Title: Feedback control method for air-fuel ratio of internal combustion engine
Inventor: AKIYAMA EITETSU
IPC: F02D41/00
Filed: 1987-02-02
Abstract: PURPOSE:To compensate aged deterioration, by successively detecting an integration value to a point of time, in which an exhaust concentration detection value changes from a lean side to a rich side, and an integration value to a point of time in which the exhaust concentration detection value changes from the rich side to the lean side, in the case of an air-fuel ratio feedback control. CONSTITUTION:An electronic control unit 5, which calculates the basic fuel injection quantity on the basis of detection values from an intake absolute pressure sensor 8 and an engine speed sensor 10, compares a detection value of an O2 sensor 13 with the reference value performing a feedback control of air-fuel ratio by a proportional plus integral control. The electronic control unit 5 successively measures a point of time t1, in which the detection value of the O2 sensor 13 changes from a lean side to a rich side with respect to the reference value, and a point of time t2 in which the detection value of the O2 sensor 13 changes from the rich side to the lean side with respect to the reference value. And detecting the displacement of the air-fuel ratio on the basis of ratio of an integration amount between the points of time t1-t2 to the integration amount between the points of time t2-t1, the electronic control unit 5 changes a proportional constant and an integration constant in a direction of small decreasing this displacement.

Title: Power source device of electric precipitator
Inventor: ISHII YASUHIRO
IPC: B03C3/66
Filed: 1985-02-07
Abstract: PURPOSE:To improve charge efficiency with low cost by feeding charge to two electric precipitator from one power source device by using a tapped boosting transformer 13 through a thyristor 2. CONSTITUTION:When a source voltage VS fed from a source terminal 1 is inputted to a primary side of a tapped boosting transformer 13, a high voltage 2VT is generated in the secondary side of transformer 13, and EP6-1 and EP6-2 are charged alternately by a half-wave. Namely, when VS>=0, current passes through a loop L1 and EP6-1 is charged. The current through a loop L2 is inhibited by a rectifier 14-2, so EP6-2 is not charged. Oppositely, when VS<=0, EO6-2 is charged and EP6-1 is not charged. Accordingly, two EPs can be charged by one power source device. Therefore, cost reduction is realized, and operation is performed with good efficiency resulting in saving of energy consumption.

Filed: 1979-02-27
Abstract: PURPOSE:To improve the output of the radio wave for response and stability of the frequency by providing a resonator, which resonates within the sweep range, in a responser to utilize ringing generated by receiving demodulation. CONSTITUTION:The radio wave transmitted from antenna 2 of interrogator 101 is changed within a periodical frequency range by frenquency sweep circuit 8, and is modulated by the output of modulation wave oscillator 7 whose period is determined by timing circuit 9. Antenna 11 of responser 102 receives this radio wave and converts it to a DC by rectifier circuit 15 and supplies required power to respective parts. Simultaneously, antenna 11 demodulates the modulation wave in 18 to detect the sweep period and sets the sweep period to clocks of sequence unit 13 through timing detection circuit 19. Meanwhile, the output of circuit 18 is applied to resonator 20 which resonates at a specific point within a variable frequency range, and ringing phenomena are generated by this peculiar frequency. Modulation 15 of a short time width dependent upon periodical ringing is applied to the receiving wave radiated again. In the interrogator, a code string where presence and absence of ringing modulation are binary is detected through receiving detector 4, ringing detector 10 and demodulator 5.

Title: Packing ring for radial shaft
Inventor: HERUMUUTO HERUTSUAA
IPC: F16J15/3224
Filed: 1983-02-14
Abstract: A radial shaft seal ring has a lip ring for sealing to a shaft for rotation therewith. A U-shaped recess extends around the lip ring. An extension portion of a reinforcing ring which delimits a space on one side thereof to be sealed contacts the U-shaped recess without pressure or connection for low wear relative rotation therein. Preferably, the shoulder of the lip ring defining the side of the U-shaped recess on the sealed-space side of the reinforcing ring has a greater outside diameter than that on the other side to centrifugally aid the seal. More preferably, the latter is done by angling the U-shaped channel to the sealed side to also accommodate axial vibration of the shaft and lip ring.

Abstract: PURPOSE:To eliminate fogging at a non-image part and to improve brush resistance and eliminate the need for water to wet by forming the no-image part on an organic photoconductor layer by using a developer consisting principally of a (meth)acrylate polymer or copolymer which contains fluorine atoms. CONSTITUTION:A lithographic plate 1 consists of a conductive substrate 2, an organic photoconductor layer 3, an image part 4, and the no-image part 5.

An original plate provided with the organic photoconductor 3 on the conductive substrate 2 is corona-discharged in darkness, image exposure is carried out by scanning semiconductor laser light, etc., and toner development and heat fixation are performed. Consequently, no developer sticks on the exposed part to form an image part 4 and the developer sticks on the unexposed part to form the no- image part 5. Thus, ink sticks on the organic photoconductor layer without any wetting water and does not stick on the no-image part at all to obtain a print of high quality.
