Title: Semiconductor integrated circuit device
Inventor: IWATA KATSUMI
IPC: G09G3/20
Filed: 1985-07-19
Abstract: PURPOSE:To extent the dynamic range of an output MOSTFET by connecting a depletion type MOSFET, which clamps a high voltage for display, to the drain terminal of a driving MOSFET. CONSTITUTION:When a signal D to be outputted is in the low level, a driving MOSFET Q1 is turned on, and the drain output outputted from the FET Q1 goes to the same high level as a power source Vcc, and an output MOSFET Q3 is turned off. When the signal D to be outputted is in the high level, the FET Q1 is turned off. Since a depletion type MOSFET Q2 connected to a high voltage -Vdisp for display having a polarity opposite to that of the supply voltage Vcc is connected to the drain of the FET Q1, the drain terminal has a negative threshold voltage of the FET Q2. As the result, a large-amplitude display output signal is generated in the output of the output FET Q3.

Title: Controller for shift of magnetic head
Inventor: OGAWA TOMIHISA
IPC: G11B5/55
Filed: 1983-08-30
Abstract: PURPOSE:To count assuredly cylinder pulses despite and odd number of target tracks by controlling the cylinder pulse output given from a logical circuit via an FF which is set with the zero cross of a head position signal. CONSTITUTION:An FF12 is set when the zero cross of a head position signal P is detected by a zero cross detecting circuit 10. When a signal T showing an odd or even number of target tracks has an odd number and a high level, the output of an NAND gate 13 is set at 0 only when the set Q output of the FF12 is set at a high level in response to the detection of the zero cross of a cylinder signal obtained by a zero cross detecting circuit 11. Then a cylinder pulse SP is delivered from an NAND gate 16. Therefore, no cylinder pulse is produced until the signal P has a zero cross when the number of tracks shows an odd number. Thus the pulse SP having response to an error zero cross due to a signal S obtained differentiating the signal P is not delivered. As a result, the cylinder pulses are counted accurately even in case the target tracks have an odd number.
