Title: Priority control system for main memory access in multi-processor system
Inventor: CHIBA TAKASHI
IPC: G06F15/16
Filed: 1986-09-30
Abstract: PURPOSE:To avoid deterioration of the system performance by having the dynamic change of priority for main memory accesses by an access request of a CPU and therefore eliminating the difference of priority among CPU. CONSTITUTION:A priority control circuit P contains a circuit 11 which checks whether an access request held by each port 10 can be started against a main memory or not, a circuit 13 which selects a single piece out of the ON signals 12 based on a flipper bit, and a circuit 15 which selects a single port by means of the signal 14 of the circuit 13. When coincidence of comparison is secured in a valid state of a comparator 19, the access of a main memory is cancelled. In the circuit 11 a port access request is suppressed by an OR logic between a 'BUSY' flag of a bank and a flag holding a cancelled state due to a block. Therefore it is avoided that an access once cancelled never starts the main memory access many times.

Title: Magnetic field sensor
Inventor: KOSHIMOTO YASUHIRO
IPC: G01R33/02
Filed: 1989-09-08
Abstract: PURPOSE:To measure a low frequency magnetic field with a high S/N ratio by periodically applying a current of critical current density or more to the superconductive plate provided in a magnetic shield and selectively amplifying the frequency coinciding with the current frequency of a magnetoelectric converter. CONSTITUTION:A fixed shield 2 and variable shields 3, 4 are provided so as to cover a magnetoelectric converter 1 and the temp. of the shields 3, 4 is set to temp. slightly lower than superconductivity developing temp. and the current flowing to the shields 3, 4 from an AC current source 12 increases and, when the current value of the current exceeds a critical current value, superconductive characteristics break and susceptibility becomes zero and magnetic flux enters a magnetic field sensor. When the current value becomes the critical current value or less, superconductivity is again developed and the magnetic flux is discharged from the magnetic field sensor and the output from the converter 1 becomes one corresponding to a zero magnetic field. Since a low frequency magnetic field is subjected to AM modulation by the frequency of the current source 12, for example, when a magnetic field signal of DC - several Hz is modulated by a 10kHz AC current like a heart magnetic field and detected, said signal can be detected as a signal having a band of 10kHz + or - several Hz.

IPC: H04N5/92
Filed: 1987-09-16
Abstract: PURPOSE:To decrease a noise component with high accuracy by providing a means to execute conversion to a condition in which a high frequency component is attenuated with prescribed quantity to be smaller than a low frequency component and a means to amplify a high frequency component different from the above mentioned one. CONSTITUTION:For a luminance signal, the high frequency component is extracted in a waveform converting circuit 100, suppressed by the prescribed quantity and outputted to a fixing emphasis circuit 101. The circuit 101 amplifies the high frequency component. The worked luminance signal is supplied through a changing-over switch 102 to a non-linear emphasis circuit 103. Then, the noise component is further decreased by loading normal emphasis and recorded through a limiter circuit 104 and an FM modulation circuit 105 to a magnetic sheet 111. Thus, since the high frequency component, which corresponds to the rising and falling edge parts of the luminance signal, is once suppressed and the emphasis is loaded to the high area component of the suppressed frequency component, the noise component can be decreased.
