Title: Method for modification of excess sludge
Inventor: HORIUCHI KOUICHI
IPC: C02F11/12
Filed: 1980-08-20
Abstract: PURPOSE: To improve the dehydratability of sludge without feeding any chemicals by blowing a proper amount of air or oxygen to the excess sludge having increased gellike materials withdrawn from a final sedimentation basin of a water treatment facilaty by an activated sludge method.  
     CONSTITUTION: If air is blown at, for example, 100W400air/l sludge amount for 10W30hr to the excess sludge having increased gellike mateials withdrawn from a final sedimentation basin, the greater part or part of the gellike materials are removed from the excess sludge by the biochemical reaction of the biological community such as germs which are the constituting factors for the excessive sludge and the mechanical effect of the blown gas.

Title: Conductive roller and manufacture thereof
Inventor: ANDO YASUNARI
IPC: G03G15/00
Filed: 1985-05-28
Abstract: PURPOSE:To obtain a roller, excellent in durability and fully displaying the natural characteristic of a foaming layer by disposing a conductive spring member between a core metal and a hard outermost layer by the spring force of the member itself. CONSTITUTION:A conductive spring member 4 is disposed between a core metal 1 and a hard outermost layer 3, whereby it is conductive between the core metal 1 and the hard outermost layer 3, and it is not necessary to fix the conductive spring member 4 to either the core metal 1 or the hard outermost layer 3 by adhesives or the like. That is, the core metal 1 and the hard outermost layer 3 can be connected to each other by the spring force of the conductive spring member 4 itself to be reliably conductive. Accordingly, a soft forming layer 2 itself is not subjected to any conductivity application treatment, and it can be conductive between the core metal and the hard outermost layer easily and reliably. Thus, a designated rigidity is given to the surface layer of a roller by the hard outermost layer 3, and the functions of natural compressive deformation and buffer property are exhibited by the inside soft foaming layer 2 to be excellent in durability.

Filed: 1995-05-15
Abstract: PURPOSE: To provide a fuel injection control device for a spark ignition internal combustion engine of cylinder injection type enabling the reduction of a shock at the time of a fuel cut as well as to give a moderate deceleration sense to a driver at the time of coasting driving. CONSTITUTION: ECU 70 judges whether or not the present mode is in an after injection mode when a driver return an accelerator pedal and a coasting driving is started. Then, if this judgment is yes, the ECU 70 compares a first valve opening time calculated from an intake air quantity and a target air-fuel ratio with a second opening time computed from a throttle aperture angle and an engine rotating speed, and after selecting the shorter time as a valve opening, the ECU 70 drives a fuel injection valve 4 based on the valve opening time. Thereby, even when bypass air is introduced into a combustion room 5 by ABV 27, an amount of fuel injections decreases so that a torque generated by an engine 1 is decreased if the throttle aperture angle θ TH is small.
