    Abstract: An injection-molded body according to the present invention includes a tubular body portion, an airtight seal surface formed on a peripheral surface of the body portion near one end of the body portion, and a plurality of undercuts disposed at positions around the peripheral surface of the body portion that are closer to the end than the airtight seal surface is. The undercuts prevent a seal member mounted on the airtight seal surface from falling off, in which a clearance is formed between a peripheral wall and the undercuts. The peripheral wall defines an inner hole of the body portion, and the clearance accommodates deformation of the undercuts in radial directions.

    Abstract: A tool unit for a cutting device includes a rotary blade, a blade case for covering at least a part of the blade case, and a drive device mounted to the blade case for rotatably driving the rotary blade. A handle is attached to the drive device. The blade case has a front support portion. The handle has a rear support portion. When the tool unit is used for a portable cutting device, the front support portion can be vertically pivotally supported by a front portion of the base, and the rear support portion can be supported by a guide member such that a position of the rear support portion can be changed relative to the guide member for enabling adjustment of a cutting depth of the rotary blade into the workpiece. When the tool unit is used for a table cutting device, the front support portion can be vertically pivotally supported by the table.

    Abstract: A battery-operated driver-drill (1) includes an epicycle reduction gear unit (8) which encases a switchover sleeve (26) having inner teeth (27) and outer teeth (28). The gear unit (8) is rotatably mounted on second and third internal gears (19, 20) and integrally slidably connected with a slide pate (37). By operating the slide plate (37), the switchover sleeve (26) may be slid between a first position, in which the slide plate (37) engages one of the second and third internal gears (19, 20) while engaging axial ridges (29) of a first gear case (5), and a second position, in which the slide plate (37) simultaneously engages both the second internal gear (19) and a first carrier (10) adjacent to the second internal gear (19) while disengaged from the axial ridges (2).

    Abstract: There is disclosed an improved method of treating a spent electrolyte of copper from a cell for electrolytic refining of copper for the purpose of purification and reuse of the spent electrolyte. The process comprises the steps of: pretreating the spent electrolyte for removing copper therefrom until the copper content is greatly reduced but still remains at a level which is substantially higher than the total content of various metal ion impurities, preferably to a concentration of 10-13 g/l of Cu; blowing a hydrogen sulfide gas into the pretreated solution at a temperature of 40.degree. C. or higher until the redox potential of solution becomes a certain predetermined value to precipitate metal ions; filtering the treated solution to separate the residue available as a raw material for copper smelting from a filtrate which consists essentially of sulfuric acid; and returning the filtrate to the cell for electrolytic refining of copper.
