A method and apparatus for detecting an abnormal fly height of a magnetic head. The method includes reproducing a servo signal recorded on a magnetic disk in advance by the magnetic head when a write operation for writing data on the magnetic disk by the magnetic head is initiated. Next, the gain of the servo signal based on the head part of the servo signal reproduced by the magnetic head is determined. The gain of the servo signal is then compared with a reference value to detect an abnormal fly height of the magnetic head. In an advantageous embodiment, the reference value is the gain of a servo signal determined when the fly height of the magnetic head is normal. Alternatively, in other advantageous embodiments, the reference value is based on the gain of a previous servo signal.

A drive unit which recovers from write instability by heating the magnetic head prior to performing a dummy write operation is described. In the preferred embodiments, once write instability has been detected the head may be heated by friction with the rotating disk or by an external heater. In the friction method the head is moved to a safe area of the disk such as a textured landing zone while the disk rotation is continued. In drives using unload ramps, a heater is preferably placed at the the ramp so that the head can be heated while parked on the ramp. In each of these embodiments dummy write operations are performed while the head is in a thermally excited state due to the heating. The combination of heating and the dummy write operation aids in restoring write stability.

A road surface condition detector for detecting a dry/wet condition of a road surface includes an ultrasonic wave receiver 2 for picking up the ultrasonic noise generated by a road wheel tire 1, which increases conspicuously when the R is wet. The output of the ultrasonic wave receiver 2 is amplified by a amplifier 21, and the absolute level thereof is detected by an absolute level detector 22, and the absolute level is smoothed by a received-wave intensity detector 20. The smoothed signal is compared with a reference voltage Vt to determine the road surface condition. Preferably, the reference voltage Vt is varied in accordance with the vehicle speed. When the automotive vehicle is provided with ultrasonic wave transmitter/receiver units 3a and 3b, the ultrasonic noise component is extracted from the received signal by an ultrasonic noise intensity detector circuit 40, and the extracted component is compared with a reference voltage level to determine the road surface condition.

It is an object of the present invention to provide a method which is capable of reducing a crushing rate of grain when the grain such as rice is transported by means of gas through pipes. The temperature of the grain in a grain accommodation tank which is connected to a transportation pipe for grain is measured. A temperature signal indicating this temperature is sent to control means, which determines the temperature of transportation gas so that a difference between this temperature and the temperature of the grain is within a predetermined range. The determined temperature is transmitted to an intercooler so that the temperature of the transportation gas which is sent from a blower and flows through the transportation pipe is controlled to be at the determined specific temperature. Transportation of the grain by means of the transportation gas at this temperature prevents the grain from crushing.

The present invention provides a method for detection of a vacuum leak of a vacuum vessel provided in an equipment, for example, an absorption chiller, and in which water and a solution (for example, lithium bromide solution) are charged. The gas in the vacuum vessel is purged by an auxiliary air pump while spraying helium as trace gas by a helium spray gun to the outer surface of the vacuum vessel under inspection of the absorption chiller, a part of the purged gas is passed through a dehumidifier where the steam is removed from the gas, a part of the purged gas is depressurized by reducing the partial pressure of the steam to zero, and it is detected by a helium-leak detector whether or not the trace gas (helium) leaks from the vacuum vessel. This method and an apparatus for carrying out the method permit to check for any vacuum leak and quantitatively determine it quickly, easily and with a high sensitivity whether the equipment under inspection is in or out of operation.

It is an object of the present invention to provide a changeover valve which is capable of preventing granular material from being crushed when the granular material is transported by gas through a pipe system, and more particularly a changeover valve which is capable of preventing grain from being crushed, broken, and chipped when the grain such as rice is transported by gas through the pipe system. It is another object of the present invention to provide a gas transportation pipe system for grain to which the changeover valve is applied. The changeover valve according to the present invention comprises: a valve disc in a cylinder shape including on a side part thereof a through passage which is connected to transportation passages on an upstream side and a downstream side and which is in an eccentric position deviated from a center of the cylinder; a casing for rotatably accommodating the valve disc therein; and a pair of discharge passages which are provided in the casing and connected to the through passage of the valve disc, and an inside diameter of an introducing passage of the changeover valve at an output end thereof is smaller than an inside diameter of the through passage of the valve disc and an inside diameter of the introducing passage in an output side part has a shape gradually decreasing in size toward the downstream side while an inside diameter of each of the pair of the discharge passages at an input end thereof is larger than the inside diameter of the through passage of the valve disc and an inside diameter of each of the pair of the discharge passages in an input side part has al shape gradually increasing in size toward the upstream side.

A disk drive with the capability to prevent off-track writing with reduced false triggering is described. An improved method of predicting the position of a head is used to determine whether the head is on or off-track. A position error signal at an nth servo position Pn and a velocity Vn at the nth servo position (Vn=Pn−Pn−1) are calculated using values read at the nth and n−1 head positions. Based on these Pn and Vn and on the output of the servo controller at the nth servo position Un, the predicted PESn+1 is calculated as: Predicted PESn+1=Pn+Vn+kUn where k is a constant. Data is inhibited from being written between the nth servo position and the (n+1) servo position, when absolute values of the calculated Pn, Vn, and predicted PESn+1 meet any condition of the following conditions (1) through (3): (1) |Pn|>C1, (2) |Vn|>C2, and (3) |Predicted PESn+1>C3 where C1, C2, and C3 are constants determined for the embodiment.
