Title: Video signal processing circuit
Inventor: SHIBUE SHIGENORI
IPC: H04N9/83
Filed: 1985-06-20
Abstract: PURPOSE:To attain narrow-band transmission of video signal by inserting a part of the low band component of the output of a frequency converting means that corresponds to the high band component of an input video signal, in a low band part neighboring the high band part of the input video signal. CONSTITUTION:A video signal is inputted to an input terminal 1. A carrier wave generating circuit 2 generates a carrier wave for frequency modulation from the horizontal synchronizing signal of the input video signal. The output from the carrier wave generator 2 is inputted to a balanced modulator 3 as a carrier wave, and a modulated video signal which is frequency-modulated is obtained from the output of the modulator 3. The said signal is inputted to an LPF 4 in order to eliminate its high-frequency components. The output signal from the LPF 4 is added to an original video signal inputted to the terminal 1 by an adder 5. The signal thus obtained is attenuated of its component, for instance, higher than fc/2 (fc is the carrier frequency) by an LPF 6. The frequency spectrum after this attenuation is as shown by the figure which means that the video signal is transmitted in a narrow band.

Title: Magnetic recording medium
Inventor: KITADA MASAHIRO
IPC: C09D7/12
Filed: 1988-06-03
Abstract: PURPOSE:To separate perfectly and magnetically the magnetic recording tracks of concentric or herical hard magnetic material and to prevent crosstalk noise due to magnetic leak by filling the spaces between the tracks with superconducting material. CONSTITUTION:A magnetic layer 9 is formed by applying wisker-type magnetic oxide gammaFe2O3 powder with an organic binder on a nonmagnetic substrate 8 such as glass. The concentric magnetic tracks 10 are formed by fine processing technique using photoresist and then the superconducting powder with an organic binder is applied thereon to form a superconducting layer 11. By polishing the superconducting layer, the magnetic recording medium having the tracks 10 separated by the superconducting material 12 is obtained. When the medium is used at the temperature lower than the transition temperature of superconductivity, the superconducting material gives perfect diamagnetism effect to shield almost completely the leaked magnetic field from neighboring tracks. Thus, the crosstalk noise is suppressed to <=1/100 compared to such tracks separated only specially.

Title: Methods for controlling and interrupting input/output
Inventor: KINOSHITA TOSHIYUKI
IPC: G06F13/12
Filed: 1989-05-31
Abstract: PURPOSE:To unnecessitate page fixing processing and to reduce overhead by setting up a lock enabled to be acquired/released from both of an instruction processor (IP) and an I/O processor (IOP) in each real frame. CONSTITUTION:The IOP 220 executes address conversion for each page including an I/O buffer or a channel program specified by a virtual address, acquires the lock of a real frame when the real frame is allocated, or generates an I/O interruption requesting the allocation of the real frame to the IP 220 when the real frame is not allocated. Since the real frame whose lock is already acquired by the IOP 220 is excluded from the page steal of the IP 210, the real frame is page-stolen during the execution of I/O and its allocation is not released even when the real frame is not fixed on the page by the program. Consequently, it is unnecessary to previously executing the page fixing processing of a page including an I/O buffer or a channel program relating to the generation of the I/O and overhead for page fixing can be reduced.

IPC: H01L29/792
Filed: 1989-05-30
Abstract: PURPOSE:To process a floating gate electrode and a selective gate electrode in a self-alignment manner, by forming the thin film for the selective gate electrode after processing the floating gate electrode, forming a region having partially different density through a shadow effect by implanting impurities through oblique-ion-implantation, and performing etching back by isotropic etching. CONSTITUTION:There is a stepped part corresponding to both film thicknesses owing to the processing of a floating gate electrode 3A and a control gate electrode 5A. Ion implantation or thermal diffusion is so performed that ion- implanted arsenic may be doped up to the bottom of the thin film 8 for a selective gate electrode. If ions are implanted at an implantation angle theta to a board 1, a low-density region 8B of arsenic is formed on one side of the lateral walls of the floating gate electrode 3A and the control gate electrode 5A through a shadow effect as ion implantation has directivity. The low-density region 8A of arsenic can be selectively left remaining by anisotropic etching processing as the etching speed is very slow. Accordingly, a selective gate electrode 8A can be processed in a self-alignment manner with the floating gate electrode 3A.
