Title: Screen printing device of cream solder
Inventor: SAKAMI SEIJI
IPC: B41F15/42
Filed: 1993-05-11
Abstract: PURPOSE:To obtain a screen printing device of cream solder which enables a printing plate to be separated more efficiently by installing a pressing member for pressing a mask against a substrate when vibration is applied to a vibration means provided on a support table side so as to allow the means to come in contact with the mask. CONSTITUTION:A squeegee 6 becomes separated from a substrate 13 or a transport conveyor 14 when cream solder 21 is applied. In this case, a cylinder 7 presses the squeegee 6 so that its lower end part is positioned far below the upper surface of the substrate 13. Under this state, a piezoelectric element 15 is driven to transmit oscillation to a mask 9 directly. Further, in this case, the squeegee 6 presses the mask 9 to the substrate 13. Consequently, the mask 9 is bound to generate oscillation which results in a deterioration of the structural viscosity, in a part near a pattern hole 9a, of cream solder 21. Thus the cream solder 21 is easily separable from the pattern hole 9a, that is, is apt to stick to a substrate 13 side more easily, which contributes to the separation of a printing plate significantly.

Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To reduce crossover distortion and to prevent a through current from being generated when an input voltage is switched, by providing an input stage being constituted by a differential amplifier and a voltage inversion means consisting of p- and n-type MOS transistors that operate according to an output signal. SOLUTION: An operation amplifier 10 is connected to a first current-mirror circuit 6 and a second current circuit 7. The output points of both circuits 6 and 7 are connected to the gate electrodes of a pMOS transistor QP 3 and nMOS transistor QN 3 constituting an output stage 19. When the potential of an inversion input terminal 4 of the operation amplifier 10 is fixed and the potential of a non-inverted input terminal 3 is increased, the circuit 6 outputs a low level, the QP 3 is turned on, the circuit 7 allows the QN 3 to be turned off at the low level, and the output of an output terminal 5 is set to a high level. Also, when the potential of the terminal 3 is reduced, the output is set to a low level by an opposite operation. Therefore, crossover distortion can be reduced and a through current can be prevented.

Filed: 1985-05-22
Abstract: PURPOSE:To perform speed change efficiently by limiting relative rotation of movable half pulley against fixed half pulley thereby eliminating slippage of V-belt. CONSTITUTION:Upon application of load heavier than predetermined level onto a driven shaft 35, relative rotation is produced between the pulley guide collar 39 and fixed and movable pulley shafts 40, 43. Consequently, the fixed half pulley 42 and the movable half pulley 45 will never rotate relatively thus to move the movable half pulley 45 axially. As a result, V-belt 28 of V-pulley 36 will never slip resulting in smooth and highly efficient speed change.
