Title: Solder printer and solder printing method
Inventor: NODA AKIHIRO
IPC: B41F15/40
Filed: 2001-10-15
Abstract: PROBLEM TO BE SOLVED: To provide a solder printer and a solder printing method which perform the simple and secure printing of a soldering paste, even when a stencil with small-diameter holes corresponding to a small-size wiring pattern is used. SOLUTION: The action of a pressurizing part 20, which exerts pressure to a soldering paste 80 applied to the stencil 10 and the action of a stencil drive part 30 which drives the stencil 10, are controlled by a control part 40. Thus it is possible to subtly adjust a pressurizing force and consequently, the lifting of the stencil 10 and the timing of applying a pressurizing force can be performed by making their optimal combination. For this reason, the scattering of the soldering paste 80 due to overpressurizing can be prevented from occurring and the printing of the soldering paste 80 without depending on the skill of an operator is ensured.

IPC: F02D41/32
Filed: 2001-11-05
Abstract: PROBLEM TO BE SOLVED: To provide a variable valve timing device capable of performing a stable combustion even if an ignition timing is delayed. SOLUTION: This controller is explained according to a flow chart shown in Fig. 6. In step 301, it is judged whether the requirements for execution of catalyst premature warming-up are satisfied or not.

When the intake valve is not at the target open position, in step 303, the intake valve 8 is set to the target open position where a sufficient intake air flow velocity can be obtained, and this routine is terminated. Thus, since the intake valve 8 is set to the target open position where the sufficient intake flow velocity can be obtained, fuel adhered to an intake passage can be evaporated and, since mixture in a combustion chamber can be agitated sufficiently, an air/fuel ratio is prevented from being disturbed.
