Patent EP-0342787-A3 (EP)
Title: Search method for generating test vectors for sequential logic circuits
IPC: G06F11/25
Filed: 1989-04-06
Abstract: A method for developing a test sequence and for testing manufactured 
digital circuits. Test vectors are developed based on a simulation-based, directed-­
search approach. Specifically, from a given test vector, a next test vector is 
developed by altering the given test vector and determining the utility of the 
altered trial vector in propagating circuit faults to the primary outputs, based on a 
simulation of the circuit and a preselected cost function. The vector set is created 
through an iterative process of altering an accepted test vector to develop a next 
trial vector. The vector set is efficiently developed by employing one phase that 
treats the entire set of circuit faults as the target, followed by another phase that 
targets specific faults that have not been detected in the previous phase.

Title: Comb filter circuit for removing noise
IPC: H04N5/21
Filed: 1990-05-04
Abstract: A comb filter circuit includes a delay circuit (12) 
for delaying an input signal by a predetermined period 
to output a delayed signal. A subtractor (11) calcu­
lates a difference between the input signal and the 
delayed signal output from the delay circuit (12) to 
output a difference signal. A limiter circuit (13) 
limits the difference signal output from the subtractor 
(11) by a limiter level changed in accordance with a 
level of any one of the input signal and the delayed 
signal. A calculator (16, 18) receives the input signal 
and the limit signal from the limiter circuit (13) to 
perform a predetermined calculating operation. A 
noncorrelation detector (19) for detecting a degree 
of noncorrelation between the input signal and the 
delayed signal from the difference signal output from 
the subtracting means (11) at a level changed in 
accordance with a level of any one of the input signal 
and the delayed signal.

Title: Magnetoresistance effect type thin film magnetic head
IPC: G11B5/39
Filed: 1992-09-25
Abstract: The head includes a MR element (1) having the electrical 
resistance changed according to a change in an applied 
signal magnetic field, a lead electrode (2) for detecting 
a voltage change generated across the ends of the MR 
element in which a change in electrical resistance is 
generated, and high coercive force films (11a, 11b) for 
applying a weak magnetic field to the MR element (1). The 
high coercive force films (11a, 11b) are arranged in the 
proximity of the ends of the MR element (1) and at a 
predetermined position between the ends. According to 
this structure, a weak magnetic field is applied in 
uniform over the entire MR element to facilitate 
unification of magnetic domain of the MR element even in 
the case of a long MR element (1). Therefore, unification 
of magnetic domain can easily be carried out over the 
entire region of the MR element without increasing the 
film thickness of the high coercive force film even in the 
case of a wide track width, resulting in a thin film 
magnetic head with no Barkhausen noise generation.

Inventor: TSUJIMOTO AKIRA
IPC: G11C29/00
Filed: 1993-09-29
Abstract: A power supply system (15) incorporated in a dynamic random access memory device distributes a step-down power voltage (Vint) and a boosted voltage (Vboot) to a sense amplifier unit (13a) and a word line driver (12a) for allowing switching transistors of the memory cells to transfer the step-down voltage level to the storage capacitor without any voltage drop in read-out and write-in modes, and the switching transistors and the storage capacitors are subjected to inspections through a burn-in testing process before delivery from the manufacturing factory so as to actualize potential failure; however, either switching transistors or storage capacitors are insufficiently stressed in the burn-in testing process, and the power supply system changes the ratio of the boosted voltage to the step-down power voltage between the read-out and write-in modes and the burn-in testing process so that the switching transistors and the storage capacitors are sufficiently stressed. <IMAGE>
