Title: Error recovery processing method for data processor
Inventor: KANEKO AKIRA
IPC: G06F12/10
Filed: 1986-05-07
Abstract: PURPOSE:To obtain the correct key information from the nondefective one of an address conversion mechanism TLB and a memory key cache memory CACH in case either the TLB or CACH has an error, by adding TLBAD corresponding to a read address of the TLB to the CACH. CONSTITUTION:When an access address is supplied to a TLBIB via an address input signal line 1a, the TLBIB is supplied to a parity check circuit 2 after the corresponding key data KEY and a key parity KP are read out. In case the circuit 2 has an error, an access is given to a CACH by a REALAD outputted from the TLBIB. Then the output of the TLBIB is delivered via a selector 11 as long as an address exists and the parity check is normal. For an access address supplied to the CACH, the output of the CACH is also outputted after the normal data is read out by a TLB in an error mode. Thus the cross reference is possible with key information between the TLB and the CACH and the applicability is improved.

Title: Bnzs code deciding method
Inventor: MURAKAMI KOU
IPC: H04L25/49
Filed: 1987-04-28
Abstract: PURPOSE:To obtain digital transmission excellent in quality by deciding n-bit into n-piece of '0s' even if the operation is out of the BnZS code rule when two violation pulses in the n-bit are detected. CONSTITUTION:When 2-violation pulses in the n-bit are detected, even when the operation is out side of the BnZS code rule, the n-bit is decoded into n-set of '0s'. Suppose that a pulse train '+000+-0+00' shown in figure (a) has one error and becomes a pulse train '+00+-0-000' as shown in figure (b). That is, an error is considered such that one positive pulse is regarded to be missing. In such a case, since two violation pulses exist in 8-bit, the result is decoded into '10000000000' as shown in figure (c). This is the correct decoding when no error exists.

Title: Measuring method for permittivity by microwaves
Inventor: NAGATA SHINICHI
IPC: G01N22/00
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To obtain a measuring method whose measuring accuracy is enhanced by a method wherein, when a permittivity is measured by using a resonator in which a gap is formed, the deviation of a resonance frequency due to the disorder of a microwave electric field due to the gap is corrected. SOLUTION: Resonance frequencies in the case of gaps of different sizes are measured by samples of different permittivities. On the basis of the difference between the frequencies and a theoretical frequency by a computation, the conversion expression of the measured value of a resonance frequency which is extrapolated into a gap 0 and of the measured value of a resonance frequency in the case of a specific gap at an actual machine is derived as fi'=αfi-β, where fi' represents a corrected resonance frequency, fi represents a resonance frequency at the actual machine at a gap X, and α and β represent constants.  By using the corrected resonance frequency fi which is found by the expression, a permittivity ε' is computed by a computing expression of ε'=1+(X0 /t) (f1 '-f2 ')/f1 '}, where f1 ' and f2 ' represent frequencies whose resonance frequencies are corrected when a blank and an unknown sample are measured at the actual machine, and X0 represents a value in which a gap length is subtracted from a resonator.
