Abstract: A clamp 100A for connecting formwork panels 50, 50 together at a right angle has a symmetrical shape and comprises a generally triangular central section 1, one intermediate lever 3 connected pivotally to each of opposed sides of the central section 1, and an L-shaped holding arm 2 connected to the intermediate lever 3 by means of a link 4 that is pivotally joined with both the intermediate lever 3 and the holding arm 2. The central section 1 has two equal sides a, a which extend perpendicular to each other and at which the central section 1 engages with joint members 52, 52 of formwork panels 50, 50. Notches 1c are formed on each side a, and are adapted to bite into one joint member 52. Each side a of the central section 1 is thus capable of engaging very closely with the joint member 52. The holding arm 2 is also provided with notches 2c, so that the holding arm 2 also can engage very closely with the joint member 52.

Abstract: A method of producing a casting by using a plastic core. The plastic core is made of a thermoplastic resin and set in a casting mold so as to form a cavity in the casting mold. A molten metal such as aluminum is poured under pressure into the cavity to form the casting (product). The plastic core maintains its initial shape during casting. The remaining heat of the casting or the solidifying metal causes the plastic core to melt after the casting so that the molten plastic core is easily removed.

Abstract: A machine for winding film, a method of manufacturing spools of pre-stretched film, and spools of pre-stretched film obtained as a result, are disclosed. The method of winding spools of pre-stretched stretchable film includes importing oscillation to the film with a component perpendicular to the axis of the film. For example, during pre-stretched and winding of the film on a take-up spool, a feed spool, i.e. a spool from which the stretchable film for stretching is taken, is caused to oscillate, and/or the take-up core is caused to oscillate. This ensures that successive layers of film are offset, in particular at the margins of the film. Spools of film obtained in this way do not have portions of extra thickness and lower tension at the margins as is the case prior art spools of pre-stretched film.

Abstract: A battery terminal case includes an outer case into which a battery is inserted such that an anode and a portion of a cathode can of a battery can be enclosed; a cathode terminal extension member inserted into and nested inside the outer case and contacting the portion of the cathode can; and an anode terminal extension member inserted into the inside of the cathode terminal extension member and contacting the anode of the battery. Accordingly, by using the anode and cathode terminal extension members respectively contacting the anode and the cathode of the battery, damage to the battery itself can be prevented since welding is not necessary during the manufacturing of a battery pack, and contact defects between the battery and the terminal in the conventional terminal case, occurring as the elastic force of the terminal weakens, can be prevented.

Abstract: A fuzzy rough classification section 7 classifies an input pattern into a plurality of category groups and calculates their attribution factors. A plurality of fine classification sections 8 calculate similarities in respective category groups.

A force learning control section 17 performs a supplemental learning operation, if the input pattern is rejected regardless of its correctness, until its reject judge value is reduced below a predetermined reject threshold.
