Title: Method for quality assurance and checking of resistance weld zone
Inventor: NAKADA SHIYUUJI
IPC: B23K11/25
Filed: 1981-01-30
Abstract: PURPOSE:To assure the quality of a weld zone and to check the same surely bt setting  a change of the voltage between electrode tips at which the good weld zone is obtainable with time as reference voltage and controlling welding current in such a way that  the voltage between the tips is kept within this permissible range. CONSTITUTION:A circuit 5 detects the voltage Vd between electrode tips 2a, 2b momentarily except in the initial period of conduction of electricity. This is compared with  the above-described reference voltage Vr changing with time from a circuit 7 in a circuit 6, and a differential signal Sd is emitted. On the other hand, the signal Sr of a  circuit 9 is made into Sr' with a circuit 10, and a circuit 8 operates the firing phase  angle of a circuit 11 with this and Sd, and a circuit 11 generates firing pulses by the  signal S  thereof, thereby controlling the primary AC waveform of a transformer 4.  When voltage Vd Vr, Sr'=Sr and the circuit 11 is controlled of the firing phase angle  in such a way as to flow reference welding current. The voltage V1 of an electric  power source 3 and the voltage Vs from a circuit 14 are compared momentarily, and a differential signal Sf is fed to the circuit 10. The circuit 8 corrects the signal S  by  as much as the signal Sf so that the reference welding current value is prevented from  fluctuating despite fluctuation of the voltage V1.

Abstract: PURPOSE:To eliminate the need for a mounting discrimination signal generation part and to simplify the circuit constitution by supplying a common signal to a package discrimination terminal of an individual package corresponding to the kind of this individual package and using a common signal which is outputted from a slot discrimination terminal of a slot as a discrimination signal. CONSTITUTION:When the common signal U is supplied from a common package C to common signal output terminals F of slots SL1-SL3, the common signal U reaches package discrimination terminals M1-M3 of individual packages A1-A3 which are made to correspond to the individual packages A1-A3 through the common signal input terminals E of the individual packages A1-A3. The common signal U reaching the package discrimination terminals M1-M3 becomes discrimination signals T1-T3 through slot discrimination terminals N1-N3 connected to the package discrimination terminals M1-M3 and those discrimination signals T1-T3 are inputted to a common package C. If the individual packages A1-A3 do not match the corresponding slots SL1-SL3 and are mismounted, the common signal U does not reach the slot discrimination terminals N1-N3 of the slots SL1-SL3, so the discrimination signals T1-T3 are not sent out to the common package C.

Title: Grinding for formation of discharge aperture surface of ink jet head
Inventor: KOSAKAI TAKASHI
IPC: B41J2/16
Filed: 1990-01-24
Abstract: PURPOSE:To minimize the gradient of a discharge aperture surface of an ink jet head and thereby increase the accuracy of a finished size by grinding the aperture surface and the reference surface of a fixture uniformly by the size of a cut margin without deflection to form the discharge apertus. CONSTITUTION:A preworking size Xn is measured and a sum (W+Z) is obtained by adding a cutting margin Z to an objective size W. Then the difference (W+Z) -Xn obtained by subtracting the preworking size Xn from the sum (W+Z) is given as a regressive size Yn. Consequently, the sum (Xn+Yn) obtained by adding the regressive size Yn to the preworking size Xn is equal to the sum (W+Z). This relationship is established at optional n-th measurement place. That is, if an ink jet head is fixed by moving an aperture surface before working backward from the reference surface of a fixture by a regressive size at each measurement place, the lines drawn by the reference surface of the fixture and the tip of a reference pattern become aligned in parallel with each other after being separated from the other by the sum (W+Z). In this state, the reference surface of the fixture is ground uniformly with the aperture surface without deflection. Therefore, the discharge aperture surface is finished along a line drawn by the tip of the reference pattern.

Filed: 1981-01-29
Abstract: PURPOSE:To manufacture a locking nut of high hardness simply and cheaply by annealing only a projected periphery in the upper part of a screw hole, thrusting an elastic ring in, and bending the projected periphery inside. CONSTITUTION:When a nut body 1 is fed from a feeding device 4 to a concave part 5a of a shifting stand 5, the nut body is heatd by heating devices 7 successively from low temperature to high temperature while moving.

It is then cooled naturally while it moves in the range S, and a ring body 3 is thrusted and fitted in a concave part. When it arrives at a caulking device 9, a press comes down and presses the upper end of the projected periphery to bend it inside. Thus a product is obtained. The product falls down automatically from an outlet 10 and recovered.
