Title: Test head for circuit board inspection apparatus
Inventor: SAIDA KATSUTOSHI
IPC: G01R31/28
Filed: 1998-09-01
Abstract: PROBLEM TO BE SOLVED: To improve a high frequency measuring performance from a prior art. SOLUTION: A receiving pin wire (single wire) 3 is connected to a base end side of each contact pin 1. This wire 3 is extended from a reinforcing block 4B side of a block 4 upward. Trunk boards 6 are stood corresponding to arrays of the pins 1 on the block 4B. The each board 6 is constituted that the one end 5b of each coaxial cable 5 connected at the other end 5a to a wiring pad 20 of an inspection board 2 is electrically connected to the one end 3b of the corresponding single wire 3. Accordingly, since a coupling part of the wire 3 becomes only a short part between a base end 1b of the pin 1 and the board 6, a high frequency transmission performance can be improved as compared with the case of coupling the entirety by the single wire.

IPC: H05K7/14
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To install a fixing mechanism necessary for insertion and pulling out of a printed wiring board, etc., to in and out from the housing frame of a package. SOLUTION: When a printed wiring board 3 is pulled out of a housing frame 2, the sliding part 1e of the lower front plate comes up sliding on the sliding surface 2b of the lower sliding surface of the housing frame, when the lower part of the front plate 1 is pushed, and the front plate is pushed up. At the same time, the sliding part 1d of the upper front plate comes up, sliding on the upper sliding surface 2a of the housing frame. As a result, the front plate is separated towards the direction of the curved arrow from the housing frame. Then, when the front plate is pulled to the right, the printed wiring board is pulled out of the housing frame by the engagement between the front plate- supporting pin 1b and the upper-supporting pin guide hole 3a, and the engagement of the movable front plate-supporting pin 1c and the lower-supporting pin guide hole 3b. When the printed wiring board is inserted into the housing frame, process which is reverse to the above-mentioned operation is conducted.

Title: Magnetoresistance effect type magnetic head
Inventor: TAKINO HIROSHI
IPC: G11B5/39
Filed: 1985-11-05
Abstract: PURPOSE:To surely evade the occurrence of Barkhausen noise by strengthening an external magnetic field in the direction of difficult magnetization of a magnetosensitive part to rotate magnetization from the antiparallel magnetized state and magnetizing both magnetic layers in the same direction by the strong external magnetic field. CONSTITUTION:In a magnetosensitive part 2, magnetic layers 4 and 5 are laminated with a nonmagnetic intermediate layer 3 between them. Thus, magnetic layers 4 and 5 are in magnetized states antiparallel with directions of axes of easy magnetization as shown by arrows M1 and M2 and magnetic barriers do not occur when the external magnetic field is not applied. If an external magnetic field H is strengthened in the direction of difficult magnetization of the magnetosensitive part 2, magnetization is rotated from antiparallel magnetized states in the rotating magnetization stage by the external magnetic field H, and both magnetic layers 4 and 5 are magnetized in the same direction by the stronger external magnetic field. In this case, magnetic barriers do not occur to evade the occurrence of Barkhausen noise.
