Inventor: TAKEYA YUTAKA
IPC: C07C1/00
Filed: 1985-05-27
Abstract: PURPOSE:To obtain a xylene mixture with a high p-xylene content from a precipitate, by adding a penta-halogen substituted antimony to a xylene isomer misture solution containing p-xylene to form an adduct, separating the adduct, and obtaining the precipitate. CONSTITUTION:An antimony derivative expressed by the formula SbX5 (X is halogen) is added to a xylene isomer mixture solution containing p-xylene to form an adduct SbX5-xylene, which is then separated from the mixture solution. Thus, a xylene mixture with a high p-xylene content is obtained from the adduct. The antimony derivative in an amount of >=30mol%, preferably >=40mol% is added to the xylene mixture. The p-xylene is selectively adsorbed on the adduct, and the precipitate is directly sucked under reduced pressure to give the xylene mixture rich in the p-xylene or the precipitate is added to hydrochloric acid, etc. to afford the xylene phase as an oily phase.

Title: Fuel tank
Inventor: ISHIKAWA TAKU
IPC: B60K15/077
Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To prevent a fatigue rupture of a film wall forming a fuel chamber which deforms depending on an amount of a fuel to vary a volume of the fuel chamber by providing a means for retaining an opening of a passage, when an amount of the fuel is decreased, at a position opposite to the opening of the passage connecting the fuel chamber to an outside. SOLUTION: When a fuel is supplied to a fuel impregnating pipe 14 and a nonreturn valve 20 is opened by an oil feeding pressure during feeding the fuel, the fuel flows from an opening 11 into a fuel tank 4 through a fuel communicating pipe 10. At this time, an air chamber 6 of an outer shell tank 1 is released to an atmosphere by a pressure-control valve 8 and the fuel tank 4 as a film wall expands by the oil feeding pressure. Further, when an amount of the fuel is decreased, a projection in an opening 71 of a third vapor passage 72 enters into the opening 11 of the fuel common pipe 10 connected to a lower surface of the fuel tank 4 and is retained. As a result, since a horizontal movement of the opening 11 is regulated in the feel tank 4 and sliding on an inner wall of the fuel tank 4 is inhibited, a deterioration due to sliding of the fuel tank 4 can be prevented.

Title: Hood for car
Inventor: ISOBE HISAAKI
IPC: B60R21/34
Filed: 1982-06-30
Abstract: PURPOSE:To prevent contact of a hood to a chassis when the hood is closed and soften the impact and suppress generation of the accident with the dead and the injured, by the organic linking between a hood hinge link, hood damper, and a hood lock striker. CONSTITUTION:When a collision occurs, a load is transmitted to the ring part 11c of a hood hinge link 11, absorbed by an intermediate body 18 through a hood-side hinge pin. Said hinge link 11 is turned in the direction of arrow (b) around a chassis-side hinge pin 12 by the weight over a prescribed value, because of the presence of the hinge pin 12, and the long lever part 11b of the hood hinge link 11 pushes-up the rear edge part 14a of a hood 14 obliquely upward, revolving the ring part 11c through the peripheral part of the intermediate part. Therefore, the hood 14 performs displacement with its rear edge part 14a set upwardly, retreating obliquely, and the impact energy can be absorbed through the above-mentioned retreat.

Title: Vibration preventing method in case of acceleration of robot
Inventor: FUJIKAWA TAKESHI
IPC: G05B19/416
Filed: 1982-06-29
Abstract: PURPOSE:To prevent vibration, by executing acceleration by the time which is equal to a natural period of a robot driving system, in an accelerating point, and adjusting it suitably to acceleration immediately before attaining to a steady speed, in case when a deviation of a response signal to an object signal is out of an allowable range. CONSTITUTION:A robot is regenerated by an object signal g(t) at a selected accelerating point on a scale track, a response signal m0(t) in that case is measured, and a deviation Z0(t) to g(t) is calculated. A representative natural period t0 of a driving system of the robot is derived from Z0(t). After acceleration, a command signal C1(t) which increases a speed by time constant acceleration of the period t0 and attains to a steady speed V0 is generated. The robot is regenerated by C1(t), and a response signal m1(t) is derived. A deviation Z1(t) of the signal m1(t) to said signal g(t) is calculated, and whether the deviation Z1(t) is within an allowable range or not is decided by time >=t0. In case of being out of the allowable range, the signal m1(t) and C1(t) are time-differentiated, a speed of the time point which passes a little through the operate-forecast natural period t0 is compared, and in accordance with its result, the command signal C1(t) is corrected and is used for regenerating the robot.
