Title: Manufacture of bonded veneer
Inventor: YAMADA TSUKASA
IPC: B27D5/00
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To prevent a bonded part from being rough on the surface after coating by applying a coating containing at most, a specified value wt.% of a moisture-setting urethane adhesive having resistance to a butyl acetate solvent and this solvent for the total amount of the coating. SOLUTION: Flitches 1 are bonded using a moisture-setting urethane adhesive 2 with resistance to a butyl acetate solvent. After bonding the bonded flitches 1 to a base board after slicing, a coating containing 5 wt.% of a butyl acetate solvent for the total amount of the coating is applied. Thus synergic effects between the moisture-setting urethane adhesive 2 with resistance to the butyl acetate solvent and the coating containing at most, 5 wt.% of the butyl acetate solvent for the total amount of the coating is generated. Consequently, a chemical reaction between the butyl acetate solvent contained in the coating and the moisture-setting urethane adhesive 2 sticking to the bonded part between the veneer-like flitches 1, is prevented from occurring and also the expansion of these chemicals does not take place.

Title: Sludge thickening device
Inventor: KITAO TAKANE
IPC: C02F11/12
Filed: 1991-12-11
Abstract: PURPOSE:To facilitate the maintenance and control by separating sludge to clean supernatant having a low suspended matter concn. and sufficiently thickened sludge. CONSTITUTION:A thickening vessel 1 is formed with a settling section 2 in the lower part and formed with a supernatant section 6 in the upper part. A filter medium packed bed 7 consisting of many contact filter media is provided in the lower part from the water surface of the supernatant section 6. An aeration section 8 is opened by vertically penetrating the filter medium packed bed 7 and is inserted with an air diffuser 9 in the lower part is formed. An air back washing device 12 is installed to face the lower part of this filter medium packed bed 7. As a result, the heavy sludge of the sludge which is to be treated and supplied to the thickening vessel is thickened by settling in the settling section. The suspended sludge floating on the supernatant layer is captured in the filter medium packed bed by the circulating flow formed by the ascending current generated in the aeration section, by which the clean supernatant water is separated. The sludge to be treated is thus rapidly separated to the thickened sludge and the supernatant liquid of the low suspended matter concn. The filter medium packed bed is easily regenerated by the air back washing device when the filter medium packed bed is clogged by the sludge captured therein. The maintenance and control are thus facilitated.

Title: Substrate processing device
Inventor: NAKAGAWA YOSHIYUKI
IPC: H01L21/304
Filed: 1996-11-22
Abstract: PROBLEM TO BE SOLVED: To quickly equalize the concentration of processing liquid to a target value by a method wherein the control input of an inert gas control means is determined directly proportional to the deviation of a detected value, the control input of an inert gas control means is determined directly proportional to the integral of deviations so as to control pressure on chemical liquid to forcibly feed it. SOLUTION: A flow-rate sensor 5 detects the flow rate of chemical liquid which is forcibly fed to a chemical liquid inlet valve 9a. A flow-rate feedback controller 6 receives detection signals outputted from the flow rate sensor 5 and outputs pressure correction signals for controlling a pressure feedback controller 7. The flow rate feedback controller 6 and the pressure feedback controller 7 determined the control inputs of control objects based on a deviation obtained by subtracting a target value from an observed value. A voltage applied to an electropneumatic regulator 23 is determined directly proportional to the deviation of the detected value of the flow rate sensor 5, and the voltage applied to the electropneumatic regulator 23 is determined directly proportional to the integral of the deviations of the detected value.  By this setup, the concentration of processing liquid can be quickly equalized to a target value.
