Inventor: SHIBATA KATSUMI
IPC: B66B23/06
Filed: 1990-06-26
Abstract: PURPOSE:To increase safety by making the rails of a moving handrail in a corrugated form, and thereby making the average speed component of each moving handrail in the direction of the rail of steps equal to the moving speed of the steps in the straight line part, and equal to the angular velocity of the steps in the curved part. CONSTITUTION:As the moving handrail 11, the handrail same as that of a normal straight line man conveyer is used, but a guide frame to guide the moving handrail is made in a corrugated form, and thereby the handrail 11 moves along the corrugated rails. The speed component of the moving handrail 11 in the rail direction of the steps 1 varies a little depending on the positions, and in the average observation, it is made equal to the steps 1 on the straight line part, and its angular velocity is made equal to that of the steps 1 on the curved part. As a result, it is unnecessary to use a flexible moving handrail as in the conventional way, and thereby, an expensive manufacturing cost and a short service life can be prevented, and the safety can be improved.

Title: Construction of water collection well
Inventor: UTSUNOMIYA HIROMITSU
IPC: E02B11/00
Filed: 1982-09-22
Abstract: PURPOSE:To prevent the collapse of the wall of excavated pit by a method in which sponge is attached to whole peripheral surface of each of liner plates, and the liner plates are assembled. CONSTITUTION:After the ending of excavation for one liner plate section, liner plates whose periphries are bonded with a sponge of a thicknss larger than an extra-excavation width are assembled. These operations are repeated. Since the thickness of the sponge is larger than the extra-excavation width, it follows that the sponges come to press the wall face along the undulatory surface shrunk between the liner plates assembled while pushing toward the outside slightly and the wall face of the excavated pit, thereby preventing the collapse of the wall face. Since the sponges have a high water permeability, no trouble occurs with the permeation of water.
