Title: Manufacture of prestressed composite member
Inventor: KAWAGUCHI MAMORU
IPC: E04C3/26
Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To prevent cracks from developing owing to the shrinkage by drying or the like, which easily tends to develop at the end parts of a concrete part, by a method wherein a prestressing is introduced in the concrete part of a composite member consisting of a structural steel material and a concrete nearly uniform along its longitudinal direction. SOLUTION: Seat plates are abutted against stoppers fixed to the end parts of a structural steel material 1. The tip parts of bolts passing through the lower end parts of reaction accepting material 2 are screwed in threaded holes provided in the seat plates. The free end parts of the reaction accepting material 2 project by proper lengths to one side of the structural steel material 1 so as to apply a pure bending to the structural steel material 1 by tensing a PC steel material 3 spanned between these free end parts. Under the above- mentioned state, a concrete for constituting the concrete part 7 of a composite member is placed to the tension side of the structural steel material 1.  After the hardening of the concrete, the tensing of the PC steel material 3 is released, resulting in introducing prestressing in the concrete part 7 of the composite member over the whole length of the concrete part.

Title: Liquid drink-containing can
Inventor: OKUBO TAKASHI
IPC: B65D17/28
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To easily ascertain a mouthpiece of a can and facilitate drinking of contents without spilling it by forming a recess in which a lower lip can be put on the outer wall of the can in the vicinity of a seal section where a part to be the mouthpiece of the can is sealed. SOLUTION: In each of a straight type can 1 and a partly tapered can 2, a recess 12 in which a lower lip can be put is formed on the outer face of the can nearest a sealed section 9 where a mouthpiece is sealed. As a result, when the lower lip is being fitted to the center of a recessed curved face, stability is best. When the lower lip is deviated from the center of the recessed curved face, butting of the lower lip is unnatural and the touch impairs. Accordingly, drinking begins after the can is turned and adjusted unconsciously so as to make the lower lip comes to the center of the recessed curved face where the lower lip fits optimally. In view of such an advantage, even the aged, little children, and the blind can easily drink without staining their clothes due to spilling of the contents.

Filed: 1988-03-14
Abstract: PURPOSE:To prevent failure of fusion splicing by bringing an ignition source into contact with a part in the longitudinal direction of an optical fiber in an oxygen atmosphere and burning away the coating material. CONSTITUTION:Removal of the coating of the optical fiber is first executed by holding the optical fiber 5 by holders 4 in a chamber 1 and introducing oxygen from an oxygen supplying part 2 continuously into the chamber 1 to maintain the oxygen atmosphere therein.

Title: Detecting device for mobile body
Inventor: HANABATAKE TOSHIO
IPC: G01S7/52
Filed: 1986-03-17
Abstract: PURPOSE:To detect level variation and to detect whether or not there is a mobile body by detecting the difference in amplitude between two pulses obtained by sampling a reflected wave at constant intervals of time. CONSTITUTION:An oscillator 1 sends an acoustic wave outside the audio frequency range to a body to be detected by using an acoustic wave radiator 2. Its reflected wave is passed through a sound collector 3 and level-adjusted by an automatic gain adjusting amplifier 4. The output of the amplifier 4 is sampled by an A/D converter 5 and the amplitude value at the moment of the sampling becomes a digital value, which is supplied to an amplitude difference detector 6. The detector 6 extracts the difference between two sampled values which succeed in terms of time and supplies the absolute amplitude difference signal to an absolute crest value detector 7. Even if the crest value is negative, the detector 7 inverts it to a positive value and outputs the inverted value. This crest value is held by a crest value holding circuit 8 and supplied to a comparator 9. This crest value is compared 9 and when it exceeds a reference value, a comparison output is generated, thereby detecting the mobile body.

Filed: 1980-05-08
Abstract: PURPOSE:To obtain an even output in the radius direction of a magnetic disk or diskette, by varying the orientation of a magnetic substance on a magnetic recording medium within the same medium. CONSTITUTION:The orientations 29-31 of the magnetic substance of a magnetic disk 1 or diskette 3 are weakened gradually from the most inner circumference  toward the outer circumference. For this purpose, a disk 1 of Al or polyester is attached to a rotary shaft 6, and a magnetic coating material is sprayed from the  outer circumference toward the inner circumference through a nozzle tube 9 that  moves round the shaft 18. Meanwhile the disk 1 turns containuosly and thus a coating having a small thickness at the inner circumference is obtained by the centrifugal force. On the other hand, a coil magnet 20 is moved from the outer to inner circumference on an arm 19. In this case, a contact shoe 21 at the rear end of the arm  19 slides on a arc-shaped winding resistance 8. Thus the resistance value is reduced  gradually, and at the same time the magnetic field becomes strong gradually. In  such way, an even output is obtained in the radius direction of a magnetic disk or  diskette.
