Abstract: A tracking error detector circuit to maintain correct disk tracking on high density disks is provided within an apparatus for playing a prerecorded disk (1). The disk (1) contains two carrier signals with frequencies f₁ and f₂, which are alternately superimposed onto an information signal each rotation of the disk (1). The tracking error detection circuit includes circuitry (24-33) to determine, as a first error signal (f₁TE), the difference in amplitude between the f₁ frequency components of the tracking sub-beams (S A ,S B ) and, as a second error signal (f₂TE), the difference in amplitude between f₂ frequency components of the tracking sub-beams (S A ,S B ). The detection circuit further includes means (35-40) to detect one rotation of the disk (1) and means (34) for alternately selecting the first and second error signals each time the rotation sensor detects a disk revolution. This selected error signal acts as the tracking error signal (TE) for the succeeding revolution of the disk.

Abstract: A method of managing beams transmitted and received by a plurality of phased array antennas. In a search mode, the phased array antennas transmit searching pulses synchronously in a search mode. In a tracking mode, targets tracked by the phased array antennas are divided to a plurality of groups on the basis of pulse repetition rate. Then, for the respective divided groups, transmission timings of tracking pulses to be sent from the phased array antennas are calculated by using ranges of the targets belonging to the respective groups so that transmission and reception operations do not occur simultaneously, thereby enabling the simultaneous usage of the phased array antennas.

Abstract: A charged particle beam apparatus comprising at least a charged particle source and an objective lens for converging onto a sample a charged particle beam emitted by the charged particle source. The objective lens is an electrostatic objective lens constituted by a first and a second electrode positioned opposite to each other and having openings through which the charged particle beam passes. The first electrode and the second electrode are located close to the charged particle source and to the sample, respectively. The first electrode is supplied with a positive potential as opposed to the second electrode when the charged particle beam is a negatively charged particle beam. Conversely, the first electrode is supplied with a negative potential as opposed to the second electrode when the charged particle beam is a positively charged particle beam. The principal plane of the electrostatic objective lens is located on the side of the sample below the bottom plane of the second electrode. This constitution allows the apparatus to be very small in size and to provide high resolution for observation.

Abstract: This invention aims at providing an high output FET having a planar type-gate structure suitable for integration, and a structure that suppresses long gate effect. A heavily doped thin channel layer 13 is formed on a semiconductor substrate 11, and a cap layer including a doped layer 15 is formed on the channel layer 13. A thickness and a dopant concentration of the doped layer 15 are so set that the doped layer 15 per se is depleted by a surface depletion region resulting from an interface level of the semiconductor substrate surface, and the surface depletion region does not widen to the channel layer 13. Consequently no long gate effect takes place on the side where a gate bias is lower.

Abstract: The present applicants have discovered that a layer predominantly comprising tungsten can be formed into precise patterns having substantially vertical walls by using titanium as a mask and plasma etching in a fluorine-containing plasma such as CF₄ or SF₆. The success of the process is believed attributable to the occurrence of an etch stop reaction on the sidewalls of the tungsten. The products of the reaction inhibit horizontal etching. After the tungsten is etched, the titanium mask can be selectively removed, as by etching in dilute HF. Each step in the process can be effected without subjecting the workpiece to voltage magnitudes in excess of 200 volts or temperatures outside the range between room temperature and 200°C.
