Title: Resistance welding method for al materials
Inventor: TANAKA KAZUO
IPC: B23K11/18
Filed: 1987-05-08
Abstract: PURPOSE:To improve the joint strength and to prevent the surface from cracking by using Al insert material having lower electric conductivity than material to be welded having higher electric conductivity and further, having the thinner plate thickness than either of materials to be welded to perform the welding. CONSTITUTION:The Al alloy insert material 13 is interposed between the plate- shaped materials 11 and 12 to be welded made of Al or Al alloy material and these laminated materials are sandwiched between a couple of bar-shaped electrodes 14. At this time, the insert material 13 has the lower electric conductivity than the material having the higher electric conductivity of the materials 11 and 12 to be welded and its thickness is set thinly than either of the materials 11 and 12 to be welded. When the electrification is carried out between the electrodes 14, the insert material 13 is molten and the materials 11 and 12 to be welded are subjected to the resistance welding. Since the heat generating efficiency of the insert material 13 is high, a nugget 15 becomes flat and the spread of a half-molten area 16 in the direction of the plate thickness is restrained. Accordingly, the joint strength is improved and the occurrence of the cracking is prevented.

Title: Waveform shaping circuit
Inventor: NAKAMURA MITSURU
IPC: H03K5/08
Filed: 1977-09-16
Abstract: PURPOSE:To obtain easily a square waveform with the same pulse width as a transmitted waveform, and to eliminate the need of an adjustment of a detection level by shaping waveforms by a comparator which employs the DC component extracted from a transmitted signal as the detection level. CONSTITUTION:In the signal transmitting equipment of the inversion transfer system (ON and OFF signals are received at the same rate), a DC component is extracted from a received waveform and used as a detection level since the optimum detection level value of the waveform shaping circuit of a receiver is equal to the value of the DC component of the received waveform, so that the optimum detection level can be set automatically which corresponds to the received waveform. When the time constant of filter circuit 27 is made much larger than the AC component of the received waveform, the DC component extracted by circuit 27 is taken out efficiently by voltage-follower circuit 28 and then, inputted as the detection level to inversion input 10 of comparator 8, where it is compared 8 with the directly- received waveform of non-inversion input 9, thereby obtaining a signal with the same pulse width as the transmitted waveform from output terminal 11.

Title: Automatic polarity matching dc power source cord
Inventor: TAJIRI NOBORU
IPC: H01R13/64
Filed: 1996-05-01
Abstract: PROBLEM TO BE SOLVED: To simplify the work and enhance the safety by providing an automatic polarity matching circuit and an ac output preventing circuit between an input terminal and an output terminal. SOLUTION: An input terminal 11 has an inductance 12, an electromagnetic switch 13, and a rectifying element 14, and the contacts 13A, 13B of the electromagnetic switch 13 are interposed along a power source line. When a dc voltage is connected to the input terminal, an output terminal 8 can obtain a constant polarity by the rectifying element 14 regardless of the polarity connected to the input terminal. Since the voltage drop by the inductance is small when the dc voltage is connected to the input terminal, the electromagnetic switch 13 is operated to close 13A, 13B, whereby a dc output is supplied to the output terminal. Since the electromagnetic switch 31 can not be operated when an ac power source is connected to the input terminal, no ac output is supplied to the output terminal. According to such a structure, simplification of work, prevention of damage of equipment, and improvement in safety can be attained.
