Title: Ultrasonic wave probe and blood flow measuring instrument
Inventor: OTA MASAYA
IPC: A61B8/06
Filed: 1990-11-30
Abstract: PURPOSE:To automatically detect blood flow by searching a blood vessel position by a 1st probe and identifying the central position of the blood vessel by automatic scanning of a 2nd probe which is so arranged as to intersect orthogonally with the longitudinal direction of a vibrator. CONSTITUTION:The 1st probe 3 is so fixed that its scanning direction and the longitudinal direction of the blood vessel 2 intersect approximately orthogonally with each other. The axis of the 2nd probe 4 where the vibrator 10 is arranged is likewise in the direction to be subjected to electronic linear scanning and is so arranged as not to intersect orthogonally with the longitudinal direction of the vibrator 10. The 2nd probe 4 is disposed by inclining the same. The blood flow direction is identified as well from the direction connecting the central position 34 of the blood vessel 2 obtd. at the time of scanning the 1st probe 3 in the scanning direction 35 and the central position 36 of the blood vessel 2 at the time of scanning the inclined 2nd probe 4 in the direction 37. A beam 7 for Doppler is radiated from the used element group 40 of the 2nd probe 4 and an ultrasonic pulse Doppler measurement is carried out. The angle theta in the blood flow direction 38 is determined from the previously determined blood flow direction of the blood vessel and the waveform of the blood flow velocity subjected to correction at this angle is obtd.

Title: Image forming method
Inventor: OSAWA SHIGENOBU
IPC: G03G13/09
Filed: 1989-12-28
Abstract: PURPOSE:To obtain the image of high image density without positive memory by regulating the ratio Vs/Vp of the linear velocity Vs of a developer carrier to the linear velocity Vp of a latent image carrier within a specified range. CONSTITUTION:In a state where toner which is not transferred to be left and firmly adheres to the surface of the latent image carrier 1 is scattered with mechanical force by a magnetic brush formed on a developing sleeve 10 having a magnetic body inside, the toner is moved to the developer carrier 10 in virtue of the surface potential of the latent image carrier 1 of a non-image part and the electric field of developing bias. The cleaning effect for the toner which is not transferred to be left is largely influenced by Vs/Vp, and the excellent cleaning effect for the toner which is not transferred to be left and the high image density are accomplished by limiting it within 3.0<=Vs/Vp<=7.0. Thus, the image of the high image density without the positive memory is formed without using a cleaning device.

IPC: B21D37/20
Filed: 1996-12-04
Abstract: PROBLEM TO BE SOLVED: To quantitatively evaluate the size of a wrinkle which is faulty surface configuration in press forming process independently of individual variation, by setting a region where size difference from that of standard part (metal mold) is more than given value, and evaluating the surface configuration based on the difference between area of the set region and standard area (standard area of a metal mold). SOLUTION: Trunk lid panel 19 and wrinkles 20 during forming are visually shown on the screen of a display. When the size difference between real length of a cross section of the trunk lid panel 19 and standard real length of metal mold side as standard value is more than a redefined value, the cross section is judged to have wrinkles 20, and when the difference is less than the predefined value the cross section is judged to have no wrinkle. Then a boundary line between estimated regions α, β is determined, where the region α is on the side of trunk lid panel 19 and the region β is a standard metal mold side region which faces the region α vertically. Area difference is derived by subtracting total area of the region α by standard area of entire standard region β.  By considering the area difference as quantitatively estimated value which represents the size of the wrinkle 20, the wrinkle is evaluated quantitatively.
