Title: Method and device for cutting optical fiber
Inventor: SUZUKI ISAO
IPC: G02B6/00
Filed: 1991-07-23
Abstract: PURPOSE:To eliminate such problems that the fiber is not ruptured even when residual compressive stress is present on the fiber surface and that a complete mirror surface shape is not formed even after rupture like a Ti-doped fiber. CONSTITUTION:When the optical fiber 14 is cut, a fine flaw is made in the surface and then tensile stress is applied to the part to rupture the optical fiber. The residual compressive stress of the optical fiber 14 is removed by a heat treatment before a process wherein the flaw is made. Further, a couple of electrodes 30 which faces each other across the optical fiber 14 are added to the optical fiber cutting device equipped with a cutting edge 22 which gives the fine flaw to the optical fiber 14 and a pressing member 24 which bends and breaks the optical fiber to enable the heat treatment. The electrodes move in a (y) direction.

IPC: H01L21/60
Filed: 1984-10-03
Abstract: PURPOSE:To obtain economical surface coats which are suitable for the wire bonding with bonding Al fine wires by a method wherein at least inner lead end surface to be wire-bonded is coated with an Ni-Zn alloy containing a specific percent of Zn. CONSTITUTION:The surface of a lead frame base 10 of Cu alloy is coated with an Ni-Zn alloy. The Zn content of this alloy is 10-90wt%. Electric plating is preferable for its coating method, but a method such as chemical plating, evaporation, or mechanical cladding can be used. The coating is carried out at least at the inner lead end but can be carried out also on the other part of the lead frame, e.g. whole of one surface or both surfaces. After molding to the lead frame, the inner lead ends 5 and the tab 1 are partly provided with an Ni-Zn alloy coat layer 11, and electrode pads 4 on a chip 2 die-bonded with a metallic solder 3 are bonded to the inner lead ends 5 with wire bonding fine wires 6. The Zn content of the Ni-Zn alloy or less than 10wt% of more than 90wt% both reduce the bonding strength.

Title: Foreign matter removal device in semiconductor assembling device
Inventor: TAKANO TADASHI
IPC: H01L23/50
Filed: 1990-08-06
Abstract: PURPOSE:To reduce the lowering of the yield caused by foreign matter by irradiating junction surfaces of electrodes and leads, etc., with focused light from optical generator means to heat, burn, and remove the foreign matter such as dust existent on the junction surfaces. CONSTITUTION:Laser light 7 emitted from a laser light output part 1 is scanned in X and Y directions following a previously stored program, whereby objects to be irradiated on an IC chip 4 such as a pad 5 or a lead 2 are irradiated with the laser light to heat and burn foreign matter 9a existent on a junction surface 8. The burned foreign matter 9b is attracted and removed by an air nozzle 6. The laser used here is a CO2 laser and hence reflectivity of the junction surface on which an electrode part is disposed is higher while reflectivity to foreign matter is lower. Accordingly, the laser light 7 is absorbed only by the foreign matter which is then heated with less affection to the junction surface 8.

Title: Circuit for stabilizing horizontal synchronized signal included in reproduced and modified composite video signal
Inventor: SHIYUDO KATSUYUKI
IPC: H04N5/93
Filed: 1986-09-03
Abstract: PURPOSE:To prevent signal processing from malfunction even if a reproduced horizontal synchronizng signal is omitted due to some causes by producing a signal in which reproduced horizontal synchronizing signals continue during continuous vertical scan periods and satisfactorily generating a discontinuous reproduced horizontal synchronizing signal included in a modified composite video signal. CONSTITUTION:A noise removal circuit NEC consists of three monostable multivibrators MM1-MM3. The monostable multivibrator MM1 outputs an output signal P1 with a narrow pulse width from a leading edge position in terms of an input signal and gives it to an AND circuit A1. The MM2 outputs an output signal with a pulse width slightly shorter than one horizontal scan period in the leading edge position in terms of the input signal, and triggers the MM3 by the fall of said signal. The monostable multivibrator MM3 outputs an output signal P2 with a comparatively short width including the leading edge position of the reproduced horizontal synchronizing signal Phr, and gives it as a gate signal to the AND circuit A1. It outputs an output signal P3 in the time position of the reproduced synchronizing signal Phr a part from the time positions of the omitted reproduced synchronizing signal and its next one, thereby removing noise.
