A polishing agent recovery and reuse method and device for the same removes large impurities by a filtration device, concentrates by an ultrafiltration device, and continuously recovers polishing agent. Polishing agent used in polishing a semiconductor board or a coating formed on top of a semiconductor board is collected in a pre-processing container after use. Large impurities are removed by a dual fine filtration device. The resulting filtrate is concentrated by an ultrafiltration device. The concentrated solution may then be mixed with filtrate from the dual fine filtration device to further concentrate the polishing agent. The concentration of the polishing agent in the concentrated solution, the pH, and the temperature of the solution are continuously monitored and controlled. The filtrate of the ultrafiltration device is further treated to remove impurities, resulting in pure or ultrapure water. The recovered polishing agent may be reused in further polishing steps.

A tape cable provided with connector portions in its end portions is wound spirally, and a reinforcing tape having elasticity is stuck to the outer circumferential surface of the tape cable in the vicinity of the connector portion. In an inner cylinder, in the vicinity of the end portion on the connector side of the reinforcing tape provided on the tape cable, a support portion is provided in a position to support the tape cable together with the reinforcing tape. When the connector portion is installed in the inner cylinder, the tape cable is inserted and held between the support portion and the inner cylinder together with the reinforcing tape. Accordingly an end portion of the reinforcing tape is fixed, so that buckling between the connector portion and the support can be prevented. Buckling beyond the portion can be prevented by the rigidity of the reinforcing tape.

It is an object of present invention to provide an efficient method for grinding of the surface of a work and an apparatus thereof, using a magnetic fluid containing abrasive grains.The method of the present invention for grinding a work immersed in a magnetic fluid containing abrasive grains filled in a container, said magnetic fluid being given a magnetic field from the outside of the container with magnet comprises: immersing a floating pad in said magnetic fluid at a position adjacent to the work, said floating pad being given a buoyant force by said magnetic field whereby the abrasive grains existing between the floating pad and the work are pushed onto the work and giving a mutual motion between the work and the magnetic fluid containing abrasive grains.In conventional method for grindings using a magnetic fluid containing abrasive grains and without the floating pad, the grinding load has been mainly dependent upon the buoyant force of abrasive grains, but the grinding rate thereby was too small owing to rather little buoyant force of abrasive grains.According to the present invention using the floating pad, the grinding rate is significantly improved by strongly pushing abrasive grains onto the surface of the work, resulting from larger grinding load and the resistant power of the floating pad to the grinding direction.

Provided is a medium delivery control apparatus that can prevent the wear of a means relating to the delivery of a recording medium and extend the life of the delivery means. The medium delivery control device controls a medium delivery means for connecting, disconnecting and delivering the recording medium with respect to a deep cell, and includes a first detection recording means for detecting and recording the storage or non-storage of the recording media and the identity of the recording media being stored for each deep cell, a second detection recording means for detecting and recording the number of insertions and removals of the recording medium for each deep cell, a storage point candidate searching means for searching for a storage point candidate cell on the basis of the recording of the first detection recording means, a number-retrieval determining means for retrieving the number of insertions and removals of the recording media at the retrieved storage point candidate cell and determining whether the number exceeds a threshold on the basis of the recording of the second detection recording means, and a medium-delivery control means for controlling the medium delivery means such that the recording medium is delivered to the retrieved storage point candidate cell if the threshold is not exceeded.

摘要:
Silica and boron are particularly removed at high rate in processing by the electrodeionization apparatus. An electrodeionization apparatus has an anolyte compartment 17 having an anode 11, a catholyte compartment 18 having a cathode 12, concentrating compartments 15, and desalting compartments 16. The concentrating compartments 15 and the desalting compartments 16 are alternately formed between the anolyte compartment 17 and the catholyte compartment 18 by alternately arranging a plurality of anion-exchange membranes 13 and a plurality of cation-exchange membranes 14. The desalting compartments 16 and the concentrating compartments 15 are filled with ion-exchanger. The anion exchanger/cation exchanger volume ratio is 8/2 to 5/5. Electrode water flows into the anolyte compartment 17 and the catholyte compartment 18. Concentrated water is introduced into the concentrating compartments 15. Raw water is fed into the desalting compartment 16 to produce the deionized water from the desalting compartment 16. Water containing silica or boron at a lower concentration than the raw water is introduced into the concentrating compartments 15 as the concentrated water in a direction from a side near an outlet for the deionized water toward a side near an inlet for the raw water of the desalting compartments 16. At least a part of concentrated water flowing out of the concentrating compartments 15 is discharged out of a circulatory system.

To facilitating arrangement of a muffler and a rear fender without increasing the size of a motorcycle. A motorcycle includes a front wheel, an engine, and a rear wheel disposed on a vehicle body in this order from the front. An exhaust pipe extends rearwardly from the engine with a muffler provided at the rear end of the exhaust pipe. The muffler is disposed on the rear portion of the vehicle body frame between left and right rear frames above the rear wheel. Stays extend downwardly from the left and the right rear frames. A rear fender is disposed below the muffler and is attached to the stays. The muffler is tapered from the upper portion toward the lower portion when viewed from the rear. The left and the right rear frames comprise a rear seat, which is wider than the muffler, at a level higher than the muffler.

A steering damper device for a two-wheeled vehicle presents a problem with regard to facilitating the viewability of a meter and to increase the degree of freedom of the meter in layout to bring down the center of gravity of the vehicle. A two-wheeled vehicle includes, at a front end of a main frame, a head pipe for rotatively supporting a steering shaft. At the front part of the head pipe, there is installed a meter stay for supporting a meter. Between the head pipe side and the steering shaft side there is interposed a steering damper device for restricting abrupt run-out of the handlebar. The steering damper device is arranged forward of the head pipe and below the meter stay to make effective use of the space of the vehicle and further to increase the degree of freedom of the meter in design.
