Title: Material detecting circuit
Inventor: KAKIZAWA TOSHIO
IPC: G01N27/22
Filed: 1989-05-31
Abstract: PURPOSE:To decide the material of an object of detection without stopping the object temporarily by detecting variation of circuit characteristics, which is caused when the object of detection is inserted into the coil of a resonance circuit, from the amplitude and frequency of a high-frequency signal applied to the resonance circuit. CONSTITUTION:When the object of detection is inserted into the solenoid coil L of the resonance circuit (L and C1), the inductance of the coil L varies owing to the difference of its material, i.e. a magnetic metal body (iron), nonmagnetic metal body (Al), or nonmetal body (glass). Variation in the impedance of the circuit 2 is detected from variation in the terminal voltage across the capacitor C1 or coil L and variation in resonance frequency or peak voltage is detected by varying the high frequency generated by a high frequency generating means (bridge type inverter) 1. The difference of the material can be decided from the detection result. The variation of the circuit characteristics is obtained only by passing the object of the detection through the coil L, so the object need not be stopped temporarily.

Title: Method for joining aluminum material
Inventor: SATO SHOICHI
IPC: B23K1/06
Filed: 1992-05-29
Abstract: PURPOSE:To well join two aluminum materials by interposing Zn based solder between the joint surfaces of both aluminum materials and pressurizing the materials under the specific pressurizing force and further applying ultrasonic vibrations to the one aluminum material. CONSTITUTION:The joint surfaces of the two aluminum materials A1, A2 are pressurized under <=0.01 to 20kgf/mm<2> pressurizing force via a pressurizing lever 5 by a weight 8 for loading in a direction where the joint surfaces are pressed to each other. The ultrasonic vibrations in a vertical direction oscillated from an ultrasonic vibrator transducer are simultaneously imparted to the aluminum material A2 on the left side by a horn 9. Consequently, the oxide films on the joint surfaces of the two aluminum materials are broken by the ultrasonic waves and friction heat is generated between the two aluminum materials and the Zn based solder 11. The solder is then melted and the molten solder arrives at the base of the joint surfaces. The two aluminum materials are thus joined. As a result, the aluminum materials are weld joined without using a flux.
