Title: Exhaust constituent measuring instrument and engine air/fuel ratio control system
Inventor: UENO SADAYASU
IPC: G01N27/419
Filed: 1997-04-22
Abstract: PROBLEM TO BE SOLVED: To expand the controllability of the air/fuel ratio of, for example, an engine to a high-speed region by performing the bi-directional negative feedback control of the oxygen ion current of a standard cell and the detection of an oxygen ion current sequentially by time-sharing. SOLUTION: In an oxygen shading cell 1, a standard cell 12 and a detection cell 13 have platinum electrodes 15, 16, and 20 that oppose one another while sandwiching a zorconia solid electrolyte 14. The electromotive force of the standard cell 12, a bidirectional negative feedback current for making constant the electromotive force, and an oxygen ion current that is correlated to an air/fuel ratio signal are inputted to a microprocessor 31. The bi-directioinal negative feedback control of the oxygen ion current and the detection of the oxygen ion current are performed sequentially by time-sharing.  The distribution processing of the proportional distribution, integration distribution, and differential distribution of the amount of negative feedback is performed by a momentary value that is obtained by the time-sharing, thus reducing the transition response delay for detecting the air/fuel ratio and improving the air/fuel ratio control accuracy of a mixed air and hence optimizing the exhaust, fuel consumption, and output due to an operation condition change.

Filed: 1985-05-17
Abstract: PURPOSE:To make it easy to adjust lateral positioning of picture plane by outputting information from a picture plane position setting means to the pro gram counter which is used for a frame counter means. CONSTITUTION:When the start pulse that is a command signal to start sampling of a still picture image signal is input to frame counter means 4a, the output from frame counter means 4a is initialized at the value set by screen position setting means 5. Here, the screen position setting means consists of a plural number of switches and is designed so that a setting value can be changed by changing a combination of on and off operations of switches. Now, letting a value set by picture plane position setting means 6 be (k) with the assumption that when the value of sampling means 3 is (q) the carry output occurs, the position of the right end of a printed picture plane coincides with the position of the (q-k)th dot clock counted after horizontal synchronous signal comes. Therefore, when changing (k) the lateral position of the printed picture plane can be arbitrarily adjusted.

Abstract: PURPOSE:To suitably select the elastic layer of an elastic roller and make possible high speed developing by pressure contacting the roller to an electrostatic latent image carrier, squeezing out and supplying developing solution through its compression and restoration and recovering excess solution thereby performing developing. CONSTITUTION:A developing roller 14 is partly dipped in developing solution 12 in a liquid vessel 13 and a refresh roller is pressure contacted thereto. The developing roller 14 comprises providing a porous elastic material 17 such as foamed polyurethane or other around the central body 16 and enclosing said material with netting 18 in endless form. When a photosensitive drum 6 and developing roller 14 are pressure-contacted and revolved, the developing roller 14 contains the developing solution sufficiently and makes contact with the photoreceptor 6 to form a nip part a. Developing is accomplished by the developing solution squeezed out (c part) and the developing solution in the a part. At the time when the developing roller 14 detaches from the photoreceptor 6, the elastic material 17 restores from the compressed state and therefore it draws in the excess developing solution near the photoreceptor and further the exchanging and replenishing of the developing solution is accomplished through pressure contact of the refresh roller 15. The layer thickness of the abovementioned elastic body 17 is made 1.0-10mm, whereby solution suction action is made sufficient and high speed developing made possible.
