Title: Motor-driven blower
Inventor: FUKUMOTO MASAMI
IPC: F04D29/44
Filed: 1992-02-07
Abstract: PURPOSE:To prevent the generation of circulating flow to improve the operating efficiency of a blower by making the distance of a casing from an impeller at a mid-point larger than the distance at an impeller suction part and the distance at a discharge part in relation to the position-relationship between the casing and the front shroud constituting an impeller. CONSTITUTION:When an impeller 18 is driven and rotated at high speed by a motor 13, air is sucked in from a suction part 12 and then discharged from a discharge part 19. A part of the discharged air flows into a spacing 20 between a front shroud 15 and a casing 11 since the pressure on the suction part 12 side is low. The spacing 20 is formed so that the distance A of the casing from the impeller in the neighborhood of the suction part 12 and the distance B in the neighborhood of the discharge part are smaller than the distance C in the neighborhood of an intermediate part, and the size of the spacing at C point is a maximum. As a result, eddy flows are generated in the casing 20, and the existence of the eddy flows makes it difficult for the air flow to enter the spacing. Thus, the air can be prevented from passing through the spacing 20 to circulate toward the suction side, and thus the operating efficiency of a blower can be improved.

Title: Relative position recognizing method of vehicle
Inventor: YOSHIDA KATSUHIKO
IPC: G05D1/02
Filed: 1994-02-21
Abstract: PURPOSE:To reduce the posibility of mis-conception and reduce the effect of a body with a high image element value except a discrimination body by finding out the image element value for every block by dividing the central part in a lateral direction of a filming image into a plural number in a lougitudinal direction and setting the central coordinates of a peek value in a discrimination body position by preparing the histogram in a filming image lateral direction. CONSTITUTION:The discrimination body 5 of a side line 4 is filmed by a filming device 2 installed on the side surface of a vehicle 1 and its position is estimated. Respective image element values between Y0-Y10 upto X30-X60 are added by a histogram obtained by the image. The histograms of respective image element values upto Y0-Yn for every image element group are prepared similarly. BM is judged as the discrimination body 5 when the difference between the maximum value BM of the histogram and next maximum value BN is larger than a threshold value and a coordinate YA and a coordinate YB in a Y direction are found out and (YA+YB)/Z is made the central position of the discrimination body 5 as YC. Consequently, even if any body with its image element value equal to that of the discrimination body exists, its effect is small and the posibility of mis-conception is reduced in a total image element value.

Title: Method and device for picture binarization
Inventor: KIKUCHI OSAMU
IPC: H04N1/403
Filed: 1993-02-10
Abstract: PURPOSE:To generate binarization data with excellent picture quality from an intermediate tone picture by using the error spread method. CONSTITUTION:After input data are corrected by a gamma correction circuit 13, a partial pattern comprising plural picture elements in longitudinal and lateral directions is extracted by counters 20, 21, and a weight conversion circuit 15 has a means converting an input closer to a binarization threshold level into a value closer to a black level and a means converting an input closer to a binarization threshold level into a value closer to a white level and the two conversion means are applied to convert the density of the picture elements so that a cyclic result is obtained in the longitudinal and lateral directions of the said partial pattern and the result is binarized by the error spread method. Since the two conversion means are applied to the pattern cyclicly in the longitudinal and lateral directions, even when noise or uneven density is in existence in an area having a density where a ratio of white and black levels is 1:1, white and black picture elements are outputted cyclicly in both the directions as the result of binarization and excellent binarized picture elements are obtained.

Title: Roll film carrier
Inventor: BUNGO KENICHIROU
IPC: G03B21/11
Filed: 1990-01-31
Abstract: PURPOSE:To inhibit the feeding stop of a microfilm owing to that its emulsion surface side is attracted to a pressing glass by changing the position of the microfilm feeding surface by a mechanism for switching the position of the feeding surface of the film and pressing the non-emulsion surface side of the microfilm against the pressing glass. CONSTITUTION:When the image of the microfilm 1 is perused, or when retrieval is performed while perusing the image, a pair of pressing glasses 9 and 10 is in a closed state. In the case that the retrieval is performed while perusing the microfilm 1, that means, in the case that the film 1 is fed at a low speed or at an extremely low speed while keeping the pair of pressing glasses 9 and 10 closed, the position of the feeding surface of the film 1 is changed by the mechanism for switching the film feeding surface position so that the non-emulsion surface side of the film 1 may come into contact with one of the pair of the pressing glasses 9 and 10 (for example, in the case that the non-emulsion surface looks upward, so that it may come into contact with the upper glass 9, and in the case that it looks downward, so that it may comes into contact with the lower glass 10). Thus, the attraction of the emulsion surface side of the microfilm to the pressing glass does not prevent the film from being fed irrespective of the emulsion side direction of the microfilm.
