Filed: 1987-07-06
Abstract: PURPOSE:To improve the output level of a microwave without deteriorating the frequency stability against load fluctuation by folding an output side strip line toward the oscillator side strip line on the way of the output side strip line over the connecting terminal connecting to a resistance attenuator. CONSTITUTION:The output side strip line 6' on its way over the connection terminal connecting to a resistance attenuator 7 is folded toward the oscillator side strip line 2 so as to surround a dielectric resonator 1 partly from the outer side. The open end of the output side strip line 6' coupled with the dielectric resonator 1 magnetically has an interval (d) with the oscillator side strip line 2 similarly to the case with a conventional oscillator. In adopting the shape for the output side strip line 6' in this way, the inductance component and the static capacitance component are increased at the folded part 6'a. Then both the components act on the dielectric resonator 1 to improve the coupling between the output side strip line 6' and the dielectric resonator 1. Thus, the output level of the microwave is improved thereby improving the stability of the frequency against load fluctuation.

Title: Prevention of defective painting when conveyor stops in electrodeposition painting
Inventor: NAKAYAMA MAKOTO
IPC: C25D13/22
Filed: 1983-09-15
Abstract: PURPOSE:To prevent the surface of a material to be coated from being unevenly painted by generating the same flow as the liquid flow which arises on moving of the material to be coated in an electrodeposition liquid when the material stops in the electrodeposition liquid owing to stoppage of a conveyor. CONSTITUTION:A material 4 to be coated is continuously dipped by a hanger 6 detained to a conveyor 5 into a cationic electrodeposition liquid 2 contained in an electrodeposition cell 1 by which the material 4 is electrodeposition-painted. The liquid 2 is sucked through a suction port 8 by a pump 9 and is discharged from injection nozzles 7 to the extent of avoiding clogging of the nozzles 7. When the material 4 stops in the liquid 2 owing to stoppage of the conveyor 5, a motor is controlled by a sensor 11 which senses the stop to increase the liquid flow by the pump. The similar liquid flow to the liquid flow generated when the material 4 moves is thereby generated in the liquid 2. Settling of the components having the larger specific gravity in the liquid 2 is thus prevented and the surface of the material 4 is uniformly painted without unevenness.
