Title: Apparatus and method for cutting
Inventor: OKADA TAIJI
IPC: B27C1/12
Filed: 1994-09-29
Abstract: PURPOSE: To prevent the interruption of working due to the stop of moving an object to be worked at the time of switching a mode by continuing the forward rotation of a forward/reverse rotation motor by a controller until at least one directional cutting operation is finished when an inverting cutting mode is input during the cutting in one direction cutting mode.

Title: Driver for rolling guide oscillation and acoustic measurement
Inventor: OTA HIROYUKI
IPC: G01H1/00
Filed: 1994-09-29
Abstract: PURPOSE: To prevent the generation of variation of measurement values with time by converting the rotational power of a motor into linear driving power through a slide screw and transmitting the linear driving power to a bearing block through a resilient pad having low rigidity thereby eliminating the effect of the mass and the rigidity of a driver to the natural frequency of a rolling guide. CONSTITUTION: Rotational motion of a motor 1 is transmitted through a coupling 2 to the threaded shaft 3a of a slide screw 3 and converted into linear motion of a nut 3b screwed to the shaft 3a. The linear motion is then transmitted through a bracket 5, an arm and a pusher 8 secured to the nut 3b and a low rigidity resilient pad 9 bonded to the pusher 8 to the bearing block 10a of a rolling guide 10 to be measured thus driving the block 10a in the axial direction at a constant speed. Since the block 10a comes into contact with only the low rigidity pad 9, the mass and rigidity of a driver give no effect to the natural frequency of the rolling guide 10. Furthermore, since the driving speed of the block 10a is kept constant, instantaneous drift in the measurements of oscillation and sound caused by the driver are substantially eliminated.

Abstract: PROBLEM TO BE SOLVED: To obtain ballast in a ballasted track, hard to be finely crushed by constituting the raw material of an alumina-based ceramic, a mulite-based ceramic, etc., and screening it to get a specified size distribution and mixing them. SOLUTION: The raw material of this ballast track bed 41 is constituted of ballast 43 composed of an alumina-based ceramic, a mulite-based ceramic, a silicon nitride-based ceramic.
