Title: Horizontal jib type tower crane
Inventor: KAWABATA KUNIO
IPC: B66C23/04
Filed: 1994-07-22
Abstract: PURPOSE:To carry out a work in a wide range while avoiding an obstacle within the working radius of a horizontal jib type tower crane by arranging a travelable trolley in a main jib so as to allow a slide jib to extend and retract from and into the main jib in such a condition that the slide jib is confined to the slide jib. CONSTITUTION:When an obstacle is present, a signal indicating an extending and retracting distance of a slide jib 2 corresponding to a turn angle has been previously stored in a drive device for a drum 12. When a swivel unit is rotated so that the slide jib 2 approach the range of the obstacle, a drum 12 is turned in accordance with an indicated value thereof, and the slide jib 2 confining a trolley 3 at its distal end is slid into a main jib 1 so that the overall length is adjusted. Thus, the turning radius of the distal end of the jib can be freely adjusted within a range defined by the length of the slide jib 12. Accordingly, it is possible to efficiently carry out a work while detouring an obstacle around the crane or an entrance limited area.

Title: Optical fiber incidence and exit device
Inventor: HOSOYA HIDEYUKI
IPC: G02B6/28
Filed: 1987-07-31
Abstract: PURPOSE:To contrive the improvement in workability and decrease of a working space and to assure the decrease of transmission loss and the stability of transmission characteristics by specifying the included angle theta of the arc length of a bend part and adding extended bend parts thereto. CONSTITUTION:A 1st member 11, a 2nd member 12 and a required device (light source or photodetector) 13 are provided. The curved bend part L in which an optical fiber F passes is formed of the two members 11, 12 and the included angle theta of the arc length of this bend part L is in the relation theta<180 deg.. Both ends of the optical fiber F emitted from this bend part L are, therefore, slightly curved but are not largely curved as heretofore. The surplus length of the optical fiber F is thereby assured and the work for assuring the working space, etc., is reduced. Since the length in the bend part L of the optical fiber F decreases, the transmission loss is decreased.

Title: Boot for mechanical shaft coupling
Inventor: UKAI MIKIO
IPC: F16D3/16
Filed: 1985-08-31
Abstract: PURPOSE:To improve the durability of crest portions by making the first crest portion of a bellows portion thinner than the other crest portions thereof, and folding up the first crest portion preferentially. CONSTITUTION:The wall thickness of the first crest portion/the average wall thickness of the other crest portions is 0.2 to 1.0. That is, the first crest portion is made thinner by controlling parison at the time of blow moulding to reduce the radius of curvature. Further, a notch groove is formed in the peripheral direction of the first crest portion. Accordingly, when the boot is installed on a joint, only the first crest portion (a) which has the minimum rigidity is folded up and pitches of the second to fifth crest portions hardly charge before and after the boot is installed on the joint, so that the durability of the crest portion is improved.

Abstract: PURPOSE:To cope with the speed-up of a loom by changing the forwarded position of a reed with little change of the retreated position by the selection of the position of an eccentric shaft of a pivoting shaft of a swing link connecting a slay sword to a reed-driving crank. CONSTITUTION:When a crank 9 of a reed-driving apparatus is rotated by protruding a piston rod 15a of a hydraulic cylinder 15 to rotate an arm 13 until contacting with a stopper 17, a swing link 18 is swung to drive a reed 7 back and forth.

Abstract: PURPOSE:To observe the outside view from the inside of an elevator cage as well as to make a trend of excessive high temperature in an elevator shaft preventable by setting up an observation window opposable to a transparent window installed in the elevator shaft, and installing a ventilator operating according to the detected temperature of a temperature detector in the shaft. CONSTITUTION:A transparent window 4a to be installed in an elevator shaft 4 is opposed to the outside of a house 1, and an observation window 5a of an elevator cage 5 is opposed to this transparent window 4a. When sunlight streams in the shaft 4 by way of the window 4a whereby temperature in the shaft 4 goes up and is reached to the specified value, a temperature detector 7 detects it, generating an output signal. According to this signal, on-off devices 11, 11a turn shielding plates 10, 10a round in the separation direction from openings 9, 9a. Next, hot air in the shaft 4 flows out of the upper opening 9, outside air flows in from the lower opening 9a and thus heat radiation in the shaft 4 is carried out. Then, when temperature in the shaft 4 is lowered to less than the specified value, the shielding plates 10, 10a close both these openings 9, 9a, so that ventilation in the shaft 4 comes to a stop.
