摘要： PROBLEM TO BE SOLVED: To improve the forming rate of a thin semiconductor film and the uniformity of the grown thickness of the film. SOLUTION: In a method of manufacturing thin semiconductor film, thin semiconductor films are respectively grown on a plurality of substrates by dipping the substrates in a crucible filled up with a solution containing a semiconductor as a solute and moving the substrates in the solution. In the method, a flow of the solution is formed by moving the substrates in the directions which are deflected from the directions of normal lines to the central parts of the growing surfaces of the substrates by 5-87 deg.. Alternatively, the flow of the solution is formed without generating any substantial eddy current in the vicinities of the growing surfaces of the substrates by moving the substrates in the directions which are deflected from the normal lines by 93-175 deg..

摘要： PURPOSE:To enable a high precision tracking control as well as high density recording by recording time-divisionally a main signal and a nonsignal in each track and performing the tracking control based on every other pilot signal in a nonsignal area a the time of reproducing. CONSTITUTION:When a tape is traveled in the direction of A, while a rotary head having heads H1 and H2 is rotated in the direction of B, each track is time-divisionally recorded with the main signal (PCM) and the nonsignal (ATF), and at the same time, the pilot signal f1 a single frequency is recorded to every other track in an intermediate part of the ATF area. The signal f1 is sampled from a signal regenerated from a head for dealing with a track, which is not recorded with the signal f1 at the time of reproducing, as a home track and synchronized with an output from a sampling pulse generating circuit 46, and then a cross talk amt. is subject to sample and hold by sample-and-hold circuits 44 and 45, so that the tape 30 is controlled in its movement by a servo circuit 50 in order to equalize this difference.

摘要： PROBLEM TO BE SOLVED: To provide an isolation method of a semiconductor layer, where strong sticking can be obtained in an isolating process and the following process is facilitated, e.g. detachement from a holding member is readily enabled, and a manufacturing method of a solar battery which uses the isolating method. SOLUTION: A substrate, having an isolating layer 2 between a semiconductor layer 4 and a semiconductor substrate 1, is prepared (a). A side surface opposite to the isolating layer 2 of the semiconductor substrate 1 is held with an ice layer 14, where water spreads thinly between the semiconductor substrate 1, and a retaining table 15 as a holding means is cooled (b). The semiconductor layer 4 is isolated from the semiconductor substrate 1 by using the isolating layer 2 (c). After that, the temperature is returned to room temperature, the ice layer 14 is melted, and the retaining table 15 and the semiconductor substrate 1 are isolated. The semiconductor substrate 1 is regenerated and put into a series of processes. The semiconductor layer 4 is used as a solar battery. Thereby a large number of solar battery units can be manufactured from the a single semiconductor substrate 1, so that this method contributes to cost reduction and the semiconductor layer can be isolated stably, without developing cracks or scratches.

摘要： PURPOSE:To apply pilot signals to the recording of a narrow track and high density by recording the pilot signals different in frequencies in adjacent tracks into restricted tracking-only areas and deciding the track deviation of the rotary head with crosstalk from the adjacent tracks at the time of reproduction. CONSTITUTION:Pilot singles f1 and f2 different in frequencies are alternately recorded in the recording areas (ATF part) of the pilot signals at every track, and the ATF areas of respective tracks are set to partially overlap with the ATF areas in the adjacent tracks. Since the pilot signal recording areas ATF are shifted in the longitudinal direction of the tracks, the crosstalk of the pilot signals from adjacent tracks on both sides are taken at mutually different timing. The other pilot signal is reproduced as crosstalk component from the adjacent tracks at first and second timings corresponding to the reproducing timing of the other pilot signal, and the direction and quantity of track deviation can be detected by the comparison of the reproduced levels. Thus, the pilot signals can be permitted to correspond to the recording of the narrow track and high density.
