Title: Arc welding machine by short circuit transfer
Inventor: TABATA YOUICHIROU
IPC: B23K9/10
Filed: 1981-10-23
Abstract: PURPOSE:To provide a titled welding machine which permits welding with regular short circuit transfer and change in arc length, by providing a means for on-off controlling of welding current in such a way that the welding voltage value particularly in a short circuit period and arc period is transferred along the waveform of a reference short circuit voltage, and the waveform of a reference arc voltage. CONSTITUTION:This arc welding machine by short circuit transfer is operated as follows: Welding current is so controlled that the welding voltage increases along the waveform of the predetermined reference short circuit voltage from the point of the time when a wire electrode short circuits with base materials. The welding current is so controlled that the welding voltage decreases along the waveform of the predetermined arc voltage from the point of the time when the arc is regenerated between the wire electrode and the base materials. More specifically, the fluctuations in the short circuit period and the fluctuations in the arc period owing to changing over of the wire feed speed, hand shaking, etc. are corrected automatically by such controlling.

Title: Parity generating/checking method
Inventor: ISHIKAWA HAJIME
IPC: G06F11/10
Filed: 1990-06-28
Abstract: PURPOSE:To perform the parity check of a word size even though a byte write access is applied to a microcomputer in a size smaller than the word size by operating a control signal in a read/write state. CONSTITUTION:When a byte write access is applied to some of dynamic RAM 4 - 7 in a size smaller than the word size of a microcomputer 1, the write data is outputted to an access RAM from the microcomputer 1. Meanwhile a byte read access is applied to a non-access RAM respectively. Then the data equivalent to the word size are outputted to the data buses of the RAM 4 - 7. Based on these data, the parity data is produced and stored. Then the read accesses are always applied to the RAM 4 - 7 for each word size in a read access state, and the parity check is carried out. Thus the parity check is attained for each word to the microcomputer 1 together with the parity check also attained in a write access state.

IPC: F25J3/04
Filed: 1994-07-22
Abstract: PURPOSE:To maintain heat exchanger duty in a condenser constant in spite of changes in nitrogen purity in argon gas by installing a variable resistance between an upper tower of a duplex fractionating column, at least a part of which is constituted by packing, and a coarse argon tower. CONSTITUTION:During rated operation or when nitrogen purity in argon gas is not varied, an automatic valve (resistance) 14 provided on a feed line 8 between an upper tower 1 and a coarse argon tower 4 is throttled to make pressure at a top of the coarse argon tower 4 minimum. Also, in the case where nitrogen purity in argon gas is increased, the automatic valve 14 is opened to raise pressure at the top of the coarse argon tower 4 to increase temperature at the top of the tower, thus making a temperature difference between a coarse argon gas and a liquid fluid constant. An opening degree of the automatic valve 14 is determined by an arithmetic unit 16 which calculates pressure so that heat exchanger duty in a condenser 5 is made even by that nitrogen purity in argon gas which is detected by a nitrogen analyzer 13.

IPC: G01C19/30
Filed: 1982-09-30
Abstract: PURPOSE:To adjust a raised position easily by arranging a ferromagnetic material near a coil. CONSTITUTION:An iron piece 7 is made of the ferromagnetic material and an N and an S magnetic pole embedded in a rotor 1 attract each other, so the rotor 1 receives average torque in the direction of the iron piece 7 during rotation almost to enter pression at right angles. On the other hand, the coil 4 for raising is to supply the torque which returns the rotor 1 to the original raising position where the iron core 7 is absent. Consequently, the rotor 1 stays at the balancing point between the torque of the iron core 7 and that of the raising coil.

Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To improve receiving signal level, by changing the crossing angle of center lines of a transmitting sensor and a receiving sensor, in the range of a specific angle, and shortening the distance from a contact to a targets. SOLUTION: An angle changing jig 11 moves a transmitting sensor 5 and a receiving sensor 6 of arm parts on a circular arc of a constant radius by rotating a rotary part. The crossing angle of center lines of both the sensors 5, 6 is changed in the range from 80 deg. to 120 deg.. An ultrasonic wave which propagates from the transmitting sensor 5 to a detected object and is reflected is received by the receiving sensor 6. A receiving signal estimating equipment 13 compares the receiving signal level based on the output from the receiving sensor 6 with the level before the angle between the sensors 5 and 6 is changed, and outputs an angle conversion signal according to the comparison result. The angle changing jig 11 charges the angle α between the sensors 5 and 6 obtains the angle α which maximizes the receiving signal level.  Flaws of the object are detected by the angle α between sensors 5 and 6 which maximizes the receiving signal level.
