Title: Manufacture of polygonal angling rod
Inventor: INOUE TOKIYASU
IPC: A01K87/00
Filed: 1985-07-30
Abstract: PURPOSE:To easily manufacture various polygonal angling rods with different rod diameter and wall thickness at low cost by using the same outer mold by a structure wherein a mandrel is wound with prepreg and further wound with tape to the amount that can fill the gap of the hollow part against the outer form. CONSTITUTION:A mandrel 1 is wound with prepreg 2 by three plies and further wound with tape 3 by the thickness necessary for filling the gap of the holloe part made betweenn the outer peripheral surface of said prepreg and the inner peripheral surface of an outer mold 4 so as to be heated under pressure in the outer mold in order to be cured. After the prepreg is cured, the whole assembly is taken out of the mold by opening the mold and a polygonal angling rod such as hexagonal angling rod or the like is obtained by removing the tape and the mandrel. When the prepreg is wound by two plies and the tape is wound in excess by the amount corresponding to one ply of the prepreg, an angling rod with a smaller rod diameter is obtained by using one and the same outer mold 4. Because one and the same mold is used, the replacement of a mold and the like become unnecessary and consequently rods with various diameters can easily be manufactured at low cost.

Filed: 1988-07-06
Abstract: PURPOSE:To simply and reliably remedy oblique running of a sheet by a method wherein the drive rollers of a slip roller are mounted integrally with a shaft, supporting the drive roller, in a rotation direction and movably in an axial direction and a return means to return the drive roller to a given position is situated to the drive roller. CONSTITUTION:Drive rollers 22a-22c of a slip roller 20 are rotated integrally with a support shaft 21, and a sheet S is brought into abutment with an abutting means 6. In this case, when the sheet S runs obliquely, a thrust force Fs is exerted on the slip roller 20 by means of a rotation force M of the sheet S itself. The drive rollers 22b and 22c are moved along the shaft 21 against a spring 31b according to the thrust force Fs to allow rotation of the sheet S. A thrust force exerted on the drive rollers 22b and 22c along with movement of the drive rollers is reduced, the feed of the sheet on the side where the sheet S does not arrive is performed continuously, and oblique running of the sheet S is remedied. After the sheet S passes the slip roller 20, the roller 20 is returned to its initial position through the force of the spring 31b.

Title: Handling device for booklet
Inventor: WATANABE YOSHIHIRO
IPC: B41J13/26
Filed: 1986-07-18
Abstract: PURPOSE:To enable opening of pages of both longitudinal and lateral types of booklets by means of the same open-page means, by varying the traveling distance of a turning member for opening the page of a booklet according to the stitching direction of the booklet. CONSTITUTION:When a page of a longitudinal booklet P is opened, it can be opened through similar operation to that of a lateral booklet except the method of keeping the booklet with a weight. In other word, a turn roller 33 rotates to the left and a push-up plate 41 pushes up a booklet P' thus starting the turning operation. After turning, the turn roller 33 keeps rotation to the left and compares the situation with that in the case of a lateral booklet so as to allow laying-down of the turning page only after the turn roller 33 advances near to the right end. When the booklet P' is carried to the left and held between the rollers 47a, 47'a, the rollers, 48'a, 49'a, 50'a which keep the turned side with weights are retreated then the turn roller 33 is further advanced to the right so as to lay down the turning page completely and contact tightly, thereafter the booklet P is also carried to the left so as to contact more tightly. Since the traveling distance of the turning member is varied according to the stitching direction of booklet, the page can be turned reliably according to the type of booklet.

Title: Power source for driving hysteresis motor
Inventor: ICHIKAWA KOUSAKU
IPC: H02P5/74
Filed: 1979-12-27
Abstract: PURPOSE:To prevent an overload at the re-start of the motor by a method wherein when a group of hysteresis motors in naturally speed-lowering are started again, the motors are driven at voltages in a range of the voltage less than a rated voltage and more than a counter voltage, reducing the power source voltage for a fixed time.
