Abstract: PURPOSE:To detect accurately a time point at an instant when a coating film is broken, by using a big difference created in a resistance value between a substrate and a head depending upon whether a magnetic layer is present on the substrate or not. CONSTITUTION:A resistor 2 is connected with a head arm 1, an electrical voltage is applied between another and of this resistor 2, and a spindle 3 and recorder are connected with both ends of the resistor 2. When a coating film remains not broken, no current is allowed between head 1 and spindle 3 and so, no voltage is produced on both ends of the resistor 2. Upon breakage of the film, the current is admitted for generation of voltages, (V) on both ends of the resistor 2. For instance, the applied voltage E is of 10V and resistor R of 43KOMEGA, a shown voltage change is observed. By detecting the voltage change on both ends of the resistor 2 with a differentiating circuit etc., the very instant D of the coating film can be defected.

Abstract: PURPOSE:To weaken a loading force and improve the starting torque efficiency of a motor by making a pressure area on the reverse side of a bush at the side of a gear continuous to a corresponding gear space, and forming a flow passage for connecting the pressure area to the low pressure side. CONSTITUTION:When a pressurized fluid has been introduced to a port 31, the concerned motor rotates and a fluid within a gear space is thereby discharged from a communication passage 24. In this case, a high-pressure fluid flows from the port 31 to a pressure area 23, a pressurized fluid within the gear space from clearances delta1 and delta2 to pressure areas 24 and 26 and a low- pressure fluid from a communication passage 34 to a pressure area 25, respectively. And when an electromagnetic valve V2 has made an ON/OFF operation in starting a motor, the pressure areas 24 and 26 become continuous to the low-pressure side via the electromagnetic valve V2, the communication passage 34 and the like, and a pressure level drops in the pressure areas 24 and 26 due to the throttle effect of the clearances delta1 and delta2. As a result, a loading force is weakened and starting torque efficiency is improved.
