Title: Error correcting device
Inventor: INOUE TORU
IPC: H03M13/00
Filed: 1995-03-01
Abstract: PURPOSE: To detect that the symbol pattern corrected by a decoder is equal to an error pattern which is hard to occur in terms of probability and then to use the error pattern as the disappeared one for the decoding. CONSTITUTION: A memory 22 stores a bit pattern included in the symbol of an error pattern that is acquired by a decoder. If the bit pattern is identical with at least one of error patterns acquired by the C1 decoding in terms of both addresses and patterns, the error pattern is corrected. If both patterns are not coincident with each other, the occurrence of a wrong correction is decided and a disappearance flag is added. Then the disappeared patterns is corrected in the C2 decoding. Then if the number of disappeared patterns exceeds the largest number (d2-1) of input corrected disappeared patterns of the C2 decoding, the correction is carried out by means of the patterns stored in the memory 22 with the least number (ordinary 1) of patterns remained there. Thus the number of disappeared patterns is kept less than (d2-1) and the correction is carried out in the C2 decoding.

Title: Electric power making detecting circuit
Inventor: HIRATA MASAKI
IPC: H03K17/22
Filed: 1981-03-23
Abstract: PURPOSE:To normally operate an integrating circuit to be used for charging capacity elements at the time when the power supply is instantaneously cut, by assembling a unilateral conductor element whose one end is grounded and which has a low internal resistance, into the integrating circuit. CONSTITUTION:When a supply voltage VDD rises by making the power supply, a capacity element 12 is electrically charged through an MOSFET11, but, when the internal resistance of the FET11 is increased and the capacity value of the element 12 is enlarged, the rising speed of a voltage VA' at a point A' can be made slow sufficiently against the rising speed of the supply voltage VDD. By the action of FETs 15, 16, a voltage VC' at a point C' rises quickly after the power supply is made as the voltage VDD rises, and, when the voltage VA' rises, the internal resistance of the FET16 drops, and the FET16 becomes conductive, the voltage VC' quickly drops and forms a reset pulse. When the power supply is instantaneously cut and the voltage VDD drops lower than the voltage VA', an FET18 works as a diode having a low internal resistance and the capacity element 12 quickly discharges the electricity.

IPC: H02P29/00
Filed: 1986-02-27
Abstract: PURPOSE:To enable PLL to be reset automatically to a locked state by correcting voltage for setting a rotational speed with correction signal, when it is detected from the output of a phase comparator that the PLL is not locked. CONSTITUTION:A phase comparator 1 supplies phase difference signal V1 between reference signal fR and signal fE from an encoder 6 to a low-pass wave filter 2. An adder 3 adds the output V2 of the low-pass wave filter 2, voltage V3 setting a rotational speed, and correction signal DELTAV3, and feeds the result to a servo-amplifier 4. When PLL gets out of lock, then the signal of the differentiated phase difference signal V1 exceeds the threshold value of a comparator 9 or 10, and so count action is performed by a counter 11 or 12. A CPU 16 selects either switch circuit 17 or 18 depending on which counter 11 or 12 and performs counting and outputs the correction signal DELTAV3.
