Title: Magnetic recording and reproducing device
Inventor: KATSUMARU IKUKO
IPC: G11B21/08
Filed: 1990-03-28
Abstract: PURPOSE:To always confirm the position of a magnetic head and to enable the high speed seek by detecting the timing for the magnetic head to traverse a track based on the level of a signal to be read out from the magnetic head. CONSTITUTION:When a data on a recording medium is read out by the head 11, an output signal S1 is outputted from an R/W amplifier 12, and by comparing the signal S1 with a prescribed voltage level by a comparator 14, a signal S2 of L at the time of positioning the head 11 in an erase area 21 is obtained. A prescribed pulse signal S3 is outputted on the rise of the signal S2 by a data converter 15. By this method, the pulse signal S3 is outputted at the timing of traversing a track by the head 11. The pulse signal S3 is counted by a CPU 17 to calculated the present position of the head 11. Then, the present moving speed of the head 11 is also calculated by the CPU 17 by dividing a time interval of the signal S3 by a pitch between the tracks. The head is moved to a target track via a VCM 20 by the CPU 17 based on the calculated present position and moving speed.

Title: Semiconductor integrated circuit
Inventor: HANAMURA KOUICHI
IPC: G11C5/00
Filed: 1981-05-25
Abstract: PURPOSE:To electrically discriminate on ROM of a semiconductor integrated circuit and then to automate various processing, by adding an instruction for outputting information on the discrimination of an incorporated ROM. CONSTITUTION:When an instruction code inputted from the outside through an input and output interface 5, the instruction is decoded by an instruction decoder 7 generally through an instruction register 6. An instruction for outputting discrimination information, on the other hand, is decoded by the instruction decoder which corresponds to an empty address 8 to output a signal to a control circuit part 9. By this signal, the control circuit part outputs the discrimination information. Further, the same effect is obtained by adding a control pit for indicating the output of the discrimination information to even an ROM-incorporated semiconductor circuit other than a one-chip microcomputer.

Filed: 1981-05-27
Abstract: PURPOSE:To prevent influence exerted on an exposure control operation by a bias current from a comparator for deciding a luminance level, by setting said comparator to an inactive state when controlling an exposure. CONSTITUTION:A comparator 14 decides a luminance level by detecting a charging current of a time constant capacitor 6 of an exposure controlling circuit. When controlling an exposure, a transistor 15 is turned on by a control signal from a controlling circuit 18, and the comparator 14 is held at an inactivated state. As a result, it is prevented that a current flows out from an input terminal of the comparator 14. In this way, it is possible to prevent influence exerted on an exposure control operation by a bias current from the comparator 14, by setting the comparator 14 for deciding the luminance level to an inactivated stat, when controlling the exposure.

Abstract: PURPOSE:To contrive the improvement of information maintenance and write- erasure performance by a method wherein the charge accumulation part using an SiO2 film and an Si3N4 film and the charge accumulation part using a floating gate are provided on a channel region, and these are used as a memory. CONSTITUTION:The Si3N4 film 6 and the floating gate 9 are formed between a drain 2 and a source 3 via the tunnel SiO2 film 7, and a control gate electrode 8 is formed above it via the SiO2 film 4. There are two ways to perform write into this element: one is the method wherein electrons are trapped in the neighborhood of the boundary surface between the SiO2 film 7 and the Si3N4 film 6 by impressing a voltage between the electrode 8 and a substrate 1, and the other is the method wherein the floating gate 9 is electrified by impressing a positive voltage on the gate electrode 8 and the drain 2. When charges exist between the SiO2 film 7 and the Si3N4 film 6, erasure is performed by impressing a positive voltage on the substrate 1 and earthing the electrode 8. On the other hand, when the charges exist in the gate 9, it is performed by irradiating ultraviolet rays 10. Readout is performed by detecting the variation of the amount of current between the drain 2 and the source 3.
