Abstract: A boron carbide sintered body of which the surface is coated with a membrane composed of SiC, Si₃N₄ or a mixture of SiC and Si₃N₄. The boron carbide sintered body comprises 8 to 35 wt. % of carbon short fibers and/or silicon carbide whiskers in the sum, 0 to 20 wt. % of silicon carbide and/or carbon in the sum, and the remainders being boron carbide and unavoidable impurities. In the sintered body of the invention, since B₄C constitutes the principal part, the sintered body has a low specific gravity and nevertheless it has a high hardness and a high strength. Moreover, it is excellent in resistance to oxidation at a high temperature imparted by the coating membrane of SiC or Si₃N₄ formed on the outside. The carbon short fibers and silicon carbide whiskers incorporated into the sintered body check the progress of cracks when they are produced in the sintered body, and improve the fracture toughness.

Abstract: A percutaneous implant device (20) has a main body portion (30) and a flange (56) extending outwardly to a free edge (60) thereof from the main body portion. The flange (56) can have a thickness that decreases toward the free edge and the stiffness of the flange (56) decreases away from portions of the flange nearest the main body portion (30) to portions of the flange nearest the free edge (60). This stiffness characteristic can be accomplished by a flange density that decreases outwardly or by the flange having a porosity which increases toward the free edge. The thickness and density of the flange can decrease, while the porosity increases, toward the free edge. The thickness and thread count of a textile flange can decrease toward the free edge, or the thickness and packing density of a fibrous flange can decrease toward the free edge.

Abstract: An m- input/n- output (e.g., 2x2) optical fiber switch (10 M ) is disclosed which alters the location of the fibers (20, 22, 24, 26) by the application of an external force. Illustratively, the switch uses a housing with a diamond-shaped opening (11) extending therethrough, with pairs of optical fibers positioned in orthogonally located V-grooves (16, 18). Upon the application of an external force, the fibers are moved into the remaining, vacant V-­grooves (13, 15) formed by the diamond-shaped opening. In a preferred embodiment, a (2x2) switch is magnetically activated. 
     As mentioned above, switching into the alternate (e.g., transmit/receive) state of switch (10 M ) is accomplished by the use of appropriately placed soft magnetic (e.g., permalloy) pieces in conjunction with an applied electrical signal which propagates along a coil (17) encircling switch (10 M ). In one particular configuration, the soft magnetic pieces take the form of rods (46), (48), (50) and (58), (60), (62) which are disposed in V-grooves formed parallel to fiber-holding V-grooves (16) and (18). As shown, a first set of soft magnetic pieces (46), (48) and (50) are positioned within a first V-groove (52) located adjacent to interface (vacant) V-groove (15) of opening (11). The pieces are disposed such that gaps (54) and (56) between the adjacent pieces are substantially aligned with magnetic sleeves (36) and (32). Therefore, upon application of an electrical signal to coil (17) a magnetic field will be created in the gaps, causing sleeves (36) and (32) to be attracted to gaps (54) and (56), respectively. Thus, free ends (E₂₆), (E₂₂) of fibers (26) and (22) will move to occupy interface V-groove (15) such that optical coupling is achieved. In association with the system description, the coupling of fibers (22) and (26) may serve to connect the fiber entering the optical transmitter (fiber 26) to the fiber re-entering the communication ring (fiber 22).

Abstract: The optical recording/reproducing apparatus provided with a dividing optical element which divides a part of the light from a light source and projects the divided light to a moving stage on which an objective lens is mounted, a reflecting optical element which is mounted on the moving stage and reflects the projected light from the dividing optical element, and a photodetector which detects the reflected light from the reflecting optical element, wherein the deviation amount of the moving stage from a reference position is detected on the basis of output of the photodetector. Since the condition when the reflected light is incident upon the photodetector is changed in consequence to the positional deviation of the reflecting optical element as the moving stage is moved, the deviation amount of the moving stage is detected on the basis of the output of the photodetector. The deviation amount of the moving stage can be detected at all times, thereby achieving good tracking control.

Abstract: There is provided an ultrasonic Doppler blood-flow meter which can suppress the occurrence of unwanted frequency components by suppressing the jump of signal to thereby produce images of high quality. A DC feedback circuit (15a; 15b) is provided which negatively feeds back a Doppler deviated signal produced from an integrator (9a; 9b) to the input thereof. The feedback amount of the DC feedback circuit is changed in synchronism with the timing for switching between the B-mode transmission/reception sequence and the Doppler mode sequence to prevent a jump of a signal at the commencement of the Doppler mode. The feedback amount of the DC feedback circuit is made to be different for the gate moving sequence and the Doppler mode sequence, thereby preventing a jump of a transient signal due to a discontinuous input signal at the commencement of the Doppler mode.

Abstract: A PTC device has two electrodes (6) affixed to opposed surfaces. The electrodes consist of a metal foil having a conductive layer (4) on their surfaces that contact the PTC material (1). The conductive layer has a thermal coefficient of expansion intermediate between the thermal coefficients of expansion of the metal foil and the PTC material.
