Title: Magneto-resistance effect head and its production
Inventor: KAWABE TAKASHI
IPC: G11B5/31
Filed: 1994-08-23
Abstract: PURPOSE: To obtain a magneto-resistance effect head having excellent withstand voltage reliability by making the taper angle at the end of the larger spacing of the spacing between a pair of longitudinal bias films in a sensor part and the spacing of a pair of electrode films steeper than the taper angle at the end of the smaller thereof. CONSTITUTION: The spacing between a pair of the FeMn films 106 is 2.5μm and is wider than the spacing 1.5μm of a pair of the Ta films 107 and the distances between the ends of the FeMn films and the ends of the electrode films are 0.5μm on both right and left. The taper angle of the ends of the FeMn films is 70 deg. and is smaller than the taper angle 40 deg. at the ends of the Ta electrode films. Consequently, the thickness of an alumina film 108 as an upper gap is about 80% of the thickness in the flat part even in the part where the throwing power at the ends of the electrode patterns is poor. The withstand voltage between the NiFe films 109 and the Ta films 107 is thus well maintained. Further, the patterns of both of the FeMn films and the Ta electrode films are formable with good accuracy.

Title: Analog tester
Inventor: KIRA EIJI
IPC: G01R31/26
Filed: 1982-11-11
Abstract: PURPOSE:To shorten the measurement time considerably, by storing the final set value of the just preceding measurement and using this set value in the next measurement when the same lot is tested. CONSTITUTION:In the first measurement of one lot, a controller 31 turns a switch 33 to the side of a storage part 321, where an initial set value is stored, to measure the distortion rate. The value of a programmable attenuator 22 at this time is stored in a storage part 322 for the just preceding set value. In the second and following measurements, the switch 33 is turned to the side of said storage part 322, and measured data is converged to a certain set value with about one loop because electric properties of products resemble one another in one lot in these measurements. If measured data is not converged within a certain time because of an defective product, it is judged to be defective, and the initial set value is used in the test of the next product, and thus measurement is performed in the shortest time in any case.

Abstract: PURPOSE:To determine whether a caulked part is good or defective by applying light from an opposite direction to the caulked part of a terminal and also picking up an image of the caulked part, and by measuring an area of the caulked part from the image to compare the measured value with a reference value which has been specified in advance. CONSTITUTION:Light from a pair of light sources 11 is applied from immediately upper in an opposite direction to each caulked part 5 and also an image of each caulked part 5 is picked up by a pair of cameras 13. The image is subjected to image processing 15 under control of a CPU 21 and displayed on a television monitor 20 as a raw image of a terminal 3. Then the image picked by the camera 13 is binarized by a binary processing circuit 17 of the processor 15 wherein an outline image of the terminal is cut and the image is displayed on the monitor 20 as a binary signal image of contrast. After a window of a predetermined area is set in the binary signal image, image signals of a predetermined width or lower which are successive in a horizontal direction are cut, and images in thin lines by reflected light from an outer peripheral top face of the terminal 3 are removed. Then an area of a circular image of the caulked part 5 in the window is measured to be compared with a reference value.

Title: Transfer and separation device in image forming device
Inventor: ITO NOBUYUKI
IPC: G03G21/00
Filed: 1990-07-30
Abstract: PURPOSE:To maintain stable and excellent transfer and separation functions for a long term with extremely simple constitution by narrowing the aperture part, which is opposed to an image carrier, of the shield of a separation charger which encloses the electrostatic charging wire so that it may become smaller as it approaches the image carrier. CONSTITUTION:The shielding plate of the charger 4', which is formed to enclose the electrostatic charging wire, is provided with parts (b), (c) and (d) constituting a U-shaped part and parts (a) and (e) which narrow the aperture part from the ends of the part (b) and (d) on the image carrier side. With such constitution, the voltage between peaks VPP being the AC component of separation bias is adjusted so that the excellent separation function may be achieved when currents flowing into the parts (a) and (e) out of all the discharge discharged from the wire currents are >= 10-20% and >= 60% currents out of all the discharge currents flow into the parts (a)-(e). By setting the constitution of the shielding plate so that the current advancing toward the image carrier can be regulated and deciding the absorption of he current in the shielding plate for stabilizing the discharge, retransfer and faulty separation do not occur and the excellent separation is always stably performed.

Title: Method for detecting failure of wire bonding
Inventor: ENDOU TAKASHI
IPC: H01L21/66
Filed: 1982-11-13
Abstract: PURPOSE:To detect bonding failure while leaving wire to be contacted to pellet by conducting low electric current at the time of connecting wire and pellet thereby disconnecting at the time of discharge of an electric torch. CONSTITUTION:At first, a ball 4a is formed by the discharge of an electric torch 8 at the end of wire 4 of lower end of a capillary 6. Though high current flows in the wire 4, it does not affect a detector 10 because a switch is grounded through a normally closed contact 9b. The capillary 6 is lowered and makes the first bonding, after which the capillary is lowered into the second bonding position. Meanwhile, the switch 9 is connected to a normally opened contact 9c thereby conducting low current from DC power source 13 or 14 through a resistance 11 and an end 7 to the wire, but the current does not flow into the detector 10. If the wire 4 is not connected to a pellet 1, the current flows into the detector 10 and a bonding failure signal 10a is generated. In case of correct bonding, the capillary continues to descend and makes the second bonding, then the wire is cut from its root by a clamper.
