Title: Position detector
Inventor: TAMARU EIJI
IPC: G06F3/0488
Filed: 1983-12-12
Abstract: PURPOSE:To obtain a correct position detecting output at all times by making a time data counted by a count circuit ineffective when a level of a noise component of a detected output signal from a voltage detecting means is a prescribed level or over. CONSTITUTION:A data comparison circuit 103 compares a data Dz from a counter 102 with a reference data Dr at a period of a data discriminating pulse P and a comparison output Sco is obtained.

Title: Reciprocating mechanism for turning of arm
Inventor: INOUE MITSUGI
IPC: B21D43/05
Filed: 1989-09-08
Abstract: PURPOSE:To turn an arm at constant and high speeds shocklessly by providing a load uniformalizing mechanism to deny automatically and continuously the rotation moment based on the arm gravity/the weight of a functional tool. CONSTITUTION:At the time when an arm 72 is turned by a certain angle, a 1st link bar 101 in a load uniformalizing mechanism 100 is also turned concentrically just as its phase shifting by the same angle in the same direction. On the other hand, a 2nd link bar 103 is telescopicalbe, the tip part is supported with its rotation on the tip part of the 1st link bar 103 and the base end part is rotatably supported on the axial line which passes through the rotation center of the arm 72. Also, an energizing means 106 energizes the 1st link bar so as to apply an external force on the tip of the 1st link bar 101. Consequently, the rotation moment based on the arm gravity, etc., is denied while the arm is turned from the horizontal state to the vertical state and the load moment of a driving source becomes minimum and uniform. The arm is therefore reciprocated with its turning without shock at constant speed and high speed.
