Title: Reciprocating type electric shaver
Inventor: YASUNAKA SHINSAKU
IPC: B26B19/28
Filed: 1978-04-14
Abstract: PURPOSE: To reduce vibration considerably and enlarge the shaving area by installing projected driving bushings connected to a pair of inner bodies at both sides of a driving element which can be bent into parallelogram.  
     CONSTITUTION: When motor 2 is driven, body 6 of a driving element 5 is vibrated by means of eccentric shaft 3 of eccentric cam 4. In this case, since pins 10 of body 6 are supported by holding parts 11 of housing 1, the driving element is bent in parallelogram, when eccentric shaft 3 is rotated in shaft receiving part 8, and one side of body 6 is reciprocated and the other side in the opposite direction. Therefore, each inner blade body 13 connected with driving bushing 9 is driven in largely reduced condition of vibration due to driving force of inner blade body 13 and its reaction force and due to the force of pins 10 in the opposite direction. Also, since a single motor can drive a pair of inner blade bodies 13 at the same time, shaving area will actually be doubled.

IPC: G01N37/00
Filed: 1991-03-11
Abstract: PURPOSE:To achieve a highly reliable and high-resolution measurement by using a whisker for at least one portion of a probe. CONSTITUTION:A whisker probe 1, where a tip portion is sharp and there is nearly no transformation due to a single crystal and strength is extremely large, is mounted to a drive portion 3 and a sample 2 is placed on a vibration- proof stand 4 below the probe 1. The probe tip is brought closer to the sample surface by a rough-movement mechanism in vertical direction. Further, it is brought closer to a distance where a tunnel current flows by the drive portion 3. While the whisker probe 1 is controlled in Z direction by a tunnel current amplifier 5 and a vertical direction control circuit 6 so that the tunnel current is constant, scanning is performed by a surface scanning circuit 7. The obtained measurement result passes through an input/output circuit 8, is processed by a microcomputer 9, and then is output to an image display device 10, thus achieving a highly reliable and high-resolution measurement.
