Title: Casing top joint of air hammer boring device
Inventor: KAWABE YOSHIO
IPC: E21B4/14
Filed: 1998-11-18
Abstract: PROBLEM TO BE SOLVED: To improve working efficiency by absorbing impact force transmitted from an air hammer by a rubber-like elastic body through the rubber-like elastic body on a casing top joint part. SOLUTION: An inner cylinder 3 and an outer cylinder 6 are fixed so that a gap 4 is possessed between the inner cylinder and the outer cylinder 6 on a frame body such as a mold, and molten unvalcanized rubber is pressed in the gap 4 from the trough hole 8 of the outer cylinder 6. The unvalcanized rubber filled into the gap 4 by heating is valcanized to be a rubber-like elastic body 7. Then, the joining part of the tapered part 9 of the outer cylinder 6 and the tapered part 11 of a hard plastic pipe 10 such as hard vinyl and hard polyethylene is joined by an adhesive. As the result, upper and lower impact force from an air hammer is absorbed by the rubber-like elastic body of a easing top joint, and transmission from the top joint to an upper easing is prevented. Thereby a welding facility is not needed, and joining is performed simply in a short time to improve working efficiency.

Title: Thermal transfer recording sheet
Inventor: SHINOHARA HIDEO
IPC: B41M5/50
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To prevent the dislocation of an image receiving layer part during the image forming period of time, and also prevent the gloss of a transferred image receiving part from becoming extraordinarily high by forming an intermediate layer containing at least a binder resin and a filler between a base material and an image receiving layer. SOLUTION: The base material can include a laminated base material of foam film or synthetic paper and cellulose paper. The intermediate layer is formed of binder resin and a filler to form an excellent adhesiveness between the base and the image receiving layer. Since the binder resin is needed to give an appropriate adhesiveness in an interface between the image receiving layer and the intermediate layer, it is preferable to be polyurethane resin. The filler is preferable to be particles of silicone resin as inorganic particles. For the image receiving layer, conventional one can be employed s a dye transfer method. By the use of the intermediate layer, an adhesiveness is controlled between the base material and the image receiving layer for preventing the shift of the image receiving layer part, or regulating the degree of luster.
