Filed: 1997-11-19
Abstract: PROBLEM TO BE SOLVED: To move and control a driving roller along a driving shaft lightly smoothly, and prevent movement along the driving shaft of the driving roller surely with a great force. SOLUTION: The driving roller 32 interlocks with a driving shaft 6 connected to an X motor in the rotation direction and is fitted therewith slidably along the longitudinal direction, and serves to hold paper through a mutual effect with a pinch roller 30. A compression base 14 is fitted and arranged shiftably with a compression shaft 8 being in parallel with the driving shaft 6 along therewith, and supports the driving roller 32 rotatably by preventing its axial direction movement thereof. A conical spring 51 is fitted in the compression shaft 8 slidably along the compression shaft 8, one side of a lock spring 51 is engaged to the eccentric part of a lock can 44, and the other side of the lock spring 51 is engaged to the side of the compression base 14.  When the compression shaft 8 is rotated for allowing the lock can 44 to rotate, a coil part of the lock spring 51 is contracted in diameter so that the coil part is clamped and fixed to the compression shaft 8, thereby permitting the compression base 14 to be locked in the compression shaft 8.

IPC: H04B1/10
Filed: 1993-12-28
Abstract: PURPOSE:To suppress noise due to omission of voice data by muting a voice output when a specific bit pattern (unique word) representing succession of valid data is not detected. CONSTITUTION:A signal demodulator 2 demodulates a digital signal from a radio wave received via an antenna system 1, a voice decoder 3 converts the digital signal into a voice analog signal and gives the analog signal to a speaker 4.

IPC: B28C7/00
Filed: 1987-12-28
Abstract: PURPOSE:To round off aggregates and consequently increase the strength of concrete by a method wherein the aggregates are dry-mixed in advance at the making of concrete by mixing cement with water, the aggregates and the like. CONSTITUTION:After cement, water, aggregates, which consist of fine and coarse aggregate and admixture are batched, the fine and the coarse aggregates charged into a mixer such as a two-shaft forced action mixer or the like so as to be dry-mixed. The dry mixing is done for about 40-90sec so as to rub the aggregates each other in order to wear off the corners and burrs of the aggregates and round off them. Further, fine particles and clay content adhering to the aggregate itself and the air film on the surface of the aggregate are rubbed off and removed. Accordingly, the adhesion between the aggregate and cement paste becomes very good, resulting in uniformly dispersing surface moisture and decreasing the amount of bleeding water.
