A shred-resistant and cut-resistant absorbent sheet material including an absorbent substrate and cut-resistant particles discontinuously distributed through the substrate. The absorbent substrate can comprise cellulosic material and the particles comprise polymeric materials having an average size of at least about 100 nanometers, and most preferably between 100 nanometers and 1000 nanometers. In one embodiment, the particles are provided in an amount of between about 10 percent to about 50 percent by weight of the sheet. The sheet material can be made using typical paper making processes. Heat and / or pressure are applied to the sheet material to cause the particles to at least partially flow, so as to bond to the absorbent substrate. The sheets can be provided as a layered structure with a slip-resistant base for home use in the preparation of foodstuffs.

The invention discloses a method for integrally casting a more-than-25-ton large-sized diesel engine V-shaped body by utilizing nodular cast iron. The method comprises the following steps of A1, smelting the nodular cast iron in a smelting furnace, and adding bariumsili and metallurgical carborundum pretreatment agent after the smelting; A2, placing a spheroidizing agent into a bottommost layer of a dam-type spheroidizing ladle, utilizing a nucleating agent to cover a second layer, and utilizing a low-maganese low-alloy broken steel sheet to completely cover and compact a third layer; A3, adding a calcium-barium nucleating agent, charging the melted iron in one step to carry out the tapping metal-stream inoculation, realizing the nucleating effect while carrying out the spheroidizing treatment on charged melted iron, and carrying out the pouring pretreatment on the melted iron in the ladle; A4, placing the metal-stream inoculation agent into a funnel to carry out the pouring metal-stream inoculation; and A5, finally pouring the melted iron with the temperature being more than or equal to 1400 DEG C into a sand box, forming a cast by mold filling and solidifying the melted iron under the feeding of the feeder head liquid metal, and carrying out the heat treatment by utilizing the waste heat of the cast.

A multi-layer piezoelectric element having high durability wherein the internal electrodes and the external electrodes do not break even when operated continuously over a long time under high electric field and high pressure is provided.The multi-layer piezoelectric element comprises a stack formed by stacking at least one piezoelectric layer and internal electrodes consisting of first and second internal electrodes one on another, and external electrodes formed on two side faces of the stack with one of which being connected to the first internal electrode and the other external electrode being connected to the second internal electrode, wherein the external electrodes contain a conductive material and glass, the side whereon the external electrode is formed has cleft which has a wedge which contains glass formed therein, and the cleft is filled with the glass contained in the wedge and glass contained in the external electrode.

In a method of working a crystal, when a nitride semiconductor crystal is worked, voltage is applied between the nitride semiconductor crystal and a tool electrode to cause electrical discharge, so that the crystal is partially removed and worked by local heat generated by the electrical discharge.

The invention discloses automatic cutting equipment for a bar type material continuous discharging system. The automatic cutting equipment is mainly used for the bar type material continuous discharging system and is structurally characterized by being arranged at the material outlet of the bar type material continuous discharging system, wherein a supporting mechanism is arranged in front of the material outlet, and a guide slot is fixedly arranged above the supporting mechanism; a position sensor is arranged at the periphery of the guide slot; a transmission mechanism is positioned below the supporting mechanism; a material moves forward along the guide slot on the supporting mechanism by virtue of the material outlet; when the material reaches at a set length, the position sensor sends out an effective signal, an electrical control system drives the automatic cutting mechanism to cut off the material; meanwhile, supporting plates on the supporting mechanism move back to perform blanking, so that the material is regularly discharged on a blanking plate, and the transmission mechanism drives the blanking plate to discharge the material, by parity of reasoning, so that the automatic cutting and discharging of the material can be realized. By utilizing the high degree of automation and low manufacturing cost of the equipment, the defects of low efficiency and low cutting precision of existing manual operation can be improved.

Provided is a method for producing a flexible film (a diced laminate) that has a smooth torn surface and does not undergo the breakage of a thin glass contained therein by cutting a laminate comprising the thin glass and a resin layer. The method for producing a flexible film according to the present invention comprises cutting a laminate which comprises a thin glass having a thickness of 100 μm or less and a resin layer arranged on one surface or both surfaces of the thin glass. The method comprises the steps of: forming a groove on the outer surface side of the resin layer; and cutting the laminate along the groove.
