Title: Locus controlling method and locus control device
Inventor: HATTORI KAZUYA
IPC: B23Q15/22
Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To suppress generation of vibration by making a movable body perform accelerated motion and decelerated motion by using maximum acceleration/deceleration speed when command speed is prescribed speed or more, determining deceleration based on time required for acceleration or decelerating and stopping the movable body when command speed is less than prescribed speed and making the movable body perform accelerated motion and decelerated motion. SOLUTION: The comparison of calculated acceleration/deceleration time T and preliminarily set lowest acceleration/deceleration time Tmin is performed (S 52). In this case, the lowest acceleration/deceleration time Tmin is considered as a value specific to a machine. When acceleration/deceleration is constant and time required for accelerating speed up to command speed is longer than this lowest acceleration/ deceleration time Tmin, vibration is not generated. Or when vibration is within an allowable range, even if vibration is generated, and time required for accelerating speed up to command speed is shorter than this lowest acceleration/deceleration time Tmin, a value is preliminarily and experimentally determined for a value for generating vibration of an allowable value or more and is stored in a memory 72.  Thus, even if a comparatively low speed command is given, vibration of a mobile body is prevented and a locus control with high accuracy is made possible.

Title: Ion source
Inventor: NAITO KATSUO
IPC: H01J27/20
Filed: 1993-12-07
Abstract: PURPOSE:To provide an ion source which is compact and has improved polyvalent ion yield. CONSTITUTION:Plasma electron produced by arc discharge in a first discharge chamber 7 is utilized for ionization in a second discharge chamber 8. At this time, the plasma electron obtained in the first discharge chamber 7 reciprocally flies, between an intermediate electrode 6 and a ripeller electrode 16 turning by a work with a magnetic field by a magnetic pole 5.5 and an electric field by an anode 12 and then sealed in. Thereby, efficiency of the ionization is improved and the yield of the ion is improved and much more polyvalent ion can be obtained. Strong magnetic field can be generated by reducing a space of the magnetic pole 5.5 by penetrating the magnetic pole 5.5 into a vacuum chamber 1 without expanding a magnetic field generator including the magnetic field 5.5. Supplying an environment of the strong magnetic field maintains improved arc discharge and promotes the generation of the polyvalention.

Title: Water treating agent
Inventor: NASU JUN
IPC: C02F1/68
Filed: 1989-11-27
Abstract: PURPOSE:To obtain a water treating agent for producing nice drinking water capable of being stored over a long period of time by lowering the pH of seawater with a strong acid, increasing the pH with a strong alkali and firing the resulting precipitate at a high temp. after drying. CONSTITUTION:The pH of seawater is lowered to <=2 with a strong acid, e.g. prepd. by adding concd. sulfuric acid to highly basic ionized water contg. ions of weak acids such as phosphoric acid and silicic acid. The pH is then increased to >=13 with a strong alkali such as NaOH or KOH to precipitate salts whose solubility is reduced at a high pH, e.g. sulfates. The resulting precipitate is dried by heating and fired at a high temp. to obtain activated ceramic-like solid matter. When this solid matter is added to city water, the odor of bleaching powder is removed and nice drinking water is produced. Since this drinking water is kept at pH9-12, the generation of various bacteria is prevented and storage over a long period of time is enabled.

Title: Discharge lamp lighting device
Inventor: UCHIHASHI MASAAKI
IPC: H05B41/24
Filed: 1989-11-27
Abstract: PURPOSE:To prevent a discharge lamp from flickering by gradually decreasing on-duty for a certain period from polarity reversal of the lamp current so that the lamp current becomes approx. constant in relation to varying impedance within a semi-cycle of the current flow to the discharge lamp. CONSTITUTION:A correction circuit 4 is installed between a differential amplifier circuit and a comparator circuit 18 in order to superpose the output of a low frequency generator circuit 13. For a certain period after polarity reversal of the lamp current, on-duty is decreased gradually so that the lamp current becomes approx. constant in relation to varying impedance with in a semi-cycle of current flow to the discharge lamp. Thus the lamp current can be kept approximately constant in relation to varying impedance within a semi-cycle of current flow. This process suppresses any increase of ripple component to prevent the discharge lamp from flickering.
