Title: Head positioning control circuit
Inventor: HASEGAWA SUSUMU
IPC: G05D3/12
Filed: 1989-03-17
Abstract: PURPOSE:To improve head positioning accuracy by adding a signal to suppress disturbance due to the eccentricity of a disk on a position feedback loop system as a feedforward signal. CONSTITUTION:A switch SW2 is turned off and a switch SW3 is turned on when the phase of a sine wave from a sine wave generator 25 is decided by a sine wave phase adjusting circuit 23. At this time, a switch SW1 remains at an ON-state, and at such state, the gain of the generator 25 is decided so that the output of a peak value detection circuit 22 can be minimized similarly by a sine wave gain control circuit 24. When the gain of the sine wave generated once at the generator 25 is decided by the adjusting circuit 23, the gain remains unchanged until it is changed by the adjusting circuit 23 next. In other words, the optimum phase and gain of the feedforward signal in which the head positioning accuracy goes to the minimum level is decided, and hereafter, all the switches SW1-SW3 are turned off, and the feedforward signal having decided phase and gain is added on the system. In such a way, the head positioning accuracy can be improved.

Title: Electric discharge machining fluid
Inventor: YAMADA SHIGEO
IPC: B23H1/08
Filed: 1980-05-15
Abstract: PURPOSE:To accelerate the extinction of viscous bubbles generated during electric discharge machining by a method wherein antifoaming agent is added to the electric discharge machining fluid made up of the mixture of water and organic compound solution. CONSTITUTION:In the noninfammable electric discharge machining fluid mixed with water and an organic compound solution in a ratio so as not to burn itself, when the fluid with high viscosity is used, the viscous bubbles are generated and accumulated between electrodes for a time long enough to produce gaseous discharge and joined together to form bubbles large enough to ignite the inflammable gas in the large bubbles. In order to prevent the production of gaseous discharge and the ingition of the gas in the bubbles, the antifoaming agent is added to said machining fluid to prevent the bubbles from joining together with each other to form large bubbles, resulting in quickly discharging the bubbles from the space between the electrodes. Nonionic antifoaming agent is used. The amount of the agent to be added is set approximately to 0.1% or less of the electric discharge machining fluid by volume.
