Abstract: PROBLEM TO BE SOLVED: To provide an ultrasonic cleaning apparatus with a waterproof mechanism, capable of suppressing heat generation in an ultrasonic vibration part. SOLUTION: When the ultrasonic vibration part 14 is overloaded, a control to lower a power supply is conducted by an overload detection circuit 32 and an oscillation circuit 31. In this way, heat generation in the ultrasonic vibration part 14 can be prevented by detecting an overload state and reducing the amount of power supply. Thus, an ultrasonic cleaning apparatus that does not give unpleasant feeling to a user because heat generation is suppressed and gives an ease of handling to a user can be realized.

Abstract: PROBLEM TO BE SOLVED: To improve the electromagnetic conversion characteristics of a magnetic recording medium by assuring a coating application state free from the unevenness of coating at the time of coating on the magnetic recording medium. SOLUTION: In the process for producing the magnetic recording medium by allowing a supporting body 1 to travel and applying a coating material by an extrusion type die 10 on this supporting body 1, shearing force is applied to the coating material after final dilution before the coating material is supplied into the chamber in a die and the average stagnation time of the coating material after the application of this shearing force before the execution of the coating is so regulated as to be within the time when the change ratio ΔG'=|G'(t+Δt)/G'(t)|Δt from the modulus G'(t) of elasticity in storage at certain time (t) to the modulus G'(t+Δt) of elasticity in storage after the slight time Δt attains >=0.03.

Abstract: PROBLEM TO BE SOLVED: To sufficiently decrease uneven thickness of a coating film in the width direction of a support and to obtain good coating property by controlling a slot gap of an extrusion die to a specified value or smaller and controlling the flowing state of a coating material to have specified or smaller difference of the stress along a first normal line. SOLUTION: When a magnetic coating material flows, the network structure is stretched along the streamline of the flow, and tension T generates on the streamline. By forming a recess 61 in one side perpendicular to the flow in the passage of a supply tube 53 for the magnetic coating material, a passage 62 with curved streamlines of the magnetic coating material is formed. By disposing pressure meters 63A and 63B on both sides of the flow, the difference of the stress along the first normal line in this state is measured by the difference of the pressures by the pressure meters. To improve the quality of a magnetic recording medium, the slot gap of an extrusion die in the production line is controlled to .

Abstract: PROBLEM TO BE SOLVED: To ensure a coated state free from unevenness in coating a magnetic recording medium and to improve the electromagnetic transducing characteristics of the medium. SOLUTION: When a substrate 1 is allowed to run and coated with a coating material by means of an extrusion type die 10 to produce a magnetic recording medium, a shear is applied to a coating material before final dilution at >=100sec shear rate so that the product of the shear rate and shear application time is regulated to >=30,000 before the coating material is fed into a chamber in the die 10. The average retention time of the coating material from the application of the shear to coating is regulated to such a time or less as to regulate the variation in the modulus of storage elasticity in a very short time (Δt) calculated by the equation ΔG'=|G'(t+Δt)/G'(t)|/Δt to >=0.03. In the equation, G'(t) is the modulus of storage elasticity at a certain time (t) and G'(t+Δt) is the modulus of storage elasticity after the lapse of the time Δt from the time (t).
