摘要:
A dry etching method including the steps of introducing etching and deposition gases alternately into a reaction chamber at predetermined time intervals, etching the exposed surface of an article to be etched and applying deposition to the surface film thereof alternately by making plasma generated by applying power to the etching and deposition gases introduced into the reaction chamber come in contact with the article to be etched in the reaction chamber in order to etch the surface, is characterized in that the power is applied after the passage of predetermined time from the start of the introduction of the deposition gas and before the etching gas is introduced and cut off when the introduction of the etching gas is suspended.

A four-wheel steering system in a wheeled vehicle includes a lateral control shaft operatively connected at its opposite ends with a set of rear steerable road wheels, and a rear-wheel steering mechanism operatively connected to a front-wheel steering linkage for effecting axial displacement of the control shaft in response to operation of the front-wheel steering linkage. In the rear-wheel steering mechanism, a hydraulic power cylinder is adapted to control axial displacement of the control shaft in such a manner that the control shaft is returned to and retained in a neutral position in the occurrence of unexpected trouble in a hydraulic control circuit of the power cylinder to retain the rear road wheels in their neutral positions.

An apparatus for recording a color video signal in which a luminance signal and a chrominance signal are recorded on separate channels and at least two chrominance component signals are compressed in timebase and alternately arranged in turn to be recorded on one track as the chrominance signal is disclosed. This apparatus includes timebase compressing and expanding circuits provided respectively for the chrominance component signals and for producing timebase compressed chrominance component signals by writing the chrominance component signals by a first signal and by reading them by a second signal with the frequency integer times as high as that of the first signal and a coupling circuit for simultaneously supplying the chrominance component signals, which are being read out from the output terminals of the timebase compressing and expanding circuits by the second signal, to the input terminals of the timebase compressing and expanding circuits, whereby the timebase compressed chrominance component signals are written in the timebase compressing and expanding circuits by the second signal. In this case, when succeeding chrominance component signals are written in the timebase compressing and expanding circuits by the first signal, the timebase compressed chrominance component signals rewritten in the timebase compressing and expanding circuits are read out therefrom by the first signal so as to produce normal chrominance component signals.

An autochanger type optical compact disc player includes a tray for holding a large number of discs in close proximity, a disc selection mechanism for selecting a disc from the tray, a disc port for entering a disc from the outside of the player, a disc playback mechanism for playing a disc, a first loading mechanism for transferring a selected disc from the tray to the disc playback mechanism, a second disc loading mechanism for transferring a disc from the port to the disc playback mechanism, an unloading mechanism for selectively returning a disc to the tray or to the port, and a control section for controlling operations of the player. A disc is returned from the tray by a roller for contacting the edge of the disc during movement through a limited arc to impart rotational force to the disc.

Gas adsorbent and process for producing same. A zeolitic or silica-alumina adsorbent is heat treated in a carbon atom-containing gas or a gaseous mixture consisting of a carbon atom-containing gas and an inorganic gas at 100.degree. to 700.degree. C. to produce the gas adsorbent. The gas adsorbent has carbon particles ranging in size from about 0.01 to about 10 .mu.m adhering on the surface or in pores thereof.

A steering system includes a steering column which supports rotatably a steering shaft to which a steering wheel is connected and a pair of support mechanisms which support the steering column so as to tilt relative to a vehicle body. Each of the support mechanisms includes a support bracket having a column-side fastened portion and a body-side fastened portion, a fulcrum bolt, and a bush. A fastening hole through which a fastening bolt is inserted to fasten the support bracket to a fixed member is formed in the body-side fastened portion. Each of the support mechanisms includes an elastic member which can be compressed in an axial direction of the fulcrum bolt, and the support bracket is configured to oscillate relative to the steering column by the elastic member being compressed.
