摘要： PCT No. PCT/JP81/00014 Sec. 371 Date Sep. 10, 1981 Sec. 102(e) Date Sep. 10, 1981 PCT Filed Jan. 21, 1981 PCT Pub. No. WO81/02127 PCT Pub. Date Aug. 6, 1981.In an electric discharge machining apparatus for machining a workpiece by confronting an electrode and the workpiece through an insulating machining solution, feeding the electrode to the workpiece and causing electric discharge between the confronting electrode and workpiece the difference between the most advanced position of the electrode relative to the workpiece and the present position of the electrode is detected and a signal is outputted by identifying the interelectrode state in accordance with the detected result. Thus, the propriety of the interelectrode machining gap state in the electric discharge machining are accurately observed, and the workpiece is machined under preferable machining conditions.

摘要： A wet type magnetic separator has a generally cylindrical stationary magnet device with its axis fixed and extending substantially horizontally with a cut away recess open from the top of the cylindrical body and to one side along its periphery. Sets of plural permanent magnets and yokes having a similar configuration to said magnets are coaxially aligned in side-by-side arrangement so that adjacent yokes have opposite polarities. A rotary drum is disposed coaxially and rotatably to the stationary magnet device and adjacent about the stationary magnet device, and is covered with substances of high magnetic permeability functioning as a group of induced poles. Thus, the magnetic separator can separate magnetic particles by means of magnetic force from non-magnetic particles of the raw materials, which are supplied to the top of the rotary drum.

摘要： An ornamental flower bed base assembly or matrix material comprising a flower bed base plate having a plurality of insertion through-holes disposed at appropriate intervals and a plurality of flower plant holders each having a side wall provided with irrigation orifices and an open top end, each of the flower plant holders being removably engageable with the respective insertion through-holes of the base plate. This matrix is lightweight and can be easily transported to the contemplated site of erection. Using this ornamental flower bed matrix material, a variety of ornamental flower beds can be constructed easily at site. The resulting flower beds are attractive and easy in maintenance.

摘要： Herein disclosed is an electric discharge machine, by which, after the machining operation of a workpiece by an electrode has reached a predetermined position, the machining operation is further accomplished while rocking the electrode in a plane generally normal to the feeding direction of the workpiece for the machining operation. The workpiece has its respective portion uniformly machined by effecting the machining operation accompanied by the rocking motions for a preset period, e.g., either for a predetermined time period or a predetermined number of the rocking motions so that the precision of the finishing operation can be improved.
