Title: Controller of automatic speed change gear
Inventor: FUKUMURA KAGENORI
IPC: F16H61/16
Filed: 1984-05-04
Abstract: PURPOSE:To improve the durability of component parts by prohibiting a main speed change gear from becoming overdriven speed range while operating position for deciding speed range of a sub speed change gear remains in low speed range. CONSTITUTION:While the operating position for deciding speed range of a sub speed change gear 16 remains in low speed range, a main speed change gear 14 is prohibited from entering overdriven speed range. As a result, while the sub speed change gear 16 remains in low speed range, the main speed change gear 14 is kept away from entering overdriven speed range, hence, the maximum rotation speed of an output shaft of the main speed change gear 14 is limited to a proper value with the result that the durability of component parts of output shaft system of the main speed change gear 14 and input shaft system of the sub speed change gear 16 can be improved.

Title: Sublimating type thermal transfer recorder
Inventor: SAJI YOSHITO
IPC: B41J2/355
Filed: 1990-04-03
Abstract: PURPOSE:To enable recording to be performed by low energy by enlarging a dynamic range of recording density by a method wherein a maximum value of electrifying time to a heating element for forming one dot is specified, and a driving pulse of image receiving paper by a paper carrying means is generated just after ending electrification to the heating element.

Further, applicable energy to the heating element 3a is more effectively transmitted to ink. Furthermore, a development layer of image receiving paper 1 is effectively heated, and dynamic range of recording density is enlarged. A pulse motor 12 performs step operation slightly practically overshooting by a driving speed and a load. Therefore, recording is performed for short time of applicable pulse width tau=6msec or shorter, influence due to overshooting of paper carrying is decreased over all ranges of the applicable pulse width, and a stabilized recording density characteristic from low density to high density is obtained.
