Title: Flow control device
Inventor: ISHIKAWA NORIKAZU
IPC: F15D1/02
Filed: 1986-05-16
Abstract: PURPOSE:To obtain a flow control device which eliminates breakage and choking, by providing an airfoil partition plate having a round front end and a sharp rear end, and thereby permitting a smooth flow in one direction, while making a collide of flow in the reverse direction. CONSTITUTION:When a fluid flows from a gate 3 to a gate 4, the fluid flows through a branch passage 9 toward the gate 4, and a part of the fluid is inverted to flow through a branch passage 8 toward the gate 4. Then, both the flows join at a sharp end 6, and is discharged from the gate 4. On the contrary, a fluid flowing from the gate 4 is divided into the branch passages 8 and 9 toward the gate 3. The fluid in the branch passage 8 is inverted along a round end 5, and collides with the fluid in the branch passage 9, thus mutually obstructing the discharging of the fluid from the gate 3. Accordingly, the fluid flow in one direction is rendered smooth, and the fluid flow in the counter direction is restricted by the collision of flows, thereby reducing the flow rate and retarding the pressure transmission. Thus, the flow restriction may be simply carried out. Further, as no movable members are provided, there is no possibility of breakage and choking.

Title: Focus controller
Inventor: ASHINUMA TAKAAKI
IPC: G11B7/085
Filed: 1988-05-12
Abstract: PURPOSE:To prevent defective focus setting due to dispersion in the sensitivity of an actuator and mechanical accuracy from being generated by controlling the position of the actuator in a focusing direction by the signal of a D/A converter, and holding a value at the time of performing an operation. CONSTITUTION:When focus setting is performed, firstly, a loop switch 5 is connected to 2 side, and the loop of a whole system is cut. Then, data by which a focus actuator approaches gradually to a medium from a remote place is sent from a controller 4 to the D/A converter 6. Thereby, the switch 5 is switched to 1 side at the trailing edge of the next error signal after a sum signal is increased, and simultaneously, the value of the converter 6 is stopped to change, and the value is held until the next focus setting operation is performed. Therefore, it is possible to eliminate the defective focus setting due to the dispersion in the sensitivity of the actuator or the mechanical accuracy.
