Title: Driving device for four-wheel derive vehicle
Inventor: KOTAKE NOBUYUKI
IPC: B60K17/34
Filed: 1986-04-28
Abstract: PURPOSE:To prevent an excessive force from being applied to front and rear wheel transmission systems by providing a buffer means permitting the occurrence of rotary phase difference between both transmission systems on one of them. CONSTITUTION:When a swing arm is vertically moved, rear wheels 50 are rotated relatively to it. This rotation is transmitted to front wheels 36 via a rear wheel transmission system A and a front wheel transmission system B. If an excessive force is applied to both transmission systems A, B, the cam face 70f of a cylindrical cam 70g rides on a cam face 70e, the cylindrical cam 70g is moved to the right while compressing a spring 70h, and a rotary phase difference is generated between both transmission systems A, B. As a result, an excessive force is never applied to both transmission systems A, B. Accordingly, these transmission systems A, B can be made lightweight.

Filed: 1989-04-17
Abstract: PURPOSE:To reduce a surge pressure causing generation of noise by providing a supply side flow path supplying from one chamber in a reservoir tank main unit to a control valve operating fluid then returned to the other chamber and a return side flow path returning from the other chamber to the one chamber the operating fluid cooled. CONSTITUTION:A reservoir tank main unit R is partitioned by a partitioning plate 12 into a main chamber 13 and a subchamber 14, connecting a suction port 16 of the main chamber 13 to a return port 19 of the subchamber 14 by a supply side flow path 22 and a feed port 18 of the subchamber 14 to a recirculating port 17 of the main chamber 13 by a return side flow path 23. Operating oil in the main chamber 13 is fed to a control valve 21 by a pump 20, and the operating oil, increasing its temperature, is cooled during the flow in the return side flow path 23, returned to the main chamber 13 and again fed to the control valve 21 by the pump 20. Since the operating fluid can be directly returned to the reservoir tank main unit R, a surge pressure in an outlet side of the control valve 21 can be low suppressed, thus generation of noise can be prevented.

Title: Distance measuring device
Inventor: YASUO HIROYUKI
IPC: G01S7/48
Filed: 1993-03-30
Abstract: PURPOSE:To accurately detect a pulse time difference without the influence of a delay time to improve the accuracy of distance measurement by detecting a feed light which is made to partially branch by a prism and attenuated and a condensed return light through the same light receiving element. CONSTITUTION:The beam of a laser 1 throttled into a proper fineness is wholly reflected by a prism 12 to turn its light path as much as 90 degrees, and is further reflected by a prism 13, and mostly passes through a transmitting and receiving lens 14 to turn into a strongly luminous parallel beam, and is applied to an objective body 4, and irregularly reflects on the surface of the body 4, and its extremely small part returns into the same light path, and is ordinarily projected to a light receiving element 8 as extremely feeble light. When the beam is reflected by the prism 13, the extremely small part of light is projected to the element 8 as an attenuated scattering light. The two lights entering the element 8 are amplified 15 after photoelectric transfer, and transfered into a fixed rectangular wave, and its going and returning time is measured 17 from a time difference between the two pulses. Since sufficiently attenuated feed and return lights are projected to the same element 8, the time difference between the pulses can be accurately obtained, and moreover a delay time becomes equal.

Abstract: PURPOSE:To attain highly reliable control with a simple circuit and to improve the efficiency of expansion, by providing each circuit block of an electronic exchange with a light emitter and a photodetector and connecting these units with an optical cable to control a common bus. CONSTITUTION:The light emitter 1 and photodetector 3 in each block are connected to the optical cable PC through a directional coupler 2, and since the optical cable PC connects all circuit blocks B1-Bn, light from an optional light emitter 1 can be detected by all blocks. When requesting a signal output to a common bus A, the block B2 checks the existence of light in the cable PC within the time t2 assigned to the block B2 itself. Only when there is no light, the block B2 sends light to the cable PC before the time t3 of the following block B3. At the time, the block B2 obtains the right of signal output. Other blocks detect the light from the block B2, and during the signal output of the block B2, output no signal. After completing the signal output from the block B2, the light emission from the light emitter 1 is also stopped and after the time of a point tE, the common bus can be requested by respective blocks again.
