Title: Handrail unit for passage
Inventor: SUZUKI SUSUMU
IPC: E04F11/18
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To simplify works and reduce construction period by unitizing a handrail part and a support part and erecting the handrail part and attaching the support part to a building frame body at site. SOLUTION: Rigid vinyl chloride resin is molded to form a handrail part 2 and a support part 3 at the same time in a handrail unit 1 for a passage. The handrail part 2 has a long gourd-shaped body in the section and it is housed in a recess 31 of the support part 3 to unitize it. A support shaft 22 is integrally molded in the end face 21 of the handrail part 2. The handrail part 2 can be rotated around a pair of support shafts 22 and the head 23 is forcibly pulled out of the hook-shaped edge 31A of the recess 31 and pushed it down forward to bring out the function as a handrail.  In this way, as the handrail unit 1 for a passage is unitized, it is all we have to do that the handrail part 2 is erected and the support part 3 is previously fitted to a wall body 100 as a building frame body at site and futher, the handrail part 2 is fixed to the support part 3 by a fixing piece 5 of a tenon. Accordingly, the structure is not only convenient for transportation but also simple for execution and hence, it is effective for reduction of the construction period.

IPC: B26B19/04
Filed: 1993-02-18
Abstract: PURPOSE:To prevent the breakage of an outer blade by the top end of a long hair guiding comb. CONSTITUTION:A comb 46 is arranged on an outer blade holder 35 having an outer blade 3 laid in arch thereon, and the top end of the comb teeth 45 of the comb 46 is extended until it reaches a position near the top part 3a of the outer blade 35. The outer blade 3 is supported to the outer blade holder 35 in such a manner that one end 3b opposite to the comb side is fixed, and the other end 3 on the comb side is movable. Thus, since the outer blade 3 escapes downward along the inside of the comb 46 even when an external force in an arrow direction A acts on the outer blade 3, it is never broken.

Title: Circuit breaker and frp rod for circuit breaker operating rod
Inventor: TAKEUCHI RYOZO
IPC: H01H33/42
Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To improve the withstand voltage performance to allow the miniaturization by setting the outer diameter of the glass single fiber of a glass bar using a glass fiber reinforced resin containing glass fiber and epoxy resin to a specified value range. SOLUTION: A glass fiber 4 vertical to the section of an operating rod is formed of a number of glass single fibers 4a braided cross. The circumference of the glass single fiber 4a consists of a hardened epoxy resin 5 which contains glass fibers parallel to the section. In this case, the linear expansion coefficient of the glass fiber 4 is differed from that of the epoxy resin, and when the epoxy resin 5 impregnated at high temperature is hardened and cooled to room temperature, a thermal stress is generated by the temperature difference. Since the epoxy resin 5 around the glass single fiber 4a is micro-cracked when this difference is large, it is necessary to regulate the thickness of the glass single fiber 4a.  Namely, the outer diameter of the glass fiber 4a is set to 1 μm or more and 5 μm or less, whereby the withstand voltage performance can be improved to reduce the electric insulating length of the operating rod.

Title: Continuous cutting apparatus for metal plate

IPC: B23D19/06
Filed: 1991-02-28
Abstract: PURPOSE:To make unnecessary the use of any universal shaft and make small the width dimension of the continuous cutting apparatus for metal plates, by connecting an end portion of each cutter shaft to a gear transmission mechanism, and making free the transmission of a rotating force in this gear transmission mechanism irrespective of rise/fall of each cutter shaft. CONSTITUTION:When cutting a metal plate, a lower-cutter shaft 23 and an upper-cutter shaft 18 are moved toward each other, and outer peripheral edges of the ring-like cutters 20 supported by and fixed to respective outer peripheral surfaces of both the cutter shafts are meshed with each other. By rotating a drive gear in this condition, a lower ring gear and an upper ring gear are rotated reversely from each other, by which a lower displacement gear 46 and an upper displacement gear 47 respectively meshed with a first internal tooth unit and a second external tooth unit on the inner peripheral edge of each ring gear are rotated reversed from each other, thereby causing mutually opposite rotations of a lower drive shaft and an upper drive shaft to which the displacement gears are fixed. Since, as a result, the lower-cutter shaft 23 and the upper-cutter shaft 18 are rotated, respectively, in opposite directions, feeding of a metal plate between the two cutter shafts would result in division of the metal plate.
