Magnetic recording media-are provided having separately textured data and read/write head landing zones. Separating these zones on the recording surface allows independent optimization of the topology to maximize both recording characteristics and mechanical durability. The landing or contact start stop zone has an average surface roughness greater than that of the data zone. Preferably, a transition zone extends between the contact start stop zone and the data zone, the transition zone varying between the two in average surface roughness. Preferably, the contact start stop zone is textured first, followed by the data zone, thereby ensuring uniform stiction performance. Texture machines for producing such zone texturing and texturing methods are also provided.

Zone textured magnetic recording media and methods for their production

The controller of power supplying apparatus, upon outputting of a timing signal from a timer, brings a switching element, which is in the conductive state, into the non-conductive state and, in the meantime, brings a switching element, which is in the non-conductive state, into an intermittently conductive state until a NAND circuit stops outputting a short-circuit preventing signal and, thereafter, holds the switching element in the conductive state.

In order to realize the object of the present invention, which is to provide a noise detection circuit which is capable of coping with any pulse width of noise, and also of properly detecting the noise pulses which are consecutively generated, the noise detection circuit comprises a level monitoring circuit for monitoring the logic level of a signal input to a peripheral circuit within a microcomputer that needs to receive an input signal having a logic high level constantly for a certain period; wherein the level monitoring circuit further comprises a NOT circuit that inverts the polarity of a level monitoring signal input from the peripheral device for determining a signal level monitoring period, and an OR circuit that performs an OR operation between the output from the NOT circuit and the signal input to the peripheral device.

A microcomputer has a timer register 10 for storing period data of a carrier, timer registers 4A and 4B for individually storing positive phase and negative phase time width data of a control signal which is synchronized with the carrier, and an operation unit 13 for subtracting the value of the positive phase time width data of the control signal from a value of the period data. The time width data obtained as a subtraction result is supplied to the timer register 4B. The load on the CPU when the revolution of an induction motor is controlled is reduced.

A filtrating apparatus is disclosed in which a filter unit and a washing unit for effecting a fluid washing are unified into one system. A plurality of filter elements of main filters provided in the filter unit are made of sintered material containing metallic fiber. A nominal filtration rating of the filter elements is greater than 0.3 .mu.m but smaller than 2 .mu.m. Accordingly, it is possible to ensure the smooth filtration of beer funguses without any necessity of interchanging filter elements. It is therefore possible to reduce a running cost and filtration cost and to save a space for the apparatus.
