IPC: G01B21/00
Filed: 1980-12-05
Abstract: PURPOSE:To obtain a simple and compact position detector by constituting the same so that the position of a movable member whose sphere of movement is fixed is detected by a single displacement member which makes displacement in connection with the movable member and by a single position detector. CONSTITUTION:A disc-shaped body 4 fixed to a rotating shaft 3 rotating in connection with the motion of the movable member 2 such as a robot arm and a gap sensor 5 are arranged. The disc-shaped body 4 is provided with four circular-arc parts 61-64 formed in such a manner that the radiuses r1-r4 become larger sequentially in the range of angles theta1-theta4 and these circular-arc parts are connected by straight parts 612-641 betwee them. When the disc-shaped body 4 rotates to make the straight part 612 opposed to the sensor 5, the output of the sensor 5 turns minimum, whereby the displacement of the movable member 2 to one limiting position is detected. In addition, by the straight part 634 the other limiting position is detected. By this constitution, the simple and compact position detector is obtained.

Abstract: PURPOSE:To reduce the sizes of a case and an engine by a method wherein the case of a trochoidal pump is mounted to the end surface of an engine block and a bowl-shaped pulley is mounted on a drive shaft in a manner to cover the case and caused to approach the engine block. CONSTITUTION:With an engine run, an inner gear 2 is rotated through a timing belt 11 and a pulley 10 by means of a drive shaft 4. In which case, an outer gear 2 follows an outer gear 3 for rotation, a pump action is effected through the change in volume of the outer gear 3, and lubricating oil is fed with a pressure to each part of the engine. In this case, the flow of lubricating oil leaking along the drive shaft 4 is stopped by an oil seal 5, and the lubricating oil flows through a lateral hole 7 and a core hole 6 of the drive shaft 4 to the interior of an engine block 8.

Title: Method of preserving plastic film roll
Inventor: OTAKI TOSHIHIRO
IPC: B65H19/12
Filed: 1986-07-23
Abstract: PURPOSE:To prevent deformation of and wrinkling in a film roll 11 during a long term storage, by preserving a plastic roll which has been wound up at a predetermined void ratio while it is rotated in a predetermined range of rotational speed. CONSTITUTION:The rotational speed of a plastic film roll 11 which has been wound up on a wind-up shaft at a predetermined void ratio of 0.6 to 0.95 is set in a range of 5 to 1000 revolutions/hour, preferably 50 to 300 revolutions/hour. When the roll 11 is rotated at a relatively low speed as such during preservation of the plastic roll 11, the acting direction of the force F due to the dead weight of the film changes every moment while the roll 11 is rotated in a uniform direction, and therefore, the force F successively acts upon uniformly over the entire periphery of the roll 11 in the circumferential direction so that no force in a specific direction, which deforms the wound film layers into an elliptic shape, is effected thereby it is possible to prevent deformation. Further, the force F acting upon a part of the wound film layers below the wind-up shaft 12, is effected in a direction reverse to the looseness take-up direction of the roll 11, and more-over acts upon the circumferential direction of the roll 11, successively, so that the looseness take-up of the entire roll 11 is restrained, thereby it is possible to prevent distortion of and wrinkling in the roll 11.

At the same time, the luminance signal of a prescribed frequency is delivered from the band pass filter 13 using a comb-shaped filter. The outputs of the filters 9 and 16 are applied to the level expanders 10 and 14 respectively with te level expansion property given. Thus the carrier chrominance signal with the cross-color disturbance eliminated is delivered from the output terminal 11 of the expander 10. The output of the expander 14 is applid to the adder 15 to be added by the output of the band blocking filter 12. Thus the carrier chrominance signal of a prescribed frequency is eliminated to deliver the luminance signal.
