Title: Parallel elevator system
Inventor: HIRAYAMA KAZUNARI
IPC: B66B7/00
Filed: 1988-06-07
Abstract: PURPOSE:To reduce the number of pieces of guide rails being installed in a lifting passage in addition as well as to simplify the execution of installation by supporting a portion of balance weights for two units of elevators parallelly installed, guidingly in the upper half part and lower half part of the guide rail for a balance weight of one unit portion in common, and forming them into such a structure as going up and down by half of a lifting distance of each cage. CONSTITUTION:Balance weights 9A, 9B for a portion of two units of elevators parallelly installed are guidingly supported by a guide rail 11C for a common balance weight, and they go up and down with the upper half part and lower half part of this guide rail 11C for the common balance weight by half of each lifting distance of cages 7A, 7B interlocking via each of ropes 6A, 6B. The guiding support of these balance weights 9A, 9B for a portion of two units gets off with the guide rail 11C for the balance weight for one unit like this, so that the number of pieces of the guide rail is reduced as much as a portion for that, and a lifting space for the balance weight for one unit in a lifting passage becomes useless so that the promotion of space saving is thus contrivable.

Title: V belt for power transmission
Inventor: HATTORI TORAO
IPC: F16G5/16
Filed: 1987-06-05
Abstract: PURPOSE:To prevent the occurrence of relative abrasion and high stresses in a band, and to facilitate the assembling operation by forming mutually contacting surfaces between adjacent V-shaped metallic members so that the circular-arc-shaped protruded part of the member on the end surface in the longitudinal direction of the band is brought into contact with the perpendicular plane part of the adjacent member. CONSTITUTION:The mutually contacting surfaces between adjacent V-shaped metallic members in a band are so formed that the circular-arc-shaped protruded part 2a of the member on one end surface in the longitudinal direction of the band is brought into contact with the plane part 2d of the adjacent V-shaped metallic member. Thus, the circular-arc-shaped protruded part 2a is abutted on the mating perpendicular plane part 2d without having any clearance between the adjacent members, and the band is prevented from becoming in a polygonal state, and further the occurrence of high stresses on the inner surfaces of the band is prevented to reduce the abrasion of the belt and to prolong the lifetime effectively. And, since the lower side of one surface of the band fitting part has a sloped surface 2e, and the outer side 2f thereof is recessed from the circular-arc-shaped protruded part 2a, the V-shaped members have flexibility to be warped in both upper and lower directions, and further the V-shaped metallic member to be assembled last can be easily fitted together.

Abstract: PROBLEM TO BE SOLVED: To pour a beverage into an inner container while a plug member is kept attached to an outer container and to improve pouring operability by forming a pouring passage capable of directly pouring the beverage into the inner container at the plug member in a vacuum bottle for which the inner container is provided inside the outer container and the plug member is attached to the upper opening part of the outer container. SOLUTION: In the case of pouring the beverage into this vacuum bottle 1, an upper lid 30 is opened first. Then, since the inside and outside of the plug member 5 are communicated by the pouring passage 19, the beverage is poured into the inner container 3 through respective elements 20, 19, 24 and 23 while the plug member 5 is kept attached to the outer container 2. Also, a beverage temporary storage part 20 is formed at the upper part of the pouring passage 19 and thus, the beverage is prevented from overflowing from the upper part of the pouring passage 19 at the time of pouring. Further, when the fixation of the plug member 5 is completed, since the pouring part 18 of the plug member 5 and the pouring part 10 of the outer container 2 face each other, smooth pouring is secured.  Further, by clogging the upper opening part 4 by a movable inner lid 22, the taste of the beverage is prevented from being damaged.
