Title: Annular bending method for metallic pipe and device therefor
Inventor: MORI MASANOBU
IPC: B21D17/02
Filed: 1994-11-01
Abstract: PURPOSE: To obtain a working method for easily and effectively controlling the wall thickness of an inner bead to an arbitrary desired thickness by abutting a bead forming tool on the circumferential wall of a metallic pipe while a compressive force is imparted to the pipe in the axial direction. CONSTITUTION: A mandrel 4, 5 is inserted into both sides of a pipe 1 with a prescribed space 6 apart between the tip ends of the mandrels 4, 5. Then, while the pipe 1 is rotated with a compressive force imparted to the pipe 1 in the axial direction, a roll 7 as a bead forming tool is abutted on the outer circumference of the pipe 1. Thus, the circumferential wall of the pipe 1 is deformed continuously without interruption to the inward side of the space 6 between the tip ends of the mandrels 4, 5. The compressive force is continuously imparted to the pipe 1 in the axial direction, from the start to the end of the working of the inner bead 2 by the roll 7 on the circumferential wall of the pipe 1. The ratio of thinning the wall thickness of the bead 2 is improved more with a larger compressive force.

Title: Tapered optical fiber device having variable refractive index coating for correcting waveguide characteristic of basic mode
Inventor: ROLAND PATRICIO ESPINDRA
IPC: G02B6/02
Filed: 1999-09-24
Abstract: PROBLEM TO BE SOLVED: To correct the waveguide characteristic of a basic mode by disposing a tapered optical fiber in the longitudinal direction where a part of light signal is introduced to the outside of the fiber and enclosing the region with a coating acting on a part of the light signal emitted from the optical fiber in order to correct the propagation characteristic. SOLUTION: The tapered region 18 is enclosed by a coating 24 of variable refractive index or variable loss material. The tapered region 18 executes an operation free from loss to guide a portion, where a basic mode M cannot be disregarded, into the coating 24 enclosing the cladding 16 beyond the cladding 16 or to the outer side thereof when light passes the tapered region 18. The reason why such operation is executed lies in that the diameter ODCORE of the core diminishes. Consequently, the boundary of the basic mode M is weakened and, therefore, the basic mold field diameter increases. When the basic mode M spreads to the outer side of the cladding 16, the propagation action of the basic mode M is selectively changed.

Title: Motor servo circuit of recording and reproducing device
Inventor: UEHARA MASAHIRO
IPC: H04N5/765
Filed: 1987-10-28
Abstract: PURPOSE:To eliminate the disturbance of a phase reference signal and to stabilize the revolution of a motor by using an external synchronizing signal in the same way as a recording time before and after as a servo phase reference signal at the time of review and reproduction. CONSTITUTION:At the time of normal reproduction, a video floppy 1 is phase- controlled with an internal synchronizing signal (g) as reference. When a first switching signal (a) is 'high', namely, at the review and recording time, the video floppy 1 is phase-controlled with the external synchronizing signal (e) as reference. Furthermore, an AND circuit 13 outputs the external synchronizing signal (e) only when the first switching signal (a) is 'high'. With resetting SSG11 by the output signal of the AND circuit 13, namely, a reset signal (f), the phase of the external synchronizing signal (e) and the internal synchronizing signal (g) coincide at the reviewing and recording time. Since the external synchronizing signal (e) is always set to the phase reference signal (h) at the reviewing and recording time, the disturbance of the phase reference signal (h) is eliminated at the switching time of review/reproduction and recording modes, and stable rotation can be obtained.

IPC: H05K1/02
Filed: 1990-10-08
Abstract: PURPOSE:To enable a circuit board to cope with the miniaturization and the densification of a circuit so as to make an electric equipment miniature and light weight by a method wherein a resin film is formed on the upside of an insulating substrate other than a part where a wiring is provided, and a conduc tive member or an optical waveguide member is put into a recess surrounded with the resin film. CONSTITUTION:A photosensitive resin 2 is applied onto the surface of an insulating board 1 as thick as 10-100mum. A wiring pattern can be controlled in resistance value by varying the resin film 2 in thickness. The resin film 2 is patterned into a resin film 2a through a mask 3 by photosetting the film 2 through ultraviolet rays exposure. When the unexposed resin 2 is removed by cleaning, recesses 5 are formed on the board 1. Then, a conductive member 6 is put into each of the recesses 5. As the conductive member 6 can be formed as thick as the resin film 2a, a wiring section lessened in electrical resistance can be formed even if the wiring is fine in pitch. When the resin film 2a is removed, a circuit board where only a wiring pattern of conductive member 6 is formed can be obtained. Even if an optical waveguide member is used in place of a conductive member, the same result can be obtained.
