Title: Thermal head and thermal transfer recording device
Inventor: SUGAIWA TAKAYUKI
IPC: B41J2/335
Filed: 1989-07-19
Abstract: PURPOSE:To obtain a thermal head having an anti-sticking layer by coating the surface of a heat generating section with a specific layer containing a polymer. CONSTITUTION:A thermal head A consists of a heat generation part C provided on one end of a protrusion and an electric contact which electrically connects and electrode conductor 4 of the heat generating part to a thermal transfer recording device on the other longitudinal side corresponding to the protrusion. At least, one kind of polymer selected from among a group of fluorine- containing polymer and a siloxane-containing polymer is used as an anti-sticking layer 7 on the surface of the heat generating part C at the thermal head A. Consequently, a sticking phenomenon does not generate, if a thermal transfer recording medium without an anti-sticking layer 7 is used. If the phenomenon happens to occur, the thermal head A can be replaced quickly.

Title: Cab-over vehicle steering system
Inventor: TODA TATSUYOSHI
IPC: B62D1/19
Filed: 1996-07-17
Abstract: PROBLEM TO BE SOLVED: To protect a driver from impact resulting from the backward movement of a steering column with a simple structure. SOLUTION: An upper steering shaft 6 is bendable with respect to a lower steering shaft by means of a joint 10, and an upper tube 5 of an upper column 2 in a steering column 1 is joined to a reinforcement 16. When an impact is applied to a front panel 11 due to a collision or the like, the upper column 2 is bent forward or toward the front panel 11 over the reinforcement 16 by means of a joint part 4 by the pressure of a lower column 3 at its upper end by a pipe stay 22. The bending of the upper column 2 toward the front panel 11 thus requires no effects of a shift rod or the like, which permits the structure itself to be applied even to cab-over vehicles employing either of shift modes including a column-shift mode and a floor-shift mode.

IPC: B28B21/58
Filed: 1988-07-29
Abstract: PURPOSE:To form efficiently a mortar lining layer with uniform thickness and excellent quality to a small caliber steel pipe by performing mortar lining while the mortar is sprayed continuously to a steel pipe inner surface and molded centrifugally through the rotation of the steel pipe. CONSTITUTION:The mortar transferred through a pressure feed pipe 5 at a high speed levitated state is dispersed at the top end 601 of corn-shaped control protrusion 60 of a nozzle chip 6 opposed to the axial direction of the pressure feed pipe, and diverted the flow direction from the corn surface to the radial subsequently, and then it spouts from the entire periphery in a spray state, adhered impactly to the steel pipe inner surface 100. Owing to the fact that the steel pipe 1 is being rotated, the mortar is press-adhered to the steel pipe inner surface through centrifugal force. And, since the process may be continued following the movement of the spray carriage 3, the lining layer 8 with uniform thickness is created in the axial direction. By continuing the rotation of the steel pipe 1 even though the spraying work has been finished, the lining layer 8 is further compacted by centrifugal force. The number of rotation of the steel pipe 1 is controlled to be 200-450rpm, for instance, in a spray process, and 340-550rpm after sprayed.
