Title: Side-ditch lid handling tool
Inventor: YAMADA YOSHIHIRO
IPC: E03F5/04
Filed: 1991-12-16
Abstract: PURPOSE:To prevent the fall of a side-ditch lid and facilitate its movement in the lifted state. CONSTITUTION:A pair of hooks 50, 60 and curved end parts 51, 56 are applied to a side-ditch lid. When a lever 75 is rotated, a pressing member is rotated while pressing the hook 60 against the elastic force to move the hook 60 in the direction of reducing the space between the hooks 50, 60, and the rotation is stopped in a point where the cross point angle with the tangent of the pressing member pressing the hook 60 is passed through a right angle. When the side-ditch lid is nipped by using the elastic force of the hook 60, the elastic force never form a reversed rotating force through the pressing member, the elastic force is transmitted to the side of the member stopped, and the side-ditch can be separated from the hooks 50, 60 only when the lever 75 is rotated to release the hook 60. Therefore, the side-ditch lid can be carried to a determined designation by holding grip parts 41 on both ends of a carrying member 40 by two persons, and the side-ditch lid is never separated nor falls from the hooks 50, 60 on the way of carrying.

Title: Air quantity control device for organic waste treating device
Inventor: SUZUKI JOJI
IPC: B09B3/00
Filed: 1995-11-29
Abstract: PROBLEM TO BE SOLVED: To prevent dusts from blowing out and to prevent an organic waste from decaying in a disposal tank by operating an air feeding blower in a min. resolving state after the lapse of a revolving time of the air feeding blower by a timer thereby controlling an air quantity to a treating layer. SOLUTION: When a charging quantity of the organic waste is normal, a normal operation start which 64 is depressed, and when the charging quantity is max, a max. operation start switch 88 is depressed. At this time, a blower motor 46 is driven in an intermediate frequency or max. frequency by an invertor 102. With the lapse of respective specified times, after a start of a normal operation, or after a start of a max. operation, the operation is subject to a min. operation state. Thus, the rotation state of the air blower and rotation time are controlled in accordance with the charging quantity of the organic waste, and the organic waste is dried adequately. Also even though the charging quantity is different, since the secondary treatment is executed quately, and the blower is rotated at min., the waste can be prevented from decaying even when the organic waste in a primary and secondary treating tanks is left standing.
