Abstract: PURPOSE:To make a cartridge holder move over all the strokes with nearly equal forces by using a curved groove whose slope gradually increases as the cartridge holder moves from a disk clamping position to a disk releasing position as a cam groove engaging with the pin of the cartridge holder. CONSTITUTION:As the cam groove 16A engaging with the pin 13 of the cartridge holder 12, the curved one whose slope gradually increases as the cartridge holder 12 moves from the disk clamping position to the disk releasing position is used. Therefore the slope of the cam groove 16A is small at the time of beginning to move an operational member 15 and the disk clamped with the strong attractive force of a magnet can be released with comparatively weak force. After that, since the attractive force of the magnet becomes weak powerful force is not needed. Thus, the operational member 15 can be made to move with nearly equal force and the cartridge holder 12 can be made to easily and smoothly move every stroke.

Title: Flexible wood fiberboard and manufacture thereof
Inventor: HIRAOKA AKINORI
IPC: B27N3/04
Filed: 1986-03-07
Abstract: PURPOSE:To obtain wood fiberboard with excellent flexibility by hot-pressing under specified conditions. CONSTITUTION:Wood fibers mixed with 3% and more by weight of solid matter of synthetic rubber latex is dried by being on air stream to 6-10% moisture content and laminated in the form of mats so as to be hot-pressed under the conditions of a pressure of 50-80kg/m<2> by flat plate press and of a heating temperature of 120-180 deg.C. Because split wood fibers are dried immediately after being covered with synthetic rubber latex in dry process in the state that the concentration of the latex contacting with the fibers is much higher than that by wet forming, the fibers, to the surface of which synthetic rubber adheres, are obtained. Consequently, a resultant hot-pressed fiberboard has the synthetic rubber uniformly distributed in layers among the fibers so as to fully contribute to give flexibility and impact absorbency to the fiberboard.
