A specific resistance value adjustment apparatus includes: a hollow fiber membrane module; a module passing pipe which passes through the hollow fiber membrane module; a bypassing pipe which bypasses the hollow fiber membrane module; a liquid discharge pipe which communicates with the module passing pipe and the bypassing pipe through a joint portion; a first flow rate detection unit which detects a first flow rate of a liquid flowing to at least one of a liquid supply pipe and the liquid discharge pipe; a control valve which opens and closes the module passing pipe; and a control unit which sets an opening degree of the control valve in response to the first flow rate detected by the first flow rate detection unit.

Resistivity adjustment device and resistivity adjustment method

A resistivity adjustment device includes: a hollow fiber membrane module that is divided by a hollow fiber membrane into a liquid phase side area; a liquid supply pipe that communicates with the liquid phase side area; a liquid discharge pipe that communicates with the liquid phase side area; a gas supply pipe that communicates with the gas phase side area; a gas discharge pipe that communicates with the gas phase side area; a bypass pipe that communicates with the liquid supply pipe and the liquid discharge pipe to bypass the hollow fiber membrane module; and a first on-off valve that is connected to the gas discharge pipe and opens or closes a first passage inside the gas discharge pipe, wherein the first on-off valve opens the first passage to discharge water accumulated in the gas phase side area.

Device for adjusting specific resistance value and method for adjusting specific resistance value

The present invention provides a device and a method for producing a magnetic recording medium having a lubricant membrane with a uniform thickness on a surface. The device for producing the magnetic recording medium includes: a hanger device that is inserted into the central hole of the magnetic recording medium and supports the magnetic recording medium in a hanging state; and a raising and lowering device that raises and lowers one of the hanging device and an immersion tank with respect to the other thereof. The hanger device includes a support plate of which an upper end comes into contact with an inner circumference of the magnetic recording medium and a liquid-cutting plate which extends from a lower end of the support plate and is distant by a space along the inner circumference of the magnetic recording medium from the inner circumference of the magnetic recording medium.

Method for producing and device for producing magnetic recording medium

Provided is a magnetic recording medium manufacturing apparatus capable of forming a lubricant film with a uniform thickness on the surface of a magnetic recording medium. The magnetic recording medium manufacturing apparatus includes a hanger mechanism () that is inserted into a central hole () of a magnetic recording medium () and supports the magnetic recording medium () in a suspended state and a lifting mechanism () that lifts and lowers one of the hanger mechanism () and the dip tank () relative to the other. The hanger mechanism () includes supporting plates () that have upper ends coming into contact with an inner circumferential portion of the magnetic recording medium () and baffle plates () that have upper ends disposed below the upper ends of the supporting plates () such that a gap is formed between the upper end of the baffle plate and the inner circumferential portion of the magnetic recording medium () and are provided so as to face the supporting plates ().
