Title: Signal reproducing circuit for mr head
Inventor: UMEYAMA TAKEHIKO
IPC: G11B20/10
Filed: 1995-07-24
Abstract: PROBLEM TO BE SOLVED: To suppress a disturbance signal by extracting the disturbance signal from an inputted data signal, generating a switching signal on the basis of the disturbance signal and making the data signal pass through HPF in either H level mode or L level mode by the switching signal. SOLUTION: When a part on which a disturbance signal is superimposed, is inputted, a data signal exceeds a comparison voltage of a constant voltage source 17 by the disturbance signal and so, an output of a comparator 12 rises from at a first level to at a second level. The voltage level of the disturbance signal falls with the passage of time and the data signal becomes lower than the comparison voltage V1h1 of the voltage source 17, and the output of the comparator 12 falls from the second level to the first level. When the data signal becomes lower than the comparison voltage V1h1 , a NPN transistor TR12a becomes nonconductive and TR12b become conductive and the collector potential of TR12b is changed from a 1st to 2nd level transition, and a signal is outputted from the comparator 12.  Thus, it is possible to suppress the disturbance superimposed on a reading data by a simple circuit constitution.

Title: Solid-state image pickup device
Inventor: IIDA YOSHINORI
IPC: H04N5/335
Filed: 1985-08-28
Abstract: PURPOSE:To largely reduce a smear by forming an irregular shape on a picture element separating region. CONSTITUTION:If an insulating layer 8 is etched by isotropic etching, Si residue 15 is lifted off in the midway of etching, and an irregular shape remains on a picture element separating region 12-1 in the shape that the Si residue is removed. Infrared light which is not absorbed by a photoconductive film 10 of incident light is reflected at random by the irregular shape of the boundary between the layer 8 and the film 10 in the region 12-1 to reduce the leakage light to the layer 8 side. Accordingly, carrier generated due to the leakage light in a semiconductor substrate 1 is reduced. Thus, a smear due to the leakage light from the picture element separating region is largely decreased.
