摘要:
Upon recording, a clearance control unit performs preheating by an added control value (BR) of a base heater control value B and an adjustment heater control value R and switches that to value B when it reaches a target sector to perform write. Upon reproduction, preheating is performed by the value (BR) and the value (BR) is maintained when it reaches a target sector to perform read. A correction processing unit detects contact between the head and a medium surface while increasing the value R from a predetermined initial value Ro, and sets a new calculated base heater control value B, and value Ro as the adjustment heater control value R. Write assist adjustment in which the measured adjustment heater control value R is adjusted to a heater control value that improves characteristic deterioration immediately after recording is started wherein preheating is switched to write heating is performed.

A laminated film structure, method of manufacturing, and a preferable electronic element using the structure. The effective polarization into the electric field can be realized in the direction of crystal axis by enhancing the crystal property and alignment property of the ferroelectric substance film formed through epitaxial growth with reference to the plane alignment of semiconductor substrate. After the yttrium stabilized zirconium film and a film of the rock salt structure are sequentially formed with epitaxial growth on a semiconductor substrate, the ferroelectric substance film of simple Perovskite structure is also formed with epitaxial growth. The ferroelectric substance film can improve the crystal property and alignment property thereof by rotating the plane for 45 degrees within the plane for the crystal axis of the yttrium stabilized zirconium.

Data comprising a pulse signal is divided into predetermined data segments. The number of pulse-signal fluctuations in the data segment is counted. A transmitter transmits the unchanged data to a receiving portion in a case where the number of pulse-signal fluctuations does not exceed a predetermined number. On the other hand, in a case where the number of pulse-signal fluctuations exceeds the predetermined number, the pulse signal is converted so as to be unchanged at the fluctuation of the pulse signal but to be fluctuated when the pulse signal does not fluctuate. Then, the transmitter transmits the converted pulse signal to the receiving portion wherein only the converted pulse signal is converted to the original pulse signal.

摘要:
There is provided not only a radio frequency power amplifier using an SiGe HBT subject to a little amplification distortion, but also a communication system using the same. A conventional radio frequency power amplifier provides base bias paths of transistors Q1 through QN (SiGe HBT) with bias resistors R11 through R1N having resistance values three to five times higher than those of a ballast resistor attached to each transistor's base. A coil LB is provided in parallel with the bias resistor as a means for compensating a voltage drop due to direct current component IDC flowing through the bias resistor. Addition of the bias resistor suppresses non-linearity of low-frequency variations in an output current. Addition of the coil compensates for voltage drop. Accordingly, the maximum linear output power can be improved. As a result, it is possible to provide the power amplifier subject to a little amplification distortion within a wide output range.

An induction heating cooker includes an induction heating unit having an induction heating coil, a top plate made of a glass and mounted over the induction heating unit so that an object to be heated is placed on the top plate, and a light-emitting display section formed in the top plate for displaying an output state of the induction heating unit. The light-emitting display section includes a light-emitting element disposed below the top plate, and the top plate includes a portion corresponding at least to the induction heating coil and the light-emitting element. The portion is coated with a light transmissible thin film including a semiconductor, metal or metallic oxide and having such a light-transmittance characteristic that light emitted by the light-emitting element is viewed above the top plate.
