Filed: 1989-06-22
Abstract: PURPOSE:To safely improve the yield with facilitated separation by using a specific catalyst in reacting m-xylene with isobutylene and obtaining the subject compound useful as a synthetic musk raw material or synthetic intermediate for 2,6-dimethylaniline, etc. CONSTITUTION:m-Xylene is reacted with isobutylene in an amount of 0.1-1.0mol, preferably 0.1-0.5mol based on 1mol m-xylene at 80-150 deg.C temperature under a low pressure of ordinary pressure to several kg/cm<2> (especially at about 130 deg.C under ordinary pressure) using activated clay as a reaction catalyst to afford the objective compound. Although ordinary commercially available activated clay is used as the activated clay of the catalyst, a lower moisture content is preferred and especially <=1wt.% moisture content is the optimum. The catalyst is used in an amount of 1-20wt.%, especially about 10wt.% based on the m-xylene. The reaction is carried out by a method for initially charging the m-xylene and catalyst and then continuously feeding isobutylene gas thereto.

Title: Method of removing dust from braun tube
Inventor: TSURUMI OMIO
IPC: H01J9/38
Filed: 1981-10-07
Abstract: PURPOSE:To expel and remove dust existing in spaces formed among obstacles contained in a Braun tube by applying ultrasonic vibrations to the outer wall of the Braun tube while varying the slant angle of the Braun tube. CONSTITUTION:A bulb 10 of a Braun tube is fixed to a device 11, the slant angle of which can be changed continuously, by means of a vacuum chuck 12. At the same time, an ultrasonic vibrator 13 is made to be in contact with the side wall of the panel of the bulb 10 by a given pressure. After than, the angle of the bulb 10 is continuously changed while applying ultrasonic vibrations to the bulb 10 so as to remove dust contained in the Braun tube. By the means mentioned above, dust existing in spaces formed among a shadow mask, an electron shield and so forth can be expelled, and can finally be exhausted and removed from the opening 15 of a bulb neck 14. As a result, the quality of the Braun tube can be enhanced by increasing the voltage-resistant performance of the electrodes of an electron gun, and preventing any short from developing between the above electrodes.

Title: Working machine in spinning machines
Inventor: FUJII MASAHIRO
IPC: B62B3/02
Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To permit the steady and exact vertical motion of a working machine for spinning machines without influence of fiber layers of fly waste or the like by allowing the supporter that rotatably supports a wheel via a vertically reciprocating member to move vertically by the rotation of a rotary cam. SOLUTION: The main body of the working machine 4 in spinning machines is guided via the supporting roller set on the part of the working machine on the spinning machine side to the supporting rail on the front face of the frame 1 and allowed to move in the longitudinal direction of the frame 1. When the main body of the working machine 4 begins inclining toward the floor, the driving motor actuates by the action of the inclination detector. Thus, the rotary cam rotates to reciprocate, via the vertically reciprocating member 19, the supporter 8 that rotatably supports wheel 7 whereby the main body of the working machine 4 is held horizontally to the floor face.  Even when waste fluffs or the like stick to the rotary cam 22, the rolling members 20, 21 during its running operation, the friction resistance between the vertically reciprocating member 19 and the upper face of the vertically swinging frame 14 is kept small, because the vertically swinging frame moves circularly as the rolling member 21 rolls on the upper face of the vertically swinging frame 14, thus permitting smooth swinging motion of the vertically swinging frame.

Title: Method and device for adjusting position of main pole of magnetic roller
Inventor: MATSUI NAOHISA
IPC: G03G15/09
Filed: 1990-06-19
Abstract: PURPOSE:To adjust the position of the main pole of a magnet with high accuracy by detecting information on magnetic force all over the periphery of a magnetic roller by a magnetism sensing element opposed to the magnetic roller and specifying the position of the main pole of the magnetic roller according to rotation angle based on the detected result. CONSTITUTION:A stepping motor intermittently rotates a rotary shaft and the output of a Hall sensor 40 is read in every time the magnetic roller 81 is rotated.

The control part 30 successively accumulates the data together with the rotation angle of the roller 81. When the roller 81 is rotated over 360 deg. and the density of the magnetic flux is measured all over the periphery of the roller 81, the control part 30 specifies the rotation angle at which the density of the magnetic flux shows a peak value based on the relation of the density of the magnetic flux G to the rotation angle theta of the magnetic roller. Thus, the position of the main pole of the magnetic roller is accurately adjusted.
