Title: Tooth brush with diagonally cut bristle part
Inventor: SAKAIDA MAKOTO
IPC: A46B9/04
Filed: 1995-10-09
Abstract: PROBLEM TO BE SOLVED: To enable brushing of back teeth easily without causing a user to distort his mouth greatly sideways by arranging a diagonally cut bristle part of a tooth brush whose height is gradually lowered from the tip side to the rear side so that the grip of the tooth brush erects almost vertically to lips. SOLUTION: A diagonally cut trapezoidal bristle part 2 is so arranged on a planting base 1 of a tooth brush that the bristles longest on the first front row become evenly shorter backward one row by one row.

Abstract: PURPOSE:To obtain a tracking error signal where there is no offset by controlling the signal level of output components from four light receiving areas out of the outputs from two addition means with level detection signals according to the respective outputs from four division type light receiving element. CONSTITUTION:The level detection signals are generated according to the signal levels of the respective outputs from the four light receiving areas of the four division type light receiving element 1 and the signal level of the output components from four light receiving areas out of the outputs from two addition means 4 and 7, which respectively add the outputs from two pairs of the light receiving areas symmetrical concerning an intersecting point of two lines dividing the four division type light receiving element 1, is controlled with the level detection signals. The signal according to the phase difference of the outputs from two addition means 4 and 7 is generated as the tracking error signal. Therefore, the levels of the output components of the respective elements in two signals obtained by respectively adding the outputs from two pairs of symmetrical elements are equal each other even if the position of a light spot formed on the light receiving surface of the four division type light receiving element 1 is displaced. Thus, the phase difference between two signals does not alter and the occurrence of the offset of the tracking error signal can be prevented.
