摘要： The controller circuit is designed to generate the positioning control signal based on the positional deviation of the head from a target recording track on a recording medium. A feedback control is effected to position the head right on a trajectory corresponding to the target recording track based on the generated positioning control signal. The positioning control signal is subjected to filtering at a notch filter. The cutoff frequency of the notch filter is set depending on the temperature detected at a thermal sensor. Even when the resonant frequency shifts in response to variation in temperature, the cutoff frequency of the notch filter follows the shift of the resonant frequency. A narrower bandwidth of the cutoff frequency still achieves reduction in the amplitude of the frequency component corresponding to the resonant frequency. The resonance or continuous vibration can reliably be prevented in the head. A rapid response can be accomplished in positioning the head right on a trajectory corresponding to the target recording track because of a narrower bandwidth of the cutoff frequency.

摘要： A strip of paperboard material having a thickness of 170 to 600 .mu.m and a multiplicity of fold lines formed widthwise thereof at a predetermined spacing and U-shaped in cross section is caused to travel as reeved around two prefolding rolls, 5 to 30 mm in diameter, from different directions at a contact angle of 40 to 270 degrees to bring the projecting side of the fold lines into contact with the peripheral suface of one of the rolls and the indented side of the fold lines with the peripheral surface of the other roll. This method imparts increased foldability to the fold lines.

摘要： A method and apparatus measures thermal conductivity of a material effected by measuring a change in the temperature of the material in contact with a heat source maintained at a predetermined temperature. A temperature change characteristic is obtained from the result of the temperature measurement, and the thermal conductivity is obtained by comparison of the temperature change characteristic and unsteady heat transfer characteristics of solid bodies previously determined in consideration of the heat transfer resistance of the interfaces. The present invention is suitable for the measurement of extensive materials, metallic materials to heat insulating materials, specifically suitable for the measurement of materials of high thermal conductivity and heterogeneous or anisotropic and is capable of accurately measuring the thermal conductivity without any special consideration on the interface heat transfer resistance at the measurement stage.

摘要： A heat exchanger comprises a plurality of regularly corrugated fins placed one over another in layers at regular pitches in a back-to-back arrangement so as to form alternate wide and narrow fluid passage between the adjacent corrugated fins, and each having a plurality of small through holes, a plurality of collars formed in a staggered arrangement, and an annular area not having any small through hole and formed so as to surround the root of each collar; and pipes for passing a secondary fluid therethrough, each inserted through the collars of the layers of the corrugated fins. The height of the collar from the lower surface of the annular area corresponds to the pitch between the adjacent corrugated fins, and thereby the corrugated fins can be assembled at regular pitches simply by placing one over another. The pipes are expanded after being inserted through the collars so that the pipes are firmly and closely joined to the collars for satisfactory heat transmission between the fins and the pipes.

摘要： A mechanism for controlling the flow of air from an air-conditioning unit includes a row of guide vanes which are pivotally held by an outlet nozzle. The guide vanes are located at the lower end of an air course which has been formed within a body of the air-conditioning unit. The guide vanes control the flow of air in both left and right directions. This new design is characterized in that the angle of inclination of each guide vane progressively changes toward the end of the row. The air flow is controlled accurately in both the left and right directions so that the air flow reaches the desired location.
