Inventor: NAGAI TOSHINARI
IPC: F02D45/00
Filed: 1986-08-27
Abstract: PURPOSE:To get rid of any mislearning as well as to make accurate learning control attainable, by making a controller so as to perform the learning control only at a time when slippage between the mean value of air-fuel ratio compensation values and the specified value is larger than the specified one, in the case of a device installing each air-fuel ratio sensor at both upper and lower streams of a catalytic converter. CONSTITUTION:An air-fuel ratio compensation value is operated by an air-fuel ratio compensation value operational device D according to output of an upstream side sensor A is respective air-fuel ratio sensors A and B installed each at both upper and lower streams of the catalytic converter installed in an exhaust system and an air-fuel ratio feedback control constant by an operational device C. And, slippage between the mean value of the air-fuel ratio compensations valves and the specified value is operated by a slippage operational device E, and the slippage is compared with the specified value by a discriminating device F. Here, when the slippage is larger than the specified quantity, the control constant is set down to the constant value so as to have both rich side and lean side variations of the air-fuel ratio compensation value symmetrized, while a learning compensation value is operated so as to make the mean value of the air-fuel ratio compensation values converge on the specified value at a learning device G. And, an air-fuel ratio is adjusted by an air-fuel ratio adjusting device H according to the air-fuel ratio compensation value and the learning compensation value.

Inventor: ASANO ERIKA
IPC: F16C13/00
Filed: 1992-07-27
Abstract: PURPOSE:To obtain a contact electrifying device capable of restraining electrification noise and uniformly electrifying a body to be electrified. CONSTITUTION:As for the contact electrifying device, an electrifying roller (electrifying member) 2 is made hollow, and at least high resistance layer 2-4 is formed at the abutting part of the roller 2 on a photosensitive drum (body to be electrified) 1, then the volume resistivity of the layer 2-4 is set to be larger than that of an abutting member (low resistance layer) 2-1 being an inner layer. Since the roller 2 is made hollow, the roller 2 becomes light and soft and the electrification noise is restrainted to be small. Even though a pin hole is caused on the photosensitive drum 1, the resistance of the high resistance layer 2-4 being the outermost layer is high, so that the leakage of current between the roller 2 and the pin hole is prevented, and faulty electrification caused by abnormal discharge is prevented, and the photosensitive drum 1 is always uniformly electrified.

Title: Optical position detecting device
Inventor: MURO HIDEO
IPC: H01L31/02
Filed: 1986-08-28
Abstract: PURPOSE:To improve the precision of the optical position detection by forming a high impurity density region of the opposite conductivity type so as to surround the one conductivity type layer which forms a junction layer with the opposite conductivity type of the layered region, and connecting to this high impurity density region another electrode corresponding to the electrode for taking out the photocurrent, thereby reducing the non-linear errors in the photo current output. CONSTITUTION:A required positive voltage is applied to a cathode electrode 14, and the P-N junction of the photo detector surface is inversely biased by this positive voltage. When light is projected onto the photo detector surface, an electron-positive hole pair occurs in the projection point of the light, and the photocurrent due to this flows through a n<+> buried layer 5 from the cathode electrode 14, via a n<+> region 15, and from the side. And from respec tive anode electrodes 12, 13 photocurrents relatively varying according to the projection position of the light are respectively taken out. Accordingly, in the current path for the photocurrent in a semiconductor substrate 1, there is not existing any resistance component due to an n<-> epitaxial layer 3 of a high specific resistance, and in the portion of the n<+> buried layer 5, a current flows from its side via the shortest path. For this, in the photo detector surface, the occurrence of different resistance distributions depending on places is remarkably reduced.
