In an apparatus of the kind arranged to reproduce, with a plurality of rotary heads, an information signal from a record bearing medium having many recording tracks which are parallel to each other with the information signal recorded therein and with a plurality of different pilot signals of different frequencies also recorded one by one, one in each of the recording tracks, a plurality of different reference signals of different frequencies are simultaneously generated. A tracking error is detected by using the different reference signals together with the pilot signals which are included in signals reproduced from the plurality of rotary heads.

In a zoom lens of a fixed total length, at the time of changing the magnification from the wide-angle end toward the telephoto end, the first lens group is anchored while the second lens group is moved, and the third and fourth lens groups are moved so as to be located at the object side of the telephoto end relative to the wide-angle end, such that: the interval between the second and third lens groups is decreased at the telephoto end relative to the wide-angle end; the interval between the third and fourth lens groups is increased at the telephoto end relative to the wide-angle end; and the interval between the fourth and fifth lens groups is increased at the telephoto end relative to the wide-angle end, and at the time of focusing a near object point from a remote object point, the second lens group is moved.

The present invention provides a protective cover structure for a rammer for which a guard cover plate of a power engine in a rammer is molded from a synthetic resin allowing any shape to be freely obtained and having small weight, high strength, and impact absorption ability. The cover plate is configured so that it can be assembled and disassembled by simple operations, has good endurance with respect to severe vibrations and can reduce the damage of the machine body due to the adequate impact absorption ability even when the rammer tumbles.Front end sections of guard covers disposed on both sides of a power engine are joined and fixed to the front surface section of the crank chamber, lower sections of the rear portions are supported by support frames of a protective stand provided at the lower surface of the power engine, and the rear sections of the rear portions are linked integrally by a linking transverse pole.

An image storage system for storing in a storage medium digital image data corresponding to an image. An object is imaged and the digital image data are stored in the storage medium according to either of a first storage mode, and a second storage mode, the second digital image data being supplied from outside the system. Thus, it becomes possible to efficiently store digital image data in a storage medium.

An information signal recording system arranged to divide original information signals into signal groups, each bearing a predetermined amount of information, to have a plurality of compressing modes for different information compressing ratios and to compress the information signals of each group in one of the different compressing ratios in recording these signals on a tape-shaped magnetic recording medium comprises first compressed information signal forming assembly which operates on all these groups to form and produce a first compressed information signal consisting of only the information signals of a specific part of each of these groups; second compressed information signal forming assembly which operates on some of these groups to form and produce a second compressed information signal consisting of information signals of each groups excluding the information signals of the specific part; a magnetic head which records signals on the tape-shaped magnetic recording medium by tracing the medium in a direction of crossing the longitudinal direction of the medium; and supply assembly for supplying the magnetic head with the first and second compressed information signals by switching them from one over to the other at every half of the medium tracing period of the magnetic head.
摘要:
In an image encoding apparatus, conversion data obtained by converting image information onto a frequency region, and corresponding to several frames are parallelly output using a one-frame-period delay circuit. The parallelly output conversion data are quantized by a quantization circuit, and a data amount to be obtained when the quantized data are encoded is obtained by a variable-length coding circuit. The data amount information is input to a coefficient operation circuit for determining a quantization step of the next stage. Conversion data quantized according to an output from the coefficient operation circuit are encoded, and the encoded data are output.
