摘要： a limiting current type oxygen concentration sensor element includes a measured gas side electrode formed at one side of a solid electrolyte, and a diffusion resistance portion formed on the measured gas side electrode to provide diffusion resistance to passing measured gas therein. The diffusion resistance portion includes a concave portion formed at a position at least corresponding to a position of the measured gas side electrode. In the concave portion, a porous trap layer is disposed to trap contamination in measured gas. The side wall of the concave portion contacts with the trap layer. The area of a contact surface becomes larger than that without the concave portion, which can effectively prevent the trap layer from being peeled off and dropping down. The trap layer can be easily made thicker. By changing the depth of the concave portion appropriately, diffusion resistance of the diffusion resistance portion can be easily adjusted.

摘要： A vibration damping device for mounting between two spaced portions of a vehicle for absorbing road forces exerted on the vehicle. An inner metal cylindrical housing forms an internal piston chamber and is connected at one end to one portion of the vehicle, with the outer end of the rod of a piston which is slidably mounted within the piston chamber, being connected to the other portion of the vehicle. An outer housing surrounds a portion of the inner housing and forms a fluid transfer duct between fluid chambers formed on opposite sides of the piston within the piston chamber. An electrode is mounted on an inner surface of the outer housing and is electrically isolated therefrom and communicates with the fluid transfer duct for applying a voltage across the duct to affect the viscosity of an electrorheological (ER) fluid flowing therethrough to increase the damping force of the device.

摘要： A vibration damping device includes axially spaced first and second end members adapted to be mounted on spaced apart structures. An intermediate member is mounted within an open end of the second end member. A center member consisting of a rigid tube having a hollow bore and a lower piston is connected to the first end member and extends through the interior of the intermediate member. The tube forms an annular orifice which extends about a rigid electrode rod which extends through the rigid tube and which is also connected to the first end member and piston but electrically isolated therefrom. A pair of elastomeric sleeves extend between the intermediate member and first end member and between the intermediate member and the piston to form a pair of fluid chambers communicating with the orifice and adapted to contain an electrorheological fluid. Each of the sleeves has a rolling lobe with circular centers and different radii of curvature. However, the circular centers of the rolling lobes lie on a common imaginary axially extending cylinder whereby the effective areas of the fluid chambers remain substantially equal as the device moves between jounce and rebound positions to reduce the spring rate effect on the damper. Even though the rolling lobes have the same circular centers the radii of the lobe forming walls are different which enables nesting of the piston within the intermediate member to reduce the axial height of the device without affecting its stroke length.

摘要： Magneto-optical disk recording and reproducing devices and actuators and distance detectors for use therewith are disclosed. The magneto-optical disk device includes a bimorph type actuator or an electromagnetic actuator for driving the magnetic head of the magneto-optical disk device. The bimorph actuator has a metallic shim having a width that varies with respect to the longitudinal distance in inverse proportion to the normal function of the first or the second free natural vibration mode. Alternatively, the bimorph type actuator has a recess formed on a bimorph element to expose a piezoelectric portion which outputs a voltage corresponding to the acceleration of the vibration of the actuator. The driver circuit of the actuator reduces the driving voltage when the frequency of the voltage generated at the recess comes into the neighborhood of a higher resonance frequency of the actuator. The optical distance detector comprises a light-emitting diode and a pair of photodiodes which detects the amount of light incident thereon after the light is reflected from a surface of an object the distance to which is measured. The geometric parameters of the photodiodes are selected such that the output of a first photodiode decreases as the measured distance increases while the output of a second photodiode increases as the measured distance increases. Thus, the normalized differential output of the two photodiodes, from which the measured distance is determined, varies substantially linearly with respect to the measured distance. In preferred forms, the photodetectors have stepped concentric configurations so that small distances can be measured accurately and efficiently.

摘要： An optical type information record carrier is disclosed which includes an arrangement wherein the depth of the guide grooves is selected to be about (2N+1).lambda./8n (N=1, 2, 3, . . . ) and the inclination angle of the wall surface of the carrier is steep enough to ensure that the information recording medium will not adhere to the wall surface of the guide grooves, or will only adhere very weakly if it does adhere. Thermal conduction at the wall surface of the guide grooves is prevented so that extension of the recording bits is restricted.

摘要： A device for driving and controlling an optical head by forming a spot of a light beam on an optical disk having a plurality of tracks and detecting light from the spot reflected on the optical disk by a pair of optical detectors disposed in the head. This device has: a head actuator for moving a movable portion of the optical head in the radial direction of the disk; a speed detector for detecting the track-crossing speed of the spot from outputs from the optical detectors; a reference speed generator for generating, while accessing to a target track, a reference moving speed signal in accordance with the distance to the target track obtained from the outputs from the optical detectors, the movable head portion being moved on the basis of the reference moving speed signal so that the speed of the movable portion decreases at a position near the target track before the light beam spot reaches this track; a speed error detector for obtaining the difference between outputs from the reference speed generator and the speed detector; and a magnification change circuit adapted for amplifying the outputs from the reference speed generator and the speed detector by a predetermined multiplying factor when the distance between the light beam spot and the target track, or the crossing speed of the spot, becomes smaller than a predetermined value, the magnification change circuit also being adapted for outputting the difference obtained by the speed error detector after multiplying it by the reciprocal of the multiplying factor. The head actuator is driven on the basis of the output from the error detector so as to control the speed of the movable head portion.
