Filed: 1980-05-28
Abstract: PURPOSE:To improve the fastness and stability of a sense amplifying circuit, by eliminating influences of back-gate effects by connecting a source terminal to the substrate terminals of FETs forming a differential sense amplifier. CONSTITUTION:A CMOS static differential type sense amplifier consists of N type driving FETs T11 and T12 and P type loading FETs T13 and T14, and input signals I11 and I12 are amplified differentially and outputted from output terminals Q11 and Q12.

Title: Tire air pressure warning device
Inventor: IZUMI KAZUMI
IPC: B60C23/06
Filed: 1993-03-29
Abstract: PURPOSE:To enhance judgement precision by prohibiting the judgement before an undertermined coefficient to be determined on the basis of the initial state of tires is set, in a device judging the abnormalities of air pressure in the tires according to the specified operation expression on the basis of the difference between revolutions of respective tires. CONSTITUTION:Revolution detectors 7 for detecting tire revolutions F1 to F4 are provided to respective front, rear, right and left tires 1 to 4, and the output signals are sent to a controller 11 so as to judge the abnormalities of air pressure in the tires. That is, the mutual tire revolutions of respective sets of the tires 1, 3, and 2, 4 positioned on the diagonal line are separately added to each other, and then the undetermined coefficient Cx is multiplied by F1+F3 and then divided by the value which the average tire revolution is doubled, thereby the deviation value D is found. This deviation value D is compared with the deviation width Ds having the fixed width so as to judge the abnormalities of air pressure in the tires. Since the undetermined coefficient Cx is found by dividing F1+F3 by F2+F4 in drive starting of the vehicle, the judgement of air pressure is prohibited before this undetermined coefficient Cx is set.

Title: Leadframe for outer lead with soldering material
Inventor: HIRAYAMA HIROSHI
IPC: H01L23/50
Filed: 1989-03-24
Abstract: PURPOSE:To enable high precision bonding to a high density and compact ceramic package by fixing tips of a plurality of leads to one another with a soldering material like a narrow tape. CONSTITUTION:Tips of a plurality of leads 10 are fixed to one another with a solder material 16 like a narrow tape. Since the tips of the leads 10 are fixed to one another in one line with the solder material 16 like a narrow tape, the tips of the leads do not move in disorder.

Title: Semiconductor wafer
Inventor: HOSOMI YUTAKA
IPC: H01L21/02
Filed: 1988-03-23
Abstract: PURPOSE:To electrically detect very small cracks difficult to detect with naked eyes or a CCD camera by detecting the presence of conductance or measuring a resistance value between terminals formed at both ends of a conductive layer. CONSTITUTION:A resistance value between terminals 12, 13 at the normal time when no chipped areas or very small cracks occur in a semiconductor wafer 10, is stored in a gauge. When a very small crack 14 which cannot be confirmed with naked eyes or a CCD camera occurs and it cuts a conductive layer 11 completely, the resistance value between the terminals 12, 13 is infinite. When the very small crack 14 cuts only a portion of the conductive layer 11, the resistance value between the terminals 12, 13 takes a predetermined value larger than that at the normal time. Even when the fine crack 14 cuts the conductive layer 11 completely or cuts a portion of it, the resistance value between the terminals 12, 13 varies when the conductive layer 11 surrounding the fine crack 14 is close to or separated from it. By these phenomena, the presence of the very small crack 14 or its degree can be detected.
