IPC: F23N5/18
Filed: 1991-08-30
Abstract: PURPOSE:To improve the accuracy of controls by a method wherein a gas control valve and an air damper are controlled corresponding to the loads, and it is checked whether the constant controls of the air-fuel ratio is attained based on the output controlled variables. CONSTITUTION:A controller 30 is composed of a gas controller 31 to which a gas pressure sensor 5 is connected, an air controller 32 to which an air pressure sensor 11 is connected, and an air-fuel ratio controller 33. At the gas controller 31, the manipulated variables of a gas control valve 3 corresponding to the loads are calculated based on gas pressure data, and the valve lift of the control valve 3 is regulated. The valve lift of an air damper 8 is controlled in the similar manner. At the air-fuel ratio controller 33, the gas and air controlled variables respectively calculated by the controllers 32 and 32 based on the load and the pressures are compared with each other to check whether they are at the specified air-fuel ratio, and the results are indicated. Therefore, as the accuracy of the feed rates is improved and the air-fuel ratio is easily kept at the specified ratio, the normal combustion is carried out, and as the air-fuel ratio can always be monitored, the fuel consumption is improved.

Title: Lumber drying device
Inventor: YAMAMOTO KOJI
IPC: F26B3/347
Filed: 1993-09-30
Abstract: PURPOSE:To prevent lumber from being warped by a method wherein an abut ting position of an electrode plate against the lumber is detected in order to abut the electrode plate against the lumber and a driving of the electrode plate is controlled based on the results of sensing operation. CONSTITUTION:A high frequency is applied between electrode plates 7 while the electrode plates 7 are being installed on both surfaces of a piece of lumber 4 and the lumber 4 is dried with an induction heating with a high frequency electric field produced between the electrode plates 7. As the drying is carried out, the lumber 4 is shrinked and as the abutting position of the electrode plates 7 is varied, one electrode plate 7 is driven until it abuts against the lumber 4 and then a clearance is prevented from being generated between the electrode plate 7 and the lumber 4. As the drying operation is promoted, strain and stress are produced within the wooden member 4. When the strain and stress are applied to the electrode plates 7, transmission of the strain and stress to the driving motor 14 is prevented by driving force transmitting means (screw jacks) 8 and 9 and the abutted state of the electrode plates 7 against the lumber 4 is kept. With such an arrangement as above, it is possible to prevent warp of the lumber 4.

Title: Polarizing plate and ellipsoid polarizing plate adhesive sheet
Inventor: SAWADA TAKAHIKO
IPC: C09J7/02
Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To suppress the generation of bubbles between an adhesive sheet and a glass cell or a body to be adhered in a high temp. or high temp. and high humidity environment by specifying the variance in the thickness of an acryl adhesive layer formed on the surface to a specified range. SOLUTION: This adhesive sheet with a polarizing plate or a elliptically polarizing plate consists of a polarizing plate and/or phase different compensator and an acryl adhesive layer formed on the surface of the plate. The variance in the thickness of the acryl adhesive layer in the plane is specified to <=0.05 standard deviation. When the variance in the thickness of the adhesive layer between the polarizing plate and elliptically polarizing plate is controlled to <=0.05 standard deviation, the adhesive coating film is uniformly dried and uniformly crosslinked on the coating plane, thereby, no residual stress produced when the sheet is adhered to a glass cell or other bodies generated by irregular thickness of the layer can be prevented.  Thus, the polarizing plate or elliptically polarizing plate can maintain stable optical performances even in a high temp. or a high temp. and high humidity environment.
