Title: Method for compensating temperature of air to fuel ratio sensor
Inventor: ICHIKAWA NORIO
IPC: G01N27/41
Filed: 1988-09-16
Abstract: PURPOSE:To prevent the degradation in detection accuracy by the deterioration of the heating element of a heater by detecting the change component of the heater for heating with time, returning the component to a bridge circuit and compensating the same. CONSTITUTION:The voltage to be impressed to the bridge circuit 10 is designated as V1. The differential voltage DELTAV generated by a comparator 3 increases with time if the initial value changes as a result of the change of the ceramics heater 1 having the W heating element with age. The bridge circuit 20 is constituted of a voltage dependent type resistance element 4, the heater 1, and resistors R1, R2'. The resistance value of the element 4 is increased and controlled by the differential voltage DELTAV generated by the circuit 10 according to the differential value DELTAV, by which the resistance value is changed. The detection voltage DELTAVA of a temp. control circuit part including a comparator 5, a power transistor Tr 6, etc., is detected as the differential voltage of the comparator 5. The voltage DELTAVA is fed back to the bridge circuit and is controlled by turning the heater 1 and the Tr 6 on and off so as to decrease the voltage to zero. The change component of the heater 1 with age is detected and compensated in this way.

IPC: G08G1/0968
Filed: 1990-08-31
Abstract: PURPOSE:To find the present position of a vehicle by a crew by constituting a running- state recognizing means of a right-wheel-speed sensor and a left-wheel-speed sensor, and providing a control means for judging whether the moving direction of own vehicle is in advancing direction or the backing direction based on the signals. CONSTITUTION:The pulse output from a left wheel and the pulse output from a right wheel are compared based on the data from a running-state recognizing means 50. When the pulse output from the left wheel is equal to the pulse output from the right wheel, it is judged that there is no direction change. When the pulse output from the left wheel is larger than the pulse output from the right wheel, the output change from a bearing recognizing means 40 is checked. When the output change from the bearing recognizing means 40 is counterclockwise, advance is judged. When the output change from the bearing recognizing means 40 is clockwise, backing is judged. When the pulse output from the left wheel is smaller than the pulse output of the right wheel, the output change from the bearing recognizing means 40 is checked. When the output change from the bearing recognizing means 40 is clockwise, advance is judged. When the output change from the bearing recognizing means as counterclockwise, backing is judged.

Title: Slag removing method of weld zone
Inventor: MATSUI HITOSHI
IPC: B23K26/142
Filed: 1983-12-05
Abstract: PURPOSE:To reduce a welding cost, etc. by irradiating laser light to the remaining slag in a weld zone to decompose the slag and blowing a compressed gas to the weld zone to scatter the slag. CONSTITUTION:Laser light 4 conducted from a laser oscillator is condensed by a lens 5 and is irradiated to slag 3. The slag 3 is melted by the laser energy or is cracked by thermal stress. When a compressed gas is blown from a nozzle 6 at the same time of irradiation of the laser light, the molten or cracked slag 3 is blown off from the trough between the beads 2. The laser light 4 reflected from the beads 2 is also concentrated to the slag 3, by which the slag is decomposed in short time. The temp. ecrease in the weld zone is decreased by such method and the weld time for multi-layer build-up is reduced. Since the wasteful consumption of the material is prevented, the cost of welding is reduced.

Abstract: PROBLEM TO BE SOLVED: To prevent clogging of a conduit of an emulsion spraying apparatus, by providing a cleaning means for cleaning the apparatus, to thereby prevent solidification of emulsion in the conduit at the time of stopping spray of the emulsion, or the like. SOLUTION: At the time of spraying emulsion, the emulsion in an emulsion tank 7 is sprayed from a spray nozzle 10a to a bedrock by means of a pump 12. At the time of circulating the emulsion before the spraying or the like, the emulsion in the tank 7, which has been heated by a heater, is circulated through a conduit by means of the pump 12, to thereby keep warm the conduit 14 and a spray portion. When the emulsion is charged in the tank 7 or discharged from the tank 7, an emulsion supply/exhaust port of an emulsion supply vehicle is connected to an external connection port 18. Further, when the emulsion spraying apparatus is cleaned after completion of the spraying operation, the pump 12 is driven, to thereby return a cleaning liquid in the tank 11 through predetermined passages such as a spray bar 10, the pump 12, a filter 13, a pipe 14, and a valve 15, to the tank 11.  Further, the cleaning liquid is injected from the spray nozzle 10a. Thus, clogging of the channels due to coagulation of the emulsion remaining in the respective channels can be prevented, to thereby increase the reliability of emulsion spray.

Abstract: PROBLEM TO BE SOLVED: To obtain a radio transmission system, a radio transmitting method, a transmitter and a receiver capable of securing a more than twice of transmission bit rate in the case of one radio transmitter by using the radio transmitters by combining two or more radio transmitters when no sufficient transmission bit is secured by one radio transmitter due to band restriction and transmitting a high definition television signal in a form of an OFDM signal by radio. SOLUTION: OFDM signals with different occupying frequency band which is obtained by up-conversion from a transmission high frequency part TX-H #1, TX-H #2 and TX-H #3 to transmission frequency bands CH1, CH2 and CH3 are amplified by an amplifier 6 after they are synthesized and converted into a synthetic OFDM signal by a synthesizer 5 and after that transmitted by radio. A TS signal with a bit rate of 8 Mbps is obtained by performing a specified signal processing by a reception control part RX-C 8. Three TS signals outputted in parallel from the part RX-C 8 are inputted in a TS synthesizer and one TS signal is outputted by successively rearranging the three TS signals. Therefore, when each of bit rates of the three TS signals outputted in parallel from the part RX-C 8 is 8 Mbps, the TS signal of 24 Mbps is outputted from the TS synthesizer.
