IPC: H01R4/38
Filed: 1989-03-27
Abstract: PURPOSE: To provide a device for connecting a conductor inserted from upward in a simple structure by providing a protrusion for the nut piece of a screw unit on one of each other opposing sides and providing an undercut acceptor accesible from upward at the leg of a U-shaped member. CONSTITUTION: The legs of a U-shaped washer 6 are engaged with the cutouts 5 on both sides of the each other opposing free ends of a barrel spring (a wire protecting material) 5 from upward to prevent the rotational movement of the leg of the spring 4 for supporting the head of a screw 2. A conductor to be connected is put into a U-shaped member 1 from upward. An undercut acceptor 8a directed to the upper edge of the leg and an acceptor 8b are provided on both sides of the member 1 and at the side edge of the leg, respectively, and protrusions 7a, 7b on both sides of a nut are inserted therein from upward and somewhat shifted to the side. At this time, two shoulders 9 of the spring 4 are put in contact with the side edge of the U-shaped member 1, so that the protrusions 7a, 7b can be removed therefrom only by somewhat turning the screw 2 from the undercut area of the acceptor.  The shoulders 9 serve as locking operation and as a position fixing member for a connecting device when the conductor is pulled after the conductor is connected.

Title: Semiconductor integrated circuit
Inventor: MATSUURA HIDEKI
IPC: H01L21/66
Filed: 1989-03-24
Abstract: PURPOSE:To prevent the decline of yield at the time of wafer test by rapidly finding out the abnormality of the pins of a probe card, the inclination of the probe card, and the failure in determination of over-drive quantity by arranging a pair of exclusive pads for measuring a contact resistance between the tip of the probe card pins and the pads. CONSTITUTION:In the water test, at first, before a function test of a chip, a constant current is conducted from a pad 6 to a pad 7 and a voltage between the pads 6 and 7 at this time is measured, then the resistance between the pads 6 and 7 is worked out from that voltage value and the applied current value. Similarly, the resistance between the pads 8-9,..., 20-21 are worked out. Then, the test programm is so made that the function test is firstly performed if those resistance are under the predetermined value. Also, an IC tester is previously set to stop when a few chips are regarded as defects continuously by this test. Thus, the abnormality of the tip of the probe card or the determination failure of an over-drive quantity can be found out rapidly, and accordingly the decline in yield at the wafer test can be prevented.

Abstract: PURPOSE:To prevent the failure that conductive wiring patterns flow and those are in contact with each other at the time of resin sealing by electrically connecting leads with a semiconductor element (chip) through a film-form insulator on which a conductive wiring pattern is formed. CONSTITUTION:This device is composed of a film-form insulator (frame) 1, a conductive wiring pattern 2, leads 3, a semiconductor element 4, an electrode (on a chip) and a sealing resin 6.

Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To improve a product yield by setting a target value of a roll interval of a work roll so as to have the distribution of the target value more at a width end side than at a width center side and changing an actual roll interval to conform to the target value in horizontal rolling after a width end face shape is worked to a recessed face. SOLUTION: Both side tapered roll 2DT having tapered off parts 9 to both end parts in the barrel longitudinal direction is adopted for a work roll 2W in horizontal rolling, a tapered work roll 2W corresponding to a target roll interval is selected and used. But, concerning a horizontal pass by the same mills like at 1st pass and a 3rd pass, a 4th pass and a 6th pass, as equipment cost is high in changing to a roll of a shape conforming to an individual target roll interval at each time, an average value of the target roll interval is used for a target value. A tapered shape can be approximated to a linear line or a simple curved line represented in a power series, etc., of a width direction position without any practical problem.
