Title: Resonance signal detection circuit of nuclear magnetic resonance apparatus
Inventor: SHICHIJI KUNIO
IPC: G01R33/36
Filed: 1984-02-29
Abstract: PURPOSE:To enable the detection of a resonance signal with good efficiency by eliminating the effect of an anti-resonant tank circuit, by bringing the diode of the anti-resonant tank circuit to an ON-state by an irradiation pulse. CONSTITUTION:A detection coil L1 resonates at frequency fN(<14>N or <15>N) by a coil L4 and caspacitors C1, C2, C3 to detect the resonant signal of a specimen to be measured. The coil L4 resonates to frequency fD(<2>D) by a capacitor C7 and capacities of diodes D1, D2 and the leakage of the frequency fD to an observation system terminal fNob is held to a min. degree. Further, the coil L1 resonates at the frequency fD by a coil L3 and capacitors C9, C10, C11 and the signal of a <2>D nucleus is detected to form a signal for an internal magnetic field lock. Hereupon, when an irrdiation pulse is supplied from a terminal fNirr to bring diodes D1-D8 to an ON-state, the effect of the frequency fD to a resonant circuit is eliminated. Therefore, the coil L1 resonates at the frequency of the terminal fNirr by capacitors C4, C5, C1, C2 and the irradiation pulse is almost entirely supplied to the detection coil L1.

Title: Control system for access priority
Inventor: TAKAHASHI MASANORI
IPC: G06F13/14
Filed: 1986-02-20
Abstract: PURPOSE:To avoid such a case where the access request of an access request device at each stage is set under an access waiting state by an access processor, by checking effectively and periodically the busy state of the access processor and deciding an access request after selection through each priority deciding circuit. CONSTITUTION:A priority deciding circuit 4 set at the final stage is closest to an access processor 3 and can check a busy state for each machine cycle since the decided access request reaches the circuit 4 immediately. While a priority deciding circuit 4 set at the preceding stage has a different printed circuit board and it needs the time for the decided access request to reach the processor 3 owing to the physical conditions like a clock cycle different from the processor 3, the selection/decision processing time, etc. Therefore the circuit 4 set at the preceding stage checks a busy state which is different from an ordinary busy state and effective in terms of time, i.e., a busy state that may possibly last even after said effective time is subtracted. Then an access request is selected and decided when no such busy state exists. This reduces the probability where the access request produced at the preceding stage is kept while waiting due to the busy state of the processor 3.
