Title: Air fuel ratio control device and air fuel ratio control method
Inventor: NAKAGAWA SHINJI
IPC: F02D45/00
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To obtain a well stabilized air fuel ratio control at the time of idling when it is applied to an in-cylinder injection engine or a lean mixture burning systemengine. SOLUTION: Whether is being an engine idles or not, is judged (STEP 1), whether an absolute value of the difference between a present injection quantity-signal T1 and a fixed time preceding injection quantity-signal TIO exceeds a fixed value or not, is judged (STEP 3), sampling of a signal obtained by an air fuel ratio sensor is performed while the above fixed value is not reached by means of STEP 3, and the frequency-analysis of a signal to be obtained after a fixed time is performed (STEP 6). When the air fuel ratio-signal is frequency-analyzed and a spectrum above a fixed value is detected, the frequency of the spectrum is detected (STEP 6), and a correction factor (f) is calculated based on the detected frequency (STEP 8).  A value obtained by adding the correction factor (f) in a direction to cancel the change, to the injection quantitysignal TI, is regarded as a final injection quantity-signal (STEP 9). Thus, a stabilized fuel injection, which is unaffected by noise, can be performed, and the change in the air fuel ratio at the time of idling can be reduced.

Abstract: PURPOSE:To easily realize a thin layer of a p-type buried layer used to suppress a short-channel effect by a method wherein the p-type buried layer is formed by a multiple ion implantation operation of carbon and inert impurities. CONSTITUTION:A mask 22 for ion implantation use is formed on the main surface of a semiinsulating GaAs substrate 21 by using a resist or the like. C ions are implanted at a prescribed acceleration voltage and at a prescribed dose by using the mask 22. Then, Ar ions are implanted at a prescribed acceleration voltage and at a prescribed dose by using the same mask 22. A multiple ion implantation layer 24 of C and Ar is formed. In succession, ions of n-type impurities, e.g. Si or the like, are implanted at a prescribed acceleration voltage and at a prescribed dose by using a mask whose pattern nearly coincides with the mask 22 for ion implantation use; an implantation layer 23 is formed. After that, ions of e.g. Si are implanted into a region to form an n-type high- concentration layer for a source and a drain at a prescribed acceleration energy and at a prescribed dose; after that, a lamp annealing operation is executed in order to electrically activate impurity atoms in the n-type implantation layer 23, the p-type implantation layer 24 and the n-type high-concentration implantation layer for the source and the drain; a p-type buried layer is formed.

Title: Method for multipole magnetization on resin magnet
Inventor: KENMOCHI KATSUE
IPC: H01F13/00
Filed: 1980-02-06
Abstract: PURPOSE:To make it possible to make magnetic field orientation and magnetization alternately in  a die, by making use of the gap between magnetic paths and the extent of intensity of the generated magnetic field. CONSTITUTION:Inside a cavity 8 a core 9 of magnetic material is mounted, while outside of it a  nonmagnetic plate 10 is mounted. On the outer circuit of the plate, concave parts and convex  parts are formed corresponding to the number of poles to be magnetized. Further on the outside  of the plate 10, a magnetic plate 11 is mounted which has convex parts and concave parts to  mate with the concave parts and convex parts of the plate 10. While an electric current is being sent to form a necessary magnetic field orientation in the cavity, melted resin magnet is injected to  fill the cavity, cooled and hardened. Temporarily the strong magnetic field is switched off, then a  reverse current is sent to form a feeble magnetic field. At this time, where the gap is narrow  higher counter magnetomotive force than the coercive force is applied to magnetize to obtain a  polarity reverse to the stage of the orientation, and the magnetization is performed contrary to the  initial disposition, and where the gap is sufficient, the counter magnetmotive force is less than the  coercive force, so the same polarity as in the stage of orientation is retained. Thereafter the electric current is switched off to take out the molded material. Thus a magnet magnetized on the outer  circuit as desired can be obtained.
