Title: Supporting leg for audio/video apparatus
Inventor: OBATA KATSUYUKI
IPC: H05K5/02
Filed: 1994-07-19
Abstract: PURPOSE:To suppress resonance due to external vibration effectively by setting the part touching an apparatus at a shifted position. CONSTITUTION:A projecting part 5 touching an apparatus 1 has the central part set at a position shifted from the circular outline of a led body 3, i.e., a position shifted from the center (a) of the leg body 3. A fixing hole 7 for passing a screw 6 is also made at a position shifted from the center (a) of the leg body 3. Since the projecting part 5 and the screw 6 are set at shifted positions, the length of propagation path of external vibration applied to the supporting leg 2 is not constant over the entire circumference of the leg body 3 but different depending on the direction and thereby the vibrating position is shifted slightly thus distributing the resonance. In particular, since ribs 9a, 9c, 10a, 10c, 11b are formed with different length while shifting each other, the phase of vibration can be shifted thus suppressing the resonance.

Filed: 1990-06-26
Abstract: PURPOSE:To enable measurement of elasticity of a bone from the surface of a human body by making a leak surface pseudo longitudinal ultrasonic wave propagating near the surface of the bone-excite and propagate to measure sound velocity by a propagating distance and time when it propagates by a specified distance. CONSTITUTION:When a pulse excitation is performed with an ultrasonic transducer, a plane wave of an ultrasonic pulsethetac is excited and a beam alone impinged at a critical angle among the waves excites a wave of LSSC. The wave propagating by a distance 19 near the surface of a bone is refracted on a cylindrically curved surface 11 and grains to return to the transducer 13. When the wave is observed with an oscilloscope, a reflected pulse 21 on the cylindrically curved surface 11, a reflected pulse 24 on the surface 23 of the bone as produced by a wave 22 impinging vertically into the bone and a pulse produced by the wave propagating near the surface of the bone appear in succession following a leak pulse 20 during a transmission. Here, a time difference is determined between the reflected pulses 24 and 25 on the surface of the bone detector to obtained a distance between the electrically curved surface 11 and the surface of the bone from a lid difference between the reflected pulse 21 and 24, thereby enabling the calculating of sound velocity of the bone.

Title: Picture processing system
Inventor: IKEDA MINORU
IPC: H04N1/40
Filed: 1988-07-05
Abstract: PURPOSE:To exactly detect a binary picture such as s lateral narrow line by deciding a half tone area by using white run length and black.gray run length and gray run length in it on the basis of picture data ternarized into white, gray and black. CONSTITUTION:Multi-level picture data is emphasized in its density by a spatial filter 6, and is ternarized into the levels of white, gray and black by a ternarizing part 7. Next, the white run length (RW) is detected by a white run length detecting part 8, and is inputted to a black.gray run length detecting part 10 and a gray run length detecting part 11 through a run length correcting part 9. The detecting part 10 obtains the black.gray run length (RGB) of a black and a gray picture elements, and the detecting part 11 obtains the gray run length (RG) in the RGB. Then, a condition deciding part 12 decides the area to be the halt tone area when both RGB, RG exceed constants K1, K2. By this method, the area is not decided to be the half tone unless gray in the run in which black and gray are mixed is large to some extent. Accordingly, the binary picture can be exactly detected.
