Title: Printing mechanism of printer
Inventor: SATO KIYONARI
IPC: B41J1/54
Filed: 1989-01-30
Abstract: PURPOSE:To achieve steep reduction of moving parts and striking parts in printing by a method wherein a printing mechanism is composed of a group of magnetized types and an electromagnet. CONSTITUTION:A type wheel 2, one of a type group having a type 202 on a surface and a projection 201 on a back is supported on an outer periphery of a substrate 1, and an electromagnet is composed of an iron core 3, a coil 4, and a yoke 5. The substrate 1 and the type wheel 2 are rotated in the A direction and when a required type 202 comes to a printing position, rotation is stopped and they are stopped. If a coil 4 is so electrified that a platen 6 side of the iron core 3 comes to be of a same pole as that of the projection 201 at that time, the projection 201 receives resilivency from the iron core 3 and is moved in the B direction to push the type 202 out. The type 202 pushes a platen 6 via printing paper 7. Ink preliminarily applied on the face of the type 202 is transferred to the printing paper, and a character is printed.

Title: Wavelength dispersion equalizing method and wavelength dispersion equalization system
Inventor: KATO MASAO
IPC: H04B10/2507
Filed: 1997-02-03
Abstract: PROBLEM TO BE SOLVED: To closely perform wavelength dispersion compensation and to obtain the transmission of an optical signal in a high bit rate by detecting wavelength dispersion fluctuation of an optical fiber transmission line and dynamically controlling dispersion compensation quantity according to dispersion fluctuation quantity. SOLUTION: A signal whose wavelength is distorted by wavelength dispersion is inputted to an optical coupler 13 from an input port, and the polarized wave direction of the optical signal is orthogonally crossed with the polarized wave direction of a polarizer 16 by a polarized wave controller 14. After an optical signal is inputted to and amplified by an optical amplifier 12 from the coupler 13, it is propagated through a dispersion-compensating device 11 one time. The optical signal is made incident on a polarized wave controller 15, that is controlled by a computer 17, and has a certain specific polarization direction. There, it is branched into one that is directed toward an output port again through the coupler 13, and the other that is directed toward the amplifier 12 once more. Because the output port is provided with the polarizer 16, only light that has a specific polarized wave state can permeate it. Therefore, a signal is selectively taken out by controlling the controller 15.

Title: Manufacture of optical connector
Inventor: WATANABE NOBUHIKO
IPC: G02B6/36
Filed: 1984-02-07
Abstract: PURPOSE:To constitute the titled connection so that a bridge reaction of a thermosetting resin of the inside does not advance by cooling a punch at the time of forming, and no influence is exerted on a fiber strand even if a jacket contracts by cooling, by making a gap between the jacket and the fiber strand larger. CONSTITUTION:A die 30A is heated to about 165 deg.C, but a punch 30B is cooled to about 60 deg.C, for instance, by a water-cooled pipe 4, etc., and a transfer forming is executed. As a result, a thermosetting resin 42 in the die 30A is bridged and hardened, but the thermosetting resin 42 in the punch 30B is left in an unhardened state. Subsequently, in its state, a core 20 is fetched by opening a metallic die, and thereafter, a read end part 26 left in an unbridged state is heated and bridged over again. As for the core 20 formed in this way, a gap 18 between a jacket 12 and a fiber strand 14 becomes large. Even if the jacket 12 contracts in a low temperature area, no influence is exerted on the fiber strand 14, therefore, a transmission loss does not increase either.

Abstract: PURPOSE:To reduce wearing, vibration, noise, etc., to improve durability and further to miniaturize an intermediate guide [art of a chain link and the column end part, in a device. CONSTITUTION:Since each guide roller of guide roller train of small diameter, set up along circular arc-shaped moving path (guide roller support) 8 to 11 of fixed radius of curvature, is brought into contact with one side of a bucket chain link, to change a direction of a chain 1 by rolling contact of each guide roller, an impact generated at the time of meshing relating to a sprocket is eliminated, to prevent generating vibration and noise.
