Filed: 1990-03-22
Abstract: PURPOSE:To obtain a motor which operates regardless of drive frequency, contrary to a supersonic motor which utilizes a conventional resonance mode, by utilizing a non-resonance piezoelectric vibration of a piezoelectric element. CONSTITUTION:A straight line which connects a hinge 13 and a center of a circular hole 12 is at 90 degrees with that which connects a hinge 14 and the center of the circular hole 12. When sinusoidal wave voltages ranging from 0 to 150V where the phase differs by 90 degrees are applied to piezoelectric elements 1 and 10, connection parts (hinges 13 and 14) to the drive plate 11 in a displacement amplification mechanism are displaced in inverse direction by 5.0mum each and the drive plate 11 oscillates around the circular hole 12 with a diameter equal to the displacement at the tip of the displacement amplification mechanism is its diameter. A rotary shaft 15 is in contact with the side surface of the circular hole 12 at one point so that friction force operates on the rotary shaft 15 in tangential direction, thus enabling the rotary shaft 15 to perform rotational motion. Since the rotary shaft 15 and the circular hole 12 of the drive plate 11 are eccentric, their contacting points change and move in sequence.

Title: Package structure of electronic part
Inventor: SHIMAMOTO HARUO
IPC: H01L23/50
Filed: 1986-03-31
Abstract: PURPOSE:To prevent the rising-up of solder at along a lead part the time of reflow of solder paste and to prevent poor bonding and a gap between the lead part and a substrate, by providing a rise-up preventing configuration part at the lead part. CONSTITUTION:A weir 4 forms a protruded surface at the intermediate part of a lead part 2. When solder paste, which is provided between a substrate conductor part and the tip part of the lead part 2 at the time of packaging, undergoes reflow, the surface tension of the solder acts on the protruded surface. The surface tension acting on the protruded surface suppresses rise-up of the solder along the lead part 2 owing to the surface tension. Thus, the bonding of the substrate conductor part and the lead part with the solder is ensured.
