Title: Power steering gear
Inventor: KANAZAWA HIROTAKA
IPC: B62D6/02
Filed: 1982-10-30
Abstract: PURPOSE:To allow a steering assist power to be selected according to operator's physical strength and his preference, by cutting off drive connection between an engine and an oil pump. CONSTITUTION:When a vehicular speed increases to a value more than a set speed, an output signal from a comparator in a controller 27 is changed to H level, thereby selecting a selector valve 23 to its offset position. As a result, hydraulic oil in a hydraulic oil introducing chamber 22 of a variable pulley mechanism 18 is drained to minimize an effective diameter of a variable driven pulley 20 and render a tensile force of a belt member 21 zero, resulting in disappearance of a frictional force between the belt member 21 and both pulleys 19 and 20. Further, when a reference voltage generator 29 is manually operated to change its output signal, a changeover point from L level to H level of the output signal from the comparator of the controller 27 is varied, thereby allowing the vehicular speed to be varied when cutting a steering assist power.

Title: Fiber optical detecting system
Inventor: MAIKERU EMU SARAUAA
IPC: G01K11/14
Filed: 1986-08-19
Abstract: A fiber-optic system for measuring a desired environmental parameter, such as temperature, is disclosed. The system includes a fiber-optic sensing head that alters light of a prescribed frequency as a function of the environmental parameter to be measured. Light not of the prescribed frequency is not so altered. In a preferred embodiment of the fiber-­optic sensing head, a semiconductor material is positioned between two substantially parallel optical fibers at a distal end of the fibers. One fiber serves as in input channel and the other fiber serves as an output channel. Both fibers approach the semiconductor material from the same direction. Light channeled to the semiconductor material is reflected at the distal end of the input fiber so as to pass through the semiconductor material, and then is reflected again at the distal end of the output fiber so as to pass back out the output fiber. The semiconductor material absorbs the light of the prescribed frequency as a function of temperature. By monitoring the intensity of the light of the first frequency at the output channel, a measurement of the temperature to which the fiber-optic sensing head is subjected can be determined. To remove the influence of input light intensities, fiber attenuation, and the like, from the temperature measurement, lights of two frequencies, only one of which is the prescribed frequency, are selectively directed to an optical detector through the fiber-optic sensing head and through a separate fiber-­optic reference channel. The four measurements thus obtained at the optical detector -- prescribed frequency through sensing head, prescribed frequency through reference channel, non-prescribed frequency through sensing head, and non-prescribed frequency through reference channel -- are appropriately processed in order to generate a signal that has all variations or influences removed therefrom except the temperature variations of the sensing head.
