    Abstract: A polyfluoroalkyl alcohol, or a (meth)acrylic acid derivative thereof, represented by the following general formula: CnF2n+1(CH2CF2)a(CF2CF2)b(CH2CH2)cOR (R:H or (meth)acrylic acid group; n: 1-6; a: 1-4; b: 1-3; and c: 1-3). Polyfluoroalkyl alcohol (R: hydrogen atom) can be produced by reaction of fluoroalkyl iodide represented by the following general formula: CnF2n+1(CH2CF2)a(CF2CF2)b(CH2CH2)cI with N-methyl formamide, followed by hydrolysis in the presence of an acid catalyst, whereas polyfluoroalkyl alcohol (meth)acrylic acid derivative (R: (meth)acrylic acid group) can be produced by reaction of the polyfluoroalkyl alcohol with (meth)acrylic acid.

    Abstract: A decoder includes a first bank and a second bank. The first bank is supplied with dynamic control from a microcomputer via a data bus, and the second bank is supplied with static control data from the data bus via the data bus. The dynamic control data or the static control data is read from an address in the bank designated by an address signal. The dynamic control data read from the first bank and second bank is transferred to one of a plurality of registers designated by the address signal.

    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: A chain tension device for tensioning a cutting chain of a chain saw utilizing a guide bar having an outer periphery and a drive sprocket. The chain saw body supports the guide bar, the sprocket and a drive source. A cutting chain is wound around the sprocket and the outer periphery of the guide bar and a leaf spring is supported by the chain saw body and interposed between the guide bar and the sprocket. The leaf spring abuts and biases the guide bar away from the sprocket so as to apply automatically an appropriate amount of tension to the cutting chain.

    Abstract: There is disclosed a novel method of recovering valuable metals from an industrial by-product containing copper and arsenic and at least one metal selected from among lead, zinc, iron, silver and cadmium, said method comprising leaching the by-product with sulfuric acid in an SO.sub.2 gas atmosphere at a temperature of 70.degree. C. or higher in the presence of a solid sulfide to thereby precipitate copper selectively as copper sulfide while dissolving other metal or metals in the leach solution and then separating the copper containing precipitate from the leach solution, said leach solution containing substantially no copper.
