Abstract: The peeling member is disposed inside the inner tank. The switching mechanism is provided for switching between the state of rotating the peeling member in the interlocking manner with the inner tank and the state of being disconnected the peeling member from the inner tank. With the peeling member disconnected from the inner tank, one of them is rotated, the used paper diaper stored is peeled off from the inner surface of the inner tank, and then, the used paper diaper processed in the processing tank is discharged from the bottom of the processing tank to the take-out unit via the opening and closing unit.

Abstract: Provided is a used paper diaper processing apparatus in which a water absorption function of a superabsorbent polymer that absorbs water contained in excrement is lowered and water is removed by mixing the superabsorbent polymer and a chemical containing divalent metal ions in an outer tank, and in which weight is reduced by dehydration after an amount of water contained in a used paper diaper is lowered. In the apparatus, a lower portion of the outer tank can be opened and closed, so that weight reduction processing and a series of operations including taking-out are possible. Since an operator is not required to take out the used paper diaper after processing directly from the outer tank, it is possible to reduce work and hygiene burdens on the operator.

Abstract: A used paper diaper processing apparatus includes at an upper portion of a processing tank, a plurality of holding units capable of holding used paper diapers, and a continuous put-into unit including a holding unit rotation drive unit that rotationally drives each of the holding units at a put-into position I above an opening connected to the processing tank and a standby position II other than the put-into position. When the holding unit is rotated by the holding unit rotation drive unit and positioned at the put-into position, the used paper diaper held by the holding unit is put into the processing tank from the opening.

Abstract: A processing liquid is generated by mixing a chemical and water in a processing liquid generation region disposed below an inner tank. By further supplying water to raise a water level, the processing liquid is supplied from below the inner tank. This prevents a used paper diaper from coming into contact with water containing no chemical.

Abstract: In a processing tank where a processing liquid is stored up to a first water level, first stirring processing that removes water from a used paper diaper is performed to remove the water from the used paper diaper. Then, the processing liquid is stored up to a second water level higher than the first water level, and second stirring processing that separates excrement contained in the used paper diaper from the used paper diaper is performed to separate the excrement from the used paper diaper. After that, dehydration processing is performed.

Abstract: A method is provided for manufacturing a high-precision mold whereby a feature matching a desired feature design is carved into a hard mold material (41) using, for example, a diamond grinding wheel and/or a diamond turning point. Inherent imprecision and errors (49) introduced by the use of the grinding wheel/turning point are measured to determine deviations from the desired feature design. An ultrafast shortpulse laser is then activated to desirably ablate the deviations, thereby correcting the errors and conforming the feature to the desired shape. Furthermore, a thin film (1602) may be formed over the feature either prior to or after the laser ablation process, where the error measurement and laser ablation processes detects and ablates errors on the surface of the thin film, respectively. Additionally, the laser ablation process may be applied directly to, for example, an optical lens (1400) formed from an imprecise mold to remove any errors and imperfections thereon.
