In a urine receptacle of an automatic urine disposal device, a urine backflow prevention sheet, with no water permeability, having funnel-shaped pores, is placed between a top sheet and a urine absorbing sheet. A pair of rectangular electrodes, constituting a urine detection sensor, is glued onto an electrode support sheet and is placed between the top sheet and the urine backflow prevention sheet. A plurality of funnel-shaped pores is formed on the urine backflow prevention sheet.

Automatic urine disposal device and urine receptacle used therefor

A wearer wears a urine receptacle in which a urine absorbent materialis housed in a substantially rectangular, non-breathable, liquid-impermeable outer sheet having a U-shaped cross-section, and the surface of the urine absorbent material is covered with a hard-breathable, liquid permeable top sheet. Urine is discharged from a urine drainage port formed on the bottom surface of the outer sheet to a sealed urine tank by a vacuum pump through urine drainage tubes.

An automatic urine disposal device has a urine collecting pad, vacuum pump, and urine tank. In the urine collecting pad, the top sheet comes in contact with the wearer's skin, the hydrophilic sheet is disposed on the bottom of the top sheet, and the urine absorbent sheet is disposed at the bottom. When discharged urine flows in the top sheet, the hydrophilic sheet widely diffuses urine to saturate its entire surface and then becomes non-breathable. As the vacuum pump vacuums the air from the urine tank, urine is directed from a urine drainage port of the urine collecting pad via a urine drainage tube to the urine tank which is a sealed container.

A urine receiver which is sanitary, easy to attach, and furthermore, prevents urine leakage even when a wearer repeatedly changes positions is provided. A urine receiveris implemented in a urine collection processing system wherein urine discharged from the wearer is suctioned into a urine tank via a urethral tube. The urine receivercomprises, at the least: a liquid permeable, air-impermeable sheetwhich is placed opposite of and covering the urethral meatus of the wearer; a leak-proof sheetwhich is placed on the surface of the air-impermeable sheetopposite to the urethral meatus and bonds to the outer border of the air-impermeable sheet; a suction partwhich is provided between the air-impermeable sheetand the leak-proof sheetand to which the urethral tubeis connected; and a gathers partfor sealing the space between the air-impermeable sheetand the wearer's skin surface which is provided on the outer border part of the air-impermeable sheeton the urethral meatus side.

A string wireless sensorcomprising a wireless sensorincorporating the transmitting portion, which transmits electric signals by wireless and a string holder (polymer) which holds the wireless sensor at a certain distance.

String wireless sensor and its manufacturing method

In a double toothed type scroll compressor, spiral wraps are formed on both sides of an end plate of an orbiting scroll, and wraps adapted to engage with the spiral wraps are formed on a stationary scroll. A dust wrap is formed on a side diametrically outside of the wrap of the stationary scroll. Grooves are formed on ends of the respective wraps to receive therein seal members formed of a high polymer material. Electric charge of static electricity produced when the seal members slide on surfaces of the mating end plate is made to flow from a bolt provided on an end of a crankshaft to the stationary scroll through a brush, thereby preventing accumulation of electric charge in a crankshaft.

A decoloring apparatus for an image forming material comprising means for bringing a solvent into contact with an image forming material formed on a paper sheet and containing a color former, a developer and a decolorizer, and means for removing a residual solvent from the paper sheet.

Apparatus for processing paper sheets to decolor an image formed thereon

A paper classification apparatus includes a heater for heating paper or a solvent supply unit for supplying a solvent to the paper, a detector, a computer, and a selector guide. The detector detects the reflection density of the paper after being heated or supplied with the solvent. The computer compares the detected reflecting density of the paper with a predetermined reference value stored in a memory. The selector guide classifies the paper on the basis of a comparison result of the reflection density. This apparatus can classify plain paper having an image formed with an ordinary image forming material, plain paper having an image formed with an erasable image forming material, and thermosensible paper.

Paper classification apparatus

A method of decoloring an image formed on a paper sheet by using an image forming material containing a color former, a developer and a decolorizer, comprising the steps of bringing a solvent into contact with the image forming material for decoloring the image, and removing the residual solvent from the paper sheet.

Decoloring method of decolorizable image forming material

An image forming material formed on a paper sheet and containing a color former, a developer and a decolorizer, is decolored by heating of the image forming material, contacting the image forming material with a solvent optionally containing a decolorizer, and removing a residual solvent from the paper sheet.

Method of decoloring an image forming material formed on a paper sheet

An erasable image forming material includes a color former, a developer, and a decolorizer and is erasable by contact with an erase solvent. Free energy &agr; required for the decolorizer and the developer to form a complex and free energy &bgr; required for the color former and the developer to form a complex have a relationship represented by &agr;&lE;&bgr;&lE;10 Kcal/mol.

Erasable image forming material

An erasable image forming material includes a color former, a developer, a binder resin, and a polymer decolorizer having an electron donating group capable of physically or chemically adsorbing the developer. This polymer decolorizer is, e.g., a polymer compound having a sugar skeleton, representatively starch. This image forming material can form sharp images and erase images by heat or a solvent to achieve a good erased state.

A displacement type fluid machine in which a displacer and a cylinder are disposed between end plates, a space is formed by an inner wall surface of the cylinder and an outer wall surface of the displacer when the center of the displacer is put on the center of the cylinder, and a plurality of spaces is formed when the positional relationship between the displacer and the cylinder is for a gyration, is restrained from deterioration of the efficiency. One of the end plates and a vane protruding inwardly from the inside surface of the cylinder are fixed to each other so as to restrain the deformation of the vane and decrease the leakage of a working fluid due to the deformation.

A negative photosensitive polymer composition, which comprises a thermosetting polymer precursor which can be cured through cyclodehydration upon heating, and a photosensitive heat cure accelerator which is capable of accelerating a curing upon irradiation of light (cyclodehydration accelerating property). This photosensitive heat cure accelerator may be a compound which is capable of increasing molecular weight and raising volatilization temperature upon irradiation of light, or a compound which is capable of generating a carboxyl group upon irradiation of light thereby exhibiting a heat cure-accelerating property, and is formed of an aromatic hydrocarbon or aromatic heterocyclic compound having at least one hydroxyl group, substituted or unsubstituted amino group or mercapto group.
