Title: Ringer detecting circuit
Inventor: CHIKASAWA TSUTOMU
IPC: H04M7/00
Filed: 1989-01-20
Abstract: PURPOSE:To eliminate malfunction due to a noise by rectifying the voltage on a connecting means, which connects with an exchange, on a full-wave basis, removing noises of high frequency, and delaying the voltage by a specific number of pulses and detecting a ringer. CONSTITUTION:The voltage is rectified by a full-wave rectifying circuit 21 and inputted to a photocoupler 22. Then noise components higher than the cut-off frequency of a low-pass filter 31 are removed and only low frequency components lower than the cut-off frequency are passed and inputted to an (n)-stage shift register 41 and a monostable multivibrator 51. A call signal which arrives repeatedly is inputted to a two-stage shift register 41 and a monostable multivibrator 51. When >=3 pulses are inputted, the two-stage shift register 41 outputs '1'. consequently, the two-stage shift register 41 generates no output with <=2 pulses, so a ringer detecting circuit which does not malfunction is formed.

Filed: 1999-01-21
Abstract: PROBLEM TO BE SOLVED: To prevent air bubbles from staying in a boundary part without deteriorating rotary precision by forming an unbalanced herringbone-shaped radial dynamic pressure generating groove in the axial line direction in a radial bearing part and forming a thrust dynamic pressure generating groove, in a thrust bearing part for causing a lubricating fluid to move toward the rotary axial canter of a rotary member. SOLUTION: Each herringbone shape groove 16 formed in each radial bearing part 18 is made unbalanced in the axial line direction, by linking mutually opposite direction spiral grooves 16a and 16b so as to generate dynamic pressure for moving the lubricating fluid 14 toward each thrust bearing part 22 when a rotor hub 2 and a shaft 4 are rotated. Each spiral groove 20 formed in each part 22 generates dynamic pressure for moving the lubricating fluid 14 in the axial direction, when the rotor hub 2 and the shaft 4 are rotated. The herringbone-shaped groove 16 formed in each radial bearing part 18 prevents the stay of the air bubbles in the neighborhood of the boundary part between the radial bearing part 18 and the thrust bearing part 22.
