A polyurethane composition containing solid beads dispersed therein, is formed of a microcellular polyurethane foam, and the composition has a storage modulus of elasticity at 40° C. of 270 MPa or more as measured by means of a dynamic elasticity measuring device. Another polyurethane composition of this invention contains solid beads dispersed therein, that are capable of swelling with or are soluble in an aqueous medium. The former composition has excellent flattening capability, and the latter composition can provide a polished surface which combines good flatness and good uniformity and can also reduce scratches on the surface.

摘要:
A method and an apparatus for recording and playing back monitored video data for recording monitored video data generated continuously for a long time on a magnetic tape, with less S/N degradation by shortening the operation time of the VTR to suppress the degradation of the magnetic tape, recording head, and other mechanical items. Video signals from a video camera are converted to digital signals in an A/D converter, compressed and encoded in a compression encoder and decoder circuit, then transferred to a time axis compression circuit which includes a first memory, the second memory, an SCSI controller, and a hard disk unit. The digital signal is thereafter compressed on the time axis and recorded on the magnetic tape loaded in a D-VHS standard VTR via an I/F circuit. Compressing the video data from the compression encoder and decoder circuit on the time axis in the time axis compression circuit makes the recording time of the video data shorter on the magnetic tape than the actual recording time of the video camera. The VTR is only required to record video data intermittently on the magnetic tape and a general home VTR can be adopted as the above VTR, this also prevents the magnetic tape from being damaged.

A magnetic recording/reproducing apparatus equipped with an image sensor includes a camera portion having an A/D converter for converting a signal from an image sensor into a digital signal and a first digital processor for receiving an output of said A/D converter and for digitally processing thereof. A VTR portion of a helical scan type mounts at least two or more of magnetic heads for recording/reproducing a FM modulated luminance signal and a low band converted chrominance signal. A second digital processor processes a video signal of the VTR. A switching circuit is provided in a preceding state of said A/D converter. The signal from the image sensor, an external video signal and a reproduced signal from the magnetic heads are exchanged. The output of the A/D converter is inputted to the second digital processor, and a sampling clock of said A/D converter is exchanged to most profitable clock for the signal from said image sensor, the external video signal and the reproduced signal from the magnetic heads, respectively.

A thin film forming apparatus using a laser includes a chamber (1), a target (5) placed therein, a laser light source (10) for emitting a laser beam to target 5, and a substrate holder (3). When the target is irradiated with a laser beam, a plume (15) is generated, and materials included in plume 15 are deposited on the surface of a substrate (2) held by the substrate holder (3). A magnetic field is generated to direct the plume. The magnetic field can be parallel to the surface of the substrate or in another embodiment a cusp magnetic field can be used (see FIG. 130).

A video signal is recorded in successive tracks on a recording medium together with a pilot signal, the latter having a frequency that changes cyclically with a different one of at least four frequencies in successive tracks. A field detector detects sequential fields in the frames of the video signal, and rotation of the usual rotary transducers is servo-controlled in response to the detected sequence of fields and a pulse that is generated as the transducers rotate to represent the rotational phase of those transducers. A pilot signal generator generates the pilot signal with an initial frequency determined by an initial field in the detected field sequence, and with this frequency changing as a function of the detected sequential fields.
