Abstract: PROBLEM TO BE SOLVED: To make it possible to maintain a constant distance between a rotor magnet and a magnetic sensor regardless of the dimensional error of a rotor magnet in a motor having the configuration of opposite arrangement of a magnetic sensor at the end surface of a rotor magnet fixed to an inner peripheral surface of a cup shaped rotor case. SOLUTION: In a motor 1, a rotor magnet 10 is fixed to an inner peripheral surface 202 of a cup-shaped rotor case 20.

Title: Switch circuit
Inventor: HAYAZAKI SHINZOU
IPC: H03K17/96
Filed: 1977-12-02
Abstract: PURPOSE:To surely turn on or off a switch when a human body comes into contact with a touch plate even if the potential of the human body is equal to that of the ground, by applying a high control voltage to the switch. CONSTITUTION:The potential difference between a grounded part 9 of a television set 1 and a second input terminal 6 and the potential difference between the grounded part 9 and a first input terminal 5 is about a half of an input DC voltage E1.  The turnover voltage E2 is represented as E2 (sq. rt. 2 Ei)/2. Thus, the voltage E2 is directly applied to the touch plate 12a or 12b of the television set 1 when the human body of the same potential as the ground comes into contact with the touch plate 12a, or 12b. The effective voltage E1 of a power source 2 becomes lower than the turnover voltage E2. This means that the amplification degree of a transistor 10 is equivalently raised. The transistor 10 can be completely saturated even if the potential of the human body is equal to that of the ground.
