Title: Gravity shaft falling down prevention device at time of power failure
Inventor: KONO SHINICHI
IPC: B25J19/06
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To prevent a gravity shaft from falling down due to power failure, and thereby prevent tools, works and the like from being damaged. SOLUTION: When power failure is detected by a power failure detection circuit provided in a power supply circuit 10, a detection signal S1 is outputted to a CNC 7, and respective motor control circuits 14 through 16. The respective motor control circuits 14 through 16 executes deceleration control with a speed command (or moving command) forcibly set at zero. As a result, a spindle motor and servo motoers MZ and MX are decelerated by great torque. Besides, when a power failure detection signal S1 is inputted in the CNC 7, the CNC allows a switch 9 to be turned off, and also allows the brake to be applied to a gravity shaft by a braking device Br. Since the servo motor MZ of the gravity shaft is being decelerated so as to be controlled by great torque until braking becomes effective after power has been failed, the gravity shaft is thereby prevented from falling down to the utmost.

Filed: 1989-04-06
Abstract: PURPOSE:To decrease air resistance received by a rotary polygon mirror and to effectively suppress the occurrence of noise by making an angle formed by a flat surface and a mirror at the back side of a rotational direction greater than an angle formed by a flat surface and a mirror at the forwarding side of the rotational direction. CONSTITUTION:The flat surface 5 is formed on the boundary part between adjoining mirrors 4 of the rotary polygon mirror. The angle beta formed by the flat surface 5 and the mirror 4 at the forwarding side of the rotational direction is set greater than the angle formed by the flat surface and the mirror at the back side of the rotational direction. When the rotary polygon mirror is rotated, the air separated from the edge part 6 of the mirror 4 at the forwarding side of the rotational direction flows along the mirror 4 almost in parallel to the mirror 4 at the back side of the rotational direction by the flat surface 5. The air flows circularly and vortex 9 is produced in a space part. However, air resistance which the rotary polygon mirror receives can be decreased so that the occurrence of noise is effectively suppressed. Consequently, the disturbance of an electrostatic latent image formed on a photosensitive body can be prevented.

Filed: 1986-04-15
Abstract: PURPOSE:To reduce a fall of recording and reproducing characteristics, caused by a focal shift, and to satisfactorily record and reproduce the information by setting a level of an offset signal to a part where the amplitude of a reproducing signal by recording becomes maximum. CONSTITUTION:A level setting control circuit 30 varies stepwise a level of an offset signal 103 at a prescribed time interval by varying stepwise a level setting signal 104, inputs a recording control signal 120 to a recording circuit 20, and recording in which a focal position has been shifted at a prescribed time interval is executed. The level setting control circuit 30 samples a value of a level signal 115 by the same timing as hat which has varied the offset signal at the time of recording, catches a timing by which the value of the level signal 115 becomes maximum, selects a value of the level setting signal 104 at the time of this recording, and supplies it as an optimum set value to a focus offset generating circuit 11 at all times. In this way, even if a shift is generated in a focus error signal 101, a focal position of light beam 3 is set to an optimum state against recording and reproduction.

Abstract: PURPOSE: To improve the accuracy by means of a memory which stores in advance the data indicating the region of deceleration and a position detecting means, by interpolating the detected result about an Y axis and by comparing said interpolated data with results detected about X and Z axes.  
     CONSTITUTION: When unidirectional copying is started along an X axis from a point E in a situation wherein areas enclosed by single-dot chain lines are assigned to the regions of deceleration AWD, a control device reads the counted values given a reversible counter, compares Y coordinates Y 1 , Y 2  and Y 3  that have been stored in the region corresponding to the region of deceleration A, and evaluates and stores a Y axis coordinate larger than the counted value and nearest to the value and a Y axis coordinate smaller than the counted value and nearest to the value. Then the X and Z axes coordinates of points F 1  and F 2  are evaluated to decide the regions of deceleration by reading the X and Z coordinates of stored points A 1 , A 1 ', A 2 , A 2 ' and by interpolating them taking said Y axis as a standard.
