Title: Method for measuring surface potential, method for measuring surface potential and surface shape, apparatus for measuring surface potential, and, apparatus for measuring surface potential and surface shape
Inventor: TOYOSHIMA NOBUAKI
IPC: G01R29/14
Filed: 1994-10-25
Abstract: PURPOSE: To measure the surface potential of an object with high space resolution. CONSTITUTION: A surface potential sensor 21 which has a material 24 with an electrooptic effect disposed between a dielectric reflecting film 23 and a transparent conductive film 22 is used. A DC bias potential and an alternating potential are applied to the transparent conductive film 22, and the light from a light source 31 is brought into the surface potential sensor 21. The change in the polarization state of the projecting light is converted to a light intensity signal by an analyzer 30 and synchronously detected with a frequency of the alternating potential. The DC bias potential is feed-back controlled by the detected signal and detected, whereby a surface potential signal is obtained.

Abstract: PURPOSE: To provide a toothbrush with improved polishing effect by combining a bristle-planted brush part to a handle part via a reciprocation mechanism to cause the brush part to be effectively in contact with the teeth arrangement curve and gums and the bristle tips to easily reach a space between teeth and a hollow of dental caries. CONSTITUTION: A brush hair part 1 to which brush hair 4 is planted, a connection body 2 formed by bending a wire rod, and a handle part to hold the end of the connection body inserted are constructed. A recess with a taper face 5 and a shaft hole to which a reciprocation shaft 7 of the connection body is inserted are constructed on the back side of the brush part 1. The tip part of the connection body 2 is rectangularly bent to form the reciprocation shaft 7 and the middle part is bent in a chevron shape corresponding to the reciprocation angle of the brush part 1. An inserting hole 10 to accept the rear part of the connection body 2 and a lateral direction small hole 11 are constructed on the handle part 3. Since the brush part 1 can be reciprocated within a reciprocation angle θlimited by the taper face 5, the brush face can rub the teeth arrangement in tight contact.
