Title: Ceramic glow plug
Inventor: YOKOI SHINICHI
IPC: F23Q7/00
Filed: 1982-11-08
Abstract: PURPOSE:To uniformize temperature distribution when the surface of a heating body is heated by a method wherein a relative dimension between a heating wire and a ceramic insulating body is specified and the configuration of the heating wire, burried into the ceramic insulating body, is designed so as to be an elliptical coil having a specified dimension. CONSTITUTION:The heating wire 9, consisting of the wire of resistance heating metal such as tangsten or molybdenum, is coiled so as to have a given elliptical configuration and is bent into U-shape at the tip end part thereof while the heating wire 9 is burried into the ceramic insulating body 10, made of principally silicon nitride, for example, and having a circular section, thus, the heating body 8 is constituted. The relative dimension between the heating wire 9 and the ceramic insulating body 10 is designed so that theratio of the diameter (a) of the circumcircle of two rows of the elliptical coils 9-1, 9-2 at the parallel part of the heating wire 9 bent into the U-shape and the outer diameter (b) of the ceramic insulating body 10 becomes 35:100-70:100. In case the ratio is up to 35, a heating characteristic is inferior and the crack of ceramic is easy to be caused since a temperature difference between the heating wire and the surface of the ceramic insulating body is large. On the other hand, in case the ratio is over 70, the heating property may be improved but the heating body 8 becomes vulnerable to breakage since the temperature difference between the temperatures of the heating wire and the surface of the ceramic insulating body becomes large.

Filed: 1986-08-22
Abstract: PURPOSE:To prevent the passivation film of a pellet from cracking or the electrodes of the pellet from being disconnected or shortcircuited by disposing a guard for surrounding the pellet near the side of the pellet. CONSTITUTION:A pellet 4 is bonded to a bottom of a recess 7 of a tab 3 to be surrounded near the periphery by a sidewall 8 and a guard 10 made of a flange 9. Thus, it can prevent the passivation film (not shown) of the pellet 4 from cracking or electrodes formed at the outer peripheral edge of the pellet from being disconnected or shortcircuited. That is, since there is thermal expansion coefficient difference between the pellet and a package, a shearing force is acted, but the maximum value deltamax is acted on the outer peripheral edge of the flange 9, and less stress deltas than that is acted on the outer peripheral edge of the pellet 4. Thus, a crack due to the shearing force is not generated.

Filed: 1996-07-04
Abstract: PROBLEM TO BE SOLVED: To reduce the equipment cost over the entire part of the device by oscillating works via auxiliary implements freely oscillatable around the top ends along the works. SOLUTION: The works W are lowered from a hoist into a treating liquid L while a frame 13 is held hung until the works are fully immersed into the liquid. An air cylinder 12 is energized to oscillate the auxiliary implements 6 around a horizontal shaft 6a. The works W connected by means of wire ropes 8 are oscillated around the hangers 3 while the works are hung to hanging members 1 according to the oscillation. Then, even if air pockets exist in the works W, these pockets are eliminated. Since the works W are hung down, the device is applicable regardless of differences in the sizes and shapes and, particularly, there is no need for jigs for matching the device with the works W. Al wires, etc., which are not eroded by the treating liquid L, are used for the hanging members. The saving of the materials is resulted if these wires and the conductive members 1a are used in combination.
