Filed: 1991-11-18
Abstract: PURPOSE:To attain 2-channel transmission per one carrier by applying amplitude modulation to a 1st or 2nd carrier with a prescribed phase difference by a 1st or 2nd information signal and sending the modulated signal while the carrier is being suppressed and allowing a receiver side to apply synchronization detec tion with a 1st or 2nd demodulated carrier generated based on a phase of a reference signal wave. CONSTITUTION:A reference signal omegaC from a reference oscillator 2 is sent to an incoming band (low group), a head end 1 applies frequency conversion to an outgoing band (high group) and the result is reflected. A phase comparator 120 and alpha, -alpha phase shifters 150, 160 or the like receiving the reference signal are used to generate 1st and 2nd modulation carriers having a phase difference 2a with a frequency omegaC. The carrier is subjected to amplitude modulation by 1st and 2nd information signals and a BPF suppresses the carrier to send only both side bands. The 1st and 2nd demodulated carriers are used to demodulate the received signal by pi/2-alpha, +alpha phase shifters in a receiver and the 1st and 2nd information signals are outputted through synchronization detection. Thus, 2-channel transmission per one carrier is attained.

Filed: 1988-12-27
Abstract: PURPOSE:To reduce the area of a write driver circuit occupied on a chip by providing plural inverters and MOS transistors (TRs) and activating them with a few elements. CONSTITUTION:When a write control signal WDE reaches a logical high level, the inverter 2 goes to a low level. Then P-channel MOS TRs QP1, QP2 and N-channel MOS TRs QN1, QN2 are turned on.

Filed: 1988-12-27
Abstract: PURPOSE:To enlarge the execution range of fuel cut control so as to improve fuel consumption by setting a fuel cut recovery rotational speed so that it becomes a larger value as slip rates of driving wheels become larger, on the basis of the output of a slip rate calculating means. CONSTITUTION:When it is judged by a judging means M3 that a rotational speed is more than a prescribed fuel cut starting rotational speed, at the time of deceleration run of an internal combustion engine M1 detected by a detecting means M2, fuel cut control is started by a control means M4. When it is judged by a judging means M5 that the rotational speed decreases below a fuel cut recovery rotational speed, fuel feed is resumed by a recovery control means M6. In this occasion, the fuel cut recovery rotational speed is set by a set means M10 so that it becomes a larger value as the slip rate of a driving wheels M7 calculated by a detecting means M8 and a calculating means M9 becomes larger. Thus, the fuel cut recovery rotational speed is set to a value corresponding to a road surface mu, and the execution range of fuel cut control is enlarged within a range in which no engine stall takes place so as to improve fuel consumption.
