Title: Airfoil having stall suppressing function due to forcing vibration
Inventor: WYGNANSKY ISRAEL
IPC: B64C27/46
Filed: 1998-06-24
Abstract: PROBLEM TO BE SOLVED: To achieve a more adequate method for suppressing stall of an airfoil by flowing fluid through at least one section on the airfoil in the application of a rotary-wing aircraft. SOLUTION: An airfoil 10 moves through a fluid medium 24 using a front fringe 16 thereof in the head and a rear fringe 18 thereof at the back. When the medium 24 passes the airfoil 10, it is possible to suppress stall of the airfoil 10 by forcing the vibration on the medium 24 at several sections on a surface thereof, for example, the front fringe 16, the rear fringe 18, a position 26 on a top face 12 within one-fourth from the front fringe 16 in a chord 22, a position 28 which exceeds one-fourth, a position 30 on a bottom face 14 within one- fourth, and a position 32 which exceeds one-fourth. This forced vibration is generated by flowing fluid from the inside 20 to the medium 24 at, for example, positions 16, 18, 26, 28, 30, or 32. This stream may be a stream having a net amount of zero.  At this time, forcing vibration is done at a frequency of which stall-hull ratio exceeds substantially 1 to modulate the force of the fluid in the frequency or amplitude.

Title: Floating magnetic head
Inventor: ENOMOTO KENJI
IPC: G11B21/21
Filed: 1994-07-29
Abstract: PURPOSE:To make a slider high in floating height and to increase restoring force at the rolling time. CONSTITUTION:An opposite surface 30 of the slider 28 to a disk is provided with a recessed groove 31 in the middle, and rail surfaces 32A and 32B are formed on both sides of the groove. A depth of the recessed groove 31 is set to <=20mum, for this instance, 5-10mum. Since the depth of the recessed groove 31 of this floating magnetic head 14 is shallower than the conventional head, floating force acts on not only both rail surfaces 32A and 32B but also a bottom surface 31A of the recessed groove 31. Consequently, the floating height is high. Then, since floating force of the bottom surface 31A is smaller than floating force of the rail surfaces 32A and 32B, the restoring force worked at the time of rolling the slider 28 is made large, and hence the slider 28 is immediately returned to be horizontal.

Title: Longitudinal vibration type piezoelectric vibrator
Inventor: NAKAYAMA IWAO
IPC: H03H9/05
Filed: 1983-09-27
Abstract: PURPOSE:To attain small size and low cost by increasing the width of both tips of a main vibration part more than the central width of the main vibration part and to change the frequency over a wide range by having only to change the manufacture conditions. CONSTITUTION:The width W2 of both tips of the main vibration part 10 is increased more than the central width W1 of the main vibration part 10. The provision of wide parts 15a, 15b to the tips of the main vibration part is equivalent to add a mass to the main vibration part. Thus, the frequency is decreased without prolonging the length L of the main vibration part 10. On the other hand, the broadwise size of the main vibration part is changed by changing the crystal etching time. When the width is changed equally to the tip of the main vibration part and the central part by DELTAW, the relation of DELTAW/W2<DELTAW/W1 is established and the equivalent mass at the tip of the main vibration part is changed.
