Title: Rolling bearing unit with tone wheel
Inventor: OMI ISATO
IPC: G01P3/487
Filed: 1995-12-13
Abstract: PROBLEM TO BE SOLVED: To prevent a tone wheel which is composed of a multipole magnet from being damaged or from coming off due to an insufficient supporting force. SOLUTION: A support ring 29 is put on and fixed to the shoulder section 28 of an inner race 21 which rotates together with a hub 14. A tone wheel 33 is put on and fixed to the large-diameter cylindrical section 31 of the ring 29 by interference fit. Since the diameter of the cylindrical section 31 can be expanded elastically, the tensile stress applied to the wheel 33 in the circumferential direction does not become excessive. In addition, the difference between the amounts of thermal expansion of the ring 29 and wheel 33 can also be absorbed by the elastic deformation of the cylindrical section 31.

Title: Method and apparatus for determining crossing area of solid matter
Inventor: FUIRITSUPU RODONII RATORIFU
IPC: G01F17/00
Filed: 1988-12-22
Abstract: PURPOSE: To determine the cross-sectional area of turbine blade by putting a solid object into a liquid of a specified volume, measuring variation of the volume of displaced liquid, and calculating the cross-section of solid object as a function of immersed length. CONSTITUTION: A tank 10 is filled with a liquid 12 (e.g. water) up to level L, and a blade 14 is suspended from an immersing means. The immersing means is constructed by connecting the blade 14 with a weight 26 of corresponding weight through a wire 24 and entraining the wire 24 about pulleys 18, 20, 22. The pulley 20 is moved by a moving means 28 and the blade 14 is immersed into the liquid 12. Apparent variation of weight dW of the blade 14 due to buoyancy is determined by means of a balance 30 supporting the weight 26 and a signal corresponding to weight variation per unit time dW/dt is inputted to a computer means 32 along with dy/dt. Since the (dW/dt)/(dy/dt) is proportional to the cross-sectional area of blade 14, cross-sectional area of blade 14 can be determined for the increment of length along the length (y) of blade 14 immersed into the liquid 12.

Title: Ultrasonic liquid level measuring device
Inventor: USHIJIMA TAKEO
IPC: G01F23/28
Filed: 1990-11-27
Abstract: PURPOSE:To accurately measure a wide range of liquid levels by placing an ultrasonic transmitter/receiver which transmits ultrasonic pulses into the liquid in a liquid tank or a liquid level indicator tube and receives reflected waves from a liquid surface inside or at a lower part outside the liquid tank or the liquid level indicator tube. CONSTITUTION:An ultrasonic transmitter/receiver 15 is placed oppositely to a liquid surface 3a on a lower face of a lower fixing metal 4 of a liquid level indicator tube 2, while the transmitter/receiver 15 is attached to the lower fixing metal 4 by a cover-like fixing jig 16. The transmitter/receiver 15 generates for example ultrasonic pulses of 2.25 MHz. The ultrasonic waves generated from the transmitter/receiver 15 pass through the lower fixing metal 4 and the liquid 3 and are reflected on the liquid surface 3a to be received by the transmitter/receiver 15 via the same route. By thus measuring a liquid level with the ultrasonic waves propagated in the liquid, linearity in a relation between measurement time and a measured distance is better than a case where the ultrasonic waves are propagated in the air, thereby improving measurement accuracy.

Title: Ultrasonic member
Inventor: TAKEUCHI SHINICHI
IPC: C04B41/48
Filed: 1991-12-10
Abstract: PURPOSE:To stably measure a surface with high accuracy even when the surface is highly rough by mounting a gel sheet formed of a high polymer gel-like elastic substance on a holder and propagating ultrasonic waves to an object to be inspected through the gel sheet. CONSTITUTION:The title member 30 houses a gel sheet 1 formed of a high polymer gel-like elastic substance in a holder 2 and secures the sheet 1 with a lid 3. Nondestructive inspections are performed or the solidified state of asphalt is measured while the sheet 1 is pressed against an asphalt-paved road 40, etc., and ultrasonic waves are propagated to the road 40 through the sheet 1. The acoustic characteristic of the sheet 1 shows values close to those of water with respect to the acoustic velocity and acoustic impedance and a low damping factor. Since the sheet l is flexible, the coupling member can be stuck to the surface of the road 40 even when the surface is highly rough. Therefore, the propagation loss of the ultrasonic waves can be reduced and the measurement sensitivity of the member can be improved remarkably. In addition, since the sheet 1 has high stability and a shape maintaining property, the sheet 1 can be repeatedly used for surfaces to be inspected even when the surfaces are highly rough and high durability is obtained from the sheet 1.
