Title: Ceramic glow plug
Inventor: ITOU TSUNEO
IPC: F23Q7/00
Filed: 1983-08-26
Abstract: PURPOSE:To reduce a manufacturing cost of a ceramic glow plug by a method wherein a specified glass material is coated on the plug, baked at a specified temperature, while a ceramic heater, a metallic cap composed of stainless steel and a metallic outer cylinder are braze-bonded with copper through a glass layer. CONSTITUTION:A glass layer 13 having a ceramic and a glass material having a glass constituent with good wetting property coated and baked thereon in advance is formed at a brazed part of a ceramic heater 1 between a metallic outer cylinder 4 and a metallic cap 9, thereafter they are brazed with copper in non- oxidation atmosphere. It is preferable for a glass material to have a viscosity of 10<4>P at a value of 2.0X10<-6>/ deg.C approximating to that of a ceramic sintered material and a sintering temperature of 1,150-1,350 deg.C. In this way, it is made possible to make a substantial reduction of cost by utilizing a stainless steel material having anti-oxidation characteristic as well as a heat-resistant characteristic in the metallic outer cylinder and the metallic cap and by holding a binding force with utilization of copper brazing material at low cost.

Filed: 1990-06-14
Abstract: PURPOSE:To efficiently collect developer without leaking it out from the aperture part of a collection port by providing a guide member which distributes and makes the developer drop inside the collection port. CONSTITUTION:The V-shaped guide member 5 having the bottom part where a hole 5a is formed is provided inside the collection port 1a. Then, the developer discharged from a cleaning device drops in the guide member 5 from the collection port 1a and slides down along the side wall 5b of the guide member 5. Besides, it is accumulated on the bottom part and dispersed from the hole 5a provided on the bottom part and the both end parts of the guide member. Then, it is made to drop to the bottom part of a developer collection tank 1. At this time, one part of the dropped developer splashes upward. However, since the passage thereof is shielded by the guide member 5, it is not leaked to the outside from the collection port 1a. Thus, the collected quantity of the developer is precisely detected and the collecting efficienty thereof is improved at the same time.
