Title: Image forming device
Inventor: HANEDA SATORU
IPC: G03G21/00
Filed: 1999-06-09
Abstract: PROBLEM TO BE SOLVED: To prevent disturbance of a toner image by making an electric field generated between fixing members at the time of image formation on a single side opposite to an electric field generated between the fixing members at the time of image formation on both surfaces. SOLUTION: An AC voltage on which a DC voltage having a polarity (positive polarity) opposite to the polarity of toner being used is overlapped is applied by a paper separation AC discharger 14h to recording paper P subjected to image formation on both sides and the recording paper P is consequently separated from an intermediate transfer belt 14a and is carried to a fixing device 17. Toner and the recording paper P are positively electrified on the drive roller 14d. Also, recording paper P subjected to image formation on its surface (one side) is separated by the paper separation AC discharger 14h from the intermediate transfer belt 14a to which an AC voltage on which a DC voltage having a polarity (negative polarity) identical to the polarity of toner being used is overlapped is applied, and the recording paper P is carried to the fixing device 17.  In this case, the recording paper P is negatively electrified on the drive roller 14d.

Title: Air-fuel ratio control system for engine and method of the same
Inventor: NAKAGAWA SHINJI
IPC: F02D41/14
Filed: 1999-06-10
Abstract: PROBLEM TO BE SOLVED: To enable prompt reduction of emission by controlling an air-fuel ratio upstream of a catalyst within a predetermined purification range after correcting it excessively richer than the predetermined purification range when an output of air-fuel ratio detection means located downstream of the catalyst deviates from a predetermined range and becomes lean. SOLUTION: When an engine is operated and an air-fuel ratio downstream of a catalyst 11 interposed in an exhaust system becomes leaner than a high efficiency purification range, a control unit 18 controls supply of an air-fuel mixture into the catalyst so as to maximize a reaction speed in the catalyst 11. Namely, a richer gas than a stoichiometric air-fuel ratio is fed into the catalyst to purge O2 captured by ceria, an auxiliary catalyst in the catalyst 11, and a reduction atmosphere is enhanced promptly. Therefore, emission of NOx deteriorated during the lean condition can be corrected promptly. During the correction, when an air-fuel ratio downstream of the catalyst becomes richer than the high efficiency purification range, a leaner gas is fed to make ceria capture O2 and a reduction atmosphere in the catalyst is enhanced promptly.

Title: Mirror surface of frequency selection
Inventor: MAKINO SHIGERU
IPC: H01P1/20
Filed: 1979-12-17
Abstract: PURPOSE:To obtain frequency selection mirror surface different from the direction of reflection by frequencies, by regularly providing grooves in pillar shape on a metallic plate and changing the parameter of the pillars. CONSTITUTION:A frequency selection mirror surface consists of a metallic plate 1a and grooves 1b of prism shape made on the metallic plate. When the length of sides of metallic lattice is taken respectively as (a) and (b), the incident angle of plane  waves is taken as theta0, and the mirror plane is placed so that the incident plane is in  parallel with the side of (b) in length, then the electromagnetic waves lambda2 in wavelength are reflected on the metallic plate 1a according to the incident direction 2 of  waves, independently of the shape of grooves, by suitably selecting the values (a)  and (b). That is, the electromagnetic waves in lambda2 are not entered the grooves, resulting that the grooved metallic plate 1a is equivalently regarded as a plane reflection plate to the waves in lambda2. Thus, the degree of freedom can be given to the direction of reflection by changing the slope of the metallic plate, allowing to reflect the  electromagnetic waves in shorter wavelength to be reflected on the shape of grooves.

Abstract: PURPOSE:To uniformly introduce a functional side chain into the inner surfaces of the pores of a base material membrane over the whole thereof by placing the base material membrane in a nitrogen atmosphere in which an oxygen absorbent is present before the membrane is brought into contact with a monomer after the irradiation with radiation. CONSTITUTION:A hollow yarn like membrane composed of material quality such as polyolefin is used as a base material membrane and this base material membrane is irradiated with gamma-rays to uniformly generate a radical.
