A shaft cylinder having an opening at a front end thereof, a tip holder movable in an axial direction of the shaft cylinder, a tip projectable and retractable in conjunction with a movement of the tip holder, an annular member loosely fitted onto an inner periphery of the opening of the shaft cylinder to be movable in an axial direction of the shaft cylinder with respect to the shaft cylinder, and an elastic member capable of connecting the tip holder and the annular member such that the tip holder and the annular member are movable relatively to each other. A contact surface tapered toward the front end is formed on at least a part of an outer periphery of the annular member. A cutout is formed on the annular member such that an inner diameter of the annular member is reduced when a load is received by the contact surface.

Projectable and retractable writing tool

In a writing tool, a front shaftis detachably provided on a rear shaftcontaining an ink absorbent body. A filling partis provided on an outside surface of a rear part of the front shaft. The filling partdetachably fits to a fitted partformed on an inside surface of an opening part of the rear shaft. The filling parthas an outward-facing pressure contact partand a radially penetrating slit. The fitted parthas an inward-facing pressure contact part. The front shaftand the rear shaftare brought into a pressure contact with each other when the front shaftand the rear shaftare fitted to each other.

Writing tool

Disclosed is a litz wire coil that is configured by spirally winding a litz wire on one plane by a predetermined number of turns. The litz wire is configured by twisting together a plurality of enameled wires formed by baking an insulating film on a conducting body. Pressure shaping is performed such that the litz wire has a substantially rectangular shape in cross section, and the flatness ratio of the litz wire in cross section (long side/short side) is controlled at 1.10 to 1.60, preferably 1.20 to 1.40, more preferably 1.25 to 1.35.

Litz wire coil

A data recording and reproducing apparatus for recording and reproducing data on azimuth tracks of a magnetic tape in which the data may be audio data or computer data in any of several different computer data formats includes a controller that controls the recording and reproducing signal processing so as to be responsive to the four different kinds of data formats such that main data and subdata may be separated from the audio data and subcodes and error correction codes generated and appended to the data stream as required.

Digital audio tape recording/reproducing apparatus for use with multiple formats

An apparatus and method for recording digital data employing a DAT (digital audio tape recorder) adapted to record the data from a computer or the like in accordance with the DAT format, wherein a unit is formed of predetermined plural frames and a signal indicative of each frame number within a unit and a signal indicative of the last frame of the unit are recorded with each frame, whereby the length of the unit can be arbitrarily changed and accordingly signal processing is facilitated easily.

Apparatus and method for recording a digital signal

An apparatus and method for recording and/or reproducing digital data employing a DAT (digital audio tape recorder) adapted to record and/or reproduce data from a computer or the like in accordance with the DAT format. Main data is recorded in a main area of a track while error detecting data for the main data recorded in the main area of the track is recorded in a sub-area of the track to thereby easily detect an error in the main data.

Apparatus and method for recording and/or reproducing a digital signal

An apparatus and method for recording and/or reproducing digital data employing a DAT (digitial audio tape recorder) adapted to record and/or reproduce data from a computer or the like in accordance with the DAT format. Main data is recorded in a main area of a track while error detecting data for the main data recorded in the main area of the track is recorded in a sub-area of the track to thereby easily detect an error in the main data.
