Title: Fiber reinforced ceramic molded body and production thereof
Inventor: NAKAMOTO TAKASHI
IPC: C04B35/486
Filed: 1988-03-02
Abstract: PURPOSE:To produce a fiber reinforced ceramic molded body wherein generation of breakage and crack is prevented by preparing ceramic slurry in which fibrous ceramic is uniformly dispersed and molding it with a mold having a prescribed shape, dehydrating and drying the molded body. CONSTITUTION:In the case of a silicon nitride-series ceramic molded body ae an example, slurry having about 40-60vol.% concn. is prepared by uniformly dispersing a mixture of >=50wt.% Si3N4 powder (about 0.01-3mum mean particle diameter) and <=50wt.% (Al2O3+Y2O3) in which fibrous Al2O3 is about 0.1-30wt.% and powdery Y2O3 is about 0. 1-50wt.% in water or NH4OH. Further fibrous Al2O3 is regulated to about <=10mum mean diameter and to about 10-500mum fiber length. Then this slurry is cast into a mold made of gypsum, etc., and dehydrated and thereafter the molded body is released from the mold and sufficiently dried and sintered as the molded body free from breakage and crack. Thereby the ceramic molded body improved in mechanical strength, elongation and resistance to strain is obtained.

Abstract: PURPOSE:To decrease impact forces applied to rotating members by disposing a locking member on a fixed plate provided to one of the halves of a locking device, and disposing a hinge member, a spring member and a damper on the respective portions of the other half. CONSTITUTION:A rotating piece 19 is disposed on a fixed plate 12, and when a protrusion 26 is inserted into an engagement lock hole 14 and a slide lock claw member 15 is engaged in the engagement hole 27, a bag 100 is locked and closed. When an unlock control knob 16 is slid, the slide lock claw member 15 is disengaged from the engagement hole 27 and the bag 100 is unlocked and opened. To lock and close the bag again, the rotating piece 19 is rotated and then the rotating piece 9 is smoothly rotated at constant speed in the same manner as when the bag 100 is opened. Then the protruding portion 26 is inserted into the engagement lock hole 14 again and the slide lock claw portion 15 is engaged in the engagement hole 27 whereby the bag is locked and closed. The control of opening and closing the bag can thus be carried out quietly and so product values can be increased.

Title: Guide device of elevator
Inventor: KAWAGUCHI TAKEYOSHI
IPC: B66B3/00
Filed: 1997-03-05
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive device by which a boarding miss of passengers and a deviation a rumbling position can be prevented by simultaneously rumbling upper and lower rumbling devices of a car when a door is opened. SOLUTION: When a door is opened when an elevator stands by, relay contact points 1A and 1B are closed, and a rumbling device 4 above a car and a rumbling device 5 under the car simultaneously rumble. At ordinary operation time, when the elevator arrives with directionality of the upward direction, a relay contact point 2 is closed, and the rumbling device above the car rumbles. When the elevator arrives with directionality of the downward direction, a relay contact point 3 is closed, and the rumbling device under the car rumbles. By such constitution, even if the whole elevators are arranged in an invisible position in a place where plural elevators are arranged, since the rumbling devices rumble when the door is opened, a boarding miss of passengers can be prevented.  Since the upper and lower rumbling devices 4 and 5 are made to simultaneously rumble when the door is opened at standby time, a deviation between upper and lower rumbling sounds can be prevented.

Title: Method for making lawn field
Inventor: MATSUNO TAKAAKI
IPC: A01G13/00
Filed: 1990-02-28
Abstract: PURPOSE:To make lawn on gold field, garden and ground in simple operation and low cost by embedding seedling lawn or lawn seed in the ground and applying asphalt emulsion to the ground surface. CONSTITUTION:Seedling lawn or lawn seeds are embedded in the ground and then an asphalt emulsion is applied to the surface to make the lawn field. The mutual bonding force in the asphalt emulsion weakens with passage of time and the asphalt changes to fine grains or a state attached to sand and further is decomposed by ultraviolet ray or soil-in bacterium, etc. Therefore, there is no difference, compared with lawn in which asphalt emulsion coating is not carried out. Consequently, it is made unnecessary to carry out sheet removing operation such as a conventional sheet stretching method, and becomes convenient, compared with the conventional sheet stretching method incapable of carrying out water sprinkling and additional fertilization, because water and fertilizer dissolved in water permeate through the asphalt emulsion layer into soil.
