stabilized heavy metals are coagulated to further decrease the elution concentration.

Abstract: PROBLEM TO BE SOLVED: To provide the subject method and system therefor, enabling feedstocks to be treated efficiently in a short time and separated into a gas component and solid component in a stable condition. SOLUTION: This method for dry distillation-type cracking which is intended for thermally cracking a feedstock R comprising petroleum-based compounds in a substantially closed space to separate it into a solid component and a gas component, has a conveyance process for conveying a feedstock charged in the front step A of the above closed space toward the rear step B and a heating process for heating the above closed space to thermally crack the feedstock during conveyance operation; wherein the heating process has a temperature-raising stage for heating the feedstock at the front step of the closed space to such a temperature as to enable it to be cracked and a separation stage for thermal insulation at such a temperature as to enable the gas component to be separated until the gas component is nearly entirely separated from the solid component at the rear step of the closed space;  in this case, the temperature-raising stage is designed to set heating energy per unit time to be greater than that in the separation stage.

Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To detect the surface flaw in the lateral direction of a sheetlike article by a simple structure with high accuracy by integrating the feedback signal controlling an AGC circuit changing the mu-factor of a detection signal. SOLUTION: In a beam irradiation means 3, the beam from a laser 10 passes through a focusing optical system 11 and a polygon mirror 12 to scan the surface of an object to be inspected in the lateral direction thereof. The photodetector 21 of a light detection means 4 sends a detection signal to an inspection means 5. The inspection means 5 detects the surface flaw of the object 2 to be inspected on the basis of the output signal of the light detection means 4. In the inspection means 5, an AGC circuit changes a mu-factor so as to make the output signal level of an amplifier amplifying the detection signal constant and the feedback signal controlling the mu-factor of the AGC circuit is integerated by an integration circuit.  By integrating the AGC feedback signal at every scanning as mentioned above, the signal/noise ratio in the detection of the flaw small in density difference spreading over the object 2 to be inspected 2 in the lateral direction thereof can be enhanced.

Title: Photoreceptor element
Inventor: TANAKA YASUO
IPC: H01L31/0248
Filed: 1991-03-29
Abstract: PURPOSE:To obtain a photoreceptor element which is reduced in the amount of after images by making an optical pulse incident to the element while a-10V bias voltage is applied across transparent electrodes and suppressing the amount of after images to <=1% 50ms after the optical pulse is cut off. CONSTITUTION:Transparent In2O-SnO2 electrodes are deposited on a photoconductive film to a film thickness of 1,000Angstrom  by a sputtering method. After the transparent electrodes are formed, an amorphous solid-state image pickup element is obtained. The optical response of the element becomes such that the amount of after images becomes >=10% and the printing of pictures also becomes larger. When the element is heat-treated in the air for 20 minutes at 240 deg.C, an amorphous solid-state image pickup element which is reduced in the amount of after images to 1% and free from printing of pictures is obtained. In other words, the deterioration of the optical responsiveness of the amorphous solid-state image pickup element can be improved when the transparent electrodes are deposited on the photoconductive film by a sputtering method.

When the detecting address and the program address of the counter 23 are coincident, the signal is not sent from the comparator 24 and the rotation of the motor 11 is stopped. Next, when a reproducing switch is operated, the motor 11 executes the low speed normal feeding rotation, both addresses of the counter 23 and the memory 39 are coincident by the comparator 24, then, the rotation of the motor 11 is stopped by the output of the comparator 24.
