Filed: 2000-07-05
Abstract: PROBLEM TO BE SOLVED: To obtain an underwater walking exercise machine which is compact and structured simply to improve reliability and to reduce costs, which reduces burden to a person having functional disorder at his loin or legs by his weight and is effective for function restoration. SOLUTION: As for the underwater walking exercise machine 10, a tub 12 having a walking machine 50 installed on its bottom is filled with water and the person 90 in the state of holding a body trunk holding auxiliary bar 70 to keep his posture and mounting a body trunk holding belt 80 to hold his weight does pseudo walking exercise on a walking machine 50. Since the weight of the person 90 is held by the buoyancy of water and the belt 80 in this case, even the person 90 having functional disorder in his loin or legs has his pain at a disorder site reduced and can do the pseudo walking exercise. Since this exercise is against the flowing resistance of water, a function restoring effect is also excellent.

Title: Method and apparatus for adaptive wall filtering process in spectrum doppler ultrasonic imaging
Inventor: MO LARRY Y L
IPC: G01S15/89
Filed: 2000-07-06
Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for performing an adaptive wall (high-pass type) filtering process for eliminating a low-frequency clutter in spectrum Doppler I/Q data before FFT process. SOLUTION: The I/ Q data is passed through a low-pass filter. The total power of the outputs of the low-pass filter is calculated. Using a system noise model, average system noise power in the output of the low-pass filter is anticipated. The noise power provides a noise threshold which serves as the measure of clutter power existing in a current FFT packet. When there is no significant clutter, wall filter selecting logic selects a minimum wall filter cutoff frequency stored in a filter coefficient lookup table (LUT). When there is significant clutter power, the average and dispersion of clutter frequencies over the FFT packet are estimated and inputted to the filter selection logic to select a filter cutoff frequency which is best suited for the current clutter signal.

Title: Image-forming device
Inventor: NOMURA YUJIRO
IPC: G03G15/02
Filed: 2000-08-04
Abstract: PROBLEM TO BE SOLVED: To provide an image-forming device, capable of more effectively cleaning an electrifying member, taking into considertion the tilting property of a brush. SOLUTION: A contact/separate direction A, where the brush of a cleaning member 10 is operated to contact with/separate from the electrifying member 9 and a tilting direction C, where brush flocked fibers 10a are tilted by the tilting property, are set to be the same each other.

Title: Flexible seal of liquid level operable control valve
Inventor: SCHRAMM JOHN G
IPC: F02M37/00
Filed: 2000-08-11
Abstract: PROBLEM TO BE SOLVED: To provide a float valve for improving fuel feeding performance by controlling delivery of fuel vapor from a fuel tank. SOLUTION: A float 50 moves between an initial position having a fuel level not more than a prescribed level, an intermediate position and the final position not less than the prescribed level. An outside seal material of an elastomer seal material 60 positioned between the float and a vapor outlet opening 80 sealably engages when the float reaches the prescribed level, and an inside seal member sealably engages when the float is not less than the prescribed level. Thus, the float allows a flow of the fuel vapor at a first speed in the initial position of the float, and the elastomer seal material allows the flow of the fuel vapor via the vapor outlet opening at a second speed lower than the first speed, and prevents the flow of the fuel vapor when a float member is in the final position.
