Title: Crawler work vehicle
Inventor: HIDAKA SHIGEMI
IPC: B62D11/18
Filed: 1999-12-08
Abstract: PROBLEM TO BE SOLVED: To prevent a steering mechanism alone from driving a traveling crawler when a traveling transmission is in a neutral position and the traveling crawler remains stationary, simplify steering control, and improve a steering control function by maintaining a straight- ahead position of a traveling crawler steering control that employs a steering mechanism when a traveling crawler transmission control is in a neutral position. SOLUTION: This vehicle is provided with a hydraulic type continuously variable transmission mechanism for traveling ('transmission mechanism') that drives right and left traveling crawlers in the same direction at the same speed and a hydraulic type continuously variable transmission mechanism for swiveling ('steering mechanism') that drives the right and left traveling crawlers in a direction opposite to each other at the same speed. Even if one of these mechanisms is operated when a main transmission lever 68 and a steering wheel are held in a neutral position, it simply causes a first and a second main shaft 77, 79 to move circularly either forward or backward with no operating force acting on joint shafts 88, 89. When the transmission control is in the neutral position, steering control by means of the steering mechanism is maintained at the straight-ahead position.  Even if the steering mechanism alone is operated when the vehicle remains stationary with the traveling transmission in the neutral position, therefore, the steering mechanism is prevented from driving, steering control is simplified, and the steering control function is improved.

Title: Method for separating foamed plastic base of panel from adherend and device therefor and foamed plastic base best suited for separation
Inventor: OGURA HIDEO
IPC: B29B17/02
Filed: 1998-12-08
Abstract: PROBLEM TO BE SOLVED: To ensure safety and prevent an environmental contamination from being generated by heating a panel with an adherend such as a photograph or a poster applied to the surface of a foamed plastic base to shrink the foamed plastic base and separating the adherend from the base. SOLUTION: A foamed base 1 of a thermoplastic synthetic resin undergoes a secondary foaming process at a temperature above a thermal deformation temperature and gradually begins its thermal shrinkage to generate a shearing force due to the difference in the degree of thermal shrinkage in an interface 3a between the foamed base 1 and the adherend 2, and begins separating from the adherend 2. Until a separation shearing force works between the base 1 and the adherend 2, the base 1 is heated so that the degree of thermal shrinkage in the longitudinal and the width direction of the base 1 is about 10% or more. However, it is possible to increase the degree of thermal shrinkage by increasing the heating temperature and prolonging the heating time.  Since there are an optimal temperature and an optical heating time for the separation of the adherend from the base 1, both are previously set and after heating, a cold air is blown to the base 1 or some other means are employed for this purpose to promote the separation between the base 1 and the adherend 2. Thus it is possible to reuse the base 1 as a raw material and discard the adherend 2 as a common waste and therefore, ensure a safe and almost environment contamination-free treatment.

Title: Method for treating clean water
Inventor: INOUE SHIRO
IPC: C02F1/28
Filed: 1997-12-18
Abstract: PROBLEM TO BE SOLVED: To provide a method for treating clean water wherein when suspended matter substances are drawn out of a tank, only the suspended matter substances can be selectively drawn out without being accompanied by active carbon. SOLUTION: A filter membrane unit 3 is immersed in an original water in a treating tank 1 and particulate active carbon 2 on the surface of which aerobic microorganisms are stuck is immersed on the outside of the filter membrane unit 3 in the treating tank 1. Air is blown into the original water below the filter membrane unit 3 to generate a circulation flow of water which ascends in the filter membrane unit 3 and descends its outside in the treating tank 1 by air lift effect. Making hazardous substances harmless by decomposition in the original water and removal of suspended matter substances are performed thereby. A supporting material 12 including a porous plate for preventing the active carbon 2 from descending is disposed in the descending flow path for the original water and the active carbon 2 is packed on the supporting material 12.

Title: Work fixing device
Inventor: TOMITA TERUHIKO
IPC: B23Q3/06
Filed: 1998-12-09
Abstract: PROBLEM TO BE SOLVED: To strongly and positively fix a large scale heavy equipment such as a metal mold. SOLUTION: Wires 9 and 10 are connected therewith via pulleys 11 and 12 over the upper surface of a U-shape type brace 5 and underneath the lower surface of a slide block 7. The wires 9 and 10 are connected with a revolving shaft 13a or a cam 14 to be moved up and down together with an arm 13. By this constitution, when the arm 13 is grasped by an operator so as to be raised up, the U-shape type brace 5 is thereby lowered down, and when the arm 13 is lowered down, the U-shape type brace 5 is raised up. In a state that the U-shape type brace 5 abuts against a metal mold 4, the U-shape type brace 5 merely abuts against the upper surface by the force of the operator, and sufficient pressing force for firmly fixing the metal mold 4 is not incurred. Accordingly, by taking up the wire 10 to the cam 14 with the arm 13 revolved, the tension of the wire 10 is increased. Just then, the U-shape type brace 5 and the slide block 7 are strongly pulled down by the wire 10, so that sufficient pressing force for firmly fixing the metal mold 4 can be incurred.
