Title: Rotation speed difference sensing type joint
Inventor: OKUBO TAKASHI
IPC: F16D31/02
Filed: 1998-06-29
Abstract: PROBLEM TO BE SOLVED: To transmit comparatively great torque even in a range of small difference in rotation speed, and prevent torque from being quickly increased as the difference in rotation speed is increased. SOLUTION: A rotor fixes the base end parts of a valve member 17 and a relief valve 18. An orifice 20 communicated with an outlet hole 16, is formed at the free end part of the valve member 17. The free end part of the relief valve 18 closes the orifice 20 by means of the elastic force of itself when the pressure of hydraulic oil in the inside of a cylinder hole 10 is found to have been lower than specified valve opening pressure P1, and the aforesaid free end is separated from the valve member 17 so as to let the orifice 20 be opened.  When the pressure exceeds the specified valve opening pressure P1, the free end part of the valve member 17 isolates a space between the outlet hole 16 and the outside by mans of the elastic force of itself and the elastic force of the relief valve 18, when the pressure of hydraulic oil in the inside of the cylinder hole 10 is found to have been lower than relief pressure P2 (>P1), and when the pressure exceeds relief pressure P2 the free end part is separated from the rotor so as to let the outlet hole 16 to be released.

Abstract: PURPOSE:To improve the copying quality by fixing the recording body extracted from the copying part main body so as not to operate it relatively to the original and while the copying part main body is held so that the light receiving part can face with the original, shifting the body relatively to the original. CONSTITUTION:When the end part of a copying paper 28 to extend from an open hole 23 is held down on an original 25 with one side hand, a main body 21 is shifted in an A direction of an arrow on the original 25 with other side hand, the end part of the copying paper 28 is held down on the original 25, and therefore, the copying paper 28 is pulled out from the main body 21. At such a time, the picture information on the original 25 is received by an image sensor 27, amplified by an amplifier 34, sent to a heating body 30, and therefore, the copying paper 28 is colored in accordance with the heating of the heating body 30 and the image of the original 25 is formed on the copying paper 28. Since the end part of the copying paper 28 is held down on the original 25, the relative shifting quantity to the original 25 of the main body 21 is completely coincident with the length in which the copying paper 28 is pulled out from the main body 21. Thus, the disturbance of the copied picture is eliminated.

IPC: B65H1/26
Filed: 1981-12-10
Abstract: PURPOSE:To prevent a paper detector from being erroneously operated due to paper  dust, by providing such an arrangement that electrical contacts are actuated by an  operating member when a sensing member which follows up the movement of a recording paper does not sense a recording paper but the sensing member is retracted from a  paper feed bed when no paper feed cassette is inserted. CONSTITUTION:When no paper feed cassette A is loaded on a paper feed bed 1, a  sensing member 4 is raised for the insertion of the cassette A. A cam surface (a)  pushes a pin 14 when the cassette A is inserted, and the sensing member 4 rotates  around a shaft 10 as the center while the actuating elements 9A, 9B of a microswitch  8 rotate. At the same time, the sensing member 4 and an actuating member 7 rotate  around a supporting shaft 6 as the center so that the front end 4b of the sensing  member 4 comes into contact with a recording paper X in the paper feed cassette A.  Then, the contacts of the switch 8 are opened to issue a present signal. Next, the actuating element 9A of the switch 8 is pushed back by the actuating edge 7a of the  actuating element 7 when the recording papers (a') run out, so that the contacts are  closed to issue an absent signal. Thereby, no erroneous operation due to paper dust is  brought about and substantially no maintenance and management are required.

Abstract: PROBLEM TO BE SOLVED: To magnify a working region and improve operating efficiency as the excavation of an oblique pit at the time of excavation works by bringing a front linkage to a rockable state in the horizontal direction to the longitudinal direction of a revolving super structure. SOLUTION: The front linkage is applied to a hydraulic backhoe, and an angle control lever is controlled remotely in rocking operation in the horizontal direction of a boom 10. The quantity of a hydraulic cylinder 4 expanded and contracted is adjusted by regulating the flow rate of the pressure oil of a solenoid valve by controlling the solenoid valve by a valve controller at that time. Consequently, the location of rocking in the horizontal direction of the boom 10 can be operated, and all operation of the hydraulic backhoe is controlled remotely. As a result, a cab is unnecessitated, and the rocking range of the boom 10 is magnified up to the whole expansion-contraction limit range of the hydraulic cylinder 4.  Accordingly, since the boom 10 has structure, in which the boom 10 is rocked in the horizontal direction to the longitudinal direction of a revolving super structure 2, an oblique pit can be excavated as a car is left as it is brought to a horizontal state.
