Title: Recognition device for character string
Inventor: TODAKA CHIAKI
IPC: G06K9/20
Filed: 1994-03-22
Abstract: PURPOSE:To surely read a character string for any arbitrary number of digits to be the object of data processing due to a computer by setting a reading area inside a range within two pieces of vertically adjacently arranged character strings. CONSTITUTION:A reading start mark 12 is displayed just before a character 10a at the head of a character string 10-1, and a reading end mark 14 is displayed just behind a final character 10n. A reading area 30 surrounded by a contour line 26 is set inside the range to be an interval 2L within two character strings concerning an intercal L of the character string 10-1 to be recognized. Thus, since the reading area 30 is set, probability in the case of simultaneously recognizing two character strings 10-1 and 10-2 is reduced but probability to position the entire single character string 10-1 inside the reading area 30 is made higher. When two character strings are positioned inside the reading area 30 at the same time, only one character string is decided valid or both the character strings are decided invalid.

Title: Device for preventing generation of resonance sound in cavity
Inventor: NAKANISHI TOSHIO
IPC: F16L55/04
Filed: 1995-03-10
Abstract: PURPOSE:To have an effect on the prevention of resonance sound generation for frequencies in a wide range by disposing a sound damping plate having the plane crossing the axial direction of a main pipe to extend inside a cavity in the proximity of the opening part of the cavity formed to cross a main pipe. CONSTITUTION:A sound damping plate 7 having the plane crossing the axial direction of a main pipe 1 to extend inside a cavity is disposed in the proximity of an opening part 4 of the cavity 2 formed to cross the main pipe 1. The sound damping plate 7 has a linear shaped end face 9 on the inner surface side of the main pipe 1 so that both ends of the end face 9 coincide with corner parts of the inner surface of the main pipe 1 and the opening part 4 of the cavity 2. Thus, the exciting frequency of a swirl S generated on the interface between fluid 3 in the cavity 2 and fluid 3 flowing in the main pipe 1 is disturbed by the sound damping plate 7. Thus, since the fluid 3 in the cavity 2 is disturbed, the resonance with an air column resonance frequency which the cavity 2 has is not generated so that the generation of resonance sound caused by the cavity is prevented in a wide range of frequency.
