IPC: G11B23/087
Filed: 1993-12-17
Abstract: PURPOSE:To eliminate such a state that a case main body is damaged and it becomes unsightly as it abuts on a positioning member to the utmost. CONSTITUTION:When a cover 14 arrives at the prescribed position of a magnetic recording or reproducing device, the positioning member enters the inside of the notched parts 22a and 22b of the cover 14 and abuts on the tip surfaces 24a and 24b of projecting pieces 23a and 23b integrally formed with the case main body 11. Then, the pressing depth of a tape cartridge is regulated. Since recessed parts 25a and 25b are formed around the pieces 23a and 23b, the positioning member is not caught by the recessed parts 25a and 25b and only the tip surfaces 24a and 24b of the pieces 23a and 23b are damaged caused by the abutting on the positioning member. Even the damage caused on the tip surfaces 24a and 24b of the pieces 23a and 23b becomes inconspicuous by the shadow of the recessed parts 25a and 25b and the unsightly state is reduced. Even when the recessed parts 25a and 25b are damaged, the unsightly state is not conspicous because they are formed to be recessed. Then, the appearance is excellently maintained.

Title: Air-fuel ratio controller for engine
Inventor: KADOTA YOICHI
IPC: F02D45/00
Filed: 1990-11-21
Abstract: PURPOSE:To enable a high-precision air-fuel ratio control by detecting the variation in characteristics of each injector on the basis of an air-fuel ratio correction value obtained at the time of stopping the feed-back correction for air-fuel ratio with respect to an injector mounted to each cylinder. CONSTITUTION:It is now assumed that the number of air cylinders is 4 for example. Then, a mean value of the feed-back correction factors is calculated from the correction factor of one presently checked air cylinder, with respect to which the feed-back operation is stopped and no feed-back control is made, and the correction factors of the remaining three air cylinders with respect to which the feed-back controls are made. Resultantly, if comparison is made between the mean value of the feed-back correction factors and a mean value of the correction factors obtained when feed-back control is made of all the four air cylinders, it is possible to detect the variation in the characteristic of a presently checked injector 6. Thus, supply of an adequate amount of fuel corresponding to the variation of each injector 6 becomes possible, so that a highly precise air-fuel ratio control becomes possible.
