Title: Air-fuel ratio feedback control for internal-combustion engine
Inventor: HASEGAWA SHIYUNPEI
IPC: F02D45/00
Filed: 1982-05-06
Abstract: PURPOSE:To improve operating characteristics of an internal-combustion engine, by employing an arrangement wherein an operating range where an air-fuel ratio feedback control is performed is divided into a plurality of zones, calculation is made in every zone with an average value of an air-fuel ratio correcting factor which may vary in response to a detected value of O2 sensor output, and selection is made in every non- feedback control zone with an approximate correcting factor. CONSTITUTION:A control device adapted to control an air-fuel ratio of suction air-fuel mixture in response to operating parameters such as an engine speed, a negative pressure in an inlet tube and the like functions to effect a feedback of an air-fuel ratio with basis on a detected value from an O2 sensor under such operating conditions wherein an engine speed and a negative pressure fall within preset zones. A feedback control zone is divided into three zones I -III, and for every zone an average value of air-fuel correcting factor is calculated from a detection value of the O2 sensor. An air- fuel ratio correcting factor for an idling zone, a throttle full-opening zone and a partial lean zone where a feedback control will not be performed is respectively determined as an average value obtained in three zones I -III, and thereby selecting a value most appropriate for the operating zone.

IPC: G06F3/12
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To improve reliability, to simplify the constitution of a circuit and to decrease the cost by transferring image data from a controller with a single main-scan synchronizing signal, to reduce the number of signals transferred from the controller. SOLUTION: A host computer 20 transmits data of printer page prescribing language, etc., (in general, a postscript, etc., are known) to the printer controller 21. This printer controller 21 receives the image data by a command received from the host computer 20, expands the received image data into bit map data and simultaneously, transmits the bit map data to a printer engine 22, in synchronization with a synchronizing signal from the printer engine 22. In other words, the image data from the controller can be transferred with the single main-scan synchronizing signal. Thus, the number of the signals transferred from the controller can be reduced and the reliability can be improved.

Title: Preparation of semiconductor device with embedded joining
Inventor: PALMIERI MICHELE
IPC: H01L21/822
Filed: 1995-03-31
Abstract: PURPOSE: To reduce the dependency on the process parameters of the concentration and/or depth of a buried region, by allowing a second impurity addition stage to have a first sub-step for performing implantation with a low energy and a second sub-step for performing implantation by a low amount of addition and a high energy. CONSTITUTION: When a semiconductor device with a buried junction is manufactured, the impurity in a first format (arsenic) and a second formal (boron) is successively introduced into a silicon chip by the first and second impurity addition stages. An introduced impurity is diffused by a high-temperature treatment, thus forming first and second regions 32 and 33. The amount of impurity to be added and an implantation energy are at a level so that the conduction format (N) of the first region 32 cannot be canceled or inverted, and a concentration at the second region 33 essentially depends on only a second implantation.
