Title: Position controlling device for weaving welding
Inventor: HARIKI KAZUO
IPC: B23K9/02
Filed: 1982-06-15
Abstract: PURPOSE:To obtain a highly accurate position controlling device that can response at high speed, by utilizing self stability of arc current in weaving and obtaining a signal proportional to the distance of arc current and base metal at high S/N value. CONSTITUTION:A torch 3 is positioned on the weld line of a pair of base metal 1, 2 to be welded, and moved by a machine 4 along the weld line. Welding is started by weaving it within the range of A, B, and arc current is detected by a detector 5. A phase control circuit 9 converts the detected value to a signal proportional to the change of weaving position. A timing control circuit 15 perceives delay of response of the circuit 9 and device 4 from weaving frequency, and sends sampling pulse from weaving phase signal. A memory 16 compares output of the circuit 9 at each pulse, and presets deviation between a position where the difference signal is zero and the proper position of actual weld line. A peak value operator 12 obtains the difference signal and controls the position of the torch to a proper position where the difference is zero through a control circuit 13.

Title: Method of controlling feed of fuel during shut off of feed of fuel for internal combustion engine
Inventor: KISHI NORIYUKI
IPC: F02D41/36
Filed: 1986-04-30
Abstract: PURPOSE:To prevent the occurrence of a trouble due to production of lean air-fuel mixture, by a method wherein, when it is discriminated that an internal combustion engine is in a high load running state when the fuel feed shut off condition of an internal combustion engine is established, the feed of fuel is shut off after a given amount of fuel is fed. CONSTITUTION:An ECU 8 receives various engine paramenter signals from various sensors 7, 10, 12-14, and 16 by means of an input circuit 8 to discriminate the running state of an engine 1 by means of a CPU 8, and according to the discriminating result, a fuel injection valve 4 is driven and controlled through the working of an output circuit 8d. In this case, when the fuel feed shut off state of the engine 1 is established, the running state of the engine 1 right before establishment of the condition is discrimnated. When it is discriminated that the engine 1 is in a high load running state, after a given amount of fuel is fed, the feed of the fuel is shut off. This constitution prevents pre-ignition from occurring as a result of air-fuel mixture being brought into a lean state after the feed of the fuel is shut off under a high load running state, and exhaust of unburnt gas.

IPC: G01V8/20
Filed: 1993-04-06
Abstract: PURPOSE:To correctly detect the road surface reflection even if traffic jam is generated, by judging the road surface reflection detection point output at the time point when the top part of a vehicle which passes before a road surface reflection detection point by a prescribed distance is detected, as the reflection supplied from the road surface. CONSTITUTION:In order to detect the top part of a vehicle 4 which travels before a main beam 2 by a prescribed distance, a subbeam detector 11b for sending out subbeam 3 before by a prescribed angle is installed on a light transmission/receiving part 11 of the detector. The prescribed distance is set to the little longer distance than the between-vehicle distance in the case where the between-vehicle distance which is proper for securing safety for the preceding vehicle is kept. The top of the vehicle 4 is detected by the beam 3, and if the reflection is detected after the vehicle 4 has passed through the beam 2, it is judged as the reflection supplied from a road surface, and if a change is generated in the beam 2 within a prescribed time after the vehicle 4 is detected by the beam 3, the detection value is not judged as the road surface reflection. Accordingly, the road surface reflection signal as the standard for detecting the passing vehicle can be detected surely.

Title: Nc program editing device
Inventor: MEGURO TATSUYA
IPC: G05B19/416
Filed: 1986-05-06
Abstract: PURPOSE:To perform the debug processing in terms of the NC program speed in an easy, quick and assured way by securing an interlocking operation between an editing device an a machine tool and reflecting the over-ride value set by an operator directly on the NC program. CONSTITUTION:An NC program input part 2 supplies an unedited NC program P1 in terms of the feed speed and sents it to a store file 3. A subroutine call instruction inserting part 4 puts a subroutine call instruction into the program P1 to set the over-ride value at an NC machine tool M against the feed speed written in response to a sequence number. This call instruction is transmitted to an NC program executing part M1 of the tool M via an NC program transfer part 5. An NC program editing part 8 converts the contents of the file 3 into the speed value based on the over-ride value stored in an over-ride value file 7 to obtain a new NC program P2. Therefore, the input program P1 is executed by the tool M and the over-ride value set by an operator as necessary can be automatically edited.

Title: Circuit for detecting coincidence of output from counter
Inventor: KOMODA TAKUYA
IPC: H03K23/66
Filed: 1982-06-15
Abstract: PURPOSE:To compensate time shear until the stabilization of each bit in a counter circuit at the time of digit shifting by inputting the output of each bit of the counter consisting of plural bits to a gate for detecting coincidence through a sequential delaying element. CONSTITUTION:The initial value of a counter circuit consisting of 9 bits is set up by initial value input terminals PRE1-9, and when all outputs A'-I' are ''1'', i.e. coincidence of the minimum value is detected, the outputs of respective inverters G5-G7 are delayed by stages until the state of respective bits is stabilized by using the characteristic that the delay time of a delay circuit of one gate in an NAND gate is 25ns, which is sufficiently smaller than a clock period (10mus). Since the delay of an output from the inverter G7 is 25ns by the superposition of outputs H', G', F', the outputs of the inverters G5, G6 are delayed by 25ns or more and the outputs of the inverters G5, G7 are delayed by 50ns or more in stages. Consequently, incorrect detection of coincidence is prevented at the time of shifting from the upper digit to the lower digit.
