    Abstract: PURPOSE:To obtain a structure which is superior in water resisting property and wear resistance and is stable electrically, by forming preliminarily an operation face-side electrode on a surface additional film and sticking this electrode to a piezoelectric film or plate to form an ultrasonic transducer structure material. CONSTITUTION:An operation face-side electrode 4' of a high polymer piezoelectric film 3 is formed on a surface additional film 5 consisting of polyester or the like while sticking by the known method, and a metal such as Al, an optional alloy, a conductive paint such as a silver paste, or a metallic foil is used as materials of the electrode. Next, the piezoelectric film 3 is stuck to this electrode 4'. A supporting substrate (acoustic absorber) 1, a rear electrode 2, and the piezoelectric film and the electrode 4' formed on the additional film which are stuck into one body by said method are stuck to a metallic case 6, and a conductor 8 is led out. Thus, the stability, the reliability, and the life of the ultrasonic transducer are improved, and transducers having various structures are produced easily.

    Abstract: PURPOSE:To change over blocks simply and positively by mounting a mechanism, which can freely connect and detach one arbitrary block feeding base to and from automatic block feeding means, to a block housing shelf into which a plurality of block feeding bases are arranged in parallel. CONSTITUTION:When printing by means of blocks installed to block cylinders 1a, 1b is completed, an impression cylinder 3 is separated from a blanket cylinder 2, a paper feeding retractor 24 is also stopped and paper 23 for printing is stopped. Automatic block feeding and discharging devices 20a, 20b are worked, the blocks are removed from the block cylinders 1a, 1b and the blocks are discharged and housed to block discharging bases 16a, 16b through block discharging sections 29a, 29b. When printing is reopened, a block housing shelf 14 is moved up to where a block feeding base 15 housing the block which must be installed to the block cylinder 1a by a command of a controller 40 is connected to a block feeding section 28a, and stopped, and the block is forwarded to the block cylinder 1a by the revolution of feed rollers 17 and installed.

    Abstract: PURPOSE:To allow high efficient type printing of changeable part and printing of fixed part by recording discerning mark for disignation of printing form of each page on printing paper and by reading this mark and selecting a desired print form to print. CONSTITUTION:In a kanji(Chinese character) printer 7 provided with character generation part 3 and print part 4 having reproducing mechanism of magnet tape 2, type printing on a predetermined page and recording of discerning mark for designation of print form to be printed thereafter are made. A printing machine 6 for printing on a printing paper 5' already typewritten comprises two inking units, 12, 13 a plate roll 14, a blanket roll 15, a pressure roll 16, a reader 22 for reading the discerning mark, automatic supplying mechanism 23 for supplying desired print roll based on reading signal transferred from the reader 22 and roll automatic discharge mechanism 24. Thus, type printing of changeable part onto blank printing paper and printing of fixed part onto printing paper with printed changeable part are made at high efficiently.

    Abstract: PURPOSE:To enable a yarn to be positively trained over a bobbin without changing the tension of the yarn by providing a yarn training guide, a guide path, a support and a drive mechanism for training over the bobbin the yarn wound from a west spool temporarily while the bobbins are interchanged. CONSTITUTION:The rotation of a drive shaft 17 in the direction of arrow R moves a yarn training guide support 13 rightward and swings an end of a stick 14 about a pin 21 so that the moving locus of a guide 16 covers a-d. When the guide 16 reaches point d, the rotation of the shaft 17 is stopped and the stick 14 also moves. The guide 16 further advances to e-g and yarn Y is disengaged from a guide 2 and the upstream side yarn reaches the guide 16 from a guide 1 so that the downstream side yarn is taken up by a spool 4. When the guide 16 reaches h, the upstream side yarn engages a ratchet wheel 9 and is taken up by a empty bobbin 7, a guide 26 and a package. The downstream side yarn is pulled and cut by the ratchet wheel 9 and taken up by the spool 4 so that the yarn training from the spool 4 to the empty bobbin 7 is completed.

    Abstract: PURPOSE:To maintain a certain take-up speed of a yarn to be applied for a west spool or the like without a traverse mechanism by providing a rotary drum having a yarn take-up conical portion, a conveying portion and a reservoir portion of the yarn and a guide for introducing the yarn onto the drum. CONSTITUTION:When a package P applied to a yarn take-up device as a west spool is fully wound up by a yarn, a rotary shaft 5 is driven and then a slide bar 24 is moved rightward to shift a yarn biasing guide 23 rightward. The yarn Y is trained over the guide 23 and guided through a traverse fulcrum guide 22 to travel along a path 9. On the other hand, the yarn between the guide 21 and the guide 23 is shifted from a path Y3 to a path Y4 as the guide 21 is moved, while the yarn is trained over a ratchet wheel 7 of the west spool A and the yarn at the yarn biasing guide side is wound up around a rotary drum of the spool A. The yarn wound around the drum is guided by a guide 10 to be moved to a winding point of a winding portion 2 and taken up by the spool A.

    Abstract: PURPOSE:To prevent the stain of a plate cylinder and a blanket cylinder and the damage of the surface of a lithographic plate by arranging an automatic plate-feeding device, an inking device and an automatic plate-removing device in this order in the direction of the rotation of the plate cylinder in the printer wherein a dry type lithography is used. CONSTITUTION:The plate cylinder 1 and 1' provided with the dry type lithographic plate 2 formed of a flexible substrate removably on the surface thereof are arranged removably on the blanket cylinder 3, while the automatic plate-feeding device 11 or 11', the inking device 5 or 5' and the automatic plate-removing device 12 or 12' are arranged in this order along the direction of the rotation of the plastic cylinder 1, 1'. The automatic plate-feeding device 11 or 11', the inking device 5 or 5' and the automatic plate-removing device 12 or 12' are arranged at angles or alpha, alpha', which are 90 deg. or less, to the center of the blanket cylinder 3, while a impression cylinder 4 is arranged removably on the blanket cylinder 3 through the intermediary of a printing medium 9. By this constitution, the stain by ink of the surface of the blanket cylinder due to the shaking of the lithographic plate after being fed can be prevented.
