Title: Extension pencil for automatic plotter
Inventor: KONNO TAMAYOSHI
IPC: B43L13/00
Filed: 1991-11-13
Abstract: PURPOSE:To provide extension pencil whose lead is extended automatically by making holding force of a chuck unworkable on the lead at extending the lead. CONSTITUTION:A slide ring 23 is fixed to an end part of a lead receiving side of a lead holding tool 16 in an extension pencil. A rear part of a lead holder 12 is extended and an inner periphery of a tip 12a of an extension 12a of the holder 12 is contacted to the peripheral face of the slide ring 23. The friction force of the slide ring 23 and the extension 12a of the lead holder is larger than a thrust of a chuck closing spring 19 of a piece of chuck 18 of the lead holding tool 16. A thrust of a lead holder press-down spring is made to be larger, or a lead holding force of a lead holding piece 15 to be provided at the lead holder 12 is made to be larger than the thrust of the chuck closing spring 19. Thus, the lead is pulled out after the chuck is opened, so that the lead holding at the chuck does not slip, thereby improving durability.

Title: Ultrasonic transmitter-receiver
Inventor: OGURA KOJI
IPC: H01L41/45
Filed: 1989-11-15
Abstract: PURPOSE:To improve the wave transmission and reception characteristic by forming a piezoelectric element with flexible composite piezoelectric material and forming a damping member with a mixture comprising porous resin and ceramic particles. CONSTITUTION:The piezoelectric element is made of a flexible composite piezoelectric material and the damping member is made of a mixture of porous resin and ceramic particles. Thus, when an undesired vibration wave caused at the rear side of the piezoelectric element propagates in the damping member having air holes in it, the part of the wave collides sequentially with lots of air holes and collides with each other and is reflected irregularly, diffused and lost. Moreover, the other part of the wave is converted into heat energy due to vibration of ceramic particles and molecular friction with surrounding resin. Thus, a large attenuation effect is enhanced as a whole. Then the wave transmission reception characteristic is improved.
