Title: Production of helix-type travelling wave tube
Inventor: SHIROKANE MAKOTO
IPC: C04B37/02
Filed: 1987-06-05
Abstract: PURPOSE:To enable the stable increase in the output power of the titled tube, by bonding a helix with a dielectric rod having plural soldering ribbon materials keeping a specific relationship between the width and spacing of the ribbon and the pitch of the helix on the outer circumference of the rod, thereby improving the heat-radiation efficiency of the tube. CONSTITUTION:A plurality of soldering ribbon materials 5 are applied to the outer circumference of a dielectric rod 3 keeping the relationship of W<H<L wherein W is the width of the soldering ribbon material 5, L is the spacing of the ribbon and H is the pitch of helix 2. A helix 2 is inserted into a metal tube 1 via the dielectric rod 3 and heated to bond the helix 2 with the dielectric rod 3 at a part contacting the helix 2 with the dielectric rod 3. A helix-type travelling wave tube can be produced by this process. The heat generated from the helix 2 can be effectively dissipated through the dielectric rod 3 and the metal tube 1 to enable the stable increase in the output power or reduction of size of a helix-type travelling wave tube.

Title: Blancket drum idling device for lithographic correcting machine
Inventor: KOBAYASHI HIDEKAZU
IPC: B41F3/20
Filed: 1978-11-13
Abstract: PURPOSE: To simplify structure and to improve productivity by providing a blancket drum idling device and a fixed-position stopper on one side of a base directly below the gears at the ends of a blancket drum in the stand stoppage position and providing, on the other side of the base, a rack with a notch for enabling the gears to rotate.

Title: Tension servo device
Inventor: SASAKI KENJI
IPC: G11B15/43
Filed: 1988-06-07
Abstract: PURPOSE:To constitute the title device so that tension of a magnetic tape wound by a prescribed limiter is kept constant by providing a tension arm which is coupled selectively with an end part of a band brake, and a band driving member by which the end part of the band brake is fixed or made movable. CONSTITUTION:At the time of reverse reproducing, an end part 29a of a band brake 29 is in a control cam part 42a of a band driving member 40, therefore, its motion is controlled, and an end part 29b is not only formed as one body with a notch part 27b of a tension arm 27 but also in a non-control cam part 43b of the band driving member 40, therefore, its motion is free. As for driving force of a driving motor, a prescribed torque is transferred to a supply reel base 16, and a magnetic tape 1 is wound to a supply reel without being loosened. Also, since the band brake 29 is wound to the supply reel base 16, the torque which is effective for winding the magnetic tape 1 decreases by a portion of a damping load of the band brake 29. In such a way, a variation of tension of the magnetic tape can be suppressed.

Filed: 1983-07-30
Abstract: PURPOSE:To increase the reliability and to reduce the cost for a magnetic head containing a ferromagnetic thin metallic film formed on a junction surface of paired magnetic core halves, by tilting both the magnetic gap forming surface and the thin metallic film forming surface at desired angles. CONSTITUTION:Grooves 21a1-21a3- are formed with V-shaped sections on a ferrite substrate 21. Then oxide glass 22 of a high melting point is filled into those grooves and polished to obtain a plane. While grooves 21b1-21b3- are formed with V-shaped sections at the areas where no glass 22 is filled. Thin metallic films 23 are laminated via insulated films of high hardness and polished into a plane to obtain core half blocks 31a and 31b. The block 31a contains a winding groove 25 and a glass groove 26 and is butted to the other block 31b. Then a glass rod is put into the groove 26 and fused, and the fused glass is filled into the hollow parts on the surface of the film 23. Then both blocks are put together. This combined block is sliced to cut the groove 26 and then polished. Thus it is possible to obtain a magnetic head having high reliability and containing a magnetic gap (g) tilted in the lamination direction of the film 23.

Title: Electrostatic induction type digitizer
Inventor: NAGAYAMA TADAHIRO
IPC: G06F3/03
Filed: 1985-06-28
Abstract: PURPOSE:To reduce an error caused by an influence of a hand without thickening an insulating sheet, by placing the second resistance film through the insulating sheet on the rear side of the first resistance film, and also grounding this second resistance film. CONSTITUTION:A resistance film 1 and 24 are placed on both faces of an insulating sheet 23, respectively, and the film 24 is grounded through a low resistance film 25. The film 1 and 24 are coupled electrostatically and a part of a current flowing through the film 1 is diverted ot the film 24. Therefore, a virtual resistance of the film 1 decreases, a coupling impedance of a hand on the film 1 and the film 1 drops relatively, and a disorder of the potential distribution on the film 1 decreases. Also, since the film 24 is grounded, the film 1 is grounded through the coupling impedance between the films, and the potential to the ground of the film 1 is stabilized. Therefore, even if the human body has the ground potential, a voltage difference between the film 1 and a hand decreases, a current flowing to othe ground through the hand from the film 1 decreases, and adisorder of the potential distribution of the film 1 decreases. Accordingly, a coordinate detecting error generated by an influence of the hand is reduced.
