Title: Encoder signal processing multiplier
Inventor: HASEGAWA HIDENORI
IPC: G01D5/245
Filed: 1992-08-05
Abstract: PURPOSE:To provide an encoder with high resolution without use of a biphase carrier signal with high accuracy by counting a width or a purse signal obtained by comparing either of a phase A or a phase B signal being an incremental signal with a reference triangle wave so as to interpolate a level within one pulse width of the incremental signal. CONSTITUTION:A phase A signal is compared with a reference triangle wave outputted from a reference triangle wave signal generator 107 at a comparator 106. The pulse width of the output pulse from the comparator 106 varies with a signal level (rotating angle). The pulse width is counted by a counter 108. Data representing a position of an incremental signal within one pulse width according to the count of the pulse width are prepared in a ROM as a table. That is, the output of the counter 108 is used for an address. The position data are outputted by a correction arithmetic operation device 111 based on the count of the pulse width (ROM address) by the counter 108 and discrimination of a quadrant by a quadrant discrimination device 110.

Title: Photoelectric conversion element
Inventor: KOUCHI TETSUNOBU
IPC: H01L31/10
Filed: 1989-09-08
Abstract: PURPOSE:To dispense with the formation of an element isolating region by arranging a first photoelectric conversion element and a second photoelectric conversion element, adjacently. CONSTITUTION:Semiconductor are as (15, 17, and 18) and (13, 14 and 19) constitute an NPN bipolar transistor, and the semiconductor areas (15, 17 and 18) and (13, 14 and 19) constitute base regions, collector regions, and emitter regions, respectively. The potential of the semiconductor region 17 to become the collector region is maintained at specified positive potential or negative potential through an embedded layer 16. The positive holes created by applied light accumulate in the base region, and NPN type bipolar transistor functions as a photoelectric conversion element. At this time, the semiconductor areas 13 and 17 to become the collector region are in reverse-bias condition, so a large number of carriers within the collector are prevented from shifting between picture elements, and a small number of carriers do not contribute to the accumulation even if they leaked into adjacent picture elements, so as a result element isolation can be done without newly providing an element isolating region.

Title: Method of recovering insulating resistance of deteriorated cv cable by water tolly
Inventor: MINAGAWA ITARU
IPC: H01B9/00
Filed: 1991-09-11
Abstract: PURPOSE:To recover dropped insulation yield strength by letting a current flow to the conductor of a CV cable, and elevating the temperature of an insulator to the vicinity of its heat resistance, and preserving its condition for a certain time. CONSTITUTION:Among three CV cables 1, the cable heads 2 on one side of two CV cables 1 are connected to a power source 4 by a lead wire 3 for current carrying, and the cable heads 2 on the other side are short-circuited by a lead wire 3 for current carrying so as to form a current-carrying circuit. The temperatures of the conductor of the CV cable 1 and the insulator are elevated by letting a current flow to this current-carrying circuit. For example, the temperature of the conductor of the CV cable 1 is kept at 90 deg.C, and the condition is continued for 50-60 hours. As to the remaining one, it can be processed by repeating the same method, in combination with already processed one. In case that the temperature of the conductor is lower than 90 deg.C, it is made longer than the preservation time. Hereby, the insulation yield strength of the CV cable deteriorated by water tolly can be recovered in the condition where it is laid.

Title: Data processing device in fm multiplex broadcasting receiver
Inventor: KIMURA KAZUHIRO
IPC: H04L1/00
Filed: 1995-09-11
Abstract: PROBLEM TO BE SOLVED: To inhibit the scramble release operation for unnecessary data when the error correction for a data packet to be a processing object is discriminated as an error. SOLUTION: FM demodulation data for which a demodulation/error correction is performed is stored in a data register 102 via an input circuit 101. A data analyzing circuit 104 generates a scramble key from input data and supplies the key to a scramble release data generation circuit 105. The scramble release data generation circuit 105 generates a scramble release code PNOUT, which is supplied to an exclusive OR gate 110 in synchronism with the data from a data register 102 and released with a scramble. A status register 103 decides whether the error correction for data is correct or erroneous from the status information given to the leading of demodulation data and supplies a '0' signal to an AND gate 108 in the case of the error.  Thus, the clock CK 2 is not outputted from the AND gate 108 and the scramble release data generation circuit 105 stops the output of a scramble release code PNOUT and a scramble release in inhibited.
