Title: Gate array
Inventor: SHIRATO TAKEHIDE
IPC: H01L21/82
Filed: 1990-04-18
Abstract: PURPOSE:To provide a gate array with very fine unit cells by filling conducting material in an insulator-coated trench that is formed in source and drain regions of a semiconductor substrate by self-alignment etching so that the layout spacing between the source and drain regions and the substrate contact may become zero on the surface. CONSTITUTION:A trench is self-aligned in p<+> source and drain regions 6. The trench has an insulating film 16 on its side wall and an n<+> region 8 on the bottom, and it is filled with a conductor 17 (selective CVD film). The conductor 17 and the region 8 form a substrate contact. Since no surface layout area is required between the p<+> source and drain regions 6 and the substrate contact (17, 8), the unit cell in this constitution has a very high packing density.

Title: Circuit for negating sync crosstalk
Inventor: SATO SHIGEMI
IPC: G11B5/48
Filed: 1987-04-27
Abstract: PURPOSE:To eliminate the effect of crosstalk and to perform reproduction with fidelity, by providing a dummy recording and reproducing head having the same structure as that of a recording and reproducing head separately, generating a signal having polarity opposite to that of a crosstalk component going round from a recording head part to a reproducing head, and mixing them. CONSTITUTION:When a driving current is permitted to flow on a first recording head part 1a after amplifying a recording signal at a recording amplifier 2, the current also flows on a second recording head part 11a, and a part of the recording signal, that are crosstalk signals eX1 and eX2' leak on first and second reproducing heads 1b and 11b. A reproducing amplifier 12 amplifies crosstalk eY2', however, the polarity of the eY2' is opposite to that of the eX1, and also, it is possible to set the amplitude of the output eY2 of the reproducing amplifier 12 equal to that of the eX1 by adjusting the gain of the reproducing amplifier. Therefore, only the recording signal es is outputted from a mixing circuit 13, and the crosstalk signal is negated, then, no crosstalk signal appears on an output. In such a way, it is possible to obtain a reproducing signal from which the effect of the crosstalk signal is eliminated, and to perform the reproduction of the recording signal with fidelity.

Title: Registering/collating method for personal identification number or the like
Inventor: NAKANO ISATO
IPC: G06Q20/40
Filed: 1987-04-27
Abstract: PURPOSE:To prevent the illegal use of an identification number by recording a number replaced by a prescribed replacement rule on a card. CONSTITUTION:An identification number B(6789) which is replaced with another identification number A(1234) by a prescribed replacement rule (1 6, 2 7, 3 8, 4 9) is recorded on a card 1. A card collator 2 obtains a number (6789) replaced with the number A(1234) from this input number A(1234) and replacement rule information (*) 4. Then the collator 2 reads out the number B(6789) of the card 1 to compare this number with another number (6789) produced from replacement and decides that the user of the card 1 is correct when coincidence is obtained between both numbers. Thus the illegal use of cards is extremely reduced compared with a conventional card storing merely an identification number. As a result, the card reliability is improved.

Abstract: PURPOSE:To enable measurement of a tooth profile or a pitch of a large-side gear by a small-sized apparatus by rotating a displacement sensor under the control of a controller while moving it straight and by making it move to describe a basic involute tooth profile. CONSTITUTION:An X-axis moving mechanism 4 moves a displacement sensor 12 straight in the direction X intersecting perpendicularly a radial line prescribing a pressure angle with a straight line connecting a pitch point on the tooth surface of a gear 51 to be measured and the center of the gear, while the sensor is turned around the center of rotation of the gear by a turning table 3. Under the control of a controller, the sensor 12 is rotated by a minute angle theta by the table 3, while it is moved straight in the direction X intersecting the radial line perpendicularly by the moving mechanism by theta(Dp.cos alpha)1/2 (Dp is the diameter of a pitch circle of the gear and alpha the pressure angle). Thereby a probe 12a of the sensor 12 is so moved in linkage as to describe a basic involute tooth profile. Based on detection signals obtained from the sensor 12 by conducting a plurality of operations of movement in linkage, therefore, measurement is executed and the result thereof is recorded.

Abstract: PROBLEM TO BE SOLVED: To continuously judge a contact check for a fixed period by composing a diagnosis circuit with a comparator for outputting the comparison signal between an input signal and a reference voltage and an AND circuit for outputting the AND signal between the output of the comparator and a control signal. SOLUTION: An output signal A13 of a differential amplifier 13 is connected to a comparator 20 for outputting a comparison signal with a reference voltage 21, and the output is connected to the input terminal of an AND gate 27. The AND gate 27 outputs the AND signal between a control signal EN' and the comparator 20. Therefore, the gate 27 continuously outputs an output signal D20 of the comparator 20 to a CPU 19 as an error signal while the control signal EN' is at a high state. With this kind of configuration, the contact check can be continuously judged for a fixed interval, Therefore, the CPU 19 can securely detect contact failure even if a signal being inputted to a check circuit greatly fluctuates due to the contact failure or the like of a lead wire for measurement.
