Abstract: PURPOSE:To prevent the collision of bobbins held by a doffing arm with bobbins placed on a peg conveyor and improve the doffing efficiency, by moving the peg conveyor while times to the backward and forward movement of the doffing arm in the doffing in the direction perpendicular to that of the peg conveyor. CONSTITUTION:The front doffer 10 in front of a roving frame having top supported flyers placed in the zigzag form is provided with a peg conveyor 34 having pegs 35 of the same pitch on which empty bobbins (5A) are previously placed. In doffing, a doffing arm 32 (32A and 32B) is advanced from a doffing head of the doffer 10 to hold full bobbins 9 on bobbin rails 6 of the roving frame and retreated to place the full bobbins 9 on empty pegs 35 on the peg conveyor 34. In the process, the conveyor 34 is moved while timed to the retreating operation thereof to prevent the collision of the full bobbins 9 held by the doffing arm 32 with empty bobbins (5A) on the conveyor 34. In case the doffing arm 32 holds the empty bobbins (5A) on the conveyor 34 and advances to mount the bobbins (5A) on the bobbin rails 6, the conveyor 34 is moved while timed to the advancement of the doffing arm 32 to prevent the collision of the bobbins.

Filed: 1992-01-27
Abstract: PURPOSE:To reduce the noise of a comparator output signal by separately providing a power supply supplying a power to a pre-amplifier stage and a latching comparator stage and the power supply supplying a power to an output stage. CONSTITUTION:A separate power supply is used for an output stage 17 which is a peripheral circuit of a comparator circuit, independently of the power supply operating the comparator circuit. A constant current source circuit controlling the current flowing to the output stage 17 is designed separately from a constant current source circuit 14 controlling the current flowing to the comparator circuit. Therefore, the comparator which prevent the noise generated in the comparator circuit from appearing at a comparator output terminal 10 via the power supply or the like can be obtained, and the clock signal which is used in a latching comparator stage 16 can be prevented from being transmitted to the output stage 17 via the wiring of the constant current source circuit 14.

Filed: 1980-02-01
Abstract: PURPOSE:To effectively utilize resin and uniform the molding conditions by providing, instead of the runners, a hole for the exclusive use of casting resin material at the position extremely close to the cavity and directly connecting the resin supplying part and the cavity by a gate. CONSTITUTION:The upper mold 6 is provided with a resin material casting hole 16 and alighned with the lower mold 17. A thermosetting resin 18 is cast 16 and pressurized by a plunger 9. The resin melted by the heated mold is forced into the cavity. In said constitution, because the resin passage is extremely short, the filling into the cavity is completed within several seconds. The volume of the resin becomes one over several tens of that by the conventional transfer molding method, and the resin flows without preheating. Because there is no runner the amount of the resin used decreases, so that the utilization rate of the material improves remarkably. Moreover, because the positional relationship between the resin supplying part and the cavity is improved, the injection pressure of the resin and the filling speed into the cavity are uniformed, so that the resin can be molded under extremely uniform conditions.
