Title: Reduction combustion method and composition used for said method
Inventor: JIYON EI SHIRIATSUKUSU
IPC: C02F11/00
Filed: 1987-05-01
Abstract: Process for reduction of anionic components of chemicals, and compositions for use in the reduction process. Chemicals to be reduced are typically of the oxysulfur or sulfurnitrogen families. The reduction is carried out with mixing of carbonaceous fuel with the chemicals to be reduced. Reduction takes place in a reduction furnace having a char bed. Mixing in of the carbonaceous fuel may take place before introduction into the furnace, or may take place in the furnace itself. High levels, over 75%, of conversion are achieved in reducing sulfate to sulfide.

Title: Transferred paper peeling device for electronic copying machine
Inventor: MOMOTAKE NOBUO
IPC: G03G15/14
Filed: 1981-07-14
Abstract: PURPOSE:To peel surely a transferred paper without disturbing the toner image on the transferred paper, by bringing a conductive brush, to which a bias voltage is applied, to the transferred paper, which is brought closely into contact with a photoreceptor, to discharge the transferred paper. CONSTITUTION:The toner image, which is developed by a developing device, on the surface of a photoreceptor 1 is discharged by a discharger 2 and reaches a transfer equipment 3 and is transferred to a supplied transfer paper 4. The transferred paper 4 to which the toner image is transferred is brought closely into contact with the photoreceptor 1 and reaches a conductive brush 5. An AC bias voltage is applied to the brush from a power source 6, and tips of many conductive brush hairs 5b stood on the surface of a columnar core 5a are  brought into contact with the transferred paper 4, which is brought closely into  contact with the photoreceptor 1, while rotating in the direction of an arrow to  discharge the transferred paper 4. Consequently, the attractive force of the transferred paper 4 is weakened, and the transfer paper 4 is peeled from the photoreceptor 1 by its solidity and weight. Thus, the transferred paper is peeled surely without disturbing the toner image on the transferred paper.

Title: Controller for diesel engine
Inventor: AOKI ATSUSHI
IPC: F02D41/04
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To control an excess air ratio so that it is not made smaller than a target value through calculation of the excess air ratio by variably controlling concentration and amount of oxygen of intake air, changing the amount of oxygen without varying the oxygen concentration in the intake air according to operating conditions of an engine to control the excess air ratio above the target value. SOLUTION: An excess air ratio is calculated from the amount of intake air detected by an air flow meter 12, the concentration of residual oxygen within exhaust gas detected by an oxygen concentration sensor 13, and the amount of fuel injection. The calculated excess air ratio is compared with the prescribed value. When the excess air ratio is smaller than the prescribed value, an EGR rate is calculated based on the information given from the sensors and stored. EGR rate is recalculated and compared with the stored EGR rate. If the EGR rate, which was once reduced due to a rise in boost pressure, is not increased to a level equivalent to the stored EGR rate, an EGR valve 5 is opened and an operation to increase the EGR rate is repeated. Consequently, NOx and PM are reduced simultaneously, and fuel economy is maintained satisfactorily.
